How GIS Improves the Process of Citizen Science

Researchers, Artists, and Technologies Engage with Local Groups Using Computer Mapping

Citizen science is an increasingly popular activity among a broad cross section of the population. Because the number and variety of opportunities for participation continue to grow, it is appealing to those in a widening range of age and physical ability. Participants have joined diverse scientific monitoring projects, including migratory bird studies and personal weather station observations, as well as provided their unused computer time for interstellar space exploration. Citizen science has even stimulated growth in the ecotourism industry.

Patrick Rickles at al 2“Regardless of their background or level of skill, citizen science provides people with a powerful platform that allows them to get involved in science and their environment,” says Patrick Rickles, research associate for the Extreme Citizen Science (ExCiteS) research group at University College London (UCL). “However, as valuable as this is, these programs often see the citizen as a passive participant that simply collects information and then hands it over to the researcher. At that point, their involvement in the project is considered complete.”

Recognizing the potential for change provided by greater engagement with citizen scientists, Muki Haklay, UCL professor of geographical information science (GISC), and Jerome Lewis, a UCL lecturer of anthropology, formed ExCiteS. This is an interdisciplinary group composed of researchers, artists, and information and communication technology specialists that work with local groups to better engage them in the process of citizen science through participatory action.  Continue reading

The Paleo Diet Belongs in Caves: What You Really Need to Know About Diets

Editor, Science Education

Diets provide a great opportunity to exercise critical thinking. Pick any diet and pick it apart. Do this as a mental exercise or, if you teach, with your classes. Chances are that many of your students’ parents have dieted or are dieting. In this article, I am picking on the currently trendy Paleo diet.

The Paleo diet persists. I have a strange theory about diets. The first part is that people don’t like to diet. They like to eat whatever they choose. I suspect that this is especially true of libertarians. The second part is that many people see their food as a health problem and would like to change their eating patterns.

Many years ago, the Grapefruit Diet was very popular. This was great for people who loved grapefruit but not so much for those who found them too sour or too messy. Then, there was the problem that grapefruits are like the proverbial Chinese dinner that left you hungry shortly after finishing it. “Have another piece of grapefruit” just doesn’t work for most people.

Anyway, my theory is that diets are successful not if they work but rather when they cater to people’s desires. If you could get away with an ice cream diet, you’d have the world doing it because “everyone likes ice cream.” I haven’t yet seen a broccoli diet even though it would probably work better than grapefruit.  Continue reading

The End of Dark Energy

Dr. Peter A. Milne and his associates have found an unexpected and, to the cosmological community, startling result from their surveys of supernovae. This result illustrates both the consistent and varying nature of science at the same time.

Dr. Peter Milne

Dr. Peter Milne

We know from a great many astronomical observations that the universe has been expanding for a little short of 14 billion years and continues to expand. Because of gravity, everyone expected that this expansion was slowing over time with theories and measurements suggesting that this expansion would eventually coast to a very dilute universe drifting apart at ever slower speeds.

In the 1990s, some astronomers separately discovered that the universe is expanding ever more rapidly instead of the expected opposite slowing of expansion using measurements of he brightness of very distant supernovae. They received the Nobel Prize in physics for this work in 2011.

Stars can explode. One common explosion is called a nova. A much more cataclysmic and extremely brighter explosion is a supernova. Supernovae shine with a brightness that can exceed that of all of the hundred billion or so stars in its galaxy. For this reason, we can see them in distant galaxies that are barely visible in our best telescopes. A supernova is a rare event occurring about three times a century in a galaxy the size of our Milky Way. With hundreds of billions of galaxies, however, it’s not too hard to find hundreds each year using modern astronomical equipment.

A special sort of supernova created when the two stars in a binary star system go through a specific series of interactions is known as a type 1a supernova. Because of the steps required to reach supernova status, the brightness of these type 1a supernovae has been considered to be a constant that can be used to estimate distances to very distant galaxies. Brightness declines with distance in a very precise manner.

There remains the possibility that acceleration of very distant bodies in our universe away from each other is a basic property of our space-time structure not detectable at smaller distances of only millions or even tens of millions of light-years, that “dark energy” is just an attempt to recast a phenomenon into understandable terms, just as the caloric theory of heat was long ago. -HK

The measurements of these supernovae were the reason to believe that the expansion of the universe was accelerating. We are seeing these very distant supernovae with light that started its journey over ten billion years ago when the universe was very young. Dr. Milne has discovered that type 1a supernovae are not all the same but fall into two categories of different brightness. Furthermore, the supernovae from the early universe are, on average, less bright than those in the more recent universe.

The lower brightness of the distant supernovae may well be due to less inherent brightness instead of greater distance. This finding destroys a fair piece of that Nobel Prize discovery. Dr. Milne still attests that the universe’s expansion is accelerating, just not so fast, but the vast number of recalculations being done to account for this new discovery will take some time.  Continue reading

Dark Matter Clues

picture of Harry KellerBy Harry Keller
Editor, Science Education

You may have seen the headlines already. “What is dark matter made of? Galaxy cluster collisions offer clues,” shouts the Christian Science Monitor.1

Here you have a great moment to engage students in something exciting and to use critical thinking. Dark matter is a hypothesis to explain why stars in galaxies circle around their centers faster than the observable matter says that they should, as well as other more sophisticated reasons. It’s called “dark” because it does not emit light and because you cannot see it. You might also have called it “invisible” matter, but much matter seems invisible. Besides, “dark” implies spooky, and this stuff is definitely spooky because ordinary matter moves right through it as though it isn’t there, except for gravitational effects.

The new finding just reported tell us that dark matter behaves just the same way with itself. One patch of dark matter moves right through another as though it’s not there at all (again, except for gravitational effects). This result pushes back against the most popular idea about the identity of dark matter, that it’s WIMPs — weakly interacting massive particles — because particles don’t just pass right through each other.

Dark matter is invisible. Based on the effect of gravitational lensing, a ring of dark matter has been detected in this image of a galaxy cluster (CL0024+17) and has been represented in blue. NASA, ESA, M.J. Jee and H. Ford (Johns Hopkins University)

Two explanations come to mind. Some physicists doing the work still are seeking particles, but these other explanations could help get around that barrier. There are some truly exotic explanations going around as well, such as the existence of a “mirror universe.” It’s best to stick with the simplest ones, though. Occam’s Razor tells us so.

One explanation is that gravity just doesn’t work exactly as we expect it to, especially when dealing with very large masses spanning very large volumes of space. This is not a very popular explanation. The other is that dark matter is really energy. Because of the equivalence of energy and matter demonstrated by Einstein and captured in his famous equation, E=mc2, energy is affected by and causes gravity.  Continue reading

Mars One CEO Answers Questions About Mission Feasibility

Amersfoort, 19th March 2015 – Mars One recently published a video in which Bas Lansdorp, CEO and Co-founder of Mars One, replies to recent criticism concerning the feasibility of Mars One’s human mission to Mars.



Question: What do you think of the recent news articles that doubt the feasibility of Mars One?

BL: At Mars One we really value good criticism because it helps us to improve our mission. We get a lot of criticism from our advisors, and that is also exactly what we want from them. The recent bad press about Mars One was largely caused by an article on medium.com, which contains a lot of things that are not true. For example, the suggestion was made that our candidates were selected on the basis of how much money they donate to Mars One. That is simply not true, and it is very easy to find that on our website. There are a lot of current Round Three candidates that did not make any donations to Mars One, and there are also lots of people that did not make it to the third round that contributed a lot to Mars One. The two things are not related at all, and to say that they are is simply a lie. The article also states that there were only 2,700 applications for Mars One, which is not true. We offered the reporter, the first journalist ever, access to our list of 200,000 applications, but she was not interested in that. It seems that she is more interested in writing a sensational article about Mars One than in the truth.

We will have to delay the first unmanned mission to 2020. Delaying our first unmanned mission by two years also means that all the other missions will move by the same period of time, with our first human landing now planned for 2027. -B.L.

Question: Concerns have been voiced about the thoroughness of the astronaut selection process. What is your response to that?

BL: We started our astronaut selection with over 200,000 applications that were submitted online. The application included a video and a lot of psychological questions for our candidates. We used that to narrow down the candidates to about 1000 that had to do a medical check, which was very similar to the check for NASA astronauts. All the remaining candidates then underwent an interview. The interview and all other parts of the selection process were led by Norbert Kraft, our Chief Medical Officer. He has worked on astronaut selection for 5 years at the Japanese Space Agency, and at NASA he researched crew composition for long duration space missions.  Continue reading

Mars One Fizzles?

picture of Harry KellerBy Harry Keller
Editor, Science Education

One of the craziest schemes to garner worldwide publicity and lots of contributions is having some new problems. Mars One has lost one of its final hundred to misgivings about the process by which he was chosen. Will more come out with similar stories? Is this the beginning of the end for Mars One?

The Mars One stray is Joseph Roche, an assistant professor at Trinity College Dublin with a PhD in, wait for it, physics and astrophysics. With this education and background, he’s not just a scientist well equipped with Carl Sagan’s famous “baloney detection kit,” he’s also a specialist in getting around the universe.

Mars One is a reach too far. Until I see plenty of funding and until I see that water mission and then see the first supply mission land successfully, I will remain cautiously skeptical. -H.K.

I have written plenty about Mars One and its challenges. In the end, I stated that its biggest challenge is not radiation or water or air or food but money. It’s not just the money to send that first expedition to Mars but also the money to keep sending more until the colony is self-sufficient. The first expedition requires several preparatory flights to deliver lots of habitat modules, freeze-dried food, solar panels, machinery, rovers, and more. Each of those unmanned preparatory flights will cost very large sums of money, likely a billion or more dollars apiece.  Continue reading

Life on Frozen Moons

Editor, Science Education

Now that three of the moons of our solar system’s gas giant planets have been said to have subsurface oceans, it’s time to take stock and consider the meaning of these analyses.

Ganymede and Europa of Jupiter along with Enceladus of Saturn are likely to have oceans far below their frozen surfaces. Should we send unmanned missions to explore these unusual moons, and what should we be searching for? Many have exclaimed that we have extremophiles (organisms that survive in extreme environments) here on Earth, so we cannot discount the likelihood of life beneath miles of ice where the Sun never shines.

This image or video was catalogued by Jet Propulsion Laboratory of the United States National Aeronautics and Space Administration (NASA)

Enceladus’ north polar region. This image was catalogued by NASA’s Jet Propulsion Laboratory.

If we search near the geysers of Enceladus, might we find the frozen remnants of miniature fish coughed up from deep down inside this odd moon? Answering this question requires more than a moment’s thought. What is life? How does it begin and advance? Are the ingredients for life available in those cold, deep seas?

Here’s my definition. Life uses available energy and materials to reproduce itself and has the potential for errors in reproduction that will allow for evolution. From what we know, those vast, cold underground oceans have the necessary ingredients. Without an energy source, they would be frozen and not liquid. Heat coming from the inside of a moon must provide chemicals that can both be used as chemical energy sources and as materials for constructing living organisms.  Continue reading

MOOC Sightings 001: UNC and Cornell

MOOC Sightings2

Despite wholesale announcements by powerful academic leaders throughout the U.S. that MOOCs are dead, sightings continue to pour in from around the country and the rest of the world. For skeptics, the problem is physical evidence. People can offer them and take them, but no one seems to know what a MOOC looks like. Some point to Coursera and edX, but in the opinion of most MOOC experts, who are primarily from Canada and the UK, these are hoaxes.

So, in the interest of determining once and for all whether MOOCs are fo’ real, I’ll be opening Project White Book to publish promising sightings and photos of MOOCs. In this inaugural post, I’m sharing the photo, below, of what appears to be one person’s conception of a MOOC. I recently found it in the ETC spam queue. It was posted anonymously with the header “Da MOOC!” I’ll post photos as I receive them, so if you have one, email it to me (jamess@hawaii.edu) and I’ll publish the most interesting.

Is this a MOOC, a hoax, or just another weather-related phenomenon?

Is this a MOOC, a hoax, or just another weather-related phenomenon?

I’m also sharing promising sightings by Sarah Kaylan Butler, “50,000 Enroll in UNC Online Course” (Daily Tarheel, 2/19/15), and Blaine Friedlander, “Cornell Sinks Teeth into Four New MOOCs” (Cornell Chronicle, 2/19/15).

Butler reports that “almost 50,000 students have enrolled in a massive open online course on positive psychology taught by UNC professor Barbara Fredrickson.” Evidence that this Coursera-based course might be a real MOOC is very strong. It’s six weeks long, a departure from the usual quarter or semester time frame. It’s comfortably aimed at interest rather than college credit. According to Fredrickson, “Most people that are enrolled — 95 percent of them — say that they’re interested out of their own curiosity.” And the professor is on firm MOOC footing, looking for pedagogical guidance from the future rather than the past. She says, “I’ve written a couple of books for general audience and one of the things that’s clear about our changing audience is that people don’t necessarily want to read books, but they like ideas.”

Another promising sighting is from Cornell. Friedlander reports that “Cornell will offer four new [MOOCs] in 2016: shark biodiversity and conservation, the science and politics of genetically modified organisms (GMOs), an introduction to engineering simulations, and how deals get done – mergers and acquisitions principles.” They’re still in the planning stages, so I’ll keep an eye out for more details as they become available.

Are MOOCs fo’ real? In this series, I’ll be looking at the evidence through a lens that’s forged from constructivist and disruptive theory as well as a dash of whimsy. In this process, I look forward to hearing your thoughts. Please share them in the discussion below. If you’re logging in from an address that has been previously approved, your reply will be posted automatically. If not, your first reply will be published within 24-48 hours. Subsequent replies from your address will be published immediately.

Mars One: 100 Still in Running to Be First Humans on Mars

Amersfoort, 16th February 2015From the initial 202,586 applicants, only 100 hopefuls have been selected to proceed to the next round of the Mars One Astronaut Selection Process. These candidates are one step closer to becoming the first humans on Mars.

“The large cut in candidates is an important step towards finding out who has the right stuff to go to Mars,” said Bas Lansdorp, Co-founder & CEO of Mars One. “These aspiring martians provide the world with a glimpse into who the modern day explorers will be.”

The Mars 100 Round Three candidates were selected from a pool of 660 candidates after participating in personal online interviews with Norbert Kraft, M.D., Chief Medical Officer. During the interviews the candidates had a chance to show their understanding of the risks involved, team spirit and their motivation to be part of this life changing expedition.

Dr. Norbert Kraft said, “We were impressed with how many strong candidates participated in the interview round, which made it a very difficult selection.”

There are 50 men and 50 women who successfully passed the second round. The candidates come from all around the world, namely 39 from the Americas, 31 from Europe, 16 from Asia, 7 from Africa, and 7 from Oceania. The complete list of Mars One Round Three Candidates. Statistics on the candidates can be found here.

The following selection rounds will focus on composing teams that can endure all the hardships of a permanent settlement on Mars. The candidates will receive their first shot at training in the copy of the Mars Outpost on Earth and will demonstrate their suitability to perform well in a team.

New Exoplanets Very Old

Editor, Science Education

With all of the hoopla over exoplanet discoveries in recent years, it’s a big surprise that this one did not receive more attention. Kepler-444 is a small star, about 25% smaller than ours, and is 11.2 billion years old. According to measurements made by the 600-million dollar Kepler space telescope, it has five rocky planets ranging in size from Mercury to Venus.

The above information is sufficient to generate great excitement. When you realize that the universe is only about 13.6 billion years old, you know that this star and its planets formed in the early days of a very young, only about 2.5 billions years old, universe. Our own star is less than half as old at 4.6 billion years and has an expected lifespan of around 10 billion years.  Continue reading

The Science of Deflategate

picture of Harry KellerBy Harry Keller
Editor, Science Education

The New England Patriots have muddled up the Super Bowl in a grand fashion. It might as well be an MIT prank but on a national scale. We haven’t see the like since Caltech (MIT’s famous rival in the prank world) jimmied the Rose Bowl’s card stunts half a century ago. (Personal note: I was a member of the Caltech group of twelve that did that. Also see this LA Times article.)

Denials are not going to change any fan’s mind. If you’re a Patriot fan, you probably don’t think it’s important. If you’re not, then you will believe any evil of the New England dynasty.

Before delving into the science, I should note that reporters have said that the ball deflation was discovered during halftime and rectified. As the final score was 45-7, and the second half score was 28-0, even if every Patriot point in the first, seemingly flawed half were rescinded, the score would still be 28-7 in favor of the Patriots. We are not discussing, therefore, who should play in the Super Bowl. We are instead discussing how balls would have become low in pressure.

As any high school physics teacher will tell you, PV=nRT, the ideal gas law. Okay, that’s gibberish to many, but it’s really very simple. So simple in fact that you can do the calculations yourself with calculator or even readily with paper and pencil. Let’s deconstruct this equation.  Continue reading

‘Better Than Earth’? – Baloney

picture of Harry KellerBy Harry Keller
Editor, Science Education

“Superhabitable” worlds may be common in our galaxy, making ideal homes for extraterrestrial life — Scientific American cover, January 20151.

Years ago, Carl Sagan famously wrote about a scientist’s “baloney detection kit” in The Demon-Haunted World (1995). You can learn all about this storied chapter by searching on the Internet for “baloney detection kit.” His point was that scientists obtain this mental tool kit as a side effect of their training and that we should similarly train everyone.

Scientific American magazine just published an article, “Better than Earth,” which shows us that scientists are not immune from broadcasting baloney themselves at times. The article is really quite good and interesting. Its statements are, as far as we can tell, accurate. Where is the baloney then?

At one point, the article states, “[T]he more closely we scientists study our own planet’s habitability, the less ideal our world appears to be.” The article also faults our own star’s “short” lifetime of about 10 billion years. “By some 1.75 billion years from how, the steadily brightening star will make our world hot enough for the oceans to evaporate, exterminating any simple life lingering on the surface.”

Looks as though we evolved just in time to enjoy our planet for a billion years or so before we are all steamed to death. Slower evolution may not have left enough time for us to exist here.

We circle a G-class star. According to the author, the next step down in star size, “K dwarfs[,] appear to reside in the sweet spot of stellar superhabitability.” K dwarf stars will shine for tens of billions of years, many times longer than our star. However, the author cautions that our planet is too small for conditions suitable for life to exist for that long period of time. Our core would have cooled too much to sustain our magnetic field and plate tectonics, both necessary to life.  Continue reading

What Sort of Intelligence?

picture of Harry KellerBy Harry Keller
Editor, Science Education

You may have noticed recent news about Stephen Hawking predicting the demise of the human race due to the rise of artificial intelligence (AI)1. Others of genius rank, such as Elon Musk and Ray Kurzweil2, have also made this prediction. With “The Theory of Everything” (biopic about Prof. Hawking) in theaters right now, this prediction is resonating across the English-speaking world.

Before digging your shelters or heading for the hills, you should ask, “What is artificial intelligence?” A bit of history may help put this entire subject into perspective. The term was coined in 1955 by John McCarthy, who called it “the science and engineering of making intelligent machines.”3 “When?” you ask. “That’s nearly 60 years ago! Before I was born!” (I actually was born well before then, but statistically you probably weren’t.)

Funny how AI has not taken over the world in the 60 years it’s had so far. Why the sudden worry? Computers are becoming more powerful and less expensive. Computer memory is dirt cheap, speaking historically. This trend of more computer power and more memory shows no signs of abating soon. Could it eventually reach the tipping point where machines are sentient and self-reproducing? Would they then remove the “scourge” of humans from the Earth’s surface? Might the end be less dramatic in that they would render people superfluous? Imagine a world in which all work, including creative work, is done by machines. Who needs Beethoven when you have the Ultra-Composer Mark IV?

This entire discussion circles around to defining machine intelligence and estimating exactly how smart machines might become. Right off the bat, understand that intelligence, as we commonly understand it, has not been seen in machines yet. No one truly knows if it ever will be. To comprehend why, you must have a feeling for the nature of computers and computing.  Continue reading

Mars One: 10 Potential University Payloads to Mars in 2018

Amersfoort,1st December 2014 – Mars One is proud to present the ten Mars One University Competition finalists eligible to fly to Mars. One of these ten payloads will receive the once in a lifetime opportunity to fly on Mars One’s first unmanned Lander mission to Mars in 2018. For the first time ever the public will be able to decide which payload receives the extraordinary opportunity to fly to Mars.

The ten remaining projects from an initial 35 submissions were submitted by diverse universities worldwide. In order to get this far, the payload proposals needed to meet all requirements as described by Mars One supplier Lockheed Martin. Mars One community members, social media followers, and the general public will have the opportunity to vote on and select the winning payload. Voting opportunities for the public will be opened in the first weeks of December, 2014. Voting submission will be accepted until December 31st, 2014.

The winning university payload will be announced on January 5th, 2015. The winning payload needs to be feasible and meet the requirements and restrictions as outlined in the Proposal Information Package (PIP) and on-going discussions with Lockheed Martin, who will build the 2018 lander. Additionally, if in any case the winning team can not perform or adjust to additional requirements the runner-up will be chosen instead.

Arno Wielders, Co-founder & CTO of Mars One said, “These ten final projects are unique and creative and we are very happy with the payload proposals these teams have presented. It would be highly interesting to see each and every one of these projects being launched to Mars. Now it is up to the public to decide which project they would like to have on Mars.”  Continue reading

‘Big Hero 6’ Delights and Challenges

picture of Harry KellerBy Harry Keller
Editor, Science Education

Only a few true nerds, such as myself, will be at all challenged with Big Hero 6. Let me explain.

Big Hero 6 is about four students at San Fransokyo Institute of Technology (SFIT), the younger brother of a fifth, and a robot. These are the “6” in Big Hero 6. The catch here is that these “super heroes” don’t have mystical powers. Their performance boosts come from technologies that they create.

The lead character is Hiro Hamada (Ryan Potter) who is a wild genius youth who enjoys bot fights instead of the serious business of school. His older brother, Tadashi, tries to dissuade him from wasting all of his talent on underground bot fighting and finally breaks through. He gets Hiro hooked on being a student at SFIT. There’s a catch. SFIT is a robotics-oriented school, and you must show your ability to get in. Hiro must demonstrate his capability to the faculty of the school by showing actual robotics.

How he does so and what happens next set the course for the film. There’s just enough scariness and just sufficient levity associated with it to please school-age children. I’ll be taking my grandsons (aged five and seven) to see this movie two days after it opens and will share their reactions with you then.

The robot member of the six is the most unlikely hero you’ll ever meet. Baymax is voiced perfectly by Scott Adsit. He is a healthcare robot, a nurse, who looks like, as the script puts it, a marshmallow. He is white and squishy — inflated actually. He has a large pot belly and walks like a penguin. This robot is the legacy of Tadashi, his ultimate creation.

Besides Hiro and Baymax, the six include Go Go Tomago (Jamie Chung) who is a speed freak, Wasabi (Damon Wayons Jr.) who has terminal OCD and looks like he spends too much time in the gym, Honey Lemon (Genesis Rodriguez) who seems out of place in a robotics school because her expertise is in chemistry, and Fred (T. J. Miller) who just likes to hang out with the smart kids at SFIT.  Continue reading

Stellar Movie Fudges Science

picture of Harry KellerBy Harry Keller
Editor, Science Education

Interstellar is a great story with excellent acting, especially from Matthew McConaughey and Mackenzie Foy. For me, the three hours felt more like a normal two. Like the characters in the movie, I was asking where the time went.

In the not-to-distant future, maybe 20-30 years, the Earth is in real trouble. All efforts are now focused on food. Climate change has destroyed much of our ability to grow crops. National budgets have even eliminated defense spending.

InterstellarCooper, a former NASA test pilot, is now a farmer struggling against ever-increasing problems of drought and blight. He stumbles across strange gravity messages that direct him to the remnants of NASA run by Professor Brand (Michael Caine).

The film revolves around the relationship between Cooper and Murph (Foy and, later, Jessica Chasten, and, even later, Ellen Burstyn). This is the emotional center of the movie and the important love story. Oh, there’s another standard love story as well but one that definitely is not strongly promoted in the story.

Needless to say, there are adventures and sacrifices made, and the intrepid astronauts save the world through a combination of love, luck, and lots of fancy mental gymnastics.

If you’ve seen a trailer, you’ve seen a mountain-size ocean wave approaching people standing in calf-high water. These waves are continual on this odd planet and also are completely unexplained and irrational. What force could have moved so much water — over and over again? This is just the beginning of making this movie exciting while ignoring reality.  Continue reading

‘The Theory of Everything’ – A Hollywood Take on Science

picture of Harry KellerBy Harry Keller
Editor, Science Education

The new movie, The Theory of Everything, is about the life of Stephen Hawking from his graduation from Oxford to his becoming famous and then separating from his devoted wife of over a quarter century. Please, everyone, go to this movie. Why? Because it’s a good story, well acted and directed, and because you will be supporting the concept of telling the stories of scientists in movies. We must have more of this.

Stephen has a special resonance with me for strictly non-scientific reasons. We were born in the same year. We both entered prestigious colleges at the same age, 17, and went on to prestigious graduate schools for our doctorates. We were both married in the same year, he to Jane and I to Jayne. Of course, there are innumerable differences to balance these few coincidences. I majored in chemistry, he in physics. I have enjoyed rather good health overall. He is outrageously famous, while I labor in obscurity. And so it goes.

The Theory of EverythingBefore getting to the science, I’ll praise Eddie Redmayne for his uncanny portrayal of Stephen Hawking. From the early stumbling to the later crablike fingers and the difficulty in forming words, he nails Hawking in a manner that I never would have believed. Especially moving are the scenes in which he has the twinkle and slight smile showing Hawking’s personal joy at special moments and his puckish sense of humor.

This is a wonderful love story in which personal connection overcomes insurmountable odds. Jane (Wilde) Hawking’s (played by Felicity Jones) indomitable spirit lifts Stephen Hawking to the threshold of his greatness. We see this spirit and unwillingness to give up displayed several times in the movie. The very fact that Jane has three children, the last when Stephen is unable to move from his wheelchair speaks volumes about her. Ms. Jones brings a real sense of what the actual Mrs. Hawking must have felt to many of the scenes in the movie.  Continue reading

The ‘Fury’ of War Tanks

Editor, Science Education

The new Hollywood movie, FURY, focuses on tanks, their role, and tank crews in World War II. This 2-hour 14-minute film opens in theaters on Friday, 17 Oct. 2014. It stars Brad Pitt, a sure audience draw, playing the somewhat complex leader of the five-man crew of the FURY, a Sherman tank. If you go to this movie, watch Logan Lerman as Normal Ellison. He almost steals the show.

The movie starts in April 1945, near the end of the European part of World War II. VE (Victory in Europe) day is celebrated here as May 8, 1945. It’s spring, and everything is mud, mud, mud. American troops are in Germany by this time, and the famous Battle of the Bulge ended a few months earlier. German troops are now defending their homeland ferociously.

FURY, a Sherman tank.

FURY, a Sherman tank.

The main character of this movie truly is FURY, at least for me, and really did steal the show when I watched. The tank used in the filming was real, supplied by the Tank Museum in Bovington, England, a late-war Sherman with a 76mm gun. That’s the big gun on the turret. The inside shots were done in a specially created set that could open up in several directions for the different shots. The entire set was mounted on a gimbal that could move it for the inside shots where the tank was in motion. If you think that the inside of that tank looks really crowded, you should know that it was made 10% larger than the real thing.

Before discussing tanks in more detail, I should warn potential movie goers that this is a very violent movie with lots of grisly scenes, very grisly, and plenty of profane language in nearly every scene. Interestingly, there is no explicit sex.

For those who don’t mind the above, this is truly a riveting and tense movie. There’s little let up in the tension that begins with the first scene. I found it difficult to turn away from the screen even when the most horrific scenes took place. The characters are interesting but, except for Pitt (playing Wardaddy) and Lerman, they’re not plumbed deeply. Even Wardaddy, who says, “It’s my home” about the tank, never has this aspect explained, except implicitly. We are left to wonder if this attachment came about over time or from a single incident. We also are given no clue as to how he became fluent in German.

One more “character” in the movie is the entire FURY tank crew of five. The examination of the development of this team and its personality helps to make up for not looking more deeply into the individual characters because it’s the team and the tank that count in the end.

My favorite quote, again from Wardaddy, “Ideals are peaceful. History is violent,” sums up the movie. Get ready for a Hollywood ride.

Back to the tanks — we’re still using those old machines today. The first were used in World War I a century ago and were rather primitive. They were little more than mobile armored weapons and personnel protectors to move troops across the no-man’s land between trenches while withstanding the machine gun fire and easily trampling the extensive barbed wire fences for the following ground troops. The WWII tanks were much more powerful and versatile and formed the mainstay of many land operations. In the movie, we see quite a few German officers at the front on horseback. This contrast of horse and tank may be intended to suggest that tanks will soon go the way of the horse.

To have a better idea of what the past and present role of the tank is in warfare and what the future may bring, I interviewed David “Sting” Rae, a technical consultant for the movie. Mr. Rae sees a continuing role for tanks in the military. According to Mr. Rae, “The US Marines reinvented the role of the tank in Fallujah during the Iraq conflict where it proved almost decisive in breaking the will of the insurgents and allowing the infantry to take and hold ground.”  Continue reading

Real Aliens: What Will They Look Like?

picture of Harry KellerBy Harry Keller
Editor, Science Education

We live in a very large universe. By all accounts, it’s over 14 billion light-years to the edge from here. That’s nearly 10,000 billion billion miles. Our galaxy contains billions of stars. Our universe contains billions of galaxies. Somewhere out in those vast spaces, there must be, or have been, or will be another advanced civilization.

NASA's Spitzer Space Telescope has captured a new, infrared view of the choppy star-making cloud called M17, also known as the Omega Nebula or the Swan Nebula.

Unfortunately for those yearning to communicate with aliens and fortunately for those who fear alien contact, we are very unlikely — in the extreme — ever to communicate with an alien civilization. Our only real hope lies in violating Einstein’s laws of relativity, and so far they’re as solid as granite.

The vastness of space that makes the existence of aliens, at some time, likely also means that they will be too far away for any meaningful communication. If any are in our galactic neighborhood, they may have broadcast pictures of themselves just as we are doing every day with television, and we may intercept them if we can tease them out of the background noise of quasars, exploding stars, and so on.

Even an image of an intelligent, technologically advanced alien would add enormously to our knowledge of science. Speculation about what an alien would look like may seem like a waste of time, but it can help us if we ever do see one to recognize it.

The topic of what an alien, one with technology, with whom we could, in theory, someday communicate, will look like, act like, and so on has been in science fiction books and movies for many decades. Hollywood tends to reach for the extreme and depict aliens as very frightening. The movie, Alien, is a good example of that trend. Going back very far, there’s It Came from Outer Space.

The science suggests otherwise. Not that real aliens wouldn’t be, well, alien. The likelihood of them passing for one of us is rather remote. If you are teaching science, this concept can begin an excellent and engaging project investigating the possible parameters of alien beings capable of broadcasting images of the themselves. Before heading into the appearance of aliens, consider two separate issues that bear on this topic.  Continue reading

Dinosaurs Among Us?

picture of Harry KellerBy Harry Keller
Editor, Science Education

You may have noticed one of the many articles such as this one that cast doubt on the asteroid (or comet) strike that annihilated the dinosaurs. Oh, the asteroid did the job, they say, but it had some help.

Careful examination of North American fossil records strongly suggests that the dinosaur population was under stress from lower than usual herbivore diversity. What say?! There just weren’t as many plant-eating dinosaurs as usual, which means that dinner for the large meat-eaters was a bit harder to come by.

The Earth was undergoing extreme changes 66 million years ago when the great impact took place. Massive volcanic eruptions in what is now India were the result of a collision of the Indian and Asian continental plates. Climate was undergoing change. And dinosaur herbivore diversity was down.

The above was really no big deal. Dinosaurs had been around for well over 100 million years and had survived many environmental challenges. This was just another that would kill off lots of individuals and perhaps a few species. As a whole, the dinosaurs would come roaring back soon enough, however.  Continue reading

Martian Rhapsody: Chapter 2 – Rocks

Martian Rhapsody
by Harry E. Keller, PhD

CHAPTER 2
Rocks

The four hopeful settlers stare open-eyed at the vista that confronts them. Mars stares back, red-faced and malevolent. They discern nothing friendly or helpful in that stare. Some might see indifference, but they’d be wrong. If ever mankind faced evil, it is here in this impossibly alien and lifeless environment.

Even the dark, sharp-edged rocks strewn across the landscape with apparent reckless abandon seem infused with baleful intent, waiting patiently for countless eons for these soft Earthlings, waiting to cut them and trip them. The surface between the rocks is red, not the red of a poppy or even an Earth sunset, but an intense red that fills the land with emanations of harm. Despite the extreme thinness of the atmosphere, the strangely close horizon does not immediately and sharply turn to the black of space as on the Moon. The red dust of Mars hangs in the sparse air and softens the horizon just enough to give the appearance of red sand reaching up, an almost living thing.

As if sensing the planet’s personality, Chun speaks up, “We have to get that module back so we’re at full strength.”

“You bet!” responds Dawit excitedly, pumping his fist. He is undaunted by the landscape or the problem of the errant module.

“Sure,” says Aleka, “but first we have to put our habitat together.”

“Sorry,” says Chun as she moves into position.

“We all feel the same. All right, we’ve practiced this plenty of times,” says Aleka.

“Seems like thousands,” responds Dawit with a gesture none of the others can see because he’s inside.

“We don’t have all that long before our suits have to be recharged,” warns Balu.

“Right. Let’s rotate and connect,” says Aleka.

“Good thing that missing module connects at the end,” comments Chun.

“The rovers have done a nice job of clearing the site and putting the modules in place,” says Balu.

“I cannot wait to get a plan for the missing module,” comments Dawit over their intercom. Everything is an exciting adventure for Dawit.

Geography? T3G…ESRI in Education

VicSutton80By Vic Sutton

While at a recent workshop at the Redlands, CA, headquarters of the Environmental Science Research Institute (ESRI), I heard the most concise definition of geography yet: “What where? Why there? Why care?”

vic063014 1

My wife, Bonnie Bracey Sutton, had been accepted for a week-long workshop in ESRI’s T3G Institute. I traveled with her, thinking I was heading for a holiday in Southern California – maybe visit the beach and chill out in wine country.

No such luck. As soon as he saw me, Charlie Fitzpatrick said, “I’ll get you a badge.”

Charlie Fitzpatrick is the K-12 education manager at ESRI. Before joining ESRI in 1992, Charlie taught social studies in grades 7-12 for 15 years.

“T3G” is ESRI’s acronym for “teachers teaching teachers GIS.” So the goal of the workshop was to give a group of some 90 educators the knowledge and hands-on skills to be able to teach other colleagues how to use geographic information system information in their work.  Continue reading

GIS Helps School District Extend Facilities Management Beyond the Physical Plant

By Jim Baumann
Esri Writer

The Garland Independent School District (GISD) is located in north-central Texas, adjacent to Dallas. The district encompasses approximately 100 square miles and serves the Dallas suburb cities of Garland, Rowlett, and Sachse. With an enrollment of about 58,000 students, it is the thirteenth-largest school district in the state of Texas.

The GISD has a “district of choice” policy. This policy allows parents to choose where their children will attend school, based on established criteria for ethnic balance. Annually, the district has a one-month selection period for both secondary and elementary schools. Once the selection period ends, the district’s Student Services department begins the process of assigning students to campuses based on building capacity, grade-level capacity, and seat availability. Other criteria, including campus demographic data, are considered before making the final decision on school placement.

To help with student travel and support the district of choice policy, the district’s GIS (geographic information system) department developed a Flex application for distance routing. With this application, officials can determine the location of a student’s home and local schools within the immediate vicinity.

Converting AutoCAD Files to Geospatial Data

Garland maintains 7 high schools, 12 middle schools, 47 elementary schools, and 2 pre-K schools, as well as a number of administrative offices and special use facilities. Managing these facilities for compliance with governing standards, current use, past maintenance data, and potential renovation or remodeling projects became increasingly difficult, and it was decided that an automated system was needed to prepare plans and data for quick and easy access.

For several years, the district used Autodesk’s AutoCAD for facilities management. The district’s AutoCAD facilitator, Kelli Daughtry, was responsible for converting all paper drawings into AutoCAD and maintaining facility floor plans during the district’s $385 million bond program. Approximately four years ago, the facilities department began implementing a GIS to be used in conjunction with AutoCAD. The district retains all facility floor plans in AutoCAD while using GIS to provide easy access to site plans, floor plans, room numbers, and data referenced to them.  Continue reading

Mars: One-Way or Round-Trip?

[Note: This is part of Harry’s series on Mars, which began with “Mars One: Exciting Adventure or Hoax?” (4/8/13). As of 12/8/13, the discussion is still very active and has grown to 585 responses. Many of the comments are of article length, and the breadth and depth of information and participation make the discussion just as if not more valuable than the original article. The article has been tweeted 38 times and mentioned in 284 Facebook posts, and these figures are growing by the day -Editor.]

Mars is in the news again.1 And again. It seems that everyone is going crazy over Mars. The problems of getting to Mars are many and difficult, but that’s not stopping plenty of people from making plans and issuing press releases.

Skylark series

When I think back to my youth, I recall reading my first science fiction novel in a small local library after school in 1953. It was E. E. (Doc) Smith’s story of space travel, one of the Skylark series. At that time, no one had even put a tiny object into orbit.

A mere four years later, Sputnik I was launched, and the world entered the space age for real. Rockets to space were no longer science fiction. The next year, 1958, the United States put Explorer 1 in orbit. It weighed about 31 pounds. Dwight Eisenhower was president then. We were in the middle of the Cold War, and Nikita Kruschev was in charge of the Soviet Union. Both his picture and that of Sputnik I were on the cover of Time magazine the previous year. Indeed, if memory serves, he was the “Man of the Year.”Kruschev and Sputnik cover

No one knew how much payload could be put into space. No one knew the effects of prolonged weightlessness on people. The Van Allen radiation belts were discovered and verified by Explorer 1 and Explorer 3 in 1958, raising the issue of radiation in space.

Despite the lack of experience in putting satellites in orbit and the great uncertainties in putting a human in space, the United States not only put men into space but even put them on the Moon just eleven years later. ELEVEN YEARS! Starting from a tiny satellite in orbit, a lunar landing module weighing over 1,000 times as much and holding two people landed on the Moon in that short time.

Those who say that we can’t put people on Mars in 10-15 years don’t remember the magic decade of the 1960s. You have to watch out when you use that word, “can’t.” The Mars Direct program was proposed in the 1970s and was to have people on Mars by 2000. That didn’t happen, and technology has advanced enormously since then. It’s more possible today, and it’s still a very tall undertaking.  Continue reading
