Geeks You Should Know: Rene Descartes

With that long hair and facial hair, Descartes is already half way to a hipster.

With that long hair and facial hair, Descartes is already halfway to a hipster.

Rene Descartes was born March 31, 1596 in France. In 1606 he began attending Jesuit College in La Fleche and studied there until 1614. His curriculum included a study of the classics, as well as current understandings of physics, metaphysics and math. From 1616 to 1618 he studied law at Poitiers, but he never made use of his law education. Shortly after graduating he became a gentleman soldier and continued to serve until 1622. Descartes started to develop his theories during his time as a soldier but didn’t given them his full attention until after his return to France. In 1637 Descartes published Discourse on the Method of Rightly Conducting the Reason and Seeking Truth in the Sciences, the work he is most well known for. Descartes died in 1650 in Sweden, where he was the personal philosophy tutor for Queen Christina.

Why we care:

Descartes is most famous for his statement “Cogito ergo sum” meaning “I think, therefore I am”. This frequently gets misunderstood to be, “I exist because I think.” This is an obvious problem given how many people that we all know who don’t think and yet still exist. What Rene was actually getting at is the idea that we exist because we believe we exist.  He brought a more scientific approach to philosophy.  The idea of leaving all accepted notions and preconceptions behind and starting from a clean slate was revolutionary. This approach earned Descartes a place as the father of modern philosophy.

What Descartes is less known for, though it may be far more important, is his introduction of analytical geometry. Anyone who has taken a high school algebra course is more than familiar with the standard x-y coordinate system. Here in the U.S. we refer to this as a Cartesian coordinate system, but it is in fact an invention of Descartes (Cartesian comes from the Latin name Descartes used, Cartesuis). This is one of the most fundamental pieces of modern mathematics and it exists thanks to Descartes.

In addition to the x-y axis, he also gave us laws of refraction, explanations for rainbows, and an account of the formation of the solar system, though he suppressed much of this theory due to the pope’s attacks on Galileo. Descartes even developed laws of motion which were a precursor to Newton’s Laws, although they failed to incorporate vector forces. Descartes managed to impact multiple branches of thought and science and his work has had a lasting impact on the world, making him a Geek to Know.

A city north of London looks to be the first city to roll out self driving cars. Minton Keynes is starting its program with 100 cars that will take passengers to various destinations for a minimal fee of $3. The program will start in 2015 with a full roll out by 2017.

Even with speed limited to 12 mph, this is still a huge leap foward. I’d love to know why we in the US can’t seem to get ourselves moving on this.

So often women in the sciences don’t get proper recognition for the important contributions they make in their chosen fields. One New York exhibit is working to change that. The exhibit highlights the work of thirty two different women, some as famous as Marie Curie and Florence Nightingale, and others who are less well known, though just as important. The exhibit also provides interesting little tidbits about their lives, such as that Marie Curie drove to the Western Front in WWI to x-ray wounded soldiers.

In male dominated fields, like the sciences, it’s often too easy to forget that there have been women proving they are equally capable of ground breaking discoveries. The exhibit runs through Nov. 23.

For those of us who are frequent internet shoppers, one of the biggest fears is that our awesome new acquisition will be stolen right off the door step while we’re at work. Now with the Doorbot, you can go to work with peace of mine. When your doorbell rings, the Doorbot lets you know via an app for your smartphone and then allows you to see who is at your door. If combined with a Lockitron lock, you can unlock your door, allow the delivery man to place the package safely inside your house, and then lock the door behind him.

Now hopefully nobody steals the package that delivers the Doorbot.

Of course, on everyone’s mind this week is Super Typhoon Haiyan. How did this storm get to be so massive and destructive? It turns out that Haiyan is the fifth storm of this magnitude in the Pacific this year. For comparison, it has been six years since there was a storm this bad in the Atlantic. Haiyan and the other storms like it are due to a combination of three factors:  higher surface water temperature, higher subsurface water temperate, and low wind sheer. These three allow large storms to continue to grow in size while also moving as one.

While the science of these storms is quite fascinating, we can’t forget the human toll. Please donate to the Red Cross and help these people in their time of need.

Review: Godzilla (1954)

1954’s Gojira is a piece of film history.  For those of you scratching your heads, Gojira is more commonly known in the United States as Godzilla—everyone’s favorite foam rubber monster. When most people think of Godzilla, they think of men in sketchy looking, foam rubber suits fighting each other in a model town, crushing everything in their process (poor Tokyo). This stereotype might be true for some of the later movies, but the original Godzilla is much more complex than that. Not only is it a classic B movie, but it also provides us with some valuable insight into post war Japanese culture.

The most important thing to realize about Godzilla is that there is a plot, despite popular belief to the contrary. In fact, not only is there a plot, but it’s a pretty good one. The film starts off with the mysterious sinking of a fishing vessel; a flash of light from under the water and the ship is engulfed in flames and sinking. Shortly thereafter another boat shows up to investigate the scene of the first sinking and it too is destroyed in spectacular fashion. While the Japanese Coast Guard investigates, a fishing village on the island of Odo is ravaged by what is first thought to be a storm, though there are reports of a giant monster that caused the damage. The Japanese government sends a scientific team to investigate, and they discover enormous, radioactive footprints throughout the village. Between the radiation and the discovery of a trilobite (a small creature thought to be extinct millions of years ago), the scientific team concludes that the creature must be from the Jurassic period.  Soon after Godzilla himself is sighted on the island.

Mmmmm, train...nom nom nom.

Mmmmm, train…nom nom nom.

The Japanese Coast Guard decides that Godzilla is too much of a threat and must be destroyed and attempts to do so with depth charges.  Of course this goes poorly for them and only drives Godzilla to attack Tokyo harbor.  Eventually Godzilla is driven off, but not before turning Tokyo into a flaming ruin.  In a final act of desperation, Japanese scientists release the Oxygen Destroyer into the water of Tokyo harbor, killing all living things in the harbor, including Godzilla.

To begin, the incidents involving the fishing vessels mirror a real life incident in which the crew of a Japanese fishing vessel were exposed to extreme radiation from an American underwater Hydrogen bomb test. While film makers caught considerable flack from critics and the public for this parallel, it tapped into the Japanese cultural mindset. Godzilla was released only nine years after the end of WWII and the horrors of the nuclear bombs were still fresh in everyone’s minds. In the 1950’s, there was still a lot that was unknown about the effects of radiation, but the fear of radiation is still a very real concern for the Japanese even today.

When the senior scientist presents his results to the Japanese government he immediately blames the H-bomb tests not only for disturbing Godzilla, but also for causing his mutation in the first place.  The Japanese government wants to destroy Godzilla, but the scientists want to study him, especially his resistance to high level radiation, in an implicit effort to better treat those who’d been exposed to radiation.

Godzilla’s attack of Tokyo harbor leaves the entire city in ruins, between his crushing things under foot and breathing fire all over the city. The scenes of a devastated city, filled with rubble and flames must have also hit home with Japanese audiences who remembered living through the firebombing of their cities. The fact that a monster movie like this can so directly tap into the pulse of Japanese society speaks volumes about its quality.

There are many things I love about Godzilla; chief among these is the miniature work. Well before the advent of computer generated special effects, the only options available to film makers were to film full-sized events (like Buster Keaton in The General) or use miniatures. Full sized effects are often one shot attempts, expensive and very limited in scope. Miniatures, on the other hand, allow for a world of options, can be repeated if the shot isn’t to the directors liking and are reasonably inexpensive. The real trouble with miniature work is that, done wrong, they can look terrible. Thankfully, the work in Godzilla is surprisingly good. Most of the work was masterfully done, with incredible attention to detail. There were also several occasions where the film makers blended miniature work with live actors.  Several scenes of destruction showed live actors on a set which was then destroyed (in miniature) after a quick cut.  It is almost impossible to tell the difference between several of these sets and their miniature counterparts.  There is only one time the miniature work disappoints me and that is when jets finally chase off Godzilla. The jets themselves look like cheap models made from balsa wood and the wires attached to them and the rockets they fire are very visible.

I also thoroughly enjoyed the science aspects of the film. From the use of actual Geiger-Muller Counters, to the discovery of the trilobite in the foot print, there is factually accurate science all over the film. My favorite reference was to the discovery of Strontium-90 in the footprint, which—after a few minutes of Google searches—I discovered is actually an isotope found several weeks after the detonation of an atomic weapon.

Even the ending of the movie is dependent on science, although that science is unfortunately utter garbage. The idea of an Oxygen Destroyer is completely ridiculous though it does serve a purpose, aside from ridding th0e world of Godzilla. The Oxygen Destroyer is a weapon that is even more dangerous than the atomic bomb and it isn’t used until there are no other options left and even then the creator dies with his creation to ensure that it can never be used again. Given what they experienced as a culture, it’s no surprise that the Japanese have this feeling towards a weapon of mass destruction and the willingness of a scientist to sacrifice himself in order to prevent it from being used by anyone ever again.

This man was willing to die to prevent another Hiroshima.

Even though it is a monster movie, Godzilla is definitely worth checking out. If you need more proof of this movie’s excellence, just look to the fact that the year it was released if won the Japanese Movie Association award for Best Special Effects and was nominated for Best Picture, losing to Kurasawa’s Seven Samurai. Without a doubt this film warrants five Death Stars.

Winning Science!

I am all for the exploration of space.  Being a lifelong Star Trek fan I feel that we are actually way behind the times when it comes to advancing our knowledge of the universe.  Here are a couple stories about some of the things that NASA is doing to help move the ball forward.

Curiosity probe is going on a trek 10 times longer than its ever gone before. But before it leaves on its journey, Curiosity stopped for a little impromptu art.  Neil Armstrong left a footprint, and a flag, and said some inspiring words when he landed on the moon.  Guess standards have fallen a bit.

Also, NASA’s Opportunity rover finds water on Mars. Personally, I think I’ll run it through a filter before I take a sip.
