Star Trek and the Start of the Semester

Nearly a month since my last post due to two things: I haven’t seen a movie in a theater in that time, and it has been an insanely busy time at work. I am teaching a new course and have had a number of review writing and other deadlines. On the research front, work continues on the Microgravity Experiment on Dust Environments in Astrophysics, a somewhat awkward name that allows us to use the more convenient acronym MEDEA. I’ve created a Facebook group: The Colwell Research Group. This will have images, data, video, and other updates on my own research. Please look us up and “like” us if you’d like to follow along with our research activities.

On the Cassini front, we are now in the Cassini Solstice Mission: the second and final extension of the mission. However, this extension exceeds both the prime and first extension in total length, with a finale around lunch time (1:00 p.m. Eastern) on Friday September 15, 2017 as Cassini dives into Saturn’s atmosphere. For the next year and a half, though, Cassini is in Saturn’s equatorial plane meaning there won’t be much in the way of observations of the rings for a while.

Star Trek: I used to be an avid player and tournament director of the Star Trek Customizable Card Game. For a variety of reasons, including embezzlement at the company that made the game, it eventually stopped production. Recently I learned that a group including some of the game’s designers is keeping it alive and that there is a small but vibrant group of players here in Orlando. It is a great hobby and is now once again sopping up spare minutes of my time (and giving my head a much-needed diversion from work in the process).

My Erdös-Bacon Number

My Erdös-Bacon number is 6. This is the sum of my Erdös number (4), which measures the number of degrees of separation I have, through authorship of academic papers, from prolific Hungarian mathematician Paul Erdös, and my Bacon number (2), which measures the number of degrees of separation I have, through movie roles, from American actor Kevin Bacon. My Bacon number is low courtesy of my role in the movie Deep Impact which features a large cast of many veteran actors. My connection to Bacon (or at least the first one I found) is via Maximilian Schell, who was in Telling Lies in America with Kevin Bacon. So Schell has a Bacon number of 1, and since I was in Deep Impact with Schell, I have a Bacon number of 2.

Figuring out my Erdös number required a bit more sleuthing, but was greatly aided by this website, provided by the American Mathematical Society, which will provide the Erdös number of any author in the database of math papers. The difficulty is that I am not in their database. So I made some guesses as to co-authors of mine who might be in their database. The first good hit was Frank Spahn, a dynamicist friend and colleague at the University of Potsdam who has an Erdös number of 5, giving me E=6 and and E-B number of 8. When I thought about other possible connections, though, I hit on Jeff Scargle, a mathematically inclined planetary scientist at NASA’s Ames Research Center. While I have not authored a paper with Jeff Scargle, I have with his Ames colleague, Jeff Cuzzi. Scargle is in the database with an Erdös number of 2, giving Cuzzi an Erdös number of 3, and me E=4.

Why does anyone care about these numbers? Well, most don’t. The idea of degrees of separation has been around for some time, and a game was created around the idea of finding the number of acting degrees of separation from Kevin Bacon. These calculations of degrees of separation are a way to quantify the “small world phenomenon” that posits that the human population is a network of connections where the number of links between any two individuals is small. The world of mathematical journals is sufficiently different, that even having an Erdös number and a Bacon number is fairly unusual. And since the whole connection concept is essentially a mathematical model, it seems fitting to have a small world number based on a mathematician. Paul Erdös wrote well over 1000 scholarly articles, so mathematicians used him as a root for degrees of separation in that particular world. My E-B number of 6 puts me one behind Brian Greene (5) and one better than Stephen Hawking and tied with Richard Feynman.

Avatar v. The Hurt Locker

I would not be surprised to see the experiment of an expanded list of Best Picture Oscar nominees come to a quick end. The Academy of Motion Picture Arts and Sciences, a body of about 6000 industry professionals that awards the famous statuettes, doubled the number of Best Picture nominees to 10 this year while leaving all other categories unchanged. The motivation, ironically, was to include blockbuster movies that are frequently pushed aside by those pesky unknown independent and low-budget movies the Academy voters tend to favor. Of course, the Academy was not really worried about blockbuster movies not getting enough attention. Their concern was declining ratings for the annual awards broadcast. Viewers are understandably less excited about awards going to movies they have never heard of, let alone seen. By nominating 10 movies for Best Picture the Academy reasoned that popular movies that would otherwise be snubbed by the hoity-toity Oscars would be included in the celebration and draw more people to watch the awards show. This seems to have worked: this year’s show was the most-watched Oscar-cast since 2005.

The extended list of nominees did include three popular movies that would otherwise have been overlooked: Up, The Blind Side, and District 9. Avatar, the all-time blockbuster, was nominated, but it would have been a lock to be nominated even in the original 5-picture format. And Up, an animated movie, was nominated for best animated picture, so its inclusion in the Best Picture nominee list did not really expand things. Of the remaining 6 Best Picture nominees, Inglourious Basterds cracked the $100 million mark, and Up in the Air had a respectable $83 million.

But Avatar is the elephant in the room. Visually groundbreaking and tremendous fun to watch, Avatar was the movie of 2009. While The Hurt Locker is a great movie, Avatar is a landmark movie and one that, like The Wizard of Oz, will be talked about for years, likely decades to come. By not giving Avatar the Best Picture Oscar, the Academy risks making itself seem even more elitist and disconnected from moviegoers. While we’ll never know, I believe that had their been only 5 nominees, as in years past, Avatar would have won. The reason is that to accommodate the expanded list of nominees, the Academy changed the voting procedure for Best Picture. Rather than voters simply selecting the one movie they would like to win, for Best Picture they ranked movies from 1 to 10. If less than 50% of the voters ranked any one movie at the top, the lowest ranking movie is eliminated, and the 2nd ranked movie on all the ballots that had the eliminated movie ranked first would then get tallied in a second round of voting. The process of eliminating from the bottom up continues until one movie is the top selection of more than 50% of the ballots.

The reason this might have tilted things away from Avatar is that even if a plurality of voters chose Avatar to win Best Picture (the only requirement necessary in years past), if a significant fraction of the other voters placed Avatar far down the list while The Hurt Locker ranked at number 2 or near the top of almost everyone’s list, The Hurt Locker would eventually come out on top. I think voters that did not want Avatar to win, really didn’t want it to win and so could effectively cast an anti-Avatar vote by ranking it low on their list. Meanwhile, nobody who saw The Hurt Locker would be actively against it winning. It’s a great, tense movie, and certainly in no way is it undeserving of winning Best Picture. Avatar, on the other hand, while in some ways a cliche, is, it’s fair to say, a film for the ages. The Academy is certainly not against giving Best Picture awards to big blockbusters. See Titanic (deserving), and The Lord of the Rings: The Return of the King (not so much). My guess: Avatar had a plurality of first-place votes on the first round of ballot-counting as well as a significant number of low-ranking votes from the stereotypical grumpy Academy member who was resentful of its success, irritated by its corny message, or determined to reward the excellent lesser known movies on the ballot. Avatar, after all, already has its billions, the thinking might have gone. Meanwhile, The Hurt Locker probably ranked in the top three on almost every ballot. So this year’s Best Picture winner might have been more of a consensus winner, while in years past a movie could theoretically have won with merely 20% plus 1 vote.

The Great Faith Debate

Tonight, “new atheist” Christopher Hitchens and “new apologist” Dinesh D’Souza engaged in a debate on religion at the UCF arena. According to the moderator, it was the largest crowd for such a debate to date. (I would guess about 4000-5000 people were there.) On points, D’Souza out-debated Hitchens who appeared sweaty, frequently spoke so low and rapidly to be incomprehensible, and did not take advantage of many easy rebuttals of D’Souza’s arguments. D’Souza spoke clearly and with more conviction. While his arguments were mostly tired and not convincing of anything in particular, they enthralled the majority of the audience.

The questions the debaters were supposed to address were: “What about God?”, “What about Christianity and other religions?”, and “What about science and reason?” The best point D’Souza made, in my opinion, was that Christianity is qualitatively different than other religions because it involves the descent of God to the level of man in the form of Jesus, where other religions involve the aspiration of humans to ascend to the level of God. Hitchens ignored this, probably because it is irrelevant to the question of whether or not Christianity makes any sense, and also does nothing to refute Hitchens’ argument that Christianity, like other religions, imposes odious rules on behavior (for example, we cannot choose who we love, but must love Jesus (and our neighbor) or face damnation). Another of Hitchens’ arguments on the evils of Christianity is that, like other religions, it is invoked as an excuse for a long litany of horrible deeds. I think my principle difference with Hitchens is that I think for the most part, people do evil because they are evil, not because they are religious. Frequently religion is a handy tool for evil-doers, but it is not a prerequisite.

D’Souza’s most dramatic proclamations were repeated claims that the universe, like the play Hamlet, has a plot and a design and therefore must have an author. Hitchens, in my view, failed to call him on this, going on a tangent about how one determines the identity of the author rather than refuting the ridiculous claim that the universe has a plot and a design. D’Souza also repeatedly stated that the universe is “fine-tuned” for the existence of humans, implying that there is not only a creator, but that the creator cares about our existence. Hitchens also let these easily rebutted claims go unchallenged. The fine-tuning D’Souza refers to is that if the fundamental constants of the universe are changed by small amounts, things like stars would not be possible. Any universe that ever existed or exists with those different constants therefore could not have any beings in it remarking that there must not be a creator because if there were it would not have made a universe with such lame fundamental constants. We only can exist in a universe like the one we do exist in. Astronomers have now detected hundreds of planets in our corner of the galaxy, beyond the handful in our only solar system. Of these, only one apparently is “fine-tuned” to allow life to exist. D’Souza would apparently conclude God must exist to create such a fine-tuned planet. But we can’t exist on any of the other planets. Out of hundreds (known so far), all planets but one are not fine-tuned for life. If a designer fine-tuned the universe for homo sapiens, it was a remarkably inefficient job: our little planet is a vanishingly small fraction of a universe that is, for the most part, completely inhospitable and also beyond our reach. Our primitive understanding of cosmology does not preclude (and in fact supports) an analogous situation for the universe: many may exist, and we inhabit one in which it is possible for life to exist.

But the most remarkable unchallenged argument of D’Souza was his supposed rebuttal of the “God of the gaps” argument (one not raised by Hitchens). To paraphrase D’Souza, atheists and scientists have unscientifically dismissed various discrepancies in the predictions of scientific theories, expecting them to be resolved by minor improvements in the theories. Two specific examples he gave were the failure of the Ptolemaic model of the motion of planets to accurately predict their positions, and the failure of Newtonian dynamics to explain the precession of Mercury’s orbit. In both cases, he stated with great import, a revolutionary change in the relevant scientific theories was needed to explain the discrepancies, not a small incremental change. So – the scientific method successfully explained theses discrepancies. New theories were developed that worked better than the previous ones. That’s how science is supposed to work. How exactly is a physics-based, scientific explanation for the universe and the triumph of the evidence-based scientific method supposed to be refuting a rational model of the world and supporting a faith-based one?

An Imagined Conversation with a Moon Conspiracist

With the 40th anniversary of Apollo 11 I have heard more than I care about the delusional segment of the public that insists we did not go to the Moon. Only for my peace of mind, I have imagined a conversation with a Moon landing conspiracist where I ask him if he believes people have been to Antarctica. (My satisfaction in this imaginary conversation depends on him saying “yes,” but the beauty of me imagining this conversation is that I do, in fact, get to decide what the other person says.) So he says “Yes, of course!” to which I reply, “Why?”. Well, you can imagine the responses to this as well as I can, because presumably you also believe people have been to Antarctica, and unless you have personally been there yourself (and I know some of you have), all your reasons for believing people have been to Antarctica are the same as the reasons for believing people have been to the Moon: we have seen pictures of people there; we have talked to people who have been there; we have seen things that were brought back from there; we have seen the machines that take people there. Qualitatively, (unless, again, you have been there yourself), there is no difference in the evidence for people going to the Moon and the evidence for people going to Antarctica. My imaginary debater can then only fall back on the idea that going to the Moon is implausibly hard, to which I wonder if he believes that I can store thousands of books, pictures, songs, and movies on a device the size of a matchbook and why he thinks that is easier that sending a rocket to the Moon. In my imagination, my foe is crushed on the withering force of my logic. In reality, of course, there is just no arguing with some people.

John Lennon and Jesus

I’ve always been mystified by the outrage provoked by John Lennon’s infamous statement that the Beatles would outdraw Jesus. Now the Vatican has forgiven the statement, though it seems clear that Lennon’s statement was never a comment about Jesus or religion, but about pop culture. It is also clear that it was a hyperbole, meant to pick the most extreme example possible to express his amazement at how fanatical Beatles fans were in the mid-60′s.

Ethical Treatment of Animals

Humans have made significant progress in applying basic concepts of human rights to all people (though there is still much that needs to be done in guaranteeing rights for women in much of the world). The ethical treatment of animals still has a long way to go, but there are many groups that have managed to improve the living conditions of farm animals. Now a landmark decision may be near in Spain that grants our closest animal relatives the right to life, liberty, and, if not the pursuit of happiness, at least the right not to be tortured. That puts them ahead of humans deemed by our administration to be enemy combatants.

Evolution in Florida

Florida’s State Board of Education voted (4-3!) this week to include evolution (for the first time!) in the science curriculum of public schools. (Previously the concepts of evolution were taught in Florida, but the curriculum referred only to things such as “change over time”. My own recollecton of Honors Biology in a Florida High School are that our class had a debate on the topic of evolution. I was one of three or four on the side arguing in support of evolution, and the opposing group argued for Biblical creation. I do not recall any instruction on the matter in class at all.) The new standards were apparently headed for defeat until a so-called compromise was reached by inserting the words “the scientific theory of” before the word “evolution”. This concisely illustrates the anti-evolution advocates’ lack of understanding not only of evolution but also of what “scientific theory” means.

American Gangster

Starting as a somewhat scattered and murky movie tracking the rise of Harlem drug boss Frank Lucas, American Gangster hits its stride halfway through once cop Richie Roberts (Russell Crowe) is given a special task force to tackle the rampant New York drug problem. The story of Roberts’ difficulties in his private life, involving a lengthy divorce proceeding and his night law-school studies, is more distracting than anything else. It also makes Crowe’s decision to portray Roberts with an awkward duck-like stride and nervous habits jar with the depiction of his character as a rampant womanizer. Denzel Washington brings Lucas to life as a chilling but somehow like-able killer that you nevertheless really want to see brought down. Stephen Zaillian’s screenplay was inspired by this New York Magazine article about Lucas. I recommend seeing the movie before reading the article, as I did. The latter half of the movie, especially, is gripping story-telling. It is fascinating to see the scale of the dope operation that Lucas ran in Harlem and to learn that his was but one of many. I found myself simultaneously hoping desperately for him to be captured, but also for him to come out of it all okay somehow.

There is more interesting information on Lucas here that provides a bit more dose of reality to some of Lucas’s claims as well as the dramatic depictions of events in the movie.
