The Scientist appreciates Art

December 30, 2008 · 3 Comments

A few days ago, I went to the Museum of Modern Art with some friends and had a fantabulous time! I’ve known these two since we were froshies in college. One majored in theatre, the other in art and marketing. So the scientist was among people of culture, and I love learning from them. (The poop jokes are great, too, but that’s a different story.)

First of all, if you are going to MoMA, and there’s a special exhibit, get tickets in advance! We couldn’t get into the special “Van Gogh and the Colors of the Night” exhibit since all the tickets were gone. It’s the holidays, what can you expect. That would have been especially fun with my art-geek friend* who knows quite a bit about Van Gogh. She did, however, take me on a breathtaking tour of the Impressionist movement in one wing, and the works of Jackson Pollock in another. I think I’m slowly starting to get the point of impressionism, in addition to just appreciating the aesthetics of the paintings. We briefly touched on pointillism, which of course got the lyrics to brainsbodyboth stuck in my head.

We moved onto Picasso and cubism, and how that influenced her favorite artist, Jackson Pollock. I can’t possibly go into the whole explanation here, as I will muck it up, but Pollock basically deconstructed objects in his paintings, and later removed objects all together, just working with the colors, the light vs. dark, and the paint. He even removed the artists brush strokes entirely from the art. Suddenly, as she taught me, paintings that before would have looked like silly, abstract paint blobs took on actual technique and beauty and movement. Something like Full Fathom Five really drew me in…

Oh, but you bet I found the little bit of astronomy that was there! Well, my buddy had to point it out to me with, “hey, there’s a galaxy or something over there.” There were pictures of the Orion Nebula in the photography section, so he was close.**

First, a drawing of the Orion Nebula, and boy can you see that seeing! The Third Earl of Rosse made this drawing with a six-foot reflector (really?!) in the 1840s.

Next is a black and white photograph from the 100-inch telescope at Mount Wilson Observatory. Long exposures mean more light collected, therefore a much better view than with the eye.

Below that was a vintage Sky and Telescope cover which I thought was freaking cool! This featured a color photograph of the Orion Nebula.

Finally, what fooled me into thinking it was a high quality digital photograph was actually a gorgeous color film print of the nebula taken in 1999 by David Malin.

In another section, the works of Jasper Johns were explored, specifically the trashed test versions of his prints which led to his final masterpieces, with all of their various themes and colors. Imagine being so revered that even your “junk” gets hung in a museum? Anyway, one work, labeled “Untitled,” included a galaxy that is some incarnations looks incredibly like M51.

Here is one version of the work:

and I encourage you to browse the many incarnations of this print from the museum.

And here, made with the 31-inch telescope at UVa’s Fan Mountain in the infrared, is M51:

Minus the companion, it looks strikingly similar! Maybe that’s just me, since my class took that photo for our final project. So I’m biased towards the Whirlpool. Which grand-design spiral do you think it looks like? Probably more importantly, how does it all fit together in the artist’s work? I was too busy going “ooo pretty galaxy” to really get that part.

So we’re trying to make a biannual thing out of this. In the summer, it was the American Museum of Natural History, this time it was MoMA. What NYC museum or cultural site should we city kids visit next?

* Yes, darling, you are a geek and I love you for it!
** Space Camp my ass! You are losing geek cred.

Plans, the Earth, and Skeptics

*pokes head from out of hiding*

Yes, I actually took a vacation this vacation, from most everything. I certainly needed it! I’m still running around the Northeast for a few more days, then it’s off to URSI for my first ever conference talk! Luckily, that’s over on the first day, so I can relax and enjoy the other scientific talks in the J session (radio astronomy!) and the sites around Boulder, CO. And, since lots of cool astronomy bloggers will be covering the American Astronomical Society meeting at that time, I’ll try and post fun and interesting updates from URSI right here!

A couple of cool things that caught my eye… Ian O’Neill blogs about human-caused climate change and how the Spanish conquistadors may have inadvertently contributed to the Little Ice Age. Really fascinating stuff! Also, Kimbo treats the general definition of skepticism and the skeptical movement in a very read-worthy post.

Tomorrow, it’s off to the city of brotherly love!

Skeptical Finances

December 26, 2008 · Leave a Comment

This week, while visiting family, I’m making my first trip to a financial planner. Grad students don’t make much, but science grad students do better than most, and I’m in that “quarter-life stage” where I should start thinking about doing something more useful with my little bit of money other than have it sitting in a savings account. The particular planner is a family friend, so I’m already going in with an implicit level of trust. However, I am very protective of my lil bit of cash, so I’ll be going in with lots of skepticism and risk aversion. That’s not being helped by the recent news of the Madoff scandal where many investors lost a lot of money in a veiled Ponzi scheme.

On this week’s eSkeptic, Stephen Greenspan, the guy who wrote the book on gullibility, explains how he was taken in by the Madoff scheme and lost some of his retirement fund. It’s well worth the read, and has me a little scared for my upcoming appointment! It’ll probably help me lean more towards conservative investing at this time. After all, I don’t plan on touching this money for many decades.

On a lighter note, learn how to avoid simple street scams with Michael Shermer in this two part video. My mother taught me that the card guys on the streets were con artists when I was very young, but I never learned how they did it!

Merry Christmas!

December 25, 2008 · 5 Comments

I know it’s so not-PC to say Christmas, especially around atheists, but as far as I’m concerned, I love my secular Christmas traditions! I’ve been saying Happy Holidays all season, since I prefer that greeting and to be all inclusive, but today, I’ll say it… Merry Christmas!

And, for those of you in the land of the Doctor, enjoy the Christmas special, you lucky kids. I’ll be, er, well, I’ll find *some* way to watch it over the next day or so… (Thanks, Mad Martha!)

Finally, since I grew up in the Catholic tradition, a little bit of INFALLIBILITY FAIL on this holy day, thanks to The Amateur Scientist.

Happy Earthrise Anniversary!

December 24, 2008 · Leave a Comment

40 years ago today, humans saw for the first time the Earth rise over the horizon of the Moon. The astronauts of Apollo 8, Frank Borman, Jim Lovell, and William Anders, because the first humans to escape Earth and actually orbit another body of the solar system. And they snapped this iconic picture:

An invitation…

December 23, 2008 · 2 Comments

I got this message in my YouTube inbox the other day, probably in response to my old and only video in response to the Blasphemy Challenge (no I won’t link to it, I hate myself on video!)

Just saying…

Jesus is Alpha and Omega the Begining and the End.
No one comes to the Father but through Jesus Christ.

Jesus died for our sins so that we can have eternal life through Him. He loves you and does not wish for you to go to hell but to have life. There are two places you can go after death and that is either Heaven or hell. Now in the bible it says hell has enlarged itself meaning more and more people are going to hell and its becoming bigger. Satan is going around and decieving many people in thinking there is no God or there is no heaven or hell. Do not believe satan, for he know his time is running out and he is trying to get as many souls as possible. There is a God and you don’t have to go to hell, all you have to do is accept Jesus as your personal Lord and Saviour. Its not hard at all and only takes a couple of seconds to become saved through Jesus. Jesus only ask of a small favor but, the hearts of men that make it so hard. Please repent, for Jesus is coming back sooner than you think to take back home His saints. But its up to you to choose wether you want to go back with Him and be in His loving care

God bless

At first, I thought I was going to be offended. But all I can see is someone who is really trying to… help. It wasn’t threatening, it wasn’t mean, it was an honest to goodness gesture. Normally, I am annoyed by proselytizing, but someone did take time out of their day to do a little something for me, to save me from a terrible fate that they believe may befall me. I can only say, thank you… but I think I’ll be alright.

Many theists, not this one in particular it seems, but some, get deeply offended when an atheist publicly declares his or her non-belief, even in a way that is not meant to convince others. Things like the “Don’t Believe in God?” ads (targeting other non-theists) or attempts at keeping church and state separate spark all kinds of outrage from some theists who wrongly feel that their rights are somehow being trampled. The so-called New Atheists are decried for writing books highly critical of religion, but of course, you don’t have to buy them. If more atheists were to actively proselytize like this fellow above, could you imagine the outrage then?

CVille Skeptics on Blogger!

December 23, 2008 · Leave a Comment

Like I mentioned earlier, I recently attended the first Charlottesville Skeptics MeetUp. It was lots of fun! People came with all kinds of backgrounds and ideas for the club, but all with the theme of being skeptical of the supernatural. It was quite comforting to be among like-minded folks, but people with such diverse stories!

One way I hope to foster discussion is with the CVille Skeptics blog. A shared blog has been a useful tool for the VAA, an easy, free way to keep in touch and keep current. I’ve started it off with instructions and some links on homeopathy, so check it out, and please join up if you are interested!

Sadly, I’ll be missing the second meeting, the Xmas Celebration! Hope it goes well and I’ll see ya at the next one…

Everyday Skepticism

December 21, 2008 · Leave a Comment

One of the most important ways to spread skeptical, critical thinking is by word of mouth. Discussing the paranormal and pseudo-science with your friends and family, pointing out local examples of credulous thinking, and honing your own critical thinking skills are all part of the fun of being a skeptic. Now, you can share your stories at Everyday Skeptic! Check out the first round of posts, which touch topics such as 9/11 truthers, tarot cards, and credulous news reporting. Maybe you have a story or two to share!

I’m back in NYC for the holidays! I know what I’ll be doing to relax… reading the Carnival of Space #84 at Next Big Future.

And introducing everyone to tree lobsters.

Geomagnetic Reversal

December 18, 2008 · 4 Comments

I received a text message from a family member yesterday asking “Did you ever hear of the polar shift?” Intrigued, I replied that I did, and guessing where this was going, added that, no, we were not in for a doomsday event in the near future. Today, I was able to follow up with a more detailed email response to ease her and her co-workers’ fears. What follows is most of that email!

By pole shift, that usually means that the rotation of a planet has changed drastically, causing all kinds of havoc on geology and weather. The Earth’s rotation is very stable and may only wander by less than a degree over a million years, so that’s not worry. It would take large impact, like ones that the planets suffered 5 billion years ago, to really knock a planet around.

I’m going to assume that we’re talking specifically about something called geomagnetic pole reversal, meaning that the poles of the Earth’s magnetic field will actually reverse polarity. So, to start we need to know that the Earth has a magnetic field, often pictured to look like a bar magnet, that is created by rotating, liquid metal in the earth’s core. It is why our compasses point north and it protects Earth from lots of harmful particles, called cosmic rays, that come from the Sun and elsewhere.


(From http://oceanexplorer.noaa.gov/explorations/05galapagos/logs/dec22/media/magfield_600.html)

Despite the simplistic picture above, the magnetic field strength can increase and decrease, and the poles can actually completely flip! In fact, the magnetic field of our sun flips every 11 years or so, which is tied to the solar cycle of increasing and decreasing solar activity. Since the sun is a ball of gas that doesn’t rotate uniformly, it makes sense that the magnetic field will get twisted and do funny things. The Earth’s is much more stable, but not completely so. It has been shown by the direction in which magnetic materials in ancient rocks point that the Earth’s magnetic field has flipped many time in the past!


(From http://blue.utb.edu/paullgj/physci1417/Lectures/Magnetic_Reversals.JPG)

This isn’t a sudden change, however, and takes thousands of years, over which time the magnetic field strength may decrease. Current work shows that the magnetic field is decreasing and that we may be due for a polarity reversal… but only over the next couple of thousand years.

What will happen to us when this occurs? Well, probably nothing. In fact, our human-like ancestors homo erectus lived through the last polarity reversal with no signs that the population suffered any damage. In fact, there has never been a strong link to polarity reversal and any large extinction event. What is most vulnerable is our technology. During a period when the magnetic field is weak (or solar activity unusually strong), solar storms can knock out satellites, disrupt radio communications, or even cause large power outages. However, since these changes will be gradual, I suspect that our technology will evolve to cope with the changing environment. Even now, scientists are working on early-warning systems for solar flares, such that important satellites and even astronauts can hunker down and prepare for the blast of high energy particles. Of course, I’m going to pimp one such effort that is going on in my own lab with the Solar Radio Burst Monitor.

Why are we hearing all about this now? Well it’s the 2012 doomsday nonsense that is quickly selling books and now a movie. This is tied to something called the Mayan long count calendar, which is supposedly due to expire in 2012, signalling the end of the world. People have come up with all kinds of pseudo-scientific scenarios on how the world will end, and they are not entirely based on fact and in fact quite easy to dissect. If you are interested, I could get into it more, or you can read a fascinating series of articles by Ian O’Neill on this at Universe Today.

But really, if the Earth was due for some catastrophic calamity in three years, astronomers would be screaming at the top of their lungs to do something about it! And if there was nothing we could do about it, well we’d all quit our jobs and live out the rest of humanity’s span on some tropical island sipping strawberry margaritas. Or maybe that’s just me.
