Bill Bryson - A short history of nearly everything (Kilala.nl (Cailin Coilleach)) by Cailin Coilleach

For my birthday, my sister got me one of the awesomest books I've read in the past few years: A short history of nearly everything by Bill Bryson. It'd been on my wishlist for quite a while now thanks to the folks at Ars and now it's finally mine :D

If you've ever been even remotely interested in physics, astronomy, chemistry, the earth, the human race or our weird scientists, then this is the book for you! Bill takes a lighthearted look at how -everything- came into existance. How did the universe form? What -is- the universe? What is gravity? How does it work? Why does it work? And the best part is that all of this is done in a rather humorous fashion. Bill not only focuses on the science itself, but also on the scientists themselves who can be -really- odd at times.

Aside from reading the book for the entertainment value I actually learn a lot as well. For example, there's the fact that atoms and such really aren't solid objects and that thus solidity itself (of objects) is merely an illusion. To quote the book:

When two objects come together in the real world - billiard balls are most often used for illustration - they don't actually strike each other. 'Rather,' as Timothy Ferris explains, 'the negatively charged fields of the two balls repel each other ... [W]ere it not for their electrical charges they could, like galaxies, pass right through each other unscathed.' when you sit in a chair, you are not actually sitting there, but levitating above it at a height of one angstrom (a hundred millionth of a centimetre), your electrons and its electrons implacably opposed to any closer intimacy.

More unexpected calls (Punkadyne Labs (Punkwalrus))

I wanted to clean my house tonight because I have guests coming over. I didn't get to, and here's why:

I got a phone call.

Last time I got a phone call this random, it was to pick up a friend from the police station a few months ago. I won't go into that, suffice to say it was based on a misunderstanding that got out of hand. This call was from my friend Jason, whom I will name, because he was stranded in Vienna for several reasons.

First, he was flying in to give a dissertation on the NSF to get funding for astronomers (he is an astronomer, see). But after his presentation, he found that the hotel had overbooked, and he couldn't get one. No worries, he's got local family. But his mother, who lives in Lynchburg now, was unable to pick him up because she was sick. She had the key to her younger brother's apartment to let Jason in, but said Jason could just come over. But Jason's uncle didn't show up. Jason called him, went to his house and knocked the door, but no answer. So then he called me.

HALP!

We were more than happy to pick him up and give him a place to stay. We took him out to dinner, and spent some time catching up. Normally, we have a 1-year gap between visits, but this was only 3 months. We discussed the usual stuff; his classes, Daytona (where he lives), the space program, telescope time, what he was doing in DC, and various tech subjects. I really like Jason a lot, and I realized he's been my friend now for 22 years! Amazing. Our friendship is old enough to drink.

Later, he got ahold of his uncle, and so he didn't have to stay with us after all. Bummer. But at least he gets a bed and doesn't have to do the couch thing. Posted in: astronomy , jason , phone calls

Man, what a weekend (Punkadyne Labs (Punkwalrus))

So, a lot happened this weekend. Most have to be behind LJ-Cuts because the contain all sorts of nude photos, impossible geometry, and the rest of the Zapruder film the CIA cut out (the parts with Bigfoot).

Overall, I give this a B, sliding towards a B minus. I saw this thanks to [info]takayla, who gave this as a Christmas present to myself and CR.

There was a lot they did right. I saw the performance at the National Theater, and a majority of the cast was excellent. The musical numbers were stunning for such a small venue, the props were very clever, there was humor both fresh and classic, and enough new material mixed with old that makes seeing this worth it.

For those who have not seen it, it's about 50% of the story of "Monty Python and the Holy Grail." The plot is similar where King Arthur makes a quest for the Holy Grail, as deemed by God, and picks up his knights along the way. Some of the scenes from the movie are in there, albeit altered somewhat. The rest is completely different (ha ha). There's a new main character, "The Lady of the Lake" and her "Laker Girls." They break the fourth wall a lot; for instance there's a musical number where the Lady of the Lake is upset she hasn't been in Act II until just now. The orchestra gets cut off a lot. Mentioning how expensive certain sets were, and how the wires holding up Tim the Enchanter were "impressive and completely undetectable." There are a lot of local DC and current event jokes, so I assume that the DC cast had some flexibility with this.

The cast I saw were, for the most part, very good. The one glaring exception was the man playing Arthur, who dressed like Tim Curry, sounded like Tim Curry, but performed his part with such a rehearsed process, you'd think he was tired of the part and just wanted the evening over with, so he switched to autopilot. His lines lacked a punctual panache, which is essential for comedy. He rambled through his parts with emphasis on the last sentence only, which was awkward. In contrast, the person who played Sir Robin was excellent, and the Lady of the Lake (who was a substituted understudy that evening) was perfect. The rest of the cast supported well, and I am not sure they could have done any better because their parts were fairly unimportant to the main story.

There were certain scenes where I went, "How are they going to pull this off? How will they show the black knight getting ALL his limbs cut off? Oh, very clever!" use of props spanning the passing of time were particularly creative.

A few times the scenes suddenly skewed from the scenes in the movie. The French taunting, for instance, ends with a dance number by every French stereotype they could dress someone up in. The Knight's who No Longer Say "Ni" said a few verses from "My Humps," and demanded King Arthur put on a Broadway production (but can't, because "they don't have any Jews," which led to a VERY impressive musical number that spoofed "Fiddler on the Roof").

Those who are rabid quoters of the movie will cringe when the lines change ever so slightly. But will laugh at lines that don't seem like they would be funny to anyone else not familiar with their skits, lines like "beautiful plumage..."

The audience left a lot to be desired. While most of the audience seemed to be people who would appreciate Monty Python, there were a lot of people that struck me as... well, not the type. Old people in expensive fur coats, rich businessmen with hair plugs and their model-thin dates, and a fair amount of young children. But everyone seemed to have a good time, so perhaps the fault is my perception. Sadly, the rail-thin model next to me was wearing too much perfume. The man in front of my son farted when he laughed. The pre-teen girls in front of me were playing a Nintendo DS. A kid behind us looked like a dead ringer for Carrot-Top at age 7.

All in all, very funny. CR and I had a great time.


I attended a great Christmas party in McLean at [info]anyarm's house. It was part of a sisterhood year end event that [info]takayla hosts. There's little to say about it except I had a great time. I watched a dog the size of a greyhound wrestle with a Chihuahua puppy. As part of a blind gift exchange, I got a pizza set, complete with plates, cutter, and pan. yes, it was after Christmas, but no one could find time before Christmas that wasn't in mid-November.

My friend Jason is in town to see his parents. He's a great friend I have known since high school. We met in astronomy class back in 1986, and both of us wanted to be astrophysicists. Well, I was suddenly without parents at age 18 and had to get a crummy job to eat, but he went on to college and is now an Astronomy Professor at Embry-Riddle Aeronautical University in Daytona. He used to always stay at our house over New Year's, but in the last few years, has been staying with assorted relatives and just visiting us.

I wish I hung out with him more. I mean, in many ways he hasn't changed since we were teens, but in others he's got so much more experience. He teaches astronomy and physics with a bunch of other physicists and engineers where he is now. He's probably going to be in Daytona for a while, since he just bought a house, and there's a sales slump. Where he lives, you can watch shuttle launches go by overhead, even though Cape Canaveral is over 100 miles south. We have to visit him... as long as we don't have to drive through Jacksonville...

Santa hat (Punkadyne Labs (Punkwalrus))

Working Christmas Eve

Yes, I am at work. We get off early at 2pm today, which threw a monkey wrench into [info]takayla's day. Right now, as I type this, a bunch of my work mates have gone to get Chinese food. I leave at 2:30 so I can get a ride home.

The Metro was virtually deserted this morning, and I am not surprised. I had forgotten that being in a car with only a few people is kind of nice. Normally my 7am commute is packed to the walls with bitter and angry government workers. I am lucky that I get to sit most of the time. It's because I get on at Vienna, and sometimes the car doesn't fill up before I get to it. But two stops down, it's standing room only. And on some days, notably when it rains or the train has been slow, by Ballston, about 4 stops down, the cars become too packed to get more people on. The Metro simply cannot handle the riders it has anymore. How do they handle this increased business? Why increase their fares, of course. :(

I wore a Santa hat to work. [info]anyarm, who gave me a ride to work, screamed, "SANTAAAA!!" and hugged me, which was a great way to start the morning. ALSO, Mars is the closest to Earth until 2016, and I showed her and Brian Mars, Venus, and the full moon in the morning dawn. Mars is so close and bright, you can tell it's orange. Venus, as always, is a dirty white due to its high albedo. I also explained a little about the ecliptic path. I wish I had become an astronomer sometimes :(.

I know what I want! (Punkadyne Labs (Punkwalrus))

I want to go to Mars! Not like the small town in Pennsylvania, but like the planet. How do I get there? What can I do to get there and back? NASA is too slow.

Who's with me?

So... would anyone actually believe this? (Punkadyne Labs (Punkwalrus))

I got a warning from my SpaceWeather.com mail today that said:
BEWARE THE MARS HOAX: It's August, which means it's time for the annual Mars Hoax. An email is going around claiming that Mars will approach Earth on August 27th; the encounter will be so close, the email states, that Mars will rival the full Moon in size and brightness. (Imagine the tides!) Don't believe it. The Mars Hoax email first appeared in 2003. On August 27th of that year, Mars really did come historically close to Earth. But the email's claim that Mars would rival the Moon was grossly exaggerated. Every August since 2003, the email has staged a revival.
I, personally, have never gotten that mail. I would laugh hysterically at it, and if any of my friends sent it to me, I would pity the education they received as children, because their school system would have failed them.

I wanted to see this letter, so I went to snopes, and 23 popups later, saw the actual text of an example letter. Here's the humorous facts as I see them: first Mars has a diameter of roughly 6800km, and the moon is almost 3500km. This means Mars is almost twice as big. I would imagine that Mars would have to be further away than the moon. The moon varies from 356,000km to 408,000km away. I would imagine that would have us believe Mars was about 700km away from us "at its closest."

Mars orbits at an average of 227 million km away from the sun (like all planets, the orbit is a tad bit elliptical). Earth is closer to the sun, keeping Toronto and Vancouver away from pesky glaciers, at about 149 million km. That's a little over half the distance closer to the sun. Mars has an elliptical orbit, but not THAT elliptical.

The chaos of a flyby that close of a body the size of Mars would be horrific. Space Weather mentioned tides, but that would be the least of our worries. The gravity of a passing body that size that close would alter the Earth's orbit significantly. Assuming it was still in the same orbital plane, it would most likely nudge us into a new path that would send us towards the sun. Maybe not into the sun, but that would be moot. As we hurtled in our new path, if we got close enough to the sun, solar winds would overcome our magnetosphere, and Toronto and Vancouver wouldn't have to worry about those glaciers... or anything... ever again. UV light would cook us, and our atmosphere would strip away like panties at a drunken lesbian sorority party. Oh, and a little known fact: getting closer to the sun makes you hotter! Then, as we headed faster and faster towards the sun, those few humans who holed up in caves with oxygen tanks would find the surface heating up like the mantle below them. Maybe they'd survive. And what a world to come back to! Because when we spin away from the sun, and things cool down... and keep cooling... and keep... hey, maybe we should have turned back at that asteroid belt! No? Still going?

Our orbit would become very erratic like Pluto, and whatever scientists left would be forced to possible demote our frozen ball of rock from "planet" to "no fun at all." Meanwhile, Mars didn't just go away. Whatever forces it encountered to suddenly make a journey of 80 million km off course to our little neighborhood would have it keep on going. Maybe it would crash into the sun. Maybe it wouldn't. Its flyby with us would have altered its path; the Earth's diameter is nearly twice the diameter (size queen) and ten times the mass. Not to mention the moon, who may have seen where this was going and opted not to take the solar tour with us. Or maybe it ditched us near Venus. That planet always needed a moon.

And maybe we'll all meet again somewhere in a million years in a huge welcoming party that looks a lot like rubble going in all directions. I bet Venus will regret keeping the new moon.
