Until recently there were only 3 classes of solutions to the famed three-body problem. Belgrade physicists just released results detailing 13 new classes of solutions, see them interactively here !
These results are just too awesome. The three-body problem is a relevant topic in classroom physics and mathematics. The fact that research continues on this century-old problem with new discoveries all the time is very exciting to me.
I called it— only a little bit of bragging here— but admittedly I did not base my prediction on anything except the faith carried over from their last epic victory (Ravens vs. Broncos). Does anyone know of interesting research done on the predictability of NFL game outcomes?
My brother collects a lot of prints and he showed me one of her’s that is a fuchsia/pink ‘zombie’ teddy bear. Then I started browsing the rest of her collection and realized that I truly want to own every one of them.
Chaotic orbits are sensitive to very small disturbances. Normally, this feature is seen as an obstacle to prediction, but Belbruno realised that it could be used to advantage. Very small changes in position or speed, which use very little fuel, can cause large changes to the trajectory. That makes it easy to redirect the spacecraft in a fuel-efficient, though possibly slow, manner.

Very interesting applications of chaos theory in orbital dynamics of our solar system; and also some history of mathematics in there for all of us special history AND science geeks.
Conclusion? “Maybe” our solar system has stable orbit :-D
Reductionism persists as a useful node in the possibility space of understanding and managing the world around us. However the possibility space is now expanding to higher levels of resolution such as a focus on complex systems.
I think it is safe to say no one can believe it. All yesterday I was waiting to hear what sick person would/could do this. Turns out he, too, was just a kid. Chalk this up to problems with treating mental illness, or gun control, or school security. None of these are simple in and of themselves… let alone trying to piece it all together. Where can we even begin with this?

I enjoy these RW Quotes. I find them motivating not just for running but often, for the place I am at mentally and emotionally.
Finals/first semester of grad school is over tomorrow at 5pm. Or, depending on your perspective, when I’m done grading calculus exams. It’s been a very tough semester for me in so many ways. My goal by late October was simply to coast through until the end—that’s how fed up with myself I was. Now, I am prepared to keep another important promise to myself:
To spoil myself in positive thinking and relaxing for a substantial amount of time over break. Minimizing negativity, maximizing Zen moments.
To come back in January with the passion I’ve always known I have, but that I haven’t let myself enjoy.
To let it sink in that yea, I am capable. Very much so. I have every resource and nothing in my way. Only the most wonderful friends (old and new), supportive parents, and plenty of great opportunities to look forward to.
I found a new place to live. Moving soon-ish. Again. I find it ironic that all I wanted was to find a place I could “settle” and feel comfortable for a few years… not in the cards apparently…
It’s all good though. I have some amazing, generous friends (Nick and Jessica, to name a few) who have let me stay at their place and gone out of their way to help as I get my affairs in order. Conveniently I needed to take a few days off from running to recover from the race last Sunday; that has allowed me the extra time to catch up on homework and just sleep.
Currently, I’m watching the VTech vs. FSU game. Drizzy is purring. Two beers are empty. Dinner was delicious (if I do say so myself) and despite the all madness and my own self-doubt along the way… life is fabulous.
You could argue that this is fuel for some Debby Downer to find the bad in a series of events when maybe only one of them was truly bad. Or, like me, you can believe that when some really terrible stuff happens to you, it will end with the third in the series… at least for the time being.
It’s a kind of hope that good things are on the way…
1) I lost my apartment. Long story short, my crazy roommate is truly crazy and its not a safe place for me to be anymore.
2) Hurricane Sandy has left my family without power for a week now, and they’re expecting not to have any until next week. The house is OK but the heat doesn’t work. Whenever we talk via phone the signal always cuts out. It’s like the apocalypse there apparently. Sandy&roommate situation happened simultaneously.
3) I got a screw in the my tire yesterday on the way to school and had to make a pit-stop [thankfully a cheap one!] at an auto shop. I’ve got a tire patch but because of where the puncture was, there is a chance it won’t stay and I’ll need to replace the tire anyway.
[Inherent in all of these situations is the fact that I’m perpetually broke and so my options for a solution are always limited by money. Talk about frustrating.]
So this post is not all misery and frustration… my race was on Sunday and I beat my goal time of 10:20 min/miles. Instead, I ran 9:46 min/miles on average! Now, my next goal is 9 min/miles for a half marathon or 10 min/miles for a full marathon…whichever race comes first.
