It's a millimeter-wave telescope for studying the polarization of the remnant radiation from the Big Bang. It's going to fly on a high-altitude balloon sometime soon (within the next few days or week, roughly).

A few more pictures:

Mirrors installed. It's an off-axis gregorian telescope. The big tube is a camera for locating stars so we can figure out where we're pointed.

Spent six hours playing NetHack with one break for food and not ascending once. I have been playing that damn game for almost a year and haven't ascended ever.

Today I worked out the equations for a spring in simple harmonic motion. (I already knew them, but had never derived them myself.)

Then, as an encore, I did it for a spring in a gravitational field, which was much more interesting. I may post this to xkcd because parts of it confuse me.

I don't know about me, but my friend just calculated the exact setup of rocket stages for a missile that would deliver a 20 Kg payload 10 Km without exceeding mach 1. He also handwrote a sheet of specs for a spaceship in an RPG that he's playing in my Calc. BC class, including, but definately not limited to, the maximum amount of jerk produced by the main auxilary engine.

As for me, probably programming a game for my calc BC class called "L'Hospital's Asylum". The previously mentioned person designed the graphics. Unfortunately, although we did excellent work, the third person didn't pull his own weight around, and the plot, dialouge, and questions sucked.

First for one, opened the Hunter:the Vigil book, and before even the entire introduction I had already constructed 15 pages of adventure in my head, having finished the first story in it the entire story was at 34 pages on my desk. Took me one additional night going through the book and ended up at 76 pages for the first adventure.

Then yesterday night I built an entirely "New" amplifier for my surround system (since the old one said bye bye after nine years, that's real quality!) from spare parts of other stuff lying around my apartment. And here's the kicker I'm a linguist starting biomedicine this fall, I don't have any degree whatsoever in electronics, I did it by part trial and error and part stuff I learnt disassembling other crap.

Now I only have to wait until it blows up and kills me. Here's to hoping the shrapnel gets some really high speed and kills me on the spot! Cheers!

I have mildew in my bathroom because it is always damp. I got a packaged dessicant today to absorb the moisture from the air. After looking it up online, I found out it's made of calcium chloride. Now I haven't figured out whether the hexahydrate or tetrahydrate is more common but I did figure out the weight percent of water that each form could hold.

Code: Select all
Compound     AW         
CaCl2:       111 g/mol 
CaCl2*4H2O:  183 g/mol 
CaCl2*6H2O:  219 g/mol 

Each 111g of CaCl2 can absorb 73g of H2O in the tetrahydrate. It will absorb ~65% of its weight in water if only tetrahydrate is formed.

Each 111g of CaCl2 can absorb 108g of H2O in the hexahydrate. It will absorb ~97% of its weight in water if only the hexahydrate is formed.

Not sure if this counts, but why not?

I was sitting in the metro on the way to work and poking at the bubbles in the hard plastic sheets they put over the windows (to prevent graffiti "artists" from drawing on/scratching them), and I realised that when I press my nail against it and move it across the bubble, it forms 2 bubbles, and so on. Now, the geeky part, is that the first thing I thought of when I did that was cell division.

I was watching mythbusters the other day, an episode about using match heads as an explosive. I started doing the mental calculations for the volume of explosive etc. Sure thats not that bad, but when you should be mindlessly watching tv, and instead your calculating surface areas and other factors, its pretty bad.

I relatively recently made a basic physics engine to simulate gravity for a game I'm working on. After getting that to work to a point where my game didn't contradict my calculations I felt I earned the right to call myself a nerd/geek.

Wondering why the 'Most geeky thing you've done recently' is in the science forum could perhaps be considered geeky. Other than that, uh, not a lot recentley. I guess palying Munchkin is kinda geeky.

I could try and pick one thing, or I could just kinda give a recap of my whole day:

Precalculus: Got bored, started teaching myself integration from an old calc book I lug around. Solved a leftover problem from ARML.

Chemistry: Argued with my teacher over Lewis diagrams. Finished importing the motor files for my model rocket simulation program (does almost everything Rocksim does, only in 11kB on a TI-84).

Physics: Quietly proved I know more than my teacher by explaining http://en.wikipedia.org/wiki/Cherenkov_radiation to him after he didn't think it was possible. Added adjustments for local gravity (varies 0.5% from pole to equator) and altitude to the program.

(Note: did no schoolwork at all)

Came home, and put the finishing touches on a supersonic mid-power rocket I'm making. Figured out which motor to buy for it. Read the entire archives of a webcomic, looked at these forums for a while.

And that's after coming back from a 3-day high school math competition.

Old thread, but while I was doing a literature search for a review paper I came to realize that one could perform rarefaction analysis on the number of relevant papers found through Google Scholar to estimate the number of relevant papers left. I didn't do it, but the fact that the thought crossed my mind puts me into pretty extensive nerd territory. ;-)

It's a good book but I really think you're over-crediting it. Its exercises are few and don't fit well with the order the text is written in so, whilst it may do an excellent job (as it did with me) of introducing you to a large number of concepts and giving you a bit of understanding of some specific things, don't expect it to provide anywhere near the depth or fluency that you'll get from a university course.

As I said though, it is a very good book and is certainly well worth the read.

Yeah. Now that I've finished it I probably ought to go back to the sections that I didn't quite get (mainly the quantum stuff and the fibre bundles IIRC) and see if it sticks better.

I remember reading fibre bundles A LOT of times before understanding any of it - still pretty sure there's still plenty I missed. I was kinda hoping, after the intense maths of the first half, the physics wouldn't seem as bad - from what you say I guess I was wrong.

The relativistic stuff I mostly got (it also helped cement the tensor stuff from the maths section in my mind), it was mainly the QFT stuff where it started to lose me, but I think that was partly my fault for trying to read that section too quickly.

Yes, although QFT doesn't exactly have a reputation for being easy reading, even by physics standards. It's amazing how much more carefully you have to read it, compared to a normal book. That caught me out at first (as soon as I got past the early bits, which I had seen before).

I programmed a chatbot in my Casio calculator. In BASIC. It could only understand three phrases though. I also did a program that drew arbitrary RLE-compressed bitmaps on-screen (and painstakingly entered a picture of Mario in it), one that drew a 3D cube, a Brainfuck interpreter (obligatory) and even attempted a program to genetically evolve line graphics. Does that count as geeky?

(I was bored in maths class).
