(This post won’t make much sense unless you’ve read Part 1. Sense not guaranteed even if you have.) The Keys to a Shiny New Australia Let’s say I’m in a no-holds-barred game of RISK with @SaintAugustine.* He’s fortified Australia, but I’ve got cards. I plop the cards down; after a grueling campaign it’s come down […]

Bob Was There Too

 

I just finished reading Artemis, by Andy Weir. Yes, I know it’s been out for *checks title page* five years? Really? Man, I am slow at this kind of thing. The good part of not staying up-to-the-minute on these things is that I can get the book from the library because nobody else has it out. The bad thing is that nobody cares about what you have to say by then. But sometimes I’m early; sometimes I… hold on, I’m going to need to get a proper hipster beer to fortify me for this next part.

Now that I’m drinking a Triple India Pale Ale double dry hopped with Simcoe, Callista, and Kohatu,* I can tell you that I’ve been a fan of Andy Weir’s for longer than you have. I’ve read his first novel. No, not The Martian, this is the unpublished one called Theft of Pride. You’ve probably never heard of it. He had a download link on his website. No, not his current website; galactanet, the old one where he hosted his webcomic Casey & Andy. Hold on…

How to Build a Computer 39: Epitaxy II: The Reckoning

 

I know y’all have been waiting eagerly with your wafer in the chamber, the temperature pumped down and your native oxide layer stripped off for me to finish this two-parter. Well, wait no longer! Okay, maybe wait some as you have to find a tank of dichlorosilane to hook up so you have something to epitax onto your wafer. Di-what now?

Dichlorosilane! Or Tri- or Tetra; really anything from SiH4 to SiCl4 works, though I’m told industry generally works with SiCl2H2. Alright, you pump in dichlorosilane gas and react it on the wafer and it puts silicon on top of your silicon. Neat, huh? That’s it! Join us fortnight next for —

Group Writing: Supervillainry

 

Cold, when all is said and done, makes a disappointing superweapon.

I mean, the comic book movies are pretty convincing. The hot superhero shoots a lava jet at the cold supervillain, whose ice ray (not to be confused with a freeze ray) sets out an opposite jet, they meet in the middle and cancel each other out in a brilliant contest of CGI. You get Frozone making walls of ice out of thin air. Or you get the Terminator, freezing in liquid nitrogen and shattering like the hopes of a Hillary voter on election night.

How to Build a Computer 30: SEMsational

 

This is a continuation of last time’s discussion on Electron Microscopy. In that one, we covered the question of why you’d want one of these and gave a summary of how you’d work one. Take some electrons, throw it at your sample, and watch what bounces off for information. Sounds so simple when we put it that way, right? This week we’re talking about what happens when you actually buckle down to do it in practice.

Taken from Chem lab, when there weren’t any chem techs around to stop me.
