I'm a materials engineer, as my elaborate materials-based solution to the problem at hand probably implied, but not the kind that needs excessive quantum physics and I already had a job lined up at that point. Quantum physics is plenty interesting, but not the point that I need somebody grading...

Back when I was an undergrad, filling out my transcripts with garbage classes so that I could avoid another quantum physics course, I took an electronics packaging class. For a paper, I took a recent journal article about microscopic semiconducting spikes that a small voltage could be applied to...

Heh - never knew you were a Boeing guy. I was still writing for Ars (and at Boeing) when you were there - would've been good to meet up.

The cost isn't extracting it from the earth - you can scoop it up off a beach pretty easily. Titanium oxide is basically the white pigment in paint and sunblock. Stripping off the oxygen and turning it into metallic titanium is where the cost is: http://en.wikipedia.org/wiki/Kroll_process...

I say you get ghetto on it. Pick a set of analogue inputs and and just get (or solder together) a composite RCA switcher. Quick google work reveals an option for $15: http://www.amazon.com/RCA-DT902AV-2-Way ... im_sbs_e_2

Industry standard specs for sintered copper in electrical applications would put you at 20%+ for elongation at failure; meaning it's not overly brittle. Structural copper alloys (no reason for use in a heat pipe) would be 10% or less, so that would pose a problem. That said, the supplier of your...

I think it would work fine, and I honestly wouldn't worry about the finish of the printed surface - run a test or two for yourself, and I think you'll find that the annoying big-hardwood-floor resonance you get is on the mids and lows more than the higher frequencies that would make you wring...

Would you, please? My email is in the profile, just take out the spam trap. I'm sure I was at that Aeromat, but as I'm sure you're aware, you never get to see all the talks to plan on :)

Is any of your titanium fatigue data public? I've heard the claim over and over again, and tested it over and over again, always with significant knockdown in high cycle fatigue. I suppose definitions and baseline targets differ from application to application. Another advantage of working in a...

Slow your roll, folks. Strength isn't a hurdle, nor is precision or rapidity. This really isn't new technology at all, every aerospace firm has had additive capability for a decade plus - the amount of money spent on this technology is truly mind blowing. The problem is finding an application...

I've been using this case for two years now as my HTPC/gaming rig, and although it has a couple quirks as you've pointed out, I've been very happy with it. It looks nice in a home theater setup to boot. BTW, once you do your PC gaming from a couch with proper surround sound and a big-ass screen...

Dibs on the ST2000DL003 if it's still available, pm sent

Going beyond physics, it seems that most people just have a misunderstanding of what PhD level research actually is and what it accomplishes. I work full time as an engineer and work on my PhD in my spare time, and people seem confused when I tell them that my PhD has very little applicability...

No sweat - probably don't need a whole mess of busted iPod threads clogging up the Agora anyways... If you get around to checking it out, let me know - that sounds like what I'm after.

The faithful DJ of my car, a 4gb iPod Mini, finally seems to have given up the ghost. I'm looking for an older iPod (something in the 10gb to 40gb range maybe?) to replace it. Battery life and functionality of the screen mean nothing to me, it just stays permanently plugged into my car's stereo...

Think I've got one for ya, my copy is still in shrink wrap awaiting transfer to the HTPC; I'll check when I get home from work.

I can't be the only one here that really wants to play Carmageddon now.

I might be interested in a batter+charger combo (either your lithium or NiCd) if you decide to part it out - need to check compatibility when I get home. Have a 3 saw set with no batteries that's been collecting dust for a year or so :)

I might have a Radeon 9800 Pro at home... I'll check when I'm done with work.

*shrug* Hooters sells crappy food, and complain all you want, Hooters will still exist until people stop paying for their crappy food. Capitalism!
