There is a special Marine Corps plane. It's called the A-10. Hand them over to the Marines instead of scrapping them.
You bojo! It doesn't work on water, unless you've got power!
if they wanted to talk to this guy, Antonio Meucci invented a very useful tool circa 1870 that would've let them do so. Since it's 2015, they could even have (gasp) video! The guy's already in protective custody anyway.
I have, it was fun! Nothing mission critical though. The shipboard stuff was critical however.
A bit low, but reasonable. Try making stuff that goes on ships, there's usually double redundancy AND a completely mechanical system in case everything goes to pot.
Well, division by zero should never happen, but you want it to be handled gracefully in case it does. Nobody wants the autopilot in charge of a barge train to segfault. Basically, every variable in the system was stored three times, past value - current value - predicted future value. If I saw a zero, I could use the past value to get the sign of the zero, and work from there.
True, but since I knew from which direction zero was being approached, and I can't do navigation math with a NaN, I came up with that solution.
Division by zero if anything would be +infinity or -infinity depending on signs, not zero. A while ago I wrote an autopilot that handled division by zero by looking at the signs and setting the result to (maxpos) or (maxneg), the zero's sign being derived from the variable's last value scavenged from the PID function.
I'd imagine that a surface detonation on an asteroid would cause enough mass to leave the asteroid, directionally, to nudge the rest away.
What I generally do with coercive people is conspicuously ignore them other than tell them "if you shout, I can't listen to you". Even works with muggers and cops, if you got the balls. It has happened to me, though, that I had to give a physics demo as to why you don't bring a knife or a taser to a polite conversation.
I couldn't get a Russian visa in time to give a lecture, so we used a telepresence rig that we built. This is already here....
a SD card with a copy of Kerbal Space Program would fit....
Please mod up, this is very insightful.
I can only see the difference between 720p and 1080p if I squint... but I blame TV sizes for monitors for taking away my precious vertical resolution.
