When did you last take a Physics class? Adding points (or non-C++ vectors) is a very, very common thing.
It's extremely useful for solving, i.e. the following two problems.
You have four masses of 1 kg each, at (0,3), (2,-1), (4,0) and (2,7). Where is your center of mass?
John, Jude and July are walking home from work. John lives one block north of his workplace. Jude lives two blocks north and one block east of John. July lives four blocks west of Jude. How many blocks east, and how many blocks north, does July live from work?
...And those are pretty mundane examples. There're more.
With few exceptions, I've been "Short Circuit" or "shortcircuit" or some variations thereof since the mid 80s, when I could first pick up a CB mic, and when I first logged into a dial-up BBS. Almost 20 years, and I'm only 22.
I like my name. It's been my identity. It's simultaneously an indicator of my taste in movies and what I do for hobbies. People still see me in public places and shout, "Hey, Short, how's it going?"
And I still get irritated whenever someone registers my name on an IRC network, or on a free email server, or whatever. I still get hung up when trying to log into a friend's machine where he had to truncate my username because it caused formatting issues with tabstops in the config files.
There's a lot in a name. Especially when you've spent years with it, not constantly nym-shifting whenever your inbox got filled with spam.
What if some of your astronauts were married to people still on Earth? The feelings of guilt over infidelity alone could cause a drop in performance.
(And don't think they'd be coasting between planets with nothing to do...there's plenty of experiments that would be more interesting performed in interplanetary space than in orbit around the Earth.
Abort. Don't bother going into a parking orbit around Mars, just swing around back home. With a socially unpredictable or unstable crew, you don't want to risk your science, much less your lives.
You might want to read the first chapter of Stranger in a Strange Land for some brief discussion on this.
It's based on the person, not on the environment. I generally think life is going pretty well for me. I'd have thought that even if I had been born in a cave ten thousand years ago. And I wouldn't have felt any better had I been born in the present day with forty million dollars.
I know a guy who's always griping about one thing or another, despite the fact that he makes more money than me, and he regularly buys PC hardware I don't even bother dreaming about. He'd have been griping if he'd been born in that same cave ten thousand years ago, and he'd have been griping if he'd been born in the present day with forty million dollars.
And, of course, I'm about to know a guy who knows a guy who makes arguments that can't be empiracally proven or disproven.
Not really. Ringworld has design issues I'm trying to avoid. For instance, the ringworld floor material, scrith has a tensile strength on the order of the nuclear strong force. (Someone else's calculations; I haven't checked them.)
I'm trying to keep soltutions as close to modern technology and capabilities as possible. (Though I haven't given much thought to how to disassemble a planet with a gravity well like Jupiter's...maybe flyby and scoop away atmosphere? Build a shell around the planet first, to aid in its disassembly?
I figured on building it like any other spacecraft; you live inside the construction, not on the surface. Hence my interest in the density of the ISS. Those density measurements account for internal living space.
But, yeah. At 1 au, you're inclined to fall toward the sun at 0.0059309 m / s^2.
Me and a couple other guys have been playing around with other aspects. Things like, how do you keep it from collapsing?
...I doubt DNF is ever going to come out. If only because Jack Thompson would describe it as, "The game--long-awaited in the gaming community--where police are mutated into hogs and shot."
I dunno...stats on the ISS helped me figure out how large a Dyson sphere could be. (At 1 au, it turns out to be a shell about 2km thick, assuming transmutation is available.)
The assumption is, the density of a future stationary habitable space construct could easily be near that allowed by present-day technology. And technology improves, so 2km is actually a conservative estimate.
On the contrary, absentee voting (at least, in my township) is very secure.
The ballots are numbered, and they know how many they've given out. If they get two back with the same number, or one back with a number higher than they've given out, they know there's a problem. Ballots are picked up in person from the township office, and mailed back. If somoene wants to let someone else fill out their ballot, that's their decision.
There are laws governing the use and handling of absentee ballots, and they're printed clearly on the ballot. They include things like it being a felony to ask to deliver someone else's ballot. IIRC, there's also laws regulating who can fill out the ballot for you.
But laws can be broken. The physical process in place, though, is sufficient to prevent more absentee votes than absentee ballots handed out, and the people who use them understand the risks of not keeping track of their ballot. It's the voter's risk to lose his own voice, not the government's risk.
I'm not familiar with any similar law in effect here in Michigan.
I work 29 miles from my polling place. That's almost $10 in gas, round trip, to go vote. And my work+class schedule keeps me away from home from from about 5:30AM to 11:00PM on Tuesdays.
Absentee ballots are a much, much better way for me to vote.

It's common for physics programming. And some of the largest computing projects in the world are all about physics.
That's one of the main reasons why huge clusters get built...to perform simulations and process physics data.
It's extremely useful for solving, i.e. the following two problems.
I don't think I ever want to think of the term "circumfix" again. It sounds like a certain surgery gone bad.
My brother told me of someone he'd met at Basic, a certain Ms. Swallow. Apparently, she disappeared before the end of basic.

Yeah, well our dollars theoretically go farther than yours.
Though when you change that to "tax dollars", I'm not sure how it works out.
Oh, come on. I was joking.
Besides, "left" isn't necessarily "Troll."
mod parent down
mod parent up
mod parent a little to the left.
(Don't you wish you could do that now and then?)
Unmarried, no fiancee, no girlfriend/boyfriend. And they didn't break up just to be eligible for the mission.
Come on, it was a joke about light-speed delay.
Maybe I shouldn't have made it after being up for 24 hours...

"Uh, Acquarius, be advised we can hear everything you say, down here."
Bad time to turn on VOX.

The stars provide it for them. Lessee, for us guys, there'd be Andromeda and Virgo.
Hm. Not much selection.
Can you imagine a bunch of astronomy geeks finding dirty pictures in the stars?
...last post!

I got conned out of ten bucks by a guy asking for food money on a Greyhound bus. He asked for three dollars, then kept saying, "Gimme a couple more."
After that, I kept my wallet in the pocket facing away from the aisle.
WoW comes to mind...An API that changes depending on what kind of binary is running.
Why not have a flags section of the binary that indicates the API version?
IIRC, Windows NT is/was (depending on how you look at it) supposed to be POSIX compliant.
Not knowing much about the spec, I can't tell you how well they do at it...
