You laugh, but I know two people who played the dreaded "dodge the lighting bolt" minigame in FF10 and succeeded in dodging the fucing thing for 1000 times.
Perhaps I should explain this without resorting to the use of sarcasm - they are popular misconceptions, after all.
An asteroid, moving through space, has velocity (relatively to the earth) 5 - 20 km/s. Now, most of the earth's atmosphere is about 5 km thick (the rest are light elements scattered in the exosphere). That means it takes less than a second for any asteroid to get though the earth's atmosphere! This is the reason why meteoroids are below freezing (instead of glowing red hot) after they landed on earth - they don't have time to heat up through friction.
Second of all, impact cratering is calculated by the kinetic energy of the asteroid. Size means jack. Which means that as long as the most of the things landed on earth, we get craters.
What all these means is unless you can blow up the asteroid in such a way that they are smaller than your garden's peddles, they will still hit earth. Can fusion bomb do that?
Yes! Through the friction between the atmosphere and the rocks, the temperature could reach over hundred of millions of Kevin and start nuclear fusion right in the comfort of the earth's atmosphere!
Jesus.
and/or be deflected away.
Can someone else take a shot at this? I am busy banging my head against my desk. In all seriousness though, you could deflect some of the pieces off if you can change the velocity of the pieces after you blew them off. But not with the atmosphere...

so it's about 7700 food calories burned to lose 1kg of weight.
yes, and 7700 food calories = 7700 large calorie = 7700 kcal
From wiki: The large calorie or kilogram calorie approximates the energy needed to increase the temperature of 1 kg of water by 1 C. [...]the kilogram calorie is known as the "kilocalorie" and has the symbol kcal.
So for you to lose 1kg, you need to lose 9kcal/g*1000g = 9000kcal = 9000000cal, not 7000cal. Well, I guess if you heat 9000litres of water by 1 degree with your bodily warmth, I guess it is possible.

Dugald Christie died on a years-long mission of conscience drove him for years
He bicycled to work. He lived in a rented basement suite. He was a transplanted Scot who eschewed scotch but drank hot water with cream and sugar. A devout Anglican, he kept his offices in a church, arrived for work at daybreak and left, usually, 12 to 14 hours later. He could have made lots of money in his lifetime. He chose instead to make a difference.
Dugald Christie was a lawyer, but he was not like most lawyers. He was not like most people. A colleague called him "the Mother Teresa of the bar." When the Trial Lawyers Association of B.C. honoured him for his life's work in March, he was introduced as being "every lawyer's conscience of their professional obligations" -- this high praise earned in a profession often accused of not having a conscience.
He died Monday at the age of 65. He was struck and killed by a minivan on the Trans-Canada Highway near Sault Ste. Marie, Ont.
He was riding his bicycle, and it was his conscience that had brought him to that fateful place.
He was cycling across Canada to raise awareness about the average person's lack of access to the judicial system. Christie called it the ABCs of true justice -- affordable, brief and comprehensible -- and he was gathering signatures along the way on a petition he was going to present to Prime Minister Stephen Harper. His ultimate destination was St. John's, N.L., where he was to address the Canadian Bar Association.
Christie was the founder and director of the Western Canada Society to Access Justice.
Its work is all done pro bono -- the waiving of legal fees as a charitable act -- and it was Christie's job, or rather his cause in life, to get top-flight lawyers to represent needy clients.
He did this through sheer hard work. Christie was an indefatigable and constant presence -- as good consciences are -- and he was always working the phones to get donations or a lawyer's help.
He knew almost every lawyer in town, and his calls enjoyed a sort of fame among the legal community. With a trace of his Scottish brogue, he would open, simply, with "Dugald Christie here," and the lawyer on the other end of the line knew it was time to pony up.
His work paid off. By the time of his death, Christie and the society had 61 clinics from Campbell River to Winnipeg and more than 400 lawyers donating their services. He made it into the largest legal aid service in the province.
"I have tremendous respect for his ability and commitment to pro bono work," said B.C. Supreme Court Chief Justice Donald Brenner, "and I know that he had a goal that his clinics would be available to 95 per cent of all British Columbians. I think he achieved that this spring."
Brenner was a fan of Christie's.
"I have in the past described him as not everyone's cup of tea, but he was an achiever, a man who didn't just talk about doing good, but worked hard to do good, and I have great respect for him. I use that old journalistic saying to describe him: He comforted the afflicted and afflicted the comfortable."
More often than not, he afflicted those in the law itself.
n 2003, he filed a formal complaint against B.C. Court of Appeal Justice Mary Southin, accusing her of encouraging people to defy smoking laws while continuing to sit in judgment of others.
He maintained Southin had "brought the administration of justice into disrepute" by refusing to stop smoking in her office, despite a 1998 Workers' Compensation ban against smoking in the workplace. He filed the complaint after it was reported then attorney-general Geoff Plant had okayed a $19,000 ventilation system for her office at the Vancouver Law Courts.
But it was Christie's prolonged fight against the province's move in
I will try to ignore the whole "visual novel == hentai with tentacles" arguement. I play/read visual novels (or AVG as they are properly called) so I will be biased.
That having said, there was a pretty famous incident that involved GPL and a Japanese AVG game makers. Apparently the company used Xvid codecs for their animation clips for their popular games (ranked top 10 ero-game in 2005) without releasing the engine source code. When someone pointed out the GPL, the company promptly released the whole engine code (without the comments unforturnately). The engine was designed with win32 API in mind, btw. But it still counts as something
Off topic: I was amazed that a Japanese hentai game maker respects the GPL more than, say, SCO, a multi-million dollar company; Then again, comparing SCO to a hentai game company would not be fair- to the game company:).
From TFA: But soon, RS Oph could pass the tipping point - the nuclear flame will detonate from deep inside the star and blow it apart. How soon is not clear.
"It could be tomorrow, but most likely it'll be 1,000, 10,000, 100,000 years from now," says Jeno Sokoloski.
Wow that's some long life astronomers. I wonder if they will be around to see DNF getting release.
With that out of the way, let's take a look at orbital dynamics. You can't actually throw anything (or yourself) out of orbit--all you can do is throw an object, or move yourself, from one orbit to another. If you want to go to a higher orbit, you need to increase your speed in the direction you're traveling. If you want to go to a lower orbit, you need to decrease your speed. Just trying to thrust straight up or down won't work too well: Thrusting down, for instance, will lower you temporarily, but now you're going too fast to stay in that lower orbit, and you'll end up oscillating back above your original orbit. As science fiction author Larry Niven put it, "East takes you out, out takes you west, west takes you in, and in takes you east."
To get those baseballs to earth, you want to throw them back from the shuttle. Now they're traveling slower. The effect of this is to put them into an elliptical orbit, whose apogee--the point furthest from the center of the earth--is at the same height as the shuttle. If the orbit is elliptical enough, then its perigee--the point closest to the earth's center--will be closer than the surface of the earth, and the ball will collide with the earth after half an orbit or less. But if it doesn't hit the earth (and if we ignore atmospheric friction for the moment), it'll stay in that nice comfortable elliptical orbit indefinitely.
Now for the specific problem of astronauts throwing fastballs: The space station is at a height of about 390 km over the surface of the earth, for a total distance of 6,768 km from the center, and it's traveling at about 7,674 m/s. Our 93 MPH pitch translates to about 42 m/s, so the total speed of the ball is then about 7,632 m/s. Given that energy and angular momentum are conserved, it's straightforward (if a bit tedious) to calculate that, at perigee, the ball will be 6,623 km from the center of the earth, which is still a comfortable 245 km above the surface.
But this is all figured without the atmosphere. Won't friction from the topmost layers of the atmosphere cause the ball's orbit to decay, and eventually bring it down? Yes, but that would happen even without pitching the ball. If left on its own, the space station itself would eventually fall to earth, but they boost the orbit every so often to prevent that. In fact, that's why Mir was deliberately brought down: The Russians didn't want to keep boosting it any more, and they knew that eventually it would come down on its own.
Well you would die eventually, but it won't be speedy.
Remember, if you are in orbit with the earth, you have angular momentum- if you moving horizontally and vertically at the same time. I won't show you all the fancy calculations but take my words for it. When you push yourself towards earth, you will just descend into a lower orbit that is more elliptic.
If I remember correctly, however, the ISS is placed on a polar orbit that is quite low in attitude. Therefore there is a small but present air resistance. That will gradually slow your horzontal velocity down. At the end, your orbit will become more and more elliptical until gravity overcomes the angular momentum.
But you would be long dead before that due to suffocation.
Wow, I was just reading the article absent-mindedly until this paragraph caught my eyes:
By spinning astronauts and then testing them in the "balance booth," Paloski hopes to learn how to facilitate the transition from one state to another. His subjects will be crewmembers of shuttle mission STS-107, which is slated for launch in January 2003. "We plan to test these astronauts both before and after the mission," he says.

How fast did the initial surge of molasses travel? Experts and eyewitnesses agreed on 35 mph, but we needn't take their word for it. I consulted with Gareth McKinley, professor of mechanical engineering at MIT, and established that the theoretical maximum rate of flow for a (roughly) 50-foot column of liquid, ignoring density and viscosity, was 38 mph. Surprisingly, molasses's stiffness would have slowed things only a bit--making certain assumptions about Reynolds number and whatnot that I expect some gratitude for not sharing, the flow rate would have been mostly a function of inertia (i.e., mass) rather than viscosity. Bottom line: 35 mph was a pretty good guess.
[mother]:"I asked, 'If this is such a serious threat, did you call the FBI?' They said, 'No, we don't have time for this.' I asked, 'Did you call the Joliet police?' and they said, 'no.'"
Don't have time? Don't have time?!
So what you are saying basically is that, rather than going thru the annoying route of reporting to the police, you are just going to expel the kid? I guess the kid's 60 years worth of future is too unimportant compared to your job huh? I mean, we wouldn't want your daily wanking^h^h^h^h^h^h administration sessions be interrupted.
I can't believe this. We are entrusting our childen to these...educators?! No wonder Columbine happened you idiots.
Remember, to a school, there are thousand of students; To a student, however, there is only one school. So please, get it right.
Don't expect to sell your first generation of platform (or architect). It sucks. You know it, the customers know it. Instead use it as a phototype to get feedbacks from.
