PhD Candidate Talks About the Physics of Space Battles 361

darthvader100 writes "Gizmodo has run an article with some predictions on what future space battles will be like. The author brings up several theories on propulsion (and orbits), weapons (explosives, kinetic and laser), and design. Sounds like the ideal shape for spaceships will be spherical, like the one in the Hitchhiker's Guide movie."

Comment A total waste (Score 1) 950

HRM's on kids in gym class are pointless. In order to be truly effective, they have to be programmed with data that only comes from performing metabolic tests on EACH kid, INDIVIDUALLY. No way the school's going to spend that kind of time on a bunch of rugrats. Likewise, unless they're having you buy some kind of super-mega-intelligent-swissarmyknife monitor, the most it's going to say is "Your heart's going 88 beats per minute." Maybe it'll spit out some sort of "You've burned 42 calories" along with that, but without that metabolic test, that calorie number's bunk. Hell, I've got a $400 watch+strap, and while it gives me lots of other info (calories burned, time spent in exercise zones, peak and average heart rate, average lap time, bluetooth comms for data transfer to my desktop, yaddayadda), it still wouldn't be able to tell me if my heart's about to go into tachycardia, fibrillation, or some other form of improper operation. Sorry, but apart from the "gee whiz" technology factor, there is nothing to be gained by doing this. Throw the kids a soccer ball and tell 'em to keep it on the blacktop.

Submission + - Oregon Public Records Guide Not Publicly Available

An anonymous reader writes: Copyright law has previously been used by some states to try to prevent people from passing around copies of their own government's laws. But in a new level of meta-absurdity, the attorney general of Oregon is claiming copyright over a state-produced guide to using public-records laws. That isn't sitting well with one frequent user of the laws, who has posted a copy of the guide to his website and is daring the AG to respond. The AG, who previously pledged to improve responses to public-records requests, has not responded yet.

Dad Builds 700 Pound Cannon for Son's Birthday 410

Hugh Pickens writes "The Charleston Daily Mail reports that machinist Mike Daugherty built his son a working cannon for his birthday — not a model — a real working cannon. 'It looks like something right out of the battle at Gettysburg,' says Daugherty. The 700 pound cast iron and steel howitzer, designed to use comparatively small explosive charges to propel projectiles at relatively high trajectories with a steep angle of descent, has a 4-inch gun barrel that is 36 inches long mounted on a wooden gun carriage with two 36- inch diameter wheels and took Daugherty about two weeks to build at a cost of about $6,000. 'I've always been interested in the Civil War and cannons, so I thought it would be a good gift,' says Daugherty's 11-year old son Logan. Daugherty said he is not worried about the federal government coming to get his son's cannon because he spoke to the federal Bureau of Alcohol, Tobacco, Firearms and Explosives and found it is legal to own such a cannon because it does not use a firing pin and is muzzle loaded so the government does not consider the weapon a threat. Two days after the family celebrated Logan's 11th birthday, father and son offered a field demonstration of the new cannon on top of a grassy hill overlooking Fairmont, West Virginia and on the third try, the blank inside the barrel went boom and a cannon was born. For a followup they popped a golf ball into the gun barrel, lit the fuse, and watched the golf ball split the sky and land about 600 yards away. 'Any rebels charging up this hill would be in trouble with a cannon like this at the top,' Logan says."

The problem, though, is that in legalese, words don't mean the same thing that they do in common usage, so even reading the whole thing through, common street dweller Joe will think it means one thing, but a lawyer will argue it means something else. Since the ToS/EULA/Contract/Whatever was written by and for lawyers, they win every time, leaving Joe with the bill and about a hundred other street dwellers going "WTF???"

Comment Language (Score 1) 409

God forbid anybody write their ToS in regular, everyday, guy-on-the-street English (or the local language of choice). If it weren't for all the legalese written by lawyers, for lawyers, that only a third lawyer could understand, this sort of crap wouldn't happen. Instead, you end up with pages and pages of babble that most people don't understand, and therefore won't bother to read. IANAL, but couldn't that be grounds to have the whole thing thrown out on the notion of "How can I competently agree to something if I don't have a law degree to understand the blasted thing?"
