I got into a not-so-friendly argument with a grad school prof teaching me a course in rocket propulsion. Those rocketry guys not only wouldn't use metric, they couldn't even figure out how to use the English system consistently. They insisted on using pounds for mass, so their version of Newton's 2nd was "f=gma"...and they'd cancel pounds-mass against pounds-force whenever they damn well felt like it.
...and weren't averse to letting the gaijin pay a little extra.
I bought OEM oil filters for my 240Z for several years until somebody translated the Japanese label for me. It said "Datsun: 240Z & 510, 1971-up; Ford: all."
Well, not precisely. The Allies -- especially US and Polish troops -- fought continuously to close the Falaise Pocket, but good old Monty screwed it up. He should have reinforced the Americans and Poles, which would have completed the encirclement, but instead he just kept attacking from the West and forcing Germans to fight their way through the gap.
The pocket was bombed and shelled continuously until it was finally closed, and it left so many dead men and horses that reconnaissance pilots barfed when they flew over the scene weeks later.
How could they proceed against a P2P service already using the technique? If the patent holder claimed that an operation in existence before his filing date was using his method, he'd be asserting the existence of prior art and denying the validity of his own patent.
but it takes the equivalent energy of about 620,000,000,000,000 million electron volts (MeV) per second to light up a 100-watt light bulb
Well, if you multiply 2.5 Mev by the number of hafnium atoms in your golf ball and divide that by 620,000,000,000,000, you're gonna need a light bulb that's guaranteed to last for very roughly a millennium.
Umm, yes...and the picture shows what looks like TWO wheels on an axle. You can call it a biwheel or a roller, your choice: either way, gravity constrains it against motion about the longitudinal axis. The monowheel motorcycle contacts the ground at ONE point.
There's a vehicle out there that really IS a monowheel -- it has no axle at all. It's a one-wheeled motorcycle with the driver inside the wheel...I've seen it demonstrated at motorcycle shows. The frame, holding the seat and engine, runs on a circular steel monorail with a tire around the outside of it, about 6 feet in diameter.
It's also a very retro-looking thing, built sometime around the early Thirties.
Thaddeus Lowe, grandfather of "Pancho" Barnes of "The Right Stuff" fame, provided balloon-borne reconnaissance services to the Union Army as a contractor, until he quit the deal in disgust over corrupt contract management in the Army.
Germany used Zeppelins (aka dirigibles) in WW1 for reconnaissance and a small (though dramatic) amount of bombing. As a result of this, the US, which had the only known source of helium in those days, refused to sell it to Germany after the war, which led directly to the Hindenburg disaster. (Yeah, yeah, I know the combustible-fabric story, and if you believe it you can still buy aircraft fabric and aluminized dope and find out for yourself how much of a fire it makes in the absence of hydrogen!)
British cities used "barrage balloons," unmanned balloons tethered over cities by steel cables intended to snag low-flying bombers in WW2.
The entire US coastline and much of the Caribbean were patrolled during WW2 by Navy blimps (and a very few dirigibles) which were ideal for finding and destroying U-Boats -- a capability which can be explored by googling "Brewster angle".
The Japanese fire balloons were aimed at the continental US...Hawaii would be much too small a target to hit. Quite a few reached the States -- I believe one got as far as a Chicago suburb -- but the gubmint pressured police, fire departments and news media to cover up the events as far as possible; there were no really big fires set, and the lack of publicity caused the Japanese to drop the project for lack of apparent results.
No. Wing warping is a directional control technique, and does not alter performance...it was the forerunner of ailerons. Flaps are a performance-altering feature: they make a high-speed wing work well at low speeds for takeoff and landing. Slats and swing-wings are evolutionary improvements on flaps, and the referenced techniques are just the next stage.
They come in pairs eight years apart, once in a bit over a century. The one in 1769 provided the principal funding for Captain Cook's voyage to Tahiti, where it was visible...timing the transit gave a measure of the size of the Earth's orbit.
Y'know, it's funny...when a woman celebrates her fiftieth birthday by buying the toy she's wanted all her life and can finally afford, you don't hear a bloody thing about midlife crises.
Puts me in mind of a fascinating encounter a couple of years ago, when my wife and I were riding a train from Paris to Tours. A young woman in front of us heard us speaking English, turned around and asked where in the States we were from, and that started a long conversation.
Her English was puzzling: grammatically flawless, French-accented, but with another accent mixed in that I just couldn't identify. It suddenly became forehead-slapping clear when we found she was on her way home from a year of teaching French at Sydney University, and that accent hiding behind the French one was Oz.
And at the same time it became clear that her original question was aimed at classifying our accents. Tours is a major center of linguistic education...I suppose the year in Oz was a grad student project.
IIRC, scholars study the isolated communities on the islands along the US Atlantic coast to see what Shakespeare's actors would have sounded like.
As a child in the South in the Forties, I was taught that we were speaking essentially pure Elizabethan English and every other form was a corruption. My linguist uncle, OTOH, says that the true story is that children of colonial farmers, isolated from other white children by the sparsity of the population, were each given a slave child to play with...with the obvious linguistic outcome.
Why don't they, like, have a special draft for lawyers?
Because they get enough by enlistment. You join up as a second lieutenant, get promoted to first lieutenant (at least, depending on experience) the following day, and get some specialty pay...and not every newbie fresh out of the bar exam gets the rich-and-famous contract at a bigtime firm. Some lawyers were drafted during WW2, and lots of doctors.
