Let's throw the question back at the questioner. How many paleoentomologists do we need?

something to do with vacuum creation.But that would create lift from the upper surface, which you and BC do not believe in.
If you live close to an airport it drops the price of real estate but that's better than some places where planes only drop bombs.We had to defend the noise of a gliding club when a new neighbor complained to the local magistrates. He had just bought a house 100 yards from the end of the main runway. Magistrate read the deposition then said "The reason you can buy any house you like is because, among other things, this has been an active airfield since 1939. Case dismissed."
That's why I included bricklaying.Now that is a good idea. Instead of spending a fortune on a stadium and village that doesn't get finished unless you bribe the contractor, and falls to bits the next day, we'll make it part of the competition to build a really good council estate. On track record, I'd back the Polish team to finish on time and in budget, with Team HS2 disqualified before the start.
Post WW3 there may not be much to defend.The entire affair was surreal, and well worth an after-dinner reminiscence. On that particular day we were treated to an excellent lunch cooked on an improvised Soyer boiler (brilliant), with ingredients that our hostess explained would be readily available The Day After: prime Scotch beef and garden vegetables. Evening lectures ranged from bizarre to insane over the course of a year.
One thing I dont understand is that speed is defined as the absolute value of velocity,The term "absolute value" is misleading and unhelpful.
but speed distance /time and velocity displacement / time have different terms in the numerator, havent they?
Please could someone clarify. Thanks.
unmanned and miniaturizedlike a photon, perhaps? And instead of going there to explore the source, we wait for it to come here. Time to invent the telescope - the lazy man's rocket!
The stall demonstrated is the leaking of air from beneath the wing to the top of the wing which creates destructive turbulence, due to the angle and trim that is required upside down and the lack of thrust capability that is required to summount this turbulence that most planes exhibit, this is why the planes have a bit of trouble flying upside down.Air leaking through solid aluminum. Never thought of that before.
What do they agree upon? The gamma ray frequency?The gamma energy, 180 degree coincidence, and the fact that it only happens when a positron emitter is present. And something to do with Einstein and Planck, way beyond my pay grade.
If you measure speed of light in vacuum a trillion times a day, you will also get the same number as coordinate of the great pyramid of Giza.This proving that the Egyptians invented SI measurements (it was actually the French revolutionaries), sexagesimal angular measurements (it was actually the Babylonians) and decimal GPS coordinates (actually the US military).
Possibly the pilot did not want to over stress the airframe by torquing it.It's a serious consideration for transport aircraft. Most are rated for + 2.5 -1g, so don't like sustained inverted flight where the wing root stress is effectively -1g because there is no margin for error or gusts. I've seen a military KC135 tanker fly an aerobatic sequence (with empty tanks!) because the design and demonstrated limits are a bit wider (and the USAF is populated by lunatics) but it's not something you'd do with an airliner even if the seats were empty.
As to how a plane can fly upside down, think why a plane cannot fly upside down.Eppur si muove (Galileo)
