An oft-repeated piece of trivia about the Battle of Mons (1914) is that the rifle fire of the BEF was so rapid that some of the German soldiers believed they were facing machine guns. Is there a reliable source for this factoid?	[ "To put it simply, \"no\". I can't find a verifiable source from any German that actually states that. Plenty of post-war historians like to tout the claim, and you'll see WW1 veterans on the Allied side saying this in interviews or in their own memoirs. I'm a big Lee-Enfield fan.

How does building muscle work? Why does using your muscles result in larger more developed ones?	[ "Muscles are made of long fibers of proteins and other organic compounds.

Questions on space travel	[ "1) Once you get up to speed, you stay that speed. Friction in space is essentially non-existent. (although in low-Earth orbit you do need to compensate for it) 2) Close to, not at or faster. No such propulsion technology exists currently. 3) You'd fire the rockets in the other direction." ]	[ "You could make a significantly less bulky suit out of a highly elastic material using sealed, fluid filled pouches over the body's concavities to keep the body pressurized. However, you'd still need to incorporate a system for regulating the body's heat, and you'd probably want some radiation protection. Since we ...
What is the relationship between gravity and magnetism?	[ "This is a totally unanswered question in physics, and an extremely important one too. Right now, the consensus in physics is that there are four fundamental forces: electromagnetism, weak nuclear force, strong nuclear force, and gravity.

Are high calorie food like chocolate bars more damaging to the environment because the ingredients would cost more energy to grow?	[ "Consuming more energy alone is rarely a problem considering plants already only absorb a really small fraction of sun light that touches them. If anything there's a massive energy surplus.

Why are all the T.V. stations that were for so long true to their origin suddenly all changing to the same, "rigged reality" shows?	[ "Ratings and profit! Reality shows are very cheap to make and get very good ratings, that makes them a good choice for any station who wants to make money, which means all of them. Their goal is cash, not content." ]	[ "It has to do with the contracts the networks sign for the show.

What would happen to a hot piece of wood in a vacuum?	[ "The process of pyrolysis would occur, _URL_0_ where complex molecular chains in the wood broke down into more simple ones like hydrogen gas and various carbon tars.
