Space
Space Shuttle Atlantis will lift off in four days time carrying a sliver of wood cut from the apple tree under which Isaac Newton felt the sudden impact of gravity.
The actual tree no longer exists, of course; but the sliver in question was cut from the original tree by Newton himself and is in fact signed by him.
In 2006, British Astronaut Piers Sellers on his first voyage into space carried a gold medal struck by the Royal Society which was presented to Stephen Hawking.
Now on his third voyage, he asked the Royal Society what he might be able to do for them. Thus was born the idea of linking Newton and gravity to a weightless environment.
"I'll take it up into orbit and let it float around a bit, which will confuse Isaac," Sellers said in an interview with The Associated Press earlier this week.
The irony is quite wonderful.
The Royal Society is celebrating its 350th anniversary and as part of this year-long event has been promoting its long history; for instance identifying and publishing the 60 most memorable
scientific papers and more recently the memoirs of
William Stukeley one of Newton's first biographers.
The memoirs include a hand-written tale of the actual apple event:
"
After dinner, the weather being warm, we went into the garden and drank tea, under the shade of some apple trees. He told me, he was just in the same situation, as when formerly, the notion of gravitation came into his mind. It was occasion'd by the fall of an apple, as he sat in contemplative mood. Why should that apple always descend perpendicularly to the ground, thought he to himself."
