Fact Of The Day

Newton's second law is not valid for variable-mass systems, such as rockets.

Yes it is, you just have to use the exact mass at the exact time you want to calculate the acceleration. Kind of like a 'snapshot' of it's physical properties.

Marie and Pierre Curie's original notebooks are still sufficiently radioactive that they are stored in a shielded container and people who wish to examine them must sign waivers.

  Sorry Ulthar, everything I know about Physics I learned from Wikipedia ( And Real Genius)

Of those two sources, REAL GENIUS is BY FAR the better source of information.

Wikipedia is feces.

The emergency hotline "911" was designed in 1967 for rotary telephones.

The 9 was because 0 was the operator, & 1 was for non-local calls, thus the next to last number on the dial.
The two 1s were to help rotary phone users dial as fast as possible.

Apollo astronauts had no facilities for going "number two." When one had to poop, he would get completely undressed, climb behind the couches for what privacy he could get, and go into a plastic bag, making sure that everything was caught and sealed inside. Bear in mind that there was no gravity, and the material would not necessarily fall into the bag as one would expect. This reportedly caused situations ranging from minor inconvenience to something resembling the "Baby Ruth" scene in Caddyshack. Further adding to the atmosphere in the command module was the flatulence caused by dissolved hydrogen in the water produced by the fuel cells.

Ummmmm . . . OK!


The youngest First Lady in American history was Frances Folsom Cleveland, who married President Grover Cleveland during his first term of office.  She was 22, he was 47.  When he lost the Electoral College in 1888, she told the White House Staff to look after the place, because they would be back in residence 4 years later.  And they were, when Cleveland won a second term in 1892 - the only American President to serve non-consecutive terms.

I'm so glad I gave up my dreams of being an astronaut!
