This was the week we all turned our clocks back one hour, thereby disrupting our sleep/wake cycles. And here’s a post about how Ben Franklin, rudely awakened by dawn in Paris, dreamed up Daylight Savings Time.
Blast from the Past: Wilhelm Roentgen discovered the x-ray on November 8, 1895.
In addition to being the birthdate of Marie Curie, November 7 was the International Day of Medical Physics.
Polonium-210: the hard-to-detect poison that killed Alexander Litvinenko was also found in Yasser Arafat’s body (just a few milligrams of the highly radioactive isotope is a lethal dose). Was Arafat murdered? The jury is still out, according to Poison Queen Deborah Blum writing on her Elemental blog at Wired: ” I wouldn’t rule out a poisoning scenario myself; it’s not implausible, given Israel’s ruthless history in dealing with Palestinians and its access to Po-210, that it should be suspected in an assassination plot. But even in the much stronger Litveninko case, there was never what you might call a resolution that included justice.”

The physics of squeezing sheep through a bottleneck. “There are times when mobs have to pass through a bottleneck, such in the case of an emergency exit. If panic seizes the crowd, a jamming can obstruct the way out. This phenomenon displays many features that are also observed with inert particles (e.g. sand, cereal) when they choke the exit of a silo or clog pipe.”
