“Now I am become Death, the destroyer of worlds”*…

 

Your correspondent is old enough to remember the Cold War and the Civil Defense efforts (booklets, films, duck-and-cover drills) aimed at “preparing” us for atomic conflict.  It’s a sad sign of our times that they’re re-emerging:  “Where to Hide If a Nuclear Bomb Goes Off In Your Area.”

(If there’s a silver lining in this fallout-laced cloud, it’s that it’s re-directing attention to a problem– a threat– that never actually went away; c.f., Ploughshares.)

* J. Robert Oppenheimer

As we enter the Twilight Zone, we might recall that it was on this date in 1903 that The Times (London) newspaper reported that Marie and Pierre Curie communicated to the Academy of Sciences that the recently discovered Radium…

… possesses the extraordinary property of continuously emitting heat, without combustion, without chemical change of any kind, and without any change to its molecular structure, which remains spectroscopically identical after many months of continuous emission of heat … such that the pure Radium salt would melt more than its own weight of ice every hour … A small tube containing Radium, if kept in contact with the skin for some hours … produces an open sore, by destroying the epidermis and the true skin beneath … and cause the death of living things whose nerve centres do not lie deep enough to be shielded from their influence.

That same year the Curies (and Antoine Henri Becquerel) were awarded the Noble Prize in Physics for their work on radioactivity and radiation.

In lieu of a graduation address…

… from xkcd:

As we avoid looking too closely at the faces of our watches, we might recall that it was on this date in 1921 at the White House that President Warren G. Harding presented Marie Curie with a gram of radium (worth $100,000 at the time).   Curie died in 1934 of aplastic anemia contracted from exposure to radiation.  Her laboratory is preserved at the Musée Curie.  But because of their levels of radioactivity, her papers are considered too dangerous to handle, and are kept in lead-lined boxes; those who wish to consult them must wear protective clothing.
