Hmm. What to go with for today's countdown?
18 - secret code name for Adolf Hitler?
18 - the atomic number for the noble gas argon.
Argon constitutes 0.934% by volume and 1.29% by mass of the Earth's atmosphere, and air is the primary raw material used by industry to produce purified argon products. The Martian atmosphere in contrast contains 1.6% of argon...
2 1/2 weeks. Wow.
