In 1925, Nome, Alaska was hit by a diphtheria epidemic and all the available antitoxin had been exhausted. Since land, air, and sea routes were not feasible, 20 mushers and 150 sled dogs bravely carried the serum over a distance of 674 miles in just 5 and a half days despite harsh subzero temperatures, near-blizzard conditions, and winds reaching hurricane force.

Dennis Ritchie

Dennis Ritchie, the creator of the C programming language and co-developer of the Unix operating system, passed away one week after Steve Jobs.

Schweres Wasser

During World War II, the Nazis developed a secret weapon named the “Schweres Wasser” (Heavy Water) which was a isotope of water that was enriched in the hydrogen isotope deuterium. This heavy water was used in the production of nuclear weapons but the allies became aware of this and they launch an operation to sabotage the heavy water production in Norway. The operation was successful and it slowed down the Nazi’s Nuclear weapon development program which in turn changed the outcome of the war.
