I have the deepest respect for those who create for the sake of creation -- out of passion, curiosity, creative wanderlust. We need more of them.

In the heart of World War II, as the Nazis took control of Copenhagen, a peculiar situation took place at the Institute of Theoretical Physics, led by physicist Niels Bohr. Two Nobel laureates Max von Laue and James Franck, fearing the confiscation of their gold Nobel Prize medals by the Nazis, had sent their medals to Bohr for safekeeping.

On the day the Nazis arrived in Copenhagen, Hungarian chemist Georgy de Hevesy, who was working in Bohr's lab, devised a plan to prevent the discovery of the medals. Initially considering burying the medals, they quickly dismissed the idea, fearing the thorough searches the Nazis would conduct. Instead, de Hevesy proposed a chemical solution — literally. Utilizing a mixture known as "aqua regia" (a blend of hydrochloric and nitric acids), he set about dissolving the gold medals. This concoction is one of the few substances capable of dissolving gold, a notably unreactive element. As the Nazis marched outside, de Hevesy dissolved the precious medals, reducing them to a colorless solution that eventually turned bright orange. The liquid containing the dissolved gold was then placed on a high shelf in the laboratory, where it remained unnoticed throughout the Nazi occupation​.

Post World War II, upon returning to the laboratory after V-E Day, de Hevesy found the beaker undisturbed on the shelf. The gold was recovered from the solution and returned to the Nobel Prize committee, who then reminted the medals and presented them back to Laue and Franck in a ceremony in 1952.

NASA still has plans to install a radio telescope inside a crater on the far side of the Moon

With no disruption from Earth's atmosphere, it could see further than the James Webb telescope ✨

@anandmahindra The best part is that xuv700 is raising the entire segment up, and of course customer expectations from the manufacturers. Well done.

We are not behaving like we are at WAR.

Every available resource should be deployed.

We don’t have a shortage of resources. We act as if there isn’t a war.

Decisions that should take seconds and minutes are taking days and weeks.

Baffling.
