  • Fun history lesson, Cinco de Mayo was first celebrated in the Mexican communities of California. It celebrates the Mexican victory over the French at the Battle of Puebla in 1862. It was widely popularized by the Chicano movement in the 1950s.

    Battle of Puebla Day was and sort of still is a holiday in Mexico, but it’s not on any official observances list, but school children do get the day off nationwide, and there’s reenactments and parades in Puebla. Widespread celebration fell off after the dictator who was fond of the holiday was deposed in 1911.

    More fun history, the French won the Second Battle of Puebla a year later and then occupied Mexico City in their attempt to found a new Empire out of Mexico, because Napoleon the 3rd wanted one, but was way too incompetent to war with the rest of Europe. (He did some fighting in the Crimean War, but forgot to bring the artillery, the first Napoleon was an Artillery commander)















  • Those systems are interesting, but also nightmares to build and maintain.

    Supercritical co2 is a powerful solvent and can corrode most metals.this problem is worse when you increase the temperature.

    Material scientists are working on it, but so far, the few test systems that have been built can’t quite live up to the hype.
