Read about yesterdays history.   Bad weather day for sure.

1915Albert Einstein presents the field equations of general relativity to the Prussian Academy of Sciences.

1926 – The deadliest November tornado outbreak in U.S. history kills 76 people and injures more than 400.

1987Typhoon Nina pummels the Philippines with category 5 winds of 165 mph and a surge that destroys entire villages. At least 1,036 deaths are attributed to the storm.

1996 – An ice storm strikes the central U.S., killing 26 people. A powerful windstorm affects Florida and winds gust over 90 mph, toppling trees and flipping trailers.

Einstein field equations

Since all those equations don't mean  anything to most of us, this is more interesting:

Albert Einstein (/ˈnstn/ EYEN-styne;[4] German: [ˈalbɛʁt ˈʔaɪnʃtaɪn] (About this soundlisten); 14 March 1879 – 18 April 1955) was a German-born theoretical physicist[5] who developed the theory of relativity, one of the two pillars of modern physics (alongside quantum mechanics).[3][6]:274 His work is also known for its influence on the philosophy of science.[7][8] He is best known to the general public for his mass–energy equivalence formula                     E        =        m                  c                      2                                {\displaystyle E=mc^{2}}  E = mc^2, which has been dubbed "the world's most famous equation".[9] He received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect",[10] a pivotal step in the development of quantum theory.
