It’s Tuesday, the last day of April (the 30th), 2019. It’s National Raisin Day, and perhaps I’ll have some in a steaming bowl of oatmeal. It’s also Honesty Day in the U.S., a day whose existence implies that, by and large, Americans are dishonest. It’s also International Jazz Day (a UNESCO holiday). In honor of that, let’s have some international jazz. How about the great Django Reinhardt, who played spectacular jazz guitar using only two fingers (his third and fourth fingers were injured in a fire)? His partner on violin, Stéphan Grappelli, also swings.
It was on April 30, 1492, that Christopher Columbus got his commission of exploration from Spain, and the rest is history (and infamy). On this day in 1789, George Washington was inaugurated as the first President of the United States, taking the oath of office on the balcony of Federal Hall in New York City. On this day in 1803, the U.S. bought the Louisiana Territory from France for $15 million, which more than doubled the size of our country. The price worked out to be just 3 cents per acre.
On April 30, 1897, J. J. Thomson of the Cavendish Laboratory at the University of Cambridge announced, at a lecture at London’s Royal Institution, that he had discovered the electron. Exactly eight years later, Albert Einstein finally finished his Ph.D. thesis at the University of Zurich. In 1927, the first two celebrities so honored left their footprints in cement at Hollywood’s Grauman Chinese Theater. Can you recognize them?
And on this day in 1938, according to Wikipedia, “The animated cartoon short Porky’s Hare Hunt debuts in movie theaters, introducing Happy Rabbit, an early version of Bugs Bunny).” Here’s the cartoon. Bugs, with long ears and face, hasn’t yet become neotenized, according to Stephen Jay Gould’s theory for Mickey Mouse.
It was on April 30, 1945, that Evan Braun and Adolf Hitler committed suicide in the Führerbunker as the Russians closed in, having raised the Soviet Victory Flag over the Reichstag:

On this day in 1966, again according to Wikipedia, “The Church of Satan is formed in The Black House, San Francisco.”
Finally, on April 30, 2008, the Russians confirmed that two skeletons exhumed near Yekaterinburg, Russia, were those of Tsarevitch Alexei and his sister Anastasia, two of the Tsar’s children who were murdered, along with the family and its retainers, by the Bolsheviks. Here are the family’s graves in the wall of Peter and Paul Cathedral in St. Petersburg; I took this in July of 2011, and you can see Alexei’s plaque on the left on the wall and Anastasia’s on the right, facing you:
Notables born on this day include Carl Friedrich Gauss (1777), Alice B. Toklas (1877), Johnny Horton (1925), Bobby Vee (1943), Mimi Fariña and Annie Dillard (1945), Wonder Mike (1957), and Gal Gadot (1985).
Those who died on April 29 include Robert FitzRoy (1865; Beagle commander), A. E. Houseman (1865), Édouard Manet (1883), A. E. Housman (1936), Muddy Waters (1983), and Harry Kroto (2016, Nobel Laureate).
Meanwhile in Dobrzyn, Hili ponders the transience of life;
A: What are you thinking about?Hili: About fading of beauty.
Ja: Nad czym się zastanawiasz?
Hili: Nad przemijaniem piękna.
Diana MacPherson put this great photo up on Facebook:
A tweet from reader Dom:
Video clips captured by camera traps, like the one seen here, give us a window into the snow leopard's world. A camera trap situated in the high mountains of Northwestern China captured stunning footage of a female snow leopard and her two cubs roaming through the snow. pic.twitter.com/kCA4ABvizF

And another cat, this time a jaguar, taking down a croc. I’ve posted this before, but it’s so amazing that it’s worth seeing again:

From reader Nilou, a guy who likes Canada geese and is trying to save one. I hope it was okay in the end.

Speaking of cats on roofs, here’s one from Grania, who loves the photo in the first tweet:
