[TDIH] Fantasia

On November 13, 1940, the Walt Disney Motion Picture “Fantasia” is premiered in a theater. Contrary to popular belief it’s not the first but the 3rd film. It is, however one of the outliers when you think about Disney movies: it’s basically a classical concert, for which short features were made to go along with the music. As such, it’s the first movie with multiple audio tracks in the room, mixed for multiple speakers. Who needs stereo when you can have an 8-tracks?

  

[TDIH] Bay Bridge Opens

On November 12, 1936, the Bay Bridge opened to actual traffic. It took a bit over 3 years to build and immediately caused “the greatest traffic jam in the history of S.F.”. Nowadays, it carries almost 300 000 vehicles a day. It resembles closely its sibling the Golden Gate Bridge, which is one of the most famous suspension bridges in the world.

Handy recognition tips:

  • if it’s red, it’s probably the Golden Gate (the Bay Bridge being grey)
  • if it’s next to Alcatraz, it’s the Golden Gate
  • if traffic goes only one way it’s the Bay Bridge (top side goes eastwards)
  • if it’s split in two, with an island in the middle, it’s the Bay Bridge
  

[TDIH] Leibnitz Calculates Integrally

On November 11, 1675, Leibnitz demonstrated integral calculus. He was trying to find the area “under” a function. Doing so was quite a feat, opening the door for many advanced mathematical proofs and concepts, but sadly was drowned at the time in the feud between Newton and Leibnitz.

Newton, while a mathematical and physical genius, was petty and vicious towards competition. He tried to erase or diminish any accomplishments not Made-By-Newton™ in his very broad fields of expertise.

In modern calculus, we use the notation for integrals invented by the German mathematician, rather than the Englishman’s.

  

[TDIH] Windows! Windows Everywhere!

On November 10, 1983, Microsoft unveils Windows 1.0. It only does what it says on the tin, and provides windows. Computer Wars Historians still rage today debating the significance of the event, given that Microsoft showed it ahead of the unveiling of the Macintosh (which they collaborated on), but only shipped it 2 years later.

Pundits of the time hated Windows 1.0, which underdelivered on the initial promises.

  

[TDIH] Hitler is Jailed

On November 8, 1923, in Munich, Adolf Hitler tried to seize power through a coup with the early Nazis. The attempt failed, and the future Fürher ended up in jail. Ironically, the trial and the time in the box (where he dictated the first volume of Mein Kampf) made his ideologies known and discussed, spreading support for the Nazis in general.
