#til about Braess' paradox. The idea that adding roads to a traffic network can make it less efficient.
It has an interesting physical analogue in a weight hanging from a system of springs and wires. Cutting one of the wires lifts the weight.

#TIL that blowing vs sucking the same spot on a harmonica produces notes that are roughly a half-step apart, while adjacent blown/sucked notes are roughly a whole step apart. I always wondered why I couldn't play any melodies on harmonicas because there would always be some notes I just couldn't find no matter how hard I tried, and now I know the answer isn't some tricky block-holes-with-your-tongue technique like I used to think.
I always knew blowing vs sucking produced different tones, but I thought that they were whole-step transpositions of each other such that any note in one modality would appear somewhere in the other.
My wife showed me this fact and when I asked where she learned it, she said she just figured it out herself...

Screenshot of the following text:

Madame Caroline Testout was a late 19th-century French dressmaker from Grenoble, the proprietor of fashionable salons in London and Paris. She regularly purchased silks from Lyon, which was an important center for rose breeding. The nurseryman Joseph Pernet-Ducher was called 'The Wizard of Lyon' due to his success in developing hybrid tea roses. Madame Testout was an astute businesswoman and understood the value of good publicity. She asked Perner-Ducher to …
Screenshot of the following text:

In 1915, Jesse A. Currey, rose hobbyist and Sunday editor of the Oregon Journal, convinced city officials to institute a rose test garden to serve as a safe haven during World War I for hybrid roses grown in Europe. Rose lovers feared that these unique plants would be destroyed in the bombings. The Park Bureau approved the idea in 1917 and by early 1918, hybridists from England began to send roses. In 1921, Florence Holmes Gerke, the landscape architect for …
