In taking IB physics, this feels like the depth of how much we went into Nuclear Physics
“The Antikythera mechanism, one more mystery of the ancient world, is an ancient mechanical calculator (also described as the first known mechanical computer) designed to calculate astronomical positions. It was recovered in 1900-01 from the Antikythera wreck, but its complexity and significance were not understood until decades later. It is now thought to have been built about 100-150 BC. This was some one-and-a-half thousand years before mechanisms of such complexity had been invented. Technological artifacts of similar complexity did not reappear until the 14th century, when mechanical astronomical clocks appeared in Europe.”
Youtube user Brusspup (previously here and here) who often explores the intersection between art and science just released this new video featuring the Chladni plate experiment. First a black metal plate is attached to a tone generator and then sand is poured on the plate. As the speaker is cycled through various frequencies the sand naturally gravitates to the area where the least amount of vibration occurs causing fascinating geometric patterns to emerge. There’s actually a mathematical law that determines how each shape will form, the higher the frequency the more complex the pattern.
NASA makes some of the best logos for their programs (Goddard SPC is my favorite)
I went to look up the laser that guides high energy telescopes. This is the Wikipedia article’s picture for it
Science is the poetry of reality

Anonymous asked: Do you have a favorite periodic table element?
I think Mercury would be my favorite. Its interesting how its the only element liquid at room temperature (and by that I mean by Seattle standards), and comparing its viscosity to water always takes me by surprise. Its really shame with all its great chemical properties that its highly poisonous.
The technical term for the elastic stretching of an object in a black hole is ‘spaghettification.’
