Caution - Nerdiness

So I was watching Sean Carrol talk about scale in terms of energy in electron volts.. from a neutrino at possibly around 10^-3 ev to 10^37 ev.. the top of the Planck scale at around a freight train's energy.

So Im thinkin..well.. freight train isnt so much.. but then..thats
**for every particle** like.. a few drops of water has trillions..

Mind Blown

In the song Slug, Brian Eno manages to exploit U2 to create a disorienting, exciting tune more worthy of the Talking Heads. The trick is to have Bono intone the same short descending melody over and over, with different lyrics, while the instruments in the background slowly expand and change.

It's important that the lyrics don't make too much sense, and while I said "the same short melody", it's crucially important that sometimes one note changes by one semitone, to create a sense of progression. Putting it all together, the effect is quite dreamlike.

It's structurally like a very different song U2 did....

Edward Teller is mainly famous as the "father of the hydrogen bomb". But he wasn't dumb. He was invited to speak in 1959 at a big party in New York for the 100th birthday of the oil industry - a party put on by the American Petroleum Institute. Over 300 government officials, economists, historians, scientists, and industry executives were there.

And this is what he said:

‘”Whenever you burn conventional fuel, you create carbon dioxide.... The carbon dioxide is invisible, it is transparent, you can’t smell it, it is not dangerous to health, so why should one worry about it?"

“Carbon dioxide has a strange property. It transmits visible light but it absorbs the infrared radiation which is emitted from the earth. Its presence in the atmosphere causes a greenhouse effect …. a temperature rise …. sufficient to melt the icecaps and submerge New York. All the coastal cities would be covered, and since a considerable percentage of the human race lives in coastal regions, I think that this chemical contamination is more serious than most people tend to believe.”
