“There is no physics theory that explains
“There is no physics theory that explains the nature of, or even the existence of, football matches, teapots, or jumbo-jet aircraft.”. “Consequently physics per se cannot causally determine the outcome of human creativity; rather it creates the ‘possibility space’ to allow human intelligence to function autonomously.”
How to turn a block of Antarctic
How to turn a block of Antarctic ice into a giant neutrino detector. “To turn the ice into a telescope, all you have to do is drill an array of 80 holes half a meter across by 2.5km deep using a very powerfull jet of hot water. Then lower a string of 60 optical detectors into each hole before they refreeze, conect them up to some powerful computer analysers and you are good to go.”

Astronomers may have detected the formation of a black hole
Astronomers may have detected the formation of a black hole. “A faint visible-light flash moments after a high-energy gamma-ray burst likely heralds the merger of two dense neutron stars to create a relatively low-mass black hole.”

The Oh-My-God particle is a proton with
The Oh-My-God particle is a proton with the energy of a slow-pitched baseball. And it’s moving so fast that after travelling for a year, it would only be a few nanometers behind a photon travelling at the speed of light.
“Fads, fashions and dramatic shifts in public
“Fads, fashions and dramatic shifts in public opinion all appear to follow a physical law: one of the laws of magnetism”. “Michard and Bouchaud checked this prediction against their model and found that the trends in birth rates and cellphone usage in European nations conformed quite accurately to this pattern. The same was true of the rate at which clapping died away in concerts.”
A near perfect Einstein Ring found
A near perfect Einstein Ring found. Close galaxies can act as a lens for farther galaxies, focusing the distant light with an “Einstein Ring”.
Some bacteria in Africa beat Fermi to
Some bacteria in Africa beat Fermi to the first stable nuclear reactor on Earth by almost 2 billion years. The bacteria enriched the uranium into a critical mass and the flow of water through the reactor kept the reaction going for millions of years.
Genius
This seems familiar:
It made Feynman think wistfully about the days before the future of science had begun to feel like his mission — the days before physicists changed the universe and became the most potent political force within American science, before institutions with fast-expanding budgets began chasing nuclear physicists like Hollywood stars. He remembered when physics was a game, when he could look at the graceful narrowing curve in three dimensions that water makes as it streams from a tap, and he could take the time to understand why.
Dark Sun: The Making of the Hydrogen Bomb
Rhodes’ followup to The Making of the Atomic Bomb (for which he won a Pulitzer), while not as tight a narrative as its predecessor, was more interesting to me because I was less familiar with the story. In particular, the Soviet espionage effort during WWII was fascinating.
