Fermi proslul svou schopnostĂ jednoduchĂœm a rychlĂœm zpĆŻsobem odhadnout fyzikĂĄlnĂ veliÄiny. PĆi explozi prvnĂ jadernĂ© bomby v Alamogordu v pouĆĄti v NovĂ©m Mexiku 15. Äervence 1945 napĆĂklad upustil kus papĂru z vĂœĆĄky ramen a sledoval, jak se vlivem nĂĄrazovĂ© vlny z bomby odklonil. TĂm, ĆŸe vÄdÄl, ĆŸe epicentrum je devÄt mil daleko, odhadl energii vĂœbuchu â jednalo se o ekvivalent vĂce neĆŸ 10 000 tun TNT.
The âstreamâ we call science always flows forward; sometimes reactionary beavers block its flow, but the stream is never defeated by this; it accumulates, gathers strength; its waters get over the barrage and continue on their course. The advancement of science is the advancement of God, for science is nothing but human intelligence, and human intelligence is the most valuable treasure God has bequeathed us.
I'll bite: Hard science TA's and RA's often repair equipment; it's part of our science. If you want a silver spoon, don't go to grad school. Science is all about dangerous chemicals, semi-safe experimental equipment, and 4am drives down gravel roads in old vans with a nice steep drop on one side. Guardrail? Ho ho ho. Fixing the computers is just the tip of the iceberg. Plus, where else could you get on-the-job experience with a PDP-8?
If physics leads us today to a world view which is essentially mystical, it returns, in a way, to its beginning, 2,500 years ago. ... This time, however, it is not only based on intuition, but also on experiments of great precision and sophistication, and on a rigorous and consistent mathematical formalism.
Most Muggles lived in a world defined by the limits of what you could do with cars and telephones. Even though Muggle physics explicitly permitted possibilities like molecular nanotechnology or the Penrose process for extracting energy from black holes, most people filed that away in the same section of their brain that stored fairy tales and history books, well away from their personal realities: Long ago and far away, ever so long ago.
