Zitat des Tages über Quantenmechanik / Quantum Mechanics:
I finished up my graduate degree in quantum mechanics, but underwent a bit of a personal crisis, recognizing that I didn't want to do that for the rest of my life. It was too abstract, too far removed from human concerns.
Quantum mechanics brought an unexpected fuzziness into physics because of quantum uncertainty, the Heisenberg uncertainty principle.
Quantum mechanics broke the mold of the previous framework, classical mechanics, by establishing that the predictions of science are necessarily probabilistic.
No one intuitively understands quantum mechanics because all of our experience involves a world of classical phenomena where, for example, a baseball thrown from pitcher to catcher seems to take just one path, the one described by Newton's laws of motion. Yet at a microscopic level, the universe behaves quite differently.
Now, what that means is that there is fundamental indeterminacy from quantum mechanics, but besides that there are other sources of effective indeterminacy.
The development of quantum mechanics early in the twentieth century obliged physicists to change radically the concepts they used to describe the world.
The scientists often have more unfettered imaginations than current philosophers do. Relativity theory came as a complete surprise to philosophers, and so did quantum mechanics, and so did other things.
If you start any large theory, such as quantum mechanics, plate tectonics, evolution, it takes about 40 years for mainstream science to come around. Gaia has been going for only 30 years or so.
In relativity, movement is continuous, causally determinate and well defined, while in quantum mechanics it is discontinuous, not causally determinate and not well defined.
Quantum Mechanics and General Relativity are both accepted as scientific fact even though they're mutually exclusive. Albert Einstein spent the second half of his life searching for a unifying truth that would reconcile the two.
If we look at the way the universe behaves, quantum mechanics gives us fundamental, unavoidable indeterminacy, so that alternative histories of the universe can be assigned probability.
While classical mechanics correctly predicts the behavior of large objects such as tennis balls, to predict the behavior of small objects such as electrons, we must use quantum mechanics.
Einstein was searching for String Theory. It not only reconciles General Relativity to Quantum Mechanics, but it reconciles Science and the Bible as well.
The problem is that replacement of Quantum Mechanics by Quantum Field Theory is still very demanding.
I'm not looking to be a trophy. When not acting, I spend my time studying metaphysics and quantum mechanics to keep my life as grounded as I can.
In 1924, I became a Dozent in Gottingen and worked out the quantum mechanics during a holiday stay on Heligoland.
What you can show using physics, forces this universe to continue to exist. As long as you're using general relativity and quantum mechanics you are forced to conclude that God exists.
The math of quantum mechanics and the math of general relativity, when they confront one another, they are ferocious antagonists and the equations don't work.
The most important single thing about string theory is that it's a highly mathematical theory, and the mathematics holds together in a very tight and consistent way. It contains in its basic structure both quantum mechanics and the theory of gravity. That's big news.
One of the most exciting things about dark energy is that it seems to live at the very nexus of two of our most successful theories of physics: quantum mechanics, which explains the physics of the small, and Einstein's Theory of General Relativity, which explains the physics of the large, including gravity.
There's a lot of things I nerd out over. Quantum Mechanics. I also love Dungeons and Dragons. I want to be an astronaut.
