There is nothing new to be discovered in physics now, All that remains is more and more precise measurement
Quantum mechanics brought an unexpected fuzziness into physics because of quantum uncertainty, the Heisenberg uncertainty principle.
Newtonian physics runs into problems at the subatomic level. Down there--in the land of hadrons, quarks, and Schrödinger's cat--things gent freaky. The cool rationality of Isaac Newton gives way to the bizarre unpredictability of Lewis Carroll.
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.
When I was a young man, Dirac was my hero. He made a breakthrough, a new method of doing physics. He had the courage to simply guess at the form of an equation, the equation we now call the Dirac equation, and to try to interpret it afterwards.
Since the founding of quantum mechanics in the 1920s, theoretical physics had nurtured an extremely radical tradition.
The more one chases the quanta, the better they hide themselves.
Statistical physics or Newtonian physics gives way to quantum physics. Very unusual properties of matter emerge at that scale, and you can think about building products in a very different way. You can think about interfacing to biology in a very different way.
Working out another system to replace Newton's laws took a long time because phenomena at the atomic level were quite strange. One had to lose one's common sense in order to perceive what was happening at the atomic level.
It might seem paradoxical that the biggest scientific instruments of all are needed in order to probe the very smallest things in nature. The micro-world is inherently 'fuzzy' - the sharper the detail we wish to study, the higher the energy that is required and the bigger the accelerator that is needed.
Because the theory of quantum mechanics could explain all of chemistry and the various properties of substances, it was a tremendous success. But still there was the problem of the interaction of light and matter.
The electron can no longer be conceived as a single, small granule of electricity; it must be associated with a wave, and this wave is no myth; its wavelength can be measured and its interferences predicted.
All kinds of physical considerations become senseless when we try to apply them to distances smaller than 10 -13 centimeter.
I got into physics through pop science and quantum science and ended up being such a quantum groupie.
In subjects that physicists think of as purely quantum, classical ideas and classical computational techniques can often be powerful.
From a consideration of the immense volume of newly discovered facts in the field of physics, especially atomic physics, in recent years it might well appear to the layman that the main problems were already solved and that only more detailed work was necessary.
Scarcely anyone who comprehends this theory can escape its magic.
Thus, the more precisely the position is determined, the less precisely the momentum is known, and conversely.
The more precise the measurement of position, the more imprecise the measurement of momentum, and vice versa.
The mathematical framework of quantum theory has passed countless successful tests and is now universally accepted as a consistent and accurate description of all atomic phenomena.
I've always been fascinated by quantum physics and the possibility of alternate realities.
So what I'm saying is why don't we think about changing Schrodinger's equation at some level when masses become too big at the level that you might have to worry about Einstein's general relativity.
If anybody says he can think about quantum physics without getting giddy, that only shows he has not understood the first thing about them.
I'm fascinated with quantum physics.
You almost can't avoid having some version of the multiverse in your studies if you push deeply enough in the mathematical descriptions of the physical universe.
