What is the difference between Newton and Einstein physics?
The key difference between Einstein and Newton gravity is that Einstein gravity describes that gravity is a curvature in a 4-dimensional space-time fabric proportional to object masses, whereas Newton gravity describes gravity as a force expressed mutually between two objects in relation to their masses.
How is quantum physics different from classical physics?
Classical physics is causal; complete knowledge of the past allows computation of the future. Objects in quantum physics are neither particles nor waves; they are a strange combination of both. Given complete knowledge of the past, we can make only probabilistic predictions of the future.
What is Einsteinian gravity?
GETTING A GRIP ON GRAVITY Einstein’s general theory of relativity explains gravity as a distortion of space (or more precisely, spacetime) caused by the presence of matter or energy. A massive object generates a gravitational field by warping the geometry of the surrounding spacetime.
Why is quantum mechanics better than classical mechanics?
Quantum Mechanics has much more complicated theories than classical mechanics (thanks to Einstein), but provides accurate results for particles of even very small sizes. Quantum Mechanics handles the wave-particle duality of atoms and molecules.
Why do classical mechanics fail?
Classical mechanics or Newtonian mechanics failed to explain the phenomenon like black body radiation, photoelectric effect, the temperature dependence of heat capacity of the substance.
Are Newtonian physics accurate?
Although scientists have known since the early twentieth century that it is a less accurate description of the physical world than relativity theory and quantum physics, corrections required for objects larger than atoms that move significantly slower than light are negligible.
