Many Worlds’ Interpretation – The Universal Wavefunction
Hugh Everett's dissertation, "The Theory of the Universal Wavefunction," presents the foundations of what later became known as the Many-Worlds Interpretation (MWI) of quantum mechanics. Here are the key points…
What exactly were de Broglie’s matter waves?
Also read - Careful when applying E = hv - de Broglie's matter wave energy relation De Broglie actually proposed that ALL matter was essentially waves (of what material -…
E=hv – careful when applying to material particles
DeBroglie taught us that not just photons, but all particles have an energy proportional to their wave like characteristic. For electrons and other material particles, this begs the question -…
Feynman’s Sum over paths approach – some tidbits
Feynman asked the simple question - if you cannot add probabilities - like in the classical case, what CAN you add to get a complete picture? It was obviously going…
Blackbody Radiation Explained
Longer waves should not fit into the blackbox. This means that there should be FEWER waves of long wavelengths (low frequencies). Hence, most of the energy (as you heat the…
A framework to understand the root of entanglement
First read this - Wave or Particle or Neither? If indeed, a particle is a PROCESS (one in which several pulses combine to appear at a point and then dissolve…
Wave or Particle or Neither?
Wave or Particle? (According to Bohm - neither, but definitely closer to a wave) As per Bohm (from the book Quanta and Reality) - An electron is a thing that…
Blackbody radiation – Superposition Principle in Quantum Mechanics
Superposition of multiple oscillators, not possible in classical mechanics (if the oscillators are independent of each other), is what provides the correct values for the blackbody radiation field. The oscillators…
Stern Gerlach Experiment – The Key to Understanding Quantum Behavior
Some Insights - with my own verbiage - from Strange World of Quantum Physics -. Also read The Scales at which Quantum Amplitudes Apply Raw Count leads to probabilities Instead…
Free Particles do not have eigenstates
Since there are no bound energy states (nothing to BIND the free particle), there are no energy eigenstates. All energies are allowed.
