 May 7 comment Particles for all forces: how do they know where to go, and what to avoid? You can alleviate much of the confusion by a)discarding the classical notion of a particle being a point like object and more importantly b)thinking in terms of fields interacting with each other, i.e an electron field/proton field coupling with other fields. +1 for a good question. Apr 26 comment Can I get anions by touching the negative electrode of a battery? Sorry OP. I just made it up. In fact this is how it feels after sitting through bio talks. Ron, you might enjoy this-->google.com/… Apr 26 answered Can I get anions by touching the negative electrode of a battery? Apr 24 comment Were the physical constants chosen randomly by the nature? I was under the impression that we chose the constants depending on the units we choose. Apr 14 answered What is “quantum locking”? Apr 8 answered If a measured value is oscillating so fast between two numbers, what does the detector read? Apr 8 comment How do I know an initial speed of a thrown object using the max height Regardless of the syntax, the logic is very simple. Declare $g$ as a double precision constant, $h$ and $v_0$ as double precision arrays, implement a loop within which you read values of $h$, compute $v_0$ and push the computed value back into the array you declared for $v_0$.

Take a look at mini-circuits (minicircuits.com/homepage/homepage.html) and digikey (search.digikey.com/us/en/cat/filters/line-filters/…). Mar 18 comment Does Quantum Mechanics assume space and time are continuous? Modern field theory is based on the Poincare group, i.e., space and time are continuous. Why? No idea. +1 Mar 18 comment Is the quantization of the harmonic oscillator unique? By deformation quantization, do you mean a different kind (parametrized?) of homomorphism? Mar 16 comment What is a general definition of the spin of a particle? You can think of spin as residual angular momentum in the rest frame. Mar 11 comment Accuracy of atomic clocks The theoretical limit would be the linewidth of the line being used (D1 or D2) of Rb or Cs. This is from Heisenberg's time energy uncertainty. The accepted value is 5.3Mhz for Cs (if I remember correctly). Mar 10 comment Why does optical pumping of Rubidium require presence of magnetic field? It would help if you explained how your experiment is setup? What kind of light source, detectors...there are many reasons why optical pumping is getting washed out. Pulsed light or CW light? How are you probing the system? Mar 10 answered Why does optical pumping of Rubidium require presence of magnetic field? Mar 9 comment Does no-cloning theorem implies a no-comparison theorem? How exactly can you obtain a result of your operation without a measurement? Mar 9 answered Accuracy of atomic clocks Mar 9 answered Does no-cloning theorem implies a no-comparison theorem? Mar 9 comment At what angle does a single atom “reflect” a single photon? Just remember that energy, momentum and angular momentum have to be conserved and you will get a spatial probability distribution. Of course, you have to take into account the recoil velocity of the atom as well. Mar 8 answered Why are there 4 Dimensions and 4 Fundamental Forces?
