    The Photon energy is the energy for 1 second at a given frequency. For that reason ever cycle has the same energy and we are told that we need higher energy to write on the ball so why can't we just leave it a bit longer? I suggest that it is not the energy of the so called Photon that matters but the frequency. It is said that higher energy at lower frequencies just gives more Photons at lower energy. I suggest that at lower frequencies at lower frequencies just makes the amplitude higher as it does at very low frequencies where we can see the waves on an oscilloscope. The only thing that get's higher at higher frequencies is the frequency and there fore of cause also the energy for ever second.

    Is anyone familiar with Euler’s or anyone else studying this variation of Euler’s contain column studies? The video and white paper describes the mechanical properties related my unique variation of Euler’s Contain Column studies. It shows how materials (representing fields) naturally respond to induced stresses in a “quantized“ manor. This process, unlike harmonic oscillators can lead to formation of stable structures. The quantized responses closely models the behaviors known as the Quantum Wave Function as described in modern physics. The effect has been used to make light weight structures and shock mitigating/recoiled reduction systems. The model shows the known requirement of exponential load increase and the here-to-for unknown collapse of resistance during transition, leading to the very fast jump to the next energy levels. ua-cam.com/video/wrBsqiE0vG4/v-deo.htmlsi=waT8lY2iX-wJdjO3

    Hi, I have one question for you : Let us suppose that we have a function f(q,p) such that f(q,p) = (q+p)^N where N is a positive integer and p is a function of q such that p = 1-q. We can easly see that the function f is equal to one and df/dq = df/dp = 0. My question is, if we use the partial derivative del f/del p, we consider the two variable p and q independant so del f/ del p = N(p+q)^(N-1) which is equal to 1 if N>2. That is correct? Thank you.

    At 4:56 you say that the term is the derevitive of the Lagranian function, but isnt that the partial dererative of L because otherwise how would you descripe the term: "dp/dt" isnt that also the deravative of p with respect to t? And btw love your video!!!

    28:29 Strictly speaking, this equation more reflects that only magnetic dipoles are *known* to exist, not that only dipoles *can* exist. I believe there are string arguments from quantum mechanics that monopoles should exist, but they are as yet unobserved.
