    Hello! There's a new version of this video! Take a look here: th-cam.com/play/PLyu4Fovbph6e0oPk9ch3q2II9a8BT8gfL.html

      But don't we emit IR photons? 😋

    I've been dabbling in physics for about 8 years and this is one of the best videos I've ever come across to really hit home electromagnetism in a deep and intuitive way. And this is clearly because you have a deep intuitive understand of the nature of reality and a wonderful passion, ability to convey it. unfortunately through science text books and some lectures what is actually happening in reality it get lost to abstraction! You have a gift for communication!

      Am i wrong to understand that Einstein was abstractly applying the dopler effect to light and then extrapolating? Without the speed of sound being short enough for us to perceive the dopler effect, would we have ever come to understand relativity?

    I enjoy listening to these, thanks for making a great playlist. FYI (not super important to the topic, but) the solenoid doesn't go back and forth to turn the engine. The solenoid closes the circuit between battery and starter motor, so that the little switch in your steering column doesn't need to have hundreds of amps running through it. :)

    Love the videos!!! Light has geometry, we have Huygens’ Principle of 1670, that says: “Every point on a wave front has the potential for a new spherical wave”. I have read that the electron is spherical and charge is equally spaced on the surface of a sphere. Even fire takes on a spherical shape in zero gravity!

Light's (a photons) trajectory can only be influenced by gravity, magnetism or a transparent or reflective matter.

    How atoms reflect light ?

    • @JasonKendallAstronomer
      @JasonKendallAstronomer  3 ปีที่แล้ว +4

      They actually absorb and re-emit the light. A smooth surface makes a coherent reflection because all the atoms and molecules are in a regular lattice which assures that this process is “the same” among all. To learn more look up Feynman’s lectures.

    Before I listen to this entire lecture which I will, am I not wrong in thinking that light could be the cause of the expansion of the universe since light touches all points of the universe, just like gravity does? If a photon has weight and can push things it makes sense to me, especially if something gets pushed so far out of gravity that it starts flying away
