    Brilliant explanation! This is exactly what I'm looking for! Thank you so much!

    You know they say "The shortest distance between two points is a straight line" so in the parallelogram shape you draw side a + side b will not equal the diagnoal c , but the diagnoal c bisects the parallelogram into 2 traingles so c can be calculated using the Pythagoras theorem c^2=a^2+b^2

      just for right triangle

      For other triangles, you apply the law of cosine where c^2=a^2+b^2-2ab×cos(theta)

    I feel like I'm forgetting something but imagine an atom. So this I think confirms nothing is the same in other star systems. I find it only objectively true. Also, it's useful for zirconium flame measurements for rocket fuel.

      Not only that but you drive at night in the mist. It's a hydrogen eclipse. That has a large effect on the world. Iron oxide is just copper.

      I'm trying to figure out the math for rocket fuel sodium borohydride fusion. So also, I want to be able to calculate these variables without vague thought and the issue I have is that I can look at a chemical and calculate its frequency but I think it's a full ellipse.

      Take for example a neutrino or positron. Photons wouldn't have any mass but I mean they are heavily important in the universe still. Neutrino less double beta decay hasn't even been proven yet so "calculate a frequency," misses something.

      I was reading about a scalar field effect related to photons being massless and I read they used to say "equivalent mass." I imagine these calculations being Similar

    I’m not here for school I’m here because my friend said that she is simping for the man in the video trying to prove her wrong but then I was proved wrong
    Edit: she meant only his voice
