    You need to put safety warnings in the video, not in the blub- many people don't read the blurb. Especially important given how dangerous creating lichtenburg figures in wood is- people have been seriously injured doing it.

    4 years late but this video is short, clear, concise, and gives a great demonstration and visualization of how dielectric breakdown acts in air (hence why when transformers do this the electric arc also rises until the breaking point which I did not understand until you just mentioned about the hot air rising which helped me visualize the whole thing)

    This is hard to understand. Either photons have mass or they don't. My understanding is they don't. Therefore, how can momentum be imparted if mass equals zero? Also there is a second variable related to black body or thermal heating? 😕

    • @Tobincorporated-z
      @Tobincorporated-z 4 місяці тому

      The idea that mass is necessary for momentum comes from classical mechanics. Special relativity tells us that photons actually do have momentum even with no mass. A Crooke's radiometer is meant to be an analog for that, but it works using an unrelated physical mechanism, where light is used to heat things up, as explained in the video.

    sir kindly let me know that what does thickness of the plates has any effect on amount of capacitance. if we have two capacitors of same area A of each plate of thickness 3 mm in 2nd capacitor of same area A of each plate but thickness of each plate is 10 mm. is this condition results in increase of capacitance?

  • @EndlessInquiries
    @EndlessInquiries 9 місяців тому

    Don't you think this is a question of a right combination of the momentum in x direction and y? I mean, as the bullet is lighter, or the x initial speed is faster, it will reach the monkey y axis is a faster time, if the y initial speed is faster, the vertex is the parabola could be further than the original point of monkey. So what is the point?

      My brother in Christ, trail braking necessitates you have brake pressure while turning

    • @rcgldr
      @rcgldr 5 місяців тому

      The primary reason that motorcycles lean in turns is due to the tires being steered outwards from under the bike+rider, leaning the bike+rider inwards. The precession related effect during the initial counter-steering accounts for only about 10% of the roll torque that leans the bike. The issue with braking while turning is that the front tire's contact patch is offset to the inside, and braking will tend to further steer the front wheel inwards, and the rider has to oppose this with some opposing outwards counter-steering torque. Most motorcycles tend to straighten up when leaned, and a rider has to exert some outwards counter-steering torque to steer less inwards in order to hold a steady lean angle. While leaned, counter-steering still applies, steer inwards more to lean less, steer inwards less to lean more. For a rider used to counter-steering, braking in a turn will not be an issue, since the normal counter-steering reaction will allow a rider to hold the current lean angle steady while braking (the rider will also to reduce counter-steering torque when the rider stops applying the front brake).

    Can U make another one to show what happens when U (try to) turn a gyro/wheel, sideways, and what happens when U turn a fully gimbaled gyro thru full 360 degrees. I think U would need to color the gimbal halves and gyro sides differently and be able to show in which direction the gyro is spinning.

  • @curiouscat8396
    @curiouscat8396 11 місяців тому

    What do U mean by "If I try to spin it around this axis, I can raise or lower it"? If U are turning the vertical shaft, then why isn't the gyro precessing/turning? Why don't U show us what happens when U push the back end, of it, sideways.

    What fascinates me as much as the experiment itself are the methods used to achieve such a state. After the explanation at the beginning, while still no small feat, it was surprisingly simple. Basically layers of transparent insulators mixed with pressure reduction, when all is said and done. (Read More). I'm fascinated that one can literally achieve a temperature close to 0 K with a device smaller than a barrel while standing a few feet away at room temperature.
