  • David Bowie Criticizes MTV for Not Playing Videos by Black Artists

    The Thin White Duke was the persona and character adopted by the English musician David Bowie for public appearances in the mid-1970s.

    The Thin White Duke became a controversial figure due to ostensibly pro-fascist statements made by Bowie in press interviews during this period. Soon after making the comments, Bowie claimed that they were "theatrical" remarks made in character and did not reflect his actual views.

  • Space bending is a general relativity thing, which isn’t really related much to how mirrors work.

    Regarding the medium bit, photons being absorbed and remitted can’t explain how light moves slower in glass. This is just an extremely popular myth. Photons are only absorbed by atoms at very specific frequencies. Also, the entire reason glass is transparent to begin with is that it’s not absorbing the photons (requires too much energy to bump the electron’s energy level so the photon isn’t absorbed and it keeps on trucking). Also photon absorption and remission is stochastic so there’s no way to control the direction it happens in or how quickly it happens. Random directions of remitted light would make glass translucent, not transparent. So for a few reasons, that’s not how it works.

  • Acceleration and Velocity are vectors. Changes in a velocity vector are an acceleration. Therefore when photons change direction technically it’s a form of acceleration.

  • LiDAR is essentially radar that uses light instead of sound

    Radar doesn’t use sound. It sounds like the author doesn’t know the difference between sonar and radar.
