  • I’ve lost hearing young due to a health condition. The sales model for hearing aids is depressingly close to the Black Mirror episode with Rashida Jones.
    The hearing aid costs 15 per month on “basic”, rising through eight different tiers, to “platinum plus” at 120 per month. The hardware doesn’t change, only the software. So if you want to be able to hear nature sounds, that’s an extra 10 per month. An extra 20 to hear conversations in the car. It’s 50 if you want to be able to go to a concert, and so on.
    The hearing aid itself is capable of doing all of that, all the time, but the functionality is just switched off.
    The term is 4 years and then it becomes obsolete and receives no further updates; you have to get a new one.
    This is in the UK.





  • We make the following assumptions:

    1. We are not in a privileged or special place in the universe.
      1a. Therefore the universe should look the same from where we are as from almost anywhere else.
    2. Supernovae emit a very reliable amount of light.
      2a. Therefore we can accurately tell how far away a supernova is by its light signature.
    3. We can tell how far away distant galaxies are when a supernova goes off in them.

    Therefore, we can map out and count the galaxies in our local area, and, using assumption 1, we know that the number of galaxies in our volume of space is the same as in every volume of space. Multiply the one by the other and you’ve got your answer.
