  • Is this true? I was listening to a lecture of I think it was a linguist on apes using sign language, saying that the evidence for them actually understanding language is… not great. Like it appear they just sign until their carers gets the right/expected answer. That they may want to say ‘apple’, but not finding the word, they can’t describe the shape, color, just random words util they hit the correct one, or something like that.


  • Well… The effecrive coupling constant changes with energy. A high energy experiment behaves differently than at lower energies. The coupling constant is above 1 for the strong force at low energies, but there is ‘asymptotic freedom’ which makes it below 1 at high energies. For EM it is always below 1. I would guess they reference a ‘bare’ value here.

    The purpose of these graphs are not how they look in our universe though. Rather a common way of doing anthropic style arguments. Without measuring the value of the constants, from the graph we can know from just knowing there are stable carbon and non-relativistic atoms pretty exactly where the values of the constants must be. Similar arguments can be used to pinpoint the cosmological constant from the existance of galaxies.

    Nature is lazy to such a degree that it will even often stop you from doing whatever you are doing so that it can stop doing stuff. For example, Lenz’ Law

    The current induced in a circuit due to a change in a magnetic field is directed to oppose the change in flux and to exert a mechanical force which opposes the motion.

    So basically; if you start playing around with magnets and circuits, nature will induce currents in such a way to stop you. That is next level lazy.
