    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.




  • Windows XP had been out for quite a while, and I did not want to use it. Staying on 98SE was not going to be possible forever. Ubuntu was quite new, I had recently started uni, and some friends helped me get started. There was one thing that absolutely amazed me: package repository. Just the concept. Windows at the time, to install stuff was finding random pages, sifting through ads, locate download button, hope it is not a virus. Linux had it solved. So far superior it there was no way I’m going back after that.









  • Are you looking to learn linux more or have a easy living experience, or what is the goal? If you want to get to know linux, learn how to compile a kernel, make your own initramfs and such, then: absolutely! If you want a stable easily maintainable system, then… maybe not. Like it is possible, and Gentoo is very stable, but if you are just starting, then you may make choices that do break when you upgrade. With some experience, this will go away, but expect some downtime in the beginning.



  • Someone else was explaining how to tell left from right handed. Buy why is it important? If you do math and physics, you almost certainly would use a right hand system. That means all formulas are derived with that in mind. If you try to use them in the left handed system, you are going to have a horrible time trying to figure out which of all terms need to have their sign flipped.
