"All right," you say, "that just seems weird." You pause. "So it's probably something quantum."
Indeed it is.
Don't oriented oscillating E,B fields explain this adequately at the macroscopic level? If you orient a polarizer at an angle theta to the orientation of the E field of the electromagnetic wave (i.e. light), the field gets projected as Ecos(theta) (the component perpendicular to the polarizer gets absorbed) and so the intensity goes as E^2cos^2(theta). That obeys the same mathematics without invoking the quantum magic wand.
I haven't seen meditative practices described much here and I've known first hand how they can help with this level of introspection. So, for those who might wish to try, I'll briefly describe the plain instruction given to zen students. If you want to read in a bit more detail, the thin book "zen in plain English" is an excellent intro.
Sit in a quiet place, with lights dimmed, facing a wall, with your back straight (ex: use a cushion for lower back support). Half-close your eye lids. Adjust your breathing by taking a few deep breaths and then fa...
Thanks for validating what I do :)
What tipped off my original question was lukeprog's phrase "... now consumes whole fields of knowledge in mere weeks". I don't think I can manage that kind of speed with technical material! Months (without multiplexing) is more like it for me.
My question stands for anybody who has any tips for optimizing the "solve the exercises" method.
lukeprog: Your Anki tip is not in vain though. Still useful. Thanks.
Universities subscribe to these databases. There is a kind of redirection via a proxy that happens when I'm logged in via my univ's network which allows me to download articles as you mention. I do have to agree to a "I declare I won't violate copyrights" button before proceeding.
Its cool to be in school :)
Question to lukeprog: Do you have any efficiency recommendations for more technical subjects? Stuff on the lines of Eliezer's quantum physics sequence (aiming more than that, but at least that much). The thing that weighs on my mind most when dealing with such subjects is testing my own competence ... and so it takes me a considerable about of time.
Subject: Basic mathematical physics
Recommendation: Bamberg and Sternberg's A Course in Mathematics for Students of Physics. (two volumes)
Reason: It is difficult to compare this book with other text books since it is extremely accessible, going all the way from 2D linear algebra to exterior calculus/differential geometry, covering electrodynamics, topology and thermodynamics. There is potential for insights into electrodynamics even compared to Feynman's lectures (which I've slurped) or Griffith's. For ex: treating circuit theory and Maxwell's equations as ...
It looks like you just restated the "paradox" - using one argument, it is "obvious" to pick B and using another argument, it is "obvious" to pick both.
Also, in general, do try to avoid saying something is "obvious". It usually throws a lot of complexity and potential faults into a black box and worsens your chances of uncovering those faults by intimidating people.
How would Newcomb's problem look like in the physical world, taking quantum physics into account? Specifically, would Omega need to know quantum physics in order to predict my decision on "to one box or not to one box"?
To simplify the picture, imagine that Omega has a variable with it that can be either in the state A+B or B and which is expected to correlate with my decision and therefore serves to "predict" me. Omega runs some physical process to arrive at the contents of this variable. I'm assuming that "to predict" means &...
