I'm surprised that the OP didn't mention reverse flies. I developed terrible RSI and upper back problems when I hit about 30. One of the biggest problems was my posture: slumping shoulders. By the time I got to this point, I could not physi

IIRC, the author didn't even really object to the computational model (aka "Newtonian Schema"). He just argued that it should not be the only one taught, as the "Lagrangian Schema" has some distinct advantages.

I think you misunderstand the paper. And, in fact, I think the main point of the paper should be completely uncontroversial to anyone with even a lay understanding of GR. The point of the paper is that apparently the yout's of today are bei

by nessus42 14y ago
It does not. It does not say or imply anything of the sort. In fact the point of the paper should be "obviously true" to anyone who has even a lay understanding of GR.

Thanks muchly for that excellent summary! Yes, I would like copy of the paper. Please send it to doug at alum dot mit dot edu. Thanks! > And killing the rat afterwards does not undo it. Yes, sorry; it's been a long long time since I'v

My new Chromebook is so cheap that I just bring it everywhere. If I lose it, no biggie. I love my 11-inch MacBook Air a lot more, which means, ironically, I leave it at home because I couldn't bear to have it damaged or lost. Also, I have t

And even if you do like tablets, typing even relatively short messages on a tablet is seriously non-fun. The keyboard on the new Samsung Chromebook is fantastic; basically a clone of a MacBook Air keyboard. The touchpad also works really

Have you used one? I love mine. It just works. And it's cheap. The battery life is 6 hours. What makes that poor?

He has a book. I haven't read it, but I'm sure he must discuss this issue in it. In any case, I'm sure you can come up with a definition of "measurement" that might make the Copenhagen Interpretation experimentally indistinguishable from MW

I want to reiterate here that MWI is a much simpler theory than Bohm's, even if the consequences of MWI might seem more complicated. At times, there have been scientists who want to apply Occam's razor to the consequences, but most scie

No, it's an analogy , not a theory. There are no hidden variables in the Many Worlds Interpretation, but it will appear to us as if there are. The Bohm Interpretation is the experimentally indistinguishable dual of MWI that proposes hidd

by nessus42 14y ago
You might as well say that the Bohm interpretation is "like religion" then, rather than saying that the MWI is. If your assertion is that we might never know which is true, the Many Worlds Interpretation or the Bohm Interpretation, then you

I'm pretty sure that, in theory , all the major interpretations of QM are experimentally distinguishable from each other. The feasibility of ever being able to perform some of these experiments, however, is rather questionable. Two excepti

Relativity says that you can't construct a rigid beam 25 million miles long.

This article completely ignored the Many Worlds Interpretation, which preserves all of realism, locality, and Relativity.

Personally, I think that this whole "oral exam" style of interview is completely wack. If you have a lot of experience with it, then you are likely to do great, and if you don't, then you are likely to suck at it. When I was in high school,

Oh, at this point in my life the silly questions that I asked are just terribly embarrassing to me! I'm sure that you can locate it though, if you really care. The truth is out there!

I interviewed Kate Bush a long time ago. This may or may not impress you, but since she's a notorious recluse, it's quite impressive to anyone who is a Kate Bush fan. Q. How did I do this? A. I made it my life's goal for a couple of years.

Yes, that is strange. It looks more like the mid-term of the linear algebra class that I took at MIT: i.e., 18.700. And I have to say that 18.700 was one of the easiest classes that I ever took at MIT. It's kind of a bummer that they gave m

The session information is cryptographically signed, so you don't have to trust it! These stateless server frameworks are just using the client as a state cache.
