"(...) time in relativity seems to be treated in a manner which is quite different from the quantum theoretical manner. I think Heisenberg was quite aware, very early, of the fact that in quantum theory time is not to be compared with any space coordinate, but is, so to speak, far more basic. You can have all sorts of quantum mechanical systems without speaking of space and position, but you cannot have a quantum mechanical system without speaking of time. In relativity time enters in a manner which, at least apparently, is mathematically symmetrical to the manner in which space enters, and I think that this was an important point for Heisenberg to have thought that here was perhaps something quite different.

The other thing was that, in connection with the finite velocity of light, relativity brought in the necessity of considering actions with the finite velocity of propagation. That meant that the problems of the continuum would enter the game in a manner which was avoided in quantum theory. If you look back into the history of physics, especially of quantum theory, but wherever you go, I think you will always find that the continuum was the point where theories usually broke down. As soon as you treat a continuum as a dynamical entity and not just as a set of coordinates, that is as soon as you say that there is a body with an infinite number of degrees of freedom, in general theories break down. Planck's quantum hypothesis just started by eliminating certain elements of continuity. It may very well be that Heisenberg at that time already felt, as he certainly felt later, that perhaps to unite quantum theory and relativity would mean to do another step against continuity. I remember at that time, or perhaps a bit later, hearing the argument from him that evidently there are three basic constants of nature, because there are three fundamental units in Newtonian mechanics, and two of the constants, h and c, had been found; the third one, perhaps the length, was still to be found and understood."

Kindergedicht von C.F. von Weizsäcker (im Alter von 11 oder 12 Jahren):

"Wenn ich hätt' genügend Geld, um zu leben sicher,
würd' am liebsten auf der Welt ich ein Sternkundicher."

Von hier: http://www.aip.org/history/ohilist/4948.html

My attempt of a translation: "Were I set up nicely, with just enough of dough,
I'd like nothing better than do astronomaugh."

I believe this is commonly referred to as "a groaner" ("Kalauer" in german)...

Didn't see that coming.

Well done, I guess.

A good post over at Karl Denninger's The Market Ticker, introducing me (and, apparently, others) to the concept of "assumed risk":

As commentator John Baker says (#93): "PageRank, Plato and eigenvalues are not the bed fellows you expect in a blog post." Who needs drugs anyway...

From "War is Kind" by Stephen Crane:

A man said to the universe:
"Sir I exist!"
"However," replied the universe,
"The fact has not created in me
A sense of obligation."


From here: http://market-ticker.org/akcs-www?post=229105 (Ahhz's comment)

The owner and writer of the place, Karl Denninger, is a bitchin' teacher with almost unbelievable insight and prowess.

Highly recommended.

Excellent analysis (top comment): http://jordan179.livejournal.com/299925.html?thread=9669781#t9669781

I have been working (on and off) on a theory of physics and politics (no less!), where one crucial insight is "Entkopplung", decoupling, meaning that events or things that were once naturally connected are now independent, which leads to an increase in freedom as well as a decrease in structure/stability. If the latter is to be regained, it will be artificially, voluntarily and consciously.
