Hey, I wanted to ask you guys a few questions about string theory. It seems like a really neat area, but is over my head. These questions are based on stuff...
string theoryF-theoryD-branesWe discuss the field theory of 3-brane probes in F-theory compactifications in two configurations, generalizing the work of Sen and of Banks, Douglas and Seiberg. One configuration involves several parallel 3-brane probes in F-theory compactified on T/Z, while the...
Evidence for $F$F-theory. Seiberg, N; Witten, Edward C Vafa - 《Nuclear Phys B》 被引量: 2374发表: 1996年 Small Instantons in String Theory A long-standing puzzle about the heterotic string has been what happens when an instanton shrinks to zero size. It is argued here that the answe...
Some very interestingstudent questionsthis week. We're going to talk about what the heck string theory is and why it's important, if it is; a problem affecting nearly half of Asian people when they drink alcohol called the Asian Flush reaction; economics applied to traffic in the form of ...

We use autoRange: EAutoRange.Always, so in theory, the candles and lines should always be visible. The problem occurs when we have 1 candle or 1 OHLC and with the line chart when a new value goes beyond the current range – the value axis update only happens after the second new ...
I am delighted to announce that the 10th edition of my textbook, Price Theory and Applications, is now available wherever good books are sold. There’s also a free sample chapter. Here’s what’s special about this edition: I started out by rereading large parts of the past several edit...
Testing limits: what science can and can’t tell us about the universe Dine often adopts the tone of a wise university tutor, at one point even discouraging new graduate students from a career in theoretical physics given how hard it is to make a significant contribution to scie...
Superposition is one of those things we absolutely cannot escape. Although there are plenty of disagreements at the fringe of quantum theory (as there ever should be), the idea of superposition is not one of them. It’s bedrock. It would be like competing climatologists arguing about whether ...
