Carroll's critique of naive ideas about falsifiability should be seen in context: he's trying to justify multiverse research programs whose models fail naive criteria of direct testability (since you can't see other universes). D. R. Lunsford published a mathematical unification of gravity and electromagnetism which does exactly this, proving cosmological constant = 0. Professor Philip Anderson puts it clearly when he says that the supernova results showing no slowing don't prove a dark energy is countering gravity, because the answer could equally be that there is simply no cosmological-range gravity (due to weakening of gauge boson radiation by expansion caused redshift, which is trivial or absent locally, say in the solar system and in the galaxy). 'I guess, you really have to be R. Penrose to call this 'compulsive reading' (front flap).However, if you made it through chapter 10, the books gets better in the second part.
Woit: By "fake physics" I mean pseudo-scientific claims about physics that share some of the characteristics of "fake news", in particular misleading, overhyped stories about fundamental physics promoting empty or unsuccessful theoretical ideas, with a clickbait headline. I also decided to stick to trying to just give the simplest, clearest, short explanation of concepts instead of giving much longer, more elaborate attempts to convey the idea. The problem with the book is that it's not terribly clear who it's written for. I certainly do hope in the future to write more technical things about the math related to physics that interests me, some of it at an expository level.Peter. On a Completely Antisymmetric Cartan Tensor. Those two parts are pretty good, as far as they go.
Thanks :-) (Now I only have to find someone who tells me how to pronounce this. The volume factor now has weight 3, so the possible scalars are weight -3, and we have the possibilities [equations].
If strings did boil down to just constructing tens of thousands of models and running their properties through a computer I don't think it would last long as a field of enquiry.
Best, B. Lest you think this is all ad hoc coincidence (as occurred in criticism of Dalton's early form of the periodic table), remember we have a mechanism unlike Dalton, and we below make additional predictions and tests for all the other observable particles in the universe, and compare the results to experimental measurements: http://feynman137.tripod.com/ (scroll down to table).
I definitely would not recommend the book to my mum (even though she's a maths high school teacher), or my younger brother (who has a MS). Now, E = Fd implies
I (and many others I suspect) am interested in the matters (failure or not) but don't have the time to look up the details on every of these topics (as research papers are usually hard to read).
hi, thanks.
KKLT is probably the most cited paper in the last 2-3 years and its interpretation might be the most important conceptual question that is also dividing the theoretical physics community to a large extent.If you want to say that it should not really be as important a topic as it is, I might kind of agree.
The two most talked-about books in physics this year are probably a pair of anti-sting-theory books, Lee Smolin's The Trouble With Physics, and Peter Woit's Not Even Wrong, which shares a name with Jacques Distler's favorite weblog. Beyond that range, it doesn't because weak gauge bosons are attenuated while electromagnetic photons aren't.
It is well known that this particle was discovered in 1932 by Anderson [C. D. Anderson, Phys. I simply said: "solve for the 9 3x3 rotation matrix elements in R" (linear problem) & do a transformation (solve for 3D rotation parameters from R).
Few skyscrapers are successfully built starting at the third floor.
Chapter 10 I don't really know what to do with.If Lee Smolin hadn't already said it (back flap) I'd have said the book is courageous, cause it provides all the necessary criticism that was - and is - omitted in most introductions into the subject. You know there's a solution? Well, 'bellwether' is a term of propaganda at this point. Broke open the field, & I extended it to another domain.
My book on the subject was written in 2003-4 and I think that its point of view about string theory has been vindicated by what has happened since then.
He began his career with a 1985 doctoral degree in theoretical physics from Princeton, then held postdoctoral positions in physics (Stony Brook) and mathematics (MSRI-Berkeley) before coming to Columbia in 1989.
If this is the case why bother trying to alter the theories.
In the end, this is a fairly idiosyncratic book, with lots of different parts that add up to an interesting but fairly unique and personal look at the state of the field. We don't see the background electromagnetism field because there are equal numbers of positive and negative charges around, so the net electric field strength is zero, and the net magnetic field strength is also zero because charges are usually paired with opposite spins (Pauli exclusion) so that the intrinsic magnetic moments of electrons (and other particles) normally cancel. The theory therefore predicts the existence of a particle, the positron, with the same mass and opposite charge as compared to an electron. You will find the following very interesting fact: for the average paper the number of full-text downloads is larger than the number of citations. The answer is that attenuated energy is conserved so it is used to give rise to the short range strong nuclear force. Now for the fact explaining the data without dark energy.
This obviously implies that the same force field is producing gravitation as electromagnetism. © 2006-2020 Science 2.0. And Peter himself says this book has "something for everyone" and therefore, necessarily, all of it isn't for anyone in particular. Why not just accept them until there is a problem.
recommend Lisa Randall's 'Warped Passages' which is indeed a very readable, and also entertaining. That is still to be seen. You won't get much LQG in Smolin's book. Rev., 74, p1439, 1948, and 75, p651, 1949; S. Tomonaga, Prog.
Neither does it provide sufficient details to be a technical introduction into the problems and alternatives to String Theory.
Some weeks ago, David from bloggingheads.tv asked whether I'd be interested in contributing to their program by chatting with Peter Woit.During the last years, I found that Peter and I, we share some interests when it comes to the problems of the current academic system, the role of the blogosphere, and the influence of the media on scientific discussions.
)Some people seem a bit mystified as to what Peter's book is actually for, and I'd like to suggest my opinion (even though I haven't read the book, as it isn't yet available in the states). This past summer half a dozen new fish species were discovered…, Sometimes among all of the tedious protocols and mundane inconclusive data, I forget that I'm doing something amazing and incredibly powerful. Have you, post(ed) a "this is what String Theorists hold" vs. "this is what the critique of String Theorists say" breakdown of the world views?
