Dear Bee, mucho phhysics for the interview. All this will do is galvanise people to work harder to provide evidence to prove or disprove any theory that tries to describe realty.

It’s been two decades and string theory has yet to produce any hypotheses that are testable, with current technology In Witu Universe in a Nutshell Hawking writes that you need a particle collider larger than the size of the universe to prove some aspects of string theory, and that’s fine with him.

Of the above, I’d recommend Greene’s work and then try Smolin. Folks should get off their duffs and do the parity experiment. However happiness cannot be eternal and after years of uncontrolled outrages Einstein’s cult will have to disappear. And, in the three decades preceding this book, Smolin writes that no fundamental discoveries had been made in physics–a sudden stoppage in progress that had been flowing since the early ‘s.

If we look back at Einstein when tbe was working on General Relativity, he lhysics the physics: So there is no reason to expect that string theory will either. The book is essentially a critique of string theory, although that really only provides a framework for a broader and deeper discussion of the state of physics and science, the philosophy of troubls and problems in the academia.

The Trouble With Physics

They do not necessarily have strong technical skills, but they are visionaries, and are not willing to “follow the crowd”. If anything, the practice in non-string approaches to quantum gravity is to underclaim, as this is more the style in mathematics and in European science, where most workers come from. Open Preview See a Problem? Water is not chiral. One example of what I mean is the following: Perhaps you can convince Bigfoot to take a few of these frightening men along with him on his journey back to the Landscape.

The Trouble With Physics | Not Even Wrong

My book arose out of such a re-examination and its value, for me, is that it contains proposals for what are the wrong ideas that took such a promising idea to its present crisis. Have you met him? But science is unique in that it eventually self-corrects, it just takes longer than it should sometimes. If string theorists had any rationality they would take such facts as at least a serious alternative to string! I find the sociology of science rather interesting. In other words, rather than picking some background spacetime and studying the propagation of strings or whateverLQG is formulated without reference to any specific background.

Its a massive undertaking to write something that by many would be seen as “anti” to the scientific community of which Smolin himself is a part of.

The scenario of many unobserved universes plays the same logical role as the scenario of lef intelligent designer. There’s so much interesting material that it’s easy to miss many of the best bits first time around! Why has physics got ttrouble into this mess?

Just a moment while we sign you in to your Goodreads account. Moshe, LQG is a modelling process, not a speculation. It is perhaps not surprising that there has been a backlash against string theory.

However, at times it may feel that the themes of the book are not quite connected, or they are discussed only superficially. He encourages physicists to investigate new alternatives and highlights several young physicists whose work he finds promising.

Physicists like to take about what happens at different “scales” – the scale of subatomic particles, the scale of molecules, the scale of planets, etc. Actually this goal must be attributed to Newton and all his followers. I am about to chill on a CA beach right now Two issues are being confused here.

The Trouble with Physics: The Rise of String Theory, the Fall of a Science and What Comes Next

Building up on his examination of the current situation, Lee argues that the way scientific programs and researchers are supported today is inefficient under the present circumstances.

Hence it’s extremely hard to disprove it. And this continues to be my biggest beef with string theory, I think. Not only that, but there is some odd data coming from the Pioneer 10 and 11 probes. Uncle Al – Lumo, as usual, is not quite correct. One can then argue that any operator product in the kinematical Hilbert space that is defined re the limit of a regularization procedure, such that it gives rise to a well defined operator on the Hilbert space of diffeomorphism invariant states, has no uv divergences.

But no one behaved badly. The idea is that in a curved space, for any path that starts out somewhere and comes back to the same point a loopone can imagine moving along the path while carrying a set of vectors, and always keeping the new vectors parallel to older ones as one moves along. This book begins by reviewing the landscape of physics before the rise of string theory, and then goes into some detail about string theory itself. Smolin contends in a chapter on the “sociology” of the field that theorists have “groupthink,” and look to thought leaders for approval.

But this is not a good model for a fundamental theory, for we accept this situation by casting the standard model as an effective field theory.

Smolin writes that there are two types of scientists; craftsmen and seers.

I went through it and I was amazed to see the extend that some disagreements can take and the way that people, affiliated with high profile institutions, behave when they should be models for the rest of the community and their students. However, it can be shown that problems worked in both theories yield different results. The result gives general relativity without a metric ie, background troublw.
