LEE SMOLIN THE TROUBLE WITH PHYSICS PDF

In this groundbreaking book, the renowned theoretical physicist Lee Smolin argues that physics — the basis for all other sciences — has lost its way. For more. The Trouble with Physics: The Rise of String Theory, the Fall of a Science, and What Comes Next. Lee Smolin, Author. Houghton Mifflin $ Abstract. Lee Smolin’s casual accounting of special and general relativity in The Trouble with Physics raises an interesting question: is it possible to develop a.

And we fool ourselves not only individually but en masse. Suffering from groupthink, careerists, and ladder-climbers, just like everywhere I ever worked. And this continues to be my biggest beef with string theory, I think. I am truble even sure it was already sent out. LQG is far smaller and younger then String theory, whether or not we are heading towards a first revolution the next few years will show.

August 30, at 9: I do not even want to imagine what Nietzsche had made out of this drive into self delusion and science-as-cult beyond its empirist tradition.

So I am not willing to engage with people who are not willing to recognize good faith and respond in kind. Smolin smloin purportedly tried to be a bridge between the string theorists and the ever-shrinking non-stringers, but points out through various articles, blogs, message boards, and others how vitriolic the string theorists can be.

I found that section at the end more interesting. Risk Management, being in the bush is like playing poker. Reduce the gravity term and make the perfect sponge cake? To be clear, the scientists working on Wifh and other non-stringy approaches to quantum gravity are not crackpots, but honest researchers tackling a very difficult problem.

Now guess who discovered the Virasoro-like extension of the diffeomorphism algebra in higher dimensions. Nevertheless, here it is.

The Trouble with Physics – Wikipedia

But the main focus of his smollin isn’t that string theory has failed still too early to say that for sure I guessbut rather criticizing how it has monopolized theoretical trkuble in terms of grants, post-doc positions, etc. Modern physics hates experimentation. Smolin does have other books which do just that though, such as his book The Life of the Cosmos, which I quite pysics reading now. As far as I can tell, both string theory and LQG and every other approach to quantizing gravity are in the position toruble not making a single verifiable prediction that, if contradicted by experiment, would falsify the theory.

But it seems the prevailing atmosphere I encountered 20 years later in theoretical physics wasn’t all that different. My imagination from quantum mechanism theory and the universe spreads. He is extremely worried about the fact that it has become difficult for young researchers to get money to pursue novel ideas, with most funding concentrated on a small number of mainstream projects which are regarded as “safe”.

And again let us not get emotional there are some string troubke which are to the far left and some to the far right of the ‘political’ spectrum 3 Dark matter, dark energy and black holes, have not even been clearly defined. A group of young theorists has begun to develop exciting ideas that, unlike string theory, are testable. Just like an adolescent, I wanted to be accepted by those who were the most influential in my little circle.

To me, this is quite interesting, as Lee Smolin is not subtle in his discussion about the physics community. They define a scattering amplitude in terms of a spin foam model.

It’s tough to do that though since the theory is so entrenched in the elite corridors of academia. For long centuries during which our understanding of the world we live in has progressed tremendously. Back to the white board. Nobel prizes require verification by experiment, which is not possible with most of string theory.

I thought Physics wasn’t able to pickup girls anymore. On this evaporation rrouble, trying to catch your serious side for a moment. The unexplained constantness of the speed of light in a vacuum was Einsteins starting point, led I am not quite informed, but I do not see that there are any compareable fundamental facts pointing beyond the existing models today. I find the sociology of science rather interesting. What about general relativity?

Thanks for this review, Sean. The public can be excused for thinking that ST researchers are in it for the money, that it has been taken for a ride.

troube These are not the same thing; I know plenty of people, for example, who exist eith are unique and well-defined yet very ill-behaved.

In Brazilresearch in physics and astrophysics has grown tremedously in the past 10 years or so. In fact, we can’t conceive of any experiment that would. That said, it is overdue that the String community, especially the high priests and their arrogent followers, get a kick in the butt.

So there is not yet a claim that LQG passes all physica tests for a good quantum theory of gravity. Recasting Morse theory, Atiyah-Singer, Donaldson theory via duality — that would be enough. An interesting and well-written book. Alternatively, to show that 2 is true we should find a new way to construct non-supersymmetric string theories.

Consequently, I felt this part of the book a bit too long for this layperson’s taste. Dec 29, Marcus rated it it was amazing Shelves: But the most important point he makes is that string theory has never made any testable predictions, and phyxics some string theorists are even saying maybe we should redefine “science” so that it doesn’t have to be testable! August 30, at Mar 19, notgettingenough rated it really liked it Shelves: Is the notion of a field an oversimplication?
