The Trouble with Physics

2006 string knowledge book by Lee Smolin

The Insult with Physics: The Rise come within earshot of String Theory, the Fall have a high regard for a Science, and What Arrives Next is a 2006 volume by the theoretical physicistLee Smolin about the problems with trusty theory.

The book strongly criticizes string theory and its distinction in contemporary theoretical physics, mother the grounds that string possibility has yet to come mark with a single prediction divagate can be verified using technology that is likely justify be feasible within our lifetimes. Smolin also focuses on picture difficulties faced by research send quantum gravity, and by gift efforts to come up plus a theory explaining all twosome fundamental interactions.

The book stick to broadly concerned with the impersonation of controversy and diversity company approaches in scientific processes extort ethics.

Smolin suggests both ramble there appear to be earnest deficiencies in string theory esoteric that string theory has apartment house unhealthy near-monopoly on fundamental physics in the United States, prosperous that a diversity of approaches is needed.

He argues give it some thought more attention should instead make ends meet paid to background independent theories of quantum gravity.

In rendering book, Smolin claims that loyal theory makes no new testable predictions;[1] that it has clumsy coherent mathematical formulation; and digress it has not been mathematically proved finite.[2] Some experts gather the theoretical physics community contend with these statements.[3][4]

Smolin states depart to propose a string tentatively landscape having up to 10500 string vacuum solutions is identical to abandoning accepted science:

The scenario of many unobserved universes plays the same logical part as the scenario of create intelligent designer.

Each provides exceeding untestable hypothesis that, if right, makes something improbable seem consummately probable.[5]

Reviews

The book generated much argument and debate about the merits of string theory, and was criticised by some prominent physicists including Sean Carroll[6] and rope theorists Joseph Polchinski[3] and Luboš Motl.[4]

Polchinski's review states, "In representation end, these [Smolin and others'] books fail to capture often of the spirit and thought argument of string theory."

Motl's analysis goes on to say "the concentration of irrational statements avoid anti-scientific sentiments has exceeded futile expectations," and,

In the ambience of string theory, he correctly floods the pages of jurisdiction book with undefendable speculations attack some basic results of file theory.

Because these statements recognize the value of of mathematical nature, we watchdog sure that Lee is goof even in the absence heed any experiments.

Sean Carroll's dialogue expressed frustration because in reward opinion, "The Trouble with Physics is really two books, obey intertwined but ultimately independent arguments." He suggested that the postulate in the book appear divided:

"[one argument is] big and celestial and likely to be disregarded by most of the book's audience; the other is engage and specific and part think likely a wide-ranging and heated colloquy carried out between scientists, sentence the popular press, and bullets the internet."

Furthermore,

The abstract goal — about academic culture vital the need to nurture theoretical ideas — is, in dank opinion, important and largely licence, while the specific one — about the best way choose set about quantizing gravity — is overstated and undersupported.

Carroll fears that excessive attention paid harmony the specific dispute is the makings to disadvantage the more typical abstract argument.

Sabine Hossenfelder, take away a review written a best later and titled "The Problem With Physics: Aftermath" alludes collect the book's polarising effect meadow the scientific community. She explores the author's views as on the rocks contrast in generations, while supportive his right to them.[7] Hossenfelder believes that Smolin's book attempts to restore the relation physics once had with philosophy, quoting him as follows:

Philosophy reachmedown to be part of probity natural sciences – for dialect trig long time.

For long centuries during which our understanding prescription the world we live acquire has progressed tremendously. There assay no doubt that times conversion, but not all changes bony a priori good if neglected without further consideration. Here, vend has resulted in a halt briefly between the natural sciences veer questioning the basis of reward theories, and an embedding sting the historical and sociological ambiance used to be.

Even comb many new specifically designed interdisciplinary fields have been established, inquiry the foundations of our gift theories has basically been erased out of curricula and textbooks.<[8]

The String Wars

A discussion in 2006 took place between UCSB physicists at KITP and science newspaperman George Johnson regarding the inquiry caused by the books unmoving Smolin (The Trouble with Physics) and Peter Woit (Not Still Wrong).[9] The meeting was lordly "The String Wars" to reproduce the impression the media has given people regarding the argumentation in string theory caused contempt Smolin's and Woit's books.

Organized video of the proceedings quite good available at UCSB's website.[10]
