Sometimes Ane Believe Inwards String Theory. Therefore Ane Wake Up.

They utter close me.

And I can’t blame them. Because cipher else is happening on this planet. There’s simply me in addition to my examine to convince physicists that beauty isn’t truth.

Yes, I know it’s non much of an insight that pretty ideas aren’t ever correct. That’s why I objected when my editor suggested I championship my book “Why Beauty isn’t Truth.” Because, duh, it’s been said earlier in addition to if I wanted to live on stale I could convey written close how we’re all made of stardust, aah-choir, chimes, fade in addition to cut.

Nature has no obligation to live on pretty, that much is sure. But the truth seems difficult to swallow. “Certainly she doesn’t hateful that,” they say. Or “She doesn’t know what she’s doing.” Then they explicate things to me. Because sure as shooting I didn’t hateful to tell that much of what goes on inwards the foundations of physics these days is a waste materials of time, did I? And fifty-fifty if, could I delight non create this publicly, because around people convey to earn a living from it.

They are “good friends,” you lot see? Good friends who desire me to believe what they believe. Because believing has bettered their lives.

And certainly I tin live on fixed! It’s simply that I haven’t yet seen the elegance of string theory in addition to supersymmetry. Don’t I know that elegance is a sign of all successful theories? It must live on that I haven’t understood how beauty has been such a groovy conduct for physicists inwards the past. Think of Einstein in addition to Dirac and, erm, in that place must convey been others, right? Or maybe it’s that I haven’t yet grasped that pretty, natural theories are hence much better. Except perchance for the cosmological constant, which isn’t pretty. And the Higgs-mass. And, oh yeah, the axion. Almost forgot close that, sorry.

But it’s non that I don’t intend unified symmetry is a beautiful idea. It’s a shame, really, that nosotros convey these 3 unlike symmetries inwards particle physics. It would live on hence much nicer if nosotros could merge them to 1 large symmetry. Too bad that the laid about theories of unification led to the prediction of proton decay in addition to were ruled out. But in that place are a lot other beautiful unification ideas left to travel on. Not all is lost!

And it’s non that I don’t intend supersymmetry is elegant. It combines 2 unlike types of particles in addition to how cool is that? It has candidates for night matter. It alleviates the occupation amongst the cosmological constant. And it aids justice coupling unification. Or at to the lowest degree it did until LHC information interfered amongst our plans to prettify the laws of nature. Dang.

And it’s non that I don’t meet why string theory is appealing. I in 1 lawsuit laid out to larn a string theorist. I create non small-scale fry you. I ate my means through textbooks in addition to it was all totally amazing, how much you lot leave of absence from the rather uncomplicated stance that particles shouldn’t live on points but strings. Look how much consistency dictates you lot to create the theory. And banker's complaint how neatly it fits amongst all that nosotros already know.

But hence I got distracted past times a disturbing question: Do nosotros genuinely convey bear witness that elegance is a practiced conduct to the laws of nature?

The brief response is no, nosotros convey no evidence. The long response is inwards my book and, yes, I volition lift the-damned-book until everyone is sick of it. The summary is: Beautiful ideas sometimes work, sometimes they don’t. It’s simply that many physicists prefer to holler back the beautiful ideas which did work.

And non solely is in that place no historical bear witness that beauty in addition to elegance are practiced guides to observe right theories, in that place isn’t fifty-fifty a theory for why that should live on so. There’s no argue to intend that our feel of beauty has whatever relevance for discovering novel key laws of nature.

Sure, if you lot enquire those who believe inwards string theory in addition to supersymmetry in addition to inwards grand unification, they volition tell that of course of didactics they know in that place is no argue to believe a beautiful theory is to a greater extent than probable to live on correct. They yet travel on them anyway. Because what amend could they create amongst their lives? Or amongst their grants, respectively. And if you lot travel on it, you lot amend believe inwards it.

I consent, non all math is every bit beautiful in addition to non all math is every bit elegant. I yet convey to observe anyone, for example, who thinks Loop Quantum Gravity is to a greater extent than beautiful than string theory. And isn’t it interesting that nosotros portion this feel of what is in addition to isn’t beautiful? Shouldn’t it hateful something that hence many theoretical physicists concord beautiful math is better? Shouldn’t it hateful something that hence many people believe inwards the being of an omniscient god?

But scientific discipline isn’t close belief, it’s close facts, hence hither are the facts: This trust inwards beauty as a guide, it’s non working. There’s no bear witness for grand unification. There’s no bear witness for supersymmetry, no bear witness for axions, no bear witness for moduli, for WIMPs, or for dozens of other particles that were invented to prettify theories which travel simply fine without them. After decades of search, there’s no bear witness for whatever of these.

It’s non working. I know it hurts. But immediately delight wake up.

Let me assure you lot I ordinarily hateful what I tell in addition to know what I do. Could I live on wrong? Of course. Maybe tomorrow we’ll discovery supersymmetry. Not all is lost.

Outraged Nigh The Google Multifariousness Memo? One Desire You Lot To Mean Value Nigh It.

Chairs. [ Image: Verco ] That leaked internal memo from James Damore at Google ? The 1 that says 1 shouldn’t hold off employees inwards all professions to reverberate the demographics of the whole population? Well, that was a pretty dumb affair to write. But non because it’s wrong. Dumb is that Damore thought he could receive got a reasoned give-and-take close this. In the USA, out of all places. The version of Damore’s memo that get-go appeared on Gizmodo missed references together with images. But meanwhile, the multifariousness memo has its ain website together with it comes with links together with graphics. Damore’s strikes me equally a pamphlet produced past times a well-meaning, but also utterly clueless, immature white man. He didn’t deserve to get fired for this. He deserved mayhap a slap on the too-quickly typing fingers. But inwards his world, bespeak for give-and-take is evidently plenty to learn fired. I don’t commonly write close the underrepresentation of wo...

Dear Dr B: Should 1 Report String Theory?

Strings. [image: freeimages.com ] “Greetings doctor Hossenfelder! I am a Princeton physics major who regularly reads your wonderful blog. I lately came across a curious passage inwards Brian Greene’s introduction to a reprint edition of Einstein's Meaning of Relativity which claims that: “Superstring theory successfully merges full general relativity in addition to quantum mechanics [...] Moreover, non exclusively does superstring theory merge full general relativity with quantum mechanics, but it also has the capacity to comprehend — on an equal reason — the electromagnetic force, the weak force, in addition to the strong force. Within superstring theory, each of these forces is merely associated with a dissimilar vibrational designing of a string. And so, similar a guitar chord composed of 4 dissimilar notes, the 4 forces of nature are united inside the music of superstring theory. What’s more, the same goes for all of thing every bit well. The electron, the quarks,...

Particle Physics Right Away Belly Up

Particle physics. Artist’s impression. Professor Ben Allanach is a particle physicist at Cambridge University. He exactly wrote an promotion for my book that appeared on Aeon roughly days agone nether the championship “Going Nowhere Fast” . I’m kidding of course, Allanach’s essay has no relation to my book. At to the lowest degree non that I know of. But it’s non a coincidence he writes virtually the really problems that I also speak over inward my book . After all, the whole argue I wrote the mass was that this province of affairs was foreseeable: The Large Hadron Collider hasn’t institute prove for whatever novel particles likewise the Higgs-boson (at to the lowest degree non thence far), thence at i time particle physicists are at a loss for how to proceed. Even if they uncovering something inward the information that’s nonetheless to come, it is clear already that their predictions were wrong. Theory-development inward particle physics for the terminal forty years has work...
