Physicists need to learn from their mistakes | Sabine Hossenfelder

Sabine Hossenfelder explains why physicists have mistakes to learn from.

In this interview, Sabine Hossenfelder details why the foundations of physics has not made any progress, why physicists need to learn from their mistakes, why they're practicing poor science and investigates the inconsistencies in some of our preassumed theories of physics.

She is wonderful. I am in awe of her intellect and her dedication to share, with us, the results of her prodigious effort.

14:02 “I think that I should do something to spread the knowledge” and boy are we fortunate that is so!

[makingnoises]

I deeply appreciate Sabine's candor and straightforwardness, as well as her dedication to genuinely advancing scientific understanding. It's often the case that science communicators will use their knowledge and the opacity of their jargon to put forward ideas without addressing their shortcomings or acknowledging their assumptions, and it's led to a gamut of charlatans who posit ridiculous claims using the same obfuscatory language. It's deeply refreshing to hear from someone who is genuinely passionate about the topic and about spreading understanding.

Dr. Sabine Hossenfelder is an amazing person. Her views are brave. More thinkers like her are needed. Hopefully she is getting the required encouragement to continue.

I love this woman, she needs a larger audience

[johnmccabe]

Thank the heavens for you Sabine and other scientists and staff that make these regular contributions of sciences to us the semi scientific literate public.

[justinrahn]

Doctor H reminds us that peer review is an essential part of the scientific method.
I enjoy watching her cut lofty theories down.

[antonystringfellow]

I hope that one day, in the not too distant future, we will be treated to a discussion between Sabine and Sean Carroll.
That would be something!

[jibberer]

I love listening to Sabine, she's totally awesome and really engaging. She has an uncanny knack of simplifying very complex topics in a way that doesn't assume the audience are idiots.

[LRRPF]

I commend Dr. Hossenfelder for her critical outlook that seeks to learn from the mistakes of physics, of which there have been many.

"Bell always presented his result in combination with the EPR argument, which
shows that the mere assumption of locality, combined with the perfect correlation
when the directions of measurement (or questions) are the same, implies the existence
of the supposedly “impossible” hidden variables. So for Bell, his result, combined
with the EPR result was not a “no hidden variables theorem”, but a nonlocality
theorem, the result on the impossibility of hidden variables being only one step in a
two-step argument.
"Viewing Bell’s argument as a refutation of hidden variables theories
is doubly mistaken: first because, combined with
EPR, Bell proves nonlocality; and second because the de Broglie–Bohm theory,
which Bell explained and defended all his life, proves that a hidden variables theory
is actually possible."

Sabine is spot on. I was in a colloquium in Austin in the mid 1990s. The speaker had expounded some aspect of Quantum Gravity. Then Steven Weinberg asked him: "What makes you think there is a theory of Quantum Gravity?" I don't remember the speaker's response, but I do remember Weinberg's elaboration. Weinberg pointed out that every theory is an "effective theory" with a range of validity or usefulness for the problem at hand. We are trying to work with an underlying reality, but it is the "effective theory" that we work with, and there is no reason to expect that we can always reconcile the effective theories with each other. We may just have to choose what works in a given regime.

[Xcalator]

Sabine is awsome!! I admire her more and more.

[Wacoald]

This interviewer is great, short and to the point!

[duderama]

I love the way she's willing to discuss the dark matters of physics.

[elultimopujilense]

Honest, humble and unbiased. Dr. Sabine is a real scientist.

[gregorypym]

Superb as always. Thank you so much for making it understandable to ordinary folk like me.

[nalathekitten]

I love her so much
She gets straight to the point and is very clear on current situation with quantum mechanics or physics world. ✋🏻🙏🏻😍

"Tell us something about your last calculation" … I love this question. And I love Sabine's response …
