Sabine Hossenfelder: This is what’s wrong with physics.

#Astrophysics #Physics #SabineHossenfelder
Dr Sabine Hossenfelder is a theoretical physicist and a fierce defender of the essence of science. She is a Champion of erradicating nonsensical Ideas. She is passionate about outreaxh and communication of advanced scientific ideas “without the gobbledygook” on her YouTube channel @SabineHossenfelder
She is a Research Fellow at the Frankfurt Institute for Advanced Studies where she works on physics beyond the standard model, phenomenological quantum gravity, and modifications of general relativity. Hossenfelder has also been researching since at least 2008 on how technology is changing researchers' ability to publicize, discuss, or publish their research, when she co-organized the Science in the 21st Century workshop.

She has written more than 70 research articles, mostly dedicated to quantum gravity and physics beyond the standard model. Her research is or has been supported by the Foundational Questions Institute, the German Research Foundation, the Swedish Research Foundation, and the Franklin Fetzer Fund.

In her channel @Sabine Hossenfelder = "Science without the gobbledygook," Sabine talks straight about science: No hype, no spin, no tip-toeing around inconvenient truths. New video each Saturday.

Hossenfelder's first book, Lost in Math: How Beauty Leads Physics Astray, released in June 2018. A review in Nature described it as "provocative", and Frank Wilczek recommended it as an "intensely personal and intellectually hard-edged" book, even though he disagreed with it "on many points" (Basic Books, 2018)

00:00:00 Intro
00:00:59 Is philosophy dangerous for physicists?
00:02:22 Is there more "hype" in physics than in other sciences?
00:04:23 What do you think of the optimism aimed at future experiments such as LISA?
00:07:42 How did you arrive at the conclusions you did on your most recent paper without knowing initial conditions?
00:11:30 What if James Cleark Maxwell could tweet? Would he have been discredited?
00:13:42 Why is there so much attention on UFOs ? Is it just bayesian inference?
00:16:00 What visual evidence counts as data? Especially where UFOs are concerned?
00:17:30 Can you reiterate your thoughts on the mulitiverse theory and its' relationship to dogma?
00:24:15 What do you think of string theories claims to explain so much with so little evidence, leaving it to others to measure initial and boundary conditions?
00:29:20 You're a critic of big experiments. Where do you think physics is going/should go?
00:35:40 How did you become a youtube science star?
59:50:00 What do you think of the doctrine of "fine-tuning" of the Universe?

I'm a physicist... published in Phys rev Letters but "dropped" out of science work by the random decisions life imposes on us.
Sabine is one of my favorite tools that teleports me back to the alternate universe where I'm doing physics again.
I love it!
Thanks both for the discussions!

Sabine has such a clear understanding of her field that even people with rudimentary knowledge can get something out of each talk. I sure do.

[DrBrianKeating]

What is the most inconvenient and/or inconsistent aspect of modern science?

[JCO]

The YouTube algorithm is doing it for me. Every video with Sabine is recommended and I dutifully watch them all. Perhaps that I'm subscribed to her channel helps.

[guiart]

Everybody talks about what they think is interesting…Sabine actually gets it across in the most understandable way to my layman’s understanding…

[David-dibo]

So excited for this! Sabine is a rockstar!

Maxwell was operating in a world where the most successful physical theory was mechanics. In mechanics we also have forces, so that seems to have some commonality with what he was trying to do. So, he visualized a mechanical system, and originally had 20 equations. There is a good description in a biography of Maxwell titled "The Man Who Changed Everything: The Life of James Clerk Maxwell" by Basil Mahon. In it he describes the process that Maxwell went through. It might be useful for Brian and Sabine to read the book and then discuss the question Brian asks.

What I like about Sabine's videos is that they seem incredibly well researched... so much information is packed & explained that it feels like a mini-masterclass on a subject! I also like how she calls it like she sees it, without too much tip-toeing, I believe Eric Weinstein jokingly calls her a curmudgeon, but too me she comes across as very likeable and authentic!

BTW, I find the Rob Reid (After-On) podcast also condenses a tremendous amount of well researched material in a short amount of time.

[dennistucker]

Love listening in on conversations like this. I really enjoy great minds that are well grounded in good communication skills.

[spaceinyourface]

I don't really notice any inconsistencies, ,I just enjoy watching you folks discussing the big ideas. When new answer's come our way it's only because you lot put the effort & time in to thrash it out. Never stop.

[timjohnson]

Great job on the interviewing and video editing! Also great job on the questions! Most interviews have what seems like a couple soft-pitch / canned questions, but it really felt like all you did your homework and all your questions were well thought out.

[gustavderkits]

The superfluid dark matter hypothesis is the most interesting idea in cosmology for a long time. It deserves more attention. I’m very happy that Dr. Hossenfelder is working on it.
On string theory, it is beautiful math, but I count no predictions in the usual sense of that word, only post-hoc claims. String theory “explains” everything after someone has discovered it. I recall Dr. Kaku’s pronouncements during the Fukushima nuclear disaster. I was distressed by his claims of expertise so far beyond his realm of confidence. The most outstanding contribution of Dr. Kaku so far is his magnificent hair.

Great episode. It’s my first time to watch your channel though not the first time I’ve watched the good Dr. Sabine H. I am a fan of hers and watch not only her YouTube channel but have seen her other appearances that’ve been televised here as well. Physics in all its forms fascinate me and I love her no nonsense approach. Great interview.

Philosophy is the search for questions that have no answers. It helps to define the boundaries of science. Science is the search for self constancy in measurements. Self consistency is best described by mathematics. Mathematics is the search for self consistency in abstract symbols. Self consistency is defined by language. Language is the device of communication. Language is defined by the community.

It is not 'initial conditions' that constrain a system's behaviour or evolution, but 'boundary conditions' instead. This means that you are not limited by what the system's status or configuration was at an imaginary 'first moment' - any constraints would do.

[Alexander_Sannikov]

watching sabine talking nonscripted is so cool. she should do more interviews. I particularly want to see her on sean carroll's podcast because their views will clash, but i'm sure their discussion will be thrilling.

[trucid]

I've been following Sabine's work on superdeterminism for years and I'm so excited to hear about the new paper she has on it. Can't wait!

[Thomas-gk]

Thank you for this interesting talk. Very nice, to see Dr.Hossenfelder so enthused and emotional talking about her work about superfluid dark matter. I wish, she finds some specialists on condensed matter, to help her with this project. I'm sorry, I'm just craftsman.

I feel magnetism and electromagnetism play such a crucial aspect of the cosmos. It's really facinating how so many properties with-in Nature, differences seem to be a key factor in keeping dynamic systems functioning. High pressure/low pressure, hot/cold temp, different densities, static electric charges/discharges, electromagnetism north/south poles, different velocity/angular momentum, layers between different regions such as, land, water, air, edge of atmosphere, space, the different regions in space with different particle density, creating bubbles/membrane layers, cloud regions, nebula's/ Galaxy's, Galaxy clusters, less dense voids regions of space. All of these things are basic differences but create a way for the dynamic engine with-in Nature to continue flowing and operating to create and convert energy. How a battery 🔋 transfers + charges through a membrane layer to a - charged side. Like how regions of high/low pressure and temperature 🌡️differences create winds. Transfer that into water or planets core and add density. It creates either ocean currents and flow or planetary convection geothermal activity.

The interviewer is doing wayyy too much filibustering and inserting personal opinions. 33:20 was particularly bad, cutting her off mid opinion to give his own and then moving the topic.. and the worst part is that he already made his point in the long winded / loaded question she was responding to, on the "bigger is better" spending philosophy in physics.... Either way I'm glad that Sabine is rational without all the overintellectualizing that goes on in this field, she really reigns in her views quickly and rationally.
