Don't bother, just pick up a GR textbook like Hartle or Schutz. Those books teach the math as they go.

I second the suggestion for Sean Carroll's Something Deeply Hidden. Sure, much of it argues for a specific theory (many worlds), but the introductory chapters give a very good layperson's introduction to the motivations and evidence for QM.

The problem is quite old and this article does not address the newer possible solutions or arguments. If you want a more modern and complete review the situation in a very readable form I recommend Something Deeply Hidden by Sean Carroll. He is advocating for his position and solution, but he addresses the whole argument fairly.

Thorne (+Misner and Wheeler's) Gravitation is by far my favorite.

More elegant but not necessarily better

You might find this book interesting: Something Deeply Hidden.

There's a strong argument that there's no "collapse of the wave-function" into a particle, that it is in fact fundamentally a wave in the first place. The uncertainty principle is a manifestation of this wave nature.

So, you have no response? You don't need to take my word for it, I highly recommend you read Lori Garver's book escaping gravity, she details how congress continually worked against presidential directives to lower cost to orbit in favor of pursing more pork projects for their district.

Former Deputy Administrator of NASA (2009-2013) during the Obama Administration, controversial (but vindicated now) for her efforts to push NASA to pursue fixed cost commercial procurement programs, like Commercial Resupply Services and Commercial Crew. She was a key supporter of SpaceX early on at a time when there were a lot of skeptics about it at the time.

Anyhow, she has a new book out this week about the whole thing. The OP was clearly inspired by the new Off Nominal podcast with her earlier today.

I think it comes out on June 21^st.

Okay thats fair.; Exact category is often debated.

The less debated fields don't have a replication crisis per se: They have a falsifiability crisis.

Lost in Math: How Beauty Leads Physics Astray

The multiverse is pretty widely accepted among theoretical physicists, and does involve vast numbers of splitting timelines. You can read more in Sean Carroll's recent book, "Something Deeply Hidden".

So yeah I would double what /u/Rare-Dragonfly7652 says, each can potentially manifest the same SP in different timelines. However, you have to keep in mind that you may be changing their personality to force someone to be with you, and you may not end up liking that.

I still have this book sitting in my room. Maybe I should give it another read so I can laugh at the stupid shit I used to want to believe in.

Since your objective seens to be general relativity, I suggest https://www.amazon.com.br/Gravitation-Charles-W-Misner/dp/0691177791, but if you're interested in a more mathematicaly rigorous approach, or need to study it deeper, like tensor fields, first study advanced linear algebra, real analysis and differential geometry, than I suggest reading using the book you're already familiar on advanced linear algebra or differential geometry, most probably one of then will cover tensor calculus.

Kerr. The ergosphere is actually important to the story. The concept and basic story was co-written by Kip Thorne. Yes, THAT Kip Thorne.

A very good book on this.

'The Hunt for Zero Point: Inside the Classified World of Antigravity Technology 2003

This riveting work of investigative reporting and history exposes classified government projects to build gravity-defying aircraft--which have an uncanny resemblance to flying saucers.

The atomic bomb was not the only project to occupy government scientists in the 1940s. Antigravity technology, originally spearheaded by scientists in Nazi Germany, was another high priority, one that still may be in effect today. Now for the first time, a reporter with an unprecedented access to key sources in the intelligence and military communities reveals suppressed evidence that tells the story of a quest for a discovery that could prove as powerful as the A-bomb.

The Hunt for Zero Point explores the scientific speculation that a "zero point" of gravity exists in the universe and can be replicated here on Earth. The pressure to be the first nation to harness gravity is immense, as it means having the ability to build military planes of unlimited speed and range, along with the most deadly weaponry the world has ever seen. The ideal shape for a gravity-defying vehicle happens to be a perfect disk, making antigravity tests a possible explanation for the numerous UFO sightings of the past 50 years.

Chronicling the origins of antigravity research in the world's most advanced research facility, which was operated by the Third Reich during World War II, The Hunt for Zero Point traces U.S. involvement in the project, beginning with the recruitment of former Nazi scientists after the war. Drawn from interviews with those involved with the research and who visited labs in Europe and the United States, The Hunt for Zero Point journeys to the heart of the twentieth century's most puzzling unexplained phenomena.

I don't know about apps per se, doesn't Audible have one? Anyway, I am listening to Reality Is Not What It Seems by Carlo Rivello - it's about gravity loops and the narration is first rate. You might like that.

Andy Weir's recent Project Hail Mary spins slower than the speed of light travel exactly like this.

Universe may be big, but (actually) not so much for the ones traveling. It's like it's calling to us..... dun dun dunnn.

If you're into GR and a fair bit studious you can learn more here.

If you're into my worst book spoiler ever up there you could check out Weir's book, >!but it's definitely about something else!<. It oozes Weir if you're into that style. :)

I just read this book. Written by a guy who was editor of Jane's Defense Weekly for 12 years. He goes on a hunt around the world in search of this weird freaky zero point energy. Which can mean anti-grav propulsion among other things. The nazis had some very weird cutting edge science going on towards the end of WW2. The author of the book visits the son on an unconventional scientist German guy who the American military scoffed up from the nazis. Einsteinian stuff. Quantum physics stuff.

The author also visited another unconventional guy in Vancouver John Hutchison - who was doing remarkable things in his apartment. Interesting enough to get visits from American military.

Anti-gravity wouldn’t surprise me, they were working on it in the late 50’s. Problem is, even Einstein never really understood gravity. A decent read on the research:

>Personally I've been very happy with this one, but I'm not terribly familiar with the comparable books you could choose instead.

The one my intro GR course used was the intro to GR book by Schutz. I liked it, but from what my instructor told us it is much less rigorous than the one you linked.

Ok that's a fair tldr. I think it's completely solvable with a post scarcity society. There are probably dozens of solutions I'm too dumb to think up but could be found and implemented eventually. But that's beside the point.

If you told me my choices were tyranny that will almost certainly never end, or death that can never ever be reversed under any circumstances, it's not even close. Give me life and a chance. And that's the point, life gives chances. Death removes chances.

Biochemistry sounds awesome! Good luck with that. And with QM I loved Sean Carroll's book Something Deeply Hidden . He has an audio format if you prefer that. He's a big proponent of Everett's MWI.

I'm currently trying to improve my understanding of string theory. As I understand it most physicists pretty much agree now that string theory isn't correct, but oddly enough the math gives pretty accurate predictions that line up with what we see.

Sean Carroll has a recent book on it. Does a good job of explaining things on a level most people can udnerstand.

Just want to comment, that physics dont have to be beautiful minimalistic which is also discussed in the science community and also found its way into popular books like Lost in Math: How Beauty Leads Physics Astray.

Imo it is quite unscientific to rule out solution which are not "mathematically beautiful" or "simple and elegant". Or not searching for solutions which do not meet this criterias.

This book is an interesting discussion of the various interpretations.

https://www.amazon.com/Something-Deeply-Hidden-Emergence-Spacetime/dp/1524743011

The author's opinion is that the Many Worlds Interpretation is our best bet, primarily because it's the simplest. You don't need to add anything to it.... no special observers, no hidden variables... it's just the wave function and schrodinger's equation. I tend to agree.

One, I'm not attacking anyone and particularly not the youngsters. I'm trying to speed their progress. I provided plenty of directions on what they should be reading. Go up to my initial comment here. I didn't dismiss Graham completely; instead I suggested people read Zhang first for some proper framework. In particular, his approach is compatible with efficient markets so the premiums are there to be earned by everyone. (More broadly I like to live with an abundance mindset. It's not always zero sum, mi amigo, especially since we are not talking about alpha here.)

You present yourself as a thinking man and professional, but sometimes I wonder if you have a reading comprehension problem or alternatively your reading ability is fine but you are so resistant to the viewpoints of others that you fail to understand them properly before you lash out. I'm no psychologist so I will leave that to your therapist.

Second, go knock yourself out with his lectures (https://www.amazon.com/Feynman-Lectures-Physics-boxed-set/dp/0465023827/) . Not a real test since you are smarter than the average /r/investing bear but give it an honest effort and report back in a month.

These type of craft have been around for decades in the black world. It’s called electromagnetic-gravitics, or EMGs. Reducing the mass of a craft increases both its fuel efficiency and its speed, as force = mass x acceleration. Think of it as creating a bubble of your own local space-time. You create the bubble around your craft and then control the direction of that bubble and fly around like Glenda the good witch of the north in the wizard of oz. Or more accurately, as it was done in the ‘80’s movie, “Explorers”, staring Ethan Hawke, River Phoenix, and Jason Presson. https://en.m.wikipedia.org/wiki/Explorers_(film)

For more on this subject I suggest reading, “The Hunt for Zero Point”, by Nick Cook. https://www.amazon.com/Hunt-Zero-Point-Classified-Antigravity/dp/0767906284

There have been other types of craft similar to this postulated. Dr. Paul LaViolette has claimed for years that a different type of mass reduction technology was/is employed on the B2 bomber. One that uses plasma induction around the crafts body to reduce its air resistance.
