Spacetime Unified: Physics for Everyone, Origins Lecture 6

53K views · 1w ago · 1:22:25

Guest: Spacetime Unified

The culmination of classical physics. The unification of Electricity and Magnetism, combined with the insights of Galileo, led inevitably to a completely new conception of space & time, and to E=mc^2. Everything we have discussed in these lectures so far has brought us to this, the first 20th century revolution in physics. And that is the way it should be, but it is most definitely NOT the way it is normally taught in physics classes.

AI wonders and nightmares, Dark Matter discovered?, and fake science news? What's new in Science.

There has been a lot of doom and gloom combined with excitement, if that is possible, about AI in the science news lately. Sabine and I tried to deconstruct the hype associated with the highly touted Open AI solution of one of the Millennium Problems in Mathematics, as well as explore the real concerns and imaginary concerns associated with both the recent Open AI agent hacking of Huggy Face, and the blog post by the CEO of Anthopic arguing for a pause in AI development…

Searching for Aliens: The wrong way?, with John Gertz.

Guest: John Gertz

An in-depth discussion with the former Chair of the Board of SETI & author of Reinventing SETI about the futility of searching for signals of extraterrestrial intelligence in other star systems. John Gertz is a Renaissance Man. One might think that the President of Zorro Productions might be the last person to talk with about the Search for Extraterrestrial Intelligence (SETI), and the last person to chair SETI’s governing board.

Physics for Everyone, #4. The Beating Heart of Modern Physics: The Dog Who Didn't Bark in the Night.

Symmetry in physics is more powerful and nuanced than it is in art. Almost all of modern physics comes down to exploring symmetry, and, often even more important, its absence. This lecture, recorded before lecture 5, which was released a month ago, actually more naturally follows it, which is why releasing it after lecture 5, while unintended, actually makes sense.

What's New in Science with Sabine and Lawrence | Cosmic oddities, Quantum Batteries, and more

Sabine and I once again explore fascinating claims about the universe, some of which may be right, and some new proposed experiments that could shed light on current mysteries, or produce new ones. Happy August! . Heading back to North America as we just concluded our Origin Project Adventure to Cyrpus and Greece, where we felt the heat, and avoided some wildfires while having some amazing positive experiences as well with an amazing group of 26 travelers.

Considering supporting them at Their original escape plan was foiled when the airport was bombed just before their planned departure. Because Claire lives in Frances the older boy had reached out to her for help, and she sent out a call to her followers to provide financial assistance to help the family.

Physics for Everyone 5: The Unification that Changed the World

11K views · 3mo ago · 1:54:56

The development of the modern understanding of electricity and magnetism not only changed the modern world, it guided our understanding of fundamental physics. I began this lecture by saying I was daunted by what I was about to talk about. There are several reasons for this.

What's New in Science: Cosmic Surprises, Newton Supreme, A New Collider, and Feynman Dines Out?

I think this was one of my most enjoyable dialogues in our What’s new series. Maybe Sabine and I are getting more used to each other’s cadence and interests or maybe it was the subject matter. Either way, I think you will find this to be a fascinating and provocative discussion of science at the forefront, and at the not-so-forefront, because that science is interesting too!

Origins Podcast: Moral Economics with Nobel Laureate Alvin Roth: From Prostitution to Kidney Markets

3.4K views · 5mo ago · 1:41:49

Guest: Nobel Laureate Alvin Roth

Roth’s new book, which is fantastic, and comes out the same day this podcast is released deals with issues that often raise the public’s ire, from legalizing prostitution, to assisted suicide, and finally to a rational market for kidney transplants. For example, everywhere there is good date, legalizing prostitution reduces not only incidents of sexually transmitted disease, but also violent sexual assaults. It may also combat illegal human trafficking.

Consider supporting the podcast and the Origins Project Foundation at I’m back with my friend and colleague Sabine Hossenfelder for another episode of “What’s New in Science”. Spending time with Sabine was a nice chance to step away from my physics lecture series for a bit. I know many of you have been enjoying the lectures, so don’t worry, they’ll be back soon.

Motion, from Galileo to Dark Mysteries. Lecture 3 in the Origins Podcast Series on Physics

8.3K views · 6mo ago · 1:03:22

We usually begin the study of physics with a discussion of motion, not because it is easy, or because the modern understanding of motion began with Galileo hundreds of years ago. Rather, Galileo’s groundbreaking work provides a paradigm to understand how physics is done today.

Alcoholism is a scourge on modern society. Every year, 178,000 American die from alcohol abuse, and it has been estimated that over 200 billion dollars is lost from the US economy due to alcoholism, includingcosts of health care, lost productivity, and costs of crime enforcement. Given this immense social cost, it is equally amazing that there is no widely accepted cure.

Clarke put it. In that spirit, the way we get closest to “magic” in physics is not by memorizing more facts or equations, but by learning a few mental tools that help us see through the illusion of complexity by extracting the wheat from the chaff.
