The Origins Podcast with Lawrence Krauss

I remember when my friend, journalist Claire Berlinski, first contacted me about a tragic situation regarding a family trapped in Afghanistan after the Taliban takeover. She knew that I had helped a young girl interested in physics escape to the US to study years earlier and hoped that I might assist in this case. If ever one imagined a family appropriate to bring to safety, this would be the one. The mother was a women’s rights lawyer before the takeover, and the husband worked for a French firm. The Taliban had broken into the Bar Association Office and found records of lawyers, who were being sought for arrest. One older son, and five young daughters in danger of being married off if they were discovered.
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.
Claire contacted me because she knew I now lived in Canada, which has a well-established refugee program. In spite of this, for two years I was not able to find a single sponsoring agency who had a sufficiently large slot allocation to assist. Finally, after over a year, with five generous individuals who agreed to act as guarantors, Jewish Immigrant Aid Services in Toronto indicated they had the slots and would sponsor a refugee application for the family, provided we raised the necessary funds to guarantee support for family for their first year in Canada—a government requirement. After five months of fundraising, we achieved the goal, and the full application was submitted to the government of Canada.
I have always found it poetic that the organization in Canada that has been willing to help save this Muslim family is a Jewish organization. Perhaps, in the midst of all the horrible antisemitism that has blossomed in the world over the past years, this provide a useful example that religious differences need not always be a source of discord and hatred.
That was 18 months ago. In spite of having fulfilled at the requirements, the backlog of cases is such that we knew it could take up to two years for the application to be processed. In the interim the family was able to travel to Pakistan. But their visas have expired and Pakistan is now deporting Afghan refugees back to Afghanistan.
The family is in hiding in Pakistan, not able to leave their house. The girls are growing and one of them managed to learn enough English to get a prized scholarship to study online at a US university abroad, where she is studying psychology, as the law degree that she really wants is not available.
The family agreed to be interviewed for this podcast. Their images have been washed out for their protection, and their names have been changed as well. We are hoping this podcast will help spur some of you to provide support through Claire’s online site to help provide essentials for the family while they are in hiding, and that it might also help motivate some of you who might live in Canada to help us lobby the government to ensure that their case is resolved as quickly as possible.
Thanks for watching, or listening, and for any help you can provide. Here is a gofundme link to help support them. https://www.gofundme.com/f/please-help-five-afghan-girls-get-to-safety

I began this lecture by saying I was daunted by what I was about to talk about. There are several reasons for this.
First, I will lead you through the development of what was certainly most important theoretical development in the 19th century, and what could easily be considered the most important mathematical framework in all of physics. Second, this development affected our modern picture of the universe more than almost any other. Next, this development made our modern technological society possible. And finally, it allowed a calculation that ultimately unveiled the true nature of light. A calculation we will perform together during this lecture
I am going to take you through what is often taught in a whole semester course in physics. So hold onto your hats. Take it step by step. I think the reward of understanding will be worth the effort. I hope at the end of this lecture you agree with me.
This month I will be traveling with the Origins Project and a group of 27 intrepid travelers to Cyprus and Greece. So the next Origins podcast will not air until August. I hope your July is enjoyable.

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!
We began our discussion describing a new finding of a Giant Ring of galaxies billions of light years across in the sky. The key questions are: Is it real? And is it surprising? We both have slightly different takes on this.
Next we described a new measurement of the strength of gravity on scales from 80 to 800 million light years in distance. And guess what? Gravity falls off just like Newton predicted! This may seem like a big yawn, but one of the most popular models that claims to do away with dark matter would imply that Gravity would fall off differently on these scales. Does this new result kill that idea? Stay tuned.
Microsoft, which has cried wolf a number of times so far when it comes to something called Majorana qubits as the basis of a new viable quantum computer just published a new paper claiming they finally have it. Sabine and I discuss why we are both still skeptical, but why the effort is worth it.
Next, CERN, the large European particle physics laboratory, and the world particle physics community seem to have converged on plans for building a huge new accelerator in the current CERN site.. this time involving an underground ring 91 km in circumference, in which electrons and positrons would collide to explore the detailed properties of the Higgs particle. Is the effort worth it? Again, Sabine and I have slightly different takes on this.
Fusion power, which we have talked about in a number of earlier episodes, continues to tempt humanity with the promise of unlimited energy. Many people, myself included, have tended to argue that fusion seems to be 25 years in the future, and may always be 25 years in the future. But many new efforts are underway, so who knows. Unfortunately, a group of economists has analyzed fusion in the context of other large energy programs and have argued that even if we can achieve it, it may not be as economically viable as many claim.
Finally, one day Richard Feynman went to a Thai restaurant with his young companion Ralph Leighton, and wondered what he should order. Should it be the same old dish he loved or something new. An equation filled napkin later, and he had the answer. Fifty years later some cognitive scientists resurrected Feynman’s napkin and explained it, and argued it might have important implications in other social situations. Such is the power of science.

Alvin Roth is a Nobel Prizewinning Economist whose work on designing markets has had real world impacts that may have saved thousands of lives around the world, while arousing strong emotions both for and against the programs he has helped put in place. Clearly not one to shy away from controversy, he represents the best of what The Origins Project is trying to promote: applying science and reason to public policy. In short, connecting science and culture!
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. As far as kidney transplants are concerned, in the US alone, over 130,000 kidney failures occur each year, and only 20,000-30,000 transplants are performed, because of a lack of suitable kidney donors. Roth has already helped resolve one bottleneck, connecting donors with those in need, through a kidney exchange, which is actually more complicated than it may seem due to medical incompatibilities even within closely related individuals. More generally, not only could lives be saved, but as he shows, it would save considerable money if a rational system of reimbursing prospective donors could be devised.
Beyond his remarkable work tying empirical testing to theoretical ideas, as a human being, Roth is a saint. I have direct knowledge of this. On the day this podcast was recorded, we had an amazing 3 hour dialogue… one of the best I have had. Only problem was, I forgot to press record! We lost it all. With patience and grace that I never expected, Roth agreed to re-record another podcast on the same day. A friend of mine told me was a mensch. But I never expected that. I am eternally grateful, and I hope you will thoroughly enjoy, and have your perspective of the world altered by my conversation with this remarkable gentleman and scholar. Enjoy!

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.
In this episode, we covered an incredibly wide range of science topics. Sabine opened with reported claim that the CIA used quantum magnetometry to find the downed pilot in Iran. The report, in the NY Post, looked fishy. We explain why it is. Then I described a new discovery in the physics of material that may solve perhaps the biggest problem in AI now: heat generation in computers. Sabine talked about a new claimed Big Bang Theory that might have some relevance to quantum gravity. Then I countered with a discussion of yet a new result that suggests the standard model of cosmology may have troubles, or that observers are wrong.
After that, Sabine introduced a paper describing a possible new way to measure gravitational waves. I think it is a fine piece of work, though it is not clear if it is practical. If it were, then the huge interferometers that are now being used could be replaced by ‘tabletop’ detectors. We will see.
Finally, I described an amazingly interesting news story that might have implications for the future of medicine. It also demonstrates what one person, with determination and wealth, can do to possibly cure their own maladies. Sid Sijbrandij, a billionaire tech CEO of Gitlab, was diagnosed with inoperable spine cancer, and launched an amazing program of diagnostics, AI data mining, and a group of scientists who developed vaccines specific to his genetic makeup. After implementing all the procedures, he has been cancer free for a year. While this is beyond the reach of people without these resources now, Sid’s story demonstrates the potential power of combining AI and genetic medicine in the future.
