A message from Lawrence:
On June 4th, The Origins Project Foundation and AUK co-sponsored an event entitled Changing Minds in Changing Times. Locally co-ordinated and hosted by John Richards, the event included numerous lectures, by me, Sophie Scott, Blay Whitby, and Keith Porteous Wood as well as an award ceremony for Richard Dawkins followed by a dialogue between the two of us, and an auction for a painting of Christopher Hitchens. AUK is releasing videos of various parts of the event over the course of the next month, and The Origins Project Foundation will release videos of my lecture, and my dialogue with Richard our KZbin channel as well. Critical Mass paid subscribers will have access to both of these videos in advance, ad-free.
Attached here is a link to the video of the first live in person lecture I gave on my new book, The Known Unknowns. It was brief, given the constraints of time at the meeting, so it only covered a few topics, but it was fun to be able to discuss them in front of a live audience. I hope you enjoy it.

The Origins Podcast, a production of The Origins Project Foundation, features in-depth conversations with some of the most interesting people in the world about the issues that impact all of us in the 21st century. Host, theoretical physicist, lecturer, and author, Lawrence M. Krauss, will be joined by guests from a wide range of fields, including science, the arts, and journalism. The topics discussed on The Origins Podcast reflect the full range of the human experience - exploring science and culture in a way that seeks to entertain, educate, and inspire.

You're senseless like Krauss. He never explained a universe from nothing, he just changed the definition of nothing to suit him. Then from there it got worse for him.

One of my favourite demonstrations to explain how a constant speed of light can cause two observers to see things in a different order, that is really easy to understand is this: You get two people to stand an equal distance from you, but have them stood so they are 90 degrees apart if you are at the centre of a circle. You represent the centre of the galaxy, you hold two balls representing stars. You then hold your arms out pointing at each person, then drop the two balls at the same time representing them going Supernova. You then ask them, from their perspective which ball would have gone supernova first. Obviously, it would be the one you were holding out towards them. Despite both going supernova at the same time, over such great distances, the speed of light makes time very subjective.

I began my physics studies at UCLA in 1964 with "texts' being Feynman's Lectures in Physics delivered when he was at CalTech. Within 3 yrs, I was simulating the ammonia molecule's Schrodinger's Equations, Fortran programming it's computations. I was working on terminals next to early speech synthesizing and biomechanial models. Upstairs they were testing the first nuclear magnetic resonators used in today's MRI. Most of what's changed since then is that Americans get MBA and medical degrees, not in the physical sciences or even economics anymore. We live off our past achievements and foreign students in our grad programs.

Rumsfeld was summarizing a theory known as 'The Johari Window,. It is a framework for understanding conscious and unconscious bias that can help increase self-awareness and understanding of others. It was created by psychologists Joseph Luft and Harrington Ingham in 1955. The model is named by combining their first names. It consists of four ' window panes' 1. Things we all know 2. Things we know and no one else knows 3. Things we know we don't know 4. Things no one knows.

Quite dishonest and unintelligent imo. The majority of science in the US serves military purposes and is antipathetic to the often repeated myth that there is a scientific community centred on notions of questioning, openness, transparency, and sharing.

"If you wish to make an apple pie from scratch, you must first invent the Universe.” "If your goal was to create human life, you must first invent the Universe.” These statements are equivalent; this talk accepts the first but rejects the second. You can’t prove the Universe was made for humans, or life in general. But if that WERE, in fact, the intended goal, then you would need the entire Universe (or Multiverse, if such a thing exists) to accomplish this goal. Fine-tuning cannot be demonstrated (we don’t have enough information to develop Bayesian priors for such a question), but you cannot simply rule it out because we’ve discovered all these other variables.
