If you are aware of an interesting new academic paper (that has been published in a peer-reviewed journal or has appeared on the arXiv), a conference talk (at an official professional scientific meeting), an external blog post (by a professional scientist) or a news item (in the mainstream news media), which you think might make an interesting topic for an FQXi blog post, then please contact us at with a link to the original source and a sentence about why you think that the work is worthy of discussion. Please note that we receive many such suggestions and while we endeavour to respond to them, we may not be able to reply to all suggestions.

Please also note that we do not accept unsolicited posts and we cannot review, or open new threads for, unsolicited articles or papers. Requests to review or post such materials will not be answered. If you have your own novel physics theory or model, which you would like to post for further discussion among then FQXi community, then please add them directly to the "Alternative Models of Reality" thread, or to the "Alternative Models of Cosmology" thread. Thank you.

Video Description

Elementary particle physics is one of humanity's greatest achievements. Our description of the fundamental structure of the universe is often described as "beautiful," but the mathematics of differential geometry, representation theory, and quantum field theory needed to see that beauty is inaccessible to most people. Must we resort to using bad analogies? Or is it possible to describe the geometry of particle physics, including the Higgs mechanism, faithfully and accurately but without equations, using only some graphics, an arrow, and some pool floaties... in twelve minutes?

Your ideas using group theory have been a large part of giving me this weird idea that the universe is structured like Pascal’s triangle, with the universe starting off at the top, as a single unitary “everything” and then, though a continuing pattern (as in cellular automata) of simple rules of division and recombination (with the neighbor division), creating an ever expanding universe of complexity and detail and diversity. Pascal’s triangle describes all the possible combinations of fractions of things (a.k.a, all the different symmetries of reality), and if the universe is expanding, then we will continue to see more and more details, which is what we do seem to be doing (the elements, atomic particles, quarks, Higgs particles, etc.).

It’s too simple of a pattern for most folks to believe, but why do we think that the laws of physics need to be complex? Why can’t they be simple, at the very core?

Dear Garrett,

I was very happy to watch again this video, which I enjoyed very much!

If you have time, I would appreciate if you will watch and rate my videos The puzzle of quantum reality and Can a black hole keep a secret?.

Best regads,

Thank you for commenting and rating part 1 of my trilogy of videos "This Is Physics". You asked for feedback on the way you presented the geometry of particle physics to a popular audience in your video, and I am happy to provide some.

There are many strong points to your video: the use of props (the arrow, the inflatable ball and torus), the description of research on the...

Thanks for this review, Marc! I think you're right about the sombrero and Feynman diagrams. I included them as background images for Higgs history because they're so well known to physicists, but you're right that these are too scary to hit people with.

Very happy you liked all those points -- I put a lot of effort into it.

I'll have a look at your other videos.

Well done Garrett!

I think you were indeed successful at showing how symmetry breaking in Physics can be derived from Geometry, without getting complicated or technical. The most innovative use of pool toys I've ever seen! As it turns out; I get to mention your work in my video on the Mandelbrot Set. My research explores the relationship between symmetry and symmetry breaking via that object, and the possible applications to Physics. Of course; a lot of the Physics relevance is because the trends I explore extend into octonionic space, but I have yet to publish that work. Good luck in the contest!

You told me many things I didn't know and very much want to find out more about. I think that your talk was well-delivered, accessible, and inspiring. Thanks for the chance to see it.

I always enjoy hearing you speak, whether it's at a TED Talk or the Science Channel -- thank you so much! Great shirt, by the way.

If you can please vote on our 2 short videos, we would be most grateful:


Have a great day,

Schatzie Dudee and kids

Hi garett

First let me take this opportunity to express my honour of writing to a Physics GREAT like you .Very Wonderful physics from you,ive come across E8 theory on TED talks earlier on,i have worked on m-theory,I agree that all reality commutes to maths and geometry.I love your idea about the science hostel.i adopted it and have wholly worked on the immense theory at home.I publish on too have a simple video -,On the geometry of the fundamental physics of the universe on a notebook .Kindly vote for me i think its in the red,meanwhile i vote for yours.
