Physics Week in Review: May 28, 2016

Among this week's physics highlights: The complex physics of that viral water bottle trick, Hungarian physicists may have found evidence for a fifth force of nature, and a physicist's thoughts on That Moment in last week's episode of Game of...

CMS: Higgs to mu tau is going away

One interesting anomaly in the LHC run-1 was a hint of Higgs boson decays to a muon and a tau lepton. Such process is forbidden in the Standard Model by the conservation of muon and tau lepton numbers. Neutrino masses violate individual lepton numbers, but their effect is far too small to affect the Higgs decays in practice. Show More Summary

Of Spies and Spacetime

Stephanie DeMarco interviewed me a few weeks ago for an article she was writing about the science in the TV show Agent Carter (season two). As you know, I did a lot of work for them on the science, some of which I've mentioned here, and we spoke about some of that and a lot of interesting other things besides. Show More Summary

Low-mass particles that make high-mass stars go boom

Simulations are key to showing how neutrinos help stars go supernova. When some stars much more massive than the sun reach the end of their lives, they explode in a supernova, fusing lighter atoms into heavier ones and dispersing the products across space—some of which became part of our bodies.

Gestures

I'm trying to make the characters somewhat expressive, since you, the book's reader, will be spending a lot of time with them. This means constructing lots of hands doing things. Lots of hands. Hands take time, but are actually rather fun to construct from scratch. Show More Summary

Holographic operator ordering?

3 days agoAcademics / Physics : atdotde

Believe it or not, at the end of this week I will speak at a workshop on algebraic and constructive quantum field theory. And (I don't know which of these two facts is more surprising) I will advocate holography.More specifically, IShow More Summary

Killler Asteroids

During my recent vacation I visited my old friend Nathan Myhrvold, and got a tour of his company’s lab near Bellevue. At that time he told me about what he had been working on recently, which has now appeared on … Continue reading ?

Of bison and bosons

What are all of the symbols in Fermilab’s unofficial seal? When talking about Fermilab’s distinct visual and artistic aesthetic, it’s impossible not to mention Angela Gonzales. The artist – Fermilab’s 11th employee – joined the lab in 1967 and immediately began connecting the lab’s cutting-edge science with an artistic flair to match. Show More Summary

A New Era

Many years ago, even before the ground was broken on phase one of the Expo line and arguments were continuing about whether it would ever happen, I started saying that I was looking forward to the days when I could put my pen down, step...Show More Summary

Beyoncé and LIGO: Stochastic Awareness of Science Is Probably Okay

I’ve had this piece by Rick Borchelt on “science literacy” and this one by Paige Brown Jarreau on “echo chambers” open in tabs for… months. I keep them around because I have thoughts on the general subject, but I keep not writing them up because I suspect that what I want to say won’t be…

Physics Blogging Round-Up: Books, Entanglement, Optics, Many-Worlds, Two Cultures, and Clocks

A whole bunch of physics posts over at Forbes so far this month: —Recent Physics Books: Gravitational Waves and Brief Lessons: Short reviews of Janna Levin’s Black Hole Blues and Carlo Rovelli’s Seven Brief Lessons on Physics. —The Real Reasons Quantum Entanglement Doesn’t Allow Faster-Than-Light Communication: Expanding on and correcting some stuff I didn’t like…

Physics Week in Review: May 21, 2016

Among this week's physics highlights: what daffodils can tell us about vortex shedding, new evidence for the pilot wave alternative in quantum theory, and the physics of Ant Man's transformation in Captain America: Civil War. Me at Gizmodo: How Daffodils...

Gut Feeling…

Still slowly getting back up to speed (literally) on page production. I've made some major tweaks in my desktop workflow (I mostly move back and forth between Photoshop and Illustrator at this stage), and finally have started keeping...Show More Summary

My Quora session

Here it is.  Enjoy!  (But sorry, no new questions right now.)

The Planck scale

The Planck scale sets the universe’s minimum limit, beyond which the laws of physics break. In the late 1890s, physicist Max Planck proposed a set of units to simplify the expression of physics laws. Using just five constants in nature...Show More Summary

Division of Labor Is a Good Thing for Science and Skepticism

Noted grouchy person John Horgan has found a new way to get people mad at him on the Internet, via a speech-turned-blog-post taking organized Skeptic groups to task for mostly going after “soft targets”. This has generated lots of angry blog posts in response, and a far greater number of people sighing heavily and saying…

Back

Now back after a satisfying vacation amidst very large trees. Here are some things of note from the past couple weeks: For those fascinated by the arguments over string theory, you might want to look at a document sent to … Continue reading ?

Excited!

Actually, I’m super-excited…! There is a New Hope coming. I’m daring to dream… ok just a little bit. (Sorry to be cryptic…More later.) -cvj The post Excited! appeared first on Asymptotia.

Why do objects feel solid?

The way you think about atoms may not be quite right. A reader asks: "If atoms are mostly empty space, then why does anything feel solid?" James Beacham, a post-doctoral researcher with the ATLAS Experiment group of The Ohio State University,...Show More Summary

Imaginary Syllabus: Science of Sports and Games

It’s one of those days where none of the stuff I probably ought to be writing seems even slightly appealing, so instead I’m going to do something frivolous and morale-boosting, namely think out loud about an imaginary course. Despite being on sabbatical, I do still check my work email, and have caught the edges of…
