Before the charm quark was discovered in bound states, it was predicted via indirect effects. An early success story of the electroweak model and QFT!

Mary Gaillard and John Rosner, who both passed last week, contributed to calculating the charm quark mass

In operating theatres at UCLH this morning, with our wonderful theatre teams. Many people from many places, all of them helping us deliver the care. Couldn’t do it without them.

The problem with most machine-based random number generators is that they’re not TRULY random, so if you need genuine randomness it is sometimes necessary to link your code to an external random process like a physical noise source or the current rate of US tariffs on a given country.

An unexpected surprise. The 2025 Breakthrough Prize in Fundamental Physics honors over 13,000 researchers whose labors have led to the precise description the Higgs mechanism, … breakthroughprize.org/News/91 @CERN

🔥 This is an absolutely devastating set of figures on the UK public's view of Brexit.

Absolutely damning. Look at each category one by one - particularly the economic ones. YouGov article on these data here. 👉 yougov.co.uk/politics/art...

This is what the government did with 120K+ Japanese Americans in 1942.

I know. I was there in those camps.

Celebrating the Standard Model: The Magic Angle How did particle physicists become so confident in their Standard Model's equations? Here's the story of the Z boson and its magic angle.

⚛️🧪Over the past years I've been writing a series of posts about the amazing Standard Model of particle physics. I've recently written about its special angle and its role in convincing physicists that they were on the right track. First article is this one profmattstrassler.com/2024/11/20/c...

'Fireside' Al Maitland reads Frederick Forsyth's The Shepherd | CBC Radio The year is 1957. An RAF pilot is heading home from Germany for Christmas. Fog sets in, and all radio communication is lost.

Required listening (one night late, oops): "Fireside" Al Maitland reads Frederick Forsyth's "The Shepherd"; a CBC tradition. "The year is 1957. An RAF pilot is heading home from Germany for Christmas. Fog sets in and all radio communication is lost."

Before 'one small step': How Apollo 8 became our first true moon shot The historic flight launched 50 years ago this week.

Apollo 8 -- the first mission to see humans leave Earth and orbit another world (and capture the famous "Earthrise" photo) -- was launched 56 years ago today. A while back I wrote about the significance of this historic achievement, for @nbcnews.com: #Apollo8 #NASA www.nbcnews.com/mach/science...

Photo of a dark-blue-and-white poster with lots of text tacked to a white wall. The poster title reads "HOW TO MAKE YOUR RESEARCH GROUP MORE INCLUSIVE FOR AUTISTIC TRAINEES", and its five sections are titled "Dispel your misconceptions", "Communicate clearly", "Check the sensory environment", "Be aware of different cognitive profiles", and "Model inclusivity to your group". At the bottom is a QR code leading to the link in the main post, where the full text of the poster can also be found.

ATLAS releases precise new measurement of Higgs boson production in association with top quarks As the heaviest elementary particle in the Standard Model, the top quark is pivotal for understanding the origin of mass. The ATLAS Collaboration is studying the production of the Higgs boson together...

Post-Brexit Britain’s Trump problem goes much deeper than trade tariffs. Latest post on my Brexit & Beyond Blog. The discussion of how the UK might respond to Trump's tariffs is already confused, and anyway misses the bigger challenge they betoken: chrisgreybrexitblog.blogspot.com/2024/11/post...

‘Phonetic’ is not.
‘Abbreviation’ is 12 letters.
‘Thesaurus’ doesn’t have a synonym.

Say what you will about English, but it has a sense of humor.

Snow is falling in London (son sent us a video!) so thought you might like a reminder that here in Scotland we name the gritting machines and there’s a site that tracks where they all are!
