Particle Physicist funded by the @royalsociety, based at @Edinburgh_PPE. If you can't find me in my office I'm probably reading, running, or lifting stuff.

I just gave my first of 3 @CERN Summer Student Lectures on Flavour Physics. Here's the one(ish)-minute recap. Full slides here: https://t.co/NLeJqWsAWD

This but make it hyphen

[Ben Galley @BenGalley]

This morning I have spent 30 minutes deciding on the placement of a comma.

Best job ever.

@WKCosmo Right, but this forces authors to be explicit - no recourse to ignorance should AI misconduct be uncovered downstream

"I was born in a family of refugees, and my parents could barely read or write. My father finished sixth grade and my mother couldn’t read or write. It’s quite a journey. Science allows you to do it. Science is the greatest equalising force in the world."

[Mark Williams @QuarkWilliams]

I gave this talk OTD in Fermilab's Ramsey Auditorium, in a celebratory event.

Happy "End of Tevatron Operations" anniversary to all who celebrate (14 years!)

I did this once! A nice person at the American Airlines desk rebooked me at no cost onto a different flight (from the airport I'd mistakenly arrived at).
Normalise arriving at the wrong airport!

[The Washington Post @washingtonpost]

Heading to catch a flight? Make sure you’re going to the right airport. Seriously.

Customer service managers at Dulles and National said travelers confuse the D.C.-area airports on an almost daily basis. https://t.co/ZZkrpY7inZ

@nationalbook @NewYorker Do you have the list on a site that's not behind a paywall? Thanks!

I'm at the Lepton-Photon conference in Madison, WI, this week. Among a great group of physicists there are three textbook legends: Michael Peskin, Francis Halzen, and Mark Thomson. I should have brought my book copies to get them autographed 📕😎

[Mark Williams @QuarkWilliams]

@forallcurious Just once though

[Mark Williams @QuarkWilliams]

@BristOliver e.g. do they carbonate the birthing pool water?

[Mark Williams @QuarkWilliams]

@BristOliver Out of context, I found myself wondering how home births generate more CO2 than hospital births...

[Mark Williams @QuarkWilliams]

@jamestanton Under a small angle approximation, that you'd dropped 12 metres in altitude

@WKCosmo Is it the nutritionists?

[Mark Williams @QuarkWilliams]

@Samuel_Gregson i.e. it could also help tackle obesity?

[Mark Williams @QuarkWilliams]

The actual story is *much* less exciting than the headline https://t.co/CRIURRZbFJ

Well, this is neat - fully-reconstructed B* -> Bγ decays, and order-of-magnitude improvement on their masses. Chapeau CMS! https://t.co/Foy4twGlpy
