Our latest paper will hopefully be useful to people new to crystal plasticity and explains our code starting from the fundamental equations. Code, examples and paper are open access.

@ericweinstein @SUBWAY Peer review worked extremely well here.
An unknown lecturer submitted one brilliant paper to the Annals. Referees recognised it within weeks, it was accepted, and he got rapid recognition, a MacArthur, and senior appointments. One breakthrough transformed his career.

@Samuel_Gregson Assume for a moment GU were correct (I don’t think it is), how would it actually lead to interstellar travel? The energy required to manipulate spacetime in any useful way is still going to be insane, a deeper theory of geometry doesn’t magically allow a low-energy warp drive!

@KaiserBCFC_ Wow!! 🤯

Here is my view on what’s wrong with funding of scientific research in the UK, and how I would change the focus if it was up to me!

There is a long list of things that UKRI needs to weigh when making decisions about funding for research and facilities, and driving growth is not one of them. The reason is that the whole of UKRI’s portfolio is essential for driving growth - indeed the research ecosystem is one of the necessary foundations of growth. The point I made at the Labour Conference is quite simple. UKRI’s budget is 0.65% of government expenditure, at a little under £10 Bn per year. That is a very tiny leaver when seen through the prism of attempting to use it to make a step change in economic growth - especially when the leaders of UKRI and the Research Councils are not economists and should not be economists! Their expertise lies in research. BUT, and this is the key point - if by fiddling around trying to use this tiny budget (in relative terms) to make a noticeable change in growth you damage the fundamentals, then you run the real risk of damaging the growth potential of the rest of the economy. Universities, research labs, education and inspiration are all essential for growth. This is what UKRI should be focused on because they are the custodians of this VERY valuable but fragile world-leading ecosystem. So, I would say to UKRI, do the thing you are supposed to do, do it well on behalf of the rest of the economy, and do nothing else.

NEW: Oxford has been named the world’s number one University for a record-breaking 11th consecutive year in the @timeshighered World University Rankings.

Oxford has held the top spot since 2017 – the longest run at number one in the rankings’ history.

A 59-year-old conjecture in fusion physics just fell.

Harold Grad (1967): smooth 3D plasma equilibria can't exist unless pressure is constant or there's symmetry.

This week: 3 families of counterexamples. 2 independent papers, posted a day apart. Two found with GPT-6 Astra.

Huge for stellarators.

@AshtonForbes No one has “solved” fusion we are still working on it!

[Ed Tarleton @edtarleton]

I still think about these crisps. They’re never coming back are they? Just be honest with me @marksandspencer so I can have closure.

[M&S @marksandspencer]

@edtarleton We're still on the lookout for the perfect supplier, so please watch this space! Denise

@Rainmaker1973 It doesn’t look exponential it looks like a singularity!

@AnthropicAI Wow! This is incredible. I really am living in the future 🤯

[Ed Tarleton @edtarleton]

@SawyerMerritt @elonmusk Wow! Ever since I saw Total Recall as a kid I’ve been waiting for this!

@Metallurgical_ Careful. BCC has no true close-packed planes, only close-packed directions ⟨111⟩. Its densest planes are {110}, but the atoms sit in a rectangular (not hexagonal) arrangement.
True close-packed planes only exist in FCC {111} and HCP {0001}.

@alma271828 @sonukg4india Very nice! ✅

[Ed Tarleton @edtarleton]

Excited that our latest paper has just been published in PRL! It presents the first thermodynamic model for hydrogen thermomigration in metals and shows that the electron-wind effect can play a crucial role in determining how hydrogen moves.
