I am a professor of physics at Oxford University. I am interested in oxides applications in IT and my techniques of choice are X-ray and neutron scattering.

Students should never have had to pay £9k/y in the first place. The idea that students are customers and should pay for what they get is the legacy of that wretched decision. Students and academics should have fought that much harder, now we are all starting to pay the price.

I completely disagree. A PhD is about education (not training), and a fundamental part of educating a scientist is being able to write papers. Research skills can always be learned later, but framing a problem and constructing a narrative is the hardest thing to learn.

I am particularly happy for John Goodenough, a great scientist and a super-nice guy. The crucial work that is being recognised today was done in Oxford.
Such brilliant news: John Goodenough and his group pioneered the development of lithium cathode materials in Oxford; without this work, the rechargeable lithium battery (and arguably the modern connected world) would not exist.
Congratulations to all three winners.

The other problem with labs (at least at OX) is that it is hard to design summative assessments, so most student do not take them seriously. Good lab courses should be hard and rigorous, with the option of testing theories on synthetic data for the ‘chirality challenged’/end

So a degree in ‘theoretical physics’ is a bit of an oxymoron, you can certainly learn how to become a theorist but you are hardly a physicist if you do not engage with the Hyle. Physics as a broad church should include its extreme mathematical ends, but not for in a UG degree. 2/

One more point to add to this excellent comment. The longstanding doctrine of the MMI to employ artillery to counter asymmetric threats seems to be paying off here. Confidence in the 76/62 means one can commit much later (time to target is much shorter than with ASTER).

Perhaps the best example is that of 3-fold symmetric primitive trigonal space groups, which have 6-fold symmetric hexagonal lattices. This idea dates back to at least the 19th century, so using ‘lattice’ for ‘structure’ was always lazy at best.
