More on ARC job cuts & restructure:
ARC’s spending $374k on consultants for organisational “review” & “planning & development”.
They’re also spending $765k on “risk management”.
That’s $1.1 million on consultants being spent over 1 year.
Un. Believable.
Slow clap, ARC.

My nephew (age 3.5) is coming to visit my lab next week and his top priority is checking whether or not I have all the items in @csferrie.com's "Goodnight Lab." I made sure I know where the multimeter is and I found a spectrometer down the hall so he won't think I'm a fraud! 📘🧪😂

It's easy to forget that #SciComm is for people of ALL ages, not just adults and teenagers.
But is there an age that's too young?

I doom the concept of that 2021 Nature paper by showing how to compile any distributed quantum protocol into real-only gates while preserving locality.

Spend 15 minutes on instrumentalism and save them from 15 years of confusion while blocking false ontological indoctrination.
Should interpretations of quantum mechanics be taught in quantum mechanics courses?
If so, how long should the instructor spend on interpretations-- just a brief mention, or one or more lectures?

New preprint on arXiv 🚀
Link: scirate.com/arxiv/2507.2...
We present a practical step-by-step guideline to determine whether a procedure that claims to circumvent exponential concentration actually works in practice.
See the following 🧵 for more details.
