You will never understand how quantum computers work

Correction: racing to results was always pointless. If AI prevents academic fiefdoms, I, for one, welcome our robot overlords.

Colloquium by @csferrie.com (author of the Baby University books) at @leidenscience.bsky.social on 'What you shouldn't know about quantum physics' Of course on a day that I'm not in Leiden 🥹. Bad news for me, good news for you since you can just register www.universiteitleiden.nl/en/events/20...

A government struggling with problems at home discovers the political value of having a foreign enemy, settles on Canada, turns trade grievances and border tensions into patriotic outrage, watches the media amplify every provocation, and then discovers that a fake crisis can become very real.

People out here making fun of teenage boys for their high taper fades not knowing how old-school cool it is. Here's a student with Robert Millikan circa 1930, building electroscopes to detect cosmic rays, who looks like he jumped out of a 2026 barbershop window ad.

I used to pay $600 and now enjoy a "100% savings." How much am I paying? In the new math, here's how you figure it out. $600/$600 = 1×100% rise. So if the price is $600 and drops to $600, that's a 100% savings.

When Einstein developed general relativity the closest thing to a practical application that could even be imagined at the time was a slightly more precise description of where to look for the planet Mercury in the sky, and yet now we’d all be literally lost without it. Anyway: fund basic research.

McDoing is a great term to describe the modern trivialization of existentialism as consumable performance. Anguish is content, commitment is a vibe.

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! 📘🧪😂
