How quick are your <bra|ket> skills? I turned an old card game into an app: bra-kets.replit.app.

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.

Game idea: reverse of LIFE. Instead of building a family, you spend the whole game trying to get your teenagers to leave the house with enough confidence to fail somewhere else.

You’ve seen me harping about bureaucracy for over a decade. My colleagues have always seen me as a troublemaker for it. But now here we are, paralyzed and poisoning our children. It’s finally boiled over. csferrie.medium.com/for-teens-so...

Apropos of nothing at all, please enjoy this game. Goal: collect tacos, books, and lattes while avoiding guns, red hats, and foxes. codepen.io/csferrie/ful...

PSA: nothing about quantum entanglement is faster than light. Popular quantum physics in a nutshell: Make stupid assumptions, win stupid conclusions.

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! 📘🧪😂

Amazon is nearly giving away books. Go read words on paper!

Lazy parenting hack. Chop up fresh veggies and just leave them out. The kids eat three times as many servings as they avoid during meal time.

You do not want to be one of my open tabs to the right of this one.

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? NOPE! (1/7) 🧪

Blog post: "Actually, you can't test if quantum uses complex numbers" algassert.com/post/2501 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.

I came for the "thank you" chocolates but stayed for the teacher's saying: "I had a chance to meet with a few of the students today and they were still buzzing. "

I'm no AI evangelist, but strawmanning it doesn't add to the conversation.

When discussing screen time with your teen, how do you account for watching multiple simultaneous screens at the same time? Asking for a friend.

Quokkas aren't real

Spend 15 minutes on instrumentalism and save them from 15 years of confusion while blocking false ontological indoctrination.

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.

People are asking where the idea for Quokka came from...

Is this the Florida Man of "in mice"? Something happened in one mouse and he thought the *opposite* might work in humans. I mean, good for her, but "don't try this at home" should have been the headline. www.abc.net.au/news/2025-07...

“Go to the edge of quantum physics with GPT” and start free-associating without doing the math or proposing experiments, you’re not doing physics; you’re generating science-fiction brainstorming. That can be fun, but until someone does the hard yards, it lives in the “vibe sci-fi” bucket.
