Perfect weather for the Upper Harbour regatta

Perfect weather for the Upper Harbour regatta
I have finally been driven to write this; please enjoy my rant about the "power" of entanglement in quantum computing. The short version is it's not a superpower, it's a computational *relief*. haymanphysics.com/blog/2025/badcounting

Please Stop Counting Badly
I need the world to stop saying entanglement adds "power" to quantum computing. Please. Please stop.

Particle physicists ⚛️, what do you think, is it about time we gave the Interaction picture a more catchy name?
My pick is the "Schrödinberg picture", but I will also accept the "Heisinger picture".

I like to call this a little random act of #scicomm:
Instead of cluttering up the root level of my new website, I put my publications in a blog post. But to justify putting them there, I also wrote a lay summary of each paper so there's something for everyone.

Don't you just love that feeling when you're writing something and you figure out that *perfect* little connection you were looking for?
In other news, I think my next piece on time is going to be pretty nice.

Just completely rebuilt my website and realized I never shared my article about time as a thing in physics. If you've ever found the language around time confusing, here's a little primer (and on a shiny new canvas). haymanphysics.com/blog/2025/ti... 🧪 ⚛️ #scicomm

Paraphrasing: Today's top quantum computers have shown they're really good at simulating themselves and... that's about it.

Is it just me, or is the phrase "potential for breakthroughs" completely meaningless? I mean... going for a walk has the potential for a breakthrough...

Crimea is Ukraine.
Donetsk is Ukraine.
Luhansk is Ukraine.
That’s a fact.
Russia’s “referenda” in these territories were shams, held at gunpoint. That’s also a fact.
Facts matter.

How is this just... the best headline ever?
Finland turns down US request for eggs
"The amount we could export would not solve their egg shortage," says the head of the Finnish Poultry Association.

It's not nuanced. It's not complicated. It's old-world conquest and equivocation is a vote for the aggressor.
Russia has kidnapped tens of thousands of Ukrainian children. Putin was indicted for this crime. Yale has a unit searching for them. Musk eliminated the funding.

I have the strangest relationship with #invincible.
I *love* this show, it's phenomenal. S3 staying strong.
But I completely forget it between seasons. I can't even explain why it's so good, it just... is.

See the middle of this blob of gelatin? It's clearly very stressed, but it's not so clear what that means in terms of simple forces and shapes. If the blob were a quantum thing, we would say it was in an #entangled state. Read more about that here: haymanphysics.com/blog/2025/qm3
