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.

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!

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.

Quokkas aren't real

Quokkas aren't real
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.

I mean, good for her, but "don't try this at home" should have been the headline.

“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.
"I’ll go down this thread with GPT or Grok and I’ll start to get to the edge of what’s known in quantum physics and then I’m doing the equivalent of vibe coding, except it’s vibe physics,” said Travis Kalanick, the founder of Uber.
