Glad I didn’t spend the last ten years on that problem! As my CERN advisor suggested :)

All Alumni know that the best discoveries happen after hours of reflection on R1 tables during Summertime. :)

Hmm... The Reality changed itself when guys in Siberia changed the sensor? Some years ago I was playing with the idea that the Reality might invent new laws when people look for them, and doesn't bother with laws when no one observes them. It would be in the style of Copenhagen interpretation, though even with regard to it, the idea seems too weird to be true. But now we have an experimental evidence.

In any case it gives me ideas how to check the hypothesis. If the Reality has a limited horizon for planning for new laws, scientists can trick it into inventing new laws that eventually (after some more research and even more laws observed) would start contradicting to each other, and at that point the Reality would snap into a different set of rules.

If it is true, then the plan is like this: we need to wipe all the scientific knowledge from this world and start again, and trick the the Reality into devising better laws of nature. Ah, wait, we have no evidence that the Reality can abandon laws that were introduced already. Pity, the plan is brilliant, but how to check if the Reality can abandon its laws? If laws are local... we can do something like Stephenson described in his Anathem: establish maths doing independent research and comparing their results once in 1000 years.

You might want to read Dan Simmons' Ilium and if you can stomach some weird post-9/11 shit, Olympos. One of the overarching themes is what you describe... or similar.

I love how the closer we get to “the edge of the Reality”, the more it sounds like the ramblings of someone that got their hands on some of that GOOD stuff

There are several books from Greg Egan with this idea in mind: Permutation City and Distress. The latter one is exactly about this idea.

It's good for the world but terrible for the practitioners in academia. Imagine you are in your last year of your PhD and then something new comes out and completely invalidates/obsoletes your results. Cough natural language processing PhDs during COVID when GPT-3 came around..

Academic here. It's actually great for us. You're usually the first to see the implications for your niche area and have a chance to get a hot paper out rather than a moderately impactful one.

This happens in biology all the time.

PHDs will spend years mastering some intricate multi-day long procedure to do some thing and a new discovery will obviate the need for the procedure completely.

Einstein wanted to measure how fast Earth moves through ether as his research thesis.

I remember reading the Three Body Problem, and thinking to myself: this is implausible. If scientists started getting weird results, they'd be thrilled, not suicidal!

I believe the alien scientists were depressed by the guaranteed collapse of their civilization, not the difficulty of certain differential equations. So it's more like a doctor getting weird results while working on a cure for a pandemic.

Edit: oops, see the reply below... and my grumpy response. I seriously forgot about that entire plot point.

Specially because only particle physics suddenly became inconsistent. I can see scientists fruitlessly obsessing with finding why the universe was toying with them, but suicide? OK, they were also seeing intent with individualized hallucinations, and computer interference, but IIRC those messages asked them to to stop particle physics, not to off themselves. They could change fields and live on.

They were getting inconsistent results, not just weird ones. However I agree that suicide probably wouldn't be where they would end up.

In the book they get different results on all tests they run, consistency is gone, that is something else.

well maybe depends how fundamental

if objects you put on a table started falling through the floor it would be a bit stressful

lol

but Dr. Becky gets really excited about all the various "crisis in cosmology" because she knows new science/knowledge will emerge from solving those questions

and you remind me there's another season coming up in that series, can't wait

I am a bit sick of this narrative. That science can make mistakes is in no shape or form, one of its strengths. It is a weakness of the process.

The lipstick putting can be exposed by simply asking if you would not prefer a version of the scientific method that is never wrong.

Mathematicians proof theorems so they are always correct. Physicists don't have that privilege.

I really dislike the writing style of being so "friendly" for people who don't know anything about the space that you obscure what the topic of the article is at all.

It's a third of the way through the article when "g-2", the problem at hand, is mentioned. Information that should have been shared in the title took a third of the article to figure out.

You dislike that people write for audiences other than yourself.

I dont particularly agree with this article, but there have been quanta articles i've read in the past that went so far trying to make the topic accessible that it became incomprehensible. Where they used so many metaphors and simplifications that it lost all meaning.

Science writing for a general audience is really challenging.

Dylan16807 32 minutes ago

Writing for an unfamiliar audience doesn't mean you should hide the name of the problem until after a huge pile of setup.

No.

If you're writing an article about a man going to the store to buy a sandwich, the man, the store, and the sandwich should all make appearances by the end of the first paragraph.

These people are writing informative articles like novels and it's incredibly irritating and a disservice if you're actually trying to inform anybody about anything. If you're writing an article about the g-2 anomaly, "g-2 anomaly" belongs in the title not 1/3 the way in.

pmontra an hour ago

Yeah, Quanta articles are way too long. They could get to the point in one quarter of the length.

gloryjulio 3 hours ago

Yep. This would backfire spectacularly for people just want to know what's going on. They would just dump the article in the llm and ask, 'what problem is this article about'
