@JohnHolbein1 I read straight away, panic, and then visit again the next day to realise that they are not that bad and in fact I can address them..

I have a rule I never break: When I get an R&R, I don’t read the referee comments for 24 hours. That pause gives me time to fully celebrate the win before diving into the work.

@JohnHolbein1 Or do you ending up squeezing in exercise at the end of stressful days? That was my (n=1) grad school experience.

Look at how exercising close to bedtime can destroy your sleep quality.

Christopher Alexander has an observation about problem solving that I like: you should always be focusing on solving the part that has the fewest degrees of freedom.

The appearance of large language models caused a drastic shift in the vocabulary of academic writing, according to an analysis in @ScienceAdvances of more than 15 million biomedical abstracts published from 2010 to 2024. scim.ag/4780T2E

@pfmanna @JohnHolbein1 Not untrue if you put it that way (I’m a physicist and it’s funny to me how we already have to throw in the towel trying to figure out what three 3 point masses are doing).

@JohnHolbein1 The social sciences are the real hard sciences. Studying beings with free will and emotions is harder than studying atoms and planets and such.

@SocietyQueen999 Men need precise instructions. We need to know exactly, what it is and where it is. Similar to my spouse saying, “Can you get the thing out of the drawer?”. What thing? What drawer? I’m sure it makes sense to her, but I for one will not support such sloppy information delivery 😂

@SocietyQueen999 Here's why. Many decades ago in college, I met a cute girl. She asked to get cigarettes. While digging around, I pulled a small item in a plastic sleeve. Looked like the rain bonnets my mom kept in her purse so I said looks familiar. It was her birth control pills. Ouch.

@kareem_carr Congrats! How was it? Mine was pretty chill, but I’ve also seen defenses that were brutal to watch! (Though I suspect that you totally nailed it!)

@SSadjina @ffaebi Audi übertreibt gerne... ja ABER: Ich z.B. achte beim Autokauf auf folgende Dinge: Buttons am Lenkrad, Buttons für Lautstärke & Klima Der Rest kann von mir aus Touch sein, aber so nen paar Sachen hätte ich gerne physisch :D

2025 Hyundai Ioniq 5 recalled for fast charging fault with loose bus bars. Didn't see any huge headlines about it, so wanted to make sure the news is spread and people are kept safe!

Some of the recruiting letters my husband’s parents withheld from him until he was 24 because “we didn’t want to have travel far to home meets, and you aren’t that smart anyway.” I was there when they handed him these opened letters. He was national champion in high school. He could’ve gone anywhere. Who does that to their kid? He passed advanced physics later on btw. He is incredibly intelligent. I am constantly reforgiving them.

@DarrigoMelanie If that is true, then the cost of ending hunger for one person is around $80. So, how much of YOUR net worth have you used on the cause? Couldn’t you end hunger for several hundreds of people? Have you?

China turns on hypergravity machine to ‘compress’ time and space. China has recently activated what is considered the world's most advanced hypergravity machine, known as the Centrifugal Hypergravity and Interdisciplinary Experiment Facility (CHIEF), located in Hangzhou, Zhejiang province. This facility is designed to generate forces thousands of times greater than Earth's gravity, a capability that scientists believe will enhance their understanding of various natural phenomena, including mountain formation and catastrophic events like dam collapses. The concept of 'compressing' time and space through hypergravity involves accelerating the natural processes that would normally take thousands of years to observe in a relatively short experimental timeframe. This is achieved by subjecting materials or conditions to extreme gravitational forces, allowing scientists to study geological and engineering phenomena in a controlled environment much faster than they would occur naturally. The CHIEF project, which began construction in 2020, is part of China's broader initiative to develop advanced scientific infrastructure, as outlined in its 13th Five-Year Plan. With a significant investment of over 2 billion yuan (approximately US$276.5 million), this facility not only aims to push the boundaries of scientific research but also to address complex engineering challenges across multiple disciplines including deep-sea engineering, seismic geotechnics, and material processing under extreme conditions. The machine's ability to simulate hypergravity conditions far beyond what humans can endure (astronauts experience around 4g during re-entry) provides a unique platform for research into materials science, deep-earth studies, and potentially the extraction of natural gas hydrates from the seabed, which could become a significant future energy resource
