“For a process that’s anything but exotic, ice nucleation remains surprisingly mysterious. Chemists can’t reliably predict the effect of a given impurity or surface, let alone design one to hinder or promote ice formation. But they’re chipping away at the problem.”

Mathematicians Attempt to Glimpse Past the Big Bang
“Researchers already knew that in a universe with so-called dark energy, but without matter, the start of inflation identified in the BGV theorem is a coordinate singularity that can be eliminated. But the real universe has matter, of course. Might mathematical tricks also make it possible to get around its singularity? The researchers showed that if the amount of matter is negligible compared to the amount of dark energy, then the singularity can be eliminated.”

Hey, neat! Thank you! It's an "imagination engine" - the original mod @Arotrios kbin.social wrote a detailed description here.
I never really fully got my head around it but it seems to be a combination of art, poetry, music, cinema, mythology, etc and a lot of the posts in it bounce off other posts in it.
Seeking Ultimates: An Intuitive Guide to Physics, Second Edition by Peter T. Landsberg, 2020
Takes us on a journey that explores the limits of our scientific knowledge, emphasizing the gaps that are left. The book starts with everyday concepts such as temperature, and proceeds to energy, the Periodic Table, and then to more advanced ideas.
If there are people liking physics here in the #actuallyAutistic ? I was doing my walk and spotted this nice example of refraction of the light with stones on the river bank. The stones look flatter on the right due to the refraction of the light.
What some Lemmy communities that are dead or very low number of new posts that you would like to get more active?
