I’m finding I really don’t like Bluesky (sorry y’all!) - even the chronological order OnlyPosts and Following feeds are trying to incite rage. I suspect it’s because there are still enough people using the algo feeds that folks are still (maybe unknowingly!) incentivized to chase rage likes.

Hey, this is a long shot but maybe someone on here can help. My sister and her wife were accepted to university in Rennes and need to move there before the January term starts, but they’re having trouble finding housing.
Can anyone rent them a room? Even short term is helpful.

I got life-changingly sick right around when I defended. I could not have relocated, and also there were no jobs in organic semiconductors.
I went to a random symposium on campus because I’m a seminar junkie, met someone at an industry poster session, and now I do photonics.

In the aurora, both reds and greens come from fluorescence from oxygen, mostly the from the 1S excited state (green) and from the 1D excited state (red)
The 1D state has a lifetime of >150 seconds, whereas the 1S state has a lifetime of ~1 second

What perfect album came out when you turned 16?
Note: This one’s an amazing straight-through album for a breakup.
Note also: I skipped a grade, so I feel like I should be able to claim Blackwater Park instead - released right around my 15th birthday. My favorite album for the past 20+ years.

as a condition of funding, we were asked to affirm that we wouldn’t undertake any diversity, equity, and inclusion work, whether or not we used the government funds to do so. The PSF simply couldn’t agree to that statement,

"Harnessing Optical Disorder for Bell Inequalities violation"
a joint work with Hugo Defienne's team.

In short : a speckle essentially has a random polarization state at any position, we exploit this to show we can violate a BI.

Color doesn’t exist outside the brain. 🧠
From fruit flies to humans, perception transforms raw light into hues, even nonspectral ones like purple. New work is mapping the neural circuits that make color possible. 🎨
