On Christmas Eve 1968, in Lunar orbit, the Apollo 8 crew took this photo: “Earthrise."
I'll never forget how inspiring the Apollo missions were to my brother and me as kids. They showed us what our country and humanity can accomplish when we work together toward a common goal.

Increase in productivity since 1979: 87%
Increase in hourly pay since 1979: 32%
Just so happens that ~25% of workers were unionized in 1979. Today? 10%.
As unions declined, the super-rich have taken a larger share of wealth generated by labor. We must build back union power.

This iconic Fabian Todorovic cartoon is still one of the best I’ve seen at illustrating the remarkable amount of space we surrender to cars, leaving little space left for everyone and everything else. The text added later makes the bonus point that many drivers still manage to complain about it.

Topo Trail Run. East Fork State Park, Ohio. Still running shorter races while trying to build back after 18 months of injuries. Not to mention old age and some lazy training. But, still enjoying it.

After being told by a female relative that I have TDS it was hard not to respond, “quiet piggy.” But, I couldn’t go there.

I was diagnosed with #HIV in 1998, when I was 30.
Many of my friends had died of AIDS. I did not expect to live to 50.
I’m 58 now.
HIV treatment works.
Treatment also makes it impossible for me to pass HIV on during sex.
Ensure HIV treatment for all.
End HIV stigma.

"Academic accommodations for anxiety convey two harmful messages. First, they imply that the feared situation is truly dangerous. Public speaking, testing, or lunch with classmates are too risky...Second, they suggest that the student can’t withstand the distress. Those messages increase anxiety."
Schools Are Accommodating Student Anxiety — and Making It Worse
Removing stressors robs students of growth opportunities, writes TC's Ben Lovett and his co-author Alex Jordan

#chemchat #chemsky I need your recommendation for a very high boiling point solvent that can be used at 300C. Ph2O is not high enough (it goes to around 250C). Cannot be protic, cannot have amines. It doesn't need to be a liquid at room temp. Ideas?

Is IR spectroscopy dead? Is anyone routinely using it? Can it be used to indicate purity? I figure I’m just clueless here - my company goes with other methods (e.g., NMR, HPLC-GC, KF, MP/BP, titration, ion chromatography) to access structure/purity. #chemsky #chemchat
