Claude Francis Barry’s paintings of WW1 are amongst the most accomplished of his works, with his images of searchlights across London being the most evocative - here (1918) he used small concentrated dots of colour to create an atmospheric haze of light.

One of my father's hospitalizations:
No surgery
Many routine tests
Longer stay due to dementia-fueled confusion and outbursts
5 days

If you can't boycott @maz0n entirely (I couldn't during elder care hell), cut back, ideally A LOT.
If you can't cut back A LOT, then a little.

Hi everyone!! As the holidays approach, it is time for a mass boycott!
Just imagine the impact if people didn’t flood Amazon with holiday orders this year?? If the economy didn’t boom these last two months with billions in sales as it usually does??
Please share this everywhere!!!!

The Cornell AAUP chapter has consistently stated that any deal with the Trump administration would be strategically unwise and a betrayal of Cornell’s principles. This remains the case. At best, we can say that this deal could have been worse.

My book #TransformingNight argues that excessive focus on #LightPollution #ArtificialLight during clear-sky conditions until recently is a legacy of astronomy's early attn to issue.
IOW, even recent scientific assumptions and practices have been shaped by the past.

Insightful paper about distance to cities and cloud composition for the distribution and reflection of light pollution. These kind of measurements should become standard for monitoring, eg, of urban lighting impacts particularly on biodiversity beyond the urban environment.

I'm used to the usual effect of clouds (reflection of light pollution, darkening of the natural sky), but it's interesting to see the zenith being darker than "normal" once the sky overhead cleared but Montreal was still covered, and that the zenith became brighter once the sky cleared over Montreal
