I hold the philosophical position that if two things are indistinguishable, their difference is irrelevant.
"What if we live in a simulation?" -- irrelevant
"What if you couldn't tell the difference between taking to a computer and a real person?" -- irrelevant
But more precisely, it's begging the question to say "imagine something was indistinguishable, now how would you treat it differently???"
A new meta-analysis of "light pollution effect on human health, focusing on the main human pathologies and the types of polluting lights" finds that "the increase in exposure to artificial light triggers mainly sleep and mood disorders, with light from electronic devices and artificial night the main source of pollution."

@kellylepo #JWST continues to amaze. I was aware that the infrared band would enable different views of distant galaxies, etc. but I think I am most amazed by these pics from our own solar system!
Look at these beautiful images of Saturn’s moon #Titan as seen by #JWST!
Titan is a really bizarre world. It’s the only moon in the Solar System with a dense atmosphere. Its surface is covered in rivers, lakes, and seas that are made of hydrocarbons like methane and ethane.
In these infrared views, we can see through the hazy atmosphere to pick out surface features, but also see clouds in the northern hemisphere.
It's getting crowded up there...

The brightness night sky, alive with its own natural light, is often dominated by artificial skyglow. While there are quantitative ways of measuring the brightness of the night sky, subjective estimates of sky quality have their own particular value. Read more about one such approach called the "Bortle Scale".

@atomicpoet it's not the programmers fault. They had no choice. I was one of them.
In the early naughties we tried developing systems that connected on other ports and spoke different protocols.
But our corporate users could not use them. They were on networks locked down by paranoid security engineers.
Only port 80 was allowed. Or port 443.
So we had to rewire it to fit where corporate security firewalls allowed.
And thus, paranoid security engineers forced everyone to make everything look like web traffic. Which of course makes the whole system less secure.

Great stuff from my #TradeUnion.

I cringe with every die-uh-spora that should've been a die-ASP-ora.
@ottaross Memories of my grade 9 English teacher, who used to say “You’re putting the emPHAsis on the wrong sylLABle!”
So, dear #chemistry #chemiverse, I have created a group called @chemistry. If you tag the account in your toot it should auto boost the toot, to see those boosted toots in your timeline, follow the group. Hope that makes sense.
@scottsantens just because something works or is good, people won't necessarily do it.
it's been proven for decades now that schools starting later lets students learn better but hardly anywhere does it
Alberta as a new sovereign. Uh oh.
Here's why the executive coup in Alberta is a threat to democracy and why Danielle Smith is counting on populist Western grievance politics to win her the 2023 election.

@georgetakei Clearly, Santa is a Vorlon 😄
Retired Chem/Physics/Earth Sciences teacher. I'm interested in everything.
I like a good debate that introduces me to other perspectives. I don't waste much time with people who devolve to name-calling or insults, aside to call them out on it.
I think society performs at its best when we take care of others, especially the weakest among us. That means a strong social safety net, with "free" healthcare, education, and public transit. It's a dream, I know.
30+ years of explaining stuff to teenagers has left me with some habits... I'm not a mansplainer, but I *do* like to find ways to 'splain stuff to receptive ears 😊
I like dogs, cats, and astronomy pictures with a bias towards the shorter wavelengths (kinda leaves out all those lovely Hα pics 😄).
The first thing I look at when shopping for cars is headroom/legroom. Saves a lot of time.
