@suzanna1066 @IanCopeland5 @naomirwolf I was an english/film major myself and glad to understand the clarification. Sooo when we see the full moon from Earth the far side is dark. When we see the new moon, the far side is not dark? Is that correct?

@LibZionistNerd @d_h_sanders Sorry man that is politics as long as one side is determined to instal horrible policies. If they get back to just debating tax rates etc the stakes go down.
Welcome to adulthood it's not fun.
English
@d_h_sanders People would not like every single election to be some potentially existential crisis that dooms everything we love to complete oblivion.
English
I’m still trying to figure out why for the past 10 years the worst person in the world continually ran for president and many people decided the only alternative they would accept was someone who would fix politics forever in a single election

@DEF_NOT_DEAF @wisplite @inkysputter @mathsboi42 Got to spread out the cameos one during the lead up episode, one during the landing, and one during the "catastrophe" episode that gets easily solved.
Of course Collins gets whichever episode is expected to suck.

@blurrybonez @GhostedAisle @sharazer07 @brandnewandy @cagowago @PeterROCK_ @_glorianas I'd say 2,400 years does qualify as thousands of years.
It's been known for that long and hypothesized for a few centuries prior.
English
@GhostedAisle @sharazer07 @AEngineerReacts @brandnewandy @cagowago @PeterROCK_ @_glorianas Thousands of years is simply false and a stretch.

@sharazer07 @brandnewandy @cagowago @PeterROCK_ @_glorianas What about civilians who go to Antarctica, have personal friends who've been there and aren't part of any conspiracy.

@brandnewandy @cagowago @PeterROCK_ @_glorianas Why don’t you look in to the Antarctic treaty & what military workers who worked in Antarctica say about sky ice ?

@PennyCrayon5 @mathsrick_ Good instincts, you are correct.
English
@mathsrick_ Without cheating/looking/calculating , I'd say it can't possibly be A, because 2 squared plus 2 squared is 2 cubed
And it can't possibly be B
And D feels like it'll be too low
So I'd say C because it feels about right

it’s so crazy how literally everyone ever except for 4 people is in this photo

We see our home planet as a whole, lit up in spectacular blues and browns. A green aurora even lights up the atmosphere. That's us, together, watching as our astronauts make their journey to the Moon.

@SuperRocy See you didn't get the joke. No one is acting like Bush was sensible, he was an idiot led by Chaney to do horrible things. Even with him being that bad, Trump is worse.
That's what is being said here.
English
@AEngineerReacts The jokes sucks and so does he.
If the butt of the joke revolves anywhere around trying to act like Bush was more sensible, it's a terrible one already.
English
Holy fucking shit man.....This is what we're doing now??? Democrats GLAZING FUCKING BUSH??? REALLY???
Completely talk about actual bad instincts.
Good fucking god Newsom is so fucking stupid and Liberals REALLY trying to push us to have this moron as our candidate???

Smartest Republican President of the new millennium

Now that Artemis II has launched we have 10 days to get everyone on Earth a Planet of the Apes costume so we can do something hilarious when the astronauts return 😁

@KartikGadaATOM @OurWorldInData There are limits but many companies are working on ways to continue the downward trend and we haven't hit the bottom (or got close) yet.

@OurWorldInData The question is, will this trend continue? It is a 'Moore's Law' for batteries.
Another 50-75% reduction in price would be transformative to the world economy.
English
✍️ New article: Battery costs have declined by 99% in the last three decades, making electrified transport a reality—
Over 20 million electric cars were sold globally in 2025 — some for as little as $10,000. Even just two decades ago, that would have been impossible.
The reason it's possible now? Batteries have gotten *much* cheaper.
In 1991, lithium-ion battery cells cost around $9,200 per kilowatt-hour. By 2024, that had fallen to just $78 — a decline of more than 99%. You can see this in the chart.
To put that in perspective: the battery cells in a standard electric car today cost around $5,000. In 1991, those same cells would have cost nearly $600,000.
There was no single breakthrough behind this. Batteries follow a “learning curve”: as cumulative production grows, thousands of small improvements in chemistry, manufacturing, and supply chains drive prices down.
Since 1998, every time global cumulative battery production doubled, the price dropped by roughly 19%.
Early progress was driven by consumer electronics — phones and laptops — before the technology became viable for cars, buses, and larger energy storage.
Energy density has also more than tripled since the 1990s, meaning batteries can now store far more energy for their volume.
The half-a-million-dollar battery was never going to transform transport. The $5,000 battery is.

@BenjaminOCall The solution to affordable cars isn't building new cars for rich people, it's building and selling used cars.

the solution to the housing crisis isn’t building luxury flats it’s building affordable homes

@JessePeltan Nights are easy to solve for. A cloudy day, doable with over capacity.
But cloudy *months* when few daylight hours isn't feasible with solar and storage alone.
English
Believe it or not, Elon has actually known that the Sun doesn’t shine at night since at least 2016, possibly even earlier.
SharpFox@SharpFoxHQ
@elonmusk @JessePeltan Enough surface area, sure. But the grid isn’t ready. Solar works when the sun’s out. Nights and cloudy days? Still need something else.
English
@ItsSteveBee @JessePeltan If only we had another source of cheap electricity that operated best at the opposite times of year that solar operates best.
English
Overnight, yes, sure. A cloudy day, probably still doable, but entire months like Dec, Jan. in New England, when panels remain snow-covered, is tough. Residential panels are easy to clean with a roof rake perhaps, but I've never seen people do snow removal on a 200 acre solar farm like Farmington, ME's Most of the world will be fine with solar and some batteries, but places like New England in the winter will have to import massive amounts of power for weeks on end.

@thetechgooner @H0H0v Is it a bad or good sign I came up with -6 first?
English
@H0H0v 5 or -6.
a + a² = 30
a² + a - 30 = 0
Factors of -30;
1, 30
2, 15
3, 10
5, 6
Only factor with diff of +1 is -5 & +6;
a² - 5a + 6a - 30 = 0
a(a -5) + 6(a - 5) = 0
(a - 5)(a + 6) = 0
a = 5 or a = -6
5 + 5²
= 5 + 25 = 30.
-6 + (-6²)
= -6 + 36 = 30.

@Atom_Person @junpeiliker Was hoping I would not have to scroll too far to see this and was not disappointed.

WHO is saying doggy dog world
Merriam-Webster@MerriamWebster
Not to be THAT dictionary, but… It’s ‘per se,’ not ‘per say.’ It’s ‘dog-eat-dog world,’ not ‘doggy-dog world.’ It’s ‘hunger pangs,’ not ‘hunger pains.’ It’s ‘one and the same,’ not ‘one in the same.’ It's 'buck naked,' not 'butt naked.'
