ISO8601 / RFC3339 gang represent. You’ll have to take four digit years from my cold, dead hands.

Pretty sure I fought one of those in Silksong.

Maybe it’s like Toy Story. Batman figure just found out he’s a toy, drank a bunch of Jäger, and then reverted to the dormant state because someone was looking.

That was when they replaced all the birds with bird-shaped drones. People think it was for surveillance, but it was actually to contain the Bermuda Triangle threat.

- Comment on What would happen to the Earth if it got booped by a giant asteroid going super slowly? 2 months ago:
Imagine a large rock, suspended by helicopters a few miles up in the air.
Now drop the rock. How fast is it going when it hits the ground?
The same thing is true for a rock falling from space, but more so. Regardless of initial conditions: if it ever contacts the ground, it will be moving at least 11 kilometers per second.

Weak. You want to stop a train quickly, just suplex it.

To be clear, this glassware isn’t for the lab worker, it’s for chiral molecules that are left-handed or right-handed. As explained by famous chemist Walter White. /s
- Comment on CATL announces sodium batteries that cost as little as $10/kWh, a massive price reduction compared to the current average of $115/kWh for lithium-ion batteries. 4 months ago:
Where are they getting batteries for $115/kWh? Going market rate for LiFePO3 seems to be at least 10 times that.

Yes, they were organic dyes. At the time, those were the only kind. Maybe it’s gotten better over the years.

This is terrible advice. Writable DVDs degrade quickly, even if they’re stored away from sunlight and heat. Every single one of my burned DVDs from more than s few years back is completely unreadable.
- Comment on My foot found the worst Lego that can be stepped on. 4 months ago:
In this case, I knew it because of a “botanicals” set that I assembled recently.
Those sets use a lot of pieces in creative ways, often in unusual colors. In particularly obscure cases, like this crown or the rose petals that were originally from a car fender, the manual will include a brief trivia callout.
I remembered the callout, and that was enough to find it by keyword on the fan database sites.

Ah yes, the 39262 minifigure crown, also used as a flower.

Strictly speaking, you are correct. The key assumption for my statement above is that both objects are black-body radiators.
In practical terms, it still ain’t happening when the light source is a bunch of fireflies.
Aside: Lasers are a really weird case. The population inversion required for stimulated emission is basically the opposite of a classic thermal equilibrium. By some definitions, they are so hot their “temperature” wraps around to negative (i.e., less than zero Kelvin). That factoid took me a while to wrap my head around.
- Comment on strobe party 8 months ago:
Unfortunately, this idea isn’t going to work.
Lenses and mirrors can’t focus a diffuse source to a sharp point. They are also reciprocal; any light that can move one way through an optical system can also move the other way. As a result, you can’t use a lens or mirror to heat something beyond the temperature of the light source. The meet for of energy is always from the hot thing to the cold thing.
For the sun, that limit is almost 6000K, so you can do some damage. For fireflies, not so much.

It would be obvious the moment he opens his mouth. That stupid word salad is instantly recognizable.
