It's a definition from a well-respected global standards organization. Can you name a source that would provide a more authoritative definition than the ISO?

There's no universally correct definition for what the ≈ symbol means, and if you write a paper or a proof or whatever, you're welcome to define it to mean whatever you want in that context, but citing a professional standards organization seems like a pretty reliable way to find a commonly-accepted and understood definition.

Sure! See ISO-80000-2

Here's a link: https://cdn.standards.iteh.ai/samples/64973/329519100abd447ea0d49747258d1094/ISO-80000-2-2019.pdf

"Approximately equal" is just a superset of "equal" that also includes values "acceptably close" (using whatever definition you set for acceptable).

Unless you say something like:

a ≈ b ∧ a ≠ b

which implies a is close to b but not exactly equal to b, it's safe to presume that a ≈ b includes the possibility that a = b.

I find it frankly hilarious that all these ships are apparently designed so that damage to just about any part of the ship has a high likelihood of causing a bridge panel, often used by the captain, commanders, and lieutenants, to explode right into the faces of the most important people on the ship.

You would think after reading the 20th captain's log with variations of "Ensign Ricky died after a bridge panel exploded in his face following minor torpedo damage to Shuttle Bay 3," Starfleet might consider some redesigns and retrofittings.

Coolant leak! We've got a coolant leak!

The role of a district court judge is to do two things:

1. Apply existing precedent to individual cases to the greatest extent possible.
2. Set new precedent only when absolutely necessary because the facts of the case don't align well to existing precedent.

Cannon has basically decided to do the exact opposite of these two rules by pretending that the facts of this case are so incredibly unprecedented that she has to throw out the rulebook and set new precedents on everything.

Literally the only unusual thing about this case is that the defendant, a private citizen who currently gets free government security protection for the rest of his life, used to be a president. That's it. Everything else about this case is straightforward obstruction of justice and willful retention of national security information.

"Nah, your fingernails don't need a trim. If she can't handle your adult man's untrimmed fingernails inside her, she does not deserve to have sex with you."

Hair that's long and overgrown can cause problems just like long fingernails can cause problems. Keeping them trimmed so they don't is just being considerate of your partner.

That and the fact that there's a not insignificant number of people who are center-right politically and identify as Republican but don't like Trump or the recent direction of the party. It's not a majority or even a plurality of Republicans, but it's enough to have an impact in close races.

Biden attacking "MAGA Republicans" instead of "Republicans" gives the center-right voters a permission structure to support Democrats because the choice gets reframed from "us (Democrats) vs. you (Republicans)" to "us (the sane ones) vs. them (the crazies)".

The railway strike would've caused shortages of chlorine for city water supplies, shortages of essential medicines like insulin and antibiotics, severe food insecurity and inflation, and would've led to millions of people losing their jobs. Railway freight accounts for 40% of freight transport in the US. Imagine 40% of everything that's made every day suddenly not getting to where it needs to go. There's a reason Congress has never refused to block a railway strike every time it's been threatened over the last 150 years.

The contract was good for the workers but didn't include paid sick days. Congress imposed the contract on the rail workers when a couple of unions didn't ratify it (although most of the unions did).

Biden kept working behind the scenes after signing the law Congress passed to block the strike and got the rail workers their sick days without the suffering a rail strike would've had on the millions of Americans who were already struggling with high inflation on essentials. The IBEW union explicitly thanked him for it: https://www.ibew.org/media-center/Articles/23Daily/2306/230620_IBEWandPaid

While I agree with you, and I do dearly love garlic, I feel obligated to give you a word of caution:

If you eat too much roasted garlic, for the next 24-48 hours, every room you enter will smell like garlic, your sweat will smell like garlic, your farts (and there will be many) will smell like garlic, and your poop will smell like garlic. It will not be a pleasant experience.

Don't ask me how I know this.

30% of Republicans believe violence may be necessary to "save" the country.

They legitimately don't think it's an issue to threaten violence against anyone who impedes Donald Trump. In their deluded minds, he's an innocent victim who only wants what's best for the country and all these evil judges and persecutors and federal employees are trying to take him down and literally destroy the country.

But this guy says another guy told him he knows guys that have worked on the UFOs! That's practically proof of aliens!
