What do you know today that you didn't know yesterday?

I'm a mouthy little bitch.  Well, okay, maybe I did know that, but I at least thought I knew when to shut up.

It's not that I don't know when to shut up, it's just that sometimes I don't want to keep my mouth shut. Especially when being confronted verbally.

So-called free dating web sites are only free for certain large values of free.

If you have a phone that supports apps, just use Tinder.

Saw something today about a new dating app that's having trouble getting off the ground...it's a dating app for Trumpanzees.  Seriously.  Do we need them to possibly meet and breed more than they already have?

No, it is actually the case.

It is typical, for example, to talk about the brightness of a radio emission or an x-ray emission.

Brightess is usually considered to be equivalent to luminosity.

It isn’t. Brightness is (unsurprisingly) how bright an object appears to an observer. Luminosity refers to total EMR emissions.

To speak of the ‘brightness’ of a radio or x-ray emission may be typical, but it isn’t correct.

It is standard usage among physicists. You can even talk about the brightness of an infrared laser.

In these matters, standard usage defined correctness.

From Wikipedia:

Luminous flux differs from power (radiant flux) in that radiant flux includes all electromagnetic waves emitted, while luminous flux is weighted according to a model (a "luminosity function") of the human eye's sensitivity to various wavelengths.

Luminosity and Brightness are both ambiguous terms, and are often used interchangeably.  Neither guarantees that one is doing eye-equivalent weighting, or talking about total power, though brightness is usually used as eye-equivalent (or detector equivalent).

In a series of repeated tests, raccoons were able to open complex locks (‘complex’ meaning a lock requiring four or moves to open) in less than ten attempts 84% of the time. Once they learned to open a particular lock, they were able to do so even after the lock had been rearranged or turned upside down. AND they were able to remember how to do so for up to three years.

The trash pandas are going to take over.

They might be a better option around here.  Obviously, they are smarter than MTG, Boebert, and others of that ilk.
