Today I learned that Lagrange was Italian and that he lamented the execution of Lavoisier in France during the French Revolution with the quote:

It took them only an instant to cut off this head and a hundred years might not suffice to reproduce it's like.

I see only one apostrophe, and my French is almost as bad as my Klingon, but I would guess that it was not his fault. Wiki seems to have fixed the error:

"Il ne leur a fallu qu’un moment pour faire tomber cette tête, et cent années peut-être ne suffiront pas pour en reproduire une semblable."
("It took them only an instant to cut off this head, and one hundred years might not suffice to reproduce its like.")

ps. Lavoisier named Oxygen.

pps. The wiki entry on his last days: Final days and execution
sounds very much like, um, right now.

ppps. Was that here, FB, or in a dream, where I theorized that the French were nice to us back then, because they knew we'd be here one day?

Never mind. It was on my sister's FB page, regarding her disgust of the images that U.S. kids were tweeting of their icky looking lunches. And then she commented on how healthy French children ate. And then, it happened...OmCheeto: I hope that you are aware, that France has the highest tax burden in the world. hmmm... I wonder if this is why the French, from our very beginning, as a country, sided with us. They went through what we are going through now, 200 years ago. Don't we have a castle in the north of France?

Today I learned how to address a cat:

But always bear in mind that he
Resents familiarityYou bow, and taking off your hat
Ad-dress him in this form: "O' cat!"

(I just now saw the musical "Cats" for the first time, in a TV production on PBS.)

Today I learned a new word, hyperacusis, after Googling for my medical symptoms.

It started suddenly on Tuesday morning. I hope it's temporary, as it's playing havoc with my music-making. In my case, it includes the weird feature that some notes sound at different pitches in my right ear (the broken one) from my left ear.

And now I've learned another new word, diplacusis, which is the medical term for the different pitch effect. (Hyperacusis describes the effect which I've also been experiencing that normal sounds seem frighteningly loud).

As I was reading this thread, I was thinking the same thing. Today I learned that I have to be quicker if I want to make a comment like this.

Today, I learned that there are other people with full brains. :D

ps. The capacity of the average, aka non-PF, brain is a million gigabytes.

pps. I decided, as I said, when I was 18, that I had reached my capacity. So I mentally chose not to remember stupid stuff. I posited this idea to someone about a decade ago. He said it was preposterous. But later, I discovered that he was an idiot, and would probably never fill up his brain, even if he lived to be 1000 +/- 100.

ppps. As proof of my theory, I present Gary Larson's corroborative paper. He was, and still is, a genius.

pppps. Gary Larson lives in Tacoma Washington. Ha! Two things!

Om, you better not leave this world before I do or I swear to the god of popcorn and long lines at the mall that I'm going to come dig up your rotting corpse, reanimate it using a bunsen burner and the static electricity from sliding my feet across the carpet, and then make you continue to post on the forums until the day I die.

I learned it's easier to buy curry paste than gather just the herbs needed to make your own.

Suffices to say I took the easy way.

Today I learned that one of my favorite symbols, the proper time tau symbol, is conspicuously missing from this list, unless it's supposed to be this one,"τ." But that doesn't look like tau, tau has that cool squiggly line on top, like it's a goofy T o0)

I think that's only true if you write your Greek in comic sans.

Today I learned how to thin rubber cement. I have a very old bottle of it that has gotten too thick. I googled and found there is a dedicated product called, straightforwardly, Rubber Cement Thinner!

Be careful with that stuff.

Today I learned that the atrocious Far Cry 4 night-day transition effects (of dusk and dawn) are related to the character's movements. To speed up the process, move around -- even if just back and forth -- rather than standing still and waiting it out.

I also heard that all of the stores would close and that people would spend the day with their family and loved ones.
