TIL: Just how smart Dirac was. I'm reading a paper of his and the way he's describing things is pretty much a formalism only made rigorous 40 years later because the mathematical framework needed didn't exist at the time (even amongst mathematicians as far as I can tell). The exact method he uses is a bit different and introduces a few extra quirks, but the way of thinking about things is exactly the same.

And then he goes and uses some ridiculous, unclear, non-standard notation and terminology just to throw people off. (I'll ignore the fact the notation and terminology hadn't been standardised then)

I'm still stuck on Cesar Chavez Day
The following is my part of a PM conversation.

It was Mr. Chavez Day; May 31st, His Birthday.
Honey; I don't know what that means to you.
But; ..For some reasons and I don't mind talking about it..
It means a lot to Me.

Buzz Aldrin walked on the Moon;
Where no man had walked before.
What Buzz Aldrin did elevated mankind.

Mr. Cesar Chavez walked on Earth
in the foot prints of many men that had walked before him.
What Ceaser Chavez did elevated mankind.

He Worked in the Fields.
"By age 66 his body was Tired.", is what they say.

When we Honor Mr. Chavez;
In some small way, we honor....
Ourselves, somehow.

Those of us that Worked in The Fields and other people as well.
I will place my part of this PM into the Thread.

Huh, no mention of any region outside the Pacific North-west in the wiki article on totem poles. Are totem poles in Guyana a very recent phenomenon?

Tell you what: this happens in a lot of programs with tabs when it doesn't use the colloquial ctrl+(shift+)tab. Eclipse, for example.

Although TIL that the markdown plugin for eclipse takes ctrl+pgup/pgdown hostage. You can tab into one of its tabs, but you can never leave.

Today I learned that my boyfriend actually doesn't naturally feel like being affectionate and reassuring when I'm scared/upset/distant, but does it anyway to calm me down and reassure me.

My normal reaction when he is being distant is to freeze and wonder what I did wrong and essentially getting more distant...I really hadn't recognised his efforts to keep this thing together until now (I thought it was just natural to him, honestly), and I'm very grateful to him for that (and well, feel bad about my unknowingly leaving most of that to him so far...hopefully can fix that).

I've heard the vegans-don't-eat-yeast-products thing before, but it didn't occur to me until now to note that it is a fungus and that vegans — I think — eat mushrooms all the time, so the don't-eat-yeast thing if true is total hypocrisy.

Just thought I'd add my two cents to the "no yeast for vegans!" conversation:

I am a vegan. I eat mushrooms (although not all that often, really, because I tend to find them a little gross unless they're in little tiny bits) and I eat things that are made out of yeast. I have never (to my knowledge) encountered a vegan who refused to eat yeast-based things, but I have encountered the whole "Hey, if you're a vegan, doesn't that mean you shouldn't eat yeast? Huh? Bet you hadn't thought of that!" attitude quite a few times.

Casual biological misclassification* is a pet peeve of mine, so I'm glad that this doesn't seem to be a common thing.

The one that annoys me the most (because everybody seems to do it ) is describing Phytopthera (a genus of organisms that cause various nasty plant diseases, including potato blight) as a fungus. Yes, it looks and acts a bit like a fungus, but if you look at a cladogram it is literally more accurate to describe humans as a fungus. Phytopthera is an oomycete, which means it's pretty close to being a (brown) alga, and not at all close to being a fungus. Look at the (inferred) last common ancestor - it's impossible to be less related to fungi without being a prokaryote.

Image

Yes, I get that it doesn't really matter, but molecular cladistics is beautiful, and convergent evolution is beautiful, and if you just mush Phytopthera into fungi because that's what they look like (and because that's what they were historically misclassified as) you are making the world a less beautiful place.

Also, notice how small a part of the eukaryote tree animals, plants and fungi are? The rest are known as protists and they are both awesome and under-appreciated.

This should probably have gone in the rant thread...

* and no, I'm not talking about the tomato vegetable/fruit "controversy", because a) everyone knows the biological classification and b) people doing that are clearly using the culinary definitions of vegetable and fruit.
