Vanadium 50 said:For what it's worth, I had determinants years before knowing anything about cross-products.
I would guess that this is unusual. My expectation was that most of my students had seen cross products before in vector calculus or physics classes and I thought it worthwhile to give a linear algebra perspective. I taught them about determinants a couple of weeks prior, so they better had known about them...

That is you who @BillTre wants to write a book for?PeroK said:I just look at the pictures!
BillTre said:What do people use for drawing molecules (in a digital manner)?
I would like to make space filling type models as well as letters representing the atoms connected by lines at different angles.
The second kind I could make with ad drawing program, but there's got to be a better way.

playing "Rogers & Clarke" in the movie "Ishtar"
in the song "Dangerous Business":
Telling the truth can be dangerous business
Honest and popular don't go hand in hand
If you admit that you can play the accordion
no-one will hire you in a rock & roll band
In the mid-'80s I was a not-so-great accordionist ##-## only a little bit better on guitar ##-## my girlfriend could sing very well and was very good on piano ##-## we got a good laugh ##\dots##

As I recall, @Vanadium 50 had posted something about gentlemen not playing trombones, I just followed up with accordions in a similar vein.timmeister37 said:Just out of curiosity, what is funny or witty or interesting about this one ?
BTW, when I lived in New Orleans I saw a guy in the Quarter playing Jimi Hendix's "Voodoo Chile" on an accordion. That's something you don't forget.
