squamous cuboidal

I don't know what squamous cuboidals are but Sandra has been going through terminology that she has learnt for anatomy.

And every now and then she says things like "Squamous Cuboidal".

I go "Exuse me?"

She says "Squamous cuboidal."

I go "Oh. Just checking..."

I did try and help her understand ionisation; and that an acid is a proton donor.

A what? A proton donor....

What's that. Thats something that is giving out protons to all and sundry.

Oh. And why is an acid a proton donor?

Because when ionised it produced the H+ ion.

Yah? So....?

Well, Hydrogen is made of one electron and one proton. So if it becomes a anion then it no longer has an electron. And therefore is just a proton?

Just a proton?

Yup...

So something that when something happens to it, releases H+, is a proton donor, is an acid.

huh?

Oh.

Umm.

Could you explain that again?

.. It's in words that the magic is -- Abracadabra, Open Sesame, and the rest -- but the magic words in one story aren't magical in the next. The real magic is to understand which words work, and when, and for what; the trick is to learn the trick. ... And those words are made from the letters of our alphabet: a couple-dozen squiggles we can draw with the pen. This is the key! And the treasure, too, if we can only get our hands on it! It's as if - as if the key to the treasure is the treasure! ------- John Barth, Chimera
