Yes, I went to grad school in math. The first test was a pop quiz in real analysis and was about the little axiomatic set theory the prof had started the course with. When the prof handed back the papers, he'd given me a zero. At the

Right. I didn't say, suggest, or believe that the extra cost of restaurant food was due just or mostly to the initial, one-time costs of the startup. Instead I wrote > all before hiring any workers to get the food ready for customer

The OP starts to make clear why my home cooking is so much cheaper than restaurant food: The ingredients in my version of pizza cost less than $1 per pizza. For pork BBQ, that's about 25 cents per ounce, final, cooked, lean, ready to

Ah, I left out a lot! But I included enough that you could extend to some relatively deep parts! But among what I omitted was determinants. So, I couldn't mention your points! To me the one easy approach to determinants is to say that

I'll get you a start here: For the graphical part, start with, say, (3,7). Regard that as the coordinates in the standard X-Y coordinate system of a point on the plane. So, the X coordinate is the 3 and the Y coordinate is the 7.

How much CO2 causes how much warming? That was the core question of the studies I mentioned.

CO2 is transparent to visible light: E.g., pop open a brewski and observe that can't see the CO2 and that it does not cast a shadow. CO2 absorbs photons in three narrow wavelength bands, one for each of bending, stretching, and twisti

My guess at what in the early days of personal computing, i.e., ~1985, really caused the rapid growth: Replacing the typewriters. The labor of using typewriters was enormous. So, replacing a typewriter with just a PC, maybe with only a fl

Yup, maybe that looking alike is called convergence . Apparently a big instance is eyes, apparently developed several times with surprisingly close to the same design. Pigs, rhinos, hippos, ..., triceratops all look much the same to me!

My understanding is that eggs and no-eggs are not as different as might be expected. After all, the no-eggs still have eggs but, just, don't lay the eggs or let us make French toast, custards, or omelets! Maybe a key issue woul

Thanks. Okay, good to see that quantum mechanics defines its use of correlation as <(a - <a>) (b - <b>)> / (sigma_a sigma_b) Good. Glad to see the actual definition. That is, with usual quantum mechanics notation,
