No. I'm not really talking about, thinking about the current FBI/Apple issue and, instead, am trying to be more fundamental and look ahead one step, say, the next step after the FBI/Apple, uh, maybe call it a pissing match.

Since no doubt governments never were able to find a fast way to factor a product of two large prime numbers, they never did have "control" of encryption.

Why? Has the FBI found a fast way to factor any product of two large prime numbers? Until they do, what the FBI wants is not always what the FBI can get, Congress or not.

Nice list. I saw emphasis on control, optimization, numerical methods, and applications. Nice. And, sure, PDE's stand to get more.

Yes, and once students discover this, then good luck in getting students in the class! And, if regard the material on differential equations as essentially nonsense, then good luck getting NSF grants for research in the subject! Actually, c

Here's a related question: Supposedly now the CO2 concentration is about 400 parts per million (maybe by weight) and up from ballpark 200. Okay, how much CO2 is 200 parts per million in the atmosphere? Then, how does that much CO2 c

I'm still trying to understand: I know, CO2 is a greenhouse gas: So, light from the sun warms the surface of earth which, then, from Planck black body radiation, radiates more infrared light. As we can see from our exhaled breath,
