Hey! Nice list!

ii is a very good practice, keep it up!

iii) some people say that this is a sign of a rebel.

I share v with you.

viii) Nice! I do not really like Geography, though.

ix) Sometimes, that is me too.

x) I do that almost every day. It's not my favorite though.

I'd like to see bobbym's list, though

I learnt that if an automaton with exactly n states accepts all strings of length n or less, then it accepts all strings.

How about a language called kannan-speak? The programs would read like how my algebra teacher teaches in the class.

Programs would begin with a recall. End with a joke. Variable declarations would read like "Notation: n in Integers". The program body would be divided into Lemmas and Theorems

Are you asking us about esoteric programming languages?

Learning English can be hard. It can be taught through thorough thought, though.

Oh yes, that totally works. Thank you

Let f be a continuous function on the reals. Furthermore, assume that f is differential everywhere.

For all real x and y (such that y != 0), the following holds: f(x-y) = f(x)/f(y)

Assume that f'(0) = p

Can we use this to determine f?

I don't think that is a substitute for the prime number theorem. The prime number theorem is an assymptotic bound. It can be calculated way faster than actually counting the primes

Hey bobbym;

Here is a fun video about this.

That makes sense. I already live in the Riemann Sphere, though.

Alokananda suggested that another possiblity is an autoimmune disease where some other substance emulates TSH requiring the need for actual TSH

Hi Chris2, bobbym, and Agnishom,

The Answer 'glaucoma' is correct. Splendid, Chris2 and bobbym! I haven't come across any problem/puzzle/teaser/paradox in Medicine, as far as I know. Only Questions/Answers, Agnishom.

I came across one puzzle in medicine. I have regular levels of T3 and T4 hormones, but a low level of Thyroid Simulating Hormone. Why should that be?

Are you bored of real doors? Just having to open and walk through them all the time?

That's a large program. What do you do when there are 30 variables?

I use programming languages to solve these problems.

Yes, you could also use a constraint solver to do this for you.

and what do you think of my dating advice in #162?

I did not do well enough to get an AIR.

What do you think about my comments on how horrible JEE is?

Transitivity should be a part of the axioms of a partial order.
