All right, I will assume this forum is my living room and the posters are my parents and kids.

Ok papa, sorry!

sagarika reveals her true colors... There is no unanimity over Modi either in NDA or BJP: Sagarika Ghose LK Advani's resignation from all party posts and the withdrawal of the same a day later have been variously interpreted in political circles. Some have called it an abject surrender to Modi and t...

I think something is amiss here that we don't know yet. One thing that is interesting is that RNS had consulted him before announcing Modi as Chief campaigner. NK's team even announced that this was internal matter for BJP. Only after Advani episode they have turned up the heat. Why? I think it is ...

I prefer sage that can be obtained from http://www.sagemath.org for experimentation with Discrete Math, Graphs, Combinatorics, Logic, Linear Algebra, and {Number Theory and Crypotgraphy}.

@abhishek_sharma: I don't have problems about any particular mathematician - after all we all are limited by the knowledge we posses. And we need experts in any particular field and its subfields - otherwise the field wouldn't grow. I grew up with lots of good and excellent mathematicians. I am talk...

Yes, I know that linear algebra is very important for CS. But I took that course in the Math dept, and they discussed the properties of rings and fields for a while....it was just theorems and lemmas .... There was that red-colored book on linear algebra...what is its name? I will try to find it. Y...

kasthuri

Yes to Horn and Johnson. Instead of jumping straight into that book start with "Linear Algebra Done Right" which is quite good in spite of the snarky title. All theorems are proved with no recourse to determinants purely algebraically. All one needs is mathematical induction and maturity ...

Actually they do a lot of hand-waving ...but they claim that they are using mathematical ideas (like wavelet analysis, geographic profiling) for solving crime-related problems.

The Paradox of the Proof Thank you. It was really interesting to know about Mochizuki and his work. As you may be aware, same happened with Andrew Wiles's proof of FLT (about 300 pages long).

Well I’m neither so willing to learn. I did not understand that quote from Ramanujam, what does it mean. My take away is that reality at the QM level is very mysterious. AFAIK there is only one reality. Both QM & CM are part of that reality but not separate ‘aspects’. There is only one reality,...

kasthuri

It is what it says about the nature of reality that blows the mind. Nature of reality cannot be confined merely to a set of equations. The right word would probably be "an aspect of reality" Ramanujan often said "An equation for me has no meaning, unless it represents a thought of Go...

kasthuri

There is also a theorem or two that prove that Quantum mechanics cannot be derived from classical mechanics (i.e. as an extreme case). Why do we expect QM to be derived from CM? Do we have any linear axiomatic basis for these things? I understand QM as an extension of CM from an intuitive perspecti...
