07-2021 Alan Turing is mine !

But who was Alan Turing ? Why is he so famous ?

If you are not too much into computer science, AI and stuff like that, you may as well assume that Alan Turing is the God of computer science. The proof, if required, comes from the fact that the biggest prize/award in Computer Science is named after him, and also the fact that
the smallest model of a computer was developed by Alan Turing !

But his life had a pitiable end. See : the man who knew too much .

How did I get to own Alan Turing ? I simply managed to get a 50 GBP note issued by the bank of England on 23 July 2021. Details are here :: the new 50GBP note .

I thank my dear friend Christian CHEVALIER who procured this treasure and mailed it to me promptly. Mille merci, cher ami.

I can now claim proudly, Alan Turing is mine !

Vedic maths as a business model ? Why not try witchcraft ?

I received today an invitation for a weird event to discuss ways of making money using Vedic mathematics.


To make their point more tempting and attractive, they have also added a suggestive picture in the invite. The point is, many gullible and greedy people, particularly parents, are expected to bite this bait and fall into this trap.

“Look before you leap”, is a very popular idiom. I must add — “Look, before you make your children leap”. Before you sink your money and drown your children, look at some sane advise from a mature teacher of mathematics:

If making money is your aim, why not try witchcraft ? It can fetch you much more money than mathematics and make you rich, faster.

Use your commonsense, and you be the judge.

Who says maths is boring ?

Casting pearls before swines.

Today (22 December) happens to be the birth anniversary of Srinivasa Ramanujan,
a brilliant mathematician who created some incredible mathematics which is
used in a wide variety of fields. Some years ago, after several proddings, the Government of India declared 22 December to be the national mathematics
day. Predictably, the celebrations stopped with that declaration. We continue to bask in our ignorance and indifference, given that many of our so-called mathematicians and institutions remain blissfully ignorant of this great mathematical genius. We do not even know how to celebrate or worship Ramanujan, much less understand or appreciate him. Year after year, I have tried to convince my neighbourhood schools to spend some time talking about mathematics seriously (other than routine classroom lectures). I even compiled and made available on the web, a lot of material about Ramanujan. But no one even noticed it. I have not succeeded in making any dent in their mindset. Maybe, two can lead a horse to the water, but two hundred cannot make the animal sing, if it is a donkey or a swine.

Here are some more discoveries I made:

  1. Where ignorance is bliss
  2. Where ignorance is bliss … a
  3. The sequel to a sequel
  4. Ramanujan deserves more than this

  5. My own humble tribute to the genius, in my own little way:

  6. Remembering Ramanujan
