Arbitrary Faces

I am doing sample caricature these days. I have bought Faber-Castle sketching pencils and using these I have drawn typical face shapes.
I have to perfect these in real photographs. Musicians and politicians. Indian politicians are the second set of people I shall do caricatures of
I may do crayons also. After I perfect the above.

My favourite five internet destinations

My favourite five internet destinations are :-

  1. Google news
  2. Wolfram, emathhelp, symbolab
  3. Quora
  4. My bank site(SBI)
  5. Microsoft office
Flowcharts, bollywood music, caricatures, biography(not works) of mathematicians are frequented sites from Google search.

#PythaShastri Expression for Pi (π)

I got an expression for π. It was tough. It was daunting.
There are very few expressions for π.
So, here is my expression:-
π = 3√3(1 - 1/3 - 1/4 + 1/6 + 1/7 - 1/9 - 1/10 + . . . . . . . .)

#PythaShastri Why Euler was the greatest ?

Primes
Euler

Euler multiplied (prime number)/(nearest multiple of 4) as a series and declared it was pi by 4.

Euler took the Riemann Zeta function of s = 1 and made the term in the denominator if prime, -ve or +ve depending on a logic and declared it was pi by 4.

He made 1/(1- prime to the power -s) multiplication series and declared it as Riemann zeta function.

I felt the first statement 15%; the second 15%; and the third 20%. But no pen. Just thinking in the direction.

Euler-Mascheroni constant
Euler

Euler was able to express the real meaning of gamma and gave two methods (at least) for its calculation.

I felt 1%.

Euler did much much more. He was a genius machine.
