The proof of Sum of Square Numbers!
This is NOT a proof, but it’s still very beautiful and good for intuition.
That is a beautiful illustration.
It’s like that animated triangle thing about Pythagorean theorem. It doesn’t teach you how to do a thing, it shows you how and why the thing is what it is.
Sorry I havent been posting much! Im student teaching this semester and have been crazy busy.

Today Google celebrates Shakuntala Devi’s 84th birthday. She was popularly known as the “Human Computer”, was a child prodigy, and mental calculator. She passed away on April 21 2013, she was 83 years old. Her achievements include:
- In 1977 in the USA she competed with a computer to see who could calculate the cube root of 188,132,517 faster (she won). That same year, at the Southern Methodist University she was asked to give the 23rd root of a 201-digit number; she answered in 50 seconds. Her answer—546,372,891—was confirmed by calculations done at the U.S. Bureau of Standards by the Univac 1101 computer, for which a special program had to be written to perform such a large calculation.
- On June 18, 1980, she demonstrated the multiplication of two 13-digit numbers 7,686,369,774,870 × 2,465,099,745,779 picked at random by the Computer Department of Imperial College, London. She correctly answered 18,947,668,177,995,426,462,773,730 in 28 seconds. This event is mentioned in the 1982 Guinness Book of Records.
- In 1977, she wrote The World of Homosexuals, the first study of homosexuality in India.
Happy birthday Shakuntala!
Also from wiki:
In 1977, she wrote The World of Homosexuals, the first study of homosexuality in India. In the documentary For Straights Only, she says that her interest in the topic came out of her marriage to a homosexual man and subsequent desire to look at homosexuality more closely in order to understand it.
The book, considered “pioneering”, features interviews with two young Indian homosexual men, a male couple in Canada seeking legal marriage, a temple priest who explains his views on homosexuality, and a review of the existing literature on homosexuality. It ends with a call for decriminalising homosexuality, and “full and complete acceptance—not tolerance and not sympathy”.
