Bhāskarāchārya / Bhāskara II (1114–1185) was an Indian mathematician and astronomer.
Among his many achievements are the following:
1. He was the first person to explain that when you divide by zero, the result is infinity.
2. He was also the first person to note that a positive number has two square roots - a positive and a negative one.
3. He described the principles of differential calculus 500 years before Leibniz and Newton. (He definitively came up with Rolle’s theorem half a millennium before Rolle himself.)
4. He calculated the length of the rotation of the earth around the sun to 365.2588 days - he was just off by 3 minutes.
Intriguingly, his treatise on arithmetic and geometry, Līlāvatī, is named after his daughter. He addresses her as an eager student:
Oh Līlāvatī, intelligent girl, if you understand addition and subtraction, tell me the sum of the amounts 2, 5, 32, 193, 18, 10, and 100, as well as [the remainder of] those when subtracted from 10000.” and “Fawn-eyed child Līlāvatī, tell me, how much is the number [resulting from] 135 multiplied by 12, if you understand multiplication by separate parts and by separate digits. And tell [me], beautiful one, how much is that product divided by the same multiplier?
These invocations have led some to surmise that Līlāvatī, too, was a mathematician.

well my math teacher never talked to me that way
As for the results of your current work, be entirely indifferent. Nobody can ever guarantee results. If there are some — good; if none result—there is no harm; they will emerge later, in another place under other conditions.

As for the “solitary confinement of the mind,” my theory is that solipsism, like other absurdities of the professional philosopher, is a product of too much time wasted in library stacks between the covers of a book, in smoke-filled coffeehouses (bad for the brains) and conversation-clogged seminars. To refute the solipsist or the metaphysical idealist all you have to do is take him out and throw a rock at his head: if he ducks he’s a liar. His logic may be airtight but his argument, far from revealing the delusions of living experience, only exposes the limitations of logic.

Pablo Picasso hidden portrait found beneath famous painting ‘The Blue Room’
A hidden portrait has been unearthed beneath Pablo Picasso’s masterpiece “The Blue Room”.
Art experts using infrared technology on the painting revealed a man wearing a jacket, bow tie and rings and resting his bearded face on his hand.
Scientists have confirmed that the artwork was created just before “The Blue Room” during the Spanish painter’s early 1900s ‘blue period’, in which he focused on monochromatic paintings in blue shades.
“It was one of those moments that really makes what you do special,” said Patricia Favero, conservator at the Phillips Collection.
It remains unknown who the mystery man in the ‘lost’ painting is but specialists are “still working on answering that question”. The possibility of a self-portrait has been ruled out, with Paris art dealer Ambrose Villard one contender.
This hidden portrait has been revealed beneath ‘The Blue Room’
The existence of another painting below the surface of “The Blue Room” was first suspected in 1954 when conservators noticed that brushstrokes did not match the composition.
A “fuzzy image” was revealed in the 1990s and details became clearer with advanced technology in 2008, when the painting of a woman bathing in Picasso’s studio was turned on its side.
Research is continuing with the aim of identifying the colours of the portrait and recreating a digital image of it.
Experts are unsurprised that Picasso re-used his canvas. Curator Susan Behrends Frank told AP that the artist “could not afford to acquire new canvasses every time he had an idea that he wanted to pursue”.

“He worked sometimes on cardboard because canvas as so much more expensive,” she said. “When he had an idea, you know, he just had to get it down and realise it.”
Hidden paintings have been found under Picasso’s work before. An analysis of “La Vie” proved that Picasso had re-working the image and a moustached man was discovered under “Woman Ironing”.
