The Bakhshali manuscript is written by Jaina mathematicians, which describes a theory of the infinite containing different levels of infinity, shows an understanding of indices[disambiguation needed], as well as logarithms to base 2, and computes square roots of numbers as large as a million correct to at least 11 decimal places
Aryabhata writes the “Aryabhata-Siddhanta”, which first introduces the trigonometric functions and methods of calculating their approximate numerical values. It defines the concepts of sine and cosine, and also contains the earliest tables of sine and cosine values (in 3.75-degree intervals from 0 to 90 degrees)

Jacob Bernoulli discovered this constant by studying a question about compound interest:
An account starts with $1.00 and pays 100 percent interest per year. If the interest is credited once, at the end of the year, the value of the account at year-end will be $2.00. What happens if the interest is computed and credited more frequently during the year?

During the second half of the thirteenth century, gunpowder became known in Europe, perhaps introduced from China through the Mongols. "Knowledge of the explosive properties of salpetre, sulphur, and charcoal seems to have been perfected [in China] about 1000 " (Crombie 1952:192). The evolution of the gun in China appears to have been, first, bamboo flame throwers, then metal tubed flame throwers, then arrow throwers, and, after 1280, ball throwers (O'Connell 2002:113)
1512, Nikolaus Kopérnik, better known as Copernicus, circulated a manuscript, the Commentariolus, which hypothesized that the Earth was a planet and planets revolved in circles and epicircles around the Sun, that the Earth rotated daily, and regressions in planetary orbits were explained by the Earth's motions (Park 1990:143). The problem, as he saw it, was to save the appearance of the phenomena with an hypothsis which was compatible with the principle of physics that hypotheses be founded in the truth of nature, and to demonstrate that to reject this hypothesis meant that the appearances were not saved.
