Step-by-step explanation:
1. PYTHAGORAS:
Pythagoras is most famous for his concept of geometry. It is believed that he was first to establish that the sum of the angles of a triangle is equal to two right angles and that for a right-angled triangle the square on the hypotenuse is equal to the sum of the squares on the other two sides.
Although the last mentioned theorem was already discovered by the Babylonians, Pythagoras was first to prove it. It is also believed that he devised the tetractys, the triangular figure of four rows which add up to ten, which according him, was the perfect number.
Pythagoras also discovered that musical notes could be translated into mathematical equations was when he passed blacksmiths at work one day and thought that the sounds emanating from their anvils were beautiful and harmonious and decided that whatever scientific law caused this to happen must be mathematical and could be applied to music. He went to the blacksmiths to learn how the sounds were produced by looking at their tools. He discovered that it was because the hammers were "simple ratios of each other, one was half the size of the first, another was 2/3 the size, and so on".
This legend has since proven to be false by virtue of the fact that these ratios are only relevant to string length (such as the string of a monochord), and not to hammer weight.
However, it may be that Pythagoras was indeed responsible for discovering the properties of string length.
Pythagoreans elaborated on a theory of numbers, the exact meaning of which is still debated among scholars. Another belief attributed to Pythagoras was that of the "harmony of the spheres". Thus the planets and stars moved according to mathematical equations, which corresponded to musical notes and thus produced a symphony.
2. ALBERT EINSTEIN:
Einstein was not nearly interested in Math as he was in physics. At university he did not really apply himself to the mathematics exams. He still passed them though, but perhaps not as well as he could have (and here the false myth that Einstein failed math at some point).
He later regretted it as indeed math was fundamental to his own physical theories.
One thing Einstein contributed to was his notation for tensors and sums, which greatly simplifies tensor calculus and summations (which come up a lot in General Relativity) .
