Brahmagupta was a 7th century Indian mathematician and astronomer who made important contributions to mathematics. Some of his key achievements include developing the concepts of zero, negative numbers and the use of algebraic formulae to solve indeterminate equations. He authored two important texts - Brahmasphutasiddhanta and Khandakhadyaka - that had significant influence on mathematics in India and the Islamic world.

4. • Albert Einstein, the renowned
physicist, is remembered for his
theories on nuclear power, and
his revolutionary concept
concerning nature of light. He has
made significant contributions to
the field of mathematics, physics,
and science.

5. Einstein’s Contribution to
Mathematics
• While Einstein was remembered for his
contributions to physics, he also made
contributions in mathematics. He
contributed several equations to calculus
and geometry, ten of which are called the
Einstein Field Equations.

6. Einstein field equations
• The Einstein field equations (EFE; also known
as "Einstein's equations") are the set of ten
equations in Albert Einstein's general theory of
relativity that describes the fundamental
interaction of gravitation as a result of space-
time being curved by matter and energy. First
published by Einstein in 1915 as a tensor
equation, the EFE equate local space-time
curvature with the local energy and momentum
within that space-time.
