credits von Seidel with discovering, in 1847, the crucial analytic concept of uniform convergence, while analyzing an incorrect proof of Cauchy's.
In 1857, von Seidel decomposed the first order monochromatic aberrations
into five constituent aberrations. They are now commonly referred to as the five Seidel Aberrations.
The lunar crater Seidel
is named after him.
The Gauss–Seidel method is a useful numerical iterative method for solving linear systems.

Imre Lakatos
Imre Lakatos was a Hungarian philosopher of mathematics and science, known for his thesis of the fallibility of mathematics and its 'methodology of proofs and refutations' in its pre-axiomatic stages of development, and also for introducing the concept of the 'research programme' in his...

Aberration in optical systems
Aberrations are departures of the performance of an optical system from the predictions of paraxial optics. Aberration leads to blurring of the image produced by an image-forming optical system. It occurs when light from one point of an object after transmission through the system does not converge...
