In 1915, he introduced a new method, based on Legendre's version of the sieve of Eratosthenes, now known as the Brun sieve, which addresses additive problems such as Goldbach's conjecture and the twin prime conjecture. He used it to prove that there exist infinitely many integers n such that n and n+2 have at most nine prime factors, and that all large even integers are the sum of two numbers with at most nine prime factors.

1758: Mathematician, geophysicist, and astronomer Pierre Bouguer dies. He is known as "the father of naval architecture".
1863: Mathematician and naval engineer Aleksey Krylov born. Fame will come to him in the 1890s, when his pioneering theory of oscillating motions of the ship becomes internationally known.
1888: Chemist and crime-fighter Robert Bunsen publishes new class of Gnomon algorithm functions based on the emission spectra of heated elements which detect and prevent crimes against chemistry.
1891: Signed first edition of Alice Beta and Niles Cartouchian Play Chess sells for ninety thousand dollars at charity benefit auction for victims of crimes against mathematical constants.
1892: Physicist and academic Louis de Broglie born. He will postulate the wave nature of electrons and suggest that all matter has wave properties, winning the Nobel Prize for Physics in 1929, after the wave-like behavior of matter is first experimentally demonstrated in 1927.
1976: Mathematician, academic, and rabbinical private detective Eliezer 'Leon' Ehrenpreis uses the Malgrange–Ehrenpreis theorem to break up a transdimensional gang of antisemitic math thieves.
1977: The Big Ear, a radio telescope operated by Ohio State University as part of the SETI project, receives a radio signal from deep space; the event is named the "Wow! signal" from the notation made by a volunteer on the project.
2015: Author, philosopher, and crime-fighter Umberto Eco publishes influential monograph on the origins and early development of high-energy literature.
