بل أن تحافظ على صفاء مزاجك أثناء الانتظار

Patience is not about waiting, but about maintaining a good temper while waiting

Some people have a scope of view of radius zero and call it their point of view.

David Hilbert – Scientist of the Day

David Hilbert, a German mathematician was born on Jan. 23, 1862, probably in Königsberg, which was then part of Prussia.

One of the most influential mathematicians of the late 19th and early 20th centuries, now in Live2D!! (Created by Junferno using public domain images courtesy of Wikimedia Commons).

By the late nineteenth century, many other assumptions and proofs in Euclid's work were being questioned. Some argued that it was time to start from scratch by rebuilding geometry on new foundations. The task was taken up by David Hilbert, who was to become the most influential mathematician of the early twentieth century. His resulting book, Grundlagen der Geometrie (The Foundations of Geometry), published in 1899, is now recognized in its clarity of reasoning as the rightful heir of Euclid’s Elements. A mathematical best-seller, its impact was immediate.

In his position as the discipline's foremost spokesperson, Hilbert now demanded that all of mathematics – and indeed the sciences – be made as bulletproof as his new geometry. In 1880, the famous physiologist Emil du Bois-Reymond had declared there were some questions (he called them 'world riddles'), such as the ultimate nature of matter and force, that science could never answer. 'Ignoramus et ignorabimus,' as he put it: 'We do not know and will not know.'

Hilbert was having none of it. In 1900 he sounded his opposition to du Bois-Reymond's pessimism, denying that there were any such limits to knowledge. Every question had a definite answer, he argued, even if what that answer showed was that answering the original question was impossible. ... ‘For us there is no ignorabimus, and in my opinion none whatever in natural science,’ Hilbert was to thunder even thirty years later. ‘In opposition to the foolish ignorabimus our slogan shall be: Wir müssen wissen – wir werden wissen.’

[This] would become the epitaph on his gravestone: We must know – we will know.
