Why is cheese blue
Noble blue cheese is a popular delicacy, and Stilton is one of the most famous varieties of this product. It is prepared in the counties of Derbyshire, Leicestershire and Nottinghamshire to strict standards that have been passed down from generation to generation. At the same time, the village of Stilton itself, in honor of which the cheese was named, is located elsewhere - in the county of Cambridgeshire.
And the cheese owes its noble color to mold from the penicillin culture. The video channel Discovery tells about where it comes from and what is the secret of an old cheese recipe.

In its video, Discovery talks about the difficulties engineers faced when launching a monorail in Mumbai, India, how it works and how safe it is.

How uranium is produced
German chemist Martin Heinrich Klaproth first obtained uranium back in 1789, but for almost a century and a half this discovery was not given much importance. Only in 1938, scientists learned how to split its atoms to obtain energy. An assembly of uranium the size of a log can provide heat to a hundred homes for a year. But its production is fraught with many dangers. Watch in this video how uranium is mined, why groundwater is frozen in the process, and how ore is turned into nuclear fuel.
