My Desktop Background
The Carina Nebula is a large bright nebula that surrounds several open clusters of stars. Eta Carinae and HD 93129A, two of the most massive and luminous stars in our Milky Way galaxy, are among them. The nebula lies at an estimated distance between 6,500 and 10,000 light years from Earth.

Sacks Spiral (Prime Number Pattern)
The Ulam spiral, or prime spiral (in other languages also called the Ulam cloth) is a simple method of graphing the prime numbers that reveals a pattern. It was discovered by the mathematician Stanisław Ulam in 1963, while doodling on scratch paper at a scientific meeting. Ulam, bored that day, wrote down a regular grid of numbers, starting with 1 at the center, and spiraling out:

10 Baffling Medical Conditions
This list includes such gems as music-induced seizures, cold allergy, foreign accent syndrome and persistent arousal syndrome.
De Ideale Oliebol
Terwijl ik op zoek was naar het geheim van het oliebollenbakken vond ik het volgende:
"Tijdens het bakken worden de koolzuurbellen in het deeg opgewarmd waardoor ze uitzetten. Het soortelijk gewicht van de oliebol daalt daardoor en de bol komt bovendrijven. De helft die boven de olie uitsteekt wordt minder verhit dan de onderkant. Onderin de bol zet de CO2 dus meer uit, waardoor het soortelijk gewicht daar lager is dan bovenin de bol. De bol heeft dan aan een klein zetje genoeg om om te kiepen. "Het lijkt er op dat Annom en Kamielkaze het goed gezien hadden! De uitzending van de nationale wetenschapsquiz is trouwens 1 januari om 20:50 op Nederland 3.
