The brain has been studied by many, but we still don’t know enough about it even today. Certain diseases such as severe forms of epilepsy can be cured only by separating the two hemispheres of the brain. The study of people who have undergone such operations can give us important information about how the brain functions.

Half century ago, it was suggested that oxygen and carbon crystallized inside the cooling cores of white dwarfs, also called degenerated dwarfs. As a result, the generated heat slows down the cooling of the star. In 10 million years, our Sun is going to turn into crystalline white dwarf of this type. In January 2019, a conference of the American Astronaut Society was held in Seattle where scientists from Britain, Canada and the United States confirmed this paradoxical model of stellar evolution.

A light bulb is a little glass bulb filled with nitrogen or argon, a thin wire (called a tungsten filament) and a tin base. It’s not surprising that the cost of this mass-produced light bulb is available at a low price. But incandescent bulbs are very wasteful; o more than 4% of the total energy used is actually converted into light.

Just a few hundred extra calories per day can lead to serious health problems that can be avoided by not putting on extra weight.
