Two other European companies have plans to unveil solar-assisted cars, too. Some experts have theorized that if we were to lay down a gigantic number of solar panels over a wide area, we could absorb enough sunlight to power entire cities, effectively ending our energy crisis. The problem ...
Today, some scientists question the validity of the story. They argue, for example, that the wooden horse may have been a battering ram used to break down the gates of Troy. But oral historians, who apparently wanted a grander tale to tell, altered the facts and injected the idea of an...

The atomic weight is the average mass of all the element's isotopes. It is the average number of all the protons and neutrons in the nucleus. Generally, the atomic mass increases as you move down or across each group or period. Of course, there are exceptions to this rule. Check out ...
Nanotechnology is a very promising field to the medicinal and pharmaceutical sectors, hence, it plays an important role in enhancing humanity’s quality of life. Nanotechnology has many applications in the medical sector, including diagnosis and therapeutic. However, therapeutic uses are considered the...
X-rays can kill. At the very least, they can give you cancer, which also kills. If you do not fully understand the dangers of ionizing radiation, and are not competent enough to handle voltages exceeding 50,000eV do not, under any circumstances replicate what I have done here. ...
