Since normal air is primarily nitrogen, with a little bit of oxygen and traces of some other gases, it might appear that nitrogen does not need discovery. After all, this is what people are submerged in throughout their lives. But science needs to identify and...

On earth there are many things humans have spent decades or even centuries trying to figure out. The world is full of amazing things. Science and chemistry can often help explain many things that seem too remarkable to be true or too complex for some...
A review of the great women astronomers
By: Maria C Collins
Astronomy is apparently a man’s world. Those asked to name great astronomers would undoubtedly name several men, but would have difficulty naming a single woman astronomer. There have been many female astronomers who contributed to astronomical knowledge and method, but like women in other...
Chemistry: Why air is colorless
By: Shaheen Daad
In response to the question of why air is colorless, the chemist provides a very simple answer. It is only because the gases that make up air are all colorless. There might be some trace gases like chlorine and nitrogen dioxide, which are colored yellowish...

In just a few billion years the closest galaxy to Earth, the Andromeda Galaxy, and the Milky Way will collide. In astronomical terms it will be a clash of the titans; but in human terms it is a slow process indeed. The two galaxies are...

Understanding how boomerangs fly has been a quest for scientists for thousands of years, despite the fact that the boomerang has been in use for over 10,000 years. Recent aerodynamic discoveries have made understanding the principles behind its flight easier to grasp, as well...
