Alum - potassium aluminum sulfate - KAl(SO4)2 is one of the more popular crystals to grow. This may be because it makes a nice octahedral crystal that is visually appealling, or because it isn't terribly toxic. It probably also has a lot to do with...

Buoyancy is a simple concept. In order to float in water (or any other liquid), an object must displace a mass of the water equal to its own mass. The pressure exerted by the liquid on the hull of the boat (or any other object)...

Since time immemorial, humankind has debated the possibility that life could exist outside of our own planet. As our knowledge has improved through technological developments so has curiosity deepened about the cosmos. Extraterrestrial literally means life not originating on Earth. Keeping an open mind on...

The identification of chemical substances is both simple and complex. Every chemical, whether it is an element or a compound, has unique characteristics. It's kind of a fun puzzle to identify what you might have when given a set of 'mystery' substances in a chemical...

Modern Astrophysics/Cosmology is afflicted with a terrible malady, an illness so horrible it threatens to subsume and corrupt all the accomplishments of the last few centuries. This sickness is called Confirmationism, and its symptoms include summary dismissal of unfavorable experiments, the 'blackballing' of dissenting scientists...

The second postulate of Einstein's Special Relativity Theory states that the speed of light stays the same for every observer regardless of RF's (reference frames). Now, this somewhat conflicts with the laws of RF's because speeds of objects observed in difference RF's are always different...

Historically, most of the chemicals that were dealt with were inorganic compounds, and could be identified based on simple physical and chemical properties. Density, color, crystalline structure, physical state, melting and boiling points, reactivity with other known compounds - these were the tools that allowed...

This is the first article of a multi-part series into the realm of Einstein's Theory Of Relativity. In 1905, Albert Einstein developed the Special Theory of Relativity and ten years later, elaborated on that theory and published the General Theory of Relativity. Special Relativity is...

Our universe is a huge place, possibly infinite. within this vast space rein trillions upon trillions of stars, and they form, trillions of trillions of galaxies, clusters and supper-clusters of galaxies as fare as the eye can see. I have seen photographs where the galaxies...

A polyatomic ion is two or more atoms that are covalently bonded to one another and possess a charge. (The charge differentiates them from covalent compounds, which are neutral.) While the definition is nice to have, it doesn't help much when you're confronted...
