Zinc is a kind of metallic chemical element. It is considered to be a transition metal, similar to nickel and mercury. It has the chemical symbol of ZN with an atomic number of 30. In its pure form it has a kind of light blue color. It tends to be quite brittle at room temperature but, once it is...
Magnesium (with a symbol of Mg) is a metallic chemical element. It has an atomic number of 12, and—like calcium and barium—is considered to be an alkaline earth element. Magnesium was discovered in1808 by the scientist Sir Humphry Davy. However, some believe Davy only found magnesium oxide, and...
Sodium is a mineral, and one of the ten most abundant minerals on Earth. Its chemical symbol is “Na” which is the abbreviation of natrium, a Latin word. It has the atomic number of 11. It was first isolated in 1807 by Sir Humphrey Davy, who “discovered” it when he ran an electric current through...
Nitrogen is a chemical element that is crucial in sustaining the Earth’s atmosphere and all life. In fact, about 80% of the atmosphere is made of nitrogen. It plays, literally, such a big part in life that scientists say that it is the seventh most abundant chemical in the universe....
Sulfur is a chemical element with the symbol “S” and an atomic number of 16. It is considered to be a non-metal. It has a number of different ions, resulting in Sulfites (which are used in food processing) and sulfates (which are used in manufacturing). Sulfur can also be found in living organisms...
Some things might have been better off not being invented. Now we're not denying that these come with some good ... convenience, connectedness, etc. We're just saying... sometimes the bad seems to outweigh the good.
Steel is an ideal construction material—it is easy to shape, strong, and easy to manufacture. It can also be remelted and recycled, making it very “sustainable” and eco-friendly. However, like all metals it is prone to rust and corrosion, especially when it is exposed to the elements. To solve...
When you run experiments, there's inherently an element of the unknown. After all, we're trying to figure out things we don't know. And sometimes, things go wrong. FATALLY WRONG! Here are some of the most interesting, most intriguing, and sometimes most horrific, experimental deaths we've ever...
Those who are inspired by a model other than Nature, a mistress above all masters, are laboring in vain. - Leonardo Da Vinci Biomimicry - The practice of developing sustainable human technologies inspired by nature. Sometimes called Biomimetics or Bionics, it's basically biologically inspired...
