Metalworking and manufacturing processes: What is the shearing process
By: Rex Coker
There are three different methods of shearing metal in manufacturing. Metal shearing can be done at all three stages of making the products length, width. Other methods of cold shearing are used by pipe and stamping facilities. Steel mills use many different shearing methods...
Isaac Newton's Three Laws of Motion
By: K.P. Arnolds
Isaac Newton was one of the most famous physicist that ever lived. Even though he was very educated in many subjects including math, astronomy, alchemy, and theology, he is most famous for his contributions to physics. His most famous was Newton's Laws of Motion...

Crystals are a highly organized form of matter. This is obvious to anyone who has looked at crystals, as they naturally tend towards particular geometric shapes. Each crystalline compound has a characteristic form, regardless of its size. This rigid organization continues down to the placement...

The periodic table is a tool used in chemistry which lists and ranks elements - gas and solid - by grouping according to weight and atomic number. Conceptions of science were altered by the development of the periodic table and this is still is a...
Middle school chemistry projects: Exploring the properties of sulfur
By: Ernest Capraro
When introducing the elements, it is always more fun for the students if they have the opportunity to examine a few rather than just hearing about them. Sulfur presents an excellent opportunity, as it has a fairly unique set of properties, without being terribly hazardous...

The science of quantum theory is a socially constructed account of the universe, and just one of many possible accounts. In fact, all knowledge of the universe is socially constructed and complimentary, allowing physicists to connect observations in the everyday world of the laboratory with...
Why the Search for Extraterrestrial Intelligence (SETI) may not be a good idea
By: James Boyd
Steven Hawking recently suggested that a meeting between humans and an extraterrestrial species might not turn out well for the humans. As an example he used the encounter between the native inhabitants of the Americas and the invading Europeans. It went badly for the natives...
Examples of chemical changes
By: Ernest Capraro
Chemical changes come in many forms, but we teach that there are certain clear signs that can indicate that a chemical change has taken place. Those signs, while not always absolute proof of a chemical change, provide an excellent way to categorize a few examples...
Is there a Fundamental Subatomic Particle in Physics
By: Ct Yankee
Could there be a basic particle? We call this one of the “dirty questions” in physics. That's because the answer only makes sense if a whole set of qualifications are applied to the question. In order to support an affirmative answer, the shortest set...
