Many people throughout history have wondered about this simple question: Why is the sky blue? It is so simple yet so complicated. When the sky is blue and clear it is because molecules in the air reflect blue light from the sun more than they are reflecting red light. The sun has all the …
Despite thousands of years of gazing at the stars, we’ve never found another planet like Earth. Who would’ve thought looking inward would reveal the Earth is formed like an onion. A Complicated Planet Indeed When discussing the onion-like nature of the Earth, it is important to mention there is some debate as to what …
How are fossils formed? For fossil formation to take place a series of fortunate events must occur. If any part of the series is missing, we will never see the fossil! In fact, fossilization is a rare occurrence. Nature tends toward recycling. That includes just about everything from plants and animals to rocks and …
The goal of this article is to put some light on the difference between the types of statistical analysis. The two main basic branches in science known as statistics are Descriptive and Inferential statistics. These branches are tightly associated, but yet we can clearly establish a differentiation between them. Descriptive statistics This corresponds to …
School science laboratories seem to always be designed by accountants. They are generally poorly laid out and ill-equipped to serve their purpose. I have taught in many of these disasters and have designed other labs that have been a pleasure to teach in. It would be nice if price was not a constraining factor …
Corrosion is the tendency of metals to return to their natural condition, abandoning their current one, that is: the destruction or deterioration of a material because of chemical and/or electrochemical reactions. A chemical reaction or dry environment reaction can occur by the contact with vapors or gases, without the presence of liquids. With frequency, …
The very definition of the word calculus is derived from a mineral build-up and means “hard.” The Mathematical term of calculus describes a field that is a theoretical offshoot of algebra that attempts to define the way in which events will change over time. Calculus is used to determine the slope of a variable, …
The science of fluxions was Sir Isaac Newton’s terminology for the new field of science known today as calculus. Newton and German mathematician Leibnitz appear to have discovered the principles of calculus in about the same time; but Leibnitz published his work first. For years, there was friction between the two countries, England and …
The microscope is an important educational tool used in scientific research and education. It is used to produce a larger image of an object for projects ranging from medical discoveries to important educational training in schools across the nation. Microscopes use technology to allow humans to view objects as they could never be seen …
We all learn evolution theory in schools. Well, most of us do. However, what’s taught in schools is just basic. What most people — especially religious fundamentalists — do not want you to know is that evolution theory can very naturally explain human nature. It’s not taught in school. So I’ll tell you here. …
