Beginning Calculus: Rate of Change

Rate of change in calculus is a series I have been wanting to do for a while. If you are a student and just starting then your in the right place. This is the very beginning of calculus and where you want to start your learning. Since there are so many topics in school that require some calculus, I felt it was important to get some basics up here for you.

Beginning Latex : Tutorial For Beginners

So you are writing a paper and you need to display formulas or math in it. Then this quick beginning Latex tutorial is for you. Your paper needs to be accurate and look good. You then go to your favorite word processor to type things out. It is then you discover, maybe for the first time, that regular text editors can not do math very well. You may be trying to display physics equations, biology genes, or chemical formulas.

Whichever it is, you realize you have to be super creative to even approach the accuracy that you want. At this point you will probably start asking around or researching the best way to do this. Well let me tell you folks, there is a better way.  This is when most people find out about the wonderful Latex typesetting environment. Read on and I will explain as simply as I can about Latex.

18 Basic Chemistry Concepts

Basic Chemistry Concepts For Beginners

This is an introduction to the fundamental concepts of chemistry. It is not meant to be an exhaustive resource but just something that you can look at to make sure you understand what is going on. This is ideally for those students just beginning with chemistry whether in high school or college. I am including basic concepts as well as some example problems. If you would like a primer on Biology then start at this post http://sciencebyjason.com/2016/03/purpose-dna-biology/

What Are Star Classifications And Their Life Cycles

What are Star Classifications

Have you ever wondered about star classifications ? Stars are classified based on their temperature, but started out being based on only their spectra. This classification process started in the 1890s by Edward Pickering at Harvard and was finished in 1901 by Annie Cannon, who worked for Pickering. Cannon reorganized what Pickering started in the classification that we know today. The classification is as follows "O B A F G K M" that goes from the hottest stars to the coolest stars. These classifications are further subdivided in categories "0-9" where 0 refers to early in that star and 9 refers to a late type of star.

This classification is now called the Harvard Spectral Classification. Type O stars and Type B stars are both blue-white hot stars, but Type O stars are the hottest stars. Type A stars are white stars that give off Balmer absorption lines in early A stars. Type F stars are yellow-white stars. Type G stars are yellow stars like our Sun. Type K stars are cool orange stars, whose spectra is dominated by metal absorption lines. Type M stars are cool red stars, whose spectra is full of molecular absorption lines. The Sun is classified as a Type G2 star with a surface temperature of 5777 Kelvin. These spectral classes also relate to the surface temperatures of the stars.

What Is The Purpose Of DNA In Biology?

Purpose Of DNA

Biology is one of those subjects that take a while to get used to. In college my classes were all full of prospective medical students and the occasional pharmacy major. So each class was full of hard workers. Despite having so many people around that were eager, some topics were hard to fully understand at first. DNA was one of these.
It stands for deoxyribonucleic acid. It is one of the first topics a biology student encounters that is unclear. It isn't really unclear though. It just does a lot of complicated things. It holds much of our biological data and it determines who you and successive generations will become. It is made up of the well known double helix you see plastic models of in all the labs.

How Modern Astronomy Evolved

Stargazing has always inspired people to wonder what was out there in the night sky. Some thought the stars were past relatives or ghosts. Others thought they were Gods. One thing for sure was that no one knew for sure. From the beginning of time this has been the case. We have always wondered. Even in modern times where we know many things, we still wonder how modern astronomy evolved. As science and technology evolved, our understanding of astronomy has increased steadily though. Stargazing will forever be popular and rightly so. How modern astronomy evolved will forever be a journey to people.
