The definition of a limit continues on in our learning limits and how they are applied. Specifically we are going to look at some proofs in this section. With a precise definition we can now prove many limit properties.

The Moon has been up there in the sky looking back at us for as long as there has been a sky. Where did it come from? Why do we see only one side continually? The Moon is mysterious and I think we can all agree on that. There are many unanswered questions and the fact remains that many of them we just don't know. In this article I will try to answer some of these more common questions in ways that make sense.

Beginning calculus problems with limits of a function are a common teaching technique for young students that are just starting their journey in Calculus. Limits problems will help you understand how they work and what is going on when you encounter a function. Repetition is key here to get your brain used to thinking about what a function or a graph means. I include several examples below in order for you to practice and grasp the concepts.

In this article Biology For Beginners: Themes of Life, I talk about the life that is fundamental to our world. Its characteristics and depth are amazing and worth our time to understand as well as possible. Since life ties into all things it only makes sense to further our understanding. Read more if you are curious.

The solar system is very interesting. There are countless objects wandering around out there. We have learned much from even the smallest things like dust in space. The Solar System is a very complicated and busy place. To learn we measure everything we can and then compare constantly. That is the fun of it to me. I love looking at data and seeing how objects are different and all the ways in which they are the same.

How telescopes are used in modern Astronomy is changing every decade. We used to only use them to see objects with normal light. Now we can leverage our technology gains to see different wavelengths of light in the universe. This has opened up our studies with a lot more data than we previously had. This article talks about the different fields and categories of astronomy and what they mean.

Spectroscopy is one of the core techniques for understanding distant stars. Thanks to the fundamentals of light and how it behaves, we can collect the radiation from objects and infer many details from them.

If you love Astronomy, then looking at the sky is a regular task for you. Today, I would like to talk about why we see what we do. 

When I was a kid growing up in Kentucky I always loved going out at night and seeing the sky. My home was very unpopulated and so had very little light pollution. The nearest town of 3 thousand people was about 15 miles away. So it was an incredible place to dream about what may lie among the stars. That was the start of my love for science, astronomy, and physics.

I have carried this with me my whole life and always wanting to learn more because I loved it. I have always wanted to write about it as a result. This is a short guide to the universe and includes the beginning topics. From here most of the advanced concepts come from these ideas and are developed more fully.

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.

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.

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.
