Astronomy For Beginners: Guide to the Universe

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.

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.
