An Introduction to Science

By Vinny Papay

Science is one of the main topics that we study as children and young adults when in school. It is a subject that is all around us everyday, just like Mathematics and English, making these three topics key subjects at school. Just like most school subjects and topics, there are many sub topics and categories that we have to learn about while studying it. This article will briefly outline all the science topics so that you can be more informed about studying science if you are new to the subject. Most people like science but some do not understand it. I hope you find this article useful.

There are three main types of core scientific subjects. These are Biology, Chemistry and Physics. Of course, there are many more topics, however everything to do with science and the study of anything science related falls under these three categories. When choosing to take this subject as a further field of study, most individuals pick one of these three as a main study and it tends to be the one that they think is more interesting, so this may help you make a decision if you are thinking of becoming a scientist.

Biology

Biology is a natural science and it is the study of life focuses on the growth, structure and evolution of living organisms and looks at how they are formed. The basic focuses of biology are cell structures, the study of genes, new species and evolution, organisms and how they maintain life in certain environments/living conditions and how living things transform and consume energy. Biology is studies using the following methods and sub topics and it involves biochemistry, molecular biology, physiology, ecology, evolutionary biology and the study of the environment. Charles Darwin (1809 - 1882), born in England was a famous biologist who was famous for publishing his theory of evolution. His interest in nature made him give up his study of medicine and concentrate on nature instead.

Chemistry

Chemistry involves the study of matter. It examines the behaviours, properties, and interactions of atoms and groups of atoms. When studying chemistry is heavily involves experimenting with different substances and is used in most other scientific subjects like physics, biology and geology. This sub topic of science has been around since the beginning of history, when it was known as alchemy. Chemistry involves the study of elements, matter and experimentation. Dimitri Mendeleev (1834 - 1907) was a Russian chemist who developed the periodic table of elements, and used it to predict the properties of other elements still to be discovered.

Physics

Physics involves the study of natural science and natural philosophy. It studies the nature of matter and motion through time and space and also looks at astronomy and examines how the universe behaves and how it was created or made. The concepts of study includes and branches into chemistry, biophysics, quantum physics and mathematics. When studying physics things such as gravity, energy, motion, heat, waves and maths are looked at, as well as electricity and magnetism. Well known physicists include Sir Isaac Newton (1642 - 1727) who was famous for his theories about gravity and motion, Steven Hawking born in 1942 (and still alive today) who studies black holes and his theory relativity and quantum mechanics. Albert Eisntens' (1879 - 1955) theory of general relativity changed the way we think about and our understanding of the universe and gravity.

Science is a very wide topic with lots to talk about. I hope that you found this article useful and interesting to read and it was informative. There are many other famous scientists that are not listed here above as I have only mentioned a few, but these individuals have definitely contributed to our understanding of the world.
