Subject: Physics (Fluid Mechanics)
How does fluid dynamics differ from solid mechanics and physics? Where do the theories and equations come from?
Fluid dynamics is an evergrowing field. It is based on some basic theories from physics. Conservation of mass, and conservation of energy. These are known as the first law of thermodynamics. Although these may sound easy after coming through physics, fluid dynamics takes a different view on how to analyze a problem. To solve the conservation equations, in a field of ever moving particles, you must learn how to change the reference frame. Physics uses a Lagrangian frame and fluid mechanics uses a Eulerian frame. This makes the equation much more complicated and causes many basic theories to become much more difficult than solid mechanics, or physics counterparts. Although many of the theories may sound familiar, the fluid dynamics counterpart is almost always more difficult. To try and learn fluid dynamics, you must learn how to reimagine even the most basic physics concepts.
Subject: Basic Chemistry
What is covered in the basics of chemistry? Where is basic chemistry used? Why should I learn it?
The basics of chemistry covers many ideas in chemistry at a low level. It teaches how to name compounds, atomic structures, how to read the periodic table, stoichiometry (chemical balancing), and many more ideas. If you are doing anything in chemistry, biology, physics, and most engineering, chemistry does come up again in many different ways. The basics of chemistry are important in understand strength of materials ideas, they relate closely with all of biology, share very important ideas with thermodynamics, fluid dynamics, hydrodynamics, and many other courses. Basic chemistry is an important building block for every STEM major and allows for a greater understanding of many everyday processes and ideas.
What is physics and why should I study it?
Physics is the branch of science that focuses on energy and matter. It is thought of as the 'purest' science and relates closely with many calculous ideas and models. Physics can teach you many things, including how the world works around you. It teaches the ability to analytically study and analyze numbers, properties, and demonstrates the application of many theories. Physics is the building block for many different branches of study. These include engineering, chemistry, astrophysics, thermodynamics, fluid dynamics, and many other subjects.
