In the beginning

Genesis 1:1
In the beginning God created the heaven and the earth.

This is the first verse of the Bible, it is important to note that God is assumed to exist and he is designated as the first cause from which all affects come. Mentioned in this verse are the three main components of the universe space (the heaven), mater (the Earth), and time (the beginning).

In physics, relativity theory shows that space, matter (energy) and time are interrelated parts of the universe such they can not exist separately. It also shows that time is an integral property of the universe that can have a beginning. Furthermore the beginning of time must coincide with the beginning of space and matter and Genesis 1:1 is consistent with this.

The Work of Energy

Energy is the ability of a system to do work. Special Relativity shows that energy has mass and that the mass all matter is a result of energy, so that all substance is based on energy.

The 1st Law of Thermodynamics states that the energy in any interaction is conserved. The result is that is the total amount of energy in the universe is constant. It is also stated as energy can not be created or destroyed but it can change forms.

Below is a list of common types of energy
  1. Heat energy is the energy associated with the temperature of an object.
  2. Light energy is the energy associated with visible light.
  3. Electrical energy is the energy associated with an electric current.
  4. Chemical energy is the energy associated with the reactions involving molecules.
  5. Nuclear energy is the energy associated with reactions involving atomic nuclei.
  6. Kinetic energy is the energy associated with motion.
  7. Potential energy is the energy of a system based on its position or condition. Stored energy.
  8. Rest mass energy id tThe energy of an object that is not in motion. E= mc2
Energy is one of the three main parts of the Universe space, time and mass and relativity shows them to be inter-related. Space and time are so interrelated that they form a single entity. Furthermore mass warps space-time forming Gravity and the motion of mass contracts both space and time. 

In conclusion in common experience energy is what moves us and allows us to move thing. Physics has shown it to be a lot more. It is a fundamental part of the universe.

Introduction to Physics

Physics is the study of energy, and matter and  the ways they interact. Physics not just formulas you may not understand. While physic is scientifically expressed by formulas, it is more than those formulas. It can take the form of practical experience. 
Physics is even found in sports. Baseball is a prime example of physics in sports, specifically ballistics. Pool is another example of physics in sports specifically collision physics.

The two main founders of physics are Galileo Galilei and Isaac Newton. These two men are the main ones responsible for establishing modern physics, there were others involved but they were the most significant.

Physics is central to all other physical sciences including Astronomy, Biology, Chemistry, Cosmology and Geology.  Physics has shown us much about the structure of matter, the nature of Energy and the nature of space and time. Physics has the potential to shown us how the universe works and the nature of reality itself.

Concepts of Thermodynamics

Thermodynamics is the study in physics of the transfer of energy, the work it does and it’s affect on matter. Thermodynamics is dynamic and not kinetic so it is not concerned with the actual processes of energy movement. Thermodynamics deals with the results of the transfer of energy.
There are two main fields of Thermodynamics Classical Thermodynamics and Statistical Thermodynamics.

Thermodynamics was developed as a result of the study of steam engines and was based entirely on empirical measurement and it lead to the four laws of Thermodynamics. In their simplest forms Laws of Thermodynamics can be stated as follows:  

  • 1st Law of Thermodynamics: Energy can be neither created nor destroyed.
  • 2nd Law of Thermodynamics: The amount of unusable energy in a closed system increases.
  • 3rd Law of Thermodynamics: As the temperature of a substance approaches absolute zero it’s entropy of approaches zero.
  • 0th Law of Thermodynamics: Two objects in thermal equilibrium with a third object are also in equilibrium with each other. It is labeled the  0th Law instead of the 4th because it is more fundamental than the 1st law but it was discovered after the other three.
Statistical Thermodynamics works at microscopic as well as macroscopic level. It not only explains why the four laws of Thermodynamics work and it explains things that Classical Thermodynamics can not.

In conclusion the principles of Thermodynamics are the most well tested scientific principles known. They are also so general that they apply to everything in the universe including the universe itself. Thermodynamics is path independent so it often does not matter how one get from state “A” to state “B” which is why it applies to everything
