This work allowed others the mechanical understanding of the universe to develop many of the advanced electronic inventions of the 20th century.

of the discoveries made in physics during the early 20th century. The objective of this course is to provide an understanding of the physical concepts and theories of modern physics. These concepts will aim to make you understand relativity‚ quantum mechanics‚ particle and nuclear physics. Most of these topics are now known as “Non-Classical Physics”. A few brilliant scientists were able to see and put together new theories that changed our understanding of the universe forever. This is not an

1. Atomic and Molecular Structure a. Students know how to relate the position of an element in the periodic table to its atomic number and atomic mass. The Periodic Table organizes elements by their atomic number - from hydrogen (1) to whatever is the highest one currently known (>105). It is arranged so that similiar members fall in a list such as Chlorine Bromine etc.. The average atomic weight is usually shown with each element‚ but due to isotopes (caused buy nuclear varations)

properties can be derived from first principles without recourse to particle or wave mechanics. The approach‚ which is referred to as guided-wave mechanics‚ is based on the kinematics of photon propagation rather than field modes‚ the latter tending to obscure the underlying mechanics. As a consequence‚ concepts that appear as postulates in traditional relativistic quantum mechanics appear in guided-wave mechanics as derived quantities with physically intuitive‚ albeit novel‚ interpretations. This

things in the universe‚ one must first realize the two pillars of modern physics. First is Einstein’s general relativity and then the concept of quantum mechanics. Relativity provides a framework for understanding the universe at a large scale‚ we are talking about stars‚ galaxies and even larger objects(galaxy clusters‚ black holes even). Quantum mechanics does the opposite‚ provides a framework for the smallest of scales: such as molecules‚ atoms‚

It was explained mathematically by Einstein‚ utilising work in quantum mechanics‚ and was developed by people like Max Planck. The photoelectric effect was not just an immediate discovery with a definite drawn conclusion. It involved many years of research‚ experimentation and debating

Today I will introduce a famous and outstanding scientist to you. A brief history of Stephen Hawking. The main contents include four aspects Stephen William Hawking is an English theoretical physicist and cosmologist‚ whose scientific books and public appearances have made him an academic celebrity. Stephen William Hawking was born on 8 January 1942 (300 years after the death of Galileo) in Oxford‚ England. His parents’ house was in north London‚ but during the Second World War Oxford was considered

Sir Isaac Newton who produced the Newtonian mechanics influenced Einstein; this led to Einstein’s development of the special theory of relativity. This theory was later expanded to gravitational fields. Einstein is best known for his mass-energy equivalence formula E = mc2 (1)‚ this has been dubbed

One argument against continuing research on the atom is that the cost continues to increase at an alarming rate‚ and the benefits seem to be declining. Wheras quantum chemistry experiments as early as 80 years ago were very cheap and yielded considerable practical results‚ now very few if any practical results are emerging‚ but the costs of experiments continues to increase. For example‚ the Large Hadron Collider(LHC)
