The scientific section of the website is essentially mine; that is, William's, and expresses my views and opinions alone. My interests range from the very small, Quantum Physics, to the very large, Cosmology. What I aim to do here is to give some basic introductions to the listed topics, try to dispel some misconceptions, and provide links for those interested in following up at more detailed levels. I plan to keep the information as up to date as possible; but, inevitably, I will miss some new ideas and theories as well as include some content that has been refuted. Hopefully, I will catch all these quickly.
Please feel free to let me have comments, suggestions and corrections, to any part of this section, but please keep it scientific. While I respect peoples religious, or any other, beliefs, here I have a zero tolerance policy towards any form of pseudo-science including creationism, intelligent design, quantum mysticism, and just about every other "ism". The Earth was NOT created 6,000 years ago, or 10,000 but 4.54 billion years ago ±1%. Also, humans were not created spontaneously, nor did they evolve from apes, monkeys, chimpanzees or wombats. The human species and chimpanzees had a common ancestor somewhere around 5 to 8 million years ago from which both species evolved separately. The next section on Pseudo-Science deals with these subjects.

Details of the terminology I use, links to various on-line sources of information plus some books that would be useful in gaining more detailed knowledge.
Brief Description
The history of the Hubble Space Telescope, some of its achievements and lots of wonderful astronomical pictures.
Early physics; pre relativity. Currently, we cover from the 16th century up to the very beginning of the 20th century.
Einstein's special and general theories of relativity. There is also a note about how relativity affects GPS positioning systems. Still think it is just a theory?
This section covers Quantum mechanics, both in its early manifestations and with later enhancements, Quantum electrodynamics, and Quantum chromodynamics.
The Standard Model of particle physics that covers the fundamental, indivisible particles and the forces acting on them. Essentially, this includes the various quarks, leptons and bosons.
This section covers the plethora of compound atomic particles constructed from the various quarks. Mainly hadrons and mesons, we also cover some of the more exotic, and hypothetical, particles like tetraquarks.
While special relativity and Quantum Physics have seen some successful merging in QED and QCD, this section looks at the ways physicists are trying to merge Quantum Physics with general relativity to produce a comprehensive theory of Quantum Gravity.
Or "What Banged in the Big Bang". A high level look at what occurred during the Big Bang, which remains the best theory to date for the origin of the universe. I discuss the period from the birth of the Universe up to the point when it is about a billion years old; approximately.
All about stars; how they are born, how they live and how they die, and what is left over after their death.
All about galaxies. Looks at how they form, the different types of galaxy, and how they evolve from one type to another. We also look at the affect of galaxy mergers, and some exotica like active galactic nucleii and lyman alpha blobs.
While galaxies are huge agglomerations of stars, they themselves form groupings; clusters, super-clusters, filaments and walls. There are also huge empty areas called voids and super-voids.
A highly speculative section that disusses dark matter, dark energy and topological defects.
Another highly speculative section that looks at what there is beyond the observable universe. Could there be multiple universes; a multiverse? What about the possibility of a dark flow causing non-random motion of galactic clusters?
Quick links to some of the very latest resarch that has been published.
A discussion of Gravity and the hypothetical graviton particle.
