It was 'Doc Brown's Chemistry', but I've branched into biology and physics!

The top button navigation bar is repeated on every revision notes page.

The GOOGLE SEARCH BOX BELOW, is also at the bottom of every page, AND, is dedicated to my site - very useful - I use it myself! It's a big site of over 1600 science pages (+ 2500 travel picture pages), therefore, you need to explore my website patiently - index below, and get to know what is useful to YOU and bookmark pages appropriately!  The whole of this science website is written by the 'one man band' of Dr W P Brown - retired chemistry-physics-general science teacher. All contents Dr Phil Brown 2000 onwards

There are no limits to what we can imagine using the biological structure and function of our brain. Our imagination is created by the laws of chemical reactions and quantum physics. Therefore, there are no limits to what science can achieve and help us understand. BUT, there will always be questions, both scientific and philosophical, about (a) what we find out, (b) what we can create, (c) what we do with what we create, and (d), what we don't know or understand.

Above are links to the main sections of Doc Brown's Chemistry's website, these in turn link to other sub-indexes from which I hope you will bookmark useful and relevant links for your science course. At the top and bottom of all revision notes pages of Doc Brown's Chemistry are more detailed sets of navigation bar buttons to which you should make yourself familiar. The Google search engine is dedicated to Doc Brown's Chemistry's website putting in 'anything of interest' and you can put in multiple words to get the best page match from Doc Brown's website.

"Doc Brown's Chemistry" is a website designed for UK science students studying GCSE Biology, GCSE/IGCSE Chemistry, GCSE Physics and Advanced Level Chemistry. My website covers the current science syllabus specifications from AQA, Edexcel and OCR examination boards. This science revision e-learning  website includes notes & quizzes for chemistry, but includes some biology and physics too AND lots of 'unofficial' revision summaries for ALL the current GCSE Sciences (links below). The new GCSE specifications starting in September 2016 will be eventually covered completely by Doc Brown's Chemistry plus biology and physics revision notes and specification summaries.
