"There are no limits to what we can imagine using our biological structure."

"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 what we find, what we can create,

what we do with what we create, and, what we don't know or understand"!

Doc Brown April 2019

The top button navigation bar is repeated on every revision notes page. The Google search box below is dedicated to my site - very useful. This is a big site of >1500 science pages, so you need to explore it patiently and get to know what is useful and bookmark appropriately.
