THE THREE QUOTES

Stephen Hawking

So long as the universe had a beginning, we could suppose it had a creator. But if the universe is really completely self-contained, having no boundary or edge, it would have neither beginning nor end: it would simply be. What place, then, for a creator?1

Charles Darwin

'As many more individuals of each species are born than can possibly survive; and as, consequently, there is a frequently recurring struggle for existence, it follows that any being, if it vary however slightly in any manner profitable to itself, under the complex and sometimes varying conditions of life, will have a better chance of surviving, and thus be naturally selected. From the strong principle of inheritance, any selected variety will tend to propagate its new and modified form.

Nicole Kuepper

“To pattern the cell we spray on something like nail polish and then inkjet print a kind of nail polish remover which lets us etch certain parts of the wafer. This creates a metallisation pattern so we can deposit aluminium on the back surface of the solar cell and create our metal contacts to both the P and N-type silicon simultaneously using a very cheap, low temperature pizza oven! And hey presto we’ve created a simple, low-cost solar cell without having to use expensive high tech equipment or high temperature processes!”3
