Chalky, regarding your reference about religion to Frank on Cambridge United Mad
I recommend that you discover all that you can on the internet about Richard Dawkins. He is probably the word's best known evolutionary biologist and he knows plenty about all the other sciences.
He is resolutely a non-believer in any religion.
He has written many best-selling books about the sciences and his non-religious beliefs.
He married a former Doctor Who companion, actress Lalla Ward, who he met at a party for the 40th birthday of Douglas Adams, who was the show runner of Doctor Who for a couple of years. Dawkins himself briefly appeared in Doctor Who (the modern version) as himself offering some science advice on a television program about a strange phenomenon.
