Not being given everything encourages you to create... That was one of the first steps for me learning to invent things.

It is important for me to remember that time learning anything substantial, even if it's not my favourite topic, is time well used.

I think parents are probably really excited for their kids and want to give them everything. But there should be a limit on how much you give your kids. Because kids are quite creative, especially at a young age when they don't really know what rules are.

Sport is one way of keeping kids off their phones.

It stands to the everlasting credit of science that by acting on the human mind it has overcome man's insecurity before himself and before nature.

Pure science - this vision of the universe as 15 billion light years across - I am bedazzled and awed by it.

Science is the highest personification of the nation because that nation will remain the first which carries the furthest the works of thought and intelligence.

I'm in favour of the old roles being blurred. The old division at school where the boys did metalwork and woodwork and the girls did needlework and domestic science is awful, really - and I'm glad it's gone.
