But why are such terrific efforts made just to find new particles?’ asked Mr Tompkins.

‘Well, this is science,’ replied the professor, ‘the attempt of the human mind to understand everything around us, be it giant stellar
galaxies, microscopic bacteria, or these elementary particles. It is interesting and exciting and that is why we are doing it.’

‘But doesn’t the development of science serve practical purposes by improving the comfort and well being of people?’

‘Of course it does, but this is only a secondary purpose. Do you think that the main purpose of music is to teach buglers to waken soldiers in the morning, to call them for meals, or to order them to go into battle? They say “curiosity kills the cat”; I say “Curiosity makes a scientist”.’

And with these words the professor wished Mr Tompkins a good night.
