Often great mysteries in life are in simple things. Like the scientific concept of 'mass'. You can define just about anything else in science clearly, but mass is different. The best even scientists can usually come up with is 'stuff'. I think there's something pretty mysterious and profound about why that is. It means this is one of the foundations of modern science, the taken for granted assumption that is then left out of all the theories and facts. So...what does it mean that science decided right from the start to not try to define what mass is?
