Physics used to be much simpler.<\/p>\n
When my parents were at school in the 1930s, they were taught that there is nothing smaller than an atom. When I was at school in the 1960s and studying Physics ‘A’ Level, we were taught that there were three sub-atomic particles: the neutron, the proton and the electron. In fact, scientists already knew that there were more than three but our teacher clearly did not want to confuse us.<\/p>\n
Now the Standard Model<\/a> of particle physics – sometimes known as the theory of almost everything – involves many dozens of sub-atomic particles and today we have the news<\/a> of the discovery of yet another: the\u00a0chi_b(3P). How exciting is that?<\/p>\n","protected":false},"excerpt":{"rendered":" Physics used to be much simpler.
