There is nothing new to be discovered in physics now. All that remains is more and more precise measurement. (Lord Kelvin, 1900) Address to the British Association for the Advancement of Science, 1900 ©Hunterian Museum and Art Gallery, University of Glasgow. Licensor
All that remains to do in physics is to fill in the sixth decimal place (Albert Michelson, 1894)
What did we know about science, the world and the universe in 1900?
What has been discovered in physics since 1900?
Fortunately… ‘No matter how we may single out a complex from nature...its theoretical treatment will never prove to be ultimately conclusive... I believe that this process of deepening of theory has no limits.’ (Albert Einstein, 1917)
Lord Kelvin did have a little idea… … he mentioned two ‘clouds’ on the horizon of physics: 1) blackbody radiation 2) the Michelson–Morley experiment.

What are the most important questions that physics is asking?

Three fundamental questions drive the research at CERN Where do we come from? What are we made of? What is the future of the universe?
What do you need to be successful in Higher Physics? What do you need to be successful ?
Alvaro de Rujula, theoretical physicist, CERN It pays not to know very much (no preconceived ideas!) Challenge what you do know (let go of your misconceptions) Be young (most big discoveries are made by scientists early in their careers)
