170 & 182 Dennison Building
Speaker: Professor Myron Campbell (U-M Physics)The unification of electricity and magnetism brought with it two surprises. The first was the prediction of electromagnetic waves, which lead to both new understandings and new inventions. The second was the theory of special relativity, although it would be another 25 years before this was understood. Professor Campbell will demonstrate the properties of electromagnetic waves with a model of Hertz's generator as well as modern equipment. He will also demonstrate the wave nature of light. He will explain one of the effects of special relative time dilation by using light. Finally, Professor Campbell will show us how the historical development of the theory of electricity and magnetism has parallels to our current efforts to unify gravity and quantum mechanics.
All talks are free and refreshments will be served. Visitor parking for the seminars (Central Campus) is across the street from the Dennison Building in the U-M Church Street structure. There is a $2.00 parking charge implemented by U-M Parking Services.
