The Errors of Professor KellandSlide7

William Thomson BATAIAP:The Cambridge Years (1841-45)

‘I am most

desperately disappointed…I am not consoled to learn that so and so, and so and so, stood second. I expected him to stand first, and the only thing that reconciles me is that

we all needed this mortification.’Aunt Agnes, on hearing that William was not senior wranglerSlide8

Telegraphy

‘It is the most wonderful thing...Messages were sent out to Manchester,

Edinburgh &c., and answers were received in a few seconds- truly marvellous!’ Queen VictoriaSlide11

Transatlantic telegraphy 1856-1866

Shipping the cable on board the Great Eastern (1865)Slide12

Transatlantic telegraphy, Thomson and Fourier

Telegraph equation (Heaviside 1876)Telegraph equation (Thomson 1855)Slide13

Tides, Thomson and FourierSlide14

Tides, Thomson and Fourier

we know H(t) – from the tide gauge

we know the ‘

ω’s - from astronomical datawe can calculate the As and Bs (port dependent numbers) by using integration (i.e. working out the areas under certain curves)Slide15

Tides, Thomson and FourierSlide16

Some bigger things that William did...

The first university physics labAn enthusiast for the creation of new universities The systematisation of thermodynamicsThe centrality of energy in physicsSlide17

T&T’

‘William Thomson and Peter Guthrie

Tait’sTreatise on Natural Philosophy of 1867was a quite self-conscious effort to replace

Newton’s Principia as the foundational textof a new kind of natural philosophy.’Iwan Rhys Morus, When Physics Became King,Chicago Univ. Press (2005)One object which we have constantly kept in view is the grand principle of Conservation of Energy. According to modern experimental results, especially those of JOULE, Energy is as real and as indestructible as Matter. - From the PrefaceSlide18
