Faraday... wasnt a mathematician and so he relied on other people to d — Christopher Budd (mathematician)

"Faraday... wasnt a mathematician and so he relied on other people to do his math... and Maxwell... took Faradays experimentally derived results, and... turned them into mathematical equations.{{center|1=\nabla \times \mathbf{E} = -\frac{\partial \mathbf{B}}{\partial t} - \mathbf{M}, \quad \nabla \times \mathbf{H} = -\frac{\partial \mathbf{D}}{\partial t} + \mathbf{J}, \nabla \cdot \mathbf{D} = \rho, \quad \nabla \cdot \mathbf{B} = 0.}} ...and these are called Maxwells equations, and if you go to Edinburgh and you see his statue, on the base of the statue you will see these equations... which link electricity \mathbf{E} with \mathbf{B} and \mathbf{M}, which are magnetism, and \mathbf{J} is current, and \rho is charge, and these are... vector operations, and thats a derivative. ...Maxwell ...took those equations and looked for solutions, and... discovered that there were solutions... where you have an electric wave and a magnetic wave... paired... and traveling together, and he worked out the speed of those waves... exactly the speed of light. ...[I]n those equations he unified electricity, magnetism and optics all in one setup."

"But then he did something which mathematicians can do... [i.e.,] what-if experiments. You can say... what if these equations have other solutions, and he found... waves with the same speed as light, but a different and than light... and we now call them radio waves. ...Maxwell discovered radio by pure mathematics alone. It was later... that... Hertz found them experimentally, and... later... Marconi and others took the theory and turned it into practical means of communication."

"Who was the most famous female mathematician? ...Emmy Noether, [was an] excellent... fantastic mathematician, but if I went into the street, who would know Emmy Noether? ...Even more famous than Marie Curie. Films have been made about this woman. Ada Lovelace... famous, but not as famous as this one. Ive seen films, books have been written about her. Hugely famous, most children would know her name. Im going to put her picture up and its going to surprise you. ...Florence Nightingales an incredibly famous woman because... she basically founded modern nursing. ...The story ...she was sent to Crimea and... set up hospitals... which saved huge number of lives, and when she went back to England she developed modern nursing and her practice... are used all over the world, and everyone thinks shes a nurse, but... she was a . She was one of the first members of the and was a really good statistician... [T]he way she cured people wasnt so much through medical care. Its through the... more modern approach, which was to try to work out what was causing people to be ill. ...[S]he gathered loads and loads of data on this and... produced graphs of this data... essentially to convey what she was doing to politicians, because politicians then and sadly now, dont know what numbers are... [S]o she did this through graphical information and she developed... rose diagrams which are very like pie charts... [S]o she not only developed ... she also developed graphical presentation of data, which is universal, and shes incredibly famous, but noone knows she was a mathematician. ...The Royal Statistical Society ...building is called the Nightingale building, after her."
