William Thompson (Baron Kelvin of Largs) “Lord Kelvin” Born June 26th 1824, Belfast, Ireland Graduated AT AGE 10 from The University of Glasgow!! His father was a professor Earned a BA from Cambridge Much later, became chair of “natural philosophy” (PHYSICS) at Glasgow. Died of the flu in 1907, in Scotland. Got title “Baron Kelvin of Largs” in 1892. Knighted by Queen Victoria for work on engines. “Kelvin” was taken from a creek that ran through the Cambridge University campus. Buried next to Sir Isaac Newton.

Lord Kelvin - William Thompson Just some of his many Achievements in Science & Technology Published 661 scientific papers! Held 70 patents! Held the record for the most academic letters behind his name! (?) Engineering Contributions: Supervised the laying of the first transatlantic cable. Basic Science Contributions: Helped Pierre & Marie Curie with the discovery of radium. Was the first to make a detailed analysis of ocean tides.

Evolution & Geologic time were impossible! Kelvin also had many achievements in Optics! First introduced the word chirality into science. First to associate an object’s color with it’s temperature. His ideas are still used today in color film & digital cameras. Calculated the age of the earth from its rate of cooling & decided that Evolution & Geologic time were impossible! This led to a public argument with Charles Darwin over evolution & the earth’s age. More on this some other time!

Some Interesting Kelvin Quotes “When you can measure what you are speaking about and express it in numbers, you know something about it; but when you cannot measure, when you cannot express it in numbers, your knowledge is of a meagre and unsatisfactory kind: it may be the beginning of knowledge, but you have scarcely, in your thoughts, advanced to the stage of science.”

All that remains is more precise measurement.” (1900)

Lord Kelvin (1824-1907) Kelvin’s Grave River Kelvin

In 1906, Kelvin proposed the “Plum Pudding Model” of the atom. Negative electrons were embedded into a positively charged spherical cloud. Equal quantities of (+) and (–) charge distributed uniformly in the atom. (+) is ~2000X more massive than (–) Spherical Cloud of Positive Charge Electrons Plum Pudding Named after a dessert, the plum pudding model portrays the atom as a big ball of positive charge containing small particles with negative charge.

“I trust you will avoid the gigantic mistake of alternating current.” More Interesting Kelvin Quotes “In science there is only physics; all the rest is stamp collecting.” “In physics, you don't have to go around making trouble for yourself - nature does it for you.” “Radio has no future. The X-ray is a hoax.” Writing to Niagara Falls Power Company: “I trust you will avoid the gigantic mistake of alternating current.” [The vector] “has never been of the slightest use to any creature.”

More Interesting Kelvin Quotes science than any man up to his time.” “Tesla has contributed more to electrical science than any man up to his time.” “Do not imagine that mathematics is hard and crabbed, & repulsive to common sense. It is merely the etherealization of common sense.” “Symmetrical equations are good in their place, but 'vector' is a useless survival, or offshoot from quaternions, and has never been of the slightest use to any creature.”

More Interesting Kelvin Quotes “ There cannot be a greater mistake than that of looking superciliously upon the practical applications of science. The life and soul of science is its practical application; and just as the great advances in mathematics have been made through the desire of discovering the solution of problems which were of a highly practical kind in mathematical science, so in physical science many of the greatest advances that have been made from the beginning of the world to the present time have been made in earnest desire to turn the knowledge of the properties of matter to some purpose useful to mankind.”
