1904 and earnest rutherford and dating
His conclusions led him to propose the Rutherford model of the atom.When asked for your age, it's likely you won't slip (with the exception of a recent birthday mistake).But for the sprawling sphere we call home, age is a much trickier matter.This week, Cherry Lewis of the University of Bristol presented a talk about the history of dating the Earth as part of the BA Festival of Science in York, England.New Zealand-English physicist who laid the groundwork for the development of nuclear physics. Birks, Rutherford at Manchester (1962), 108, without citation.He identified alpha, beta and gamma emissions during radioactive decay, and devised the alpha-particle scattering experiment that led to the discovery of the atomic nucleus. Webmaster has not been able to find any earlier example of the quote in print. I think a strong claim can be made that the process of scientific discovery may be regarded as a form of art.By the end of the 19th century, many geologists still believed the age of the Earth to be a few thousand years old, as indicated by the Bible, while others considered it to be around 100 million years old, in line with calculations made by Lord Kelvin, the most prestigious physicist of his day.
To my relief, Kelvin fell fast asleep, but as I came to the important point, I saw the old bird sit up, open an eye and cock a baleful glance at me! A fine example is the famous Kinetic Theory of Maxwell. The theory of relativity by Einstein, quite apart from any question of its validity, cannot but be regarded as a magnificent work of art. ' at the Royal Academy of the Arts in 1932.) Quoted in Lawrence Badash, 'Ernest Rutherford and Theoretical Physics,' in Robert Kargon and Peter Achinstein (eds.) Kelvin's Baltimore Lectures and Modern Theoretical Physics: Historical and Philosophical Perspectives (1987), 352.It was not until the 1950s that the age of the Universe was finally revised and put safely beyond the age of the Earth, which had at last reached its true age of 4.56 billion years.Physicists suddenly gained a new respect for geologists!Dating of the age of the Earth was one of the most important developments in geology, because it ultimately led us to understand how continents moved around the globe.Dr Cherry Lewis from the University of Bristol will talk about the history of dating the age of the Earth at the BA Festival of Science in York on Thursday 13 September.
