Unattributed Quote That Leads to Historical Misrepresentation

Webmaster has searched for a primary print source without success. Walter Isaacson likewise found no direct evidence, as he reports in Einstein (2007), 575. However, these sentences are re-quoted in a variety of books and other sources (often citing them as a remark reportedly made by Kelvin in an Address at the British Association for the Advancement of Science in 1900). Although the quote appears noteworthy, it is not included in the major biographical work, the two volumes by Silvanus P. Thomson, The Life of Lord Kelvin (1976). The quote is included here so that this caveat should be read with it.

"There is nothing new to be discovered in physics now. All that remains is more and more precise measurement." is a quote often attributed to Baron William Thomson Kelvin, and I have personally heard from others that there was a time when scientists thought Physics had reached the end of exploring before the discovery of quantum physics, but TodayInSci cannot find the source of this quote.
