Abstract: Kelvin (1824-1907) as the development of classical physics to the most brilliant era of one of the most influential physicists, its life research scope, in thermodynamics, electromagnetism, fluid mechanics, geophysics, mathematics and other aspects have outstanding contribution, known as Britains "Victorian King of Physics". Kelvin is also an outstanding engineer, not only applied for 70 patents, but also in the Atlantic cable of the century project from the design to the laying of the entire participation. Kelvin has a unique temperament of science and engineering technology in harmony, which is exactly what we are now pursuing the goal of talent training. 2024 coincides with the 200th anniversary of the birth of Kelvin, this paper reviews some of Kelvins research experience, to explore its body has a "dual identity" on the revelation of the present day as a commemoration of the Kelvin.

Key words: Kelvin, William Thomson, transatlantic cable project
