My young daughter was wearing a beat up old watch a friend had given her.
I asked her, "Does it tell the time?"
My daughter looked at me and said, "No, you have to look at it."
Thomas YoungBorn 13 Jun 1773; died 10 May 1829 at age 55. English physician, physicist and Egyptologist who reinforced the wave theory of light with his study of interference of light. As a medical student, he had discovered the how the shape of the eye's lens changes to focus. In 1801, he recognized the cause of astigmatism. Young demonstrated the wave nature of light, polarization of light, interference fringes, and explained the colours seen in thin films such as soap bubbles. He associated wavelength with colour of light, and the eye's perception of any colour as a mixture of red, blue and green. Young's modulus is named after his work with elasticity. He also worked measuring the size of molecules, liquid surface tension. He was also an Egyptologist who helped decipher the Rosetta Stone. |
