| Quotations for Today | |
| "The violent reaction on the recent development of modern physics can only be understood when one realises that here the foundations of physics have started moving; and that this motion has caused the feeling that the ground would be cut from science." - Werner Heisenberg (born 5 Dec 1901) "Any device in science is a window on to nature, and each new window contributes to the breadth of our view." - Cecil Frank Powell, British Nobel prize-winning physicist (born 5 Dec 1903) "If you want to be a physicist, you must do three things - first, study mathematics, second, study more mathematics, and third, do the same." - Arnold Sommerfeld, German physicist (born 5 Dec 1868) | |

| Cecil Frank Powell, born 5 Dec 1903, was a British physicist who was awarded the Nobel Prize for Physics for 1950 for his development of the photographic method of studying nuclear processes. This resulted in the discovery of the heavy subatomic particle originally theorized by Yukawa Hideki. Which sub-atomic particle predicted by Hideki was discovered with Powell's photographic method? | |
| Arnold Sommerfeld, born 5 Dec 1868, was a German physicist whose first work was on the theory of the gyroscope, but his significant work was a major contribution to the development of quantum theory. Using quantum theory, what phenomenon did he relate to the Bohr atomic model? | |

| Sir Robert Alexander Watson-Watt (1892-1973) was a Scottish physicist whose early work (from 1917) was in the Meteorological Office, designing devices to locate thunderstorms, and investigating the ionosphere (a term he invented in 1926). His significant work in another field led to the development which played a vital role in the defence of Britain against German air raids in 1940. What was this vital development from his work? | |
