| | When the Earth Moves - Magnetic Clues |
 | | Patrick M. S. Blackett (who received the 1948 Nobel Prize in physics for his work on nuclear physics and cosmic rays) at Imperial College, Stanley Keith Runcorn at Cambridge University, and Edward Bullard at the National Physical Laboratory in England were studying magnetism in rocks as part of their research into the nature of Earth's magnetic field. |
 | | Looking to see whether the rock's magnetism varied directionally, Blackett, Runcorn, Bullard, and their students found considerable evidence that throughout geological history rocks had somehow moved relative to the planet's magnetic poles. |
 | | By the mid-1950s, bolstered by paleomagnetic data gathered by Edward Irving at the Australian National University in Canberra, Blackett, Runcorn, and Bullard were convinced that Wegener had been right. |
