Scientific Technology:Brian Greene On String Theory
In the year 1919, a virtually unknown German mathematician named Theodor Kaluza suggested a very bold, and in some ways, a very bizarre idea. He proposed that our universe might actually have more than the three dimensions that we are all aware of. This idea has had a major impact on physics in the last century and continues to inform a lot of cutting-edge research.
