Voyage Through Time: Walks of Life to the Nobel Prize

When I was a child, I thought of my Delta town as the center of the universe, but now I realize how little I know about the universe. As a child, I thought I was immortal, but now I recognize how limited a time we all have. As a child, success meant scoring A on every exam, but now I take it to mean good health, close family and friends, achieve- ments in my work, and helping others.

Interestingly, this was the only incident of blatant prejudice that I can remember. But I am aware that such opinions exist in human beings, and it's not a question of being Egyptian or being an Arab or being a Muslim.

The prefix milli comes from Latin (and French for “thousandth”), micro and nano from Greek (for “small” and “dwarf respectively), and pico from Spanish (for “small”). Femto is Scandinavian, the root of the word for “fifteen” (femten)—nuclear physicists call a femtometer, the unit for the dimensions of atomic nuclei, a fermi. Attosecond, the next smaller unit, 10-18 second, uses a prefix also derived from Scandinavian, from the word for “eighteen.
