Zitat des Tages von Robert Woodrow Wilson:
Radio Astronomy has added greatly to our understanding of the structure and dynamics of the universe. The cosmic microwave background radiation, considered a relic of the explosion at the beginning of the universe some 18 billion years ago, is one of the most powerful aids in determining these features of the universe.
I consider myself so lucky.
An antenna collects radiation from a desired direction incident upon an area, called its collecting area, and focuses it on a receiver. An antenna is normally designed to maximize its response in the direction in which it is pointed and minimize its response in other directions.
My high school career was undistinguished except for math and science. However, having barely been admitted to Rice University, I found that I enjoyed the courses and the elation of success and graduated with honors in physics. I did a senior thesis with C.F. Squire, building a regulator for a magnet for use in low-temperature physics.
A radiometer is a device for measuring the intensity of radiation. A microwave radiometer consists of a filter to select a desired band of frequencies followed by a detector which produces an output voltage proportional to its input power.
Following Rice, I went to Caltech for a Ph.D in physics, without any strong idea of what I wanted to do for a thesis topic.
