 Spectroscopy Atomic Clocks: An Application of Spectroscopy
1/1/2007: 2,051 words, approx. 7 pagesTime is one of the seven fundamental quantities in nature. I made a case in the last installment of this column (1) that mechanical devices for measuring time — clocks — might be considered the world's first scientific instruments. Clocks are ubiquitous because the measurement... summary from source:
Spectroscopy The Original Scientific Instrument
12/1/2006: 1,415 words, approx. 5 pagesAfter due consideration in my copious free time, I have reached the conclusion that the world's original scientific instrument was the clock. Yes, I know that people have used mirrors since antiquity, and humanity used their eyes to study the world around them (and used...
