Measurement, uncertainty and lasers /

The measurement of values is fundamental in science and technology. Not only does this book include the importance of uncertainty, accuracy and precision of measurement, it also explains how laser technology has helped improve measurement and redefine standards. Masatoshi introduces the concept of t...
