It has become clear to most scientists that experiments requiring relly high intensities in narrow spectral regions
can only be done with lasers and not with conventional light sources.

Science and Profit
Faraday's discoveries in the field of electromagnetism attracted much attention but
their importance was little understood. One day a member of parliament visited Faraday
and asked him to show some of his experiments. Faraday demonstrated the phenomenon
of induced currents (возбуждённый электрический ток).
"What's the use of it? " asked the visitor.
"Soon you will be able to tax it," was the scientist's answer.
The Gold From the Sun
The German physicist Kirchhoff (1824–1887) was delivering a lecture. He explained that the dark lines shown by
the spectroscope proved that the Sun contained gold. One of the listeners, a very rich man, said to Kirchhoff:
"What is the use of the gold if I never can get it from the Sun? "
Some time later the scientist was awarded a gold medal for his invention of the spectroscope analysis. Showing the
medal to the rich man he said:
"Look here, I got the gold from the Sun, nevertheless."
