Henry Drummond: Language is a poor enough means of communication. I think we should use all the words we've got. Besides, there are damned few words that anybody understands!
Inherit the Wind (1960 film), Jerome Lawrence and Robert Edwin Lee
The brightness of the Sun varies on all time scales and wavelengths. An EU-funded initiative is gathering scattered observations from over 25 instruments to accurately represent how solar irradiance variability influences Earth's climate.
