Problems
The human eye is easily fooled, and Hipparchus's scale has had problems. For example, the human eye is more sensitive to yellow/red light than to blue, and photographic film more to blue than to yellow/red, giving different values of visual magnitude and photographic magnitude. Furthermore, many people find it counter-intuitive that a high magnitude star is dimmer than a low magnitude star.

Famous quotes containing the word problems:
“If combat means living in a ditch, females have biological problems staying in a ditch for 30 days because they get infections.... Males are biologically driven to go out and hunt giraffes.”

“It is not impossible, of course, after such an administration as Roosevelt’s and after the change in method that I could not but adapt in view of my different way of looking at things, that questions should arise as to whether I should go back on the principles of the Roosevelt administration.... I have a government of limited power under a Constitution, and we have got to work out our problems on the basis of law. Now, if that is reactionary, then I am a reactionary.”
—William Howard Taft (1857–1930)
