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:
“I have a horror of people who speak about the beautiful. What is the beautiful? One must speak of problems in painting!”
—Pablo Picasso (1881–1973)
“More than a decade after our fellow citizens began bedding down on the sidewalks, their problems continue to seem so intractable that we have begun to do psychologically what government has been incapable of doing programmatically. We bring the numbers down—not by solving the problem, but by deciding it’s their own damn fault.”
—Anna Quindlen (b. 1952)
“...I have wanted to believe people could make their dreams come true ... that problems could be solved. However, this is a national illness. As Americans, we believe all problems can be solved, that all questions have answers.”
