Color Vision: One of Nature's Wonders.
Evolution has dictated that we are visually orientated. The human brain and visual cortex are capable of processing huge amounts of visual data and can quickly and efficiently recognize and extract useful information from this data. In fact, studies have shown that we receive approximately 80% of our external information in visual form.
Generally speaking, however, most of us tend to take our visual capabilities for granted, especially when it comes to color vision... View Topics. The Speed of Light in Glass. There is no pink light. Where International Standard Units Come From, Part One: The Meter. Think of the most fussy science teacher you ever had.
The one who docked your grade if the sixth decimal place in your answer was rounded incorrectly. Now imagine work that even that teacher would hate for being too anal-retentive. That's the kind of work that goes into defining the meter, the second, and other international standard units of measure. Here's a look at some ridiculously precise standards and the role that elements have played in defining, redefining, and re-redefining them over the ages. There are seven base units in the international metric system, and over the past century, metrologists (people for whom measurement isn't the start of science—it is science) have gotten increasingly picky about defining these seven quantities.
