Are dogs colorblind? Yes, although not in the way most people think. Color perception Dogs compared with Humans ‘Colorblind’ is a somewhat subjective term biased toward trichromatic vision–the kind of sight most human beings enjoy. But our electromagnetic range is not the pinnacle of color perception. From a bird’s perspective, it is humans that are colorblind–we could never perceive the vast complexity of hues available to denizens of the air.

Intelligence is a fascinating, though complex subject, and it’s one that is difficult to study for that reason. Researchers have developed IQ tests to try and create some kind of objective, quantitative measure of human intelligence. Despite their many flaws, IQ tests present a clear quantitative bell curve with 95% of their participants scoring within a range of 70 to 130. There are a couple different classifications of IQ scores. One common classification is Wechsler’s, which ranks 90-109 as the true average.

What Are The Colors of the Rainbow? When you look at a rainbow in the sky, all the colors can seem to blend together, but there are seven distinct hues that form the arc. In order, these are red, orange, yellow, green blue, indigo, and violet (in grade school, you may recall these colors in the acronym ROY G BIV). These colors combine to form all the other colors which we can see with our eyes, though they only form a small part of the electromagnetic spectrum.

**_The Titanic - which sank April 15, 1912 - is remembered as the worst maritime accident in history, not only because the sinking of the ship itself was tragic, but because the hubris of the builders who called the ship “unsinkable” - led them to include only enough lifeboats to salvage about half the passengers._** “Arrival of the ship of sorrow”, published in the Boston Globe May 4, 1912.

Time zones are a universal standard used to mark the hours of the day in different locations. The reason time zones are necessary is to correct for the fact that, geologically speaking, people in different locations experience the hour at different “times” of the day. The Royal Observatory in Greenwich If there were no time zones, "noon," for instance—when the sun is at its highest point in the sky—would occur at 5:05 in one place and 12:36 in another, defeating the purpose of having standard time across regions.

Humans have long been fascinated by the concept of immortality. Our most enduring myths recount the search for fountains, elixirs, holy grails, and other elusive means thought to confer of the gift of eternal life. It has always been the stuff of legend.
