![]() ![]() ![]() ![]() It can’t be that difficult to figure out if Aristotle proved the round Earth more than 2,000 years ago with few scientific instruments. Have you proven for yourself that the Flat-Earthers are wrong, or have you simply believed the pictures and professionals?įortunately, there are multiple easy tests you can perform at your home to prove that the Earth is, indeed, round. Many of the Flat-Earther’s convictions come from how flat the Earth seems from our perspective. Would you believe in the round Earth then? Imagine we didn’t have those pictures from space. Maybe the existence of Flat-Earthers is a good reason to think critically about astronomy yourself, to actually understand why the Earth is round. It seems unlikely that anything will convince these believers of a different world-view. It has been scientific consensus for hundreds of years that the Earth is a near-perfect sphere.īewildering as it may be, some people just refuse to believe the mountains of evidence proving a spherical Earth. Have you ever proved that the Earth isn’t flat? While Flat-Earthers are one of the more out-there conspiracy groups, it’s fun to disprove them with simple tests in your backyard. ![]()

![]() ![]() If you go up a perfect fifth (clockwise in the circle), you get the key that has one more sharp or one less flat if you go down a perfect fifth (counterclockwise), you get the key that has one more flat or one less sharp. The circle of fifths gets its name from the fact that as you go from one section of the circle to the next, you are going up or down by an interval of a perfect fifth. The keys that are most distant from C major, with six sharps or six flats, are on the opposite side of the circle. The next most closely related keys to C major would be G major (or E minor), with one sharp, and F major (or D minor), with only one flat. This puts them in the same "slice" of the circle. ![]() So the most closely related key to C major, for example, is A minor, since they have the same key signature (no sharps and no flats). What makes two keys "closely related" is having similar key signatures. Keys are not considered closely related to each other if they are near each other in the chromatic scale (or on a keyboard). In theory, one could continue around the circle adding flats or sharps (so that B major is also C flat major, with seven flats, E major is also F flat major, with 6 flats and a double flat, and so on), but in practice such key signatures are very rare. The major key for each key signature is shown as a capital letter the minor key as a small letter. ![]() |
