"Imaginary" numbers don't fit anywhere on that line. They have their own line - think of it as being at right angles to the traditional number line, and intersecting it. Just as you can't say whether a point at (1,1) on a grid is "bigger" than a point at (-1,1), you can't say that sqrt of -1 is "bigger" than plain old -1; it's just different. In fact, depicting complex numbers - which are part real and and part imaginary - as points on a 2-dimensional grid was one of the key breakthroughs in the field.Dave BrooksThu, 22 Feb 2007 01:34:42 -0000http://granitegeek.org/2007/02/21/the-drawback-of-popularizing-science-and-how-come-some-folks-are-flummoxed-by-math/#comment-2109622I find the subject of 'imaginary numbers' fascinating, and I'd like more explanation, tho I admit formulas would leave me flummoxed (to borrow your most excellent choice of words). Positive and negative numbers form a sort of linear progression, right? So-called imaginary numbers must not fit into that line anywhere, or they would be regular numbers, so where are they, in relation to it? And do they have anything to do with quantum uncertainty? It's all too much for my bitty liberal arts brain, but, as I said, fascinating.andrewWed, 21 Feb 2007 10:23:22 -0000http://granitegeek.org/2007/02/21/the-drawback-of-popularizing-science-and-how-come-some-folks-are-flummoxed-by-math/#comment-2109621I just found your blog and find it very interesting. My husband and I have a podcast where we talk about history with respect to architecture and engineering called aspire at <a href="http://szilverwolf.com" rel="nofollow">szilverwolf.com</a>. Please check it out if you would like. I am finding that there are only very select groups of people interested in our subject choice. I was not interested in history in engineering school either. I think that had to do with a busy schedule though. The "Carl Sagan Syndrome," mentioned above is also very upsetting. There has to be someway to inspire our students into science! I will have to check out this book. Well I love the article!SuzanneWed, 21 Feb 2007 02:17:18 -0000
