We simplify the ...We live in a 2.5 dimension world. We simplify the matter of a half a dimension by rounding up. Given a metric each new dimension would add value to the distance from the beginning of the measurement to the end. Once no new distance is added, the dimension has converged. It need not be a whole dimension. <br /><br />Changing the metric, or the sensor, the number of dimensions would change. It seems multinormal. <br /><br />I've never seen any mention of negative dimensions. DavidWLockehttp://www.blogger.com/profile/15166693219648673080noreply@blogger.com
