While sometimes under the radar screen, borderline personality disorder (BPD) is a condition more common than schizophrenia or bipolar disorder and is estimated to affect 2 percent of the population.rullâs study, âChromosome 9: linkage for borderline personality disorderâ was recently published in Psychiatic Genetics and âHeritability of borderline personality disorder features is similar across three countriesâ was published in Psychological Medicine.
Taxicab geometry is a form of geometry, where the distance between two points A and B is not the length of the line segment AB as in the Euclidean geometry, but the sum of the absolute differences of their coordinates.
What appears on a map or flat surface as a straight line is not the shortest distance between two points. This is because the earth is not flat, but is a sphere. Thus the shortest distance between two points on a sphere is an arc rather than a straight and constant heading. This arc is called the great circle route.
