Here’s a good example from engineering. An aerospace engineer might want to graph the lift of a wing versus the size of the wing‚ and he wants to show everything from an insect wing all the way up to a jumbo jet. A fly’s wing is maybe 0.1 inch long‚ and a jumbo jet wing might be 1000 inches long (about 80 ft). It would be pretty tough to put more than one insect on that graph - if you scale the wing length axis to fit on a sheet of paper‚ all the points for insect wings would be jammed up against
