How does computer software plot magnetic field lines where the density of lines represent flux density? How does the software know which points to start plotting from in order to come out with a true representation?

I've finished a lab with Scanning Tunneling Microscopy in an upper level physics undergrad course, and now I have about 50 ".ezd" files to analyze. They were produced with the Nanosurf easyScan microscope, which I'm told is quite common in very basic applications. I'm looking for some...

Hi, What is the reason the most of the time, the software are much more expensive than the hardware components. If there is any important machine that is worth millions, then why its software is also too much expensive. Is it because of its complicated tasks or is there any other reason ? !

I've been reading (and a few people mentioned it as well) that electronics, software etc is moving to Asia. By moving I mean that you can hire a company there to do the job for you for less money because salaries there are lower. The reason I can think of is that electronics / software doesn't...
