The quantity derived in the lecture, from fundamental constants, had the correct units. Sorry. On 07/22/2015 08:28 PM, Tom Karzes wrote: [Hide Quoted Text] There seems to be a problem of units here. Distance times distance gives area, not distance. In this example, a simple unit change will allow you to produce any result you wish, since "units" and "units^2" don't scale the same. There would have to be a divide by another distance, with units, for this to work. Tom
