banktoturn,
Try this for a more scientific explanation:

Everything that I have been discussing is all there. You do NOT need tip vortices for lift, they are a result of having to engineer airplanes to work in the real world. Please read.
Ken,
1) That write-up is not 'more scientific'.
2) It didn't say that tip vortices are unnecessary for lift.
3) If something is necessary in the real world, it is necessary.
