... source shows the bright and dark fringes clearly (without the colourful pattern). As a beam passes through the lens, light on the lower surface of the lens is partially reflected (shown a beam A in diagram 1) but also partially transmitted. The transmitted part is then partially reflected at the ... the wavelength of the Sodium lamp light, 589.3nm, and n is the ring number (1 for the first bright fringe after the centre). If the lens has curvature r0 then, Hence, [3] Substitution of [1] & [2] into [3] gives, for bright fringes [4] for dark fringes [5] where tn is the radius of the fring...

... Leibniz used integration as a sum. He was also happy to use 'infinitesimal' dx and dy where Newton used x' and y' which were finite velocities. Of course neither Leibniz nor Newton thought in terms of functions, however, but both always thought in terms of graphs. For Newton the calculus was geometrical while Leibniz took it towards analysis. Leibniz was very conscious that finding a good notation was ... of fundamental importance and thought a lot about it. Newton, on the other hand, wrote more for himself and, as a consequence, tended to use ... whatever notation he thought of on the ...
