| 11. | Start with the Newtonian particle of mass constrained to a spherical surface of radius within a uniform gravitational field.
|
| 12. | By enforcing the boundary condition on the spherical surface, the expansion coefficients of the scattered field can be computed.
|
| 13. | When the paraxial approximation is valid, the optical surface can be treated as a spherical surface with the same radius.
|
| 14. | :: Why is it " false " that the dispute is about " the dimensionality of a spherical surface "?
|
| 15. | Could you please give me an expression that gives the angle subtended by points placed symmetrically on a spherical surface.
|
| 16. | Zero-offset data is important to a geophysicist because the migration operation is much simpler, and can be represented by spherical surfaces.
|
| 17. | :: But Feynman does not connect the solution y = f ( x ) with the approximation of the spherical surface.
|
| 18. | So the floors are not parallel planes but concentric spherical surfaces, say 20 feet apart ( hey, it's a monumental building ).
|
| 19. | Light hitting a real, instead of ideal, spherical surface has aberrations .-- talk ) 06 : 22, 8 December 2013 ( UTC)
|
| 20. | Self-portraits in reflective spherical surfaces can be found in Escher's early ink drawings and in his prints as late as the 1950s.
