The paper gives an exact formula for determining the intensity of an optical field at the center of a spherical particle of arbitrary radius obtained by evaluating an indeterminate form of the 0/0 type of Mie theory for the electric‐field components at the center of the sphere. This formula...

The meaning of CENTER is the point around which a circle or sphere is described; broadly : a point that is related to a geometrical figure in such a way that for any point on the figure there is another point on the figure such that a straight line joini

the sphere must be thought of as seen from its centre. The field of vision or of thought is like a sphere whose radii proceed from one’s self in every direction, and extend out into space, opening up boundless vistas all around. It is the symbolical circle of Pascal and the Kabalists...

always coincide, however. For example, theMoon’scentre of mass is very close to its geometric centre (it is not exact because the Moon is not a perfect uniform sphere), but its centre of gravity is slightly displaced towardEarthbecause of the stronger gravitationalforceon theMoon’snear side...
