Well, the equation for the bending of light is
alpha = 2 * G * M / (c^2 * R)
R in this case is the distance of closest approach of the light, measured from the center of mass. G is the gravitational constant, c is the speed of light, and M is the mass of the object. Of course, this only holds if the object bending the light is a sphere, but approx. the book is a sphere. It will not affect the result that much:)
(g / c^2) is a constant = approx. 10^-27 m/kg
So the only thing we need to measure is the ratio of the mass to the radius...assume thats about.5 kg/m... that makes the angle the light is bent to be approx. 10^-27 radiens, which is really, really small.
To compare, the Sun has a mass to radius ratio of about 2.86x10^21 kg/m and thus bends light by about 4.2x10^-6 radiens, which is measerable. For the earth, m/r equals approx. 10^18 kg/m
Kazuo Ishiguro : The remains of the day. His writing is so precise, so exquisite, so flawless, I don't believe there has been an English-language novelist to compare. I actually prefer his The Unconsoled, but I don't think it has the same aura of classicism.
I agree. Last year I took a Modern British Literature class (we read Lord of the Flies, Heart of Darkness, Passage to India,...) and we also read Remains of the Day. It was one of the better books we read in that class. When a book is starting to be taught in English 267, it will probably stand the test of time!
