Math in the News: Christmas gifts for math geeks 
Okay,
this isn't news, but just some helpful advice on what to get that math
geek on your Christmas list. Anyone would appreciate the mug shown
here, especially since it includes the name of your favorite fortnighly
mathematical newsletter. Amazon
has (as usual) too many math geeky gifts from which to choose on its
website. Choices include numerous mugs, tshirts and a set of "the
proof is in the pudding bowls." Esty has a site devoted to gifts for math lovers that includes quadratic formula cufflinks, mathlete tshirts, and golden ratio rings. Head over to Zazzle for prime number mugs, math symbol ties, and math formula night lights. Finally, you can pop across the pond to U.K.'s Maths Gear where you can find a hyperbola clock, torus balloons, and those everpopular binary birthday candles. Remember it is only (the number of partitions of 8)days until Christmas!

Solvers of the Fortnight 
Problem
of the Fortnight 
A
light bulb at point B on the vertical line x
= 2 illuminates a region that is partially occluded by
an arc of the circle x^{2} +
y^{2} =
1. How high must the light bulb be if the point (1.25, 0) is on
the edge of the illuminated region? (Click on the picture to the
left to see an enlarged picture of this situation.)
Write your solution  showing all your work, please!  on a shadow and drop it by the Problem of the Fortnight slot outside Dr. Pearson's office (VWF 212) by 3:00 p.m. on Friday, December 8. As always, be sure to include your name and the name(s) of your professor(s)  e.g. Slip Ray Slope, Dr. Al Luminate  on your solution.
