Math Field Day: Help Wanted

The math department's annual Mathematics Field Day will be held Saturday April 17. This event invites high school students from Central California for a day of mathematical competitions. There is a need for student volunteers to help make this event possible. Any student interested should contact Amy Peterson (email or you can leave a note in her mailbox in the math department office).

Colloquium

Mark Thursday March 25, 2:10pm, on your calendars for a special colloquium talk. Professor Don Chakerian, from UC Davis, will speak on some elementary properties of ellipses that are not well know and perhaps deserve wider publicity. Dr. Chakerian has won national distinguished teaching awards and is known for excellent exposition. His wide body of mathematical research on convex geometry includes many simple, elegant solutions to classical problems. The room location for the talk will be in the next issue of the Math Major.

Job Opportunities

Summer Opportunities for Students

There are several exciting summer research and/or study opportunities in mathematics for students. For a particulars, visit maa web site . Opportunities include Research Experience for Undergraduates, the NASA Academy and Internships and Research Opportunities in National Facilities and Laboratories.

Graduate Study at CSU Fresno

If you are graduating with a Bachelor degree in mathematics this year, you are probably eligible to enroll in the Master of Arts in mathematics program at CSU Fresno. For more information, contact Dr. Hugo Sun in the mathematics department.

A Mathematical Quote

"The discovery in 1846 of the planet Neptune was a dramatic and spectacular achievement of mathematical astronomy. The very existence of this new member of the solar system, and its exact location, were demonstrated with pencil and paper; there was left to observers only the routine task of pointing their telescopes at the spot the mathematicians had marked."

--James R. Newman

(The location of Neptune was determined by Urbain Jean Joseph Le Verrier (1811-1877).)

Problem Corner

Problem 3.9: A child on a pogo stick jumps 1 foot on the first jump, 2 feet on the second jump, 4 feet on the third jump, ..., 2n-1 on the nth jump. Can the child get back to the starting position by a judicious choice of directions?

Solution to Problem 3.9: No. The child will always "overshoot" the starting point, because after n jumps the distance for the starting point to the child's location is at most 1 + 2 + 4 + ... + 2n-1 = 2n - 1 feet. Since the (n+1)st jump is 2n feet, it can never return the child exactly to the starting point.

There was only one solution submitted, but it was not correct.

New Problem

Problem 3.10: (Due Thursday March 11, 3 p.m.) Let C be a circle with center O and Q a point inside C different from O. Where should the point P be located on the circumference of C to maximize the measure of angle OPQ?

Solutions may be delivered to the math department office (for Dr. Cusick) or by e-mail.
