CHARLIE, LARRY and AMITA sip champagne and eyeball the new Physics-Math-Astronomy (PMA) Chair, DR. MILDRED FRENCH. She chats with the PROVOST near a microphone. PROVOST Ladies and Gentlemen... The Provost introduces Dr. French, Charlie whispers to Amita. PROVOST (CONT'D) We celebrate the appointment of Dr. Mildred French to the Physics-Math-Astronomy Chair. CHARLIE I just want you to know I'm-- I'm willing to-- to go to bat for you with Mildred. PROVOST (CONT'D) Her work in Algebraic Geometry led her to String Theory with a strong connection to Cosmology-- In other words she speaks your languages. All of them. AMITA Thanks, Charlie. Dr. Mildred French steps to the microphone.

This Demonstration shows zero level sets of
various algebraic surfaces and their
cutaway views.

CHARLIE You're asking about cancer clusters- - statistically rare. More likely, it's a case of Texas sharpshooting. MEGAN Am I about to be mocked? CHARLIE Say there's a guy who's never held a gun before-- he aims at the side of a barn and shoots. AUDIENCE VISION. GUNSHOTS PECK HOLES IN THE SIDE OF AN OLD RED BARN. CONCENTRIC CIRCLES OF A TARGET ARE THEN DRAWN AROUND THE MAIN CLUSTER OF SHOTS TO MAKE IT SEEM LIKE THE SHOOTER WAS A MARKSMAN. SHOTS ON THE PERIPHERY ARE IGNORED. CHARLIE (V.O.) (CONT'D) When he's done, he draws a circle around the closest shots, ignores the other and declares he's-- END AUDIENCE VISION. MEGAN A Texas Sharpshooter.

Take a set of random points. In the "Texas sharpshooter problem," the smallest circle that contains three of
the points is found. In the "bomb problem," the smallest circle that contains all the points is found.

Don and Meeks walk with Charlie as a backhoe digs up earth about fifty yards from the sinkhole. Agents with shovels and breathing masks stand by. CHARLIE We found Benzene residue in the sinkhole. It's probably what killed the elderly lady and caused the rashes in the children. DON Benzene from the aggregate.

The Demonstration computes the residue curve map for the ternary mixture benzene-toluene-p-xylene. When you change the
locator's position, a new residue curve is computed and displayed. Residue curve maps play an important role in the
conceptual design of distillation columns.

LARRY FIRE IN THE HOLE!!! A controlled EXPLOSION! Everything SHAKES! Howard jumps. HOWARD MEEKS What the hell?! CHARLIE We're locating the source of the acid. Water flows from high to low so we know it's in the northeast sector above the sinkhole-- but we can get a precise location with seismic imaging.

This Demonstration shows the propagation of elastic waves, commonly known as seismic waves. Two types of seismic waves are shown here: pressure waves (P-waves) and shear waves (S-waves). The P-wave is longitudinal, and so oscillates along the direction of the wave propagation, while the S-wave shakes perpendicular to the travel direction.
