Air Flow – Euler Equation

Pretty simple PDEModels the

pressure on an airplane wing (or whatever) while in motion

Has been improved for efficiency (Navier-Stokes)

Computing NowC/C++LinuxPlenty of power on desktop to

write/debug/runOpen Source graphics packages high-gradeCheap top-rate graphics hardware

On To High Energy PhysicsFermi National Accelerator LaboratoryParticle PhysicsAcceleratorsDetectorsQuarks, Protons, Neutrinos, etc.My tenure there coincided with the

exponential growth of high-speed desktop computing

We all had many duties, my specialty was graphical interfaces

Large Particle DetectorBasically a cylinder consisting of hundreds of thousands of Components. The particle beam runs through the middle.The proton & anti-proton collide at the speed of light, andBreak apart in predictable fashion.

Neutrinos - MiniBooNENeutrinos are

basically massless particles

They can be generated by a beam or the sun

The color and size of the ball, and the shape of the distribution, tell the physicist what’s going on.

My jobWrite/improve/maintain/port Graphical

User Interfaces (GUI’s)Work with the physicists to find out what

is useful/notKeep up with computing technology to

make them as useful and cost-effective as possible (programs migrated from SGI to SunOS to Linux/PC over the years)
