Held over from an earlier show of Chinese artists, this is an installation of individually well-characterized, gaga old men, looking like a grotesque collection of senile world leaders, colliding at random in their wheelchairs, in a riotously funny display of photo-electric cell-activated dodgems.
THAT was also why relativistic physics had to come about– before the photo-electric phenomenon scientists thought that they had everything in physics figured out!

This photo-electric effect, as it is known, was first observed by Heinrich Hertz in the 1880s.
Electronically controlled machines incorporate photo-electric cells that automatically sense bends requiring snipping and pleating, and also dispense thermoplastic adhesive to bond the material in position.
The pH was initially adjusted to 7.0 and the temperature was kept constant at 35 C. Turbidity was measured at intervals with a Klett-Summerson photo-electric calorimeter, and the maximum specific growth rates were calculated from the kinetics of growth.
Although having decidedly furthered the de - velopment of the probabilistic interpretation of quan - tum phenomena through his early contributions to the photo-electric effect and through his statistical deriva - tion of Planck's formula for black-body radiation,
