Lawrence says... Did You Know?
  • Grace Hopper was the first digital computer programmer. She filed bug reports with real bugs). Grace Hopper appeared on Letterman and handed him 1 nanosecond.
  • The first computer computer programmer was Ada Lovelace?
  • Allegedly, one of the largest non-nuclear man-made explosions was due to a deliberate CIA bug?
  • Social and Educational Computing,Plato, and cross-platform multimedia browser, Mosaic, were pioneered at UIUC?
  • Some unsolved theoretical problems are worth 1 million dollars in prize money?
  • Computer Science includes numerous and varied sub-fields e.g. Artificial Intelligence, Graphics, Algorithms, Vision, Language, Robotic Path Planning, Human-Computer-Interaction (HCI), Mobile Computing, Operating systems, Simulation. Most of these are active research areas.
