For Thursday's assignment we had to make a list of what we thought were the " Greatest Engineering Achievements of the Twentieth Century", and after thinking about it for a long time, I narrowed my list down to those that I though were most important (namely those that changed our way of life). The final list follows.
- Internet (I wouldn't be writing this blog if it wasn't invented)
- Television
- Telephone/Cell-Phone
- Computer
- Word Processor
- Printer
- DVD/USB drive
- Laser
- Electronics (Integrated Circuit, Microchip, Microprocessor)
- Medical Technologies (Defibrillator, Dialysis, Pacemaker, Magnetic Resonance)
- Credit Card
- Air Conditioning (I'm enjoying it right now!)
- Radio
- Airplane
- Plastic
- Robotics
- Penicillin
- Photocopier
- Car
- Home appliances (washing machine, microwave, dryer, dishwasher, vacuum...)
The order of the list is arbitrary, and below are some other interesting inventions from this time period that were also key to the development of humankind to this present moment:
- Zipper
- Push-through tab
- Monopoly (Many Whartonites owe their major to this board game)
- Slinky
- Crayons
- Toaster
- Fortune cookies
- Yo-Yo (I think this was invented then...)

Now some serious ones...
- Atomic Bomb
- Electronic Microscope
- Helicopter
- Nuclear energy
