In short
British scientists developed radar technology in 1935 as a method to detect aircraft at distance using radio waves. The breakthrough came from research led by Robert Watson-Watt at the National Physical Laboratory, who demonstrated that radio signals could bounce off moving objects and reveal their position. Within years, radar became the backbone of air defense systems that would prove decisive in World War II.
How it unfolded.
The five-minute version
What actually happened.
An invention is a unique or novel device, method, composition, idea, or process. An invention may be an improvement upon a machine, product, or process for increasing efficiency or lowering cost. It may also be an entirely new concept. If an idea is unique enough either as a stand-alone invention or as a significant improvement over the work of others, it can be patented. A patent, if granted, gives the inventor a proprietary interest in the patent over a specific period of time, which can be licensed for financial gain.
