What events and ideas spurred people to come up with thousands of inventions in the last 100 years?

Ron Hickman was a do-it-yourself enthusiast who damaged a chair being used to support a piece of wood he was sawing. Instead of merely being annoyed at the accident he set about designing and building a prototype of a combined workbench and sawhorse to prevent further damage to his furniture. This became the Workmate (Author(s): The Open University

Hacia una RV de Representaci?n Hiperrealista (Towards a VR of Hyper-realistic Representation)
The objetive of the proyect is the hiperrealistic simulation of scenarios on standard PCs. We use the same tools that are used by the entertainment industry (3d graphics engines) to get the highest level of realism possible in 3d worlds. By now, we are exploring only the audio and visual areas. The potencial of this 3d enviorments construction tools let us to create exploration enviorments for academic and professional implementation like commerce, tourism, education, communication, etc.

Even in images taken with the most modern equipment on a large telescope, it can be difficult to pick out the galaxies now known as 'active' from the other more normal galaxies. But if your telescope were equipped to examine the spectra of the galaxies, then the active galaxies would stand out. Normal galaxies contain stars that are generally similar to those in our own Galaxy; and spiral galaxies have additional similarities to the Milky Way in their gas and dust content. Active galax
