Some inventions during the second half of the twentieth century that changed the world included the following: the telephone, radio, television and the automobile. The telephone allowed communication between countries, giving birth to telecommunications infrastructure. Radio allowed the world to listen in to transmissions from distant locations, thereby allowing for news and entertainment. Television gave the world a means of seeing another person or object, something that was impossible during the nineteenth century.
Other great inventions included the following: the electric air motor, the internal combustion engine, the screw pump, the compound bow drill, the drills, wrenches, push rods and nails. Some of these things were invented by ordinary men, while others were invented by great inventors who had a vision. Henry Ford took an interest in vehicles and invented the Ford Motor Company. The air motor was invented by Sir Richard Branson, who used it to drive across Africa without a vehicle. The screw pump was invented by Wilberforce Brown.
Many different inventions altered the way we live our lives. One of the most important was the discovery of fire. People all over the world were able to use this amazing force to warm their homes. They could cook food, heat their homes and even use it to forge metal into tools. Without this discovery, many people would not have been able to survive in the cold winters of the middle ages.
Another great invention was the light bulb. This amazing invention enabled humans to produce light without using the sun. It also allowed people to control the amount of light produced. This made it possible to see in the dark. Without the light bulb, people would have had to go outdoors in the dark to find what they needed.
These are just some of the many great inventions that shaped the world. Some of them have changed our lives forever. Others have changed men’s lives for the better. Without some of the inventions mentioned above, the world may not be as we know it. Some of these inventions have even spurred new advances.
