Thomas Edison's greatest challenge was the development of a practical incandescent, electric light. Contrary to popular belief, he didn't "invent" the lightbulb, but rather he improved upon a 50-year-old idea. In 1879, using lower current electricity, a small carbonized filament, and an improved vacuum inside the globe, he was able to produce a reliable, long-lasting source of light.
Thomas Edison's greatest fear was reportedly the dark. He was known to be afraid of the dark, which is ironic given his inventions revolutionized the use of light.
The light bulb paved the way for other inventions such as the telephone switchboard, the phonograph, and the motion picture camera. These technologies relied on the ability to have artificial lighting to function effectively.
Some inventions that involve physical changes include the light bulb (converting electrical energy into light), the refrigerator (changing the temperature to preserve food), and the microwave (using electromagnetic waves to heat food).
James Watt primarily focused on improving steam engines, and is best known for his improvements to the steam engine that made it more efficient and practical for industrial use. While he made other minor inventions, such as a steam indicator and a copying machine, Watt's main contributions were in the field of steam power.
Some inventions that have been developed using atoms include atomic clocks, nuclear reactors, and scanning tunneling microscopes. These inventions rely on the precise manipulation and understanding of atomic structures to function effectively.

When he was writing things, he made use of the inventions the quill pen, ink and paper at his writing desk. No doubt when sitting down to a meal he made use of such inventions as pottery, cast metal, brewed beverages and so on. Ever since the times of cavemen, people have employed inventions of some kind or other constantly in their daily lives.
