The award speech for Edison, a model of cherishing time, is:
Edison dedicated his life to the history of human development. Even though life was so unsatisfactory, he still quietly gained a little bit of happiness in life. Even if the society is so dark, he still burns himself resolutely and lights up the world. The scientist Comrade Edison made contributions to the country. His contribution to mankind created a bright future. Edison was the greatest and an example for mankind to learn from.
Main achievements:
As early as 1801, a British chemist named Humphry Davy used platinum wire to produce electricity in the laboratory; in 1810, He also invented the "electric candle" that was illuminated by the arc generated between two energized carbon rods. This was considered the earliest prototype of the electric light.
After nearly 30 years of research, another British electrical engineer, Joseph Swan, made a vacuum bulb using carbon filaments that emit electricity in December 1878. He applied for a patent in the UK in 1880 and in 1881 His incandescent light bulb was officially launched in 2001. Perhaps due to insufficient assessment of market demand and insufficient investment, Swann's electric light was never promoted and the patent was eventually acquired by Edison.
