The United States' Apollo moon landing in the late 1960s was the first step for mankind to set foot on a planet beyond the earth. Since then, the United States has gradually left the Soviet Union behind in terms of space exploration. After the emergence of the space shuttle, the chance of success for humans to travel to outer space has been greatly improved. Scientists predict that humans will carry out outer space travel after 2000 AD.

3. Television

In 1923, the picture tube, the soul of television, was born. Television technology was widely used in the 1940s, and the era of color television was ushered in in 1954. After the 1960s, most countries have established television stations. This square box has created countless happy moments for mankind.

4. Artificial Satellite

The first artificial satellite was successfully test-launched by the Soviet Union on October 4, 1957, followed by the American Explorer 1 on October 1, 1958. The test was successful on March 31. From then on, more and more of these artificial satellites that orbited with the rotation of the earth were floating outside the atmosphere. Artificial satellites originally used in military technology have gradually evolved into a family of satellites with different purposes such as communication, mapping, detection, and meteorology.

5. Aspirin

As early as the 15th century, Greek doctors used powder ground from willow bark as the ancestor of the herbal version of aspirin. By the end of the century, this formula for relieving body pain received unprecedented attention.
