The history of electromagnetism is a story of the discovery and understanding of the force that governs electricity and magnetism. English scientist Michael Faraday discovered in 1838 that an electric current produced a magnetic field, laying the foundation for the field of electromagnetism. In 1873, Scottish physicist James Clerk Maxwell discovered that electricity and magnetism are two different aspects of the same force . Maxwell's equations describe the behavior of electromagnetic waves, which include visible light, radio waves, and X-rays. In 1905, Albert Einstein used Maxwell's equations to explain the photoelectric effect. Einstein's theory of special relativity showed that time and space are relative concepts.
Early AI research focused on developing systems that could mimic or exceed the capabilities of human brains. This led to the development of various programming languages and AI applications designed specifically for this purpose. AI has been used by the military for years, but has only recently become more widely available to the general public in the form of smart personal assistants.
The article covers six interesting facts about technology, including that the average American checks their smartphone 46 times a day and that the first ever text message was sent in 1992.
Black holes are strange and powerful objects in the universe that are still not fully understood by scientists. They are incredibly dense, have a strong gravitational pull, and can be destructive. Some black holes are believed to power quasars, which are the most energetic objects in the universe.
