modern world

Modern history, the modern period or the modern era, is the global historiographical approach to the timeframe after the Post-classical history.^[1][2]Modern history can be further broken down into periods:

• The early modern period began approximately in the early 16th century; notable historical milestones included the European Renaissance and the Age of Discovery.^[3][4]
• The late modern period began approximately in the mid-18th century; notable historical milestones included the French Revolution, American Revolution, the Industrial Revolution, and the Great Divergence. It took all of human history up to 1804 for the world's population to reach 1 billion; the next billion came just over a century later, in 1927.^[5]
• Contemporary history is the span of historic events that are immediately relevant to the present time.

MODERN TECHNOLOGY ADVANTAGES AND DISADVANTAGES

Modern technology is simply an advancement of old technology, the impact of technology in modern life is unmeasurable, we use technology in different ways and sometimes the way we implement various technologies ends up harming our lives or the society we leave in. What we call modern technology is technically not so new in most cases. For example, mobile phone technology has evolved with years, nowadays we use smartphones which have been an advancement of an ordinary mobile phone.

Science and philosophy

Replacing the classical physics in use since the end of the scientific revolution, modern physics arose in the early 20th century with the advent of quantum physics,^[74] substituting mathematical studies for experimental studies and examining equations to build a theoretical structure.The old quantum theory was a collection of results which predate modern quantum mechanics, but were never complete or self-consistent. The collection of heuristic prescriptions for quantum mechanics were the first corrections to classical mechanics.Outside the realm of quantum physics, the various aether theories in classical physics, which supposed a "fifth element" such as the Luminiferous aether,^[78] were nullified by the Michelson-Morley experiment—an attempt to detect the motion of earth through the aether. In biology, Darwinism gained acceptance, promoting the concept of adaptation in the theory of natural selection. The fields of geology, astronomy and psychology also made strides and gained new insights. In medicine, there were advances in medical theory and treatments.
