The ratification of the 13th Amendment to the US Constitution (freedome of slaves), and the Civil Rights Act of 1964
Since 1776, over 40 million Americans have served in the military across various conflicts and peacetime periods. This includes service in the Revolutionary War, the Civil War, World Wars, Korea, Vietnam, the Gulf War, and recent conflicts in the Middle East. The number reflects the contributions of individuals from diverse backgrounds throughout U.S. history.
Estimating the total number of soldiers wounded since 1776 is challenging due to the many conflicts and wars involving the United States. However, it is likely in the millions, considering major conflicts such as the Civil War, World Wars, and more recent engagements. The most accurate statistics are often specific to individual wars, but comprehensive data across all conflicts is limited. For example, the Civil War alone saw approximately 500,000 wounded.
Civil War buttons are a popular collector's piece and are usually remnants of original Union or Confederate uniforms. Since these were spun from wool, buttons are the only thing left.
Probably rivers, since one of them is named, "the army of the Potomac."
Firstly, since which civil war? Secondly, scientists have made millions of contributions since most of them. They include huge advances in astronomy, nuclear physics (almost anything involving it, in fact), chemistry (the isolation and study of many compounds, identification of chemical structures, new elements discovered or created), biology (medicine in particular), economics (so much more advanced), mathematics.. virtually anything you can think has been largely contributed to since then.
Since glass was invented, the scientists were able to create the microscope. If this was never invented, the scientists would never have been able to discover cells.

Aristotle did not make direct contributions to cell theory since this concept was developed much later in the 17th century. However, his ideas on biology and classification laid the foundation for the study of living organisms, including cells. His observations and writings on plant and animal structures influenced later scientists who contributed to the development of cell theory.

No, electricity was not invented by a Black person. Electricity as a concept has been around since ancient times, with contributions from various scientists and inventors throughout history. The modern understanding and harnessing of electricity can be attributed to multiple inventors and scientists.
Richard A. Proctor did not discover the Ursa Major constellation; it has been known since ancient times. Proctor was an English astronomer who made contributions to popularizing astronomy and writing about celestial objects and phenomena.
Since the Chinese teach Communism there are no positive contributions.
Since 1923.
Since tornadoes are a weather phenomenon most of the scientists who study them are meteorologists. Most storm chasers are not scientists.
