The story of electric charge begins in ancient times. The Greeks were among the first to discover electrical phenomena. Around 600 BC, a Greek philosopher named Thales of Miletus observed that rubbing amber with fur would cause it to attract small objects like dust and feathers. This was the earliest known study of static electricity, … Read more
In the 18th century, the study of heat and temperature was a hot topic among scientists. One of the key figures in this field was Joseph Black, a Scottish scientist who made groundbreaking observations. He noticed that different substances required varying amounts of heat to achieve the same increase in temperature. This led him to … Read more
The story of water’s peculiar behavior begins in the mid-19th century. In 1859, a British scientist named W.J.M. Rankine made a groundbreaking discovery. He observed that when water freezes, it expands and occupies more space than it does in its liquid form. This was contrary to the common behavior of substances, which typically contract upon … Read more
The concept of materials expanding with heat has likely been observed since ancient times, as people noticed that hot days could cause doors to stick or metals to become more pliable. The scientific study of thermal expansion began during the Renaissance. This period marked the birth of modern science, with scholars starting to quantify and … Read more
