The left-hand rule, a rule used in physics to determine the direction of magnetic force in a conductor, was developed in the 19th century by scientists such as John Fleming and Oliver Heaviside. However, the specific date of its invention is not precisely recorded.
The law of superposition was first proposed by the 17th-century geologist Nicolaus Steno. It states that in any undisturbed sequence of sedimentary rocks, the oldest layers are at the bottom, and the younger layers are at the top. This principle is fundamental in geology and paleontology for determining the relative ages of rock layers and the fossils contained within them. Steno's work laid the groundwork for modern stratigraphy and our understanding of geological time.
Some famous scientists who were contemporaries of Robert Hooke include Isaac Newton, Galileo Galilei, Rene Descartes, and Christian Huygens. These scientists made significant contributions to various fields like physics, astronomy, and mathematics during the 17th century.

The hypothesis that sedimentary strata were laid down in chronological order led to the development of the principle of superposition, which states that in any undisturbed sequence of rock layers, the youngest layer is on top and the oldest is on the bottom. This principle became a fundamental concept in geology and helped scientists understand the relative ages of rocks and the history of Earth's geologic processes.
Radiometric dating--the process of determining the age of rocks from the decay of their radioactive elements--has been in widespread use for over half a century. Relative dating is used to determine the relative ages of geologic strata, artifacts, historical events, etc.

Scientists developed seismographs in the late 19th century. The first seismograph was invented by John Milne in 1880.

The fifth century began on January 1, 401 AD, and ended on December 31, 500 AD. To determine how many years ago the fifth century was, we need to subtract the end year (500 AD) from the current year. As of 2023, the fifth century was 1523 years ago.
