Historically, the definition of a scientific instrument has varied, based on usage, laws, and historical time period. [1] [2] [3] Before the mid-nineteenth century such tools were referred to as "natural philosophical" or "philosophical" apparatus and instruments, and older tools from antiquity to the Middle Ages (such as the astrolabe and pendulum clock) defy a more modern definition of "a ...

The reason for the rotation was a cause of much scientific debate in the ten years following the invention of the device, [1] [2] but in 1879 the currently accepted explanation for the rotation was published. [3] [4] Today the device is mainly used in physics education as a demonstration of a heat engine run by light energy.
Alcohol burners are preferred for some uses over Bunsen burners for safety purposes, and in laboratories where natural gas is not available. Their flame is limited to approximately 5 centimeters (two inches) in height, with a comparatively lower temperature than the gas flame of the Bunsen burner.
