This was not a practical language translator, but it was an impressive science fair project for the early 1960s. Mims wrote an article for the December 1987 issue of Modern Electronics describing his homebrew analog computer complete with schematics and photographs. [12] Mims entered Texas A&M University in the fall of 1962 as a physics major.
Experimental Design Diagram (EDD) is a diagram used in science to design an experiment.This diagram helps to identify the essential components of an experiment. It includes a title, the research hypothesis and null hypothesis, the independent variable, the levels of the independent variable, the number of trials, the dependent variable, the operational definition of the dependent variable and ...
The T-V diagram of the rubber band experiment. The decrease in the temperature of the rubber band in a spontaneous process at ambient temperature can be explained using the Helmholtz free energy = where dF is the change in free energy, dL is the change in length, τ is the tension, dT is the change in temperature and S is the entropy.

Electrostatic machines are typically used in science classrooms to safely demonstrate electrical forces and high voltage phenomena. The elevated potential differences achieved have been also used for a variety of practical applications, such as operating X-ray tubes, particle accelerators, spectroscopy, medical applications, sterilization of food, and nuclear physics experiments.

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 ...
1886: Heinrich Hertz succeeds in proving the existence of electromagnetic waves for the first time – now the groundwork for wireless telegraphy and radio broadcasting in physical science is laid. 1887: Unaware of Charles Sumner Tainter's experiments, German-American Emil Berliner has his phonograph patented. He used a disk instead of a ...
