The Asch conformity experiments shows how group pressure can persuade an individual to conform to an obviously wrong opinion (1951) B. F. Skinner's demonstrations of operant conditioning (1930s–1960s) Harry Harlow's experiments with baby monkeys and wire and cloth surrogate mothers (1957–1974) Stanley Milgram's experiments on human ...
Experiments can vary from personal and informal natural comparisons (e.g. tasting a range of chocolates to find a favorite), to highly controlled (e.g. tests requiring complex apparatus overseen by many scientists that hope to discover information about subatomic particles). Uses of experiments vary considerably between the natural and human ...
The Free High School Science Texts (FHSST) organization is a South African non-profit project, which creates open textbooks on scientific subjects. Textbooks are edited to follow the government's syllabus, and published under a Creative Commons license (CC BY [1]), allowing teachers and students to print them or share them digitally.

The equipment used for pressure experiments depends on whether the pressure is to be increased or decreased and by how much. A vacuum pump is used to remove the air out of a vacuum vessel for low-pressure experiments. High-pressures can be created with a piston-cylinder apparatus, up to 5 GPa (50 000 bar) and ~2000 °C.
For the first 3 experiments the period was about 15 minutes and for the next 14 experiments the period was half of that, about 7.5 minutes. The period changed because after the third experiment Cavendish put in a stiffer wire. The torsion coefficient could be calculated from this and the mass and dimensions of the balance.
Cornu's equipment allowed him to monitor high orders of extinction, up to the 21st order. Instead of estimating the intensity minimum of the light being blocked by the adjacent teeth, a relatively inaccurate procedure, Cornu made pairs of observations on either side of the intensity minima, averaging the values obtained with the wheel spun ...
The Golden Book of Chemistry Experiments is a children's chemistry book written in 1960 by Robert Brent and illustrated by Harry Lazarus and published by Western Publishing as part of their Golden Books series.
