The Kardashev scale ranks a civilization’s technological advancement, with Type I harnessing all power on a planet, Type II harnessing all power from a star, and Type III harnessing all power in a galaxy. Type IV and Type V civilizations consume the power of a galactic supercluster and the entire universe, respectively. Earth is currently […]
William Smith noticed a correlation between rock strata and fossils in 1815, leading to the creation of the geological time scale. The scale is divided into eras, periods, and epochs, with names based on where fossils were found. Radioactive dating allows for precise identification of fossil age. The geological time scale has its origins in […]
The Hamilton Anxiety Rating Scale measures the severity of physical and mental anxiety symptoms and evaluates the effectiveness of anti-anxiety medications and therapies.

The process for arriving at the final scale is largely unknown, with several stories circulating. Fahrenheit is not documented as a Freemason, and the Fahrenheit scale continues to be used in the United States. […]
The Planck scale is a very large energy scale or a very small size scale where quantum effects of gravity become important. Physicists are interested in learning more about it, but it represents a fundamental limit on how small distances we can probe. The Planck energy is almost unimaginably large, and a particle accelerator powerful […]
The pH scale measures acidity or alkalinity of a solution from 0 to 14, with 7 indicating neutrality. SPL Sørensen introduced the concept in 1909. Soil pH affects gardening success, and pH is important in determining wine quality and paper acidity. Natural pH indicators include red cabbage, and indicators like methyl violet are used for […]
An engineering scale is a ruler used by engineers to create ratio drawings. It has six measuring surfaces and is more accurate than an architect’s scale. The scale is marked with progressively smaller units of measure and can reproduce designs at different ratios. While CAD has replaced hand drawing in some areas, an engineering scale […]

Different types of sleep scales are used to evaluate sleepiness, including those that address daytime sleepiness, disease-specific scales, and age-specific scales. The Stanford Sleepiness Scale and Epworth Sleepiness Scale measure daytime sleepiness, while the Medical Outcomes Study Sleep Scale attempts to find the cause of sleepiness. Parkinson’s patients have their own specific scales, and there […]
The Liebowitz Social Anxiety Scale is a questionnaire survey that measures the intensity of a patient’s social anxiety or phobia. It consists of 24 items that specify certain social situations and patients rate their fear and avoidance on a scale of zero to three. A higher score indicates a higher degree of social anxiety.
