Science questions

The wavelength is commonly designated by the Greek letter lambda (λ).

UV radiation was discovered in 1801 when the German physicist Johann Wilhelm Ritter observed that invisible rays just beyond the violet end of the visible spectrum darkened silver chloride-soaked paper more quickly than violet light itself.

“In vitro” means the medical procedure takes place in the laboratory, opposite to “in vivo” - meaning “in the body”.

The Leeuwenhoek-medal is the most prestigious prize in the field of Microbiology. It has been awarded every 10 years since 1877 to a scientist who has made the most important contributions to Microbiology during the last 10 years. The first 13 medals were awarded by the Royal Netherlands Academy of Arts and Sciences.

In analytic geometry, an asymptote of a curve is a line such that the distance between the curve and the line approaches zero as one or both of the x or y coordinates tends to infinity. In projective geometry and related contexts, an asymptote of a curve is a line which is tangent to the curve at a point at infinity.The word asymptote is derived from the Greek which means "not falling together".

Busicom was a Japanese company that owned the rights to Intel's first microprocessor, the Intel 4004, which they created in partnership with Intel in 1970. Busicom asked Intel to design a set of integrated circuits for a new line of programmable electronic calculators in 1969. In doing this, they spurred the invention of Intel's first microprocessor to be commercialized, the Intel 4004. Busicom owned the exclusive rights to the design and its components in 1970 but shared them with Intel in 1971.

The hemipterology is the branch of entomology that studies the order Hemiptera, including bedbugs, squashbugs, and aphids. The Hemiptera or true bugs are an order of insects comprising some 50,000 to 80,000 species of groups such as the cicadas, aphids, planthoppers, leafhoppers, and shield bugs. The name "true bugs" is sometimes limited to the suborder Heteroptera.

The green tint found in most tempered glass is a result of iron used in the production of glass sheets, where it is added as an ingredient to act as a lubricant. In fact, except in manufacturing processes designed to minimize iron use to avoid the green tint, you’ll find that green cast in all sheets of glass–not just tempered glass

Glucagon is a peptide hormone, produced by alpha cells of the pancreas. The pancreas releases glucagon when the concentration of insulin in the bloodstream falls too low. It works to raise the concentration of glucose and fatty acids in the bloodstream, and is considered to be the main catabolic hormone of the body. It is also used as a medication to treat a number of health conditions. Its effect is opposite to that of insulin, which lowers the extracellular glucose.

The cerebellum (Latin for "little brain") is a major feature of the hindbrain of all vertebrates. In humans, the cerebellum plays an important role in motor control. It may also be involved in some cognitive functions such as attention and language as well as in regulating fear and pleasure responses. Based on the surface appearance, three lobes can be distinguished within the cerebellum: the anterior lobe (above the primary fissure), the posterior lobe (below the primary fissure), and the flocculonodular lobe (below the posterior fissure).
