The discovery of infrared radiation is ascribed to William Herschel, the astronomer, in the early 19th century. Herschel published his results in 1800 before the Royal Society of London. Herschel used a prism to refract light from the sun and detected the infrared, beyond the red part of the spectrum, through an increase in the temperature recorded on a thermometer. He was surprised at the result and called them "Calorific Rays". The term 'Infrared' did not appear until late in the 19th century.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What device did Herschel use to discover the infrared?
Ah, so.. a prism

Treaties may be seen as 'self-executing', in that merely becoming a party puts the treaty and all of its obligations in action. Other treaties may be non-self-executing and require 'implementing legislation'a change in the domestic law of a state party that will direct or enable it to fulfill treaty obligations. An example of a treaty requiring such legislation would be one mandating local prosecution by a party for particular crimes.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): A treaty requiring local prosecution by a party for particular crimes is an example of which type of treaty?
Ah, so.. non-self-executing
