Boyle's law of the gas, and "k" is a constant. The equation states that the product of pressure and volume is a constant for a given mass of confined gas and this holds as long as the temperature is constant. For comparing the same substance under two different sets of conditions, the law can be usefully expressed as The equation shows that, as volume increases, the pressure of the gas decreases in proportion. Similarly, as volume decreases, the pressure of the gas increases. The law was named after chemist and physicist Robert Boyle, who published the original law in 1662. This relationship
The Man Who Was Thursday in Latin, and a title given to Jesus. (Usually a title given to the Virgin Mary.) "The Man Who Was Thursday" inspired the Irish Republican politician Michael Collins with the idea "if you didn't seem to be hiding nobody hunted you out". Martin Gardner edited "The Annotated Thursday", which provides a great deal of biographical and contextual information in the form of footnotes, along with the text of the book, original reviews from the time of the book's first publication and comments made by Chesterton on the book. A less thorough annotation was done for the edition of the novel
