Carl Linnaeus stayed on Gotland for about a month, and then returned to Uppsala. During this expedition, they found 100 previously unrecorded plants. The observations from the expedition were later published in ', written in Swedish. Like ', it contained both zoological and botanical observations, as well as observations concerning the culture in Öland and Gotland. During the summer of 1745, Linnaeus published two more books: ' and '. ' was a strictly botanical book, while ' was zoological. Anders Celsius had created the temperature scale named after him in 1742. Celsius' scale was inverted compared to today, the boiling point at
Time–temperature superposition indicator of the quality of a relationship that has been computed from experimental data. The principle of time-temperature superposition requires the assumption of thermologically simple behavior (all curves have the same characteristic time variation law with temperature). From an initial spectral window ["ω", "ω"] and a series of isotherms in this window, we can calculate the master curves of a material which extends over a broader frequency range. An arbitrary temperature "T" is taken as a reference for setting the frequency scale (the curve at that temperature undergoes no shift). In the frequency range ["ω", "ω"], if the temperature increases
