A thermal profile is a complex set of time-temperature data typically associated with the measurement of thermal temperatures in an oven (ex: reflow oven).

The thermal profile is often measured along a variety of dimensions such as slope, soak, time above liquidus (TAL), and peak.

Infrared radiation, or simply infrared or IR, is electromagnetic radiation (EMR) with longer wavelengths than those of visible light, and is therefore invisible, although it is sometimes loosely called infrared light.

It extends from the nominal red edge of the visible spectrum at 700 nanometers (frequency 430 THz), to 1000000 nm (300 GHz) (although people can see infrared up to at least 1050 nm in experiments).

Most of the thermal radiation emitted by objects near room temperature is infrared.

Like all EMR, IR carries radiant energy, and behaves both like a wave and like its quantum particle, the photon.

A thermometer is a device that measures temperature or a temperature gradient.

A thermometer has two important elements: (1) a temperature sensor (e.g. the bulb of a mercury-in-glass thermometer) in which some physical change occurs with temperature, and (2) some means of converting this physical change into a numerical value (e.g. the visible scale that is marked on a mercury-in-glass thermometer).

Thermometers are widely used in industry to control and regulate processes, in the study of weather, in medicine, and in scientific research.

A pyrometer is a type of remote-sensing thermometer used to measure the temperature of a surface.

Various forms of pyrometers have historically existed.

In the modern usage, it is a device that from a distance determines the temperature of a surface from the spectrum of the thermal radiation it emits, a process known as pyrometry and sometimes radiometry.

Whales are a widely distributed and diverse group of fully aquatic placental marine mammals.

They are an informal grouping within the infraorder Cetacea, usually excluding dolphins and porpoises.

Whales, dolphins and porpoises belong to the order Cetartiodactyla with even-toed ungulates and their closest living relatives are the hippopotamuses, having diverged about 40 million years ago.

The two parvorders of whales, baleen whales (Mysticeti) and toothed whales (Odontoceti), are thought to have split apart around 34 million years ago.

The whales comprise eight extant families: Balaenopteridae (the rorquals), Balaenidae (right whales), Cetotheriidae (the pygmy right whale), Eschrichtiidae (the gray whale), Monodontidae (belugas and narwhals), Physeteridae (the sperm whale), Kogiidae (the dwarf and pygmy sperm whale), and Ziphiidae (the beaked whales).
