RE: absorptance
Absorptance is a measure of the amount of light, or alternatively other electromagnetic radiation, which is absorbed by a particular substance or surface upon which the light is incident. It quantifies the capacity of an object to take in energy from electromagnetic radiation. It is typically represented as a ratio or percentage of the incident radiation that is absorbed.

RE: wolfram
Wolfram is a chemical element, also known as tungsten, with the symbol W and atomic number 74. It is a hard, rare metal that is found naturally on Earth, mostly in the form of chemical compounds. The element is the heaviest metal to have a known biological role.
Wolfram is also the name of a multi-disciplinary company, Wolfram Research, which is best known for creating the Mathematica software and Wolfram Alpha answer engine. The company was founded in 1987 by mathematician and computer scientist Stephen Wolfram.

RE: soft tree fern
The soft tree fern, scientifically known as Dicksonia antarctica, is a type of fern that grows in a tree-like form. This species is characterized by a thick, fibrous, and soft trunk, large spreading fronds that can reach several meters in length, and a generally slow growth rate. It is native to parts of Australia and commonly found in cool, damp environments. Despite its name, the soft tree fern does not develop true wood as trees do, but instead possesses a softer, spongier interior. The fern is well-adapted to forest ecosystems and plays an important role in these habitats, providing shelter to many smaller creatures and helping to maintain soil health.

RE: lawn tennis
Lawn tennis is a racket sport commonly known as tennis, that can be played individually against a single opponent (singles) or between two teams of two players each (doubles). It originated in England during the 19th century, and its name stems from the fact that it was initially played on grass lawns. Players use a tennis racket to strike a hollow rubber ball, covered with felt, over a net and into the opponents court, with the objective of the game being to play the ball in such a way that the opponent is unable to return a valid shot.

RE: oropharynx
The pharynx (plural: pharynges) is the part of the throat behind the mouth and nasal cavity, and above the esophagus and trachea (the tubes going down to the stomach and the lungs). It is found in vertebrates and invertebrates, though its structure varies across species. The pharynx carries food and air to the esophagus and larynx respectively. The flap of cartilage called the epiglottis stops food from entering the larynx.
In humans, the pharynx is part of the digestive system and the conducting zone of the respiratory system. (The conducting zone—which also includes the nostrils of the nose, the larynx, trachea, bronchi, and bronchioles—filters, warms and moistens air and conducts it into the lungs). The human pharynx is conventionally divided into three sections: the nasopharynx, oropharynx, and laryngopharynx. It is also important in vocalization.
In humans, two sets of pharyngeal muscles form the pharynx and determine the shape of its lumen. They are arranged as an inner layer of longitudinal muscles and an outer circular layer.
