  2. Matter - Wikipedia

    en.wikipedia.org/wiki/Matter

    It is fair to say that in physics, there is no broad consensus as to a general definition of matter, and the term "matter" usually is used in conjunction with a specifying modifier. The history of the concept of matter is a history of the fundamental length scales used to define matter. Different building blocks apply depending upon whether one ...

  3. Biological roles of the elements - Wikipedia

    A large fraction of the chemical elements that occur naturally on the Earth's surface are essential to the structure and metabolism of living things. Four of these elements (hydrogen, carbon, nitrogen, and oxygen) are essential to every living thing and collectively make up 99% of the mass of protoplasm. [1]

  5. Intrinsic and extrinsic properties - Wikipedia

    en.wikipedia.org/wiki/Intrinsic_and_extrinsic...

    [2] In biology, intrinsic effects originate from inside an organism or cell, such as an autoimmune disease or intrinsic immunity. In electronics and optics, intrinsic properties of men (or systems of devices) are generally those that are free from the corn field of various types of non-essential defects. [3]

    Atomic, molecular, and optical physics (AMO) is the study of mattermatter and light–matter interactions, at the scale of one or a few atoms [1] and energy scales around several electron volts. [2]: 1356 [3] The three areas are closely interrelated.

  9. History of molecular theory - Wikipedia

    en.wikipedia.org/wiki/History_of_molecular_theory

    In the Timaeus, Plato, following Pythagoras, considered mathematical entities such as number, point, line and triangle as the fundamental building blocks or elements of this ephemeral world, and considered the four elements of fire, air, water and earth as states of substances through which the true mathematical principles or elements would ...
