Fact of the week
As carbon dioxide (CO2) levels have risen from 280 parts per million in pre-industrial times to around 385 parts per million today, woody climbing vines have begun growing relatively faster than the trees they use as ladders and parasitize.

Physicists and EoE Contributors: Celebrate Year of Science 2009 with the Encyclopedia of Earth by authoring an article under this month’s theme: Physics and technology. Find a list of wanted articles here. Email Maggie Surface to contribute to the Encyclopedia of Earth.


Encyclopedia articles

Atom

The atom is the smallest part of the element that retains the chemical characteristics of the element itself. For our purposes, we can think of the atom as a sphere with a diameter of about 10−10 meters. This is about a million times smaller than the diameter of the period at the end of this sentence. If the atoms in your body were an inch in diameter, you would have to worry about bumping your head on the moon.

Niels Henrik David Bohr

Niels Henrik David Bohr (1885-1962), a Danish physicist who identified the fundamental structure of atoms and quantum mechanics. Building on the earlier theory of Ernest Rutherford, Bohr proposed that electrons travel only in certain successively larger orbits.

Albert Einstein

Albert Einstein (1879-1955), renowned German-American physicist who, in 1905, published three papers, each of which had a profound effect on the development of physics. One paper proposed the theory of special relativity, which provides a description for particles traveling at high speeds. The two postulates of the special theory of relativity were that the speed of light in a vacuum is constant and that the laws of physics are the same for all inertial reference frames.

Heat transfer

An object’s kinetic energy can be classified as internal or external. For example, a falling coin has a certain external kinetic energy that is related to its overall mass and to its velocity as it falls. The coin is also composed of particles that, like all particles, are moving in a random way, independent of the overall motion (or position) of the coin.

Technologyical innovation

Technology innovation is the process through which new (or improved) technologies are developed and brought into widespread use. In the simplest formulation, innovation can be thought of as being composed of research, development, demonstration, and deployment, although it is abundantly clear that innovation is not a linear process - there are various interconnections and feedback loops between these stages, and often even the stages themselves cannot be trivially disaggregated.
