atmospheric science

Atmospheric chemistry is a branch of atmospheric science in which the chemistry of the Earth's atmosphere and that of other planets is studied. It is a multidisciplinary field of research and draws on environmental chemistry, physics, meteorology, computer modeling, oceanography, geology and volcanology and other disciplines. Research is increasingly connected with other areas of study such as climatology. The composition and chemistry of the atmosphere is of importance for several reasons, but primarily because of the interact ...

Broadly defined, geobiology is an interdisciplinary field of scientific research that explores interactions between the biosphere and lithosphere or atmosphere. Investigators from numerous fields are involved in geobiologic research, including, but not limited to, such disciplines as: paleontology, microbiology, mineralogy, biochemistry, sedimentology, genetics, physiology, geochemistry (organic and inorganic), and atmospheric science. One major subdiscipline of geobiology is geomicrobiology, an area of study that focuses on investiga ...

Accretion is increase in size by gradual addition of smaller parts. This term is used in the following fields: In atmospheric science for growth of a precipitation particle by the collision of an ice crystal or snowflake with a supercooled liquid droplet that freezes upon impact. In astrophysics, accretion is the gravitational process by which bodies such as planets and stars form from gas and dust. See accretion theory, accretion disc. Other related

The ancient Greeks regarded air as one of the four elements, but the first scientific studies of atmospheric composition began in the 18th century. Chemists such as Joseph Priestley, Antoine Lavoisier and Henry Cavendish made the first measurements of the composition of the atmosphere. In the late 19th and early 20th centuries interest shifted towards trace constituents with very small concentrations. One particularly important discovery for atmospheric chemistry was the discovery of ...

In 1986, the use of single beam optical tweezers was first reported in the scientific literature by Arthur Ashkin et al Opt. Lett. 11, 288-290 (1986) from Bell Labs. In 1997, Steven Chu made use of the optical tweezing techniques and applied to the cooling and trapping of atoms. This led to the the 1997 Nobel Prize in Physics award; one of the recipients, Steven Chu worked with Ashkin at Bell Labs on both atomic cooling and optical tweezers, co-authoring the seminal Optics Letters paper^{See also:}

The American Association for the Advancement of Science was created on September 20, 1848 in Pennsylvania. It was a reformation of the Association of American Geologists and Naturalists. The society chose William Redfield as their first president. According to the first constitution [1] which was agreed to at the September 20th meeting, the goal of the society was to promote scientific dialogue in order to allow for greater scientific collaboration. By doing so the association aimed use resources to conduct science with increased efficiency ...
