| physics | The science of nature, or of natural objects; that branch of science which treats of the laws and properties of matter, and the forces acting upon it; especially, that department of natural science which treats of the causes (as gravitation, heat, light, magnetism, electricity, etc) that modify the general properties of bodies; natural philosophy. Chemistry, though a branch of general physics, is commonly treated as a science by itself, and the application of physical principles which it involves constitute a branch called chemical physics, which treats more especially of those physical properties of matter which are used by chemists in defining and distinguishing substances.

| health physics | The science concerned with problems of radiation protection relevant to reducing or preventing radiation exposure, and the effects of ionizing radiation on humans and their environment. (12 Dec 1998) |
| starfire tokamak | <radiobiology> A conceptual design study of a modular tokamak reactor that operates in a steady-state condition while using conventional power-generating systems. (09 Oct 1997) |
| tokamak | <radiobiology> (Acronym created from the Russian words, TOroidalnaya KAmera ee MAgnitnaya Katushka, or Toroidal Chamber and Magnetic Coil.) Because the tokamak is the most common research machine for magnetic confinement fusion today, we provide several descriptions from various sources. One of several types of toroidal discharge chamber in which a longitudinal magnetic field is used to confine a plasma. The tokamak is distinguished by a plasma current running around the torus, which generates a stabilising poloidal magnetic field. An externally-applied vertical magnetic field is also used to achieve plasma equilibrium. An axisymmetric toroidal confinement device characterised by a strong toroidal magnetic field (1-10 Tesla) and a toroidal plasma current (several mega-Amps) that leads to a modest poloidal magnetic field. The plasma current is usually induced by ramping a current in a large solonoid along the symmetry axis of the tokamak. This is an inherently pulsed mode of operation, and other mechanisms of current drive are under investigation. A three component magnetoplasma toroidal construct in which the poloidal magnetic component is provided by a toroidal plasma current. The other two components are coil driven, namely, the vertical field (which opposes the major radial expansion) and the toroidal field (which acts to provide a stiff guide field for the plasma to gain more magnetohydrodynamic stability. Note: It is better to think that the toroidal or longitudinal field stiffens the plasma as against flopping or kinking, while the plasma current driven poloidal (locally azimuthal) field provides confinement pressure. Actually, the toroidal field interacting with plasma diamagnetism may also contribute to a magnetic bouyancy, which is a sort of UN-confinement (it actually gives the plasma a tendency to expand radially outward in the equatorial plane). Based on an original Soviet design, a device for containing plasma inside a torus chamber by using the combination of two magnetic fields - one created by electric coils around the torus, the other created by intense electric current in the plasma itself, which also servers to heat the plasma [partially].

| tokamak fusion test reactor | <radiobiology> Large tokamak at Princeton, first machine to use 50-50 mix of D-T fuel, current world's record holder in fusion energy production. Largest tokamak in the United States. (09 Oct 1997) |
| los alamos meson physics facility | <radiobiology> Physics research facility at Los Alamos National Lab, major site for U.S. Muon-catalysed fusion research in the 1980s. May be shut down soon. (09 Oct 1997) |
| Mariotte's experiment | An experiment in which one looks fixedly with one eye (the other being closed), at a black dot on a card, on which is also marked a black cross; as the card is moved to or from the eye, at a certain distance the cross becomes invisible but appears again as the card is moved further; this proves the absence of photoreceptors where the optic nerve enters the eye.

| Weber's experiment | If the peripheral end of the divided vagus nerve is stimulated the heart is arrested in diastole. (05 Mar 2000) |
| control experiment | An experiment used to check another, to verify the result, or to demonstrate what would have occurred had the factor under study been omitted. See: control, control animal. (05 Mar 2000) |
| Scheiner's experiment | A demonstration of accommodation; through two minute holes in a card, separated from each other by less than the diameter of the pupil, one looks at a pin; at a short distance from the eye the pin appears double; as it is moved from the eye a point is found where it appears single, and beyond which it remains single for the emmetropic eye, but for the myopic eye it soon again becomes double.

| hershey-chase experiment | <molecular biology> A landmark experiment done in 1952 which showed that DNA is the hereditary material. The experiment, done by Martha Hershey and Alfred Chase, involved allowing a bacteriophage which contained DNA labelled with 32P (an isotope of phosphorus) and a protein labelled with 35S (an isotope of sulphur) to attach to some bacteria. When the bacteriophages were later removed, they found that it was the 32P (and thus the DNA) that had entered the bacterial cells rather than the 35S (indicating the protein). (09 Oct 1997) |
| pulse-chase experiment | An experiment in which an enzyme, a metabolic pathway, a culture of cells, etc., interacts with a brief addition (pulse) of a labelled compound followed by its removal and replacement (chase) by an excess of unlabelled compound. (05 Mar 2000) |
| Stensen's experiment | Compression of the abdominal aorta of an animal promptly causes paralysis of the posterior portions of the body since the blood supply to the lumbar cord is almost entirely shut off. (05 Mar 2000) |
| Nussbaum's experiment | Exclusion of the glomeruli of the kidney from the circulation by ligation of the renal artery in animals, such as the frog, that have a renal portal system to maintain circulation to the tubules. (05 Mar 2000) |
