Most dramatically, the Galileo space probe was deliberately destroyed at the end of its mission by crashing it into Jupiter, to avoid the possibility of contaminating the Jovian moon Europa with bacteria from Earth.

Most frequently, classical elements refer to ancient beliefs inspired by natural observation of the phases of matter.

Most of the information used by astronomers is gathered by remote observation, although some laboratory reproduction of celestial phenomenon has been performed ( such as the molecular chemistry of the interstellar medium ).

Most of them derive from early models formulated by David Marr and James Albus, which were motivated by the observation that each cerebellar Purkinje cell receives two dramatically different types of input: On one hand, thousands of inputs from parallel fibers, each individually very weak ; on the other hand, input from one single climbing fiber, which is, however, so strong that a single climbing fiber action potential will reliably cause a target Purkinje cell to fire a burst of action potentials.

Most older estimates of average timing of menarche were based on observation of a small homogeneous population not necessarily representative of the larger population, or based on recall by adult women, which is also susceptible to various forms of error.

Most research involves the observation of animals, without disturbing them, and includes studies on general behaviour, on feeding and on parental care of offspring either in the Trust grounds or overseas.

Most striking were the " beavertail " observation cars of the 1930s and the " Skytop Lounge " observation cars by industrial designer Brooks Stevens in the 1940s.

Most motor skills are thought to be acquired through practice ; however, mere observation of the skill has led to learning as well.

Most synoptic observation charts are expressed in SI units, with the exception of aforementioned wind speeds, which must be converted for the purposes of calculation.

Most land-surveying applications are now carried out by satellite observation.

Most of these lessons were done informally by discussions and observation until March 1, 1902 when he was given orders to report to Marine Barracks, Washington, D. C. on March 7, 1902 for further assignment in the western Pacific.

Most aperture synthesis interferometers use the rotation of the Earth to increase the number of baseline orientations included in an observation.

Most aperture synthesis interferometers use the rotation of the Earth to increase the number of different baselines included in an observation ( see diagram on right ).

Most of the range, including the control tower and four observation towers are in Gedney, but it does overlap with Holbeach to the west.

Most scholars either move the observation upon which he based this forward by one cycle of Sothis to 2781 ( July 19 ), or reject the assumption that the document in question indicates a rise of Sothis at all.

Most of these can be summarized by a simple observation: a phylogenetic data matrix has dimensions of characters times taxa.

Most fluorescence microscopes in use are epifluorescence microscopes ( i. e., excitation and observation of the fluorescence are from above ( epi –) the specimen ).

Most early units had little equipment and relied on careful nursing and observation.

Most observation missions send a small number of long-term monitors ( known as LTOs ) for a period of six to eight weeks.

Most lesions are monostotic, asymptomatic and identified incidentally and can be treated with clinical observation and patient education.

Most German defenders survived the barrage in shell-proof observation posts and bunkers and were able to man frontline defences when the assault began.

Later Boris Almazov made an important observation in a speech: " Most of our writers who describe the lives of Russian state officials and people from governmental spheres have only fleeting experiences of this kind ... More often than not they've served only formally, hardly noticing the faces of their chiefs, let alone those of their colleagues.
