Dynamical relations in the system of two objects with internal
Dynamical relations in the system of two objects with internal

... The two-object problem, i.e. determination of their trajectories, can be solved in principle, if interaction between them is known. On the other hand, Bertrand sets up an inverse problem of determining interaction with respect to known trajectories of motion of bodies ( [2]). As it is known, accordi ...

Seismometer

Seismometers are instruments that measure motion of the ground, including those of seismic waves generated by earthquakes, volcanic eruptions, and other seismic sources. Records of seismic waves allow seismologists to map the interior of the Earth, and locate and measure the size of these different sources.The word derives from the Greek σεισμός, seismós, a shaking or quake, from the verb σείω, seíō, to shake; and μέτρον, métron, measure and was coined by David Milne-Home in 1841, to describe an instrument designed by Scottish physicist James David Forbes.Seismograph is another Greek term from seismós and γράφω, gráphō, to draw. It is often used to mean seismometer, though it is more applicable to the older instruments in which the measuring and recording of ground motion were combined than to modern systems, in which these functions are separated.Both types provide a continuous record of ground motion; this distinguishes them from seismoscopes, which merely indicate that motion has occurred, perhaps with some simple measure of how large it was.The concerning technical discipline is called seismometry, a branch of seismology.
