The cyclotron, developed by Lawrence and Livingston in 1932, is a machine that accelerates charged particles like protons, so that they can be used in atom-smashing experiments. Because the principles of this accelerator are involved in the cyclic motion of charged atomic particles in a uniform magnetic field, the device is called cyclotron.

A globally convergent (the so-called convexification) algorithm was developed for coefficient inverse problems (CIPs) with time/frequency-dependent data. Convexification is extended to the case of a CIP for an elliptic equation with data generated by the source, running along a straight line. The data are incomplete, since they are given only at a part of the boundary. Applications to electrical impedance …

This is an important technique in modern farming, which was developed as farmers learnt from the mistakes made in the 19th and early 20th centuries. Then many people thought that the Earth’s resources were boundless, and in colonies and other territories around the world, they cleared forests and grasslands to make way for new farms.
