The magnetic field of Mars estimated from the data of plasma measurements by Soviet artificial satellites of Mars

The dimensions of the obstacle forming the shock wave of Mars are estimated by use of electron trap data from Mars 2, 3, and 5. The mean altitude of the obstacle at the subsolar point can be convincingly explained if the obstacle is the magnetosphere of Mars. On the assumption that Mars has its own dipole magnetic field, the magnetic moment of Mars is estimated, Mm approximately equal to 2 x 10 to the twenty second power gs x cubic cu

Simulation of Coherent Diffraction Radiation Generation by Pico-Second Electron Bunches in an Open Resonator

In this report we present new approach for calculation of processes of diffraction radiation generation, storage and decay in an open resonator based on generalized surface current method. The radiation characteristics calculated using the developed approach were compared with those calculated using Gaussian-Laguerre modes method. The comparison shows reasonable coincidence of the results that allows to use developed method for investigation of more complicated resonators

Magnetic field and plasma inside and outside of the Martian magnetosphere

Simultaneous magnetic and plasma measurements, carried out by wide angle plasma detectors in the Mars environment, are compared in order to identify regions with significantly different physical properties. Magnetograms and ion spectra indicate changes in the magnetopause and magnetosphere of Mars that are associated with the dynamic pressure effect of the solar wind

How to make a stick and other recipes for unnatural disaster

“It is incumbent upon him [Don Quixote] to fulfill the promise of the books. It is his task to recreate the epic, though by a reverse process: the epic recounted (or claimed to recount) real exploits, offering them to our memory; Don Quixote on the other hand, must endow with reality the signs-without-content of the narrative. His adventures will be a deciphering of the world: a diligent search over the entire surface of the earth for the forms that will prove that what the books say is true. Each exploit must be a proof: it consists, not in a real triumph – which is why victory is not really important – but in an attempt to transform reality into a sign. Don Quixote reads the world in order to prove his books. And the only proofs he gives himself are the glittering reflection of resemblances.” Michel Foucault, (on Don Quixote) The Order of Thing
