The space-time wormhole and time direction of travelling light
The investigation of Scharzschild solution using new one transform leads to the spherical solution of light path. Spherical solution forms space-time wormhole with finite throat. It was shown that wormhole throat diameter could by manipulated by changing value of Schwarzschild radius. Using symmetric formulation of Maxwell’s equations one can obtain the physical time negative solution. Detailed...
متن کاملTravelling bioethics
When there are no strikes or natural disasters, travelling usually is a pleasure. Some of us have returned from the annual conference of the American Society for Bioethics and Humanities in San Diego, while others have good memories of the 10th World Congress of Bioethics in Singapore last summer. But not only bioethicists are travelling, bioethics itself is as well, following the globalization...
متن کاملWatching a Travelling Wave Watching a Travelling Wave
Travelling waves are a feature of many spatio-temporal series. The use of single side band filtering and the complex singular value decomposition to isolate such waves is described. As with other applications of the singular value decomposition, such as principal components, the results can be difficult to interpret. In the case of travelling waves, however, a dynamic graphical display using co...

متن کاملTravelling Wave Linear Accelerators
Communicated b y y. D. Cockcroft; MS. ABSTRACT. Acceleration of electrons by means of an electroma,onetiic wave travelling down a circular corrugated tube is considered. The relevint properties of corrugated tubes are derived and the factors influencing electron enxgies. Some numerical results are also quoted for a wavelength of 10 cm. The problems of high energy accelerators arc &scussed brief...
