...concept of a celestial sphere which is attached to the sky rather than to the surface of the Earth. This equatorial system has coordinates known as Right ascension and Declination and is used for controlling advanced telescopes such as COAST and for specifying an object’s position uniquely. We will also briefly consider a second system: the Altitude–Azimuth (Alt-Az)...

...concept of degeneracy. In this context, degeneracy means that there is more than one quantum state with the same energy. In quantum mechanics, all particles display wave-like behaviour. In particular, any particle has a characteristic wavelength, known as the de Broglie wavelength, defined by lamda sub dB equals h divided by p Equation label: (1) where h is Planck’s...

...concepts of the influence of predators, sensory communication, coevolution and niche separation. Answer Tree-dwelling mammals may escape terrestrial predators but they are exposed to others, notably birds of prey. Many tree dwellers are nocturnal and there are advantages for some (e.g. flying foxes) in congregating in large numbers, which may have the advantage of...
