A wave is a disturbance that propagates through space and time, usually with transference of energy. While a mechanical wave exists in a medium (which on deformation is capable of producing elastic restoring forces), waves of electromagnetic radiation (and probably gravitational radiation) can travel through vacuum, that is, without a medium.
Waves travel and transfer energy from one point to another...

Abstract
Ultra-cold neutron (UCN) production and storage in a liquid-4He source are evaluated by means of multi-group neutron-transport analysis. Using the cross-section model developed by the authors, a set of group constants for liquid 4He at many different temperatures down to 0.1 K is generated. Major results thus obtained are as follows. As the temperature is decreased below about 0.5 K, the UCN density shows a saturation behavior because of no significant up-scattering and UCN loss by neutron #-decay only. Single down-scattering of a 1-meV neutron and also multiple scattering of a higher-energy neutron contribute largely to UCN production. A high UCN density of 12105
cm-3 is possible with a high reflectivity of a storage vessel, say over 0.9999.
http://en.wikipedia.org/wiki/Point-set_topology
In mathematics, general topology or
point-set topology is the branch of topology which studies properties of topological spaces and structures defined on them. It is distinct from other branches of topology in that the topological spaces may be very general, and do not have to be at all similar to
manifolds.
