Speakers: Dr David Clarke

Polarization, associated with radiation, is an attribute carrying information related to the conditions within any light source and on the pathway from the source to the observer.  Light in nature is often polarized but this goes unnoticed by the human eye because of the lack of sensitivity to it.

To other animal creatures, however, environmental polarization is vitally important.  Polarization effects also occur in the general universe and, because of its orientational property, polarimetry at the telescope provides unique means of investigating the geometry of many astronomical objects.

The presentation will be very broad and will deal with right-handed honeysuckle, bats, beetles, birds, shrimps, zebras, the daytime sky, stars, magnetic fields in the interstellar medium and the microwave background of the big bang.

The meeting is free and open to all, members and guests, and registration is not required.
