The purpose of the COS Speakers Series is to provide a forum in which all members of the College of the Siskiyous faculty and staff can share insights into topics and activities that are of interest to them with the COS community and the general public. It is not meant to be used for the purpose of promoting a particular political or religious agenda. All presentations should be of interest to a wide audience and be consistent with the spirit of openness and inclusiveness that is central to the College's mission.

Gem Identification with Danielle Signor and Bill Hirt
Thursday, 18-Feb-2016 at 7:30pm in Science 210, Weed campus
How do gemologists identify the precious stones that people bring to them? What can they observe—without damaging a stone—to learn if it is natural or synthetic, if it has been treated to enhance its appearance, or if it is simply a “fake” made of glass? Danielle and Bill will address these and other questions as they describe and demonstrate a variety of the common techniques that gemologists use.
Gem Identification is open to the public and free of charge. It is part of the 2015-2016 season of the COS Speakers Series, which is presented as a public service by the COS staff. To learn more contact 530.938.5373.

Recent Events in Human Evolution is the first COS Speakers Series’ presentation of the 2015-2016 academic year. Subsequent presentations will explore topics ranging from the power of music to black holes.
During the academic year events in the series will typically begin at 7:30 PM on the third Thursday of each month on the Weed Campus. No talks will be held during December and January, however, because of the holiday season.
A list of presentation dates and working titles is given at right and will be updated as new information becomes available.
The 2015-2016 academic year marks the sixth season of the COS Speakers Series. As we move forward with new talks we also want to build an archive that will give interested members of the community a sense of the diversity of the series' past presentations. The title of each presentation is listed below and most are linked to a flyer that gives a brief summary of the talk and a little information about the speaker.

"The Committee": Rumor has it that the COS Speakers Series is organized by a secretive cabal of full- and part-time faculty members who apparently have way too much time on their hands.
If you have an idea for a future talk, might be interested in giving a presentation yourself or just want to contact the members of 'The Committee' we're told you can reach them at email@example.com.
