Meeting Notes 12/03/15

Webmaster's note: Something I found particularly interesting and enjoyable about last week's meeting was that, while the lecture given by Dr. Fraser went a few minutes overtime, the members who didn't have immediate correspondences to satisfy were more than willing to stick around and listen. I am continually amazed (but never surprised) at the passion for science displayed by the club.

Science in the News



Science in the News Policy Changes

It has come to the attention of the club that recent Science in the News segments have been coming from untrustworthy or unmentioned sources. This has caused an increase in skepticism for a time meant to be spent in marvel and enlightenment. It is being asked that Science in the News segments are from now on sourced by a credible outlet. Thank you!

General Relativity

Daniel and Ben held up an impressively heavy text brought in by Dr. Fraser
as the lecture was carried out. 
The club sat audience to Dr. Fraser giving a lecture on general relativity today. He has provided me with a wonderful reference on the 1935 derivation of e=mc^2 by Albert Einstein from California Polytechnic State Univ., accessible here.




Gravitational Lensing

Just as the lenses on eyes bend light to form an image, gravitational lensing refers to the occurrence of light being reflected off of an enormous gravitational field, imaging things like distant galaxies. Sometimes, the distortion is large enough to display more than one image of the same galaxy, called "multiple imaging" in this description by the University of Tennessee (Knoxville).

"Here is another example of a gravitational lens called the Einstein Cross . In this image, a single object appears as four objects. A very distant quasar is thought to be positioned behind a massive galaxy. The gravitational effect of the galaxy has created multiple images through gravitational lensing on the light from the quasar. The stars in the foreground galaxy also seem to be acting as gravitational lenses, causing the images to change their relative brightnesses in these two photographs taken three years apart (UTK)."

Miscellaneous News

WOODINVILLE HIGH SCHOOL, DECEMBER 03-- Science enthusiast Daniel Shorr discovered a nap location that is on its way to revolutionizing classroom nap theory and to boot furthers research on the extent of student fatigue even when the webmaster has a camera. It is notable that no countertops were harmed in this ground-breaking demonstration.
