CSO
Participated the Onizuka Science Day 2010 
Onizuka Science Day
was
held on 23th of January 2010. At the CSO booth, we had a small
parabolic dish
demonstration to show how a telescope collect radiation from distant
astronomical objects along with CSO's telescope model and a computer
that shows a short movie of
the observatory. For the small parabolic dish
demonstration, by dropping a ping-pong ball down on the good surface of
the
parabolic dish which sat against the gravity, people learned the ball
was bounced up at the focus position always. For the parabolic
dish demonstration, we used the 1.2 m parabolic dish donated by Oceanic
Time Warner
Cable located in Hilo in 2006. We are so grateful for their warm
hearted
donation and their support for our public educational outreach efforts.
This year, Walter Steiger, Ed Bufil, Brian Force, Ruisheng Peng, and
Hiroko
Shinnaga participated the Onizuka Science Day from the CSO.

Brian Force explains to a participant of the Onizuka Science day
how
submillimeter radiation from space will be guided into the optics of
the 10.4 meter Leighton telescope at the CSO.

a telescope collects light or radio wave from the Universe.

is trying out the radio dish demonstration using a ping-pong ball to
trace radio wave to be guided to an instrument mounted on a telescope.

radio-dish demonstrations at the CSO booth.
