Hubble in IMAX 3D
AVATAR was my first and second(!) IMAX 3D movie.
IMAX is bringing another fantastic movie... it is about the hubble space telescope

Journey: From and Back to Home
I was completely absorbed by the following video... Journey from Home to eternity and back to home.
After you go out of the solar system, you are in void. tranquility prevails and you are alone in there... navigating away from your home. The journey is not so easy as it was fantasized.

Adaptive Evolution and Darwinian Selection in Robots
Natural selection: is it the law or consequence due to the constraints provided in the situation?
It is "the law" if you think nature as an agent at work and that requires some law to work on. On the other hand it is the consequence if you view it with the concept of "natural process". The difference is subtle: do you conceive it as a work done by an agent or a continuous process?
Whatever it is, one thing is sure that Darwinian theory of natural selection is true for agents in the play ground. Be it living beings, or robots.
The understanding of nature and appreciation to it becomes rather huge once you have the capacity to build and mimic "natural behavior".
Scientists have been working on adaptive and evolutionary robots with capabilities to learn and hence are able to realize the Darwinian selection rule in such robotic agents as the consequence of such learning and adaptive behavior.
See some video...

Saturn's Ring through Mobile camera @ Observatory
Braving the Cold of First of February is not an easy thing to do. But if students make their mind, they will do it.
:)
Despite scattered snow in the beginning and in the end, we were lucky to see Mars and Saturn (and Moon of course!) Mars was visible for only few minutes after we started. Mars was playing hide and seek with us. We gave up on it as it was setting and clouds would never be clear on that side.
Stunningly my mobile could take the picture of Saturn with its ring distinctly visible. My bigger camera could not get anything better because of auto focus feature...
Here are some pictures of the Events...

Phil Erner, adjusting the telescope... Flash photography was prohibited... I took few anyway!
It started snowing again, after we were done.

Stargazing @ SUNY Albany -- II
As a part of our Stargazing Events, We invite you to next event on Monday, Feb 1, 2010.
We will see three planets and our moon in the next stargazing session on Monday morning, Feb. 1, starting at 5:30 AM, which is around dawn.
Overcast skies blocked our session on Sunday. It is impossible to predict the weather with certainty; to learn why, take Fluid Mechanics (physics 472/572) or Bayesian Analysis (physics 551).
This early morning session will be a real treat. We can see Saturn, still plenty high toward the southwest. Six of its famous satellites may be in view about the planet's equator, while Iapetus appears to the lower right.
Our Moon is the most dazzling object to view at night through the telescope. On Monday morning it is a waning gibbous, nearing the western horizon.
Mars will be setting as we arrive, in view to the unaided eye but probably out of the telescope's sight. Someday we'll have to catch it up close; but this morning belongs to Mercury.
The sun's closest planet will give its best view for a while on Monday morning around 7. Not to get our hopes too high: up just before sunrise, Mercury may not reach the telescope's sight line before solar glare washes it away.
Please dress warmly as the observatory is outdoors! While waiting for a turn to view you may wish to wait in the warmer hallway.
If the weather isn't clear then we will cancel. Twitter AlbanyStarGaze for updates.
