Dial-A-Moon The animation archived on this page shows the geocentric phase, libration, position angle of the axis, and apparent diameter of the Moon throughout the year 2013, at hourly intervals. Until the end of 2013, the initial Dial-A-Moon image will be the frame from this animation for the current hour.

Victorian Era Names, A Writer's Guide
circa 1840's-1890's Being a compilation drawn from old census and vital statistic records. A large part of creating a good set of characters in fiction writing is giving your imaginary populace good names. The right name resonates on the tongue and lingers in the mind, as just the right "fit" for who that heroic - or despicable - person was. Who can forget "Captain Ahab" and his manic pursuit of the Great White Whale, or the plain-spoken, earthy spirit of "Tom Sawyer," or the stern lyricism of "Sherlock Holmes?" The same holds true for writing stories set in the 1800's.
Australian Aboriginal Astronomy: When Giant Fish Leaves the Sky
I would like to introduce our readers to a video presentation made by John Morieson and Alex Cherney about the astronomy of the Boorong clan (of the Wergaia language in northwest Victoria). John Morieson is an historian in Victoria who has spent many years researching the astronomy of the Boorong and other Victorian Aboriginal groups. He completed an MA thesis at the University of Melbourne in 1996, where he reanalysed the work of William Edward Stanbridge regarding Boorong astronomy. Alex Cherney is an amateur astronomer and astrophotographer in Melbourne. He has produced amazingly beautiful photography of the sky and has won several awards and honourable mentions in astrophotography competitions, including the STARMUS astrophotography contest, the David Malin awards, and several NASA "Astronomy Picture of the Day" posts.
This is What Happens When You Run Water Through a 24hz Sine Wave
What!? How is this even possible? Because science, my friends. Brusspup’s (previously) latest video explores what happens when a stream of water is exposed to an audio speaker producing a loud 24hz sine wave. If I understand correctly the camera frame rate has been adjusted to the match the vibration of the air (so, 24fps) thus creating … magic zigzagging water.
Water has properties that are positively electrifying!
Most people certainly understand how important water is for our survival, but we often overlook how weird it can be. I can compile a short, though not exhaustive, list off the top of my head: Water is less dense in solid form (ice) than in liquid form. Ice cubes float, and ice forms at the top of lakes, protecting the fish and other organisms below from the cold.
