Mirror for the Great Rosse Telescope
William Parsons, the Third Earl of Rosse built a series of telescopes at Birr Castle his home in Ireland. After casting metal 3-foot diameter mirrors he decide to makes ones 6 feet across. This mirror weighing over 4 tonnes is the only surviving example of the five mirrors that Lord Rosse cast between 1842--5. The resulting reflecting telescope, known as the 'Leviathan of Parsonstown' had a tube 15m long suspended between massive masonry walls. Rosse used this great telescope to try and determine the nature of nebulae, misty patches in the sky. He was the first to discover that some had spiral forms, now known to be remote and massive islands of stars like our own Milky Way Galaxy.

Duke University Physics Department, Science Night 2010
Sep 22 four student volunteers from the Physics Dept’s Outreach Group joined the Chemistry Dept’s Outreach Group for “An Evening of Science” in front of the French Science Building. Using demonstrations, the students explained two topics they learned in mechanics, Newton’s 3rd Law and Waves.
The image here is of a Ruben’s Tube. The pipe has a speaker inserted in one end and the other end plugged. There is a line of small holes drilled along the top and a gas valve on the front – basically a long grill with a speaker in one end. (The Outreach group can cook hot dogs, too!) After turning on the gas and lighting, an amplified function generator sends a sine wave to the speaker at one of the tube’s resonant frequencies. The flame heights will vary according to the sound pressure level at each hole thus the standing wave in flames.
There is only room on this set of shelves because I have a bunch of books in a closet in my front room still. Plus, the unread books. Plus, some of the stacks around the house.....

Looking north across the river. The Science Museum of Minnesota is directly opposite, and the Wiggington Pavilion is at my back.

pseudo-cosplay photoshoot wearing science blues... don't bug me about accuracy, i know every inaccuracy involved in this shoot. twas just for fun.

Would have been far better had a boat not gone by! This, unfortunately, was the only shot I was able to take due to the dreaded error 99. Damn you canon!

Scenes from the Team Science workshop held at the Virginia Institute of Marine Science's Eastern Shore Lab in Chincoteague Island,Virginia in November 2018.
Virginia Sea Grant, VIMS, Virginia Commonwealth University, University of Virginia, and the University of Central Florida selected 36 graduate students to participate in a pilot professional development workshop focusing on team problem-solving and research fieldwork through a trans-disciplinary approach.
