At Oak Ridge National Laboratory, Conceptual drawing shows a flexible organic photovoltaic made from an acceptor of PCBM (buckyball with earth) and the donor of deuterated conducting polymer. The polymer blend in the device (bottom) will harvest the sunlight to generate electrical power. (carbon:blue; sulfur: yellow; hydrogen: white; deuterium: purple).

(Lion's rock) is an ancient rock fortress and ruins of a castle situated in central Matale District of Sri Lanka. It is a popular tourist destination and also popular for the ancient paintings (frescos) very similar to the paintings in Ajanta Caves of India. It was built during the reign of King Kasyapa (477 – 495 AD) and one of the seven World Heritage Sites in Sri Lanka.
Sigiriya may have been inhabited through prehistoric times. It was used as a rock-shelter mountain monastery from about the 5th century BC, with caves prepared and donated by devotees to the Buddhist Sangha. The garden and palace were built by Kashyapa. Following Kasyapa's death, it was again a monastery complex up to about the 14th century, after which it was abandoned. The ruins were discovered in 1907 by British explorer John Still. The Sigiri inscriptions were deciphered by the archeologist Senarath Paranavithana who published a renowned two volume work, published by Oxford, known as "Sigiri Graffiti". He also wrote the popular book "Story of Sigiriya".Still further interpretations have the site as the work of a Buddhist community, with no military function at all. This site may have been important in the competition between the Mahayana and Theravada Buddhist traditions in ancient Sri Lanka
Sigiriya rock is the hardened magma plug from an extinct and long-eroded volcano.
Sigiriya consists of an ancient castle built by King Kasyapa during the 5th century AD. The Sigiriya site has the remains of an upper palace sited on the flat top of the rock, a mid-level terrace that includes the Lion Gate and the mirror wall with its frescoes, the lower palace that clings to the slopes below the rock, and the moats, walls and gardens that extend for some hundreds of metres out from the base of the rock.
The site is both a palace and fortress.
The upper palace on the top of the rock includes cisterns cut into the rock that still retain water. The moats and walls that surround the lower palace are still exquisitely beautiful.
Sigiriya is considered as one of the most important sites of urban planning of the first millennium, the site plan is considered very elaborate and imaginative. The planning had combined concepts of symmetry and asymmetry to intentionally interlock the geometrical plan and the natural form of the surroundings. The west side of the rock lies a park for the royals which is symmetrically planned, the park contains water retaining structures which includeds sophisticated sub/surface hydraulic systems of which some are working even today. The south contains a man made reservoir, these were extensively used from previous capital of the dry zone of Sri Lanka. Five gates were placed at entrances. The more elaborate western gate is thought to be reserved for the royals.
The Gardens
The landscape of the Sigiriya city is considered to one of the most important aspects of the site, the gardens are one of the oldest landscaped gardens of the world. Gardens take three distinct but linked forms they are Water, Cave and boulder gardens. The water gardens are the more sophisticated in design and can be seen in the western precinct. The water gardens contained pools of various depths with streams flowing over slabs of marble. Underground hydraulic systems provide water into the fountains which even operate today. Other water gardens found combines pavilions with water courses which were used to cool the pavilions. Boulder gardens had a different design concept to the water gardens, the gardens included pathways, pavilions etc.
* Sigiriya is used as the location of many of the events in the science-fiction novel The Fountains of Paradise by Arthur C. Clarke, although Clarke changed the name to Yakkagala in the book.
4. österreichische Citizen Science Konferenz
Die Österreichische Citizen Science Konferenz 2018 fand vom 01.-03. Februar an der Universität Salzburg statt. Organisiert wurde sie von der Universität Salzburg in Kooperation mit „Österreich forscht“, „Schweiz forscht“, „Bürger schaffen Wissen“, dem „Zentrum für Citizen Science“ und dem FWF.
Unter dem Motto „Generation Citizen Science“ lag der Fokus darauf , wie man Menschen für die Methode und für einzelne Projekte begeistern kann.

THE SILICON VERTEX TRACKER OF THE BABAR DETECTOR AT THE STANFORD LINEAR ACCELERATOR FACILITY.
THE SILICON VERTEX TRACKER IS THE HEART OF THE BABAR EXPERIMENT AT SLAC. HERE PHYSICISTS ARE PUTTING THE FINISHING TOUCHES ON IMPROVEMENTS TO THE DETECTOR. THE BABAR DETECTOR, PART OF SLAC'S B FACTORY SYSTEM, WILL PRODUCE B AND ANTI-B MESONS, PARTICLE-ANTIPARTICLE PAIRS SO THAT SCIENTISTS CAN INVESTIGATE THE MATTER-ANTIMATTER ASYMMETRY IN NATURE.

Dreyfuss + Blackford Architecture’s design for the Powerhouse Science Center re-envisions a historic riverfront structure as a hub for science education, exploration and promotion in the City of Sacramento. On the banks of the Sacramento River, the Science Center grows out from an abandoned power station building. As a principal component of the Riverfront activation, the Powerhouse Science Center anchors Robert T. Matsui Waterfront Park and borders the southern terminus of the 32-mile American River Bike Trail.
Vacant for over half a century, the structure undergoes a complete historic rehabilitation and the construction of a new floor level inside. A new two-story addition projects from the east side, containing a lobby, classrooms, offices and a cafe. A 110-seat planetarium is prominently on display with a zinc-clad hemispheric dome rising above the building’s mass. As representation of our place in the universe, the facade and building mass is sectioned by multiple planes, creating continuous vector lines that extend across the building and site. From satellites to world landmarks, the lines form connections with local and global points of interest.
The original PG&E Power Station B was designed in 1912 in the Beaux Arts Style by architect Willis Polk and was formally closed in 1954. It is on the National Register of Historic Places, California Register of Historic Places and the Sacramento Register of Historic & Cultural Resources. The Powerhouse Science Center is designed to achieve a USGBC LEED Rating of Silver.

May 23, 2010 -- Over 1,000 students participated in the 2010 undergraduate commencement ceremonies at the State University of New York at New Paltz, held in Old Main Quad on the campus of SUNY New Paltz on May 23, 2010. The graduation marked the final ceremony for outgoing college president Steven Poskanzer. Harvard Political Science Professor Gary King (‘80) returned home as the guest speaker.

Thought Id take a shot of Science World when it was green. After this shot my camera bag was stolen by two crack heads. This shot cost me around $800.00 dollars.

This is the aluminum outer case for a W80 warhead. It serves as a structural and protective container. Its mounting hardware allows it to be attached to a cruise missile. The Mod 1 (left) and Mod 0 [now inside the DARHT exhibit] warheads are nearly identical. The mounting and installation hardware for the cruise missile bodies are different, but little else.
W80
The W80 is the warhead used on the three types of cruise missiles in the U.S. arsenal. There are two modifications (mods):
Mod 1 on air-launched cruise missiles launched from bombers
Mod 0 on missiles, called Tomahawks, which can be launched from certain attack submarines sea-launched cruise

The first recipient of the residency staged under the auspices of the Art & Science Network is MarÃa Ignacia Edwards (CHL). She was selected from among the 140+ applicants from 40 countries and will be spending her residency at the European Southern Observatory (ESO) in Chile and at the Ars Electronica Futurelab in Austria. Picture is showing MarÃa Ignacia Edwards during her pre-visit in Chile, walking on the Star Track up to the Paranal Observatorium Platform.

Food Science students took a break from studying on May 10 to participate in a little friendly competition on the lawn outside Bradfield Hall.
The Food Science Olympics, organized by the Food Science Club included an egg toss, saltine cracker and fruit roll-up eating competitions, Jello relay, and melon bowling.
Here, students Clint Hervert and Bridgette Wunder face off in the fruit roll-up finale.
