File:Glasses 800 edit.png. What Does a Scientific Glass Blower Make? | Symbiartic. I came across so many interesting images last week researching my scientific glass blowing post that I thought I’d share a few more here. This is a blog about imagery after all, right? You’ll forgive my lack of song and dance, then? Michael Souza This is one of Michael Souza’s aluminosilicate creations. You’ll recall aluminosilicate glass is a notoriously difficult material to work with and Souza has made a name for himself doing just that.
This particular creation is a nuclear target cell for large particle accelerators such as CEBAF at Jefferson Lab and SLAC at Stanford. A nuclear target cell by Michael Souza The cells are filled with highly magnetic helium gas at pressures approaching 300 psi and put into a magnetic field so as to align the atoms and their nuclei.

Glass Chain. The Glass Chain or Crystal Chain sometimes known as the "Utopian Correspondence" (German: Die Gläserne Kette) was a chain letter that took place between November 1919 and December 1920.
It was a correspondence of architects that formed a basis of expressionist architecture in Germany. It was initiated by Bruno Taut.

Heavenly illumination: The science and magic of stained glass | Andy Connelly | Science. Life, like a dome of many coloured glass, stains the white radiance of eternity – Percy Bysshe Shelley I often find peacefulness in a soaring stone church, a cool open place to sit and contemplate. The giant trunk-like pillars and the gentle play of the light cast through the stained glass create a shaded garden of stone and multicoloured light. Stained glass windows are never static. In the course of the day they are animated by changing light, their patterns wandering across the floor, inviting your thoughts to wander with them. They were essential to the fabric of ancient churches, illuminating the building and the people within, both literally and spiritually.
The history of stained glass dates back to the middle ages and is an often underestimated technical and artistic achievement. Glass itself is one of the fruits of the art of fire. The history of glass The earliest manufacture of glass probably occurred in Mesopotamia during the early part of the third millennium BC. Enamels. Gridlinked. Gridlinked is Neal Asher's first novel, published by the Macmillan Publishers imprint Pan Books in 2001. It contains elements of the technological inventiveness of hard science-fiction with a more contemporary political plotline.
The novel follows the exploits of Earth Central Security agent Ian Cormac, as he attempts to discover who or what is behind the destruction of the Runcible on a remote colony. Cormac drops an investigation into Polity separatists on Cheyne III, and takes the starship Hubris to the ruined world of Samarkand to directly oversee the investigation there. Having been directly "gridlinked" to the Polity A.I. network for too long, Cormac has been slowly losing his humanity, and takes the opportunity of this particular mission to disconnect and solve the mystery the old-fashioned way.
Detailed plot summary[edit] Cormac takes a space shuttle to Cereb, the location of the nearest Runcible. There is no explanation as to the Maker, its origins or motivations. Ending[edit] Glass. Studio glass by Tyler Hopkins, demonstrating many of the essential properties of glass Glass is an amorphous (non-crystalline) solid material that exhibits a glass transition, which is the reversible transition in amorphous materials (or in amorphous regions within semicrystalline materials) from a hard and relatively brittle state into a molten or rubber-like state.
Glasses are typically brittle and can be optically transparent. The most familiar type of glass is soda-lime glass, which is composed of about 75% silicon dioxide (SiO2), sodium oxide (Na2O) from soda ash, lime (CaO), and several minor additives. The term glass is often used to refer only to this specific use. In science, however, the term glass is defined in a broader sense, encompassing every solid that possesses a non-crystalline (i.e. amorphous) structure and exhibits a glass transition when heated towards the liquid state. Silicate glass[edit] Ingredients[edit] Physical properties[edit] Optical properties[edit] Color[edit] Fused quartz. A fused quartz sphere manufactured for use in a gyroscope in the Gravity Probe B experiment. It is one of the most accurate spheres ever manufactured, deviating from a perfect sphere by no more than 40 atoms of thickness. It is thought that only neutron stars are smoother.
Production[edit] Feedstock[edit] Fused quartz is produced by fusing (melting) high-purity silica sand, which consists of quartz crystals. Quartz contains only silicon and oxygen, although commercial quartz glass often contains impurities. Fusion[edit] Melting is effected using at approximately 2000 °C using either an electrically heated furnace (electrically fused) or a gas/oxygen-fuelled furnace (flame fused). Product quality[edit] Fused quartz is normally transparent, the process of fusion results in a material that is translucent.
Applications[edit] Most of the applications of fused silica exploit its wide transparency range, which extends from the UV to the near IR.

Electron micrograph of the 2009 H1N1 influenza virus 3D representation of the influenza virus Look at the two images of the H1N1 influenza virus - the strain that causes swine flu - on the right. The first is a three-dimensional illustration that shows different parts of the virus in different colors - the hemagglutinin protein on the surface is blue, for example, while the RNA and associated proteins inside the virus are green. The second is an electron micrograph image of the same virus. UK artist Luke Jerram was intrigued by the fact that both types of images false in their own way.
Here is Jerram's sculpture of the H1N1 influenza virus: As he explained in an interview with the Wellcome Trust: The series is a reflection of my interest in how images of phenomena are represented and presented to the public.
