PHOTO: EAST NEWS/SCIENCE PHOTO LIBRARY Earth as a water drop, conceptual computer artwork. Earth depicted as a drop of water causing a splash in the 'cosmic ocean'. This could represent Earth's relative insignificance with respect to the scale of the universe.

PHOTO: EAST NEWS/SCIENCE PHOTO LIBRARY Electron-hydrogen scattering simulation. Plot of part of the wavefunction describing electron-hydrogen scattering when an electron impacts a hydrogen atom, as simulated by a supercomputer. The large oscillations (green) are where one electron moves away from the nucleus and the other stays bound to it. The smaller oscillations (blue) are where both electrons move away from the nucleus (i.e. the hydrogen atom is ionised). This simulation was produced at the National Energy Research Scientific Computing Center (NERSC), based at the Lawrence Berkeley National Laboratory, California, USA.

PHOTO: EAST NEWS/SCIENCE PHOTO LIBRARY Nuclear fusion plasma simulation. Three-dimensional supercomputer simulation of plasma particle drift orbits in a tokamak nuclear fusion generator. A tokamak uses strong magnetic fields to produce the torus-shaped plasma shown here. Practical problems, such as plasma instabilities, are modelled in simulations like this. This simulation was produced by the SuperLU program used in the NIMROD project, producing much faster results. The simulation was run at the National Energy Research Scientific Computing Center (NERSC), based at the Lawrence Berkeley National Laboratory, California, USA.

PHOTO: EAST NEWS/SCIENCE PHOTO LIBRARY Particle accelerator beam simulation. Supercomputer simulation showing the tracks of particles in a beam at a particle accelerator. This is the simulation at a stage after hundreds of snapshots of the beam had been taken ad overlaid on the display. The lines and sphere are the tracks of individual particles selected for display. The cluster of dots in the background is the beam itself. The colour-scale at left indicates particle velocities. This simulation was produced at the National Energy Research Scientific Computing Center (NERSC), based at the Lawrence Berkeley National Laboratory, California, USA.

PHOTO: EAST NEWS/SCIENCE PHOTO LIBRARY Earth's gravity well. Computer artwork of the Earth, showing its gravity well as a distorted grid below. A gravity well is the the gravitational potential field around a massive body. It is the pull of gravity that bodies such as planets and stars exert on their surroundings.

PHOTO: EAST NEWS/SCIENCE PHOTO LIBRARY Confocal light microscope, artwork. Confocal microscopy uses fluorescent dyes to highlight tissues, cellular structures and proteins in the samples being analysed. A laser beam (blue lines, source at left) is passed through a lens (blue oval) that focuses it on to a beam splitter (grey diagonal line). Some of the laser beams are directed to the sample (bottom right). The fluorescent dyes in the sample are excited by the laser beams and emit fluorescent light. This light passes back through the beam splitter and is collected by a digital camera. Laser beams directed towards the camera are removed by a filter (orange horizontal line).

PHOTO: EAST NEWS/SCIENCE PHOTO LIBRARY Scanning electron microscope (SEM), computer artwork. An SEM uses an electron beam (vertical yellow line) to obtain a three-dimensional image of an object at magnifications much higher than can be obtained using light waves. The beam is scanned over the sample (bottom left) in a vacuum, causing the emission of secondary electrons (diagonal yellow line). These secondary electrons are detected and used to form the image, which is displayed here on a screen.

PHOTO: EAST NEWS/SCIENCE PHOTO LIBRARY Graphene sheets, computer artwork. Graphene a single layer of graphite. It is composed of hexagonally arranged carbon atoms (spheres) linked by strong covalent bonds (rods). Graphene is very strong and flexible. It transports electrons highly efficiently and may one day replace silicon in computer chips and other technology applications. Graphene was discovered by Andre Geim in 2004.

PHOTO: EAST NEWS/SCIENCE PHOTO LIBRARY Bubble universes. Conceptual computer artwork of universes formed from the same Big Bang event. 'Big Bang' describes the expansion (inflation) of all matter from an infinitely compact state at the birth of the universe some 13.7 billion years ago. The inflation theory proposes that during the event, conditions known as a false vacuum produced a rapid expansion at faster than the speed of light. In this, areas of inflation formed 'bubbles' of matter that are completely isolated from each other and evolve independently in parallel to each other.

PHOTO: EAST NEWS/SCIENCE PHOTO LIBRARY Atomic structure. Conceptual computer artwork of electron orbit paths as rings around the central nucleus (yellow) of an atom. This is a classical schematic Bohr model of the atom. In quantum physics, it is thought that the electrons do not actually follow a defined orbit, but instead inhabit areas of probability around the nucleus.

PHOTO: EAST NEWS/SCIENCE PHOTO LIBRARY Nanorobots, computer artwork. Nanotechnology is an area of science concerned with producing mechanical entities on the scale of nanometres (billionths of a metre). It is hoped that robots of this size will one day be used internally for medical applications, such as the removal of cancerous cells, and the plaque that builds up in arteries causing atherosclerosis (heart disease).

PHOTO: EAST NEWS/SCIENCE PHOTO LIBRARY Nanorobots. Computer artwork of nanorobots dispersing from a capsule inside a human body. Nanotechnology is an area of science concerned with producing mechanical entities on the scale of nanometres (billionths of a metre). It is hoped that robots of this size will one day be used internally for medical applications, such as the removal of cancerous cells, and the plaque that builds up in arteries causing atherosclerosis (heart disease). They could theoretically be administered in a similar way to drugs, such as in capsules and tablets.

PHOTO: EAST NEWS/SCIENCE PHOTO LIBRARY Gravitational waves. Computer artwork of a massive object in space, showing gravitational waves as distortions of a grid surrounding it. A gravity wave is a fluctuation in the curvature of space-time which propagates as a wave, travelling outward from the source. Here the grid is used to represent space-time.
