A picture paints more than a petabyte of data
In the age of the petabyte, we all need help digesting and understanding massive amounts of information. In this month’s Physics World, a series of features celebrates the ascendance of visual methods that are being used to make meaning of the mountains of scientific data.
Scientific visualizations can play a key role in fundamental physics, particularly when it comes to depicting the outcome of particle collisions at CERN’s massive new Large Hadron Collider, but they can also shed light on much more everyday research.
A feature written by Cesar A Hidalgo, a physicist at the Centre for International Development, Harvard University, US, explains why ‘network science’ could be a useful tool in both national economic planning and in medical research.
In medical research, a database of medical records from a large population of elderly US citizens has been used to build a ‘disease network’ to show how various disease associations are distributed and, among other things, alert doctors to health risks closely associated to any particular ailment.
A similar project, called the Product Space produced in collaboration with a team of economists, maps out the kind of tradeable products that tend to emerge together in national economies and highlights areas where economies may have great difficulty diversifying.
On providing easily understandable information that deals with very complex subjects, Barry Sanders, iCORE chair of quantum information science and director of the Institute for Quantum Information Science at the University of Calgary, Canada, writes about the work he has undertaken with a team of researchers and animators to produce a “movie” that explains how quantum computers work, Solid state quantum computer in silicon.
Acknowledging the need to delicately balance scientific accuracy and aesthetic appeal, Sanders writes, “Visualization of scientific knowledge is not easy or cheap, but it is rewarding and useful. Animated films are valuable tools for explaining difficult, abstract concepts such as quantum computing in the classroom.”

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
