“Diamond Graph” Corrects Long-Standing Errors of 3-D Bar Graphs
Example of New Diamond Graph
Looks can be deceiving. That’s one of the problems with today’s three-dimensional bar graph. While these graphs may look correct, researchers from the Johns Hopkins Bloomberg School of Public Health believe they are in fact inaccurate and misleading.
Currently, the 3-D bar graph is used in countless computer programs, scientific journals, and newspapers to display financial, medical, and other information in which two variables lead to an outcome. Alvaro Muñoz, PhD, a professor of epidemiology at the School of Public Health, has developed the new Diamond Graph, which corrects these errors and represents all the variables equally in a form that is easy to read. He believes the new graphing method could replace the traditional 3-D bar graph in software commonly used in business and science. Dr. Muñoz and his colleagues described the Diamond Graph method in an article published in the August 2003 edition of the peer-reviewed journal, The American Statistician.

Physicists have developed a technique based on optical microscopy that can be used to create images of atoms on the nanoscale. In particular, the new method allows the imaging of quantum dots in a semiconductor chip. Together with colleagues from the University of Bochum, scientists from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute reported the findings in the journal Nature Photonics.
Microscopes allow us to see structures that are otherwise invisible to the human eye. However, conventional optical microscopes cannot be used to image...
On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.
We carry smartphones in our pockets, the streets are dotted with semi-autonomous cars, but in the research laboratory experiments are still being designed by...

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
