In an episode of the YouTube science series Smarter Every Day, the host Destin demonstrates the unusual behavior of a balloon that’s tied to the floor of an accelerating minivan. It acts in an unintuitive way but this behaviour can actually be explained with physics! Watch the video to learn more.
The Nobel Prize in Physics 2014 was awarded jointly to Isamu Akasaki, Hiroshi Amano and Shuji Nakamura “for the invention of efficient blue light-emitting diodes which has enabled bright and energy-saving white light sources”.

Jennifer Carpenter of Science Careers reports on how journal editors in Science are using social media, in this case Twitter, to reach out to new scientific communities, seek out potential reviewers, and keep up with the latest news in their respective fields. Read her article to hear more about how the Science editors are using Twitter.
On the flip side, NTU researchers can also promote themselves on social media. For example, links of their submitted peer-reviewed articles on DR-NTU are considered open-access so they can freely share them on Facebook, Twitter and other social research sites such as ResearchGate or Academia.edu.

Is theoretical physicist Ed Witten more influential in his field than the biologist Solomon Snyder is among life scientists? And how do their records of scholarly impact measure up against those of past greats such as Karl Marx among historians and economists, or Sigmund Freud among psychologists?
Due to the differences in the performance metrics between the different fields in the sciences, it’s hard to determine whether a scientist from say, chemistry, is more influential than another one from biology. Citation counts also vary wildly from one discipline to another. But researchers at Indiana University Bloomington believe they’ve worked out a system that equalises the playing field based on dividing a researcher’s h-index by the average of their field.
Scientific American’s article goes into greater detail regarding this controversial topic.

Andrew Jones on About.com Physics talks about Mario Livio’s book:
A recent book by astrophysicist Mario Livio, Brilliant Blunders: From Darwin to Einstein, focuses on five of the greatest scientific blunders of the last two centuries. What’s really interesting to me about the book is that he selects five blunders that are instrumental to our modern understanding of how we came to exist
