Fermilab’s Don Lincoln is back with yet another entertaining video, this time about what people get wrong about time dilation. In particular, he asks whether the famous “twin paradox” is actually paradoxical. You can watch the video above, enjoy.

Have you taken a stunning photograph of the sky lately? If so, you still have a week to enter the Insight Astronomy Photographer of the Year, which is run by the Royal Observatory at Greenwich and sponsored by Insight Investment. This is the tenth year of the competition and to celebrate, the 2018 winners will have their work displayed at a new gallery at the National Maritime Museum in Greenwich – which will also show some of the best images from past contests.

Triumph of alliteration

Finally, in a triumph of alliteration there is a paper on the science of science in Science. According to the authors, he science of science (or SciSci) is “a transdisciplinary approach that uses large data sets to study the mechanisms underlying the doing of science – from the choice of a research problem to career trajectories and progress within a field”.

Among other things, the paper analyses the publication record of three physics Nobel laureates. This shows that these leading physicists have published high-quality work throughout their careers – and not just at moments of prize-winning brilliance.

Another interesting plot in the paper shows that the average number of authors on science and engineering papers has increased from just a shade more than one in 1900 to nearly five today. What’s more, today the average number of authors on papers judged to be of high quality is six – suggesting that bigger research collaborations may be better.
