In the above video Brian Anderson of Brigham Young University shows how the acoustic concept of “time reversal” can be used to knock over a series of LEGO figures using sound. The idea is that sound waves are broadcast into an environment and captured by a sensor at a specific location. The signal is then used to work-out how the sound waves bounced about before reaching the location and this information is then used to target that specific location with subsequent sound waves. In the demonstration, sound knocks over 29 LEGO figures one-by-one. It’s very impressive and entertaining as well.

Today is Ada Lovelace Day (ALD), a day to celebrate the achievements of women in science, technology, engineering and maths (STEM). Named after the 19th-century polymath Ada Lovelace, the annual initiative also seeks to engage with the challenges of attracting more women into STEM careers and supporting career development. Now in its eighth year, the day includes a number of events and online activities.
The day will culminate in a few hours with Ada Lovelace Day Live!, a “science cabaret” event at the Institution of Engineering and Technology in London (18:30–21:30, tickets still available). In what promises to be “an entertaining evening of geekery, comedy and music”, the all-female line-up includes several scientists from the physical sciences. Among them is Sheila Kanani, a planetary physicist and science comedian who is the education, outreach and diversity officer for the Royal Astronomical Society in London.
Communicating science through video was the theme of a workshop I participated in yesterday in Hannover, Germany, as part of the Theory and Practice of Digital Libraries conference (TPDL 2016). It was a varied audience that included journalists, academics and librarians. I came away feeling inspired by all the possibilities, but realizing that science communication has a long way to go to use this medium to its full potential. I’ll share with you here some of the key messages.
As Physics World’s multimedia editor, I used my slot to talk about some of the journalistic videos I’ve produced and commissioned during the past few years – discussing what’s worked, what hasn’t and where I think journalistic video production is heading. I made the point that to create engaging web video you have to think carefully about how your audience will be watching the films. Your film may look great on a large monitor, but will it be enjoyed by someone watching it on a smartphone on a bus or train? Also, what are you trying to achieve with the film? Are you trying to entertain or promote something? Or perhaps you are trying to teach? The style and tone will vary depending on the purpose.
