‘Most Trusted’ and NZ Science

The 2014 Reader’s Digest list of New Zealander’s Most Trusted People is out. For scientists, this is a marvellously flawed exercise, but it conveys some nice messages about our society beyond the ivory twittersphere – that is, the strong majority of New Zealanders who have probably never heard of the National Science Challenges or the Marsden Fund. The list is of most immediate interest to scientists because in 2011 we landed a trifecta.

The 2011 list was headed by Sir Ray Avery, fresh from the 2010 award of New Zealander of the Year and release of an autobiography, followed by Sir Peter Gluckman, who had been recently appointed as New Zealand’s first Chief Science Advisor, and the late Sir Paul Callaghan. While refreshing and life-affirming for scientists, this result was unpalatable in wider society because these three gentlemen were, for the most part, unknown to the population at large. The poll methodology was new in 2011, and swiftly changed for 2012. The methodologies are fairly opaque, but it appears that respondents are asked to rate their level of trust in a pre-selected list of 100 prominent New Zealanders. The 2011 poll was weighted towards respondents who actually knew of the person, so Avery, Gluckman and Callaghan were ‘most trusted’ by those who had heard of them. The Herald spluttered, “34% of this year’s respondents decided Sir Ray [Avery]’s ranking, while 97% voted on John Key.” In 2012, a more global average was used, and with Ritchie McCaw coming out on top, no further questions were asked. Our scientists were not the only casualties; someone like Labour Party chief of staff Matt McCarten, 18th in 2011, has been ranked in the 80s ever since.

Two other practising scientists feature since 2011. Exercise physiologist Sir Peter Snell is of course more famous for his athletic exploits, and his appearance on the list in an Olympic year (2012) is no coincidence. But he probably does earn considerable respect from having kicked on to do useful things in later life, perhaps in a similar vein to Sir Ed Hillary. Anthropologist Dame Anne Salmond made a strong entry in the 20s following the award of New Zealander of the Year in 2013, but she is perhaps not so prominent publicly, and her ranking has dropped this year.

Is there a moral to the story? Maybe not. Quite what ‘most trusted’ means is debatable, and fame/celebrity certainly plays a role. It is easy for scientists to either be dismissive of the poll in general, or to embrace the 2011 result as a true reflection of our standing in society, claiming that the changed methodology has made this list a popularity contest. But the ranking surely conveys at least some level of respect, and here’s something to chew on: the top 3 places are occupied by excellent individuals whose main activity involves openly working for and representing other New Zealanders, as part of a unit, community or team. Predominantly, scientists are good people, but that level of unselfishness is rare in our profession, whether forced upon us by structures or otherwise.

Scientists can take heart that individual scientists generally feature in the top half of the poll, and that our position on the equivalent list of most trusted professions is stable, in the range 11-14 (out of 50) for each of the past 4 years. It would be difficult to be dismissive of a significant change in that latter ranking.


My First Publon! On Drop Splashes …

I just created my first Publon! It reviews a paper in which drops are filmed bouncing from surfaces with record-low contact times. For someone whose experience to date consists predominantly of anonymous peer review (both giving and taking) in subscription-model journals, this is a scary step into the unknown! I have chickened out a bit and reviewed a Nature paper that I quite like (so, it’s a good review), but I have tried to point out some limitations of the work.

Publons ambitiously calls itself “The Future of Academic Publishing”. Why not? The general idea is that publishing, review and discussion of scientific literature can take place openly (i.e. not anonymously), encouraging greater transparency and collaboration. Researchers are awarded points on the basis of their contribution, and others’ perceptions of their contribution. It’s taking the open-access publishing movement a couple of steps further; there are obviously practical elements to be sorted out, and the site needs to get a critical mass of users and journals signed up, but the concept is a good one.  Publons participated in the Lightning Lab last year and received some investment as a result.

The founder of Publons is Dr Andrew Preston, who graduated from Vic Uni with a physics PhD in 2010 and spent some time as a Postdoc in the US. Obviously these experiences inspired him to try to do something about academic publishing! He’s an alumnus of The MacDiarmid Institute, a very direct example of one of our graduates contributing to NZ entrepreneurship, and he’s been a good role model for our current students. This one data point suggests that 3 or 4 years post-graduation is realistic to get a startup up and running.

Drops in Space

Two of my favourite fluidics videos are made by Don Petit, a scientist and astronaut who performs experiments on the International Space Station (ISS). I first came across Don at the NZ Institute of Physics meeting in Christchurch (2009) where he wowed the audience with tales of trying to do science in space. Of course, there are many research groups around the world who compete to have experiments performed in orbit, and Don has to execute these, but the experiments in this video were actually carried out in his spare time. They involve waves, bubbles and a chemical reaction in a football-sized sphere of water.

In a more recent experiment, a droplet ‘orbits’ a charged teflon knitting needle. I’ve put ‘orbits’ in inverted commas because an astrophysics colleague reckons the orbit can’t be stable. Is that right? What if the needle was superhydrophobic, so that a drop rebounded elastically from the needle when it came into contact?

The thing about droplets in space is that because there is little gravity, surface tension becomes very important. It’s nice to be able to see surface tension in action so clearly, because it is also important in nanofluidics and microfluidics.

Hello from Geoff W

Hi! I’m Geoff Willmott, newly arrived at the Department of Physics at Auckland. I grew up in Mt Eden, and it’s great to be back home after 15 years based in the UK and Wellington.

My main research interests are nanofluidics, nanomechanics of soft matter, and dynamic microfluidics, which sit within the Condensed Matter research area and involve work within the Department of Chemistry here. I will get some juicy details up on some research pages (under construction!) but in the meantime there will be a blog post or two.

Outside of work I do enjoy a bit of sport, and it’s always a bit of fun in the cross-over … forward pass anyone?
