Nature’s paint palette

I wrote some time ago about structural colour.

More now on that theme.

Some creatures, such as butterflies of the Papilio genus, have sculpted multilayers on their scales: that is they have 2d shapes (for example,like golf balls or dimples) in arrays that maybe interlinked.

Light reflecting off the bottom of the depression (which acts as a 1D structure) is of a different wavelength (and hence colour, say yellow) to that reflecting off the walls (also acting as a 1d structure), say blue. At a far distance the two colours, yellow and blue seem to mix and give the impression that the wings are green!

Another very neat example of structural colour!

Sunday at IEEE Photonics Conference

As I arrived slightly jet lagged and tired for the IEEE Photonics Conference (IPC) I was also a little disgruntled that my favourite shoe shop was far from the hotel.

Not a good start I thought.

But all the cobwebs and irritation was blown away.

The Photonics Pro Training session was mindblowing!

The first talk by Elizabeth Lions on leadership made me ask my self what leadership meant to me, why I or anyone wants to be a leader and how to go about leading. The second talk by Prof. Ben Eggleton carried forward with the theme of leadership and he talked about his career path, the challenges he faced and how he achieved his success.

The IEEE Photonics Society plans to have more such sessions on career development in future conferences to help students and young professionals in the field to gain skills they need to succeed. Judging by the number of people in the room and the age distribution, it seems it is not only young people who want such discussions!

This session was followed by a Women in Photonics panel, where 5 women from diverse research areas, form industry and academia, talked about their career paths. They answered questions from the audience and in a very frank and honest manner gave their take on how to be successful and overcome the challenges they faced. These included hilarious things like a career advisor showing detailed reports to a panelists’s parents on how few women succeed in Science and Engineering to deter her from continuing her studies as an engineer!

Their 5 word advice to young people was:

  • don’t the sweat the small stuff
  • don’t give up
  • follow your passion
  • don’t be hard on yourself
  • believe in yourself

It was interesting that almost all the panelists’s parents had wanted them to be doctors and their choice of Photonics was unexpected to their families.

I am looking forward to Monday now!
