The International Day of Light brings together culture and science.
 — SPIE John Dudley, Steering Committee Chair of IDL

This phrase was part of the message given by John Dudley during the introduction to the International Day of Light 2019 at the International Centre for Theoretical Physics (ICTP) in Trieste, Italy. And it reflects the importance of bringing together the science, technology, culture, and art that involves light in this emblematic celebration.

This year, the IDL celebration was about “Illuminating Education,” and for the event participants, we enjoyed talks about science outreach, development, art, and education that reflect the diversity of projects done to improve the world where we live using optics and photonics.

The official program began with a keynote presentation that explains light phenomena at four levels: rays, waves, polarization, and quantum, where Sir Michael Berry, University of Bristol and ICTP Distinguished Lecturer, showed us how to engage a wide audience using pictures to explain light.

From the National Optical Astronomy Observatory, Stephen Pompea spoke about outreach and how to communicate about light. He explained that setting engagement as the goal of an event rather than outreach shifts the focus to the audience, because engagement is based on participation from your audience and not on the people organizing the event. Rachel Won, international editor of Nature Photonics, also spoke about science communication, explaining that as a science editor, you become an ambassador of science. Finally, Federica Beduini, outreach and science communicator at ICFO recommended we “act locally and think globally” when conducting outreach projects.

After lunch, we had the opportunity to hear about the diverse challenges facing science and education. The first presenter was Krisinda Plenkovich, director for education and community services at SPIE, who explained how photonics is used to achieve some of the Sustainable Development Goals of the United Nations. During the second talk, Brian Liebe, director of standards and research for the Illuminating Engineering Society, discussed that everything—every career path—is touched by light, and we need to pull together science, engineering, and art.

Later, John O’Hagan, director of Division 6 “Photobiology and Photochemistry” of the International Commission on Illumination, described the importance of public awareness and education around lighting quality. He challenged us to take common sense into account when we are thinking about how to implement new technology, looking for the better solution. For the final presentation of the session, Prajna Khanna, head of corporate social responsibility and director at Signify Foundation, talked about her organization and remarked on the importance of adapting the technology to the reality of each environment.

The second keynote talk was about development challenges, specifically, how we can use physics to feed the planet, presented by Cather Simpson. Simpson, who won the third place in the 2018 SPIE Startup Challenge, is a professor of physics and chemical sciences at the University of Auckland where she also started the Photon Factory. She explained different projects that use photonics to feed the people, such as vertical farms, harvesting the sun, and improving milk production. She gave inspirational examples about how to use light science and technology to improve our lives and make the world a better place for everyone.

For the artistic segment of the event, John Taylor, director of the Executive Office at The Optical Society, presented a documentary about an art installation in Washington DC to celebrate IDL 2019 and award-winning photographer Saurabh Narang explained some of his most amazing photographs.

For the third segment of the event, we heard Jess Wade, postdoctoral physicist at Imperial College London and gender equity advocate, talk about diversity, equity, and inclusion. Jess was so inspiring because she demonstrated how something that can look so simple, like a Wikipedia article, could drive change and make a big impact in the world.

Amna Abdalla Mohammed Khalid discussed the aims and objectives of her organization, the Next Einstein Forum, and the positive impact that it is having in Africa by creating a unified scientific identity that fosters innovation and discovery.

For the last session, students and early careers representatives from international scientific societies, like myself, described the work each of them is doing as a volunteer with their organization to promote photonics and IDL. Roberta Caruso talked about the Young Mind project of the European Physics Society. Ezabo Baron and Kithinji Muriungi from the IEEE Photonics Society presented on the outreach programs they are doing in Africa. Duarte Graça and Artemis Tsimperi from the International Association of Physics Students described the great work performed by this society, work done by physics students for students. Xiang “Dino” Dai talked about the work of his OSA student chapter and encouraged everybody to try to inspire kids to learn about optics, photonics, and light.

The last presentation was mine, and I presented some of the optics projects and programs that I had participated in—thanks to the support of the SPIE—including Optics for Everyone and its adaptation to Spanish, and the Mexican curricula for the Dumpster Optics workshop. Finally, all the students presented our opinions about our careers and the importance of doing photonics outreach work, including global initiatives like IDL.

The entire day and celebration was an inspiring event where experts from all over the world explained their work and their projects. I’m very sure that all the people that were present learned something new. And importantly, they were inspired by the amazing work performed by all the presenters to advance light and its impact.

#FacesofPhotonics: NASA Intern Elaine Stewart

MIRROR, MIRROR: Elaine with the JWST at Goddard Space  Flight Center in Greenbelt, Maryland Meet Elaine Stewart: chemical engineering student, world-traveler, intern at NASA's Goddard Space Flight Center, and this week's SPIE Face of Photonics. Elaine is fascinated by space exploration and how optics impacts our ability to "study distant stars that have never been seen before." Her research has taken her around the world -- from Bochum, Germany, where she studied material science and engineering at Ruhr-Universität, to Houston, Texas, to work on the James Webb Space Telescope (JWST) while it was under cryogenic vacuum chamber testing, to Melbourne, Australia, where she studied biochemical and product engineering at the University of Melbourne in 2017. And, when she's not busy traversing the globe, she is focusing on graduating from the University of Delaware in 2019 with a Bachelor's in Chemical Engineering. Elaine makes a point of remaining an active

Cataract surgery: misnomer?

On left, the patient’s left eye has no cataract and all structures are visible. On right, retinal image from fundus camera confirms the presence of a cataract. (From Choi, Hjelmstad, Taibl, and Sayegh, SPIE Proc. 85671Y , 2013)   Article by guest blogger Roger S. Reiss , SPIE Fellow and recipient of the 2000 SPIE President's Award. Reiss was the original Ad Hoc Chair of SPIE Optomechanical Working Group. He manages the LinkedIn Group “ Photonic Engineering and Photonic Instruments .” The human eye and its interface with the human brain fit the definition of an "instrument system."   The human eye by itself is also an instrument by definition. After the invention of the microscope and the telescope, the human eye was the first and only detector for hundreds of years, only to be supplemented and in most cases supplanted by an electro-optical detector of various configurations. The evolution of the eye has been and still is a mystery.   In National Geogr
