You can help paint a fuller picture of the physical sciences community. AIP collects and preserves visual documentation of the personal and professional lives of physical scientists. Our archive of photos, and the stories behind them, is widely used by members of the physical science community, historians and researchers.
Pictures of scientists play an important role in shaping ideas about what kinds of people practice science and what kinds of activities scientists engage in, so it is critical we have access to rich and diverse visual documentation of both who practices science and the full lives science professionals lead.
Each month we’ll feature a recent contributor to our archive and share their images and story. Thanks to a generous grant from the Henry Luce Foundation, AIP will highlight women’s contributions to the physical sciences as well.

Science is Teamwork
“The work represented in this image is not just about an instrument. It is about decades of discovery, collaboration, creativity, and people working together to make measurements more reliable for everyone.”
Haddad received her Ph.D. in Optics, Optoelectronics and Microwaves in 2004 from the University of Versailles, France, where she continued teaching and doing research in the field of optical sensors and dimensional metrology. In 2006 she worked on precision experiments to measure the Planck constant, first as a Post-Doctoral Fellow at the Laboratoire National de Métrologie et d’Essais (LNE), France, and since 2008 at the National Institute of Standards and Technology, USA.
“Science may look hard, and it is, but it is also deeply fun. I get to learn something new every day, solve new challenges, and know that the work is helping advance science and technology.”
Darine Haddad is currently the project lead at NIST for the US primary realization of the unit of mass (named NIST-4), and the Quantum Electro-Mechanical Metrology Suite (QEMMS), featuring the compensation of gravitational forces with the use of two quantum electrical standards, bridging classical mechanics with quantum mechanics in a single experiment.

Dr. Gemma Rius, tenured Research Scientist at the Institute of Microelectronics of Barcelona (Catalonia, Spain), presents on the research and development activities of the Institute of Micro and Nanoelectronics to a group of young students. This outreach activity was the first guided tour to a research institute in Catalan Sign Language. It was part of a Science Communication activity within a project funded by the FCRI (Catalan Foundation for Research and Innovation) on STEM for people with hearing impairments.

Digital photography has transformed how we record our lives and connect with each other. At the same time, the people and roles that make up the physical sciences have changed considerably.
We can no longer wait until people retire and hope their photographs eventually make their way into our collections. We need to connect with scientists throughout their careers and be part of how they document their lives and work, so the record we preserve reflects the physical sciences as they are today.
