IOSA @ CEIP Antonio de Nebrija

Last week IOSA visited CEIP Antonio de Nebrija, in Alcalá de Henares. We bring different workshops for students aged from 10 to 11 years old. They learnt about the difference between phosphorescence and fluorescence, about why objects have different colors and about the kind of lenses there are and how we can use them to correct visual problems. Everybody could touch and experiment with all workshops, so they really enjoy them!

We also elaborate a survey in order to know which one is their favorite workshop or the most difficult one. In this way, we also learnt about how to improve our workshops.

Following you can see some photos we took:

Prof. Ursula Keller visits us for the IOSA Scientific Seminars!

Last December we were pleased to host Prof. Ursula Keller’s at the IO-CSIC Student Chapter. The day started with lab visits, to show her the research being carried out at the Institute of Optics (IO-CSIC). Then, at the conference room, Prof. Keller gave her talk, titled Attosecond Ionization Dynamics and Time Delays. It was a very interesting look over quantum mechanics progress and the research done in her lab related to this topic. The audience, which included researchers from IO-CSIC as well as from other universities and institutes, was lively and showed their interest in the topic by asking many questions at the end.

Prof. Keller’s lecture was the kickoff to our IOSA Scientific Seminars. These one-day Seminars consist on short talks given by the researchers (pre-doc, post-doc, and tenured researchers) of the Institute, and the goal is for researchers to explain their current work in a lively, concise manner. These talks followed Prof. Keller’s talk and a coffee break intermission. They were a nice overview of the research that is being carried out at the IO-CSIC. Many questions from the audience came up as well.

Before having lunch, we gave Prof. Keller a short tour around our campus and talked about its history. She was quite excited to learn more about Spain’s history and culture, which she already had an affinity for.

Afterwards, the Student Chapter as well as our advisor, Prof. Susana Marcos, had lunch with Prof. Keller, and had the opportunity to talk to her about women in science and share different points of view. Ursula Keller was positively surprised by the high amount of female scientists that there are in our Student Chapter. We gave her some presents as souvenirs of her visit to our Chapter.

After lunch, we showed Prof. Keller another lab. This was the end of the “official” visit. Then, she invited us to have a drink in a bar. Besides her incredible resume, Ursula is a very approachable, kind and straightforward person and told us about her background and how she worked to get her current position. She also asked us about our career expectations and gave us very valuable advice.

Prof. Ursula Keller’s visit was great and we thank her for finding a spot in her tight schedule to visit us. We’d also like to thank the OSA Traveling Lecturer Program for giving us the opportunity to invite Ursula Keller and being always so helpful with our inquiries.

4th edition of the IOSA Scientific Seminars

On December 14th the 4th edition of the IOSA scientific seminars will take place. As in the last years, these seminars are open to all the staff of the Institute of Optics: pre- and post-doctoral researchers, technicians, as well as senior researchers, and, of course, all the IOSA members or IO members. The aim is presenting the different lines of research developed in the Institute and promoting discussion between the different groups. Moreover this year, thanks to the OSA Travelling Lecturer Program, we are delighted to inform you that we will count on the presence of a renowned speaker, Prof. Ursula Keller, from ETH Zurich (Switzerland), who will give a seminar on “Attosecond Ionization Dynamics and Time Delays”.

Save the date:

14th December 2017 at 10:30am
Salón de Actos IQFR-CSIC

Abstract of Prof. Ursula Keller’s talk:

The basic motivation is to understand and ultimately control how matter functions at the electronic, atomic and molecular level. Initially our focus is on the question how quanta of energy and charge are transported on an atomic spatial and attosecond time scale. In principle, time dependent-processes in quantum mechanics are described by the time-dependent Schrödinger Equation (TDSE). The challenge is that the TDSE in most cases cannot be solved without approximations and that time is not an operator and therefore not a direct observable. This talk will review the recent progress in attosecond ionization dynamics and time delays in photoemission and tunnel ionization. Following the peak of an electron wavepacket for determining time delays can be tricky and often misleading.

See you at the Seminars!!

Week of Science 2017 – Understanding the reality beyond perception

As a part of Week of Science, conducted in collaboration with Community of Madrid and IOSA student chapter, students and families from Madrid participated in workshops aimed at introducing the magical world of optics to the younger generation.

It is something that surrounds you, some of which you can’t even see, touch or feel, yet something that you use everyday and depend on it: The Electromagnetic radiation. Thus we came up with the theme of this time’s exhibition as “A journey through Electromagnetic Spectrum”. Workshops were focused on explaining and demonstrating different regions (visible and non-visible) of electromagnetic spectrum in an experimentally oriented, fun and interesting ways. Laser maze and Passport to all the participants with cool pictures and interactive activities added colour to the whole event.

Missed this year’s week of science workshops? Don’t worry. Stay tuned and save the date for next year.

Here are some of the highlights of this year’s Week of Science optics exhibition.

IOSA brings Light to Medina del Campo

Last month we went to Medina del Campo as a Ciudad Ciencia activity. It was the patron saint festivities, San Antolín, and our workshop Discovering Light was part of the celebration schedule. We carried out the workshops Human vision, Ray tracing, Fluorescence and Optical fibers. The audience that attended were mostly children and they were very interested and very surprised with the workshops we showed them. They were very participative and looking forward to repeating next time.

The previous day (4th of September 2017), Onda Cero Medina del Campo interviewd us in order to promote the activity among Medina’s inhabitants!

An advance on the phenomenon that made us win a Poster-Comic Competition…….

Surely you’ve seen this phenomenon in nature a spring or summer day. Now you know how it’s called……

Soon more post of this topic…….

IONS Paris 2017

IONS Paris Conference took place between the 14th and 17th of June, and three of our Chapter members attended with really good feelings. Their contributions were two talks and one poster. Also, they represented the Chapter doing some workshops for children.

Part of the conference happened at École Polytechnique, which is in a peaceful environment surrounded by vegetation. This place is full of instruments that belonged to important figures of the history of Physics and Optics such as Hermann von Helmholtz or Augustin Fresnel.

Our first experience before arriving at the University was very tiring, after climbing never ending stairs. But the fatigue did not last long, remembering that we were in Paris, and seeing the diversity of students from different countries that were there, and that we had to meet.

Arriving to the École Polytechnique the first day of the IONS Paris 2017

Clara Benedi-Garcia talked about the impact of the interactions between mono- and chromatic aberrations on visual function on the first day.

During the congress there were many keynote speakers and interesting talks/posters from other students. One of them was Prof. Viktor Gruev, whose talk named “Bio-Inspired Sensors: From the Ocean to the Operating Room” will help our chapter to improve our workshop about animal’s vision. On the other hand, Prof. John Dudley with his talk about “Solitons to supercontinuum – the science and applications of nonlinear fiber optics” and Dr. Carsten Baur, talking about “Solar cells for space applications: challenges and opportunities” inspired us also new ideas to our workshops.

The last day of the congress, some student chapters carried out some workshops for children. Our chapter did the “Communication with light” and “Phosphorescence and fluorescence” workshops thanks to the help of a French researcher, Mathias Berciano, who did the translations from English to French. This experience was really gratifying, because we could know how French schools are and also our translator, Mathias, learnt from our workshops. As the organization of the Congress said, the language is not a barrier to discuss science.

Outreach activity

After doing the outreach activity, our chapter could join the other chapters from Russia, Italy and Colombia and share the workshops we do, so there was a great exchange of ideas.

There were also some posters from other student chapters, where we could learn which kind of activities they do in Barcelona, Naples, Russia or Southampton. We talked a lot with all of them during the poster session and after, discussing about our ideas and projects. Social networking was very useful for everybody, because at the end of the day, all of us have the same goal: to divulge science to the society.

To encourage this social network, many activities besides academic presentations were organized like wine tasting or gala dinner.

Gala dinner was placed on ‘La Maison des Polytechniciens’, a beautiful and very luxurious place where we could enjoy a pleasant atmosphere. It was an unforgettable experience.

Networking during the Gala Dinner

After the three-day congress, there was a Social Day and our members joined it! It was a great way to know the heart of Paris, with a river cruise on the Seine, a picnic at the “Champ the Mars” and guided walking tour of the “Ile de la Cité”. It was also a good way to get to know better the others congress assistants, ask more questions about their work or their chapters, etc.

Itinerary of activities during the Social Day

In summary, it was an unforgettable experience for our members, they came with a lot of ideas, proposals for the Chapter, new contacts and good memories!
