ateneophysicsnews_motoi_wada_20160708 (2)

The Department of Physics of Ateneo de Manila University cordially invites you to a talk entitled, Art of Science and Engineering II, by Prof. Motoi Wada of the Applied Physics Laboratory of Doshisha University. The talk will be held on July 14, 2016, Thursday, 10:00 a.m., at the 5th floor of the Rizal Library. Light snacks will be served.

This talk is Prof. Motoi Wada’s second talk at Ateneo de Manila University upon the invitation of Dr. Christian Mahinay, Head of the Vacuum Coating Laboratory of the Department of Physics. Prof. Wada’s previous talk was entitled, Art of Science and Technology, which was held last November 27, 2015, 1:30-2:30 p.m. at the Social Science Lecture Rooms 3 and 4He talked then about  Japan’s research in the fields particle accelerator physics and semiconductor industry–all with references to art and history.

Now, in Art of Science and Engineering II, Prof. Motoi Wada shall dazzle us once again with his breathtaking slides and videos as he talks on the latest updates on the LIGO experiment for gravitational wave detection and the engineering precision required to make such detection possible in Astronomy. Prof. Wada shall also talk about the cosmic recycling process–about how some stars die a violent death as supernovas, and how the dust and fragments from the nebulous smoke pull themselves together again through the force of gravity, forcing hydrogen atoms to combine to form Helium, resulting in nuclear fusion reaction that gives birth to new stars. But on Earth, the Hydrogen atoms that we generate do not have enough cumulative mass to form a star through nuclear fusion. So the only way perhaps is to force the fusion of Hydrogen by some other means aside from gravity, as Dr. Otto Octavius (Dr. Octopus) tried to do through the magnetic fields from his tentacles, before he plunged into the depths of the sea, holding the newborn star that could have destroyed the human race.

Is man-made nuclear fusion already possible with today’s technology?  How far are we before we can ditch fossil fuel, such as coal and crude oil, in favor of clean energies like nuclear fusion? Let’s ask Pro. Motoi Wada when we attend his talk on ARt of Science and Technology II this July 14, 2016. See you there!

Volume holographic generation of optical Bessel Beams: a physics dissertation defense of Jonathan Manigo on 19 Apr 2016



The Department of Physics of Ateneo de Manila University cordially invites you to a Physics Dissertation Defense:

Ph.D. in Physics student name: Jonathan Manigo

Dissertation title: VOLUME HOLOGRAPHIC GENERATION OF OPTICAL BOTTLE BEAMS Schedule and venue: April 19, 4 PM at SECB 201.

Dissertation Adviser:

  • Dr. Raphael A. Guerrero

Dissertation Panel:

  •  Dr. Nathaniel Hermosa II (NIP-UPD), Dissertation Examiner
  • Dr. Nathaniel Joseph Libatique (ECCE), Dissertation Examiner
  • Dr. Ma. Obiminda Cambaliza (Physics), Dissertation Reader
  • Dr. Quirino Sugon, Jr. (Physics), Dissertation Reader


Abstract. Self-imaging beams consisting of three-dimensional intensity voids are generated via photorefractive volume holography. Reconstruction of a volume hologram recorded at 594 nm is performed with a Bessel read-out beam. The holographic output is similar in appearance to a Bessel beam, with the central spot oscillating between maximum and zero intensity over a propagation distance of 10 to 55 cm. The oscillation period for the on-axis intensity is 30 cm. The reconstruction is capable of self-healing, with a fully recovered central core after the beam propagates 40 cm. Dual-wavelength reconstruction at 632.8 nm produces an output beam with similar self-imaging and self-healing properties. A theoretical framework based on the interference of a plane wave and a Bessel beam simultaneously reconstructed from a volume hologram is able to describe our experimental results.

IBM Research Scientist Dr. Paulito Palmes to give a talk on Deep Learning


Paulito Palmes to give a talk on “Deep Learning: Overview and Applications” on jan 21, 2015, 4:30 p.m., at CTC-313.

The School of Science and Engineering, Ateneo de Manila University and Ateneo Social Computing Science Laboratory cordially invites you to attend the 2016 SOSE Lecture Series featuring “Deep Learning Overview and Applications” by Paulito P. Palmes, Research Scientist at IBM Ireland’s Dublin Research Laboratory (DRL) and Balik Scientist on January 21, 2015, 4:30pm-6:00 p.m. at CTC313


Big companies such as Google (DeepMind, Google Brain, Google Photos), IBM (Watson), Microsoft (Skype translator, Cortana), Facebook (DeepFace, FAIR), and Baidu (DeepSpeech) are investing heavily on deep learning technologies for their cognitive computing applications. Information is continuously growing and a big chunk of this Big Data is unstructured information. All these companies are involved with Big Data processing and are confronted with the problem of how to automatically extract relevant information for monetization. Deep learning, which is a reincarnation of Neural Networks with much deeper processing layers, has been shown to be effective in extracting features and abstractions automatically for large scale unlabeled data. It is a generic algorithm which can be applied to image recognition, natural language or speech processing, and prediction. In deep learning, the bigger and deeper the network is, the more accurate and robust is its performance. Due to its highly computer-intensive requirements, most implementations use GPUs to speed-up training specially for very deep networks. There are two parts in the presentation. The first part is for the general audience. It starts with some background information and historical development of Neural Networks and its recent reincarnation. Some basic concepts on how the network learns patterns and the underlying mechanisms how it generalises will be discussed. The second part is intended to those who would like to see real applications and sample codes. A brief overview of Julia programming language will be covered followed by its application to image recognition using its Deep Learning module.

During the 50th Anniversary celebration of the Department of Physics last October 10, 2015, one of the alumni who shared her memories of the department is Genevieve Rose H. Lorenzo. She finished her BS Physics in 1998 and her MS in Electronics Engineering in 2010–both from Ateneo de Manila University. Since 2002, Genie has worked as a research staff in the Urban Air Quality Dynamics/Instrumentation Technology program of Manila Observatory.

One of Genie’s tasks at Manila Observatory is maintenance of MO’s 42 Automated Weather Stations: 28 in Metro Manila, 8 in Rizal,  1 in Cavite, and 5 in Mindanao. An Automated Weather Station automatically measures rainfall rate, accumulated rainfall, temperature, wind direction, and air pressure–something similar to Fr. Angelo’s Secchi, SJ’s Universal Meteorograph in 1867 which Manila Observatory acquired during its foundation at the time of Fr. Federico Faura, SJ.  The only difference is that the data are not anymore recorded by pen on paper but electronically and transmitted to Manila Observatory via the Internet. Genie writes scripts in Python or PHP to format the data from the automated weather stations to serve as input for forecasting typhoon tracks and rain volume and also for modeling climate change risks. Many of the weather reports published by the observatory were co-authored by Genie.

Genie’s other task at Manila Observatory is maintenance of air samplers used for air quality research. These machines suck in air and let them pass through a filter. The filter is then weighed and chemically analyzed in MO’s UAQ/ITD lab to determine whether the soot comes from cars, industrial exhausts, etc. The difference in the blackness of the filters can be considerable, e.g. comparing the air in EDSA with that of Antipolo. Genie also joins in the Manila Observatory’s annual air quality monitoring during New Year’s Eve. An example of this is the Urban Air Quality Report of 2014.

Below is a copy of the speech of Ms. Genie Lorenzo during the 50th Anniversary celebration of the Department of Physics.


by Genie Lorenzo

In 1986 Halley’s Comet was in the sky, and somehow my papa and I were able to watch that together.  That was maybe my first stark memory of being amazed by the night sky.  Then in high school I was intrigued by the metric system, how a camera worked, and an experiment in physics class with candles and lenses and inverted images, and my high school Physics teacher, Ms. Alcid, was so clear and coherent with her lessons that I, perhaps without knowing any better, bravely ticked the BS Physics CE program in my college entrance application to the Ateneo.  My neighbor Thryza kept on convincing me to go to the Ateneo, where she too was enrolled, and so when I found out that my good friend from high school, Anne, was going to Ateneo to enroll in the undergraduate double degree Physics and Computer Engineering program, I decided to come to Ateneo and enroll in that program too in 1994.  (Eventually I finished only the BS Physics program, and pursued the MS Electronics Engineering degree later.)

A. Demonstrations

I remember it must have been the first day of our freshman Physics 31 class or lab, and our teacher, Dr. Simpas (he must have been in his early thirties then) had me stand on a measured particular spot in the room,  while he swung a metal ball tied to a string toward me in order to demonstrate the pendulum.   There was also a spring demonstration shown to us during our tour in Faura Hall in freshman year, among other things there like the “resonance” demonstration.  For me the spring set-up in Faura merely looked like a slinky that one found in toy stores on display, and like many of the concepts taught in class, I think they call people like me a slow learner, it took me a while to appreciate why that spring, waves, and sine waves were so important and fundamental in our everyday lives and the universe.  Most of the demonstration set-ups then, they say, were made by Mr. Tecson, so our block was both very excited and a bit worried to have Mr. Tecson as our first EM teacher as we heard about his unique, effective and yet frightening style of teaching and giving oral exams for each class meeting.  We began some classes with Mr. Tecson, but then he got sick, and so he couldn’t be our teacher, and then some semesters after he was again supposedly going to be our teacher, but then he passed on.  Then there was Mr. Montuno, and the Millikan Oil Drop experiment in the Advanced Physics lab, and oral exams about the Twin Paradox.  And so for my 18th birthday by blockmates gave me a white puppy, whom we named Tipler, after the author of the Modern Physics book that guided us through countless overnight review and problem set solving sessions.

B. Manila Observatory

For senior year, I signed up for thesis work at the Manila Observatory, which for us then, maybe until now (?),  was a relatively unknown faraway location on campus.  I do not remember now if it was before or after the thesis but at some point after I had trekked over to that part of campus I was able to pay a visit to Fr.Dan in his brown room (the furniture was all brown, and ancient, and he had so many books that must have been classics on the bookshelf) and when I asked him what I could do there, he simply replied, “water vapor.”  “It is important to study water vapor especially here in the tropics,” was what he said. The topic assigned to me for my thesis was on clouds and optical depth, and Dr. Alarcon was my adviser and we communicated via email as she was sent to Rose-Hulman in the US then.  And I don’t think I did much… but Dr. Alarcon was gracious to me and, maybe because of her absence, she took it easy on me, but I remember being so amazed and engaged by the new things I was reading about on clouds and radiation in the journals.  And there was no google then, only the beginnings of alta vista search, so we had to manually look through all the journals, and even visit the PAGASA library in Quezon Avenue, and correspond with the authors of the journals via email and await the copy via snail mail— and to open an envelope with a journal from an author for me then was already a big thing.

C. Personal Care

Mr. Bennett was our teacher too and our friend, once after college I was recounting to him the story of how I  found myself somehow in the UP NIP laboratories looking for a research assistantship.  I told him how there seemed to be no other openings except in the Theory Department, and how I had knocked on their door and met some people, and asked them if I could work there, and after which they asked me which problem of those posted on the wall I knew something about, to which I honestly answered, none but I that I was willing to learn.  And then one of them at the Theory Lab, a tall guy, asked me if I knew the story of Alice in Wonderland?  Let me lift a line from the text of Lewis Carroll from which the tall guy drew his conversation piece, “One day Alice came to a fork in the road and saw a Cheshire cat in a tree. ‘Which road do I take?’ she asked. ‘Where do you want to go?’ was his response. ‘I don’t know,’ Alice answered. ‘Then,’ said the cat, ‘it doesn’t matter.”  That tall guy left me then, and they gave me an email address to contact, I think it was Perry Esguerra’s email address.   And Mr. Bennett has asked me, in our a few short but always memorable chance encounters, so where are you going?  And for that I am grateful.

Somehow I found myself back at the Manila Observatory in 2002, and have been in the institution doing a variety of things from air sampling, to weather monitoring to stargazing since then.  In 2012, because the Manila Observatory is interested in science that will help ease the suffering of our people, I was able to visit a town in Davao Oriental, devastated by the Typhoon Pablo.

There I was able to witness the human spirit that prevails and that is sustained in the worst of circumstances.  And there the WHY of our workings, and on a personal note– everything that I had been through and that led me to that point… became clear.

D. Humility

What has being a Physics student- which I think I am for life, I am a Physics student for life–what has it taught me?

I am gratefully, joyfully, gracefully, blessedly humbled by all the learnings that being a Physics student has taught me.  And I think it is through this humility that I was led to wonder (through childhood experiences with nature and the Physics Demonstrations), meaning (through my personal search, and the Manila Observatory), and connectedness (through God’s graces, and Personal Care), even with my own inadequacies, doubts, and failures, so that I could be of some use and help to others.

My father often asks me, because he knows how much difficulty I have had with academics and all, what is it exactly that I do.   I try to describe it to him the air samplers, and the weather stations and the data we have and the maps we make at the Manila Observatory whenever there is an impending storm, but am not sure he understands exactly.  Little does he know how much an effect that one evening, we spent together under the night sky many years ago, had on me.

We are now with some of your MS Atmospheric Science Graduate students and BS Physics Undergraduate students working on the data of the weather stations which we have set up around Metro Manila.  It makes me excited because we have never actually studied our local weather as in depth as we are doing now, and I am also at the time same nervous because our work is also a responsibility and so we have to be thorough because there are many who will be affected by our findings.

E. Congratulations

Congratulations to the Physics Department on its 50 years. Thank you for of introducing us to the wonders and rhythms of everyday life in the classroom and in the laboratory, for leading me and others to our working institutions like the Manila Observatory, and for your personal care and concern for us students.  May you continue to mold students to become the best that they can be through their science in order that they can continue to be of service to others.

This 50th year celebration is also in tune with the global celebration of 100 years of the Einstein’s Theory of Relativity this year, and 150 years, also this year, of the Manila Observatory, from where the department traces its roots, and after whose first director, Padre Federico Faura, SJ, the building which houses the Physics department on Campus was named.

F. Prayer

What about that Cheshire Cat and the fork in the road, what do I say when he asks again, what do you want?  I respond in prayer:

Direct, we beseech Thee, O Lord, our actions by Thy holy inspirations and carry them on by Thy gracious assistance; that every word and work of ours may always begin from Thee, and by Thee be happily ended, through Christ our Lord. AMEN
