Here are collected pictures from the vendor exhibition at the SPIE Optics+Photonics 2019 conference in San Diego, CA.
I always find these exhibitions strangely fascinating, and I wanted to capture why. Enjoy!
The publication has a tremendous legacy, with writers such as Hannah Arendt (who published her series on the banality of evil there), James Baldwin who covered the civil rights movement and Susan Sontag who mused on various topics (see her collected articles in Against Interpretation and On Photography.)
I am speaking as a member of a certain democracy and a very complex country that insists on being very narrow-minded. Simplicity is taken to be a great American virtue along with sincerity. One of the results of this is that immaturity is taken to be a great virtue, too. – James Baldwin
Wow the levy is about to break on Open Access!here, and here), and things have been changing at an incredible pace.A quick explanation about the topic: scientists share their research by publishing into very specialized journals. These journals then either charge a fee (>$10) for any reader to read a specific article, or as is more often the case, collect a subscription for an institution so that all of the people who work for this institution get complete access to a journal or a set of journal. The problem here is that the research submitted by the authors is often funded by public entities, which do not have the right to read the publications of other group freely (open access.) And the subscription fees have skyrocketed (e.g. in the order of $10 million for UC Berkeley.)But now, large entities are rebelling.The first salvo came from funding agencies, which require the papers to be made freely available, either by sharing the pre-prints (e.g. on arxiv) or by publishing in an Open Access journal (journals where the authors pay (usually $1000!) to get published, and where anyone can read.)Then came Germany, which reached an impass with the academic publisher Elsevier (one of the leading actors, together with Springer and Wiley) and decided not to pay for the racket (projekt DEAL). The issue has not been resolved yet and German researchers still do not have access to publications such as Cell (they can however directly contact the authors of the papers to get the papers — which actually sound like a good way to start off collaborations!)Next is the University of California (the whole UC system, with UC Berkeley, Los Angeles, … including Lawrance Berkeley National Lab and Los Alamos), who decided not reneged a deal with Elsevier. That’s a lot of people, for the most important public university system in the world. The impact can be quite dramatic…And soon will be the turn of Europe as a whole, with Plan S, starting next year…I can’t wait to see the science literature being unshackled!Still, don’t expect much changes in the conduct of science… “Authors do not publish to get read, they publish to get reviewed.”
Every now and then, I read bits of poetry. Lately, I nibbled on Apollinaire, whose Alcools my father offered me, and I discovered W. H Auden’s Sonnet from China thanks to Shoshana Zuboff:
Falling in love with Truth before he knew Her,
He rode into imaginary lands,
By solitude and fasting hoped to woo Her,
And mocked at those whose served Her with their hands
— W. H. Auden
While I enjoy reading poetry, it only occurred to me recently that poetry is more than a thoughtful collection of word. Poetry is actually philosophy in action — and even the Greeks knew that: ποιεῖν (poiein) means “to make”.
The reason for that has to do with the distinction between axioms and theorems (if you want to learn about that, I have an excellent book for you), or between things that are self-evident and things that are derived. Philosophy, being very rigorous, deals with theorems. Poetry enunciates subtle truths and help us navigate the blind spots of philosophy, such as beauty, love and meaning: everything that sets us in motion.Continue reading
Every year, early June in Ojai, CA, a quiet town half an hour away from Santa Barbara, the Ojai Music Festival takes place.The festival has a glorious history of convening the cream of the crop of new classical music (Stravinski, Messiaan, Boulez and Copland are among the artistic directors who brought their vision to the festival), and is a wonderful crucible for geniuses in music.I went there for the first time in 2016, and I was struck by the brilliance of the pieces I saw – a delightful blend of music from all around the world, mixing ICE and the Indian vocalist Aruna Sairam, under the tutelage of Peter Sellars. I remember being particularly impressed by Leila Adu‘s performance (wonder what she’s up to nowadays…)In the years since, I could just go to Berkeley’s CalPerformances to see the show (Ojai in Berkeley), held a week after the main festival. I fondly recall Vijay Iyer’s take on the Rite of Spring with Radhe Radhe: Rite of Holi, and some standout performances by Tyshawn Sorey, a regular of the festival who never stops to amaze, though I’m more impressed by him in live settings than by the recordings I’ve heard since.Sadly, this year the Berkeley program no longer exists, since since CalPerf’s director Matías Tarnopolski left for Philadelphia. Therefore, I had to drive down the California 1 to see what was happening there.And boy I wasn’t disappointed! This year’s artistic director Barbara Hannigan prepared wonderful program, going from Stravinski (again!) Berg to Steve Reich. Some of the concerts that really struck a chord were Patoulidou performance on Vivier’s Lonely Child, Barbara Hannigan rendition of John Zorn’s Jumalattaret, and Steve Schick leading Terry Riley’s in C (the latter can be on a viewed video of the festival here, at 1h48.)
Not only the artistic content was great, but there is also a sense of passing along the baton (in a way beautifully narrated in Maria Stodtmeijer‘s Taking Risk) to younger artists such as Aphrodite Patoulidou and Yanis Francois.Sure, I’m painting a fawning picture of the festival here, but I’m so drained of creativity that I will leave it to better voices than mine:
At the moment (April 2019), the economy is in a weird quantum superposition of doom (yield curve inversion) and exaltation, with Lyft recently joining the public markets (always loved the irony of the term…)I’ve been talking to a few people involved in driverless cars and AI lately, asking them…. when? They usually tell me soon, the problem they have is that the main drawback with learned neural networks is that they are almost impossible to debug. You can try to get insight on how they work (see the fascinating Activation Atlas), but it’s really difficult to rewire them.And it’s actually pretty easy to hack them — you can easily do some random addition to find noise that will activates the whole network. In the real world, you can put stickers at just the right location and… make every other car crash. Pretty scary… Continue reading
Back in undergrad, I remember being fascinated by the notion of Kolmogorov complexity in computer science.Put simply, the Kolmogorov complexity is the minimal length (number of lines) of the code needed to generate a signal, would it be a mathematical sequence (such as one listed in the OEIS) or an image, irrespective to the size needed to store it. It bears deep relations with the notion of entropy (a great book on the topic is Information Theory, Inference, and Learning Algorithms by the late David MacKay.)For example, a series of eight billion ones in a row would require 1GB of memory, but can be written in a few lines of code:
for i in 1:1e9; print 1; end(To some extent, this is why computer science is often problematic, since one of the goal of a good code is sometimes to reduce its Kolmogorov complexity, but the final code does not show all the lines that have been erased to get there…)In the field of arts, culture and science, this description seems naive: can you really generate a book based on a script, or has it infinite entropy?

I do love Berkeley, with its wonderful atmosphere and its people, daring to live on a different beat!The spring and the fall are the most notably beautiful, and walking in the street is always an amazement.
In the winter, you get the magnolia; in the spring come the fragrant wisteria and the gentle jasmine; the summer has the river flowing to the sea, and the fall, oh the fall with the ginkgo glowing gold on Russell street!
I’ve seen a few friends moving nearby, and they seem to enjoy every bit of it.Here’s a few places to check out:
For the news, check out Berkeleyside.com and the East Bay Express (free, out every Wednesday.) There’s also a lot of other places closer to downtown which are unique: the Back Room, the Pacific Film Archive, Yoga to the people, Half Price Book, Café Panisse, the Strawberry canyon pool, the Skyline boulevard, the Butcher’s son restaurant, the Melo Melo kava bar, and so many other things!
In other news I was recently promoted to a staff position at Lawrence Berkeley National Lab!It’s still tenure track (hopefully the position will be fully secured in two years from now) , but I’m getting closer to my childhood dream: to become a savant.I am extremely lucky to be there, working on a major US scientific infrastructure project (ALS-U), in a fantastic lab with my window literally overlooking the Silicon Valley.
Right now, I’m mostly doing beamline design and simulation, with some wavefront sensing and adaptive optics. Lots of very challenging topics (we have to deal with a laser-like beam hundred times smaller than a hair blasting kilowatts of light), and I’m learning a lot along the way. Amazing times!
Recently, I bought a phone for my family visiting, because roaming costs are so incredibly high for no good reason, and because it becomes hard to navigate the world without the internet (booking, GPS, etc.) I bought at $99, and paid a $50 data plan from Verizon (good deal given that the phone the MSRP is $249, that it’s a very decent phone, and that you can use it anywhere with any carrier — it has GSM, CDMA and everything you need.)On the back of the box, it was mentioned that the phone could be unlocked after $50 had been made. I had just bought $50 of credit for 1 month of 4G with Verizon.When my parents left, I tried to unlock it. It was a bit confusing, but it did work!
