Lost in Google Translate: How Unreasonable Effectiveness of Data can Sometimes Lead Us Astray

I’ve recently received an e-mail in Dutch from the Belgian teacher of my 7.5-year-old son, and even though my Dutch is more than enough to understand what his teacher wrote, I also wanted to check it with Google Translate out of habit and because of my professional/academic background. This led to an interesting discovery and made me think once again about artificial intelligence, deep learning, automatic translation, statistical natural language processing, knowledge representation, commonsense reasoning and linguistics.

But first things first, let’s see how Google Translate translated a very ordinary Dutch sentence into English:

Interesting! It is obvious that my son’s teacher didn’t have anything to do with a grinding table (!), and even if he did, I don’t think he’d involve his class with such interesting hobbies. 🙂 Of course, he meant the “multiplication table for 3”.

Then I wanted to see what the giant search engine, Google Search itself knows about Dutch word of “maaltafel”. And I’ve immediately seen that Google Search knows very well that “maaltafel” in Dutch means “Multiplication table” in English. Not only that, but also in the first page of search results, you can see the expected Dutch expression occurring 47 times. Nothing surprising here: Read the rest of this entry »

A visit to the largest computer museum in the world: The Heinz Nixdorf MuseumsForum

It all started more than seven years ago, when I read a short article in January, 2010 issue of Communications of the ACM, titled “Great Computing Museums of the World (Part One)“.

“The Heinz Nixdorf MuseumsForum (HNF; in Paderborn, Germany, is the world’s largest computer museum. The museum, which is also an established conference center, showcases the history of information technology—beginning with cuneiform writing and going right through to the latest developments in robotics, artificial intelligence, and ubiquitous computing.

The multimedia journey through time takes visitors through 5,000 years of history, starting with the origins of numbers and writing in Mesopotamia in 3000 B.C. and covering the entire cultural history of writing, calculating, and communications. Alongside typewriters and calculating machines, the exhibition shows punched card systems, a fully functioning automatic telephone exchange system from the 1950s, components from the earliest computer (which filled a whole room), over 700 pocket calculators, and the first PCs. Work environments from different centuries are also staged in the exhibition.

The exhibition highlights include fully functioning replicas of the Leibniz calculating machine and the Hollerith tabulating machine, a Thomas Arithmometer dating from 1850, a Jacquard loom operated with punched tape, components of the ENIAC from 1945, the on-board computer from the Gemini space capsule, the Apple 1, a LEGO Turing machine, and Europe’s largest collection of cipher machines. One of the current attractions at HNF is the world’s most famous automaton: Wolfgang von Kempelen’s chess playing machine, the Chess Turk, which dates from the 18th century.”

I was more than impressed, and wanted to visit Paderborn to see the world’s largest computer museum. I knew it was just a few hours away by car from Antwerp, but I’ve always postponed going there for various reasons. I didn’t want there to go alone, and I knew I needed someone like-minded enough to accompany me on this “nerdy” journey. Finally, last week, I and a physicist / data scientist friend of mine decided to go there, notwithstanding the weather conditions, and very snowy German highways.

I think this is the only museum where digital relics from my childhood and youth (1980s and 1990s) are considered as museum-worthy as replicas of 5000 year old Sumerian tablets! 🙂 It was pure joy and fascination to visit the halls of the museum, and be guided by very thematic and knowledgeable, gentle robots. One of them, Victoria, was a sight to be seen! The other one was also great, and you can watch “him” in action:

After the course: Tales from the Genome, Introduction to Genetics & A Few Resources

Now that I’ve finished the Tales from the Genome, Introduction to Genetics course, I’d like to note some of the related resources (some of the links are related to, a company that sponsored the course, it is the same company whose genetic analysis kit I have used to learn more about my genome and the mutations I have. Unfortunately, in the meantime I have also learned that they were forced to stop selling their kits, luckily I already had my results before that happened).

Notes from the event: “Open Science. The key to more scientific integrity?”

Readers of this blog could easily guess my program for this Thursday evening after reading the news “Brussels university welcomes Wikipedia founder“. I have immediately registered for “Open Science. The key to more scientific integrity?” event at Vrije Universiteit Brussel, because I didn’t want to miss the opportunity to listen to Jimmy Wales, the co-founder of Wikipedia, as well as the other notable speakers, namely Prof. Em. André Van Steirteghem and Michel Bauwens.


It was nice to see be a part of an enthusiastic audience and all of the speakers delivered interesting talks full of insights. For example, thanks to this event, I learned that emeritus Prof. André Van Steirteghem is co-secretary of COPE (Committee on Publication Ethics) and once again was disappointed to hear about the rise of fraudulent research in Belgium, as well as in other European countries. Next speaker, Michel Bauwens talked about his perspectives on post-capitalistic social structures and peer-to-peer production mechanisms, using interesting terminology such as metarchical capitalism. At the end of his talk, he also drew attention to Wikipedia, and voiced his concerns about some of the rules such as notability: Apparently he was not found notable enough for Wikipedia. He claimed that since this ‘notability’ rule was established, the curve of contributions to Wikipedia became almost flat, indicating a particularly problematic situation, as well as the power struggles in Wikipedia.

Jimmy Wales, the co-founder of Wikipedia and keynote speaker of the event was the final speaker and he definitely had a great, enthusiastic presence on the stage. His presentation not only gave a brief and good summary of the history of Wikipedia, its structure, its operating principles and philosophies, but also interesting statistical facts about one of the most popular and valuable sites on the Internet regarding languages and countries. Probably one piece of fact that everyone will easily remember was the following: Read the rest of this entry »

A day full of space research at ESTEC Open Day in Noordwijk, Netherlands

I have to admit that I haven’t expected so much fun and science in a single day when I have registered for ESTEC Open Day about one month ago in order to visit the European Space Research and Technology Centre (ESTEC). This huge center is the European Space Agency‘s main technology development and test centre for spacecraft and space technology. I think it very much deserves to be called the CERN of Space Research, accommodating about 2500 engineers, technicians and scientists who work hands-on with mission design, spacecraft and space technology.

From Space Expo to the various ESTEC facilities, it turned out to be quite an adventure. Not only did I learn a lot about the wonderful history of ESTEC, but I also had the opportunity to witness very interesting scientific demonstrations that were also impressive from an engineering point of view. Even though I have already worked in the space industry for 2 years and been to ESTEC for a few meetings, this fact did not lessen my excitement today. I’m very much looking forward to the next public event at ESTEC and recommend the readers of this blog to be on the watch, too.

Book review: How the Hippies Saved Physics: Science, Counterculture, and the Quantum Revival

David Kaiser brings a whole new perspective to the concept of history of science in his book “How the Hippies Saved Physics: Science, Counterculture, and the Quantum Revival” (or maybe we should call it journalism of science, because almost all of the heroes of this wonderful book are alive). One of the central themes of the book revolves around the classical question of “what is the line between science and pseudoscience?” and others such as “do people move between categories, and if they do, does that lead to any scientifically valuable results?”. hip

For the reader who thinks science ‘progresses’ (whatever that progress means) in a linear, stepwise manner, the book is definitely full of surprises: expect the unexpected from a turbulent period of intellectual history throughout 60s and 70s, reaching to 90s and well to the 21st century. You will meet heroes such as Feynman (in very interesting settings), as well as the names probably you haven’t heard before, and you will learn that inspirations for scientific ideas can come from very unexpected domains.
