Images – Portugal (1A – top left, original input satellite image below), geodesically stretched by one of my Mathematical Morphology algorithms, in order to represent real travel times from each of the 18 regional districts in Portugal, to the rest of the territory. From the 18, three capital districts are represented here. As departing from Lisbon (1B – top right), from Faro (1C – South of Portugal, bottom left), and from Bragança (1D – North-East region, bottom right). [World Exposition, Lisbon, Territory pavilion, 1998].
For my complete and positive surprise, their interview ended with some new examples, being one of my old works referred (from 57m 12s up to 60m 26s on http://camaraclara.rtp.pt/#/arquivo/131 ). It’s a long story on how I ended doing these kind of maps. Part of it, it’s here. During 1998, the World Exposition was in Portugal, and I got invited to present a set of 18 different maps from the Portuguese territory. So I decided to geodesically stretch the travel distances from any of the 18 different capital districts, to the rest of the territory, in order to represent travel Time not Distance, or Distance as time. For that, I have coded new algorithms based on Mathematical Morphology (MM), taking in account every road (from main roads to regional, check some images below), from which I applied different MM operators.
Unfortunately, many of those maps are now lost. I did tried hard to find them from my old digital archives, but only found those above, which represent the departure from Lisbon (the Capital), Faro and Bragança. So, if by any reason you happen to have some photos from the 1998’s World Exposition in Lisbon, inside the Territory pavilion, I would love to receive them.
A sketchy summary of this TV program went on something like this (the poor translation is mine): At the year Google promises to launch his first and exhaustive world-wide open-access digital cartography of the African continent, Joaquim Ferreira do Amaral, passioned by the Portuguese World Discover History and collector of historical maps, joins as guest with Manuel Lima, the Portuguese information designer that recently Creativity magazine has considered one of the top bright minds along with Google and Amazon founders, debating the importance of “navigating” reality with a map. From the Portuguese cartographic history, know to be the best in the XV and XVI centuries, up to the actual state-of-the-art in this area, from which Manuel Lima is considered to be one of the top researchers at global scale.
How wings are attached to the backs of Angels, Craig Welsh (1996) – Production by the National Film Board of Canada (nfb.ca): In this surreal exposition, we meet a man, obsessed with control. His intricate gadgets manipulate yet insulate, as his science dissects and reduces. How exactly are wings attached to the back of angels? In this invented world drained of emotion, where everything goes through the motions, he is brushed by indefinite longings. Whether he can transcend his obsessions and fears is the heart of the matter (from Vimeo).

“It takes you 500,000 microseconds just to click a mouse. But if you’re a Wall Street algorithm and you’re five microseconds behind, you’re a loser.” ~ Kevin Slavin.
TED video lecture – Kevin Slavin (link) argues that we’re living in a world designed for – and increasingly controlled by – algorithms. In this riveting talk from TEDGlobal, he shows how these complex computer programs determine: espionage tactics, stock prices, movie scripts, and architecture. And he warns that we are writing code we can’t understand, with implications we can’t control. Kevin Slavin navigates in the “algoworld“, the expanding space in our lives that’s determined and run by algorithms (link at TED).
Video lecture – In this new RSA Animate, Manuel Lima, senior UX design lead at Microsoft Bing, explores the power of network visualisation to help navigate our complex modern world. Taken from a lecture given by Manuel Lima as part of the RSA’s free public events programme.
Network visualization has experienced a meteoric rise in the last decade, bringing together people from various fields and capturing the interest of individuals across the globe. As the practice continues to shed light on an incredible array of complex issues, it keeps drawing attention back onto itself. Manuel Lima is a Senior UX Design Lead at Microsoft Bing and founder of VisualComplexity.com, and was nominated as ‘one of the 50 most creative and influential minds of 2009’ by Creativity Magazine. He visits the RSA to explore a critical paradigm shift in various areas of knowledge, as we stop relying on hierarchical tree structures and turn instead to networks in order to properly map the inherent complexities of our modern world. The talk will showcase a variety of captivating examples of visualization and also introduce the network topology as a new cultural meme. (from RSA, lecture link).
Video Documentary – Code Rush (www.clickmovement.org/coderush), produced in 2000 and broadcast on PBS, is an inside look at living and working in Silicon Valley at the height of the dot-com era. The film follows a group of Netscape engineers as they pursue at that time a revolutionary venture to save their company – giving away the software recipe for Netscape’s browser in exchange for integrating improvements created by outside software developers.
” (…) code (…) Why is it important for the world? Because it’s the blood of the organism that is our culture, now. It’s what makes everything go.“, Jamie Zawinski, Code Rush, 2000.
The year is early 1998, at the height of dot-com era, and a small team of Netscape code writers frantically works to reconstruct the company’s Internet browser. In doing so they will rewrite the rules of software development by giving away the recipe for its browser in exchange for integrating improvements created by outside unpaid developers. The fate of the entire company may well rest on their shoulders. Broadcast on PBS, the film capture the human and technological dramas that unfold in the collision between science, engineering, code, and commerce.
Video – Animaris Gubernare (AG), is one of the most recent Theo Jansen’s Strandbeest‘s (strandbeest.com) machine animals. Born in October 2010, AG died out in October 2011. It had two external (rolling) wind stomachs which serve as an anchor against strong winds.
Since 1990, only by using plastic tubes, lemonade bottles and air pistons as logic gates, powered by wind, Theo Jansen has produced some quite incredible machine animals. His creatures are designed to move – and even survive – on their own. In some cases he have recurred to Evolutionary Computation (more) as a mean to optimize their shape in order to longer survive hard storms and salt water. He briefly explains:
“(…) Since 1990 I have been occupied creating new forms of life. Not pollen or seeds but plastic yellow tubes are used as the basic material of this new nature. I make skeletons that are able to walk on the wind, so they don’t have to eat. Over time, these skeletons have become increasingly better at surviving the elements such as storm and water and eventually I want to put these animals out in herds on the beaches, so they will live their own lives (…)”, Theo Jansen, in Strandbeest (strandbeest.com).
But he goes a step further. Not he only develop sensors (for water sensing) as well as a full Brain, a binary step counter made of plastic tubes, which could change his pattern of zeroes, overtime, and adapts. Have a look (minute 6, second 33) … :
Video – Jansen‘s Lecture at TED talks, March 2007 (Monterey, California). Theo Jansen creates kinetic sculptures that walk using wind power (featured in a few previous short sifts), here he explains how he makes them work. Incredibly, he has devised a way to optimize the shape of the machine’s parts and gait using a genetic algorithm running on a PC and has actually made logic gates out of the air pistons making up the machines. His work attests to a truly jaw-dropping intelligence.
Video – Water has Memory (from Oasis HD, Canada; link): just a liquid or much more? Many researchers are convinced that water is capable of “memory” by storing information and retrieving it. The possible applications are innumerable: limitless retention and storage capacity and the key to discovering the origins of life on our planet. Research into water is just beginning.
Water capable of processing information as well as a huge possible “container” for data media, that is something remarkable. This theory was first proposed by the late French immunologist Jacques Benveniste, in a controversial article published in 1988 in Nature, as a way of explaining how homeopathy works (link). Benveniste’s theory has continued to be championed by some and disputed by others. The video clip above, from the Oasis HD Channel, shows some fascinating recent experiments with water “memory” from the Aerospace Institute of the University of Stuttgart in Germany. The results with the different types of flowers immersed in water are particularly evocative.
This line of research also remembers me back of an old and quite interesting paper by a colleague, Chrisantha Fernando. Together with Sampsa Sojakka, both have proved that waves produced on the surface of water can be used as the medium for a Wolfgang Maass’ “Liquid State Machine” (link) that pre-processes inputs so allowing a simple perceptron to solve the XOR problem and undertake speech recognition. Amazingly, Water achieves this “for free”, and does so without the time-consuming computation required by realistic neural models. What follows is the abstract of their paper entitled “Pattern Recognition in a Bucket“, as well a PDF link onto it:

[…] Abstract. This paper demonstrates that the waves produced on the surface of water can be used as the medium for a “Liquid State Machine” that pre-processes inputs so allowing a simple perceptron to solve the XOR problem and undertake speech recognition. Interference between waves allows non-linear parallel computation upon simultaneous sensory inputs. Temporal patterns of stimulation are converted to spatial patterns of water waves upon which a linear discrimination can be made. Whereas Wolfgang Maass’ Liquid State Machine requires fine tuning of the spiking neural network parameters, water has inherent self-organising properties such as strong local interactions, time-dependent spread of activation to distant areas, inherent stability to a wide variety of inputs, and high complexity. Water achieves this “for free”, and does so without the time-consuming computation required by realistic neural models. An analogy is made between water molecules and neurons in a recurrent neural network.

Video – NASA | SDO’s Ultra-high Definition View of 2012 Venus Transit. (June 5 2012).
“Seeing these pictures is like a time machine. We link onto those who have seen it years ago, as well those who will see it centuries from now.” (link)
Launched on Feb. 11, 2010, the Solar Dynamics Observatory, or SDO, is the most advanced spacecraft ever designed to study the sun. During its five-year mission, it will examine the sun’s atmosphere, magnetic field and also provide a better understanding of the role the sun plays in Earth’s atmospheric chemistry and climate. SDO provides images with resolution 8 times better than high-definition television and returns more than a terabyte of data each day.
On June 5 2012, SDO collected images of the rarest predictable solar event–the transit of Venus across the face of the sun. This event happens in pairs eight years apart that are separated from each other by 105 or 121 years. The last transit was in 2004 and the next will not happen until 2117.
The videos and images displayed here are constructed from several wavelengths of extreme ultraviolet light and a portion of the visible spectrum. The red colored sun is the 304 angstrom ultraviolet, the golden colored sun is 171 angstrom, the magenta sun is 1700 angstrom, and the orange sun is filtered visible light. 304 and 171 show the atmosphere of the sun, which does not appear in the visible part of the spectrum.
Fig. – Handout image by NASA (click to enlarge) shows the planet Venus at the start of its transit of the Sun, June 5, 2012. One of the rarest astronomical events occurs on Tuesday and Wednesday when Venus passed directly between the Sun and Earth, a transit that won’t occur again until 2117, 105 years from now. The first observation of the Transit of Venus was made by Salford stargazer William Crabtree in 1639 (mural drawing at Manchester Town Hallby by Ford Madox Brown – image from Wikipedia).

[…] Swing music, also known as swing jazz or simply swing, is a form of jazz music that developed in the early 1930s and became a distinctive style by 1935 in the United States. Swing uses a strong rhythm section of double bass and drums as the anchor for a lead section of brass instruments such as trumpets and trombones, woodwinds including saxophones and clarinets, and sometimes stringed instruments such as violin and guitar, medium to fast tempos, and a “lilting” swing time rhythm. The name swing came from the phrase ‘swing feel’ where the emphasis is on the off-beat or weaker pulse in the music (unlike classic music). Swing bands usually featured soloists who would improvise on the melody over the arrangement. The danceable swing style of bandleaders such as Benny Goodman and Count Basie was the dominant form of American popular music from 1935 to 1945. The verb “to swing” is also used as a term of praise for playing that has a strong rhythmic “groove” or drive. […] from Wikipedia (link).
nota bene – tomorrow is Jazz day, isn’t it?!
“I met Death today. We are playing chess. (…) My life has been a futile pursuit, a wandering, a great deal of talk without meaning. I feel no bitterness or self-reproach because the lives of most people [plague] are very much like this. But I will use my reprieve for one meaningful deed.”, Antonius Block.
The Seventh Seal (Det sjunde inseglet). Written and directed by Ingmar Bergman, Sweden 1957 – (…) Disillusioned knight Antonius Block and his squire Jöns return after fighting in the Crusades and find Sweden being ravaged by the plague. On the beach immediately after their arrival, Block encounters Death, personified as a pale, black-cowled figure resembling a monk. Block, in the middle of a chess game he has been playing alone, challenges Death to a chess match, believing that he can forestall his demise as long as the game continues. Death agrees, and they start a new game. The other characters in the story do not see Death, and when the chess board comes out at various times in the story, they believe Block is continuing his habit of playing alone. (…)
(…) In the confessional, the knight says “I use a combination of the bishop and the knight which he hasn’t yet discovered. In the next move I’ll shatter one of his flanks.” Death (in disguise as the priest) replies “I’ll remember that.” When they play by the beach, the knight says: “Because I revealed my tactics to you I’m in retreat. It’s your move.” Death captures his opponent’s knight. “You did the right thing“, states the knight, “you fell right in the trap. Check! Don’t worry about my laughter, save your king instead.” Death‘s response is to lean over the chess board and make a psychological move. “Are you going to escort the juggler and his wife through the forest? Those whose names are Jof and Mia and who have a small son.” “Why do you ask?” says the knight. “Oh, no reason”, replies Death“. (…) from Wikipedia [link] (Nota bene – bolds and underlines are mine).
Sound/Video – willterminus (YouTube link) says: “I was bored so I wanted to see if I could get free dial up internet so I found that NetZero still has free service so I put in the number and heard the glorious sound of the Dial-up.

The above artificial ecosystem investigates the characteristics of the simulated environment through the use of agents reactive to pheromone trails. Pheromones spread through the fluid and are transported by it. The configuration of the reefs will be developed therefore in areas with less chance of stagnation of pheromones (done in Processing, from Alessandro Zomparelli, 2012).

“I saw them hurrying from either side, and each shade kissed another, without pausing; Each by the briefest society satisfied. (Ants in their dark ranks, meet exactly so, rubbing each other’s noses, to ask perhaps; What luck they’ve had, or which way they should go.)” — Dante, Purgatorio, Canto XXVI.
Video documentary: A 15-minute program produced from February 1949 to April 1952, Kieran’s Kaleidoscope presented its writer and host in his well-acquainted role as the learned and witty guide to the complexities of human knowledge (Production Company: Almanac Films). This is probably the most genuinely entertaining of all the John Kieran‘s Kaleidoscope films. On Ant City (1949) [Internet Archive] produced by Paul F. Moss, the poor ants are anthropomorphized to the nth degree; we even hear the Wedding March when the “queen” and her drone fly away from the nest. Kieran‘s patter has never been more meandering; he sounds like a befuddled uncle narrating home movies. Clumsy but enjoyable.
