The past was technically sophisticated

The belief in our own technological superiority is amazing. The past was primitive an we are great. Such thoughts are necessary to support the illusion of our belief in a relatively linear technological development. Thatâ??s why I like it when artifacts from the past blow huge holes in our theories of superiority. One such example is the device known as the Antikythera Mechanism (I blogged about this in October last year).

The interpretation and re-interpretation of the meaning and purpose of the Mechanism have been ongoing since its discovery. Recent developments show:

The Antikythera Mechanism is a unique Greek geared device, constructed around the end of the second century bc. It is known that it calculated and displayed celestial information, particularly cycles such as the phases of the moon and a luni-solar calendarâ?¦We find a mechanical realization of this theory in the gearing of the mechanism, revealing an unexpected degree of technical sophistication for the period. (Nature)

For a longer piece on the new interpretations of the Mechanism read this article, and this one, and finally this one all from the New York Times online.

Obey & Mashup

The first time I saw the Obey image was on a t-shirt. Then I saw it on a wall in Barcelona. Since then it appeared and re-appeared on walls around the world. It was naturally there before I saw it, but since then it I have seen it on other walls and t-shirts. Not really sure what it means but it is intriguing.

One of the spookier versions of this images is a mashup from Iran. Not that I have ever been in Iran but I found it over at the Wooster Collective.

Pretty spooky…

Do you hand out your handouts?

Powerpoint is my crutch. As a teacher I have long been dependent upon powerpoint*. But I have also been concerned about the way in which it forms the way I teach and the way in which students learn. Increasingly students have an expectation of getting the lecturerâ??s powerpoint slides â?? Preferably in digital form and in advance of the lecture.

Powerpoint Students
What is a lecture? University is filled with them. They are praised by some and reviled by others (this will be the topic for a future post). To the student the lecture almost defines university life. Therefore it is maybe not all good when the lecture has become confined to the square space and bullet point list defined by presentation software.

Most often I do not hand out my handouts, nor do I provide my powerpoint slides in digital or any other form to my students. This is not an attempt to monopolize or capitalize on my knowledge. To understand the purpose of this we must look at the purpose of powerpoint slides.

Slides are used (in my teaching) for two purposes. First, and foremost, the slides are there to keep me on track to help me keep my thoughts in order. Second, the slides are intended to underscore certain more important thoughts or concepts. Thirdly, the slides may provide light entertainment they can help the listeners to keep listening.

As these points show, the slides are not a replacement for the lecture, lecturer, or literature. So in order to make sure that this message gets across: I do not hand out my handouts.

Powerpoint Lecturers
If the student has become used to being fed with powerpoint slides then what about the lecturer. We have (generalization warning!) become dependent upon powerpoint. Planning a lecture begins with the opening of presentation software. The knowledge we want to transfer is confined by our ability to condense it (knowledge) into squares and lists.

By adding features, such as effects, sounds and images we believe that we are somehow helping the students to understand what we have learned through reading, scientific method and experience.

Handicap Warning
Powerpoint can be, for both students and lecturers, an invaluable support. But letâ??s not forget that the same software can be used as a way in which to hide the fact that no transfer of knowledge is taking place. Each student should as him/herself what they hope to see in the handouts and why they are so eager to obtain the handouts â?? at the same time so disinterested in the original.

Lecturers should stop and think before resorting to powerpoint. If powerpoint is necessary then they should stop and think about the content and its presentation. Would the students be equally served by the applying the old adage â??less is moreâ?? to powerpoint?

Did Einstein hand out handouts?


* the term powerpoint is intented to refer to a generic set of presentation software. The same results are obtained by Open Office presenter, Macâ??s Keynote, or any other such program.

Missed Buy Nothing Day

Yesterday was buy nothing day. All I can say is that the buy-nothing idea was not particularly noticeable at Ikea. So I must consider myself a buy-nothing failure. Here is some information about the day.

Every November, for 24 hours, we remember that no one was born to shop. If youâ??ve never taken part in Buy Nothing Day, or if youâ??ve taken part in the past but havenâ??t really committed to doing it again, consider this: 2006 will go down as the year in which mainstream dialogue about global warming finally reached its critical mass. What better way to bring the Year of Global Warming to a close than to point in the direction of real alternatives to the unbridled consumption that has created this quagmire?

Oh well, there is always next year…

Military Tourism

The first day at the Swedish Armed Forces Academy (at Karlberg Castle) is over and today is the second, and final, day. Yesterday we had a tour of the facilities and also a long open discussion between the project members and the rapporteurs.
Apparently the Swedish military academy is the oldest in the world. The building is filled to the brim with old military nick-nacks which seem to be (almost) spread out at random. The more representative rooms are better arranged but the room we had our discussions in contained two oil portraits of 16th century characters an Admiral and an adviser to the King and two ugly worn down wood and leather sofa’s from the 1970s, the kind that you find in the clubhouse of the local chess of football club  – very postmodern.

The discussions are going well. Interesting topics and interesting people. One side-topic which came up was the notion of military tourism. Military officers traveling to other military units and living their reality for a while. This was particularly interesting when after discussing this modern version we say the names of those fallen in battle in the Karlberg chapel – it was filled with exotic locations and plenty of foreign names.

Walking on the wild side

If I was in Singapore I would be facing a prison sentence for doing what I am doing now. (Explanation). The hotel has free wifi for its guests and the receptionist gave me the codes but I chose the wrong (?) wireless and the neighbors let me in.  Many swedes leave their wifi networks open and I must say that I have a hard time figuring why this should be wrong. Additionally I also have a hard time figuring out why people in cities who have open networks
should be annoyed that others surf on their infrastructure.

If you don’t want to let others surf the close the network. But unless you experience serious lag due to all you neighbors surfing via your net then why bother?

Actually allowing neighbors to surf your wifi may be in violation of the service agreement between you and your broadband provider. But lets not go there. Just let me mangle Blanche’s line in Tennessee Williams’ “A Streetcar Named Desire”: I must say I am grateful for the kindness of strangers.*

* Real line should be: “Whoever you are, I have always depended on the kindness of strangers.” but somehow this does not really apply to wifi…

10 Arguments Against DRM

Learn Out Loud presents ten arguments against DRM. This is a good way to quickly get up to speed with the issue of digital restrictions management (DRM). The most important is that DRM changes the who controls our media and infrastructure. In the long run this control may also begin to control the way in which we think.

Grey Saturday

Yupp another rainy Saturday has rolled around. While taking a walk around town I managed to pick up Vilém Flusser‘s book Towards a Philosophy of Photography which seems very exiting. Also discovered that the cool exhibition by Mattias Adolfsson (blogged about him earlier and he also has a blog with images) was still available and so was my favourite picture. So I bought the Beatnik Dragon.

Not a bad bit of procrastination – but now it’s back to the the real writing. Or rather as LP would say – the stuff that I really get paid for…

Happy Toilet, Healthy Life

Right now in Bangkok itâ??s the 6th annual World Toilet Forum. The Forum has as its slogan: â??Happy Toilet, Healthy Lifeâ?? â?? which I must say if you are going to pick words to live by then these are as good as many others! Much better than the ridiculous â??Dulce et Decorum Est Pro Patria Moriâ?? translated: It is sweet and noble to die for your country (If you donâ??t think its ridiculous then you should read Wilfred Owen or read more current affairs).

Anyway back to the original subject of Happy Toilets. Not only is there a World Toilet Forum but there is also a World Toilet Organisation, which I thought must have been a satire on the WTO, and there is also a World Toilet College in Singapore, whose nr 2 objective (sorry I couldnâ??t resist it) is â??To establish Singapore as the premier training hub for the restroom industry.â??

The WTO site (Toilet not Trade) also has a selection of photographs entitled Beautiful Restroom Images – but I thought that I would provide something more low-tech so this is from the public latrines in Ostia

Why the sudden interest? Well I just wanted you all to know that tomorrow is the International Toilet Day – a fitting tribute to the technologicalization of the natural processes. What can I say? Except â??Happy Toilet, Healthy Lifeâ??

Oh and of course you can also buy t-shirtsâ?¦

Back from the dead

Wow! What a roller coaster! My computer died causing much pain, agony, wailing and gnashing of teeth.

Today, after using Data Rescue II and spending the whole day (more or less) watching software scan, find, rescue, copy, delete, format and finally install – I’m back! That’s right the computer has been rescued by the prompt, patient and heroic ministrations of the superwizard of support LP (I will not use his real name so that he can maintain his secret identity).

All my mail is back. All my friends have been grinning and making evil comments about backups and other safety measures. When not watching the screen I have been walking around as an example to others: “Look there he is… he didn’t back up and now he is toast…” A tale to scare the grandchildren with.

So now I will solemnly promise to make even more frequent backups and to never pop mail again (yes I shall embrace imap with the fervor of a convert).

Lessons learned you think? and yet… I don’t know. Maybe it was too easy, maybe I didn’t suffer enough…
