Slow philosophy. [Weekly Head Voices #64]

I’ve spent days writing this post in my head, and now it’s taken more than two weeks to get done. It’s not that I have something complicated or difficult to tell you, it’s just that I was privy to three absolutely awesome weeks of vacation in an undisclosed location to the very far south of my current coordinates, during which I attained ultimate levels of relaxation that caused my brain to shut-down large parts of itself. The only parts that managed to remain online were those dedicated to slow living, appreciation of people and surroundings and, finally, deep thought. My brain is currently taking its sweet time to come fully online again.

Oh well.

I did bring you a photo of Disa Uniflora, a special little orchid that likes living close to little waterfalls, for example just like the one that can be found on your hike up Leopard’s Kloof. Look:

Pretty Disa in Leopard's Kloof.

As is usual for sunny vacations during which we transition into a new year, a number of realizations and resolutions slowly bubbled up to the surface from some usually submerged part of my consciousness. I’d like to share some of them with you:

Life goals are bad. Let’s stop doing them. The problem is that humans are awesome at adaptation. Unfortunately this means that two days after having celebrated your latest epic life achievement, you’re bored with it. Some people even get bored with their lives in general, and then buy a leather jacket and a motorbike because they think that that’ll somehow solve the problem, only to get bored with their new image soon after. Fortunately, there is a way to sidestep the problem quite elegantly. Don’t set life goals, but rather set life directions. Instead of defining the point that you want to go towards, define your preferred direction. If you do it right, you’ll pass those points as you go along in any case, except you won’t land in the depressing goal vacuum right after reaching the point that you’ve been moving towards for so long, because you’re motoring along in a direction, and that’s what’s important. To those more mathematically inclined, ignore the life function, rather design its derivatives. This is a practical way of applying the well-known addage that life is about the journey, and not the destination.

Disconnecting is good. I do love the internet. I also think it’s one of the most awesome achievements of the whole of humankind ever, and it really empowers humans everywhere. I’m more or less addicted to being constantly connected, having constant access to the sum total of human knowledge and in principle to a large percentage of my fellow humans. However, there is a fine line between having constant access and being constantly interrupted by too many not necessarily valuable packets of data. We’re very vulnerable to this latter situation, due to our brain chemistry being optimized by all of evolution for novelty, and for foraging, so we keep on clicking on “refresh”, and our ears perk up whenever a phone goes “ping”. However, when not being interrupted, human thought gets the room it needs to grow and deepen, into importance and into impact.

I’ve also been thinking about consumption. I’d like to do much less of that, and when I do, I’d prefer to consume quality. In my thoughts, it was primarily about information, but it applies to many other things. It’s an ongoing process.

I’m adding all of these to my growing list of little life tips. As regular readers of this blog, you know some of these by now: Keep on  striving for balance and harmony, focus on the now, create value, study your manual, and, most importantly, drink lots of coffee. One day I’m going to combine them all nicely into the Unified Dogma of  Me (UDM) and then I’ll start a sect. Seriously though, it’s quite challenging keeping these and the other ones in the front of my mind all the time. The UDM would definitely help. And I could start a sect.

One more thing before you go: I came across this recent PNAS article via the science pages of my newspaper. William Ratcliff and colleagues at the Michigan State University showed with a terribly simple experiment that single-celled yeast cells can evolve into multi-cellularity quite quickly. Pouring yeast from one test tube into another about 60 times, an action that favours, or selects, yeast cells that clump together, resulted into a multi-celled organism: The clumped together yeast cells started showing internal specialization. Pretty awesome results, especially considering the fact that you could probably reproduce this experiment in your kitchen.

That’s all for this week kids. Have fun evolving!

Astropsychonaut. [Weekly Head Voices #63]

I recently came across this hauntingly beatiful time-lapse view of Earth made from the ISS (the International Space Station! Yes, we have one!):

Watching this, my nostalgia flared up. You see, I’ve been addicted to science fiction ever since I can remember. It started with Buck Rogers, and the original Star Trek, and only got much worse when I discovered Arthur C. Clarke, Ray Bradbury, Isaac Asimov and Douglas Hill. I find Kubrick’s 2001 and even the sequel movie 2010 beautiful.

For the longest time, I wanted to be an astronaut. I think I still do.

I believe I might have thought that my career plans would be seen as childish when I wrote this short piece for school detailing my life plans when I was 7 or 8 (late eighties, not saying anymore):

My life plans as a 7 or 8 year old. My brother found this somewhere and put it on facebook. I wonder what it would be like to go back in time and explain that concept to myself.

For those of you without the required Afrikaans background, here is a short translation, as true as possible to the original:

When I gow up, I’d like to work with computers, because then I’ll become really smart and I’ll know more about the outdoors and nature. As I grow older, I’ll become a professor, because perhaps I’ll find a cure for leprosy and after that I’m going to study to be a millionaire, because then I’ll go abroad or around the world.

Not a bad plan for a 7 or 8 year old, if you don’t mind me saying so myself. This note has in fact reminded me that there’s still more than enough decisions to be made and work to do, so I’ll have to postpone becoming an astronaut for a little while longer. At least by the end I’m going to end up a rich traveller, which is probably not a bad deal.

In other news this week:

  • It seems like just the other day that I made my 400th connection on LinkedIn. I’m happy to report that I broke the 500 barrier two weeks ago, and now I have that fancy looking “500+” next to my name. I finetuned my headline to celebrate the occasion, after which I promptly got approached by a head hunter.
  • Jonathan Dyer is the guru of facial hair. Check out all the beard types and accompanying facial expressions that he has mastered. Yes, that’s a hint of jealousy that you detect in my writing.
  • More reasons to love the coffee: Giving rats the equivalent of what a human gets after two cups of coffee, the caffeine caused nerve cells in a certain region of the hippocampus to show a significantly bigger burst of activity. These strengthened synapses might have a role in learning and memory. Read this summary on boingboing and the article on Nature Neuroscience.
  • In an exceptionally disappointing move, South African parliament has passed a new secrecy bill that gives members of government the power to declare information a state secret, thus deterring honest-keeping journalists and other whistle-blowers with a 25 year jail sentence. Desmond Tutu sums it up nicely when he says that this makes the State answerable only to the State.

If this new bill manages to make it through the constitutional court as well, the country is going to take a giant step backwards. At least we’ll have facedrink to cheer us up again!

You have beautiful ize. [Weekly Head Voices #62]

I completely lack the genes that usually cause human males to have a thing for cars, but I do love Top Gear. This trailer for a fictional 60s detective show, made by Jeremy Clarkson, James May and Richard Hammond, encapsulates many of the reasons why:

Moustaches, guns, girls, cars and Hammond karate-chopping the porter at Playboy Club London for absolutely no reason whatsoever at 41 seconds can be nothing but 100% pure AWESOME.

It’s crazily busy at the moment, for a large part due to the extra load of having to teach and revamp, AT THE SAME TIME, the TU Delft’s postgraduate Data Visualization course. I’ve chucked out the written exam and the structured lab work, and exchanged it for paper reading, class discussion and four independent projects, inspired by positive experience with my Medical Visualization Ninja Training Course (third year in the running, Ninjas all over the place!), the postgraduate InfoVis course I gave at Stellenbosch and of course the teaching materials of esteemed colleagues at UBC, Harvard, Berkeley and Stanford. With a bit of luck, we will soon deliver a whole class of new-style DataVis Ninjas.

At a recent conference, I ran into an erudite half-British colleague from the far North, who in a few minutes almost managed to turn my world into rubble. You see, I’ve always proudly promoted the use of the -ise forms of certain words, such as visualise, realise, colonise and so forth, these being examples of British English. (Obviously, I adapt when American English is required.)

It turns out that, as is the case with life in general, it’s unfortunately not as simple as that.

It turns out that many of the -ise words are originally from the Greek or the Latin with “-ize” endings, and therefore the Oxford spelling prefers their use, although it accepts the “-ise” forms as well. On the other hand, the Cambridge University Press, as well as the mainstream media and most of the public in Britain and the former colonies, has a strong preference for the “-ise” forms. Certain other words like for example advertise, advise and surprise always take the “-ise” form in British English.

So now I’m faced with this conundrum. It would otherwise not have been such an issue, but the words “visualise” and “visualisation” come up quite often during my work day. Sticking to “-ise” is easier and still correct when in British English mode, but “-ize” for those few words of Greek  and Latin origin could perhaps be considered more correct, and has the great advantage of allowing me to standardise on “visualize” as the canonical form of that important term. However, then I would run the risk of confusing the “-ize” and the true “-ise” words in Oxford English, potentially leading to painful embarrassment at the many cocktail parties that I frequent.

So you see, the Universe is just full of mysteries. Another mystery that has plagued humankind for decades, is what would happen if Stephen Hawking and Albert Einstein got involved in a rap battle. Well humankind, wonder no more:

Ok kids, thank you for tuning in again. Have a great week, I hope to see you again soon!

Happiness slingshot. [Weekly Head Voices #61]

Make sure you won’t be disturbed for the next 2 minutes and 57 seconds, and then focus your full attention on this marvelous YouTube clip:

Yes people, there are apparently some brilliant human beings, the pinnacle of our society you might say, who took the time to construct a giant slingshot with which they then proceeded to shoot each other through the blue summer sky. This is the sign that we, the human race, must be doing something right.

Because I need all the time that I can get to play may part in being a good human, I will now switch to Bullet Time(tm):

  • IEEE VisWeek 2011, Mind-Blowingly Awesome Visualization Conference, took place in week 43. For the first time in years, I was NOT there. The TNR went and came back inspired. My fearless and revered ex-leader Frits Post received the IEEE VGTC Visualization Career Award, which is yet another official recognition of his awesomeness. I hope he still has some space on the mantelpiece next to the Eurographics Honorary Fellow award.
  • Through the #visweek conference twitter stream and some of the blogging that was going on, I was able to follow the conference at a distance. There was a Blogging about Visualization BoF (birds of a feather, a kind of informal meeting to discuss some topic of interest; also read Dominikus Baur’s blog report), which motivated me to revive the MedVis.org webblog! We even have a twitter account now. If you have even a mild interest in medical visualisation or imaging, please subscribe via email, your RSS reader or the twitter account.
  • This blog won one of Joe’s official SA Blog Awards! Buy me a beer when you see me.
  • A real Italian explained to me that putting sugar in your espresso is entirely acceptable and even desirable. Herewith I’m going to stop feeling ashamed about my sugar-in-espresso habit. I’m not sure what I was thinking that combining two of the best substances known to humans was a sin.
  • After spending some serious quality time with The Email Game, I wrestled both of my overgrown inboxes to the ground. Lessons learnt: 1) Even the thin layer of gamification offered by The Email Game was sufficient to motivate me to start and finish a task I’ve been dreading for weeks. 2) Inbox Zero actually is more important than I’ve recently come to think. The trick is deciding when exactly you’re going to empty it.
  • Here’s a picture of a hedgehog after a bath:

It's a hedgehog. After a bath!

So recently I was having a conversation with someone in a bar. Soon the question came up: What are you striving for in your work?

Imagine my surprise when I didn’t have an answer ready. I was surprised, because I usually spend a significant amount of time on introspection, pondering the usual questions:

  1. What makes me happy?
  2. Why are we here?
  3. What should I strive for?

I mostly have answers to all of these and more, often involving coffee drinking in some form, along with a healthy dose of perspective, and harmony. However, due to general work-related business the past few months, my moments of introspection have been few and far between. As is the case with these types of philosophical guidelines, one does need to spend time regularly pondering them, else they sink quickly deeper below the surface of everyday life.

So I spent some time trying to remember what it was that I was striving for in work. Fortunately, not that far below the surface, I found it again:

Create value.

That’s really all there is, but it works for me.

Visual Boy. [Weekly Head Voices #60]

Ladies and gentlemen, welcome to this, the sixtieth edition of the Weekly Head Voices!

I know that I’m terribly late, so I imagine that you’ve probably missed my incoherent babbling. To try to make up for this, allow me to present you with this YouTube clip of me babbling almost coherently for 20 minutes! In week 41 I had the privilege of giving an invited talk to an audience of 100+ medical imaging geniuses at the yearly symposium of the Netherlands Forum for Biomedical Imaging in Leiden, and the whole thing was recorded by the artist formerly known as fpixel:

If you’re not into academic talks, I suggest the following YouTube clips as alternative entertainment: First, the new Avengers trailer resulted in the accute arrest of my teenage comic book fanboy heart. Besides all the superheroes (SUPERHEROES!) some Next Level Human Being (NLHB) opted for Nine Inch Nails as soundtrack! The previous time I gushed this much about a trailer, was with Iron Man 1 and their choice of Black Sabbath, and you of course remember how that turned out.

Second, do you remember that dude in the really terrible Police Academy movies who could make like a million sound effects WITH ONLY HIS MOUTH? His name is Michael Winslow, and with the following clip he has completely redeemed himself:

So now let’s get back to talking about me.

I grew up eating science fiction books for breakfast, lunch and dinner and dessert. I was one of those strange kids who used to read secretly under the covers (with the backlight I ripped off my microscope of course. yes, I owned a microscope you jock.) whilst I was supposed to sleep. Please try to imagine what it was like when I read last week that Virgin Galactic has just finished building Earth’s first commercial spaceport. People, we have our first frikking spaceport, you know, where spaceships take off and come to land!

We’re living in a science fiction novel.

Finally, Genetic Offspring #1 officially learnt how to tie her shoelaces on Tuesday, October 11, 2011. Genetic Offspring #2 started feeding herself four days after that. Now that’s amazing.
