Φυσική Επιλογή και Εσύ – σε 3 λεπτά
Αυτή είναι η τρίλεπτη παρουσίασή μου από τον προκριματικό γύρο του διαγωνισμού Famelab, το 2010. Παρ’ότι κατάφερα να εντυπωσιάσω την κριτική επιτροπή, δεν εμφανίστηκα ποτέ στον τελικό γιατί δε με άφηναν να βγω από το στρατόπεδο νεοσυλλέκτων. Αν σας άρεσε η παρουσίαση για το ουράνιο τόξο, αυτή είναι πολύ, πολύ καλύτερη. Και στα ελληνικά!
Το κομμάτι για τα ελάφια είναι δανεισμένο από Douglas Adams (μία ομιλία που έχω λινκάρει σ’αυτό το blog σε τουλάχιστον 3 διαφορετικές περιστάσεις). Μ’επηρέασε επίσης ένα άρθρο με τίτλο Human Evolution Has Stalled το οποίο, παρ’ότι αρκετά προκλητικό, θέτει μερικές ενδιαφέρουσες ιδέες. Κυριότερη εξ’αυτών η ιδέα πως η σημερινή κοινωνία περιθάλπει δύο αντίθετες μεταξύ τους απόψεις:
1. Είναι λάθος να προσπαθούμε να δημιουργήσουμε καλύτερους ανθρώπους μέσω της επιλεκτικής αναπαραγωγής, της υποχρεωτικής στείρωσης, της γενετικής τροποποίησης ή οποιασδήποτε άλλης μορφής ευγονικής. (Δεν πρέπει να το παίζουμε θεοί).
2. Γενετικά κατώτεροι άνθρωποι που σίγουρα θα πεθαίνανε αν έπρεπε να βασιστούν αποκλειστικά στις δικές τους δυνάμεις, πρέπει να εξοπλιστούν με κάθε βοήθεια ώστε να επιβιώσουν, και έχουν δικαίωμα στην αναπαραγωγή. (Πρέπει να το παίζουμε θεοί).
Θέλω επίσης να ευχαριστήσω τον πολύ καλό μου φίλο Δημήτρη Πλεξίδα για την ανεκτίμητη βοήθειά του στην επιλογή θέματος και στο brainstorming της ιδέας. Ευχαριστώ επίσης τον Παναγιώτη Θεολόγου που ξέθαψε το βίντεο ολόκληρης της εκδήλωσης, για την ύπαρξη του οποίου δεν είχα ιδέα.

Color Vision, Diet Advice and How Rainbows Work: a 3 minute (or so) presentation

I was about to post my FameLab presentation on human evolution when I realised I had never blogged my video on how rainbows work.
I took part in the preliminaries of the Greek FameLab competition in 2010 and made it to the finals, but never got the chance to compete because the Greek Army wouldn’t let me out of boot camp. FameLab is an international science communication competition. The participants are supposed to present a scientific subject in a clear, concise, and entertaining manner, in under 3 minutes.
I had the opportunity, along with the rest of the Greek finalists, to take part in a workshop on science communication and media skills. As part of the workshop, we were supposed to prepare a 3 minute presentation on one of the following subjects:
1. What makes pop corn pop?
2. What causes a rainbow?
3. Why do leaves change colour in autumn?
4. Why do I feel dizzy when I spin?
5. What are stem cells?
6. Why do some people have brown eyes – or blue?
7. What is the difference between bacteria and viruses?
None of these subjects are particularly fascinating to me. In the end, I picked rainbows, hoping to talk about colors and vision and xkcd’s fascinating color survey. Unfortunately, it turns out there’s only so much you can fit into 3 minutes, all while trying to explain a phenomenon that is not, in fact, as simple as saying “refraction”. Thanks to the internet, this can now be remedied. Here’s the text of the presentation I wanted to give, followed by the video of the actual one, right after the jump.
Influences and process
Sometimes (or even most of the time) I use my blog to collect things I don’t want to forget. As an archive for things I know I’ll want to find again, someday.
This is one of those times.
I read this fantastic article on Comix Cube, a while ago. It talks about work ethic and motivation and the fundamental drive that leads us to create art. It blew my mind (that happens a lot, lately…)
You ask whether your verses are any good. You ask me. You have asked others before this. You send them to magazines. You compare them with other poems, and you are upset when certain editors reject your work. Now (since you have said you want my advice) I beg you to stop doing that sort of thing. You are looking outside, and that is what you should most avoid right now. No one can advise or help you – no one. There is only one thing you should do. Go into yourself. Find out the reason that commands you to write; see whether it has spread its roots into the very depths of your heart; confess to yourself whether you would have to die if you were forbidden to write. This most of all: ask yourself in the most silent hour of your night: must I write? Dig into yourself for a deep answer. And if this answer rings out in assent, if you meet this solemn question with a strong, simple “I must”, then build your life in accordance with this necessity; your whole life, even into its humblest and most indifferent hour, must become a sign and witness to this impulse [Rilke. Letters to a Young Poet, Letter One].

On worship
I’m thinking about this and going crazy:
In the day-to-day trenches of adult life, there is actually no such thing as atheism. There is no such thing as not worshipping. Everybody worships. The only choice we get is what to worship. And a compelling reason for maybe choosing some sort of God or spiritual-type thing to worship — be it J.C. or Allah, be it Yahweh or the Wiccan mother-goddess or the Four Noble Truths or some inviolable set of ethical principles — is that pretty much anything else you worship will eat you alive. If you worship money and things — if they are where you tap real meaning in life — then you will never have enough. Never feel you have enough. It’s the truth. Worship your own body and beauty and sexual allure and you will always feel ugly, and when time and age start showing, you will die a million deaths before they finally plant you. On one level, we all know this stuff already — it’s been codified as myths, proverbs, clichés, epigrams, parables: the skeleton of every great story. The whole trick is keeping the truth up-front in daily consciousness. Worship power — you will end up feeling weak and afraid, and you will need ever more power over others to numb you to your own fear. Worship your intellect, being seen as smart — you will end up feeling stupid, a fraud, always on the verge of being found out. But the insidious thing about these forms of worship is not that they’re evil or sinful, it’s that they’re unconscious.

Update: I was pointed towards the original, unedited speech (thanks sis!) and corrected the quote above to reflect it. You can also find a (more or less accurate) transcript of the entire thing over here.

Magic For Real
Kary Novel and I visited Alexia Amvrazi at the Athens International Radio last Friday, to be interviewed on her show, Athens4Real. Aside from interviewing us on air, she was also kind enough to shoot a short video promo. Which I’m posting here.
Learn magic with Kary Novel and me! Join the fun!
See us perform at the Comedy Nights! Wednesday to Sunday at 22:00, Aiolou 48-50, Monastiraki.
Does Your Language Shape How You Think?
Ever wonder how English ended up as this planet’s “International Language”?
If you’re Greek, then you’ve probably heard about the vote that happened some time during the last century to decide which language would be used for international affairs, business, signage and so on. According to the story, Greek lost to English by just one vote. In fact, the especially dramatic version says that, while everyone was voting, one last grecophile was in the toilet.
So close!
Of course, the whole story is bullshit.
It looks like this is New York Times Week, because I’m linking to another great article I read over there. Does Your Language Shape How You Think talks about, well, how language shapes the way we think. It’s a fascinating piece.
Among other things, it compares languages that assign genders to inanimate objects (French, German or Greek for example: le pont, die brücke, η γέφυρα) and languages that don’t (the bridge).
I like English. It’s concise, easy to learn and constantly evolving. It’s also often ambiguous, very context-sensitive and has tons of homophones. Which is great for comedy.
I don’t mind it being the “International Language”. In fact, I would argue that it might be better suited for a modern, civilized world than many others. A language that doesn’t discriminate between, say, a male or female teacher is much better suited to a society where people of both genders (and everything in between) are considered equal.
Of course, language is, possibly, the least of our problems, but it’s an interesting thought.
Anyway, read for yourselves, and let me know what you think.

What Is It About 20-Somethings?
Are you 20-something?
Do you ever wonder why you don’t feel like an “adult” yet?
Does it seem like “real” adults expect you to be one?
Are you clueless as to what you want to do with your life?
Of course you are.
The reason I know this, is that I know all the people who read this blog personally…
According to this NYT article, we’re going through “emerging adulthood”. Some psychologists are trying to establish it as a new stage in human development. Its main characteristics include “pervasive ambivalence towards self and society,” “the feeling of absolute freedom, of living in a world of pure possibilities” and “the enormous value placed upon change, transformation and movement“.
So it’s basically a second adolescence for spoiled, rich kids.
Here’s another great quote from the article: “The 20s are like the stem cell of human development“.
Go ahead and read it (it’s pretty long) then come back. I’m not going anywhere (after all… I’m in the army).
I’ll be the first to admit that I’m displaying all the signs of “emerging adulthood”. I’m also the last person to say no to any excuse for postponing maturity.
But I often wonder: how much is too much. How long can I afford to keep searching? Is there a cut-off age? A time when you decide that your dreams (whatever they may be) are no longer a possibility? Is it thirty? And, anyway, what are you going to do about it?
I’d love to hear your thoughts.
How To Be Alone
I’m posting this here, almost as a reminder to myself…
