An anti-gravity kitty called Newton

Quite a lot of time passed since my last post. Seriously, this time, I wasn't lazy, but too busy.

Just kiddin', I played final fantasy and read comics..

Anyway, let's not waste the precious reader's time. Right to the point of this post, namely science and why we actually believe in it *. Actually, all the noise is only due to this quote I wanted to share at any cost, just because it summarises my feelings about the future of humanity thanks to science:

"The oil will never run out. It's not because we have a lot of it. It's not because we'll gonna build a billion windmills. It's because, well, thousands of years ago people had ideas, inventions, technology and the stone age ended. Not because we ran out of stones… "

Richard Sears "Planning for the end of oil" TED

not asking the right question

"The question is not whether intelligent machines can have any emotions, but whether machines can be intelligent without any emotions." (Marvin Minsky)

penguins and ostriches

"It's not bad to start with "Birds can fly." and later change it into "birds can fly, unless they are penguins or ostriches". But if you continue to seek perfection, your rules will turn into monstrosities:

Birds can fly, unless they are penguins or ostriches, or if they happen to be dead, or have broken wings, or are confined to cages, or have their feet stuck in cement, or have undergone experiences so dreadful, as to render them incapable of flight.

Unless we treat exceptions separately, they'll wreck all the generalizations we may try to make. 

We almost never find rules that have no exceptions- except in certain special artificial worlds that we ourselves create by making up their rules and regulations to begin with. Artificial realms like mathematics and theology are built from the start to be devoid of interesting inconsistency. But we must be careful not to mistake our own inventions for natural phenomena we have discovered. To insist on perfect laws in real life is to risk not finding any laws at all."

Nonsense

It seems that I have lots of spare time recently. :) I'm still waiting for the Stanford University open courses to start. That will take awhile..

But now for something completely different... I might have mentioned about the "Society of Mind" lectures. In one of them, Minsky started to explain theories about "Why jokes are funny?". According to the mighty Freud, jokes are funny, because they are messing with "not allowed" topics. Things our society try to suppress thinking or talking of, like violence, sex, bad politics, etc.. So our mind is trying to mask our real thoughts by making them seem not serious. And you might say, "Ye, Freud, the guy is nuts!", but I find it reasonable explanation for the majority of the jokes. And here's the funny part, Freud's theory does not explain why the nonsensical jokes are also funny. Does it?

Think about it for a moment. Why are nonsense jokes funny? This is extremely interesting question for me, because I'm a big big fan of Monty Python, and the jokes there are totally nonsensical. It's like a surrealism without the depri-art part. So I needed to know why people are laughing like crazy when they hear a punchline that's completely illogical and sometimes not related to the rest of the joke.

The answer is here. In this wonderful paper, Minsky suggests that the reason people laugh when hearing nonsense jokes is the same as the reason they laugh about all other kinds of jokes . And this reason was originally formulated by Freud - they allow our childish consciousness to play with forbidden things. This time, the forbidden topic is logic, or more precisely, the lack of it. Illogical thinking is considered bad thing in our society and the people speaking nonsense are labeled dumb. Of course, not if you are telling jokes ;) .

And now for something completely the same: a fine selection of toys for your mind I found around the web:

Driving down a road Santa sees a sign that says, “Watch for Fallen Rocks.” A few kilometres later, he sees some rocks at the side of the road, so he stops and picks them up. When he gets to the next town, he carries the rocks into the Highway Maintenance office and puts them on the counter. “Here are your fallen rocks,” he says to the man behind the counter. “Now where is my watch?”.

These here are from the paper:

A gentleman entered a pastry-cook's shop and ordered a cake; but he soon brought it back and asked for a glass of liqueur instead. He drank it and began to leave without having paid. The proprietor detained him. "You've not paid for the liqueur." "But I gave you the cake in exchange for it." "You didn't pay for that either." "But I hadn't eaten it".

--- from Freud (1905).

Well, some of them are not complete nonsense, see.. But they are in the same category, since they make fun of false interpretations. (Btw, if you have more, please share! :)
