Awful design decisions

Our new candidate for awful design decisions of the decade is especially intriguing. I was going out in the kitchen to make some food. I wanted to make the refrigerator a bit colder because some stuff was getting spoilt. Inside the fridge I got presented with this control panel..




Should I go towards the min saying I want to minimize the temperature, or should I go towards the max saying I want to maximize the power output? This simple task had become so ambiguous that I had to look up the manual. Seriously, the guys at Daewoo don't expect that anyone could just set the inner temperature of the fridge easily and seamlessly... So here's what it said in the manual.




 Here's what it says in a different manual, published by Daewoo.



Now that's great. It very well explains that by default the middle leds is shown then after that, the led at position 4 is lit up and it goes on to describe the cycle order... All right, perhaps just pushing the buttons repeatedly is not enough for some monkeys, but what do I do with this utterly useless information? Wait, it goes on and explains the same thing again! And most of all, how do I make the inner tempreture colder? Disaster...

In my last despair, I decided that in order to get the answer to my question, I had to think like a Daewoo designer and walk in their shoes. What could he have thought? Hmm. FRZ. TEMP, REF. TEMP MIN MAX... Aha, maybe temperature means the actual temperature? But then again there's no unit measures, like C or F, just numbers. So perhaps, if I set temp to min, logically it would mean minimum refrigerator temperature. So that must be it.

I wasn't convinced so I decided the search the internet to find the ultimate answer to this incredibly difficult task. In other model manuals, guess what. They had the same stupid descriptions. However, in more advanced models, they improved and decided to put a C mark. So you know what? It turns out that actually, it is MAX that means lower temperature, though I'm still not sure. I would have never thought that Daewoo would make my life easier. They didn't.

What alien life might look like?

Yesterday, I was thinking what life is. Then I saw a TED video by David Deutsch, who called life a "chemical scum". And he's so right. I mean imagine an alien who has never seen life before. What does he see? He sees molecules. Molecules sometimes form planets, sometimes they merge or split releasing energy, for example in a star. So what does he see when he comes to the Earth? He sees molecules that interact with eachother in the limits of the Laws of Physics. Phisics is what defines what is permitted in our Universe. So basicaly what this alien sees is some molecules who interact with eachother in an uncommon way, not like for example molecules on a rock. Even if you think of humans and human society. That is no different to grass or lifeless objects, in that it is just a bunch of atoms that in the limits of phisicys, at this point in space, at this time, interact with eachother in a way, that it creates a thing that is collectively know as humanity.

So what is my point. My point is that when we search for extraterrestrial life forms, they may be fundamentally different than us. That is they may not even be lifelike, it could be the case that there is another cube of space at this time, where the laws of phisics make molecules, and energy interact with eachother in a way that it creates some totally wierd, outlandish phenomenon, that we can't even imagine now. Life is no different than a black hole, in that it is just a phenomenon that under certain conditions with some probability, exists. It's just one property of the Universe and what physics allow.
