I just received a copy of a very interesting study made by three Universities in the United Kingdom on colour perception.
They found a tribe in Africa with a language limited to three words to describe colours. One word for the dark colours, one for middle range colours and one for very light colours.
To make a long a story short, in one of these studies, they showed different illustrations with different shades of the same colour to members of that tribe and they immediately identified the two shades that had a slight difference. But, when they showed the same illustration to westerners, who did not have different words to define those shades of green, they could not find the difference or took a long time to notice it. They haven´t got different words to describe those colours, therefore those westerners couldn’t find the difference so easily.
But when the scientist showed an illustration with six green squares and one blue square, westerners immediately pointed at the blue square, but people from that tribe couldn’t find it. They have the same word to describe both colours. For them the concept was the same and as colours are concepts we create in our minds, they could not find the difference. Continue reading →
I was watching a video of my daughter dancing, in my opinion, (and I must say that I am not the typical father who sees everything his children do as marvellous and perfect), she did a very good job, but for her, she danced terribly, I tried to see the terrible parts in it, to comment with her what should be improved, but it was not as bad as she saw herself.
That reminded me when I was her age I used to see the videos of my tournaments and I was extremely critic of myself. My teachers were happy with my improvements, but to my eyes I was really lousy and clumsy in my movements. Maybe it was the little critic we all have inside? Continue reading →
I was feeling calmed and relaxed as usual when suddenly I found a friend whose favourite hobby is watching the news channel. In just five minutes into the conversation he had given me the main headlines of the day and they were all appalling, bad news about tragedies, accidents, frauds, assassinations and so on.
I was amazed of the amount of terrible incidents in just one night, and how my friend was able to update me with the last news in just a few minutes. When he finished his “report” I asked him the practical application of that knowledge. I swear I didn’t ask that in with a bad intention. I was just surprised with his “eagerness” to learn every detail of every note, I haven’t met anyone with a better memory for details than him. Not even in my years into the radio and TV business.

One of the main problems Quantum Theory has been facing since its beginnings is that it goes against too many concepts and bases of traditional physics.
The old school of physics is always measuring everything it can, to admit it. As long as they can measure the phenomena, then it exists. But they have been encountering many events they cannot explain with their traditional baggage of knowledge. So they need to invent work theories to try to find new answers or new paths that lead them to those new answers and then is when things get very complicated. Continue reading →
