目の錯覚｜Optical Illusion｜2022/05/30

高知市にある科学技術館に行った。プリズムの光の屈折やテコの重さの原理などが実際に体感できる。小中学生のときにこんな施設があったらきっと理系になっていたかもしれない。そこに目の錯覚を利用した騙し絵があった。自分が移動すると絵が追いかけてくる。何度やっても同じだ。実は平面ではなく、立体に描かれた絵なのでそういう錯覚が生じるらしい。しかし一旦そのタネを知ると、今度はどう見ても単なる立体の絵にしか見えない。この展示はそこまでの学びを期待しているわけではないと思うけど、かなりの思い込みでしか見てない自分に愕然とした。（絵と文：サカキテツ朗）
I went to the Science Museum in Kochi City. We can actually experience the refraction of the light of the prism and the principle of the weight of the lever. If there was such a facility when I was in elementary and junior high school, I would have been in the sciences. There was a deception picture that used the optical illusion. When I move, the picture follows. It's the same no matter how many times I do it. Actually, it's not a plane, but a three-dimensional picture, so it seems that such an illusion occurs. However, once I know the structure, this time it looks like a mere three-dimensional picture. I don't think I'm expecting that much learning from this exhibition, but I was shocked to see it only with a great deal of conviction. -Text and illustration by Ted Sakaki
