無駄のないスピードで論理をおっていけるので聞いていて理解しやすいです。 この話が疎外(阻害)されない場所が東大だと思うと勉強頑張ろうと思えます。 居酒屋で酔っぱらっている人とかのスピードに合わせるのは苦痛です。

小学校の頃から箔検電器は問題でよく見たのに実物をこの動画で初めて見た。高校物理の原子分野とも結びついて面白い授業でした。

Movement from the inside of a wall to the outside of a wall in a space-time that is physically impossible in everyday life. I don't have the feeling of asking time and space, so I'm arranging letters without knowing anything about science as a phenomenon brought about. 壁の内側での時間の経過を左から右への線で表しています。━ 移動の方向←→とその時間―として表しています。 ⇦⇨は視線の方向であり身体の向きです。 ①②③ は時間の推移です。 ━━━━━━━A━━━━━━━━━━C━━ ―――― ←⇨① →⇨③ 壁の外側での時間の経過です B┅┅┅┅b ←⇨② A B a b は移動の起点です C は記憶が現れた時点として表しています A = B A ≠ B Movies sometimes seem to me like texts about space-time, out of fiction. The hero who acts while time is stopped. However, I have a desire to read what kind of letters are arranged in science books about the passage of time while the main character acts. The story of a young man who can teleport. I don' t think there was any explanation for teleportation in the movie. I have a disappointing feeling. When I returned from the space-time outside the wall to the time and space inside the wall, I had no movement. I wonder why. Curiously, I wonder if the time and space inside the wall seemed to me like a different dimension. Time to stop, and teleportation. I also wonder if it was because I was in a space-time where the second hand of the clock wasn't moving yet. I'm curious about the short time while standing and what makes the move start. I don't know science, and I wonder if it's gravity or the second hand of the clock is waiting. Humans are mysterious. I don't think the position that space-time captured me was wrong. I am moving to that position. Of course, I have no idea how to move. It is a certain feeling that my body does not move. Maybe some of you have the same feelings as I did after watching the movie. The four-sided clock in Ginza has stopped moving. Many people walking are stuck. Cars too. Among them, I go down the stairs to the subway. What kind of space is it? Why did the hero's youth learn to teleport? If space -time is the phenomenon that he brought to him, what should he learn in space-time? American movie, title in Japan, The Matrix. Just. Time to stop, teleportation, and events brought about by space-time. Or, instead of confronting or challenging space-time, I want to work and learn in a laboratory or academic place where space-time is studied as a human body. PAGE . 2 / Part 3

内容は物凄く面白かったんだけど、この手の講演者の人たちって、この人はまだマシだけど、なんでこんな早口なんだろうか。しょっちゅう「どもる」し。聞きにくいったらありゃしない。公演時間が限られてて急いで話してるとか 何か事情があるのかな? もうちょっと落ち着いてゆっくりしゃべってくれよと思うわ
