Scientific American "What Is 5G?"

           I read about 5G. 5G is a new telecommunicating system using very short radio spectrums. We can use this for many things. And it will make our lives more convenient.  First, there are various products embedded, such as sensors of vehicles medical machinery. They are connected by 5G, there is not any lag. So we can operate vehicles very precisely. Second, we can use sidelinking system. The Sidelinking system will allow self-driving cars to coordinate more efficiently by communicating with each other directly.  So we can prevent traffic jams.   

My favorite movie

            One movie that I really liked was "Sord Art Online Ordinal Scale." It was stered by Matuoka Yositugu, Kayano Mei and so on. It was made by A-1 Pictures. It was the story after main part of SAO.          The world of this movie is where AR technology greately advanced. Only by attaching a special small device on the head,  people can feel another world and move in the world. Especially, AR game Ordinal Scale was popular. In such a world, the incidents that the AR game player loses their memory about SAO. SAO is a VR game that the protagonist and his friends played. The protagonist fought in the AR game.          There were many impressive battle scenes. And the bond between characters is feeling. Please try it.  

A Picture of Cardbord Boat Race

イメージ
           There are two children in a boat made of cardbord in a pool. The one girl looks dissapointed, but the other girl is smailing. They are paticipating in a competition.          The cardbord boat was made by them. It has a roof and a flag made of cardbord. It also have colorful decoration with color tapes. The boat surprisingly floats them on the water. But their boat are so late compared with other boats. They should make bigger awls.      https://www.nytimes.com/column/learning-whats-going-on-in-this-picture

psycology lecture 10/26

           Today's psycology lecture was about boubakiki effect and human memory. Boubakiki effect was general in the almost of all languages, and interesting. Memory has several parts and aspects.          Boubakiki effect was relation between figure and orditory. There is a very famous experiment. There are two figure. One has many needles like sea urchin and the other is like clouds. If you bring them name Bouba or Kiki, which do you choice? many people will name the former kiki and the latter bouba. This tendency is present all over the world. Human tends to connect "K and  T" with "needle and solid" and connect "O and A" with circle and orbitat. This is ubiquitus in any culture, language and place. It was interesting.          Memory is devided into long term memory and short time memory. The former is called "working memory". This is known for many people. But we hadn't know how human remember thi...

EN speaker's YouTube Live stream

           Today, I tried English YouTube Live. That was made for English beginer, so speaker spoke easy English slowly. There were some slungs about eating introduced with some examples. The speaker like Japanese culture and the speaking was fun!          There were a couple of slungs about one meaning. She tought "Yummy" and "Tasty as hell". I could'nt understand what they mean. In fact, they mean "delicious". She used this, for example, by saying "lemon ramen is Yummy". I was surprised at "lemon ramen". What is lemon ramen? It was hot or cool? That was the original one in foreign countries?           I learned such English slungs. I also enjoyed funny talking simultaniously. I want to listen more. I state other slungs below.             "Yummy"  "I could eat a horse"  "Let's dig in"  "Tasty as hell"  "Pig out" "seconds please"  "i've go...

Today's phisycs lecture

          Today's lecture was about potential energy and kynatic energy. These were fundamental things, but there were hidden relations between some equaations. And all of these principles are based on the most significant principle, which is called "Newton's kynatic principle".          The lectere began the calculation of vectors. "What will we get if we multiplicate vecors each other." We ordinary respond "we will get vector". Is this right? In fact, wether this is right or not depends on how we define that multipulation. For example, if we define we will get scholar, we will get scholar. However, this is not relevant with today's lecture.          Firstly, we defined the potential energy. It was easy. We only have to change the "work" into "energy" by replace work's facter, power, into gravity. It means that potential energy is multipulation of gravity and distance.          Seco...
