量子力学

Quantum Matter

科学についてのビデオを元にした英会話レッスンです。「量子力学」についての物です。この分野の研究はとても高度です。なので、細かな詳細のすべてについては理解する必要もありませんが、ビジュアルがとても素晴らしいので、このビデオを題材に、講師と英会話してみて下さい。

Introduction

Watch the short video before class (five minutes). Make any notes on any language you don't understand. It is OK if you don't understand all of the science! Note that you can turn the subtitles on via the "settings" button.

This is a good discussion topic, because not everything in quantum mechanics has an answer or is understood, so you can share your opinion with your teacher!
 

Warm Up

Have you heard of quantum mechanics (also known as "quantum physics" or "quantum theory") before? Tell your teacher. 

After watching the video, what does the double slit experiment tell us?

Language

Work through the following tasks with your teacher.

Language check

Do you have any questions about the language used?

SUMMARY:

What is the video about? Use natural conversational English, like:  "I saw this interesting video yesterday..."

Comprehension

Answer these questions:

  1. What happens when marbles are shot at the slit(s) in the wall?
  2. What happens when electrons are shot at the slit(s) in the wall?
Paraphrase

Try to put this sentence in other words:

"The very act of measuring (or observing) which slit it went through, meant it only went through one, not both."

Practice

Do you think the following conclusion can be made?

Things only exist because we observe them. Otherwise they only exist as a probability. We create the universe by observing it.

Discuss this topic with your teacher.
