Scrodinger's Cat

The 3rd and 4th classes were Schrodinger’s cat class. We learn atoms and read Schrodinger’s cat book. Atoms are very interesting. Schrodinger’s cat is related to protons and atoms. No one knows what happened to the cat in the iron. Until we see it. Schrodinger’s cat book is funny, but the story is difficult. We read the contents of another chapter. After that, I had free time. I could learn more delicate science.
