Recently, I've been learning physics through an online course.
My family usually learns about the universe. Whenever we meet, they always talk about the physics of universe.
It was difficult and I find it hard to join in the conversation.
I asked myself. "Can I enjoy our time together?"
That's the reason I started learning physics. (It's special relativity)
I haven't been good at physics and mathematics since I was a student.
I thought that when I see the amount of mathematics involved, I may lethargic/tired.
It was quite difficult, but I was inspired by the view of the world.
The logic is mysterious.
For example, if one person moves fast, time becomes slow.
He gains more time.
It's difficult for me to understand, but the logic makes sense.
