What is meant by information in physics?
Information is a purely mathematical concept, usually a a characteristic of uncertainty (of a probability distribution function), but can be interpreted in different ways. Thus information is a difference of proper information (difference of negative entropy) of two states.
Why do we need physics?
The goal of physics is to understand how things work from first principles. Courses in physics reveal the mathematical beauty of the universe at scales ranging from subatomic to cosmological. Studying physics strengthens quantitative reasoning and problem solving skills that are valuable in areas beyond physics.
Why do we love physics?
Physics helps you to understand the world around you, and satisfy your curiosity. Studying physics develops your critical thinking and problem-solving skills. Physicists are versatile, which opens a wide range of future careers. Physics drives technology advancements, impacting society, the environment and the economy.
What is a good grade in physics?
I’d consider anything from 81–100% a good grade. But it’s also fine to include 71–80% there as not everyone is good at everything, nor should they be so.
