Learning Partner: What would you like to teach me today?You: How about probabilities?Learning Partner: I'd love to. I'd love to hear your most basic understanding of probability - what does it mean and what are its partsYou: Probability simply measures how likely something is to happen. The probability of an event is a number between 0 and 1. A probability of 0 indicates that the event is impossible while a probability of 1 indicates certainty. The higher the probability of an event, the more likely it is that the event will occur.Learning Partner: Interesting, can you give me a specific example?You: Sure! The best example for understanding probability is flipping a coin. There are two possible outcomes — heads or tails. When the coin is fair, both outcomes have equal probability. We write this as P(heads) = P(tail) = 0.5.Learning Partner: Is there a way to estimate the probability of a specific event?You: Yes, you can simulate multiple trials and count how often the event of interest occurred. P(event) = #{number of times it occurred} / #{number of trials}.Learning Partner: What else is there to know about probabilities?You: A lot! One notable thing is that probabilities sum to 1 when you are dealing with mutually exclusive events that encompass all possible outcomes.Learning Partner: What would you like to teach me today?You: How about classical mechanics?Learning Partner: I took mechanics in school but don’t remember much. I'd love a refresher. What is classical mechanics about?You: Classical mechanics is the theory of how an object moves when it is subjected to various forces.Learning Partner: Interesting, what is it used for?You: It makes it possible to predict how an object will move in the future, and how it moved in the past. Learning Partner: What would you like to teach me today?You: I just learned about how the respiratory system works.Learning Partner: Oh yeah? Tell me about it!You: The respiratory system is the network of organs and tissues that help you breathe.Learning Partner: What does it mean to breathe concretely?You: Breathing is the process of moving air into and from the lungs to facilitate gas exchange with the internal environment, mostly to inhale oxygen and exhale carbon dioxide.
