Groups in mathematics are the most common in our lives. No matter what we want to do, as long as we use cash, we will use calculations in mathematics, which is inseparable from everyone in our lives. We often find that some people lift heavy things and can't get up by themselves, so they will pry them up with a stick and let others move smoothly. These are all scientific explanations based on the lever principle in physics.
In our daily life, we often find that when decorating a house, some people will use a wheel with two wires around it because the house is relatively high, and then move it from bottom to top, which saves physics and manpower. This convenient way also uses the principle of crown block and moving pulley in our physics, which can shorten our distance by half and our effort by half, and will also provide us with a good one. Then when we arrived at a strange place, we couldn't tell the direction here. We will also learn something about watching the sun or clouds in the process of learning geography to identify the direction of our place.
In our language, we will learn some rhetorical devices, such as metaphor. Although we may not think hard about what we are saying in our life, we will also use these rhetorical devices inadvertently, which can make others feel that what we say is very deep and that we are a very cultured person.
