There is a popular meme with a smiling woman and the caption says: "When you meet another physics Ph.D. and they also hate their life". While it is a joke, there is some truth to it. The concepts of physics are difficult to understand. Not everyone is capable of doing it. You need to have a specific view of the world and the way it is designed. Therefore, physics memes are great when you need to switch your mind from the long and complex formulas to something more relaxing. The best part is that there is always a meme you can relate to and feel yourself a part of the community.
