Defterlerdeki Kırmızı Çizginin Sebebi!

Since elementary school, we've all known that red line on the left (or around) of our notebooks as a "leave for the teacher to take notes" or "leave for staples." But what if we told you that this line was invented centuries ago as an "insurance" against rodents that invaded our homes? In this episode, my guests and I delve into the history of paper and brainstorm to figure out how the "margin" was actually designed to prevent mice from eating information. The answer is far more interesting than you might think! #History #InterestingFacts #Education #School #Paper #Inventions #Brainstorming #GeneralKnowledge English Channel:    / @salihcantekin   Superpeer: https://superpeer.com/salihcantekin To Subscribe: https://bit.ly/3kvj2vw Github: https://github.com/salihcantekin Discord:   / discord   For membership:    / techbuddytr
