Imagine, dude creates an article with the following text: "A sandwich always drops butter down."

in a week, the article looks like: “A sandwich - a piece of bread, buttered with butter, always falls with the buttered side down. The reason, the trend, the hidden properties. "
')
in a year: “Sandwich theorem. The sandwich always falls with the buttered side down. Being dumped perfectly vertically, a sandwich with butter can fall equally on one side or the other (in fact, sandwiches fell more often onto the non-oil side, since in the process of spreading with oil they acquired a slightly curved shape). However, if you push a sandwich from the edge of the table (a typical household situation), then it usually makes a half turn in the air and drops it down with oil. This theory can be calculated using the formula: the square of the angular velocity of rotation is equal to the product of the private between six times the weight of the sandwich and half its length by the width divided by the sum of one and three times the square of the sandwich.
