Christmas, Christmas Eve, Christmas. Physicists have calculated what prompted St. Santa to fly

For Santa’s sleigh to stay in a level ride, its weight must be balanced by lifting. This is due to the lower pressure of the air flowing over the wing from above than the pressure of the air flowing below the wing. Taking into account the weight of the sleigh and fairings, it must run at 19,800 km/h to create enough lift. The engine that accelerates the sled to that speed and overcomes air resistance must have a thrust of 38 million Newtons. That’s the equivalent of one engine on the Saturn V rocket used by NASA in the Apollo and Skylab programs.

The Journal of Physics Special Topics allows physics students at Leicester to learn about the process of writing and reviewing scientific papers. And although the articles published in it often concern trivial or entertaining issues, in writing them and reviewing the work of their colleagues, students act according to the accepted rules of the world of science.

“The process students go through mimics the process of publishing the work of real research physicists working on exciting topics such as black holes or curing cancer,” Professor Mervyn Roy, director of education in Leicester’s Department of Physics and Astronomy, told Mail Online. – We must study and approach new problems creatively, but also present our discoveries clearly, and check results by other scientists as part of the review process – explains the idea of ​​physics students writing works about Santa Claus.
