Christmas: Physics explains the journey of Santa Claus | El Comercio Peru – Trade

A astrophysics at the University of Maryland, in the United States has an interesting series of calculations to determine how Santa could make the giving of gifts to all children who behaved well during the Christmas night.

The mythical journey is obviously impossible to be performed by a human being, how many children, how heavy the load and the limitations imposed on us over time.

Still, the flight imaginary, for Astrophysics Linda Harden starts by defining some variables. Only takes into account children who celebrate Christmas, hence the equation Christian children are considered only . This means that Santa must deliver presents to 370 million children (according to the census of Population Reference Bureau) within a time limit of 31 hours, given the different time zones.

FAST AND HEAVY

This leaves the bearded the only option make 822.6 visits per second to be on time for each household before the end of Christmas.

The gifts together weigh about 353 430 tonnes (without the weight of the sleigh), a similar load weight Empire State, emblematic building in New York, and could only transport a herd of 214,000 reindeer sleigh to mobilize 650 kilometers per hour.

DATA

For the study it was found that an average of 3.5 children per family. So, would be 91.8 million households for visiting.
