# The calculation of the elevators is more difficult to calculate the flight to Mars

*Represent how difficult the super-higher mathematics of «lifting life», it is quite difficult for us. But if you scroll through many pages of multi-storey formulas of integrals in the new work of the professor of nonequilibrium statistical physics*

*Flying on Mars or calculation of the kinetics of a nuclear reactor — for us it is yes! We understand how difficult it is. But it turns out that «elevator life» (how many elevators, of which size and with which algorithms are needed, for example, for a 100-storey office building of a certain planning to ensure the maximum waiting time <x) is even more difficult.*

*And although engineers believe that they have developed computing models for the maximum realistic modeling of elevator systems, everyone knows that for some reason hell begins: a crowd of people in the lobby, the crowd when loading and unloading and unpredictable catastrophic waiting time.*

**New work is the first attempt to understand why this happens, and how it can be avoided (for example, designing the building upwards).**

*The study showed a complex nonlinear dynamics of the elevator system, when, with an increase in passenger traffic, the elevators begin to synchronize, creating traffic jams. Eliminate this is possible only when several elevators simultaneously return to the first floor. And this is just one of the problems, the number of which is avalanchely growing with the complication of the scheme of the floor distribution of the number of people working in the building and its visitors.*

**Many solutions here: the tricky ratio of the number of elevators and office space; elevator groups serving groups of floors, etc.**

**In short, the front of work is huge. And taking into account the pace of urbanization of the world, the problem turns out to be aware of the accuracy of interplanetary flights.**

*And in conclusion again about the main thing:*
