Math for Bump (ing)?

I accidentally searched the FAQ for bu.mp ( http://bu.mp/faq ), and this part caught my attention:

Q: No way. What if someone else is facing at the same time?

Way. We use various methods to limit the pool of potential matches, including location information and characteristics of the shock wave event. If you come across especially (for example, at a conference) and we cannot solve a unique match after one hit, we will just ask you to hit again. Our CTO has a PhD degree in Quantum Mechanics and can show the math behind it, but we suggest downloading Bump and trying it yourself!

Is there any reason why some kind of non-trivial math may arise behind the blow, or "Our technical director has a doctorate in quantum mechanics and can show the math behind it", maybe this is just a little ordinary language? [Itโ€™s hard for me to imagine why something more complicated is needed than looking at location + time, but maybe I just underestimate the problem or the types of data that the iPhone could collect from being hit (for example, some form of tremor ?).]

I sincerely doubt that mathematics is too complicated in them. It simply corresponds to โ€œbumpsโ€ that occur within a very short period of time in a specific area.

If there is more than one match over a given period of time, within that area he will probably ask you to pounce again.

The joke comes from:

One of the most shocking facts of quantum mechanics, first obtained by Werner Hiesemberg, is that operators do not always commute. There are many different formulations and interpretations of this fact, for example, the "principle of uncertainty."

What can be interpreted as:

"If you measure the linear momentum (mass * speed) of something with high accuracy, you cannot do the same with its position."

This effect and interpretation were the subject of tests, perhaps the most famous were those that were carried out by Einstein (experiments with gedanken), some were refuted by Niels Bohr.

In order to be able to observe the effect, the mass involved must, of course, be very small, therefore it is โ€œvisibleโ€ only to subatomic particles, never for something as large as the iPhone.

Similar inequalities hold for other conjugate operators, such as time and energy.

Everything is much more complicated when the general theory of relativity is taken into account (for example, think, for example, in the concept of "time"), and I think this is the idea of โ€‹โ€‹the phrase "Our technical director has a PhD thesis in quantum mechanics and can show the mathematics behind."

To clarify: IF the iPhone should exhibit quantum mechanics, then Bump would not be able to pair (position and speed, time and acceleration) phones trying to "pounce" on
