Think of a situation where "particle motion" is a blessing in disguise for the entire humanity.

The concept of particle motion, not just a "blessing in disguise" but a significant concept in which humanity must learn about. The theory of particle motion simply states that "the particles which comprise matter, are constantly moving." For example in the application of aerosol sprays, particle motion is important because the aerosol particles would constantly disperse instead of being in a single position.
