Brownian movement under close observation The slightest trembling can tell us something. Tiny particles, dissolved in liquid, register what is going on in their surroundings, and react as a result. Without sophisticated measuring techniques and high precision instruments it is impossible to decode how their messages work. However, if successful, amazing discoveries await decryption experts.
