Life with Fluctuations

Have you ever gazed intently at the flickering flames of a candle or bonfire, and felt yourself grow calm and relaxed? The flames flare brightly, then recede; they wave long and slow, then suddenly quiver in short, rapid bursts... In fact, flames exhibit a very special flickering pattern called “1/f fluctuation” that gives a feeling of peace and comfort to humans. The babbling of a brook, a gentle breeze, the chirping of little birds--all soothing natural phenomena exhibit this unsteady 1/f fluctuation. Why does 1/f fluctuation make people feel calm? It turns out that we humans also possess 1/f fluctuation in many ways: heart beats, eye movements, changes in body temperature, and brain waves all exhibit 1/f fluctuation. The precise details are not quite understood yet, but it is believed that 1/f fluctuation is soothing because it is also present in our biological rhythms. In addition to natural phenomena, 1/f fluctuation has also been discovered in classical music and traditional artwork. It is a bit curious that people derive comfort and pleasure from instability.

Fluctuations (constant change or vacillations) exist in many of the natural phenomena encountered in daily life, and they have been used in the development of devices that make people feel cozy and comfortable. Have you ever seen an electric fan for sale that has a 1/f fluctuation button? This was previously devised by Professor Masahiro Agu, the expert in this field. 1/f fluctuations are now in use in coolers and various types of therapeutic products.

Electric fan, cooler.

By introducing 1/f fluctuations into daily life, you can experience the atmosphere of the highlands or the forest while never stepping outside of your room in the middle of the city. For example, the Japanese highlands of Kiyosato or Karuizawa, or the forests of Yakushima could be used as sites to collect data on fluctuations in wind speed and direction, and in amount of available sunlight. This data could then be used to create natural fluctuations in the artificial wind and light of electric fans and light bulbs, allowing us to faithfully reproduce a natural breeze or sunshine filtered through leaves.
