# gst: when and how a levitating droplet sings (as a pipe)

<< Sprinkle water onto a very hot pan, and you may notice that the droplets evaporate surprisingly slowly. They stick around because of what’s called the Leidenfrost effect—a thin layer of vapor forms between the droplets and the hot surface, insulating them from the heat, and keeping them from boiling off immediately. (..) droplets of water in this Leidenfrost regime emit periodic sounds, or beats.  >>️

<< While emitting sounds, the droplets oscillated as pulsing stars whose points moved radially in and out. (..) this vapor-layer frequency matched the period of the beats, and (AA) therefore concluded that vapor escaping from beneath the droplet was responsible for producing the periodic sounds. >>️

<< the frequency of the sounds made by a droplet depended on the droplet’s size—following the model of an organ pipe, whose tone depends on the velocity of sound and the length of the pipe. This implies that the sound production mechanism in a Leidenfrost droplet is similar to that of a wind instrument. >>

# gst: immediate 'shot', the three second time window in art, music, poems and language processing

<< Is there a universal time constant for poetic lines when people read them aloud or recite them by heart? Turner and Pöppel (1988) collected over 20 types of poetry, varying from East to West and from modern societies to indigenous cultures, and found a constant of ~3 s for the duration of poetic lines. >>️

<< This observation indicates a production– perception synchrony of ~3 s, which means that we not only tend to recite poems  (and speech in a more general sense; discussed later) with a 3-s pattern but also appreciate poems aesthetically within the same temporal frame. This temporal preference for a 3-s pattern and not a 1-s or a 10-s pattern, which linguistically would be possible, indicates presumably a profound evolutionary basis. The temporal modulation effect of the 3-s window on aesthetic appreciation may also motivate to look for other concepts and phenomena of the cognitive and neural basis of aesthetic perception in general and in detail, as has been partly already done for decision processes, the visual arts, and music (Avram et al., 2013; Bao et al., 2016; Bao et al., 2017; Park et al., 2014; Park et al., 2015; Pöppel, 1989a). >>

# life: Occam's razor revisited, miss opportunities to improve through subtraction

<< A new study explains why people rarely look at a situation, object or idea that needs improving -- in all kinds of contexts -- and think to remove something as a solution. Instead, we almost always add some element, whether it helps or not. >>️

<< It happens in engineering design, which is my main interest, (..) But it also happens in writing, cooking and everything else -- just think about your own work and you will see it. The first thing that comes to our minds is, what can we add to make it better. Our paper shows we do this to our detriment, even when the only right answer is to subtract. Even with financial incentive, we still don't think to take away. >> Leidy Klotz.️

# gst: increase transport with disorder

<< Overcoming the detrimental effect of disorder at the nanoscale is very hard since disorder induces localization and an exponential suppression of transport efficiency. (AA) unveil novel and robust quantum transport regimes achievable in nanosystems by exploiting long-range hopping. (They) demonstrate that in a 1D disordered nanostructure in the presence of long-range hopping, transport efficiency, after decreasing exponentially with disorder at first, is then enhanced by disorder  [disorder-enhanced transport regime] until, counterintuitively, it reaches a disorder-independent transport regime, persisting over several orders of disorder magnitude in realistic systems. >>️

# life: cascading effects of noise on plants

<< Though noise may change moment by moment for humans, it has a more lasting effect on trees and plants. (..) human noise pollution affects the diversity of plant life in an ecosystem even after the noise has been removed. This is the first study that explores the long-term effects of noise on plant communities. >>

AA << found support for long-term negative effects of noise on tree seedling recruitment, evenness of woody plants and increasingly dissimilar vegetation communities with differences in noise levels. Furthermore, seedling recruitment and plant community composition did not recover following noise removal, possibly due in part to a lag in recovery among animals that disperse and pollinate plants. (They) results add to the limited evidence that noise has cascading ecological effects. Moreover, these effects may be long lasting and noise removal may not lead to immediate recovery. >>
