# s-gst: literature with arithmetic inside

AA << graphed the happiness and sadness of words that occurred across the pages of more than 1,300 fiction works to reveal the emotional arcs and discovered relatively few variations >>

<< A different study (..) found that sentence lengths in books frequently form a fractal pattern—a set of objects that repeat on a small and large scale, the way small, triangular leaflets make up larger, triangular leaves that make up a larger, triangular palm frond >>

<< Why analyze the mathematics of literature? >>

# s-phys: squeezing hydrogen ... they're looking at something that's never existed before

<< This is the holy grail of high-pressure physics [..] It's the first-ever sample of metallic hydrogen on Earth, so when you're looking at it, you're looking at something that's never existed before >> Isaac F. Silvera

<< To create it [metallic hydrogen], Silvera and Dias squeezed a tiny hydrogen sample at 495 gigapascal, or more than 71.7 million pounds-per-square inch - greater than the pressure at the center of the Earth >>

<< In addition to helping scientists answer fundamental questions about the nature of matter, the material is theorized to have a wide range of applications, including as a room-temperature superconductor >>

# s-chem: a viscoelastic tongue with reversible saliva (spit and softness) to hang on to the next meal

<< A frog uses its whip-like tongue to snag its prey faster than a human can blink, hitting it with a force five times greater than gravity >>

<< A frog's saliva is thick and sticky during prey capture, then turns thin and watery as prey is removed inside the mouth >>

<< The tongue, which was found to be as soft as brain tissue and 10 times softer than a human's tongue, stretches and stores energy much like a spring >>

<< This combination of spit and softness is so effective that it provides the tongue 50 times greater work of adhesion than synthetic polymer materials such as sticky-hand toys >>

<< There are actually three phases (..) When the tongue first hits the insect, the saliva is almost like water and fills all the bug's crevices. Then, when the tongue snaps back, the saliva changes and becomes more viscous—thicker than honey, actually—gripping the insect for the ride back. The saliva turns watery again when the insect is sheared off inside the mouth >>

# s-gst: lastly, they indicate the generality of that

<< Lastly, [AA] indicate the generality of this phenomenon by demonstrating suppression of chaotic oscillations by coupling to a common hyper-chaotic system. These results then indicate the easy controllability of chaotic oscillators by an external chaotic system, thereby suggesting a potent method that may help design control strategies. >>
