Example Input: Two recent books look at the very human (sometimes all-too-human) process of trying to make sense of the known universe:  The Un-Discovered Islands: An Archipelago of Myths and Mysteries  Phantoms and Fakes  by Malachy Tallack  and The Planet Factory: Exoplanets and the Search for a Second Earth  by Elizabeth Tasker .  They 're so stylistically and scientifically disparate as to seem unrelated  but reading  them  in close succession makes for something greater than the sum of its parts â a joint atlas of human guesses in a world that seems destined to confound us.
 Elizabeth Tasker  knows all about that; The Planet Factory is all about the formation of worlds humanity might never clap eyes on. And if you're hoping for definitive answers about how things work closer to home  think again;  Tasker 's very clear that the scientific method is as often about being proven wrong. "The problem (and there is always a problem)" isn't just an aside on a particular theory  but a thesis for the field. This is a book about trying to map unknown seas in real time; the ghosts of the sailors peering into the dawn looking for Thule live in every telescopic survey.
The Planet Factory can feel intimidating; certainly you must come to it wanting to know everything there is to know about making planets  and hang in there as long as you can before the variables overwhelm you. ( Tasker  offers easy analogies by the handful  and while at first they may seem too easy  you'll appreciate them by the time you're trying to understand the optimum timing of planetary migration.)

Example Input: The primes are "suspicious  solitary numbers " Giordano writes. Perhaps they would prefer to be ordinary numbers  "but for some reason they couldn't do it." And he elaborates: There are some that almost touch -- 17 and 19  41 and 43 -- but are separated by an even number. As the numbers expand  these so-called twin primes become ever rarer  and the presentiment develops that these were accidents  and "that solitude is the true destiny." But then  if you count long enough  you'll find another pair of twins  "clutching each other tightly." Giordano depicts with aching vividness the traumas out of which Alice and Mattia emerge disabled. Alice's ski fall might be only that  despite a permanently crippled leg. But we get horror seen from within: a father who bullies her  even if lovingly  into enduring the cold  the awkwardness  the fear of something she has so little taste for that she humiliatingly befouls her ski pants. Adults cannot suspect what furnishes a child's nightmare; here  the reader is made to live it.
 Giordano remarkably and movingly portrays the hesitant groping toward warmth that works beneath the pair's emotional disabilities. Alice  unable to tolerate not just food but also the vitality it stands for  assumes a touchingly decisive if frail seductiveness with the shaky Mattia. When at 22 he brings himself to tell her about his sister  she embraces him  they kiss  and for a moment it seems things will change.
 Only briefly; Mattia retreats  goes off to Scandinavia. Upon his return years later there is another almost-moment. That too will vanish. Alice's reaching out  though tentative  is genuine. His response describes a parabola: rising  seeming to converge  dropping away. He is the man who fell to earth; she is earth  though crumbly.
 What is even more distinctive  and transforming  is the writing. The author works with piercing subtlety. He manages -- moving from math to physics -- an exquisite rendering of what one might call feelings at the subatomic level  emotion's muons  gluons and quarks. Take that kiss: "All Mattia saw was a shadow moving toward him. He instinctively closed his eyes and then felt Alice's hot mouth on his  her tears on his cheek  or maybe they weren't hers  and finally her hands  so light  holding his head still and catching all his thoughts and imprisoning them there  in the space that no longer existed between them."

Example Input: Cait Earnest  28   met Chris Brandt on a dating app in 2015  and was asked to join his already existing relationship with husband Matthew.
âI had never been with two people at the same time before. Itâs different strokes for different folks but I would say itâs a pretty fun sex life â  Earnest  said.
âIn regards bed placing  it does complicate things. Matthew and I used to sleep on opposite sides and then  Cait  came long â Chris said. âIf I wanted to stay on the same side   Cait  would have to be in the middle and we found quickly  she  didnât like that.â
Both  Cait  and Matthew experienced bouts of jealousy at the start of their relationship experiment but said thatâs now all in the past.
âIt was a struggle even for me. The insecure part of me was like  âChris loves me more because heâs been with me longer â but then he told me  âI love you just as much as I love  Cait  â so I was like  âI need to come to terms with that ââ Matthew said.
 Cait  said  she  isnât shy about sharing  her  relationship status.
âWhen we meet somebody at a bar  I will usually say  âHi  Iâm Cait and these are my two boyfriends.â People often ask if Iâm joking â  she  said  adding that even  her  grandpa is on board and asking when  she âs planning on getting pregnant.
