[EX Q]: 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.)

[EX Q]: PHILADELPHIA --  Haason Reddick  is coming home to go after Carson Wentz.
The rookie linebacker returns to the field where  he  starred in college when the Arizona Cardinals (2-2) visit the Philadelphia Eagles (3-1) on Sunday.
"When my name was called  the response was crazy  " Reddick  said.
 Reddick  expects a large number of family and friends cheering for him at the Linc. How will the rest of the Eagles fans react?
"I think the crowd will be welcoming  but we'll see what happens "  Reddick  said. "You never really know with the Philly crowd. The Philly crowd has always been a wild crowd. Philly will always be home. I'll always have love for Philly."
 Reddick  has 10 tackles in four games but is still seeking  his  first sack.  He 'll get a chance to rush the quarterback more this week because  he 's moving from inside linebacker to the outside spot to replace the injured Markus Golden .
"Whatever the team needs  I'm willing to do  whether it's taking snaps at outside or getting reps at inside  " Reddick  said. "Pass rusher is more natural. I'm getting back into the groove and being focused on pass rushing  making sure I'm being a smart pass rusher."
