Flatland is a great way to introduce kids to the concept of dimensions , a technical concept in physics and mathematics that defies our everyday notion of physical space. Indeed, the novel is arguably one of the best introductions to this heady subject short of having Sean Carroll , a physicist at the California Institute of Technology, explain dimensions to you himself.“The idea of dimension in pop culture is sometimes misunderstood like there’s a place you can go, a mystical dimension or something like that,” Carroll says. “To a physicist or mathematician, a dimension is just a direction.”
They found that 89 percent of Amazon Fire TV channels and 69 percent of Roku channels contained easily spottable trackers that collected information about a viewing habits and preferences, along with unique identifiers like device serial numbers and IDs, Wi-Fi network names, and the Wi-Fi identifiers known as MAC addresses.
Sean Carroll Thinks We All Exist on Multiple WorldsIn his book Something Deeply Hidden, the physicist explores the idea of Many Worlds, which holds that the universe continually splits into new branches.Most of us think in terms of three dimensions in our day-to-day lives. But physicists deal with several additional dimensions—10 or more if you’re a string theorist . Where are these dimensions hidden? It’s a question just as likely to perplex a child as a grown adult, so Carroll took WIRED up on the challenge of answering it at five levels of complexity.
Carroll starts by introducing the concept of multiple dimensions to a nine-year-old with Tinkertoys and builds upon these simple concepts until you’re convinced you might be able to build an interdimensional wormhole if you really wanted to. At the very least, by the end of WIRED’s latest “Five Levels ” video, you’re guaranteed to know your De Sitter space from your p-branes, so you never embarrass yourself at a party again.Check it out. You can also watch the next two episodes (about Lasers and Sleep) now, on WIRED’s free app for Roku, Apple TV, Android TV, and Amazon Fire TV.
Jason Parham writes about pop culture for WIRED.Across its mostly terrific eight-episode first season, which concluded Sunday, Levinson introduced explicitly hard-to-swallow themes—drug addiction, domestic abuse, the hazards of online hookups, pedophilia, depression—and didn't hold back with regard to the physical and psychological violence these issues havoced on his characters.
