TED: Så kommer James Webb-teleskopet förklara universum för oss
The James Webb Space Telescope is a miracle of modern science and engineering. With a 21-foot, gold-coated mirror protected by a sunshield that’s the size of a tennis court, it’s the world’s most powerful telescope and humanity’s latest attempt to answer questions like: ”Where did we come from?” and ”Are we alone?”
(It also needed to be folded up like origami in order to launch into space.) Nobel Laureate John C. Mather, the leader of the team at NASA that built the Webb, explains how the telescope will observe the first galaxies to form in the early universe, peer behind clouds of cosmic dust and gas to reveal stars being born and uncover new details about places like Europa and Titan, which could harbor life. ”We’re going to get a great surprise from this telescope,” Mather says.
TED: Så får du ett mer hälsosamt och positivt förhållande till sex
From our fear of women’s bodies to our sheepishness around the word ”nipple,” our ideas about sex need an upgrade, say sex educators (and hilarious women) Tiffany Kagure Mugo and Siphumeze Khundayi. For a radical new take on sex positivity, the duo take the TED stage to suggest we look to Africa for erotic wisdom both ancient and modern, showing us how we can shake off problematic ideas about sex we’ve internalized and re-define pleasure on our own terms. (This talk contains mature content.)
TED: Datadriven journalistik avslöjar orättvisor
A blank spot on a digital map can signal much more than a gap in data — it can mean something is being intentionally hidden. Sharing the remarkable discovery of massive alleged detention camps in Xinjiang, China, Pulitzer Prize-winning journalist Alison Killing shows how governments can obscure human rights abuses by limiting journalist access on the ground — and calls for more reliable open-source data (like satellite and social media imagery) to shine a light on the world’s darkest places.
