Why it matters

The idea in context

The mid-ocean ridge marks where tectonic plates pull apart and new crust is born — an Earth-spanning mountain system almost no one pictures, because it lies underwater. The biggest structures are not always the most visible.

Dünya’nın en uzun dağ sırası, denizin altında yaklaşık 65.000 kilometre uzanan okyanus ortası sırtıdır.

Okyanus ortası sırtı, tektonik plakaların ayrılıp yeni kabuğun doğduğu yeri işaretler — su altında olduğu için neredeyse kimsenin gözünde canlanmayan, Dünya'yı saran bir dağ sistemi. En büyük yapılar her zaman en görünür olanlar değildir.

WonderHistory

The Space Race turned the sky into a political battlefield — and accidentally built the world we live in.

It began in October 1957, when Sputnik — a beeping metal sphere just 58 cm wide — passed over America and triggered the creation of NASA within a year. Twelve years later, Apollo 11 stood on the Moon. But the race's real legacy is under your thumb: weather and communication satellites, GPS navigation, and a young microchip industry supercharged by Apollo's demand for tiny, reliable electronics. The rivalry was political; the infrastructure it left behind became everyone's.
