The East African Rift, also called the Great African Rift Valley, is an active continental rift zone where the Nubian and Somalian plates pull apart.
East Asian age reckoning
East Asian age reckoning, also known as Korean age reckoning, counts a person as 1 year old at birth, adding a year at each New Year.
East Asian monsoon
The East Asian monsoon is the seasonally reversing wind system over eastern China, Korea, Japan, and the adjacent western North Pacific, bringing wet summers and cold, dry winters.
East Asian rainy season
The East Asian rainy season, called Meiyu in China, Baiu in Japan, and Changma in Korea, is a quasi-stationary frontal system bringing heavy rain in June and July.
East Asian winter monsoon
The East Asian winter monsoon (EAWM) drives cold, dry air from the Siberian high toward the western Pacific, bringing cold surges, snowfall, and freezing rain to East Asia.
East Atlantic pattern
The East Atlantic pattern is a North Atlantic atmospheric teleconnection, the second leading mode of low-frequency variability in all months, and a key indicator of weather regimes affecting Europe.
East Atlantic/West Russia pattern
The East Atlantic/West Russia (EAWR) pattern is a prominent Northern Hemisphere teleconnection pattern, identified in 1987, that links weather over the North Atlantic and Europe to conditions across Russia and Asia.
East Australian Current
The East Australian Current is a major ocean current flowing south along Australia's east coast from the Coral Sea, known for large eddies and warming the Tasman Sea.
East Greenland Ice-core Project
The East Greenland Ice-core Project, known as EastGRIP, drilled a 2,670-meter ice core through the Northeast Greenland Ice Stream, the first deep core through a fast-flowing ice stream.

Eastern Time Zone
The Eastern Time Zone, one of nine official US time zones, covers the Atlantic coast states and eastern Canada; its standard time is 5 hours behind UTC.
Eastin–Knill theorem
The Eastin–Knill theorem is a no-go result in quantum error correction, proven by Bryan Eastin and Emanuel Knill at NIST and published in 2009, forbidding a universal transversal encoded gate set.
Easton's theorem
Easton's theorem is a result in set theory, proved by William Easton, stating that the continuum function at regular cardinals is constrained only by monotonicity and König's theorem.
