- The Gulf of Aqaba (Arabic: خَلِيج الْعَقَبَة, romanized: Khalīj al-ʿAqaba) or Gulf of Eilat (Hebrew: מפרץ אילת, romanized: Mifrátz Eilát) is a large gulf at the northern tip of the Red Sea, east of the Sinai Peninsula and west of the Arabian Peninsula. Its coastline is divided among four countries: Egypt, Israel, Jordan, and Saudi Arabia. The northernmost coral reef in the world is situated near the Eilat shore.
- Real number (Wikipedia)
In mathematics, a real number is a number that can be used to measure a continuous one-dimensional quantity such as a distance, duration or temperature. Here, continuous means that pairs of values can have arbitrarily small differences. Every real number can be almost uniquely represented by an infinite decimal expansion.
