National Grand Theater of China which is sometimes referred to as Beijing Opera House, but is nicknamed “The Egg” is actually officially called – National Centre for Performing Arts (国家大剧院). It is one of the new landmarks of the city which is located in the very heart of it, right next to Great Hall of the People in Tian An Men Square. What makes it apart is the unusual architecture that looks like an egg. The building is surrounded by an artificial lake and when looking at it and it’s reflection it forms the shape of an egg. It is especially beautiful in the evening when it’s titanium and glass dome is sparkling lights.
First time I saw this ellipsoidal construction being built in the heart of Beijing, I assumed they are building a sports arena, a stadium of some kind. But of course I was wrong, it was the Opera House as I’ve been told. In December 2007, after 6 years since the beginning of construction, the first concert was held and “The Egg” became part the Chinese capital city.
The coordinates of an antipode are in fact easily calculated by the following formula: If the coordinates (longitude and latitude) of a point on the Earth’s surface are (θ, φ), then the coordinates of the antipodal point can be written as (θ ± 180°,−φ). But there’s no actual need for you to calculate this, there are plenty of interactive maps online that will show you the exact antipode providing the initial point on earth. I know you must be anxious to find out who lives on the other side, so go ahead then, try these links:
