A planetarium is a large dome shaped theater in which the crowed looks to the top of the dome which is projected with video shows about astronomy and the night sky. Some planetariums have movement features that help simulate the movement and complexity of different objects in the galaxy. Some planetariums also use lasers and other advanced means...
Jerry: Dad, it’s got lots of other functions. Morty: Don’t worry. I’ll get to the other functions.. (Seinfeld, The Wizard) Technology is moving faster and faster, and consumers are having a hard time keeping up. The phone you bought just last year knowing it’s the best in the market, looks today like old news with poor...
Engineering pushes limits, and now and then those limits push back. From bridges that twisted apart in the wind to dams that gave way, history is full of structures that failed in spectacular and tragic ways. Each one taught hard lessons that made what came after safer. Here are ten of the most famous engineering disasters. After writing the 10...
Every era leaves behind structures that push the limits of what people thought possible. From ancient aqueducts to modern megaprojects, these are the feats that engineers still study and travellers still marvel at. Here are ten of the most amazing engineering achievements ever built. Mankind has achieved remarkable engineering accomplishments that...
The Romans moved water across entire regions using nothing but gravity and remarkable engineering. Many of their aqueducts still stand two thousand years later, striding across valleys on rows of stone arches. Here are ten of the most beautiful Roman aqueducts that survive today. An aqueduct is a man-made watercourse that was built to convey water...
We already composed many lists dedicated to bridges: the tallest bridges (and highest), longest bridges, scariest, movable bridges or most famous bridges. It’s about time to dedicate a post solely to stone bridges. These bridges are all centuries old and stood the test of time. We chose the 10 we think are most beautiful and impressive, but...
1. Mauna Kea Observatory (MKO), Hawaii, United States Located on Hawaii’s Big Island, on the summit of Mauna Kea mountain, the MKO is the world’s largest array of optical, infrared, and submillimeter astronomical equipment. The Mauna Kea Observatory houses more telescopes than any other single mountain peak observatory in the world 2...
Across the world, great arches have been raised to mark a victory, honour the fallen or simply welcome people into a city. Some are ancient, some modern, but each has become a landmark in its own right. Here are ten of the most famous man-made arches in the world. 1. Arc de Triomphe, Paris, France One of the most famous monuments in Paris, the Arc...
Long before satellite navigation, lighthouses were the difference between a safe arrival and disaster at sea. Many still stand on the world’s most dramatic coastlines, and a few have become landmarks in their own right. Here are ten of the most famous lighthouses anywhere. 1. Les Eclaireurs Lighthouse, Argentina Often called the lighthouse...
Some bridges do not just cross a gap, they hang dizzyingly high above it. The highest bridges in the world carry roads and railways hundreds of metres above rivers and gorges, feats of engineering that double as tourist attractions. Almost all of them are clustered in the mountains of southwest China, where deep canyons and a vast expressway...
