The Channel Tunnel – Longest Underwater Tunnel in the World It connects 🏴England and 🇫🇷France under the English Channel. The tunnel stretches 50.5 km with 37 km underwater, making it the longest underwater section of any tunnel in the world. It takes around 35 minutes to…



The Millau Viaduct 🇫🇷 Located in France, it’s the tallest bridge in the world, with a height of 343 meters. Taller than the Eiffel Tower, it spans the Tarn River Valley and was completed with extreme precision using GPS. It can withstand strong winds, temperature changes, and…

The Atacama Desert in Chile is one of the driest places on Earth and is perfect for astronomy. Engineers built the ALMA Observatory at 5,000 meters altitude to avoid atmospheric moisture. Its location allows scientists to observe distant galaxies with incredible precision. The…

China’s Three Gorges Dam on the Yangtze River is the world’s largest hydroelectric power station in the world by installed capacity (22,500 MW). The dam is about 2.3 km long and 185 m high. It creates a reservoir nearly 600 km long, stretching upriver behind the dam. When the…

Dubai’s Palm Jumeirah is a man-made island shaped like a palm tree with a trunk, fronds, and a surrounding crescent that acts as a breakwater. GPS and satellite imagery were used extensively to get the shape perfect. Interestingly, the island wasn’t built using concrete or…

Mount Everest rises by about 1 cm per year because the Indian tectonic plate is slowly pushing under the Eurasian plate. This tectonic collision causes the Everest to rise over time. Scientists track this growth using GPS technology and satellite measurements. It’s a great…

Around 10,000 to 5,000 years ago, the Sahara Desert was a lush, green landscape with rivers, lakes, animals like hippos and giraffes, and even human settlements. This happened due to changes in Earth’s orbit, which shifted monsoon rains northward during a period called the…

Top 10 Longest Flight Journey in the World: 1. 🇺🇸 New York to 🇸🇬 Singapore: 15332 km 2. 🇺🇸 Newark to 🇸🇬 Singapore: 15329 km 3. 🇳🇿 Auckland to 🇶🇦 Doha: 14526 km 4. 🇬🇧 London to 🇦🇺 Perth: 14499 km 5. 🇺🇸 Dallas to 🇦🇺 Melbourne: 14468 km 6. 🇫🇷 Paris to 🇦🇺 Perth: 14265 km 7. 🇳🇿…

Plants can communicate by releasing chemical signals into the air or soil. For example, when a plant is attacked by pests, it may release volatile organic compounds (VOCs) that nearby plants detect, triggering them to produce defensive compounds to protect themselves.

Piezoelectric generation is a method of converting mechanical energy (like pressure, vibrations) into electrical energy using special materials called piezoelectric materials. Common Piezoelectric Materials: 1. Quartz 2. Lead zirconate titanate (PZT) 3. Rochelle salt

Engineers use which type of map to analyze land elevation and slope?
If it’s 12:00 noon in Greenwich (0° longitude), what time is it at 90°E?
Using tissue engineering, scientists can grow real meat from animal cells in a lab. No slaughter involved. It’s a more sustainable and ethical way to produce meat. Can it be an alternative to farm animal?

DNA can store petabytes of data in a single gram which is far more than any hard drive. 🚨Just 1 gram of DNA can store 215 petabytes (215 million GB) of data. Bioengineers are developing molecular storage systems based on DNA’s four-letter code for massive data archiving.…


Do you know?🚨 Pythagorean tuning is a system of musical tuning where all the intervals are based on the perfect fifth, which has a frequency ratio of 3:2. If we start with some frequency and go up and down by powers of 3/2, we create the 'circle of fifths'.

A transformer is a device that changes the voltage of electricity. It can either increase it (step up) or decrease it (step down) keeping the frequency (50Hz or 60Hz) constant. 💡This is super useful because different devices need different voltages to work properly. 🚨Think of…
