Formula 1 cars use carbon-carbon composite brakes because they can withstand extreme temperatures (over 1000°C) and provide superior stopping power compared to traditional materials. Carbon fibre brakes offer exceptional heat resistance and thermal stability, which is crucial when braking from speeds over 350 km/h. Iron and steel would be too heavy and could not handle the thermal stress, while platinum is prohibitively expensive and not suitable for this application.

F1 drivers experience deceleration forces of 5-6 G when braking from high speeds, which is comparable to the impact of driving a regular car into a brick wall at 300 km/h. Carbon-carbon brakes allow F1 cars to decelerate from over 350 km/h to under 100 km/h in just 4 seconds. This extreme braking force subjects drivers to massive physical stress, requiring exceptional neck and core strength.

Formula 1 refuelers (when refueling was allowed until 2009) could supply approximately 12 liters of fuel per second. This high flow rate was necessary to complete pit stops quickly, with typical refueling taking around 6-8 seconds. The values 6, 7, and 18 liters per second are not accurate for F1 refueling systems.

When IBM was asked to leave India in 1977 due to FERA regulations, Wipro entered the IT sector by licensing technology from Sentinel Computers (USA). Wipro developed India's first mini-computer and the first Indian 8086 chip. HCL and CMC were also early IT companies but did not achieve these specific milestones.

Thomas M. Nies founded CINCOM (originally Cincom Systems) in 1968 and became the longest-serving actively serving CEO in the computer industry. Computer Associates was founded by Charles Wang and Russell Artzt, BMC by John Bailly, and Unisys was formed from a merger of Burroughs and Sperry.

Bill Gates wrote 'The Road Ahead' in 1995, founded the digital imaging company Corbis in 1989, and joined Berkshire Hathaway's board in 2004. These are all well-documented facts about Gates' career beyond Microsoft. Warren Buffet is the CEO of Berkshire Hathaway, not the director described.

Surface tension is the correct phenomenon that allows mosquitoes to float on water. The small mass of mosquitoes distributes their weight over the water's surface without breaking the surface tension film. Buoyancy applies to objects submerged or partially submerged in fluid, while capillarity involves liquid movement in narrow spaces.

Water is unique because its solid state (ice) is less dense than its liquid state. As water cools below 4 degrees Celsius, it begins to expand, reaching maximum expansion at the freezing point. Most other liquids, like mercury or oil, contract when freezing.

Koala bears are one of the few non-primate mammals that have fingerprints. Their fingerprints are so similar to human fingerprints that they can be confused with them even under electron microscopy. Cats, squirrels, and parrots do not have fingerprints in the same anatomical sense.
