The Tower of Pisa started leaning even before it had been completed, and it soon became one of the world’s most famous landmarks. However, after several years of restoration work, engineers have now managed to straighten it by 4 cm, after its wonk got so severe that it had to be closed to the public. If it was straightened completely, would it lose its appeal? Sometimes imperfect is better than flawless! Close shave: You know you’re having a bad day when you’re ordered to start shaving train platforms. That’s right, shaving platforms. In 2014 it turned out that a simple miscalculation by a French rail company meant that almost 2,000 new trains were going to be too wide for 1,300 of the country’s train platforms. An embarrassing faux pas, non? The not-so-tough warship: The tough-guy Vasa warship had everything: guns, guns and… more guns. It was so big, so strong, so absolutely undefeatable that it promptly sank, killing 30 sailors minutes after leaving its Swedish home. This embarrassing tragedy, which took place in 1628, was caused by at least two human errors. Firstly, the boat builders had been working from two completely different measurements. One lot measured wood in Amsterdam feet, which is about 11 of today’s inches, while the other side measured using Swedish feet. A Swedish foot was a whole inch longer. Secondly, the captain, who wanted to show off his ship’s fabulous armoury, left the gun holes wide open. So when the boat tipped, gallons of water poured in. To make the trains fit, workers were ordered to start shaving back the edges of platforms. The extra work was thought to have cost another £40 million, on top of an already pretty hefty train bill. Zut alors! Seven people lost their lives the day that the space shuttle Challenger exploded, just 73 seconds after it blasted off on a mission as part of the Space Shuttle Program. The cause? A part that couldn’t handle the unusually cold January weather. The Challenger shuttle was not the new kid on the block, this was to be its tenth flight, but that day its O-ring – a circular gasket that sealed the right rocket booster – failed, and the shuttle broke up as it flew over the Atlantic Ocean. As well as for the crew and their families, the disaster was also devastating for NASA’s space missions. Shuttle flights were put on hold for almost three years while engineers and scientists made sure that such a simple calculation could not possibly be missed again. Even we make mistakes… On page 7 of the November issue (Science of Light) we said that it takes just over 8 seconds for the light from the Sun to reach Earth. Ha! Eight seconds! That would make the temperature on Earth anything between 600° and several million degrees C, not quite the right conditions for life as we know it! Sunlight actually takes, on average, 8 minutes and 20 seconds to reach our planet. I’m not sure what got into us, perhaps it was all that talk of megaparsecs. Whatever it was, we are really very sorry and hope that this helps to right our wrong! Well done to all our eagle-eyed AQUILAnauts who spotted this error! Jasmine The explosion of Challenger:
