Pay for Extra Luggag in Rail Journey: 'প্রেসক্রাইবড ফ্রি অ্যালোয়েন্স লিমিট' পেরিয়ে গেলেই যাত্রীদের বইতে হবে অতিরিক্ত টাকা। অচিরেই হয়তো লাগু হতে চলেছে অতিরিক্ত মালের জন্য অতিরিক্ত টাকা। এ বিষয়ে ঠিক কী জানালেন রেলমন্ত্রী?

The Secret of the Crocodile “Death Roll”

Science is full of arcane terminology. Why use an easy-to-understand or evocative word when an opaque and overwrought phrase will do? But there are exceptions. Like “death roll.” If you grew up watching David Attenborough specials, you’ve probably heard the term over slow-motion footage of crocodiles tearing wildebeest apart. It means exactly what you think. The behavior is the powerful and violent twisting that wrenches limbs from sockets and muscle from bone when a crocodylian clamps onto a morsel and does its best impression of a washer on spin cycle. The process is so fascinating that the flashes of white teeth and red innards are deemed suitable for broadcast, even if momentarily. Do all crocs do this? American alligators, saltwater crocodiles, and Nile crocodiles have gotten a fair amount of press for the skill, but there are over 20 other living species. Not to mention the burgeoning ranks of fossilized snappers, including monsters like the 40 foot-long alligator relative Deinos...

  What stops us from getting to Mars any faster? Well it’s mainly the technology. Our technology isn’t advanced enough to get to Mars faster. The fastest time for getting to Mars, is about 39 days. This was the space craft that was designed to go to Pluto and explore it. It left the Earth at a whopping 36,000 mph. Of course, there is also this problem. The distance between two planets isn’t a straight line. Traveling through the farthest passing of Earth and Mars would involve a trip directly through the sun, while spacecraft must of necessity move in orbit around the solar system's star. Although this isn't a problem for the closest approach, when the planets are on the same side of the sun, there is yet another problem. The numbers also assume that the two planets remain at a constant distance; that is, when a probe is launched from Earth while the two planets are at the closest approach, Mars would remain the same distance away over the course of the 39 days it took the prob...
