IBM Summit It's shiny, fast and ultra powerful. But it's not the latest Alfa Romeo. A physics laboratory in Tennessee just unveiled Summit, likely to be named the world's speediest and smartest supercomputer. "IBM Summit - The latest phenomenon in the computing world This supercomputer is extremely fast. Precisely, "If  every person on the earth  completed one calculation per second, it would take the world population 305 days to do what Summit can do in 1 second,"  according to an ORNL statement. Put another way, if one person were to run the calculations, hypothetically, it would take 2.3 trillion days, or 6.35 billion years what this machine can do in just 1second!!   The supercomputer — which fills a server room the size of two tennis courts — can spit out answers to 200 quadrillion (or 200 with 15 zeros) calculations per second, or 200 petaflops, according to Oak Ridge National Laboratory, where the supercomputer resides....

A wormhole is a theoretical passage through space-time that could create shortcuts for long journeys across the universe. Wormholes are predicted by the theory of general relativity. But be wary: wormholes bring with them the dangers of sudden collapse, high radiation and dangerous contact with exotic matter. Wormholes were first theorized in 1916, though that wasn't what they were called at the time. While reviewing another physicist's solution to the equations in Albert Einstein's theory of general relativity, Austrian physicist Ludwig Flamm realized another solution was possible. He described a "white hole," a theoretical time reversal of a black hole. Entrances to both black and white holes could be connected by a space-time conduit. A wormhole can be visualized as to take a sheet of paper and draw two somewhat distant points on one side of the paper. The sheet of paper represents a plane in the  ‘ spacetime continuum’ and the two points re...

Nessie or the Loch Ness monster, is the name given to a gigantic creature known to have been seen in the lake of Scotland. Though there are dozens, if not hundreds, of lake monsters around the world, one superstar marine denizen outshines them all: Nessie, the beast said to inhabit Scotland's Loch Ness. The first purported photo of Nessie was published in The Daily Mail on April 21, 1934. Some say it's a myth; others say it's a living dinosaur or even a sea serpent that swam into the lake before it became landlocked. Although sightings of a strange creature in Loch Ness have been traced back to the sixth century, the modern legend began in 1933 when a journalist and water bailiff (a sort of lake policeman) reported seeing a dragon-like monster in the famed body of water. Like other reputed lake monsters around the world, those who are convinced that Nessie exists have tried to pass legal measures to protect them. There is of course a strong incenti...

Sometimes, we talk about what the biggest number is and then arrive at the answer: INFINITY. But, infinity is not a number in a real sense. So, the largest number closest to infinity is ‘Graham’s number’. This number is so huge that it is said that even the entire universe will not be enough to write on! Graham’s number is really big, but of course, it's precisely 0% as big as infinity. On the other hand, everything we touch is finite, so in some sense, Graham's number is probably "close enough" to infinity for doing most math.  Sometimes when we talk about big numbers, we talk about how many digits they have or, basically equivalently, write them in scientific notation involving some power of 10. A googol, for example, is 10^100, which has 101 digits. The largest known prime number has over  17 million digits. But, Graham’s number is ridiculously larger than googol or googolplex. It is so huge that it cannot even be mentioned in scientific notation of ra...

Crocodile Paradox Moore's Paradox Ship of Theseus The  crocodile paradox , also known as crocodile sophism, is a paradox in logic. It is stated as, a crocodile that has stolen a child, promises his parents that their child will be returned if and only if, they correctly predict what the crocodile will do next. The statement and the course of action is logically smooth and simple if the parents guess that the child will be returned, but a dilemma arises for the crocodile if the parents guess that the child will not be returned. Let’s try to understand this by the following two cases: Suppose that the parents guess that their child will not be returned. Case1: Now, if the crocodile decides not to return the child and keep him with it then,  he violates his terms: the parent's prediction has been validated, and the child should be returned. Case 2:   But, in the case that the crocodile decides to give back the child, he still violates his ter...
