IBM's new supercomputer (fastest in the world)

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.

The former "world's fastest supercomputer," called Sunway TaihuLight, can perform 93 quadrillion calculations a second (93 petaflops), while humming away inside China's National Supercomputing Center in Wuxi.
It is an IBM AC922 system that's made up of 4,608 computer servers — each comprising processors (the brains of the computer). But what's actually going on inside these processors is what makes the difference.

"Summit's computer architecture is quite different from what we have had before," Daniel Jacobson, a computational biologist at ORNL, who is working on Summit, told Live Science. For one thing, the computer uses the new Tensor Core feature in its graphics cards (made by Nvidia), which is designed specifically for applications focusing on machine learning and artificial intelligence (AI), and to be fast.

The Loch Ness Monster

Image
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

3Logical Paradoxes!

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 terms, ev
