A COMPUTER CALLED "K"

One of the 5 most powerful computers in the world is called "K." Its name derives from the Japanese word "kei" meaning 10 quadrillion, the approximate number of computations that K performs in one second. K runs 82,944 processors simultaneously and consumes the same amount of energy as 10,000 suburban homes. K is massive. It is no less that twelve 40 foot aisles of tall metal cases full of computer equipment.

An international team of programmers programmed K for approximately 4 years for the purpose of simulating the human brain. Their program mirrored the connections between 1.73 billion virtual nerve cells connected to 10.4 trillion virtual synapses. Each virtual synapse was positioned between excitatory neurons and each contained 24 bytes of memory. The entire project used one petabyte of main memory, which is roughly equal to 250,000 home computers linked together. (See io9.com).

K and the computer program were successful in simulating 1% of the human brain's calculations over a time period of 1 second. It took K 40 minutes to complete the task. No computer in the world could do the job much faster - except, of course, a real brain. When the numbers are computed, the brain computes 100 times as much as K and 2400 times the speed ( 1 second vs 40 minutes ); the brain is therefore 240,000 times as powerful as K.

Consider this. The click of the shutter on an inexpensive camera takes approximately 1/25 of a second. It is so fast that it is practically impossible to hear that it is really two clicks, one to open the shutter and the other to close it. Yet, in that faction of a second K has completed 52,000,000,000 computations. In the same period of time, your brain has completed 2400 times that number, or 124 trillion. It took a team of programmers 4 years to complete the programming of one second of computations in 1/100 of a human brain.

There are, of course, two computers in this comparison. One is K and the other is the brain. K, the slow one, requires enough electricity to run 10,000 homes. The fast one does the same thing on a crust of bread. The slow one requires 40 minutes to complete one particular job; the fast one takes 1 second. The slow one is the size of a large house; the fast one is 87 cubic inches.

Interesting, is it not, that some people argue that only one of these computers was programmed: the slow one. And the fast one? Well, it was the cosmic rays, the accidental mutations, the environmental pressures and dying animals that built the fast one. And some people really believe that. But some are willing to put their theological prejudices aside and presume absolutely nothing about God, and look at just the facts and ask themselves the question that is never asked: Is it likely that a computer that can perform 124 trillion timed, organized and purposeful computations in 1/25 of a second actually desiged? Or did it just "happen" as a result of accidental mutations and environmental pressures?

Not only does this brain calculate at incomprehensible speeds, but it holds an inconceivably large amount of data. See National Geographic, February, 2014, page 44, where the neurons of a mouse brain are compared to a human brain:

"A human brain visualized at this level of detail would require an amount of data equal to all the written material in all of the libraries of the world."

So here we have a living computer that holds an amount of data equal to all of the material in all of the libraries in all of the world and which utilizes this data to compute at a rate of 124 trillion computations in 1/25 of a second. And this is supposed to have been produced through a series of unseen but very fortunate accidental mutations and dying animals !

One might as well return to the closed minds that once taught that the world is flat and balanced on the back of a giant turtle. But, of course, if "enlightened science" had paid more heed to scripture when scientists believed the world is balanced upon a turtle, they would have learned instead that it is circular (Job 26:10) and "hung upon nothing" (Job 26:7) by its Creator.
