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 difficult 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 the computations done 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 actually programmed: the slow one. And the fast one? Well, it was the cosmic rays, the accidental genetic mutations and dying animals that built the fast one - and wrote and installed the same program that it took a team of human programmers 4 years to write. Some people really believe that.
Some, in the privacy of their study, are willing to suspend their disbelief just long enough to grasp a moment of true objectivity. Some are willing, for a moment, to put their theological prejudices aside and presume absolutely nothing about God - and look at just the observed fact and ask themselves the question that is never asked: Is it more likely that a computer that can perform 124 trillion timed, organized and purposeful computations in 1/25 of a second was desiged or is it more likely that "happened" by a series of hypothetical extremely fortunate random genetic mutations and dying animals?
Not only does this brain calculate at incomprehensible speeds, but it holds an inconceivably large amount of data.
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.
See National Geographic, February, 2014, page 44, where the neurons of a mouse brain are compared to a human brain.
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 genetic mutations and dying animals!
Is there no level of complexity that will cause logical minds to reconsider?
Science once taught that the world is flat and balanced on the back of a giant turtle. But, if science had, in that day, done the unthinkable and looked a scripture it would have found that the world is in fact circular and hung upon nothing (Job 26:7,10).
