About the false positions in VC or how many operations per second does the brain of a person
this article has led me to post one of the most popular pages in Vkontakte, which literally was this: "the Human brain is able to perform 1016 operations per second. This means that his power is still higher than the power of any of the current computer.". I figured out who is steeper, the brain, or a computer.
First look into what kind of operations per second, what is the power of your desktop computer, and what is the power of supermegaawesome computer on the planet.
To measure the computing power of computers employs a unit of measurement known as flops (flops, flop/s). Flops shows how many floating-point operations a computer performs in one second. In addition, to measure the computing power used such a thing as a clock frequency. Processor frequency shows the number of basic operations the CPU performs per second, and is measured in Hertz. The basic operation performed by the processor may include a plurality of floating-point operations, so the measurement results in the Flopsy and Hertz are different. If you find yourself on the desktop icon "My computer", click on it right button mouse in the drop-down menu open the properties, then the truth will open for you. Look in the window title "System", and there, next to the word "processor" will indicate the clock frequency of your processor. Most likely it will look like this: "2.10 GHz". The number may vary slightly. Now, 1 GHz is 1000000000 Hertz or one billion operations per second. From this it follows that when a clock frequency of 2.10 GHz % performs 2100000000 operations per second. It certainly is bigger than 1016. When measuring the Flopsy number will increase several times.
Go ahead. The Titan supercomputer company Cray inc. has the approximate computing power of 20 petaflops. 1 petaflops is equal to 10^15 flops. Can themselves calculate what number and how many zeros. As the poet said: "well This is weird..."
Now about the brain. It's not as easy as with computers. At the present stage of development neurobiology is quite difficult to calculate the computational power of the brain and compare it with the computer. However, it should be clear that we cannot perform the same operations that performs our laptop with the same speed and in the same amounts. It is obvious that comp is more powerful, Yes? And here and there.
Let's see more how it works.
The brain is a biological neural network. A neural network consists of neurons (in the case of the brain is brain cells), each of which is associated with other neurons. The place of connection of neurons is called a synapse. Across the synapse from one neuron is transmitted by a chemical or electrical impulse to another neuron. The number of neurons in the human brain is approximately equal to 100000000000 (one hundred billion). Data from different sources vary slightly, but the overall picture is similar. Each of those neurons has between 7,000 and 10,000 synapses. On average, one synapse is 10 pulses per second, i.e., we have a clock frequency of 10 Hertz for one synaptic connection. Now entertaining mathematics: 100000000000 neurons, we multiply by 10,000, their synaptic connections and multiply all this by 10 Hz. We get a number with sixteen zeros after one, otherwise 10^16. So where did the mysterious number 1016. Apparently it just transformed during the endless census of of public public. And it turns out that our brain has more computing power than the supercomputer Titan. In the end, the author of the post about 1016 operations per second was right.
