What is the speed of thought?

Is it true that thought has the greatest speed imaginable? Once, in ancient times, this was considered indisputable, which explains such expressions as "faster than thought." Today we know that a thought is an impulse that travels along the nerve fibers of our body and that the speed of this impulse can be measured quite accurately. An amazing thing turns out: it turns out that thought is a very slow process.

The nerve impulse travels at a speed that is only 155 miles per hour (about 250 km/h)! This means that any information can be transferred faster outside our body than inside it, from one organ to another! Television, radio, telephone - all these media transmit information much faster than our nervous system.

A thought transmitted along the nerves from New York to Chicago will arrive at its destination a few hours later than the same thought transmitted by radio, telephone or telegraph. When something happens to our toe, it takes some time for an impulse with information about it to reach the brain.

Imagine that you are a giant whose head is in Alaska and whose feet are in South Africa. If you get bitten by a shark on your toe on a Monday morning, your brain won't know anything about it until Wednesday night. And if you decide to pull your finger out of the water, then the rest of the week will be spent sending the command to your feet!

Different kinds of signals cause us to react at different speeds. We respond faster to sound than light, bright light faster than dim, red faster than white, and something unpleasant faster than something pleasant.

The speed of passage of mental impulses for each person is slightly different. Therefore, some people react much faster than others to some signals.

Random interesting fact from the Great Encyclopedia:

Why was the chiming of the chimes on television delayed for a minute during the meeting of the New Year 1992?

At the end of 1991, there was complete confusion with the New Year's address to the people. Gorbachev had already resigned as president of the USSR, and RSFSR President Yeltsin did not write down the appeal. The honorary role was offered to Mikhail Zadornov, who was the host of the Blue Light. The satirist spoke live and was so carried away that he spoke for a minute longer. For his sake, the chimes were delayed.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

AMD Radeon R7 260 graphics accelerator 22.12.2013

AMD has announced the Radeon R7 260 graphics card, which will take an intermediate position between the $140 Radeon R7 260X and the $90 Radeon R7 250. Thus, the cost of new items should not exceed $110.

The presented video adapter belongs to the Bonaire family. It has 768 stream processors and 48 texture units. The core frequency of the chip is 1000 MHz, the frequency of 5 GB GDDR1 memory with a 128-bit bus is 6000 MHz.

For the Radeon R7 260, a 28-nanometer manufacturing technology is provided. Claimed performance reaches 1,54 Tflops (trillion floating point operations per second). DirectX 11.2 and OpenGL 4.3 APIs are supported. The maximum value of dissipated thermal energy is 95 W.

The novelty implements TrueAudio hardware sound processing technology. It takes care of complex audio calculations and subsequent mixing, regardless of the load on the processor or video accelerator. The TrueAudio chip is equipped with a variety of digital signal processors optimized for audio processing, supports the Tensilica HiFi2-EP instruction set and Tensilica Xtensa SP floating point calculations. Each core is equipped with 32 KB of instruction cache and 32 KB of data cache, as well as 8 KB of fast memory to speed up local operations. In addition, there is 384KB of shared cache on the chip, and the processor itself can address up to 64MB of GDDR5 memory.

The Radeon R7 260 graphics card will go on sale in mid-January 2014.
