When do we stop growing?

The body length of a newborn is on average about fifty centimeters. In twenty years, this tiny body more than triples in size. The average height of a man is 1,7 meters. But even then the person does not stop growing. It continues to grow even at twenty-five years of age and reaches its maximum growth at about thirty-five to forty years of age. What happens then? It not only stops growing, but begins to "shrink".

On average, a person "dries out" by ten millimeters every ten years after forty. The reason for this "shrinkage" is the drying of cartilage in the joints and in the spine. The growth rate depends on the season. Children grow faster in summer than in winter. For example, school-age children grow twice as fast during the summer months as they do during the winter! Improved nutrition, improved lifestyle - these and some other circumstances make each subsequent generation higher than the previous one on average.

Growth rates are determined by the four major glands: thyroid, pituitary, thymus, and gonads. When these glands function normally and their work is balanced, then growth proceeds normally. Did you know that every morning we are taller than the previous evening, but decrease in stature during the day?

Random interesting fact from the Great Encyclopedia:

Why do birds sing?

The bird songs and calls we hear in the spring are part of their love games before mating. Males sing to attract the attention of females. When the male and female find each other, he begins to ruffle her feathers and sing even louder. Females of some breeds of birds answer the male with their songs.

Not all birds are songbirds. There are some, like the stork and the pelican, that seem to have no voice at all. The vocal organs of birds are slightly different from ours. In humans, the vocal cords are located in the larynx, at the top of the windpipe. The simple membrane of birds is located at the bottom of the windpipe, in a part of the body called the lower larynx. This membrane vibrates.

The reason that different breeds of birds sing differently from others lies precisely in the shape of the lower larynx, in the number of muscles that set the membrane in motion. Birds make other sounds besides singing. They exchange cries, signals, disturbing sounds, while understanding each other. If a snake appears near the nest, the bird resorts to an alarm signal. At this signal, flocks of birds flock to her for help.

Birds use various signals and sounds all year round, and they sing only during the nesting period. Bird singing differs in pitch, rhythm, quality. The thrushes are recognized as the leaders in the creation of "real" songs.

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 ... >>

Wireless DVD drive for smartphones 27.11.2017

The Japanese company IO Data has introduced a rather interesting novelty - an external optical drive DVRP-W8AI2, designed for use with smartphones and tablets.

Data exchange between the drive and the mobile gadget is carried out via Wi-Fi wireless communication: IEEE 802.11ac/n/a/g/b standards are supported. Thus, owners of smartphones and tablets are able to view multimedia materials stored on optical discs on the screen of their device.

To operate the drive, you must install the accompanying mobile application. We are talking about support for operating systems Android 4.2.2 and higher, as well as iOS 8 and higher.

The drive can read CD and DVD media. It is also possible to record audio discs. During operation, the device must be placed horizontally.

The novelty receives power from the mains through an adapter. You can also use a portable rechargeable battery, which will have to be purchased separately. Dimensions are 145 x 168 x 19 mm, weight - approximately 430 grams.

The optical drive DVRP-W8AI2 will go on sale in the near future for an estimated price of 120 euros.
