Are there time zones around the world?

Today, when we cover huge distances with the help of jet aircraft, the difference in time surprises us even more. If we fly from New York to Los Angeles, then we arrive at the final destination at almost the same time.

The fact is that the territory of the United States is divided into time zones. This decision was made in 1833, when the United States was divided into four time zones - eastern, central, mountainous and Pacific.

This division took place along the meridians - imaginary lines that run along the surface of the Earth and connect the North and South Poles. The time difference of each zone was one hour. Within the zones, the time was the same.

When moving east from one time zone to another, time is added by an hour, when moving west, it is also reduced by one hour. But time zones do not have direct boundaries. The fact is that some areas located close to each other expressed a desire to have the same time. For example, the states of Georgia, most of Florida, and southern Michigan were supposed to be in the central zone, but they exist in eastern zone time.

The entire territory of the globe is divided into time zones, like the United States. Each time zone is 15 degrees along the meridians. Where do the meridians start from?

It starts in the UK, in Greenwich. It is the prime meridian. If you move east from Greenwich, one hour is added to Greenwich time every 15 degrees. When moving west, one hour is deducted accordingly.

So, if it's 12:00 in Greenwich, it's 4:00 in the morning in California, since you've crossed nine 15-degree sections to the west. In Egypt at the same time 14:00, as we crossed two 15-degree intervals to the east.

On the opposite side of the Earth from Greenwich there is an imaginary "Date Line". If we cross it and move west, we lose one day, if we cross it and move east, we "gain" one day as well.

Random interesting fact from the Great Encyclopedia:

Can cats really see in the dark?

No animal can see in complete darkness, but cat eyes are much more adapted to very low light conditions than the eyes of most animals.

The fact is that on the inner surface of the choroid of the cat's eye there is a shiny layer (tapetum, or mirror). It reflects light onto the retina and thereby enhances the light irritation of the visual cells, increasing their sensitivity in low light.

The same shiny layer causes the cat's eyes to seem to glow in almost complete darkness.

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 ... >>

sea bus 03.03.2005

The British company "Covelink Marine", engaged in the production of amphibious all-terrain vehicles, has developed a floating bus with 28 seats.

A diesel engine with all-wheel drive allows it to reach speeds of up to 110 kilometers per hour on a good road, and after launching, a jet propulsion unit is turned on, accelerating the sea bus to 55 kilometers per hour. Options are produced for the military, customs officers, rescuers, lovers of tourism, hunting and fishing.
