What is the purpose of daylight saving time?

Imagine that we get up at 7:00 in the morning and fall asleep at 23:00. Arriving home from work at about 18:30, we have dinner and are free after 20:00. It is already dark to go outside and rest. There is no time at all to enjoy a summer day.

Now imagine that we have moved the clock forward by one hour. A person does everything at the same time - but now, when he goes out in the evening at 20:00, there is still enough daylight time to relax. He "won" an hour of daylight!

Of course, daylight saving time does not add hours to the day. This is impossible. This is done in order to increase the number of hours during daylight hours, when the sun rises very early.

Summer time is especially convenient for city dwellers. It allows you to close shops, offices, factories at the end of the working day, when the sun is still high enough. Farmers and peasants who work by the sun usually do not switch to daylight saving time. They cannot work in the field until the morning dew has dried up or after it appears in the evening.

Do you know who invented daylight saving time?

Benjamin Franklin! In the XNUMXth century, while in France, he proposed this innovation to the Parisians, but they did not accept it.

Daylight Savings Time was first adopted during the First World War. At that time, there was not enough fuel to produce electricity, so it was necessary to save it. With the adoption of daylight saving time, many go to bed immediately after dark, while without it, if they had to stay awake until that time, it would be necessary to use electricity.

In 1915, Germany was the first to adopt daylight saving time, in 1916 it was done in England, in the USA - in 1918.

 Random interesting fact from the Great Encyclopedia:

Why is it good to sleep in the middle of the day?

Currently, physiologists believe that a person should sleep not once, but at least twice a day. They have proven that a short nap in the middle of the day improves concentration and productivity.

So, for example, the speed of visual reaction (the time during which a person understands what is written on a computer screen) in the morning is 10 milliseconds, in the evening - 40. But if the subject slept during the day, then in the evening he perceives information as quickly as in the morning.

In favor of the expediency of daytime sleep, the fact that a person’s temperature during the day is not constant, but has two minimums - in the intervals of 3-5 and 13-15 hours. It is at this time that most people have the strongest desire to sleep.

This pattern is explained by the fact that our ancestors, primates, inhabitants of hot tropical countries, are mainly twilight animals, they are especially active at dusk, in the evening and in the early morning. And in the middle of the day, at the hottest time, they sleep under the canopy of dense crowns.

First in Japan, then in Europe, and now in the United States, many firms have begun introducing daytime naps. In the German town of Vechta near Hamburg, municipality employees can get 20 minutes of sleep a day if they wish. In order not to hire additional employees, the mayor's office decided in this way to increase the efficiency of the existing employees.

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 ... >>

Beats Electronics Powerbeats2 Wireless Headset 23.06.2014

Beats Electronics, which recently became part of Apple, announced the release of an updated headset for athletes called Powerbeats2 Wireless. This is the first wireless headset from Beats Electronics. Bluetooth is used to connect the headset to a mobile device. The headphones are connected to the remote control and the microphone with a flat cable.

Like the previous Powerbeats model, the novelty was created by the joint efforts of Beats specialists and the famous basketball player of the Miami Heat club LeBron James. The device is also made in the in-ear form factor with an adjustable rubberized earpiece for attaching behind the ear.

The headset is designed for fitness enthusiasts. The press release noted its resistance to moisture and sweat in accordance with the requirements of the IPX4 standard.

In addition to listening to music, Powerbeats2 can be used instead of a regular Bluetooth headset for telephone conversations. Unlike most Beats Electronics products, the novelty is lightweight. However, as the company assures, the device provides the same high quality sound as its predecessor Powerbeats. The headset has a volume control and a track switch button.

The Powerbeats2 has a battery life of around six hours, making it suitable for long-distance runners as well. It also reports the possibility of fast charging within 15 minutes, ensuring continuous operation of the device for an hour.

The Beats by Dre Powerbeats 2 Wireless goes on sale this month for $199,95.
