Who discovered Greenland?

If there is a place on earth that you would not even think of calling green, it is Greenland! Most of Greenland is covered by an ice shell, reaching more than 3000 meters thick in some places. Only the most resilient plants and animals can survive in such a climate on the edge of the ice sheet. Winters are very cold here, and summers are short and cool. Only small patches of land are covered with grass, heather and low flowering plants. Most of the ice-free surface is barren rocks covered with mosses and lichens.

Why then was this place called Greenland? Yes, for the same reason that an entrepreneur, wishing to attract buyers, gives the name "Pleasant Hill" or the like to a place that is really completely unattractive. In 982, an Icelander named Eric Thorvaldson ended up in southwestern Greenland. This stern man, better known as Red Eric, was exiled from Iceland for three years for killing a man. Erik spent three years in exile, exploring the western lands described by Icelandic sailors.

Three years later he returned to Iceland and told people about his research. He really wanted the settlers to rush to this country, so he gave it such an attractive name - Greenland! Today, less than 55 people live in Greenland, which is very small for such a large area. Most of the population lives on ice-free areas of the island on the southwest coast. Only 3260 people live in eastern Greenland and fewer than 800 live in the north.

Random interesting fact from the Great Encyclopedia:

Why is it cooler at the top of the mountain?

Our atmosphere is divided into layers, they are all different from each other. The main layers are called the troposphere, stratosphere and ionosphere. Together they form a cover several kilometers thick. The troposphere is the lowest layer of the atmosphere where we live. The upper limit of the troposphere is at an altitude of 11 m above sea level. Above the tropics it is higher (000-16 km), above the poles it is lower (18-8 km).

Instruments raised on balloons prove that the temperature in the troposphere is gradually falling. The higher you go in the troposphere, the colder the temperature becomes. Every 300 m the temperature drops by 2 °C. So when we go up in the mountains, we go up in the troposphere. Therefore, at an altitude of 1,5 km in the mountains it can be 8 ° C cooler than at the foot.

And there are peaks that reach a height of more than 8 km! No wonder it's very cold there. In the upper troposphere, the temperature is almost 60 degrees below zero. It is always warmer near the surface of the Earth. The reason is that the Sun heats the Earth and the Earth releases this heat into the air. The sun does not heat the atmosphere directly. In the highest layer, the ionosphere, the air is rarefied, atoms and molecules are exposed to solar radiation.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

New temperature sensor for computer memory modules 26.12.2006

Maxim Integrated Products introduced the MAX6604, a small, low-cost temperature sensor designed to monitor the thermal behavior of DDR memory modules.

This device measures temperature with an accuracy of +1°C, converts the measured value into digital format and transmits it via a PC-compatible interface. The MAX6604 monitors the temperature continuously and updates the data eight times per second. This method improves performance by providing a highly accurate measurement of module temperature. Analogues that use readings from sensors installed on motherboards to estimate the temperature of memory modules are much less accurate. The MAX6604 is available in miniature TDFN and TSSOP packages.

The device contains a three-address bus, which provides a choice of eight possible addresses. The combination of these features makes the MAX6604 an ideal choice for high performance notebook memory modules. The MAX6604 operates in a temperature range of -20...125°C and a supply voltage of 3,0...5,5 V. The LP3906 module is available in a 4x5mm 24-pin package.

The device has two high-efficiency regulators with a working current of 1,5 A and linear regulators with a working current of 300 A with a PC-compatible interface. The voltage regulators have a dynamically programmable voltage level from 0,8 V to 3,5 V with an efficiency of 96%. Linear regulators have a dynamically programmable wide-output voltage level from 1V to 3,5V.

Applications: broadband processors, peripheral processors (video and audio), I/O power, digital signal processors, programmable logic chips.
