A copy of which country with all cities and terrain exists in Minecraft?

In April 2014, the Danish government made a copy of their country in Minecraft. For this, geodata were used, which are already in the public domain for Danish citizens. The map recreates not only natural landscapes, but also cities with buildings - albeit with flat roofs and random colors of facades. The map is as close to reality as possible due to the fact that the highest point in Denmark is 171 meters above sea level, and the Minecraft engine allows you to build blocks up to a height of 192 meters. Shortly after launch, cases of vandalism were recorded - although dynamite was banned on this server, players discovered that it could still be blown up by putting it inside a mining car.

 Random interesting fact from the Great Encyclopedia:

What elementary particles are named after the cry of ducks?

Murray Gell-Mann, who hypothesized that hadrons are composed of even smaller particles, decided to call these particles the sound that ducks make. The novel Finnegans Wake by James Joyce helped him shape this sound into a suitable word, namely the line: "Three quarks for Muster Mark!". Hence particles are called quarks, although it is not at all clear what meaning this previously non-existent word had for Joyce.

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 ... >>

Crystals that change shape 20.09.2020

The crystals, created by an international team of researchers led by Xi Chen at the City College of New York and his co-authors at the Center for Advanced Science in Crystals, can transfer energy from evaporation into mechanical motion. Thus, evaporation can be a source of energy for actuators, artificial muscles, and many applications.

Unlike traditional crystals, which are usually hard and brittle, new crystals have the ability to change their shape due to their molecular architecture. Crystals are composed of a pattern of small pores punctuated by connecting flexible domains that repeat throughout the crystal structure. The pores passing through the crystals are strongly associated with water molecules.

"When evaporation causes water to be removed from the pores, it causes the entire crystal to be severely deformed through the network junction. The resulting shape change is reversed when water vapor is reintroduced," said Chen, study author and assistant professor of chemical engineering at the CCNY Grove School of Engineering. "Our peptide crystals enable direct observation of water-material interactions at the molecular level using existing crystallographic, spectroscopic and computational techniques. The trigger mechanisms identified are applicable more generally to material designs or structures that make efficient use of evaporation."

The materials that control this movement react to water or humidity. These materials, which swell and contract in response to changes in humidity, can directly and efficiently convert evaporative energy into mechanical motion. This new area opens up opportunities to access untapped water evaporation as an energy source, as well as to develop better actuators and artificial muscles for modern engineered systems.
