Which tree is the tallest?

Trees are green plants. They, like other green plants, have roots, stems, leaves, and seeds. Trees are the oldest of all green plants. Some sequoias in the northwestern United States are over 4000 years old. This means that they were already mature trees when Columbus discovered America. Trees are also the largest of the green plants.

It is known that the tallest on earth are giant sequoias in California. In the Humboldt National Forest there is a tree that is considered the tallest in the world. It is called the Founder's Tree and is over 110m high. Some big experts believe that many years ago the eucalyptus tree in Australia was as tall as these California sequoias, but now they are on average 15 m lower.

Another tree species that approaches sequoias is the Douglas fir, many of which are over 91m tall. Tree roots not only absorb water and minerals from the soil, but also hold the tree to the ground. And to hold a very large tree, a strong root system is needed. Did you know that the root system of a tree takes up as much space in the soil as its crown in the air?

Scientists have learned to count how old a tree is by its rings on the trunk. There are rings in the cross section of most tree species. A layer of new wood forms over a layer of old wood under the bark each year. This layer forms a ring. Each ring in the tree trunk testifies to one year of his life. The trunk gets thicker and thicker as new rings, or layers, are added. In trees, rings are added not only in the trunk, but also in the branches. The branches grow a little in length each year. And since only the ends of the branches grow in height, the bases of the trees never rise higher from the ground than they were at the beginning.

Random interesting fact from the Great Encyclopedia:

Can it be artificially made to rain?

Yes, but in a relatively small area. If necessary, for this, powders of certain substances are sprayed from aircraft, which cause the ice crystals to melt in the clouds, and the water from them falls in the form of rain. It is also possible to temporarily reduce cloudiness for this purpose, other chemical reagents are sprayed.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

Microsoft data center at the bottom off the coast of Scotland 08.06.2018

A data center (DPC) typically generates a lot of heat and noise, and its location may be less than optimal. The solution to all three problems can be underwater data centers created by Microsoft as part of the Natic project.

After a long testing of prototypes, the developers put into operation the first trial center of its kind. The data center, the size of a standard 40-foot container, was towed out to sea off the coast of Scotland, loaded and secured to the seabed. The sealed enclosure contains 12 racks with 864 servers already handling workloads. In addition, a cooling system is mounted in the case, but it is much simpler than that which would be required in the traditional placement of the data center. When operating at full load, the center consumes almost 0,25 MW. Energy is supplied by cable from a wind farm located on land. Fiber optic connections are used for data transmission.

Over the next 12 months, project participants will carefully monitor all indicators - from energy consumption and humidity inside the case, to temperature and noise levels, as well as assess the impact on the environment. According to their plan, the underwater data center will be able to operate without maintenance for five to ten years.

Living offshore may seem counter-intuitive, but more than half of the world's population lives within 200 km of a coastline - an area with rich renewable energy potential. By locating data centers here, it is possible to provide local communities with high-speed access to online services. In addition, deployment is relatively fast. So if all goes according to plan, Project Natick could be the beginning of a transformation in how we deliver online resources to consumers.
