Why do large marine ships have a rounded thickening in the bow of the underwater part?

The so-called "bulb", which in a fully loaded ship is under water, serves to better flow around the ship's hull and, consequently, to reduce the resistance of water to the movement of the ship. Its speed increases, and energy costs decrease.

This protrusion is available on all cargo ships.

Random interesting fact from the Great Encyclopedia:

What is atomic energy?

Atomic energy is energy derived from an atom. Every atom is made up of particles of energy. This energy holds all the particles of an atom together. Therefore, in atomic energy, the nucleus of an atom is the source of energy. This energy is released when an atom splits.

In fact, there are two ways to obtain energy from an atom. The first is a fusion reaction, the other is a fission reaction. In a fusion reaction, two atoms fuse together to form a single atom. When atoms combine, enormous energy is released in the form of heat. Most of the sun's energy comes from a fusion reaction that takes place in the sun. This is one of the types of atomic energy.

The second way is a fission reaction, or splitting. Fission occurs when one atom splits into two. This happens when atoms are bombarded with particles of atoms, for example, neutrons (it is part of the atom).

Not every bombardment of an atom leads to its splitting. Most atoms cannot be split. But the atoms of uranium and plutonium decay under appropriate conditions.

One of the types of uranium - uranium-235 (it is also called an isotope of uranium) is split into two parts when bombarded with neutrons. Can you imagine how much energy this releases? One kilogram of uranium-235 releases a million times more energy than the combustion of one kilogram of coal. A small piece of uranium can power an entire ocean-going ship, aircraft, or generator. As you can see, atomic energy can serve as the main source of energy for mankind in the future.

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Samsung 8 GB LPDDR4 mobile memory modules 21.10.2016

Samsung Electronics has announced the release of 4 GB low power, double data rate 4 (LPDDR8) mobile DRAM modules. As CNews was told by the company, the new solution is focused on working in mobile devices with large Ultra HD displays. The 8GB DRAM module houses four 16Gb LPDDR4 memory chips manufactured using a 10nm process.

"The launch of the powerful new 8GB mobile DRAM module will lead to higher performance next-generation flagship mobile devices around the world," said Yoo Sung Choi, executive vice president of Samsung Electronics Memory Marketing and Sales. storage that meets the growing needs of the latest devices with features such as dual cameras, 4K UHD video and virtual reality technologies."

The data transfer rate of the new LPDDR4 8 GB module reaches 4266 Mbps, which is twice as fast as DDR4 DRAM for PCs, which is typically around 2133 Mbps. Provided that the memory bus width is 64 bits (x64), this guarantees data transfer at a rate of up to 34 GB per second.

Dimensions of 8 GB LPDDR4 are less than 15x15x1 mm, which meets the size requirements of most modern ultra-thin mobile devices. Depending on the manufacturer's preference, a sub-1mm thick DRAM stack can be used in conjunction with a general purpose flash drive or a mobile processor to save PCB space.

In August 2015, Samsung introduced the first 4GB LPDDR12 DRAM solution on the market in 20nm. The development period for the new 16GB LPDDR4 DRAM solution in 10nm process technology, as well as 8GB LPDDR4 DRAM, was 14 months.
