Who Invented the Accordion?

The accordion is an instrument made on the principle of bellows. The sound in it is produced by forcing air passing through metal plates. The development of this tool has been going on for many years. For the first time, metal plates that are part of the instrument were used by the ancient Chinese in a musical instrument called "cheng".

In the XNUMXth century, the idea came up to use wooden frames on furs. When stretching and compressing the bellows, a stream of air appears, due to which the plates vibrate. The keys of the records are pressed. The vibration of these records produces the sounds of the accordion. The keys, which are used not only in accordions, but also in the piano, were invented in the XNUMXth century.

The first instrument that can be considered the ancestor of the modern accordion was made by an Austrian named Damian in 1829. The concert accordion, as it was called, until 1910 was known only in European countries. Then he appeared on the American stage. Since that time, it has been significantly improved and in 1937 it was first used in a symphony orchestra.

The concert accordion has 120 bass keys on one side and 41 high keys on the other.

Who invented the elevator?

The elevator was not invented by any one person, but this idea has been developed over a long time. Mechanisms operating on the principle of an elevator have been used for many centuries.

The ancient Greeks lifted objects using blocks and winches. A block is a wheel with a groove along which the rope slides. A winch is a mechanism with a wider wheel or drum to which the end of a rope is attached. When turning the drum with a handle, the rope is wound or unwound from the drum. If the rope is passed through the block, it can raise and lower the load.

In the XNUMXth century, the "flying chair" was invented. It was designed to lift people to the upper floors of buildings and was driven by a system of weights and blocks. The chair and its mechanism were outside the building. However, the "flying chair" has not found wide application. In the first half of the XNUMXth century, the elevator already existed, but was used mainly for lifting goods.

Later, a steam engine was used to turn the drums of these hoists. Most of all, people were afraid that the ropes holding the elevator might burst, and the elevator would fall down. But when Elisha Otis invented accident-proof safety devices, elevators became very popular. At the same time, hydraulic lifts began to be used to raise and lower cabins, which use high-pressure fluid.

The electric elevator we use today was invented by the German engineer Werner von Siemens.

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

Implanted brain stimulator 30.04.2024

In recent years, scientific research in the field of neurotechnology has made enormous progress, opening new horizons for the treatment of various psychiatric and neurological disorders. One of the significant achievements was the creation of the smallest implanted brain stimulator, presented by a laboratory at Rice University. Called Digitally Programmable Over-brain Therapeutic (DOT), this innovative device promises to revolutionize treatments by providing more autonomy and accessibility to patients. The implant, developed in collaboration with Motif Neurotech and clinicians, introduces an innovative approach to brain stimulation. It is powered through an external transmitter using magnetoelectric power transfer, eliminating the need for wires and large batteries typical of existing technologies. This makes the procedure less invasive and provides more opportunities to improve patients' quality of life. In addition to its use in treatment, resist ... >>

The perception of time depends on what one is looking at 29.04.2024

Research in the field of the psychology of time continues to surprise us with its results. Recent discoveries by scientists from George Mason University (USA) turned out to be quite remarkable: they discovered that what we look at can greatly influence our sense of time. During the experiment, 52 participants took a series of tests, estimating the duration of viewing various images. The results were surprising: the size and detail of the images had a significant impact on the perception of time. Larger, less cluttered scenes created the illusion of time slowing down, while smaller, busier images gave the feeling of time speeding up. Researchers suggest that visual clutter or detail overload can make it difficult to perceive the world around us, which in turn can lead to faster perception of time. Thus, it was shown that our perception of time is closely related to what we look at. Larger and smaller ... >>

New file system for Windows 8 20.01.2012

Microsoft's new file system will offer much more flexible storage and data integrity than NTFS, which turns 20 next year.

Microsoft has introduced a new file system for computing machines on the Windows platform. It was called Resilient File System (ReFS), which can be translated as "Fault Tolerant File System". Microsoft Vice President Steven Sinofsky said in a corporate blog that since they are "reinventing" Windows with Windows 8, this approach should also apply to data.

ReFS uses the basic principles of NTFS, the most popular file system on the market, introduced about 19 years ago. However, the new system was created from scratch, according to the official blog. The main goal: support for future generations of storage systems and new scenarios for working with information.

When developing ReFS, the engineers pursued the following tasks: to borrow all the best from NTFS and cut off all the difficult moments (for example, data compression and quotas were excluded); enable the system to validate and automatically correct data, maximize scalability, enable system uptime by isolating problem areas, and enable new Storage Spaces technology.

The Storage Spaces technology introduced a few days ago allows you to create single logical spaces for storing data from several drives with different connection interfaces, for example, "Documents", "Multimedia", "Archive", etc. At the same time, it is possible to connect an additional drive to the space at any time to increase the total capacity.

With the new file system, data integrity is prioritized
ReFS will allow you to detect the loss of data fragments and incorrect addressing of fragments - using checksums. It will also add technology to track degraded data ("bit rot") - the type of loss that is most difficult to notice. Data degrades due to the fact that the cells of the drive are used unevenly during operation. To identify such fragments, a process will be added to the operating system that will regularly compare data with data in backups and identify discrepancies.

If files are corrupted and cannot be restored from a backup (for example, if the system damaged all copies of a file due to some error), it will be automatically removed from the namespace. Thus, it will be "cut off" from the OS and will not cause subsequent failures.
