What translation inaccuracy caused the emergence of the theory of a highly developed civilization on Mars?

In 1877, the Italian astronomer Giovanni Schiaparelli discovered a network of lines on Mars, which he called the word "canali". In Italian, it can mean both natural channels and artificially created channels, but in the translation of his works into English, the term "canals" was used, which applies only to man-made objects. This provoked the emergence of many theories and literary works about a highly developed civilization on the Red Planet. Later it was proved that these channels were just an optical illusion caused by the imperfection of the telescopes of that time.

Where is the restaurant, whose tables are placed between the graves of the old cemetery?

In the Indian city of Ahmedabad, there is a New Lucky restaurant built on the site of an old Muslim cemetery. True, the graves have not gone away - the tables are placed right between them. The owner of the cafe says that this does not bother customers at all, and the business itself is booming. Waiters every day, in addition to serving customers, pay tribute to the deceased - they wipe the graves and sometimes put flowers on them.

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 ... >>

The world's fastest hard drive from Seagate 22.03.2018

Seagate, an American manufacturer of storage solutions, has demonstrated a new ultra-fast hard drive. The design of the device uses Seagate's own "multi-actuator" technology under the Mach.2 brand. It was this solution that made it possible to achieve a twofold increase in throughput compared to drives of the same class. In addition, the company's new drives will record data using a new technology developed by Seagate.

A method that allows to achieve an increase in the level of recording reliability and significantly increase the storage capacity (up to 40 TB) without increasing the number of magnetic platters is called HAMR (thermal assisted magnetic recording).

According to Seagate, the new device meets all modern standards of reliability and durability. The MTBF of HAMR heads is 6 hours, equivalent to 3,2 PB of recorded data and 20 times the industry standard.

The new hard drive will be part of Exos' flagship line for the corporate sector. The price and timing of the appearance of new items on sale are still unknown.

A hard disk drive consists of several platters covered with magnetic material and located on a single axis, as well as a set of heads, the number of which corresponds to the number of platters. The head drive is called an actuator and is generally capable of moving the heads simultaneously, which imposes certain restrictions on the possibility of synchronously performing read / write operations on several platters at the same time.

Seagate solved this problem by dividing the single actuator into two independent head assemblies. This achieved a record sequential write speed of 480 MB/s without increasing the speed of the hard drive spindle, which is more than twice the throughput (235 MB/s) of standard industrial solutions running at 7,2 thousand revolutions per minute.
