What is the connection between the SQL code airport and the nearby Oracle headquarters?

According to the international classification, the airport of the town of San Carlos in California has the SQL code. Some IT professionals believe that this has something to do with the headquarters of the Oracle Corporation, located in the nearby city of Redwood City, known for the production of software for working with databases (SQL is the most famous database query language). However, the airport had this code long before the formation of Oracle, so this circumstance is explained by a mere coincidence.

Random interesting fact from the Great Encyclopedia:

Why does water flow from a spring?

The water that flows from the springs once fell in the form of rain. Rain water soaks into the ground and penetrates into the rocky soil through cracks. Of course, some of the water remains at the surface and evaporates into the air, and is also taken up by the plants through their root systems.

The rest of the water, under the influence of gravity, descends as far as the rocky ground allows. Deep underground, at various depths, there are areas where all the voids in the rocky soil are filled with water. Such areas are called "groundwater zone". The upper level of such waters is called the "water level" (boundary of the aquifer).

A spring is formed when there is a natural hole in the ground for water, located below the level of this layer of water. That is why many springs are located in valleys or other low places. Groundwater flows through springs along rocky voids along the bottom or along the slopes of similar lowlands. The spring is also subject to gravity: water flows from top to bottom.

Some springs are fed with water from the aquifer. They operate all year round and are called "permanent". For other springs, their channel connecting the surface with the aquifer is located in close proximity to the upper water level of this layer. Such springs operate only during rains, when the water level rises. They are called "pulsating".

Spring water passes through the rocky soil underground, so it contains some minerals, such as sulfur, lime. Springs, the water of which contains significant amounts of mineral salts, are called mineral springs.

In some areas, especially where there has been volcanic activity, water comes into contact with heated underground rocks. Such sources are called "thermal".

An artesian well is different from a spring. In such a well, rainwater seeps down until it reaches a layer of porous rocks located between two layers of monolithic rocks. This water is under pressure from all sides, and when a well is drilled in this place, the water bursts out with force. The well should be drilled in a place that is below the point where water enters the ground.

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 ... >>

Combat laser HELIOS 20.01.2021

The US Navy received a combat laser for mounting on a warship. The HELIOS system will be installed on the USS Preble (Arleigh Burke class) destroyer during maintenance. Thus, the US Navy will receive the world's only unique combat laser installation for testing in real conditions.

The HELIOS system or high-energy laser with integrated optical blinding and surveillance systems is a composite source of high-quality laser radiation. This is a fiber optic laser based on spectral combining technology, where several individual lasers are combined to form a beam of increased power (almost like the Death Star, but smaller).

The power of the HELIOS plant exceeded 60 kW, which is higher than that stated in the project. By the way, composite lasers are highly scalable, which allows you to create a setup for land, mobile or air-based with its own specific requirements. Similar projects are being developed in other countries, for example, in Germany. For hitting small air and surface targets, this is considered an ideal solution both in terms of saving ammunition, and in terms of speed and accuracy of hitting targets.
