Technological metals – Term introduced in 2007
Technological metals – A concept that is relatively new, in contrast to the actual use of metals in science and industry. The date in 2007 was introduced by American chemist and physicist Jack Lifton. Since then, it is often used in industry. Generally, you can say that the tech. metals are basically precious metals and those that are necessary for the production of hi-tech devices and engineering systems. This category includes:
- commercial production of miniature electronic devices li>
- advanced military systems li>
- generating electricity using alternative sources, for example solar panels or wind turbines li>
- electricity storage using batteries and cells. li>
There are of course a lot of other uses of these elements. Almost all technological metals are a by-product of the treatment of basic metals (except for precious and lithium).
Supersensitive cameras – Detects threats for Earth
Supersensitive cameras – Will be the heart of the NEOSTEL ground-based telescope, whose task will be to detect dangerous for Earth objects. It will be part of the space situational awareness system (SSA) created by the European Space Agency (ESA). It’s about supervising space and tracking space objects. The NEOSTEL ground-based telescope is designed to help you with tasks that can detect various threats to objects Earth. The heart of the telescope will be the super sensitive CCD (Charge Coupled Device) cameras used for astronomical observations. Creotech Instruments S.A. is responsible for the development and production of cameras.
The cameras are cooled down to -50 ° C and maintained in a similar environment to the vacuum, so that when installed on the telescope it can observe the object of the size of a tennis ball, from a distance of 1000 km. This will not only detect asteroids that threaten Earth, but also space debris that can threaten functioning satellites and damage or destroy International Space Station (ISS).
VR may cause vomiting – Because of motion sickness
VR may cause vomiting – Because of motion sickness – In order to fully enter the virtual reality,
one has to deceive not only the eyes but also the other senses. This is also the reason why
many virtual reality users can cause problems with motion sickness. Then the impressions
received by the liar do not agree with the visual stimulus. In motion sickness,
the eyes see that the body is not moving, and that the labyrinth registers continuous motion,
tilting and acceleration, in the case of nausea caused by virtual reality is quite the opposite.
Eyes see the perfect simulation of space, covering the entire field of view.
However, the brain does not record any motion signals from the labyrinth or other senses.
In both cases there is a sensual dissonance that causes malaise, dizziness, fatigue,
and even vomiting.
Thomas Alva Edison
Thomas Alva Edison – In 20.12.1880 American explorer and inventor Thomas Alva Edison,
presented the light bulb with carbon filament.
First photographing method – Invention of daguerreotype
First photographing method – Invention of daguerreotype – In 01.09.1839,
the French Academy of Sciences announced the invention of the daguerreotype,
the first shooting method. But it was a very expensive method. Which did not give the
possibility of obtaining multiple copies of a single negative.
John Harrison – English carpenter and watchmaker
John Harrison – English carpenter and watchmaker – In 24.03.1693 born
English carpenter and watchmaker J. Harrison. Creator of the first clock (chronometer),
used on ships and helpful in determining longitude. He was involved in the construction
and modernization of clocks. One of the first chronometer weighed 34 kg, one of the last 1.5 kg.
Memory USB PenDrive – Flash memory
Memory USB PenDrive – It is a memory device, having the flash memory, which stores data also when power is disconnected. Commercial production was launched in 2000. The first devices of this type have a capacity of 8 MB. At present, it ranges from 1 GB to 256 GB.
3d printing in space
3d printing in space – In recent years, significantly improved technologies for printing three-dimensional objects that are already much cheaper. The company Made in Space has launched a project. Allowing to print 3D components, directly on orbit.
GPS system – It uses 31 satellites orbiting the Earth. Each is equipped with an atomic clock and emits signals in which encoded is its location and the clock. Satellites are close to 20 thousands km. above the Earth. The attraction is there so much weaker satellites clocks ahead of the Earth about 38 millionths of a second a day. To get the accuracy of 10-15 meters, the GPS receiver needs to know the super-accurate time transmission of the satellite signal. Error no greater than 50 nanoseconds.
Electronic nose – Detects and analyzes smells
Electronic nose – E-nose is a device that detects and analyzes smells. It successfully replaces the human organ of smell, eg. When assessing the quality of the product.
