The internet has been made many things safer. But it's a dangerous place.

Students are told not to use Wikipedia in research, but it's trustworthy. Says the article in "The Conversation".  The link to the article is here . But you can see the URL below this text.  The prohibition of using Wikipedia as a source for research is one of the most interesting questions in the studies. In normal cases the Wikipedia is trustworthy. And some people are saying that the purpose of that prohibition is to make work more difficult than it is.  The thing is that Wikipedia is trustworthy in the cases like computing and natural sciences. But there are also problems with the things like selecting sources for the works in the modern world. Things like books are good sources if they are confirmed. But the fact is that during the time of the internet the printed information might be old.  When books are coming to bookstores they might handle the old-fashion information. And that thing is visible in the most intensive areas like computing. The things that peopl...

Photocatalysis: the proton transfer between titania surface and dye observed

"When the titania and the dye adsorbed on its surface are irradiated with a femtosecond pulsed laser proton transfer from the dye molecules to the titania surface, the fluorescence of the deprotonated dye is observed.

Copyright 2021 American Chemical Society."(https://scitechdaily.com/photocatalysis-evaluation-proton-transfer-between-titania-surface-and-dye-observed/) Today there was an article in the SciTech Daily about the protonic interaction between the titania layer and dye offered to make the new type of solar panels. In image two is the diagram of that kind of interaction. The thing is that increasing the number of protons on the layer. That thing increases the electronegativity of the layer. And that thing increases the flow of electrons.  But the proton interaction offers to make many other things than just create electricity. Increasing the electronegativity wo...

Fusion power is far away in the future.

Image: Pinterest Originally, the image above this text portrayed a donut-shaped space station called "Stanford torus". But it can also portray the donut-shaped power satellite, that uses the "Tokamak-type" nuclear reactor. This type of power station could deliver energy to the futuristic space stations that orbit Jupiter and other planets in the distant future.  The power satellites or zero-gravity conditions can solve some of the problems of the fusion reactor. The zero-gravity conditions are making it easier to control the high-energetic plasma. That orbits in the donut-shaped reactor.  At the beginning of this text, I must write about one of the most futuristic solutions for energy production. That thing is the energy satellites. The giant power stations that are orbiting Earth and deliver energy to the ground by using radio, laser rays, or targeted microwaves. The problem with those satellites is that they are easy to turn to weapons. And powerful microwaves or ...

The mixed reality is a powerful tool for many things.

The idea of mixed reality is that this kind of system can combine the real world with VR (Virtual Reality). The simplest idea is to make the robot that sends things what it senses to the controller. The robot's eyes would be the camera systems that are connected remotely to the VR glasses.  The ears of the robot are microphones. And they are sending data to the gamer's headset. The touch sense is the pressure detector that sends the feel of touch to the data gloves. Then the operator can interact with the physical robot. And that thing allows making safely many things that are very risky for the people. If we are thinking about the cases like nuclear accidents. And sadly battlefields those robots can use many types of communication systems. If the robot is inside the powerful electromagnetic field that can close the radio communication it can change to use laser-led for sharing data.  There are many types of interfaces that allow robots to operate very effectively. Those syste...
