Today, the phone can be used for contactless payment for purchases
April 3, 1973 American inventor Martin Cooper created the first portable phone - a mobile phone.
On this day, the world celebrates Mobile Phone Day. Almost half a century after the invention, the mobile device has mastered many new applications and has become something more than just a method of communication. In the company Mastercard made infographics about how and when the mobile phone "learned" to pay.

Ulefone has announced a stand for wireless charging UF002. It uses Qi, the most common technology in this area, which allows you to charge with it almost any device that supports wireless charging. Models that support the fast version of Qi, UF002 charges with a power of 10 watts, others - 5 watts. The device is built-in protection against overheating, overcharging, excessive voltage and so on. Ulefone worked on the design of UF002: a leather surface, a metal frame for greater strength, non-slip gaskets. The stand weighs only 85 g, which makes it convenient for carrying. The price is still unknown.

Scientists from the US found a topological order in artificial spin ice - a collection of nanoparticles of oblong form, located in a two-dimensional lattice of shakti. According to physicists, they were the first to discover such phases in classical systems, and not in quantum systems.
Artificial sets, such as artificial spin ice, were previously found exclusively outside the functioning of the thermodynamic theory. In quantum physics, there are other rules that do not conform to Newton's laws. Scientists refer crystals to ordered substances, and gases to disordered ones. According to experts, the transfer of topological effects to thermodynamics entails the possibility of conducting additional studies in artificial spin ice.
Earlier similar phenomena could be noticed only in quantum systems. Therefore, physicists call the discovered discrepancy with the universally recognized scientific rules a unique opportunity to make stunning discoveries in the future.

American scientists have created a miniature recording device, which is about 10 trillion times smaller than the person's ear, but at the same time is not inferior to it in sensitivity, RIA Novosti reported.
The "recipe" for its assembly was published in the journal Science Advances.
"Our nano-membranes not only have a very high sensitivity for their size and weight, but they consume very little energy and almost do not" rustle. " Ultimately, they will allow us to create devices that work equally well with clean and powerful signals, and with a high level of noise, "said Philip Feng of the Case Western Reserve University in Cleveland, USA.
Almost all modern digital gadgets include miniature microphones, accelerometers and pressure sensors, whose dimensions are ten times smaller than those of human eardrums and other living things. Such devices, built on the basis of so-called microelectromechanical systems (MEMS), quite well perceive sound, but are characterized by low accuracy of operation and sensitivity.
