In September Google announced some news for Cardsincluding a feature Search with live view. The novelty interactively shows the surrounding places of interest to the user using augmented reality.

From Friday (18) the function is already available to users android e iOS in international cities such as London, Los Angeles, New York, San Francisco, Paris and Tokyo. Although the arrival in Brazil has not yet been confirmed, a solution should appear in the future.

This feature shows data such as classification, opening hours, prices, and even the availability of the establishment, making life easier for users who no longer need to perform these searches outside the application. In addition, an interesting detail will be presented for electric vehicle owners, who will have the opportunity to find charging stations for their vehicles through the app.

Einstein's complete theories are a breakthrough in particle physics

More than a century after its first appearance, scientists have completed Einstein’s homework on special relativity in electromagnetism.

Osaka University researchers demonstrate the relativistic contraction of the electric field generated by fast moving charged particles, as predicted by Einstein’s theory, which could help improve research in particle physics and radiation.

More than a century ago, one of the most famous modern physicists, Albert Einstein, proposed the revolutionary special relativity. Most of what we know about the universe is based on this theory, but some things have yet to be experimentally proven. scientists who Osaka University The Institute of Laser Technology was the first to use ultrafast electro-optical measurements to visualize the compression of an electric field around a beam of electrons moving at close to the speed of light and to demonstrate the generation process.

According to Einstein’s special theory of relativity, it is necessary to use the “Lorentz transformation”, which combines spatial and temporal coordinates to describe the movement of objects passing by the observer at a speed approaching the speed of light. He was able to explain how these transformations led to self-consistent equations for electric and magnetic fields.

Although the various effects of relativity have been proven many times with a high degree of experimentation[{” attribute=””>accuracy, there are still parts of relativity that have yet to be revealed in experiments. Ironically, one of these is the contraction of the electric field, which is represented as a special relativity phenomenon in electromagnetism.

Now, the research team at Osaka University has demonstrated this effect experimentally for the first time. They accomplished this feat by measuring the profile of the Coulomb field in space and time around a high-energy electron beam generated by a linear particle accelerator. Using ultrafast electro-optic sampling, they were able to record the electric field with extremely high temporal resolution.

It has been reported that the Lorentz transformations of time and space as well as those of energy and momentum were demonstrated by time dilation experiments and rest mass energy experiments, respectively. Here, the team looked at a similar relativistic effect called electric-field contraction, which corresponds to the Lorentz transformation of electromagnetic potentials.

“We visualized the contraction of an electric field around an electron beam propagating close to the speed of light,” says Professor Makoto Nakajima, the project leader. In addition, the team observed the process of electric-field contraction right after the electron beam passed through a metal boundary.

When developing the theory of relativity, it is said that Einstein used thought experiments to imagine what it would be like to ride on a wave of light. “There is something poetic about demonstrating the relativistic effect of electric fields more than 100 years after Einstein predicted it,” says Professor Nakajima. “Electric fields were a crucial element in the formation of the theory of relativity in the first place.”

This research, with observations matching closely to Einstein’s predictions of special relativity in electromagnetism, can serve as a platform for measurements of energetic particle beams and other experiments in high-energy physics.
