Regional map of average symptoms characterizing COVID-19. Shown are areas in different cities where there are at least 30 respondents, or neighborhoods with at least 10 respondents to the questionnaire. Each area is colored according to a category determined according to the average amount of symptoms reported by the respondents in that area. Green - low percentage of symptoms, red - high percentage of symptoms

Simulation of the experiment in which the first images of a quantum electronic crystal were obtained, the existence of which was predicted 80 years ago. The researchers saw electrons arranged as pearls in a string (red balls) along a nanowire. To observe the electrons without affecting them, a single electron (in green) carried by another nanowire was used as a sensor (scanning detector) that detected the electric fields created by the electrons in the crystal
