Scientists discover previously unknown human abilities
Austrian scientists have been able to prove in practice that the human eye is able to perceive single particles of light. Previously, a significant part of the scientific community was of the opinion that the human senses are extremely imperfect "devices" for understanding the environment. Recently, however, more and more experiments are being carried out that open new limits for the sensitivity of human organs.
Austrian scientist Jonathan Tinsley from the University of Vienna and his colleagues discovered the ability of the human eye to see a single photon. A number of volunteers reacted to the operation of a quantum generator, which released single photons. According to the results of the experiments, it was found that when single photons are launched in pairs, a person will not notice the first particle of light, but in some cases he will notice the second light quantum. The number of such outcomes is about 6%, however, this indicator also confirms the ability of the human eye to record photon flashes.
It is worth recalling that a year earlier, scientists managed to experimentally prove that the human eye is able to find differences in the size of microscopic objects. Even more surprising was the fact that the "fission rate" with this method of fixing the size of the object reaches only one nanometer. German scientists came to this conclusion after a series of experiments with light streaks on the surface of nanofilms.
