An interesting discussion on the Fleming radio 1 : scientists managed to create light that moves as a spiral. To know more about it, listen to the program (in Dutch). Why can this be important? What can be done with this?   You should also know that light is an electromagnetic radiation of a wide range of different wavelengths that results in different kinds of visible and invisible light but at the same time is also particle-like consisting of discrete packets of energy, i.e. photons, the so-called wave-particle duality . This means that light moves as a wave but only hits something in one place with a certain energy that can be sufficient to move very small things such as molecules. This is different from a wave at the beach that reaches the coast over a certain distance although also with a particular energy.   Possible scope of spiralled light -  Thalidomide as example Softenon with active substance thalidomide was used as an example how this light m...

Dead and violence in USA President Trump says Minnesota's mayor is a weak person but I don't think so as he dared to fire four of his police officers after one of them put his knees for about 8 minutes on Mr George Floyd, a black man, his throat until he was death. The president didn't dare or didn't want to condemn the officers while in a tweet threatens that looters will be shot (such tweets should not be deleted as some claim but instead warn people but also intelligence agencies so they can intervene).   Indeed, violent clashes broke out after the video made the arrest public. It is even worse because Mr Floyd was already handcuffed and thus limited in his movements while he didn't seem to fight against his arrest. Other videos suggests the knee on someone's neck is likely a normal way to restraint someone until they are handcuffed (and thus not until they are dead) but can no longer be used. Thus, this incident will further increase distrust between...
