Parce que vous imaginez bien que le chercheur physicien Denis Rancourt connait parfaitement bien l’effet des forces de Van der Waals.

 Vous détournez d’une manière pitoyable le sujet. Les masques ne fonctionnent pas pour éviter la propagation des virus respiratoires aérosols.

Effet de Van der Waals, ou pas, les recherches scientifiques sont incapables de démontrer l’efficacité des masques ! 

Une méta-analyse, qu’il vous faudra « contrer ». Bonne chance ZXSpect !
