Corona Regulations and the Monster of Loch Ness: What is it All About?

Abstract

The author, writing as an independent scientist, examines the scientific basis of two Corona measures made mandatory in many countries: surgical masks for the general public and CO2 meters in pubs, restaurants and concert halls. Comparing belief in the effectiveness of masks with the myth of the Loch Ness monster, the author argues that no experimental scientific proof exists that surgical masks can replace social distancing, distinguishes such proof from statistical evidence, and contends that masks worn by the general public are seldom sterile or well fitting. Using simple experiments with water in a mask and published data on air speeds when speaking, coughing and sneezing, the article argues that pressure surges from coughing or sneezing drive moist air through the mask and that most breath passes through the openings along its edges. Drawing on the physical-chemical behaviour of water and aerosols, it relates the persistence of exhaled aerosols to temperature and relative humidity, reports measurements made in marl quarries and tests with CO2 meters, and argues that CO2 measurements are useless for preventing Corona infections. The author concludes that keeping distance and ventilating rooms well, without letting them cool down too much, are what matters, that masks offer only a false feeling of safety, and that long-term mask wearing may cause side effects.
