The strangest beliefs believed by scientists in the past!

    With great scientific progress, the truth of most of the mysteries surrounding us has become evident and our view of the world has become clearer than before. But every beginning must be difficult. In previous centuries, scientists believed in strange theories and were based on the interpretation of things on beliefs that seem silly and ridiculous now!

    In this article, we review some of the strangest beliefs on which scientists have based their interpretation of theories that seem so crazy today!

    The strangest beliefs believed by scientists in the past!

    "Myasma" theory of disease spread

    Before the advent of germ theory of disease, doctors believed that diseases spread according to a theory they called "Myasma", which means that diseases spread through the high toxic air of the Earth as a result of decomposition of organic matter and carried by the wind from stagnant marshes and cemeteries.

    Intercontinental Bridges

    Before accepting the theory of tectonic plates, scientists believed that there are large "intercontinental" bridges, stretching thousands of miles deep in the ocean, which bind continents to each other.

    Disinfect the hands of doctors before dealing with patients

    Before the 1860s, doctors did not wash their hands before dealing with patients. The doctor who advises this act is described as suffering from a nervous breakdown!

    Use mercury as a treatment

    In the past, the dangers of toxic mercury were not known, and were described as a disinfectant for wounds, laxative for intestines, treatment for syphilis, and even treatment of skin problems and acne!

    Travel speeds up to 30 mph

    In the past, there was a belief among people that traveling faster than 30 miles / hour would cause suffocation because they would not be able to breathe because of the surrounding air that was rushing to them. This belief prevailed before the invention of railways and the appearance of trains in the 1870s.


    Before the discovery of oxygen, scientists believed that fire and fire contained an important element called "phlogiston" that went into the atmosphere during fires. Use this element to understand combustion and rust operations. Phlogiston theory was the most accepted in science until the seventies of the seventeenth century, before Joseph Priestley discovered oxygen in 1774.


    Before the concept of vacuum appeared, physicists did not believe that there were empty spaces in the universe, and considered light traveling through an intermediary called the ether. The ether was considered to be a fifth element alongside Earth, wind, water and fire.

    The use of "benzene" as an aromatic and disinfectant

    In the 19th and early 20th centuries, gasoline was used as an aromatic liquid after shaving, and as an organic solvent, chemists used it to wash their hands despite being a carcinogen.

    The fact is the "taste points" in the tongue

    Even today, the concept of the "map of the tongue" is still very common and is taught in schools and universities that the tongue is divided into several regions, each of which feels different. But recent studies have shown that the tongue plan is wrong in form and content, and that all taste receptors in the tongue are able to sense different flavors, contrary to popular belief.
