We used to have scientists have a further vision, as their imagination accepts everything that contradicts logic and habitual until it becomes true, but this may not be much achieved, as some historical figures have erred in assessing matters, and perhaps these mistakes are forgotten, but history is not forgotten.

In her report, published by the Russian "FBR" website, the writer Christina Degareva reviewed unexpected errors of some historical figures, most notably the following:

Dionysius Landner and the railroad
Dionysius Lardner, a mathematician and Irish professor who worked in the nineteenth century, wrote many mathematical works, but the "encyclopedia" remains his most important achievement, as it contains more than 133 volumes and covers various topics such as science and history. The encyclopedia included the work of many researchers of the time, such as John Herschel, Mary Shelley, Walter Scott and Thomas More.

In spite of his successes, Lordner failed to meet many scientific expectations, such as saying that the use of steam boats to cross the Atlantic is impossible, just like going up to the moon. Moreover, his stance on train travel is his biggest mistake, as he acknowledged that anyone traveling at full speed on trains would suffocate due to a lack of oxygen.

Mermaids
The writer said that the explorer Christopher Columbus, while sailing near the Dominican Republic, imagined that he had seen three mermaids, but after that, according to the drawings, it turned out that these creatures are nothing but sea lambs that quickly descended to inhale the air, and deceived the sailors.

Nebraska man
The author states that Henry Farfield Osborne is considered an important name in paleontology, having served as President of the American Museum of Natural History for 25 years in a row. However, Osborne did not manage to avoid some mistakes that may have negatively affected his scientific career.

In this context, the Nebraska Man was the black spot that stained the researcher's career, as Osborne announced the existence of the Nebraska Man based on the molar found by ranchers and geologist Harold Cook in Nebraska in 1917, and Osborne obtained it in 1922.

As a result of research on Harold Cook's farm, more bones belonging to that species have been found, which are in fact due to an extinct species of peccary, an animal similar to the domestic pig.

Yogan Stefler and the End of the World
Yogan Stevler is a mathematician and astronomer, whose research has emerged in the sixteenth century, he wrote a book talking about how to build and use astrolabe (a device used to monitor planets and determine the heights of celestial bodies, time and trends in the past).

In 1499, Stefler stated that a gigantic flood would swallow the whole world after 25 years, and given his previous credibility, he published about a hundred brochures across Europe on this topic, and warned everyone against impending doom.

Goebbels and the Jewish girl
Thanks to the initial success of the Nazis, Joseph Goebbels - responsible for political propaganda during the time of the Nazi leader Adolf Hitler - devoted all his efforts to portraying the Jewish people as responsible for all the evils that occur in the world. It is worth noting that in 1934, and long before World War II, Goebbels had already spread hate and searched for the perfect child to campaign.

To this end, Goebbels organized a competition to find the most beautiful Arian child. As a result, a child of no more than two months was chosen, and her face was used in all types of Nazi propaganda. In fact, Goebbels did not realize that the child bears the name of Hessie Levinsons Taft and is from a Jewish family.

William Henry Price and telephone
The writer added that William Henry Price is an inventor and engineer, and worked on the first national communications systems in the United Kingdom, using telegraph technology, and also served as President of the Institute of Civil Engineers and the Institute of Electrical Engineers.

Despite the success of Price in this area, he questioned the invention of the phone, and underestimated its benefits, but after that he realized his mistake and became a supporter of the phones.
