The results of the poll are very much my experience.

In your book, write a few comments like "I think therefore I am" and also become famous as the father of modern philosophy too.

Leonardo da Vinci (1452 to 1519), was ahead of his time in his investigations of the concept of gravity. His research was first discovered in the Codex Arundel, a compilation of da Vinci's writings on topics that included science, art, and personal experiences. In his notes, da Vinci detailed an experiment in which a water jug was moved parallel to the ground, releasing either water or sand. He observed that the sand or water would accelerate and fall at an entirely downward acceleration due to gravity. Additionally, da Vinci observed that the horizontal acceleration of the material stopped, implying that there was no more external force being applied to it. Unfortunately he used an incorrect equation, still, his insights into the concept of gravity were significantly ahead of his time. The paper is here but unfortunately protected by a paywall. https://direct.mit.edu/leon/article-abstract/doi/10.1162/leon_a_02322/113863/Leonardo-da-Vinci-s-Visualization-of-Gravity-as-a?redirectedFrom=fulltext

In relations with Turkey and Russia, Russia now gives money.

Without statistics, a germ theory, and no microscope, it's not an easy sell

This might explain why Poland was relatively unaffected as the poles tended to use their own clothings

No one accepted his findings. He went crazy

Yes but rats are the carriers

Why would they believe that what you are asking them would make any difference?

What happened is that rats get infected by fleas. The fleas like the rats so they live in harmony. However if the rat population goes down, the fleas look for another host - a person, so the plague explodes.

People can spread it too

My pet theory is that birds might carry it too

What are you disagreeing with me?

The flea is the vector but the primary mover is rats.

Ships yes but carts no, rats do not like travelling on carts.

The problem is that the Black Death's expansion was faster than the rats' travel. If you look at the plague in India in the late 1800s, it spread much slower.

This is indeed the commonly accepted view

Not sure unlike plague. Smallpox was always there so it would be interesting to see a study of the America's after the Spanish came.maybe someone here can help us out?

What is commonly believed is that the fleas stuck to the rats until the rats' population went down, and then the fleas switched to people.

Black Death travelled much faster than any spread of Yersinia pestis we know about not only that it spread much wider.

Trade, not migration, whether it's the vector, is debated

This is what most believe.

Black death is different than other plagues in that it spread very rapidly as such some like me think it needs a different vector than rats.

Everyone was involved in the slave trade, blacks, whites, Muslims, pagans, christains, male and females.

The article raises the question of whether the bubonic form of the plague relied on slow-moving rodents for transmission or if it could spread more efficiently through direct human contact through ectoparasites or respiratory and touch transmission.

Another possibility is birds
