There are bright ages and there are dark ages. Although the cycle of life is made up of the alternation of sunlight, in some periods it seems that the sun never rises. And when there are wars in between, it is always in the dark and freedom seems so suppressed that not even the sun gives that hope .. what is freedom? It is being able to do what I want while respecting the freedom of the other. But if my concept of freedom is different, the system of society becomes utopian. The 3rd millennium is characterized by having exported democracy to exasperation leading it almost to a democratic dictatorship. Paradoxically, although China has nothing to do with most of the wars that have taken place in recent years, it nevertheless identifies the concept of democratic dictatorship at its perfection.
Today Google Doodle celebrates the 138th birthday of Polish inventor, physician and immunologist Rudolf Weigl. He is known as the creator of the first effective vaccine against it 7; typhus epidemic. There are three types of typhus: exfoliating typhus, mouse typhus, and epidemic typhus. It is a group of diseases caused by bacteria that spread fleas, lice and fleas.
Each insect spreads a type of typhus: chicks spread typhus patchy, fleas spread mouse typhus, and body lice spread epidemic typhus. According to the US CDC, epidemic typhus was the cause of death for millions of people in previous centuries, but today it is very rare. When cases occur, it is observed in areas of extreme overcrowding, where body lice can easily pass from one person to another. Born in 1883, Weigl was born in what is now the Czech Republic as the son of Austro-German parents. His father died in a bicycle accident and his mother remarried a Polish high school teacher.
In 1907 he completed his studies in biology at the Polish University of Lwów and then obtained a doctorate in zoology, comparative anatomy and histology. Typhus was a big problem during World War I, and Weigl has been studying lice in his lab for decades and has been able to develop a vaccine from these small insects. After Charles Nicolle’s preliminary work in 1909 (he discovered that lice were the vector of epidemic typhus), Weigl began work on a vaccine against epidemic typhus. To develop the vaccine, he bred the lice that Rickettsia prowazeki had been infected with and then crushed into a vaccine paste. He used this paste for experiments on animals and also performed some experiments on humans.
Weigl was successful in 1936 and vaccinated its first beneficiary. During the Soviet occupation he headed the Department of General Biology at Lviv University and worked on the development of this vaccine. The Typhus Research Institute was founded in his department. It maintained its position during the occupation as its research was particularly important as typhus spread mainly in Eastern Europe

The donkey (mule) is often present in the common imagination for pumping water from a well. So this animal represents the water cycle and thus the life cycle. But sometimes man manages to corrupt even animals to generate a cycle of death ..
What is freedom?It is also being able to dream, free from any belief. But also the history of man is a religion to which we must wriggle out and think for ourselves, without inculcating any idea but making people reflect and bringing it to the truth closest to them.
Because our dreams are often stolen, and with them our freedom too
