An expert on my field

An expert very famous is Paracelsus and for me one of my favorites. Well, his full name is Philippus Aureolus Theophratus Bombastus von Hohenheim, but he's know by Paracelsus, born Theophratus von Hohenheim, was a Swiss physician, alchemist and astrologer of the German Renaissance. He was a pioneer in several aspects of the "medical revolution"of the Renaissance, he is credited as the "father of toxicology".

Paracelsus was one of the first medical professors to recognise that physicians required a solid academic knowledge in the natural sciences, especially chemistry. Paracelsus pioneered the use of chemicals and minerals in medicine. Paracelsus theorised that materials which are poisonous in large doses may be curative in small doses; he demonstrated this with the examples of magnetism and static electricity, wherein a small magnet can attract much larger metals. He clearly expounded the concept of dose response in his Third Defence, where he stated that "Solely the dose determines that a thing is not a poison." (Sola dosis facit venenum "Only the dose makes the poison").

I like Paracelsus, because the had a thought different to the rest of the people at that time (I'm talking about the years 1500-1600), that makes it out od the ordinary and I've always been attracted to people like that. I have always liked the branch of toxicology, I find that it is an interesting branch, talking about the chemical and medical part. Paracelsus is one of the pioneers of this branch and that's a good reason why he's one of my favorite experts. One of his most striking phrases for me is "Solely the dose determines that a thing is not a poison.", this phrase fits even for our daily life.
