Describe the impact pasteur's work had on the scientific community

Louis Pasteur was a renowned chemist, inventor, and scientist, whose name lends itself to the word "pasteurization", the process for which he is widely recognized for, being the invention of the treatment of wine and milk to prevent contamination from bacteria. He is widely acknowledged for his research in medicine and vaccinations, he is today considered one of the fathers of germ theory. 

Hamlet's fourth soliloquy is probably his most famous one - "to be or not to be."it is rather different from his previous soliloquies because now he is contemplating something that didn't come up before - suicide. he is thinking whether it is worth it to fight to find his father's murderer when in the end all of them are going to die, so why not die sooner than later. he is contemplating if he should go on fighting or just kill himself and end it all, which is why this soliloquy in particular is rather depressing, hesitant, and gives a deeper insight into hamlet's madness.
