1. THE DYING SUN Q. 1: How is it that star seldom finds another star near it? Ans: A star seldom finds another star near it because there is a distance of millions of miles between the two stars. Moreover‚ space is immensely vast and each star is bound to travel in its own orbit. Q. 2: What happened when‚ according to Sir James Jeans‚ a wandering star‚ wandering through space came near the sun? Ans: When a wandering star came near the sun‚ it raised tides on the surface of the sun

knew of their existence1. Joseph Lister‚ a British surgeon experimented with the sanitation of surgical instruments before procedures. He understood the outcomes of his procedures‚ just not why antiseptics worked. Lister was following the work of Louis Pasteur‚ and understood he needed to kill whatever was causing the patients to die after surgery2. Before Germs Before the theory of germs there were several explanations for disease‚ the first being Miasmas. It was understood the air carried disease

Microbacteria are rod shaped Desmobacteria are filamentous Spirobacteria are spiral shaped 1822-1895 Louis Pasteur Defined pasteurization to prevent spoilage of food by bacteria‚ develop vaccines and disproved the scientific dogma of “Spontaneous Generation”. He defined “Germ Theory” and demonstrated that germs were responsible for disease. 1843-1910

Joseph Lister was more significant in the fight against infection in surgery than Ignaz Semmelweiss? Discuss. Joseph Lister was one of the outstanding surgeons of the nineteenth century. He had research gangrene and infections and had a keen interest in the application of science to medicine. By using Pasteur’s germ theory‚ experimented with carbolic spray acid‚ which was used to treat sewage. Joseph Lister is one of the pioneers of Infection Control. Not only did he reduce the incidence of

Hi Robert‚ I enjoyed your information on Luis Pasteur. He was most definitely an amazing microbiologist. I must agree with you that his contributions to science and the world are without question remarkable and through your presentation of this scientist‚ I was reminded of studying him in my 10th grade biology class many many years ago. In addition to all the contributions you mentioned‚ I believe Luis Pasteur could also be considered the founder of medical microbiology who broke the germ

throughout the 1800’s. Many things that are being used in hospitals today were developed in this time period‚ such as anesthesia‚ x-rays‚ and many other things. The Germ Theory was an important discovery for the medical field in the 19th century. Louis Pasteur proved that the souring of milk was caused by living organisms. He would boil liquids known to ferment in a “swan necked flask” and let them cool‚ he found that none of them went through fermentation after being boiled. This confirmed the theory

French beverage industry was thriving. Pasteur was called upon to tackle some of the problems that were plaguing the industry. The special concern was the spoiling of wine and beer‚ which caused great economic loss and tarnished France’s reputation for fine vintage wines. He noticed that when aged properly‚ the liquid contained little yeast cells. But when the wine turned sour‚ he was a proliferation of bacterial cells which were producing lactic acid. Pasteur suggested that heating the wine gently
