Experiment 2: IDENTIFICATION OF UNKNOWNS BY TLC AND MP IN COMBINATION Introduction: Thin layer chromatography (TLC) is one of the most valuable techniques in organic chemistry. This is a best method of separating and identifying mixtures of two or more compounds. The separation is accomplished by the distribution of the mixture between two phases: one that is stationary and one that is moving or mobile. Chromatography works on the principle that different compounds will have different

In Galileo’s letter to Castelli‚ Galileo explores the validity of the many interpretations of the Holy Scripture. Galileo states that if the “Holy Scripture can never lie or err and that its declarations are absolutely and inviolably true‚” but its interpretations are not always true. He also states that taking the text literally would create not only “contradictions‚ but also serious heresies and blasphemies”. Galileo explains since Scripture is a dictation of the Holy Spirit has to be dictated

Lab Report - Microbes Aim: To investigate four areas of the school and to find out which of the four have the most microbes. Areas to Sample: 1. Girl’s locker room (Senior school) 2. Girl’s locker room (Elementary school) 3. Boy’s locker room (Senior school) 4. Boy’s locker room (Elementary school) Hypothesis: We predict that the boy’s locker room in the senior school will have the most microbes. First of all‚ there are more people using our locker rooms in the Senior School

The Life of Galileo Bertolt Brecht Foreword Two SCENES‚ numbered 5 and 10 in the original version‚ are omitted from this edition of The Life of Galileo to reduce it to manageable length for students. A reader can follow the theme of the play clearly enough without them; on the other hand‚ what they contribute to its background‚ in the panic-stricken atmosphere of the plague and the wild hilarity of the carnival‚ needs stage presentation‚ even more than most of the other scenes‚ for its full effect

Galileo Galilei’s backlash from the Church To what extent did The Church restrict publishment of Galileo Galilei’s scientific findings? During the 1600s‚ the Church in Europe was tremendously influential in every aspect of society‚ but most important it was authoritative in the newly-developing scientific world. Specifically it controlled the scientific findings of one of the greatest scientists at the time‚ Galileo Galilei. With pressure from the clergy to

for years in order for it to bc considered a true work of art. Scientific theories are no different. As scientists discover more about how the earth‚ humans‚ animals‚ and celestial objects interact‚ theories arise and contradict to prior beliefs. Galileo bumped heads with the Church when he proposed and supported the notion that the earth rotated around the sun. Doctors tried to reason with mothers that believed taking vaccines would give their children autism. Both of these instances have clear similarities

Galileo lived in a time of division and repression between religious and scientific theory‚ where most writings were incendiary and disincentivized unity. His letter to the Grand Duchess Christina worked against what most of his contemporaries were peddling. Galileo’s assertions of separation in the meanings of scientific and religious thought powerfully achieve his goal of reconciling the conflict between science and religion. He does this by using credible sources to discredit those who speak against

very popularized and well known. Galileo found his ideas harshly criticized by the Jesuits‚ specifically Father Lorini of Florence. He was brought before the Bishop of Lodi‚ of the Holy Office‚ in 1616. The Bishop condemned Galileo’s heliocentric beliefs as heretical‚ and Galileo was made to renounce his beliefs‚ and no longer discuss them in anyway. The trial took place at the palace of Lord Cardinal Bellarmine‚ in Rome‚ and Reverend Badino Nores‚ Agostino
