It is believed that he was the scientist to create the first atomic theory (Coffey, 2010). He claimed that absolutely everything is made up from atoms and that the atom is was the smallest particle of matter (Bennett, 2012). He also stated that atoms are physically indivisible and indestructible they have been and always will be, there

The Weaknesses and Strengths of Common Sense and Science as Sources of Knowledge There are many sources of knowledge as the society progresses. In this case, the most controversial question would be whether or not common sense can be accounted as a reliable source of knowledge? Although both common sense and science can be taken into account as sources of knowledge, I will argue that to some extent common sense and scientific knowledge are still very different from one another. That is, scientific

usually follows Zaitsev’s rule wherein it yields the more stable alkene as the major product. The reaction is an E1 process and occurs by the three step mechanisms. Unimolecular loss of water to generate a carbocation intermediate and final loss of proton from the neighboring carbon atom happens after the protonation of the alcohol oxygen to complete the process. Tertiary alcohols usually react fastest in an E1 reaction because they lead to stabilized tertiary carbocation intermediates. Secondary alcohols
