...The latter is described simply as nothing, or the negation of body.” In turn, Democritus’s proposal lead to John Dalton’s conception of what we know today as the Atomic Theory. Which, according to Boundless Chemistry, was the first credited modern theory. As stated, “the English chemist and meteorologist John Dalton is credited with the first modern atomic theory, as explained in his A New System of Chemical Philosophy. Dalton’s experiments with gases led to some of the earliest measurements of atomic masses and a concept of atomic structure and reactivity. Dalton’s atomic theory contained the following ideas: All atoms of a given element are identical. The atoms of different elements vary in mass and size. Atoms are indestructible. Chemical reactions may result in their rearrangement, but not their creation or destruction. Dalton also outlined a law of multiple proportions, which described how reactants will combine in set ratios. Like the early philosophers, Dalton’s theories were not popularly accepted for much of the 19th century, but his ideas have since been accepted, with amendments addressing subatomic particles and the interconversion of energy and mass.” An...

...ATOM Marvin Jake Acle: The atom is a basic unit of matter that consists of a dense central nucleus surrounded by a cloud of negatively charged electrons. Chemical atoms, which in science now carry the simple name of "atom," are minuscule objects with diameters of a few tenths of ananometer and tiny masses proportional to the volume implied by these dimensions. Atoms can only be observed individually using special instruments such as the scanning tunneling microscope. Greek Atom The name atom comes from the Greek ἄτομος (atomos, "indivisible") from ἀ- (a-, "not") and τέμνω (temnō, "I cut"),[3] which means uncuttable, or indivisible, something that cannot be divided further.[4] The concept of an atom as an indivisible component of matter was first proposed by early Indian and Greek philosophers. In the 18th and 19th centuries, chemists provided a physical basis for this idea by showing that certain substances could not be further broken down by chemical methods, and they applied the ancient philosophical name of atom to the chemical entity. During the late 19th and early 20th centuries, physicists discovered subatomic components and structure inside the atom, thereby demonstrating that the chemical "atom" was divisible and that the name might not be appropriate.[5][6] However, it was retained. This has led to some debate about whether the ancient philosophers, who intended to refer to fundamental individual objects with their concept of "atoms," were referring to modern...

...The traditional TOK diagram indicates four ways of knowing. Propose the inclusion of a fifth way of knowing selected from intuition, memory or imagination, and explore the knowledge issues it may raise in two areas of knowledge. The study of Theory of Knowledge (TOK) indicates four distinct ways of knowing: sense perception, emotion, reason and language; however, in this essay I will argue for the inclusion of intuition as a fifth way of knowing. Intuition is that moment of enlightenment that is unexpected in which something is revealed to give one a greater understanding on a problem or puzzle or issue of concern that is perplexing. A knowledge issue worth examining in relation to the role intuition plays in these areas of knowledge is: How does intuition lead to knowledge acquisition in the natural sciences and in ethics? Personal intuitive insight has to be in some form of communication which conforms to requirements of public knowledge, natural sciences conforming ...

...Development in the Study of Atomic Structure Bohr’s and Rutherford’s Contributions Mihret Gelan 17th September 2014 Word Count (title page & references excluded): 1459 Atomic Theory & Structure "By convention sweet, by convention bitter, by convention hot, by convention cold, by convention color: but in reality atoms and void." Those are the words of Democritus, one of the founding fathers of the ancient atomic theory, on his philosophical viewpoint on the nature of matter. It began as a philosophical concept in ancient Greece and India, but today, the atomic theory is not mere philosophy, but a scientific concept or model of the fundamental nature of matter. How it went from a philosophical belief called atomism to an empirically-proven, well-studied, scientific concept is what I’m going to explain throughout this essay; focusing on two renowned scientists of the early 20th century, Ernest Rutherford and Niels Bohr, who made significant contributions to this growing theory of the atom and its structure (the composition of the atom). The Atom before Bohr and Rutherford The modern model of the atom was built upon the many vital discoveries of the major scientists throughout history since the birth of the theory in ancient Greece. Bohr and Rutherford were able to make the discoveries and scientific conclusions they made because they were “standing on the shoulders of giants.” To begin with, Democritus, although not entirely correct, laid a philosophical foundation...

...Introduction to Chemistry I (MAE1106) Chapter 1: Properties, Measurement and Units Matter: All things we can see, or touch, whether books, pencils, telephones, or people as they have some thing in common. They are all composed of matter which is defined as anything that takes up space and has mass. Matter is generally considered to be a substance (often a particle) that has rest mass and (usually) also volume. Mass and weight are not really the same. The mass of a body is a measure of its resistance to a change in its velocity. Weight refers to the force with which an object of a certain mass is attracted by gravity to the earth or other body that may be near such as moon. The volume is determined by the three-dimensional space it occupies, while the mass is defined by the usual ways that mass is measured. Matter is also a general term for the substance of which all observable physical objects consist Properties of Substances Physical (Properties and Changes) A physical property is one that is displayed without any change in composition. (Intensive or Extensive) 1. Intensive: A physical property that will be the same regardless of the amount of matter. density: m/v • color: The pigment or shade • conductivity: electricity to flow through the substance • malleability: if a substance can be flattened • luster: how shiny the substance looks 2. Extensive: A physical property that will change if the amount of matter changes. • mass: how much...

...RICHARD DAWKINS-The Selfish Gene. Ebook v1.0. 'Who should read this book? Everyone interested in the universe and their place in it.' Jeffrey R. Baylis, Animal Behaviour Our genes made us. We animals exist for their preservation and are nothing more than their throwaway survival machines. The world of the selfish gene is one of savage competition, ruthless exploitation, and deceit. But what of the acts of apparent altruism found in nature-the bees who commit suicide when they sting to protect the hive, or the birds who risk their lives to warn the flock of an approaching hawk? Do they contravene the fundamental law of gene selfishness? By no means: Dawkins shows that the selfish gene is also the subtle gene. And he holds out the hope that our species-alone on earth-has the power to rebel against the designs of the selfish gene. This book is a call to arms. It is both manual and manifesto, and it grips like a thriller. The Selfish Gene, Richard Dawkins's brilliant first book and still his most famous, is an international bestseller in thirteen languages. For this new edition there are two major new chapters. 'learned, witty, and very well written...exhilaratingly good.' Sir Peter Medawar, Spectator Richard Dawkins is a Lecturer in Zoology at Oxford University and a Fellow of Mew College, and the author of The Blind Watchmaker. Preface to 1976 edition This book should be read almost as though it were science fiction. It is designed to appeal to the imagination. But it is not science...
