Ch 3 Outline: Pg. 61 Once upon a time a Chinese cook combined charcoal with two other common Chinese ingredients. It ended with an explosion of sparks. Even if that story is false, most everyone agrees that fireworks originated from China.
The Atomic Theory began in roughly 400BC with Democritus in Ancient Greece and is universally believed to be correct today. Democritus who was born in 460 BC and died 370 BC and is known as the father of modern science. Democritus proclaimed that everything is made up of atoms. He continued his theory to say that atoms will always be in motion, between atoms there is empty space, atoms are unbreakable, there are an infinite number of atoms all different sizes and shapes. He also said that iron atoms are solid and strong and have hooks to lock them together, water atoms are smooth and slippery, salt atoms have sharp jagged edges because of its taste and air atoms are light and spiralling.
Dalton’s atomic theory, which stated “the atoms were tiny, indivisible, indestructible particles” (Bender), differed drastically from that of the Greeks’ in that it “wasn’t just a philosophical statement that there are atoms because there must be atoms” (Bender). Although Aristotle believed that there are four terrestrial elements, earth, water, air, and fire, Democratus believed that “a piece of a substance can be divided into smaller pieces of that substance until we get down to a fundamental level at which you can’t divide the substance up and still have pieces of that substance” (“Atoms”). Aristotle’s theory was popular, but incorrect; Democratus’s was closer to our current theory, yet he remained relatively unpopular and obscure. This demonstrates of the key way in which a personal point of view can, in fact, retard the pursuit of knowledge. The scientist with the better oratory abilities has his theories more widely accepted. Dalton’s own theory, which extrapolated upon four basic
Atomic science began many centuries ago with ancient philosophers and alchemists experimenting and probing into the nature and structure of matter. Science began emerging when Thales of Miletus, the Ioian Greek in (634-546 BC) described the power of attraction in electricity long before electricity was known. In (460-370 BC) a Greek philosopher named Demoncritus was called the “father of the atom”. Although he had no experimental evidence to support himself, Demoncritus argued that all matter must consist of a number of fundamental pieces. He called these pieces “atoms” from the Greek word “atomon” which means indivisible. In (79 BC), the Roman poet-philosopher Titus Lucretius developed atomic theory. After the fall of the Roman Empire and
Atomism originated in the school of Leucippus, which was located in Abdera, Thrace, by none other than Leucippus himself. However, the biggest flag bearer for this particular philosophy was Democritus, a student who was taught directly by Leucippus, who worked closely with Leucippus on the theories behind atomism. Democritus took the workings of his teacher and popularizing them, taking the ideas of atomism and put them into the philosophical sphere to be picked over by other great minds such as Plato and his followers,, and many others throughout the ages. The two basic ideas of atomism are the atom, a word which comes from the Greek word “atomos” meaning uncuttable. All atoms are uniform in size and form with no fluctuating properties. The second tenant of atomism is known as the void which, as the name suggests, is the lack of any matter and is the emptiness that atoms interact within. These two ideas are the foundations for atomistic ideas that were then expanded upon with each philosopher adding there own take on how atoms interacted with each other and with macroscopic beings. Through out its existence atomism led to much more than a debate on the composition of the universe. Atomism also led to discussions on how people and the universe interact on a daily basis and how that interaction affected a person’s life by showing the role of the atom in everything from taste of our food to the color of our shirt these were all explained with atoms. Atomism was even woven into debates such as the reality of reality and the legitimacy of knowledge.
Some of humans’ knowledge comes from the complex theories established in the field of natural sciences. As scientists, we set the bases for an experiment and we let other people set up theories to explore beyond the known. Then, we look at the theories and we choose the one that best describes the concept and tells us the most facts. When I was taking my first year of IB physics, one of the topics was Atomic and Nuclear physics. The topic was mainly about nuclear structure, radioactive decay, nuclear reactions and so on, but there was something in that topic that drew my attention, the model of the Atom. Ever since the fifth century, the understanding of the atom has evolved. The Greeks invented the idea of the atom, and they believed that it wasn’t physically divisible. Then, ...
The Periodic table of elements is an extremely important and useful scientific tool, mostly in the area of chemistry, but also in many other scientific areas. It has been around for hundreds of years and over time has been continuously added to and develop by many different scientists. The Periodic table contains over 100 elements, each one with varying physical and chemical properties. The Periodic table has not been simply one person creating and discovering all the elements, it has been the combined work of many different scientists. Although, Dimitri Mendeleev is often considered the creator or even father of the Periodic system.
The understanding that matter was composed of atoms was changed with the discovery of smaller particles than the atoms, which are protons, neutrons, and electrons. But during the 1960’s, the multitude of particles being discovered was making the understanding that matter is composed of protons, neutrons, and electrons, insufficient. Murray Ge...
...ir general outlook seems quite appealing after consideration but in relation to common sense, it may be difficult to imagine. Even though through advances in science we now know those atoms are not basic; the claim that everything was different compounds of minute particles too small for human eyes to see is still genius. Although Democritus’ based his principles of atoms off Empedocles’ basic elements theory, we do not know why the philosopher decided the answer was tiny particles. The philosophical and mathematical reasoning’s behind his answer is not clear. It seems that Zeno’s fight against plurality may have helped lead the Atomist toward their conclusion of plurality.
