To begin, theories change in different ways. For example, theories change if facts are found to be incorrect, maybe something was not thought out enough, and if any of the trials fail. In 460-370 B.C some scientists were to believe that atoms were completely solid because atoms were so small they couldn’t split. In 500 B.C Leucippus and Democritus proposed that all matter is composed of tiny particles called atoms that can't be split into smaller pieces. In 1821 Michael Faraday discovered electricity by carrying a wire with an electric current to a magnetic pole and then the wire rotated. Also, in 1930-2006 scientists decided that Pluto was not a planet but was a dwarf planet and the reason why Pluto is no longer a planet is because astronomers
In 1803 this theory was finalised and stated that (1) all matter is made up of the smallest possible particles termed atoms, (2) atoms of a given element have unique characteristics and weight, and (3) three types of atoms exist: simple (elements), compound (simple molecules), and complex (complex molecules).
In science, a theory will refer to an explanation of an important feature of the world supported by testing and facts that have been gathered over time. It’s there scientific theories that allow scientists to make predictions about untested and unobserved concurrences in the world. The American Association for the Advancement of Science has this explanation of what a theory means to those in the science field, and it is as follows, “A scientific theory is a well substantiated explanation of some aspect of the natural world, based on a body of facts......Such fact supported theories are not guesses but reliable accounts of the real
First, when observations are made, hypothesises are formed. To test these hypothesises scientists conduct experiments. If their hypothesis is right, it is confirmed by further experiments and validated by other scientists. After many experiments and confirmations, a theory is formed. A scientific theory is a broad and general idea or explanation provided by scientists and is related to observations and is supported by a large amount of evidence. A theory is not a fact however it is just a possible explanation. An example of a theory is the Big Bang Theory.
Pluto: A Planet of the Earth? Many issues have arisen from the debate over whether or not Pluto is a planet. Some astronomers say that Pluto should be classified as a “minor planet” due to its size, physical characteristics, and other factors. On the other hand, some astronomers defend Pluto’s planet status, citing several key features. Indeed, most of the problem is that there is no formal definition of a planet.
2,870,990,000 km (19.218 AU) from the Sun, Uranus hangs on the wall of space as a mysterious blue green planet. With a mass of 8.683e25 kg and a diameter of 51,118 km at the equator, Uranus is the third largest planet in our solar system. It has been described as a planet that was slugged a few billion years ago by a large onrushing object, knocked down (never to get up), and now proceeds to roll around an 84-year orbit on its belly. As the strangest of the Jovian planets, the description is accurate. Uranus has a 17 hour and 14 minute day and takes 84 years to make its way about the sun with an axis tilted at around 90° with retrograde rotation. Stranger still is the fact that Uranus' axis is almost parallel to the ecliptic, hence the expression "on its belly".
...ned their idea and focused on a new change instead, the Copernican system. This was a good example of how scientists kept trying to study within their paradigm dimensions but instead of uncovering more normal science, anomalies were discovered breaking their old scientific tradition. As said earlier by Kuhn, as a new paradigm gains fame, the older paradigms lose members and their ideas and assumptions eventually get entirely forgotten. This is what Kuhn means by ‘mop-up work’ and how scientists strive to keep researching to expand upon the scientific achievements the community have deemed to be worthy or particularly revealing. New and unsuspected phenomena’s and anomalies are impossible to not uncover, introducing problems with the paradigm criterion and forcing scientists to possibly change their perspective on things, in time possibly resulting in a new paradigm.
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.
In the area of Natural Sciences, new advances in the field are proposed by theorized conclusions before the theory is ever tested or proved. So in order for the different fields to move past the accepted knowledge to become more
Thomas Kuhn, a philosopher of science, however, believes that this view of science is not accurate. He wrote an article titled: The Structure of Scientific Revolution that made an argument that science does not progress in a linear fashion in regards to knowledge, but rather science has two different forms of scientific knowledge accumulation. Paradigms are the “king” in the realm of scientific inquiry. These are wordily held theories that are at the forefront of science that everyone believes. When scientists encounter anomalies that cannot be explained by these universally accepted paradigms a new paradigm is brought into focus and “revolutionary science” occurs. These “paradigm shifts” abruptly transform that given scientific field and new theories start developing. This results in a rapid increase of knowledge for that given field. The Capricious revolution is a great example of this type of science. The prior paradigm in the scientific community was that the earth was flat, but then a revolution occurred and a new paradigm emerged – that the earth was in-fact, round.
Reality changes continuously. Current reality influences new technology, thinking and language in all aspects of life and in turn these things influence the current reality. For example, when scientists discovered the atom they thought they held the key to understanding what matter was made of and how the universe works. However, when scientists were able to see inside the atom they realized that it was made of even smaller particles which prompted the thought that there might even be something smaller inside those particles. The theories continue to grow and they will be altered as reality chan...
Our solar system has eight planets, their moons and satellites, and they are all orbiting the Sun. The eight planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Pluto used to be the ninth planet but IAU changed the definition of planet and Pluto did not meet the standards so it is now a Dwarf planet.
Scientists prove theories by testing situations a series of times to determine if the results are typical and consistent over time. When a theory is found to be consistent it becomes a scientific law, for example, Newton’s Law of Physics. A scientific law is a proven truth. Descartes argues, “that all clear and distinct ideas are true,” (Flage, 2014), therefore, in science, clear and distinct ideas are truths according to Descartes. Further to this he states, “clear and distinct idea is materially true if and only if it is consistent and therefore capable of representing an actual object,” (Flage, 2014). Street an...
However, because of the fact that knowledge is constantly evolving and changing, knowledge that was once considered to be fact is disproven creating a scenario where the theories that we accept today are waiting to be proven wrong in the future due to advances in areas such as technology. This is demonstrated by the changing in understanding surrounding the atom. Ideas have constantly changed surrounding the shape of the atom. This can be seen by John Dalton who in 1803, built upon previous interpretations concerning Proust’s Law by determining the Law of multiple proportions . This would have made previous scientists using the older model question what they knew was actually true and that their theories had been proven wrong and so should be discarded. From this stems an issue whereby there are factors hindering you to accept new knowledge, one may believe that we can have solid facts but by time progressing, perspectives change and with that facts can become reinterpreted due to ...
First and foremost, several researches’ that had been done in the past and taken to be the gospel truth for many years have been disapproved by new research that has been conducted in the recent past. Research is a process that never ends (Griffiths, 1998, p97). It is a continuous process that evolves in a way that a person uses conclusions to explain some concepts while another researcher uses the same conclusions to conclude a new concept. A Good example has been the case of Pluto. Since its discovery in 1930 by Tombaugh, Pluto had been considered as the smallest planet in the solar system. This was until august 2006 when International A...
