Scientific theory M1
According to the oxford dictionary ‘’2008’’ scientific theory is ‘’ a well-substantiated explanation of some aspect of the natural world that is acquired through the scientific method and repeatedly tested and confirmed through observation and experimentation’’. In this essay I will be looking at three different types of theories. I will be looking at theories that science is still addressing, theories that science cannot answer yet and theories that science will never answer. By looking at these I will be able to differentiate between the different theories and identify their differences, strengths and weaknesses.

The cancerous cells can invade and destroy surrounding healthy tissue, including organs. ‘’ For many years the struggle to find a cure for cancer has been increasing. Although we have made advances in our cancer treatments and tests to identify the illness there is still no definite cure. There are currently many scientists, labs and organisations spending endless time and money working hard to find a cure. Each days we become closer and have the reason to believe that a cure is in the foreseeable future. Therefore this is classed as a scientific theory that is currently being addressing, as we see that it is a problem that has the potential to be
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
Cancer is a disease in which cells multiply out of control and gradually build a mass of tissue called a tumor. There has been a large amount of research dedicated to the treatment and cure of cancer. Several types of treatments have been developed. The following are just some of the major examples of cancer therapy: surgery, chemotherapy, radiation therapy, biologic therapy, biorhythms, unconventional treatments, and hyperthermia. Each type of treatment is discussed in detail below.
Cancer has been an active concern in our society for the past couple decades, since we truly discovered the nature of cancer and the potency it brings along with it. However, it was not until the mid-20th century that scientists were beginning to truly understand the origin of cancer. Scientists dating back all the way to the Renaissance, when they first began performing autopsies to learn more about the human body and form, noticed abnormalities but it never clicked that it was something much worse than it seemed. Research has continued since then, and it has continued to thrive even to this day. When James Watson and Francis Crick discovered DNA and it’s chemical structure in 1962, it opened up doors that even they could not expect. With the understanding of DNA and how it affected the way we look at life, came the beginning of the understanding of mutated DNA (which is a cause of the growth of cancerous cells). In this past century, researching scientists discovered that cancer is linked with the DNA that resides in a cell’s nucleus. By ways of damage to the cells via chemicals or radiation, or even introduction of a new DNA, the cancerous cells begin to form and duplicate. We are learning more and more about cancer and how to fight it, but we still have much more to learn.
There are many definitions to theory. According to Akers (2009) “theories are tentative answers to the commonly asked questions about events and behavior” (Akers, (2009, p. 1). Theory is a set of interconnect statements that explain how two or more things are related in two casual fashions, based upon a confirmed hypotheses and established multiple times by disconnected groups of researchers.
Cancer starts when certain cells in the body are mutated or changed and begin to divide. Cancerous cells grow differently than normal cells, instead of progressing through the normal cell lifecycle, cancer cells continue to grow and create more abnormal cells. A specific trait of cancer cells is that they have the ability to infiltrate and grow into surrounding tissues, developing out of control and causing serious damage to the host (Vincent, 2008). Cells become cance...
”Theories tell how and why things work; how and why one variable is related to another. Research findings that are theory based can be place in a framework that advances science further than findings that are unconnected to formal theory.” (O'Connell, 2009, p. 33).
Science: the concerted human effort to understand, or to understand better, the history of the natural world and how the natural world works, with observable physical evidence as the basis of that understanding. Science is not just a word to be tossed around, it truly is a magnificent universe of different theories and studies all brought up by normal people. Through mankind’s entire finding we come across many theories, like the theory of plate tectonics or the heliocentric model theory. A theory is a group of ideas meant to explain a certain topic, such as a single or collection of fact, event, or phenomena. Technically a theory can never be proven, although many argue that most theories are entirely true, such as Evolution. But, evolution is a totally different subject when it comes to schooling.
... a theory should be able to explain a wide variety of things, not just only what it was intended to explain.
Any hypothesis, Gould says, begins with the collection of facts. In this early stage of a theory development bad science leads nowhere, since it contains either little or contradicting evidence. On the other hand, Gould suggests, testable proposals are accepted temporarily, furthermore, new collected facts confirm a hypothesis. That is how good science works. It is self-correcting and self-developing with the flow of time: new information improves a good theory and makes it more precise. Finally, good hypotheses create logical relations to other subjects and contribute to their expansion.

Cancer is a disease that affects human somatic cells. It causes the cells to divide uncontrollably and form masses known as tumors. There are two different types of cancer tumors. Some tumors are benign and other tumors are malignant. Benign tumors look similar to the tissues that they came from and develop slowly. The tumor remains in the same area that the tumor originated in. Malignant tumors are formed from cells that do not resemble the tissue that they came from. They vary in shape and size. This enables pieces of the tumor to break off and spread to other places in the body. Over the past few decades cancer has become a very prominent disease. There are many different types of cancer and many different causes for the the disease. Most cancers are because of a genetic mutation. The most common type occur when a cell is dividing. Proto-oncogenes, which are alleles in a normal cells, mutate to form oncogenes. These oncogenes cause cancer because they do not allow the cells to self destruct or become epistatic. There have been several research projects which have been testing epistatis.
Cancer is defined as where the abnormal cells are divided without any control and they are able to invade into tissues. At times cancer can be cured right away once it is detected through treatments that the doctor recommends, but at times cancer cannot be cured based on what stage the cancer is at. It is very important that every individual gets a physical check up to see if they are diagnosed or detected with any sort of cancer or disease. There are 100 types of cancers out there, but the type of cancer that I will be focusing on is Lung cancer. One of the controversial issues on a lung cancer is the ...
What is Science Essay Incomplete The word "science" means "knowledge." The baseline definition of "science," then, is human knowledge. Empirical thought is founded on the idea that all knowledge of the world comes from sensory experience; this sensory experience can be trusted to give us an accurate picture of the world. From sensory experience, we can derive the principles whereby the world works by observing phenomena repeatedly and in controlled circumstances.
A scientific theory is an explanation that is well- substantiated explanation in regards to some aspect of the natural world that is attained through scientific method and is tested numerous times and usually confirmed through vigorous observation and experimentation. The term theory can be seen as a collection of laws which allow you to show some kind of phenomenon. The strength of a scientific theory associated with the diversity of phenomena can explain its elegance and simplicity. However when new evidence is gathered a scientific theory can be changed or even rejected if it does not fit the new findings, in such cases a more accurate theory is formed. Scientific theories are used to gain further
The word theory emanated from the Greek word meaning “contemplate” It has been viewed by scholars in different ways. Theory can be defined literally as an explanation of phenomena and its associations with variables that it is attempting to predict. There are no general agreed definitions of theory because scholar’s views of what constitute theory differ based on the purpose, nature and what make up of a good theory (Gelso, 2006; Harlow, 2009; Stam, 2007, 2010; and Wacker 1998). For instance, Wacker, (1998), pointed out that a theory must have four basic criteria such as conceptual definitions, domain limitations, relationship-building, and predictions. He, also, opined that for any theory to be regarded as a good theory, it must have qualities for `good ' theory, such as “uniqueness, parsimony, conservation, generalizability, fecundity, internal consistency, empirical riskiness, and abstraction, which apply to all research methods” (p.364). Stam (2010) interpreted theory as ...
