Positive Aspects of Technology Essay Example for Free

Positive Aspects of Technology Essay From man`s first invention of the wheel to modern day’s advanced computers, one can clearly see how far humans have developed with technology. Modern technology has provided mankind with numerous positive aspects; from getting to places in seconds to curing complex diseases. The most fundamental and important positive aspect of technology is that it gives humans the ability to share knowledge more effectively. Nowadays, a country is not defined by its wealth or influence, rather by its â€Å"ability to develop and advance knowledge† (Johnston 1). In the essay, The Diplomacy of Knowledge, author David Johnston states that, â€Å"information has never been so ubiquitous and so cheaply and easily shared† (1). In other words, information has never been so readily available, thanks to the fast growing Internet. The Internet allows billions of people to express their opinions and put forth their knowledge for others to see. Johnston also mentions that the foundations of the internet were laid by â€Å"300 years of discovery in math and science from Newton to Einstein† (2). Great scientists such as Newton to Einstein shared their experience and findings which have become the cause of all the ongoing technological development. For instance, the recent uprising in Libya was hugely successful due to the internet. Thousands of people posted Facebook statuses and communicated in numerous other ways. By sharing each other’s thoughts and knowledge, they were able to overcome the situation by establishing a strong and organized community. Moreover, new inventions are also greatly impacted by the sharing of knowledge and this can be evidently seen with a great discovery such as Insulin. Charles Best and Frederick Banting, a bio-chemist and a surgeon, are innovators from different fields. Both of them shared each other’s knowledge and brought forth one of the greatest discoveries of all time, insulin which saved millions of diabetic patients. In other words, today’s advancements in technology let the sharing of knowledge much more effectively, as it allows mankind to â€Å"[experience] unprecedented rates of change† (2). It also gives humanity the opportunity to undergo â€Å"rapid transformations, characterized by risk and opportunity on a global scale â€Å"(2). These changes brought through the sharing of knowledge bring an evolution in social and ethical factors within the society. In conclusion, technology has provided mankind with countless positive aspects, although the greatest aspect is the better collaboration of knowledge. From insulin to modern medicine, history has made it clear that great things can happen when everyone shares their learning with each other. As Thomas Jefferson mentions, â€Å"[by lighting] your candle with the flame of mine, my light is not diminished, it is enhanced† (2).

The Yellow Wallpaper -- essays research papers

Yellow Wallpaper Without question the short story Yellow Wallpaper would definitely be categorized into a male dominant/feminist interpretation. The story is a perfect example of the stereotype, "that a male knows best". Throughout the story the author does a good job of placing you in the women's shoes. He makes you feel the control he has over her, mentally as well as physically. Most males have a tendency to think that they know best. A man will never stop at a gas station to ask directions from a local resident in a town that he has been lost in for two hours because of course he knows his way around far better than the local ever would. He will find his way eventually even if it takes him the entire day. John makes it well known that he knows best. In line 30 he states, "Your exercise depends on your strength, dear, and your food somewhat on your appetite; but air you can absorb all the time." Yes John is a physician but he does not know exactly what her illness is therefore; he cannot state what depends on what. He tells her that her exercise depends on her strength yet; she is not allowed to go out of the house. No matter her strength she will not be able exercise. The way the story is written (not organized/unfocused), gives you a claustrophobic feeling of no way out, just as the character feels. The story is written to make you empathize with the character. The form of writing is relat...

Does Source B support the evidence of source C about the suffragette campaign

In this essay I am going to be discussing whether or not source B which is an extract from a book written in 1907 called Woman or suffragette supports the evidence given from source C which is a cartoon drawn by Bernard Partridge in 1906 about the suffragette campaign and the writers and artists opinions on the suffragettes. Firstly I am going to point out that source B which is a primary source was written by a woman and it is against women getting the franchise to vote. The thing that is very ironic about this is that at the time it seemed all women wanted the vote and wouldn't stop at anything to get it but this one woman â€Å"Marie Corelli† didn't think that women should have the vote and that all women should just leave the men to all the important things. Source C is another primary source and it is contempory to source B. The reason why this is important is because it helps towards showing that all of the people sort of had the same ideas about women's suffrage. In source C it shows a sensible woman and what seems to be a lunatic woman. The lunatic woman was looked upon as the suffragette and she has one fist clenched and in the other hand she a flag which says female suffrage but it looks as if it is falling apart and wearing down as if they are destroying the whole purpose of campaigning for the right. Also the main reason why these sources could not be used in too much in depth study is because both sources are bias towards their own cause. Source C is obviously just trying to make the suffragettes look bad so that it makes the suffragists look better. Source B however seems to be bias towards the men and is trying to point out that women are naturally incapable of being as mature as the men. In conclusion I think than source B most definitely supports source C for one main reason. This is because they are both trying to get the point across that they don't think women are going to get the vote and the main reasons for this are the suffragettes. One reason though why I begin to think that these source may disagree with each other is because one of the sources (Source B) believes that women will never get the vote because of the way the women are raising their children. Whereas in Source C the main reason why this source thins women will not get the vote is because of the techniques used by the suffragettes for example the main quote used on the poster is â€Å"you help the cause? Why, you're its worst enemy!† this quote shows the hate that the suffragists had for the suffragettes and their opinion of what their actions are doing to their main cause.

Gyri and Sulci of the Brain

The brain has a unique appearance that consists of many ridges and indentations. A brain ridge is known as a gyrus (plural: gyri) and an indentation or depression is a sulcus (plural: sulci) or fissure. Gyri and sulci give the brain its wrinkled appearance. The cerebral cortex, or the outer layer of the cerebrum, consists of gyri that are typically surrounded by one or more sulci. The cerebral cortex is the most highly developed area of the brain and is responsible for higher brain functions such as thinking, planning, and decision making. Key Takeaways: Brain Gyri and Sulci Gyri and sulci are the folds and indentations in the brain that give it its wrinkled appearance.Gyri (singular: gyrus) are the folds or bumps in the brain and sulci (singular: sulcus) are the indentations or grooves.Folding of the cerebral cortex creates gyri and sulci which separate brain regions and increase the brains surface area and cognitive ability.Gyri and sulci form boundaries within and between the lobes of the brain and divide it into two hemispheres.The medial longitudinal fissure is the sulcus that separates the left and right brain hemispheres. The corpus callosum is found within this fissure.An example of a gyrus is Brocas gyrus, an area of the brain that orchestrates speech production. Gyri and Sulci Functions Brain gyri and sulci serve two very important functions: They increase the surface area of the cerebral cortex and they form brain divisions. Increasing the surface area of the brain allows more neurons to be packed into the cortex so that it can process more information. Gyri and sulci form brain divisions by creating boundaries between the lobes of the brain and dividing the brain into two hemispheres. Lobes of the Cerebral Cortex The cerebral cortex is divided into the following four lobes that each serve several important functions. Frontal lobes: The frontal lobes are located in the front-most region of the cerebral cortex. They are vital for motor control, thinking, and reasoning.Parietal lobes: The parietal lobes are positioned above the temporal lobes near the brains center and they process sensory information.Temporal lobes: The temporal lobes are positioned behind the frontal lobes. They are important for language and speech production as well as memory and emotion processing.Occipital lobes: The occipital lobes sit at the posterior region of the cerebral cortex and are the main centers for visual processing. Gyri and sulci are very important features of the central nervous system. Folding of the cerebral cortex creates these ridges and grooves which serve to separate brain regions and increase cognitive ability. Brain Sulci or Fissures Below is a listing of several key sulci/fissures in the brain and the divisions they create. Interhemispheric (Medial Longitudinal Fissure): This is a deep furrow located down the center of the brain that separates the left and right brain hemispheres. The corpus callosum, a wide ribbon of nerves, is located within this fissure.Fissure of Sylvius (Lateral Sulcus): This deep grove separates the parietal and temporal lobes.Central Sulcus (Fissure of Rolando): This sulcus separates the parietal and frontal lobes.Collateral Sulcus: This furrow separates the fusiform gyrus and the hippocampal gyrus on the lower surface of the temporal lobes.Parieto-occipital Sulcus: This deep crevice separates the parietal and occipital lobes.Calcarine Sulcus: This groove is located in the occipital lobes and divides the visual cortex. Brain Gyri Listed below are a number of important gyri of the cerebrum. Angular Gyrus: This fold in the parietal lobe is the area of the brain that assists in processing auditory and visual stimuli. It is also involved in language comprehension.Brocas Gyrus (Brocas Area): This area of the brain, located in the left frontal lobe in most individuals, controls motor functions involved with speech production.Cingulate Gyrus: This arch-shaped fold in the brain is located above the corpus callosum. It is a component of the limbic system that processes sensory input concerning emotions and regulates aggressive behavior.Fusiform Gyrus: This bulge, located in the temporal and occipital lobes, consists of lateral and medial parts. It is thought to play a role in facial and word recognition.Hippocampal Gyrus (Parahippocampal Gyrus): This fold on the inner surface of the temporal lobe borders the hippocampus. The hippocampal gyrus surrounds the hippocampus and plays an important role in memory.Lingual Gyrus: This coil of the occipital lobe is involved in visual proc essing. The lingual gyrus is bordered by the calcarine sulcus and collateral sulcus. Anteriorly, the lingual gyrus is continuous with the parahippocampal gyrus and together they form the medial portion of the fusiform gyrus.
