Chemistry in Our Dailylife Essay Example for Free

Chemistry in Our Dailylife Essay Our entire universe is made up of matter which is constantly changing forms and evolving into other forms of energy. Chemistry is defined as the study or science of this ever changing matter. The other sciences which we study commonly like biology, physics and mathematics are all dependent on chemistry and are known as specific studies under the elaborate subject of chemistry. Since there is chemistry seen in biological forms as well as physical states of nature, there are subjects called biochemistry and physical chemistry which help study these changes. There are many chemical changes which occur around us everyday but we are never aware of them. But this is a great way of teaching children how magical the world of chemistry is! With these real examples you can teach them by taking a chemistry in everyday life quiz, as practical studies are always fun to learn. To make this job easier for you, mentioned below are a few such examples of chemistry in everyday life, take a look! Examples There are chemical reactions in daily life like, in the way you breathe, the food you eat, the water you drink and in every motion which is taking place around you at every second of the day. It is a very important and interesting concept which could be taught to your children as they have to know, how their world works. The best way to explain this to them is to show them practically how and why are a few things in nature the way they are! You can do this by demonstrating a few kids chemistry experiments for them. An essay on this topic can be a great start to teach these kids, what a wonderful thing, chemistry is. Find out what these intelligent mechanisms of nature are, that define presence of chemistry in daily life, read on. Water, which occupies 70% of the earths surface is made by two chemical elements, hydrogen and oxygen. Soap is an emulsifier which allows oil and water to mix and so the oily mixtures on body and clothes can be removed after application of soap and water. Chemistry in kids life can also include why vegetables are colored. Colored vegetables consist of chemical compounds called carotenoids which have an area known as the chromophore. It absorbs certain wavelengths of light and thus there are colored vegetables. Food is cooked because of the steam thats present either in the water added or that which is present inside the food items. Onions make you cry due to the presence of sulfur in the cells which break after the onions are cut. This sulfur gets mixed with moisture and thus irritates your eyes. You feel hungry because of the satiety center in your brain falls short of particular hormones to function and then sends the signal of hunger. You fall in love, get attracted and have a feeling of belonging because of certain monoamines present in your brain which get stimulated through nerve sensors. If you have wondered, why is the sky blue, it is due to a phenomenon called the Rayleigh scattering, which depends on scattering of light through particles which are much smaller than the wavelength. Hence when light passes through gases, there is scattering and the sky appears blue. Coffee keeps you awake because of the presence of a chemical called adenosine, in your brain. It binds to certain receptors and slows the nerve cell activity when sleep is signaled. Anaerobic fermentation is also a great concept which is present in the chemistry of everyday life. It is present in yogurt, breads, cakes and many other baking products. It is the multiplication of certain useful bacteria which increase the size of the food and make it more filling and soft. The food chain present in every ecosystem is also a major part of everyday life chemistry. Even though it has more biological background, it eventually works because of its chemistry. With these great examples, there is no other explanation of the existence of earth and its components other than chemistry. Thus, through so much to learn from, you can easily teach your children the importance of chemistry in our day-to-day life!

How Scottish families have changed in the last 100 years :: essays research papers

Perhaps the area that has changed the most for Scottish women in the last century is the family and the home. In the first half of the century the norm was for the woman of the house to "service" the male breadwinners within the home and family and to reproduce as their primary roles in life. This included many tasks including preparing meals for the whole family, looking after the family budget (It was usual for the husband to give his wife his pay packet at the end of the week and she would use it to pay the bills and buy the food.) as well as cleaning the house and the doing the whole family's washing, which all together usually equated to (or more than) full time work. Women were put under heavy strain due to cultural expectations and norms. They were expected to be under their family's beck and call 24 hours a day and while husbands could escape household pressures such as screaming children, by going to the pub with their friends, women could never even dream of that kind of freedom. Although their family was seen as a woman's main priority in life, many HAD to go out and work, often in factories or working as maids or cleaners (24% of employed women worked in the domestic service). They earned far less than men and were also expected to run the family home single handily. Although the 1911 Census of Scotland reported that only 1/20 of married women worked, the results were mainly linked to the middle class, not the poorer families where the woman was forced to work as their husbands wage wasn't enough to support the family. This was not uncommon, especially as in 1911, women who married between the ages of 22 – 26, had an average of 6 children (with 20% having 9 or more). In the first half of the 20th century, Scottish families remained larger than those in England did. One of the theories behind this is that Scotland has a smaller middle class, (who on average, have less children per family) and a higher proportion of Roman Catholics, who do not believe in birth control. Scottish homes were often very small with many children, and it was also common to find many "live-in" relatives in the home too. Conditions were cramped; in 1911, 50% of the population lived in 2 houses of only 1 or 2 rooms (bearing in mind that the average family size was at least 8).

History and Memory Essay Essay

Analyze the ways history and memory generate compelling and unexpected insights Representing an ‘absolute truth’ is impossible. Inherent human bias affects both history and memory. We unintentionally falsify parts of the past in order to emphasise the nature of past events we find central to our individual beliefs. Therefore we are challenged with obvious limitations in representing the ‘truth’. The interplay of history and memory however, leads to a rather satiable and tangible level of truth. Nonetheless, it is yet to be seen that this satisfiable level of truth will be riddled with bias as it is human nature to have an opinion/perspective that makes reconciling (accepting) memory and history a great challenge. Ultimately, this satiable level of truth creates compelling and unexpected insights into the past as assumptions that have previously been thought as true and views can change when face with uncertainty (or challenged by evidence). Mark Baker’s biographical novel The Fiftieth Gate highlights his confrontation with the terror of his parents’ childhood. Similarly, ‘Big Fish’ composed by Tim Burton which explores the strained relationship between a father and son both express the ways both history and memory generate compelling and unexpected insights. Individual’s often feel compelled to an empirical representation of past events, this is evident as Mark Baker, a man who predominately believes in precision and order which is conveyed as he â€Å"collects his memories in colour coded photo albums† so it is obvious that he has an assumption that History unlocks the past and contains all the answers in his search for the absolute truth. Furthermore, the confession that Mark â€Å"believed the soviet records more than his own mother† which was hard for the composer to accept, due to the fact that Mark feels compelled to believe the empirical representation of events rat her than the figurative/ emotional representation of the truth and therefore creates an unexpected insight into what Mark originally thought was a sterile representation of the truth. Similarly, Big Fish also expresses this viewpoint as the protagonist ‘William Bloom’ â€Å"wants to know the true version of things†. The dialogue previously mentioned articulates the need for a  factual/verified account of truth in which William demands of his father, a man who William feels he doesn’t â€Å"know about as he hasn’t said a single fact†. Consequently, the thirst William has for knowledge that is definite and unrefutable, leads him to be compelled when he finally understands the man his father is. Therefore, the often unexpected insights challenge individual notions of representing truth and not just verify what happened. However, the figurative representation can be more powerful that the facts alone. This is particularly apparent throughout this biographical novel with the expression â€Å"It always begins in darkness, until the first light illuminates a hidden fragment of memory†. The chiaroscuro represented in this quote communicates the idea that memory is stored away until a physiological trigger releases the fragment of memory which is imparted as Yossl (Mark’s father) walks throughout the Jewish Graveyard reliving the memories of his childhood with his deceased friends. Ultimately, this creates a compelling and unexpected insight as the majority of people visit the graveyard to commemorate and mourn the death of their beloved. Additionally, Big Fish also supports this statement as the need for figurative representation far outweighs the need for an empirical one. The statement â€Å"All the facts but, none of the flavour† represents the notion of embellishing the truth to provide not only a moralistic and emotive perspective but one of entertainment also. The figuratively, compelling insight of representation entertains the individual and therefore may render this representation more powerful than an empirical one. Consequently, the figurative can sometimes capture and compel the individual more than the verified facts alone. Lastly, reconciling an empirical representation with the figurative can piece together a satiable level of truth. â€Å"I was searching for her history in order to vindicate her stories† indicates the desperate ne ed that Mark Baker had to reconcile his mother’s memory through the use of history. The movie Big Fish supports this view through the use of dialogue. â€Å"They have two completely different personalities but the same set of legs† ironically can be expressed as a personification of both history and memory. The dialogue creates a compelling and unexpected insight as it conveys that history and memory are both created from humans; however they are seen to be completely different in the respect that history is factual and evidence based while is personal and often emotive. The  combination of the two interplay in Despite human nature’s imperfections in representing an ‘absolute truth’, when we accept the limitations and reconcile the subjective and objective perspectives a satiable level of truth is achievable.

Life of Pi Essay - 643 Words

In the book Life of Pi, by Yann Martel, the main character gets stranded in a lifeboat in the Pacific Ocean with only his imagination to cope with. Piscine Molitor Patel, also known as Pi, uses a figure of his imagination to make a horrific situation better, by changing his perspective on the entire ordeal. When Pi gets isolated with his mother, a cruel cook, and an injured sailor, Pi transforms all of them into animals out of fear, disbelief and justification. Throughout Pi’s experience, he is very fearful. He is not only afraid of all the death cruelty around him, but of himself as well.

The story replacing humans as animals, was a way for Pi to justify his actions. Pi stated in the book, â €Å"Then we fought and I killed him† (310), which is a confession of murder.

By changing everyone into animals and creating Richard Parker, Pi made himself sound like he took no part in any man slaughter. Confession of murder was also very dangerous because he could have been sentenced to jail as he was telling his traumatic tale to the two police officers. If Pi hadn’t had a way to justify the actions he was taking in the lifeboat, he wouldn’t have found a way to cope and could have let himself die. It was through his justifications that he found comfort and longing to survive, which led him to stay alive for two hundred and twenty seven days in the middle of the Pacific Ocean.
