Have you wondered why streetlights are yellow, or why the year 2000 cars have brighter headlights and they are a different color? Have you ever wondered how the indiglo light on your watch works, or why it glows green and not white? And did you know that same indiglo light can be used while frozen, dipped in water, bent in half, stepped on, or in hazardous environments. Lighting has changed over the last few years; there are advantages and disadvantages of different kinds of lighting.
Lighting has been around since time itself existed; the first kind of lighting was fire. Fire was used to warm the inhabitants, and to provide light; many primitive cultures would use burning torches to provide light for their excursions and pathways. Fire was the only true form of light they had other than the moon. Fire had many disadvantages, one was that fire depended on fuel and needed proper conditions to operate (no rain, minimal wind). Another disadvantage is that fire, if not handled properly, could result in a brush fire or even burn down their shelter. An advantage was it was efficient when conditions were correct. It provided an inexpensive form of lighting, and could be used for cooking and heating. Due to the persistent problem of limited fuel, inhabitants looked for a way to prolong the fuel. (Thwig 29-34)
The next step in lighting that followed was a candle. Candles offered one main advantage over the fire by itself, fuel. A candle was able to provide a long burning light and was relatively inexpensive to produce. Candles were originally made from whale fat. The flame would burn and would slowly use the wick as a fuel and would burn much slower because the wax slowed the burning down. (Thwig 35-49)
The next form of lighting that followed the candle was the oil lamp. The oil for the lamps was also made from whales. The oil was the primary fuel for the fire, it burned even longer than a candle, and was cleaner. The wick was submerged in oil with one side sticking out. The oil would travel up the wick to the exposed portion. When lit the wick would be saturated with oil and the fire would burn the oil on the wick. This form of lighting was a large improvement, many cites adapted to this technology. Cities would create streetlights from the lamps and they would be lit on a n...

Greek women in most modern movies are shown walking around anywhere and with freedoms they really did not experience during that time period. In Euripides’ Medea Bemoans the Condition of Women, there is an accurate depiction of what women in Greek society experienced. Such as when Medea complains about how she has to manage her husband, listen to him and not look when he starts to look for a companion, while she can’t look at anyone but her husband (Craig, Graham, Donald, Ozment, and Turner 94). The life of women and men differed considerably during the time Greeks. These thoughts of Medea show the emotional turmoil that she went through with the double standard, especially with the punishment of adultery being bad for a woman but it was expected of men to look for other women. This idea is similar to the one in the Code of Hammurabi which applies a double standard for adultery. Although there is a visible distinction between the standards of women and men, there is a visible change in the amount freedom women experience in
Medea's identity as a weak woman is emphasised at the very start of the play. It is made very clear that she has come to misfortune through no fault of her own and is powerless in her problem ("her world has turned to enmity"). Being unable to change her situation is an example of her portrayal as a weak woman figure. We are told that she has been crying for days ("lies collapsed in agony"). Soon after these descriptions of her weeping, the Tutor arrives and informs us that yet more bad news is coming her way ("not heard the worst" "banish them"). At this point all the pity is directed towards Medea, shunned by her husband and unable to control what is happening around her, instead crying uncontrollably ("shouting shrill, pitiful accusations").
Though she had a positive influence upon the women during her time, Medea is a true cynic. With her art of manipulation and her strive for vengeance, Medea becomes a killer who disregards even her children’s lives. In Ancient Greece, women were stereotypically regarded as weak and passive beings. But Medea, a woman during that era, contradicts what Greek society portrays women. She uses people’s feelings and lives as mere tools in order to push her agenda. A villain can be either a man or a woman, as gender is a mere shell of the true person inside.
The skeletal system also maintains the structure of the body and is the frame work of its shape. According to Elaine N. Marieb & Katja Hoehn, (2016), “The axial skeleton supports and protects, while the appendicular skeleton allows mobility.”
In “Stereotype and Reversal in Euripides’ Medea,” Shirley A. Barlow asserts that Medea is a foreign woman who does not want to accept to adapt to the labels that are placed on women of Greek society, unless it allows her to gain favor for her to accomplish her revenge on those who have ruined her life.
The light bulb is the way we see in the dark, the way we find our way, the way we know when to go at a stoplight. How did Thomas Edison achieve this invention? Knowledge. Knowledge of electricity and the needs of those around him. In The Great Gatsby, Daisy Buchanan claims that she wants her daughter to be “a beautiful little fool.” In other words Daisy is saying that ignorance is bliss. Some others believe that knowledge is power. The advancement from candles to light bulbs changed the culture entirely. People could easily do the work they needed to after sunset, and it even led to more inventions. We need knowledge to advance, and for this reason powerful knowledge is more valid than blissful ignorance.
The people of today greatly envy the ancient times. They study, idolize, and imitate its culinary, fashion, and social aspects due to believing these had been exemplary. As with any given time period, however, inherent flaws indeed existed, particularly concerning the society of Ancient Greece. Euripides, the renowned Ancient Greek playwright who lived in this period himself, recognized the existence of various social flaws and in suit wrote the allegorical play Medea in 431 B.C.E., a popular work studied by many in its current translation today. In the play, Euripides employs the protagonist, Medea, to provide transparency into the social flaws of Ancient Greek society and culture. He executes this by placing Medea into situations of discord with the king, her ex-husband, and the chorus to exploit the social flaws of abuse of power, male dominance, and blatant naivety in Ancient Greece.
Who I am as a person is the sum of my experiences, what I enjoy and the skills that I possess. From an early age I have always enjoyed the outdoors and find nature relaxing. My enjoyment of the woods has led to camping so many times that I have lost track, which has led to backpacking becoming one of my favorite ways to get out of the city and into the mountains, just myself and my dogs. As I grew older, my love for the outdoors
Throughout our lives, our bodies break down the old bone and it replaces it with new bone. But as age increases, more and more bone is broken down than what is replaced. The bones in our bodies are constantly changing and never stay the same. Special cells called osteoclasts, located in the body have the main function of removing bone. These are different from another special cell called osteoblasts, which are bone-forming cells. If a person does not have osteoporosis, there is a balance between these two cells in the bone. But if the person is osteoporotic, osteoclasts will remove the bone faster than the osteoblasts can form the new bone. This will result in a net bone loss. Do you know what a honeycomb looks like? That is what the inside of the bone normally looks like, but when a person has osteoporosis the looks change. The spaces inside the bone become a lot larger, this showing the loss of bone strength and density. The outside of the bone also thins, making the bone even weaker. Osteoporosis causes permanent changes in the bone. There are some basic mechanisms that are responsible for the development of osteoporosis such as poor bone mass acquisition during growth and accelerated bone loss in the time period after one’s peak bone mass is achieved. Both are related with genetic factors. The risk of fracture in postmenopausal women is mainly determined by the peak bone mass during premenopausal stage. Peak bone mass
Although Medea is seemingly about a woman who faces gender oppression, we must also take into consideration how her status as a queen impacts her perception of justice and revenge. Aristotle says that an insult is an action that causes shame to the victim, but is not done out of the need to advance oneself or for fun. According to Jason the marriage between him and his new wife is a gesture to provide a better life for his children. In this instance Aristotle understanding of the way an insult unfolds into revenge does not equate to the way it is portrayed in Medea. We must then question Medea's idea of justice and revenge as it relates to her status as a queen. Aristotle's understanding of belittlement as it regards to people with
Have you ever wondered why many elderly people walk slower and frequently complain about their aching bodies? While there may be many different medical reasons for these symptoms, one of the most common is Osteoporosis. Although I have yet to reach my twenties, I am not a stranger to this bone disease. I see the effects of Osteoporosis take a toll on my great-grandmother and great-grandfather. Their conditions have ignited my curiosity, making me eager to research and learn more about the disease from its causes, symptoms, effects, and treatments.

Medea provides us with an excellent analogy on her own exile and that of women who are alienated in life in general. Her suffering can be viewed as whole group, women suffering as a tragedy. We find Medea’s character at this time in the play to be one of revenge seeking for Jason breaking their oath of marriage. She has murder on her mind, but it was not until Aegeus, saw her revenge plot appropriately facilitated with him agreeing to allow her refuge in his country; complete with an oath (Fletcher). The author goes on to note that this was the second time that we have a female-authored oath, with eventually contributes to women controlling the textual strategy in the play, utilizing a seductive magic and tricky persuasions. In both situations, Medea was able to utilize her position, as she called it, a foreign woman without recourse. The effective use of oaths, not only allowed her safe sanctuary into Aegeus’s country, but the alliance eventually become a marriage in which she fulfills her promise that he would be able to bear a son,
There are many different types of lighting that impact the image. For example, there is natural lighting, ambient lighting, studio lighting and outdoor lighting. Natural lighting can be classified as outdoor lighting. Studio lighting is the typical lighting one uses when doing a photoshoot for a magazine. Studio lighting helps dramatize the image. Ambient lighting is “the general “man made” background light that softens any contrast” (Stubbs) Ambient
