Time Travel Essay -- essays research papers fc

Time travel is feat thought by most to be impossible. After all time travel is what many science fiction movies are made of. Let us not forget such movies as â€Å"Back to the Future† or â€Å"The Time Machine.† Yet unlike those movies time travel is not necessarily fiction. â€Å"We are in our own time machines, our hearts are pumping blood, we're breathing, we are existing through time (at least until our own personal time machines seriously malfunction).† (Need help citing this!) Still surrounding this topic is a series of theories, and surrounding these series is a number of flaws. Theories and flaws that need to be explained to fully understand the idea of time travel. First things first we must state the basics.   Ã‚  Ã‚  Ã‚  Ã‚  To begin with throw away whatever you thought you ever knew about time travel. There is no such thing as working time machines, you can’t go back in time by falling into a black hole, and sitting in a tub of water is not going to change you molecular structure and send it back in time by having you float through a wormhole. Time travel is achieved through speed; theoretically you must reach close to light speeds to go forward in time and faster than light speed to go back in time, according to Einstein’s theory of relativity mind you. Einstein’s theory of relativity is the basis of all time travel theories (Davies 1), â€Å"The essence of his prediction is that time is not absolute and universal but depends on the observer’s state of motion.† (Davies ...

Children and Their Security Object Essay

Some younger children usually between the ages of 8 and 12 months will become very attached to an object for a few years. Most parents are familiar with the so-called â€Å"security blanket.† Sometimes it is the most stained blanket in a child’s collection. Other times, it is an old stuffed animal. Regardless of what inanimate object a child chooses as their beloved security blanket, it’s difficult to separate the two. There are many benefits and significance for a child to have a security object and numerous misconceptions on regarding the relationship between a young child and their security object. It is very beneficial for younger children to have a security object. Most children will grow attached to an object when they are starting to be weaned from their mother because that’s a very emotional time. This object helps the child get through this critical transition so it is not so horrible. Young children with security objects do not throw such a fit when they have to be left with other adults and children, because they feel like you are still with them through this stressful situation. The American Academy of Pediatrics suggests that a security blanket can be especially beneficial when incorporated into a child’s bedtime ritual (Roberts, 2011). attachments Having this object just personifies all the positive and comforting things in this child’s world. The relationship a child has with their security object is very significant to them emotionally and physically. Children will usually give their object a name and be devoted to it because it gets them through being away from their parents. Young children usually hate being left with someone when their parents have things to do they are so use to having them all the time so when a child has this object with them it makes them feel like they have a piece of their parents there with them. These objects give the child emotional support, a sense of security, and it helps make them feel safe through stressful situations. This object helps the child grow and become independent instead of dependent. Parents often have misconceptions about their child and their security object. Many parents have believed it is signs that the child has insecurities and weaknesses. A study done by Richard A. Passman, psychologist at the University of Wisconsin at Milwaukee, shows that children who possess a strong attachment to a security blanket demonstrate less anxiety in a stressful situation (Wikipedia, 2013). Another misconception is that security objects promote thumb sucking which that’s just another self soothe children use. To take a child’s security object away from them would traumatize them greatly. The child will outgrow this item by their selves when they learn to deal with stressful situations. The importance of the relationship between a child and their security object is so great and with this essay some of them have been explained. There is no need to be concerned about this object it is just there for a few years to pretty much give them their parent when their parent cannot be there. I hope this essay has explained enough of the facts about security object that parents will take into consideration all of the pros and the cons before they think badly about security objects and try to take them away. There are the benefits and the significance of a security object to a young child and it is very important not to believe the misconceptions about it because it will be a lot worse to take it away.

Biology Plant And Animal Responses - 2342 Words

13 Biology AS 91603 Plant and Animal Responses Plants Growth responses Tropisms Millar Tropisms are directional plant growth responses. The plant detects a stimulus and grows toward or away from it. The two most important are phototropism and gravitotropism (aka geotropism). Plant shoots (a newly growing shoot is referred to as a coleoptile) grow toward light. This is positive phototropism. The reason for this is to move them into the light they need for photosynthesis (i.e. to survive). So this lets them grow in a way that improves their survival chance The mechanism behind this: †¢ The tip of the coleoptile produces a chemical called auxin †¢ auxin is a hormone that stimulates the cells below the tip (called the zone of elongation) too expand, up to three times their original length †¢ exposure to light inhibits the production of auxin (it alters an oxidation process to change it into something useless) †¢ So on the side of the plant light shines on, much less auxin is produced. On the side with less light, more is able to be produced †¢ all the auxin produced travels down the plant into the zone of elongation †¢ the dark side has more auxin, so the dark side elongates more †¢ this bends the plant toward the light (referred to as curvature) Geotropism: geotropism is the movement relative to gravity. Plants roots do positive geotropism and the stems do negative geotropism This lets the plants roots grow down into theShow MoreRelatedGenetically Modified Organisms And Stem-Food Report1053 Words   |  5 Pagesdifferent species but can be the same.

This essay will explore Darwin’s research and contribution to science through insectivorous plants, which is where Darwin believed to be a link. Plants are often seen as immobile and unresponsive but Darwin saw them as ‘active with interesting behaviour’. Charles Darwin actually produced the first well-known book on carnivorous plants (Insectivorous Plants, 1875) and therefore offered the initial study into the topic. In this book he examines many species and identifies whyRead MoreEnergy, Metabolism, and Cells – Photosynthesis Cellular Respiration1026 Words   |  5 PagesBiology – Science 206 Energy, Metabolism, and Cells – Photosynthesis amp; Cellular Respiration John Carter August 11, 2013 1.
