...to Life Science 5/07/2013 For this assignment made me think a lot about the things that a lot of great men and woman have done scientifically before I start this assignment I want to tell you about some great people that I admire in the scientific world. Those are some of the scientist that I admire first one is Albert Einstein developed the special and general theories of relativity. In 1921, he won the Nobel Prize for physics for his explanation of the photoelectric effect. Einstein is generally considered the most influential physicist of the 20th century. Another one is Gorge Washington Carver; Carver was born into slavery in Diamond, Missouri, around 1864. The exact year and date of his birth are unknown. Carver went on to become one of the most prominent scientists and inventors of his time, as well as a teacher at the Tuskegee Institute. Carver devised over 100 products using one of these crops the peanut including dyes, plastics and gasoline. Since I took this course science had made me think about my life a lot Science has improved my life in many ways. First, it's given me a safe and reliable means of controlling my reproductive choices. It's improved my understanding of the nutritional needs of my body and what I feed my daughter. Science has provided many of the modern day conveniences that have become essential to my life like electricity, car, and wireless devices. Science has also...

...Penicillin is an anti-biotic that was discovered by Dr. Alexander Fleming. Penicillin has helped save millions of lives and was a major advancement in the field of medicine and science. Penicillin played a major role in World War II and helped save the lives of soldiers. Penicillin was the first anti-biotic discovered. Penicillin was a remedy for bacteria. This was a new idea because before Penicillin there was no cure for bacteria and you often died of infections and bacteria. The discovery of Penicillin was not done on purpose. Dr. Alexander Fleming came back from vacation and discovered Penicillium Notatum. This discovery would lead to the anti-biotic, Penicillin. Dr. Alexander Fleming was not the only person who worked on the study of Penicillium...

... In partial fulfillment for the requirements for Research Work, this research entitled VINEGAR BATTERY has been prepared and submitted by Patricia Gian A. Nato who herby recommended for acceptance and approval for examination. MR. GEROMEL MARCOJOS SCIENCE MENTOR INTRODUCTION We say that Vinegar is useless because it is just used in the kitchen but Vinegar can be made from almost anything which contains sugar or starch. It is made from many different things; fruits, grains, roots even wood. In the technique called FERMENTATION, it can be made directly from sugar but is best made by first converting the sugar into alcohol and then turning the alcohol into vinegar. The conversion from starch is a little trickier, but the process shares a lot of similarities. We all know that the world is now facing an energy crisis and everyone is trying to do something about that. Now you can show everyone that electrical energy or electricity can be made from air and vinegar. After all, vinegar are freely available everywhere. If you wanted to save money from paying large amount of bill , this product will assure you That even a small amount of vinegar will not be wasted because this product is made of Vinegar . In this study , the researcher discovered that Vinegar is not just for preserving food or to use as a salad dressing. There are many healing functions that you can use it for. It cleans and sanitizes, it deodorizes and is a natural way to...

...Antoinette Watson CJS/215 December 7, 2015 Denise Mowder Forensic Science is the implementation of science and technology in the criminal justice system, which enforced by police agencies. To break down the definition of forensic science, forensic means the key to solving crimes. Science indicates the source of technology that used to help the forensic team to investigate the evidence and solve crimes. The history and development have come to long ways. There are many roles of the forensic science expert as well as the multi-capabilities. Forensic science began with a manuscript titled Yi Yi Ju (“A Collection of Criminal Cases”), in the third century in China. The report showed how a coroner was able to prove a woman was guilty of murdering her husband when in fact she claimed his death was accidental. By a simple experiment that done with two pigs. After, the official had informed the woman about the evidence that found, they were able to get a confession out of the wife. The Chinese were the first to identify an individual by their latent fingerprints and early eighteenth centuries, it was circumscribed education of anatomy and pathology restricted the growth of forensic science. In 1686 a professor of anatomy by the name of Marcello Malpighi at the University of Bologna in Italy. He was the first to record fingerprints characteristics. However, that was not a form of identification at that time. More than a century later, the first scientific paper developed...

...University Lab Research Report Research in the physical sciences has often been limited by our abilities of safety observing and studying the phenomenon in question. Even before the thought of microscopes, it would have been impossible to comprehend the composition of the most basic cells. The exact issues are the current issues in the field of physical science today, but it’s particularly true in the world of physics. While new technologies exist to measure phenomenon, it is not always safe to do so in the field that deals with radiation, unstable compounds, particles and atoms. As a result, the technology that we have in the field of physics, but across the board in the physical science field of astronomy, chemistry, physics and earth science. Challenges in Measurements Over the years there have been many adventures that allow for direct measurements within the field of physics, there are still many obstacles and challenges to making direct observations. Physics is the study of energy and matter and the interaction between-both of which are impossible to observe with the naked eye. The first major challenge in making direct measurement in physics is the size of the particles being studied. To solve this issue, physicists study these particles indirectly through things like associated radiation, their energy, or the displacement of other atoms. Almost all measurements that have been made on atoms or subatomic particles has been the result of indirect measurement...

...C. Clarke was born in Minehead, Somerset, England, and grew up in Bishops Lydeard. As a young lad, he enjoyed star gazing as he lived on a farm. He read a lot of science fiction magazines to add on to his upbringing. He gained his secondary education at Huish Grammar school in Taunton. At the school, he would write science fiction papers and magazine articles whichthat got featured in magazines and the schools papers. This town is important to his childhood because this is where he discovered the Taunton library. He visited daily to get new books, he borrowed W.Olaf Stapledon’s last and first men. He said “no other book before had such an impact on his imagination.” That being said I would be confident in saying his genius would likely be linked...

...Rebecca Walker Forensic Toxicology CRJ 311 Dawn George 4/22/2013 History Forensic science is defined as the application of science to the law. There are different types of forensic science, and each plays an integral part in the criminal justice system. Forensic biology usually involved DNA testing and its results. Forensic anthropologists examine human remains that have become skeletons in an attempt to determine how long the remains have been in a location and to try to determine a possible cause of death. Forensic toxicology falls into the category of forensic chemistry. Forensic toxicologists study toxins, drugs, poisons, alcohol, and other things found in the blood or tissues of crime victims or perpetrators. Forensic toxicologists study the blood and tissues of living people as well as deceased persons. The rapid advancement of technology in the last century and, in particular, the last three decades, has helped forensic scientists solve many crimes, even those that had been cold for decades. Technology is quickly changing and improving the methods by which crimes can be solved. The first evidence of scientific methods being used to identify people occurred in China in 700BC. Chinese artists used fingerprints to identify pieces of art they had produced. Of course, there was not computerized system to file or categorize these fingerprints. However, this is the first known instance of fingerprints being used for identification purposes. Clearly, things...

...“friends” and provide drinks that contained cyanide which ultimately ended their lives. Van did not discriminate when it came to her targets in some cases. It is estimated that Van killed thirteen people during the years of her killing spree, among the thirteen people she killed included was her mother-in-law, brother-in-law, and two ex-husbands. It is speculated that the killing of the members of Van’s extended family was due to ongoing family problems. Van’s main goal for the selection of her targets and killing them was to take their most valuables items for her possession or sell them for the money. It is estimated that Van was able to steal more than twenty thousand US dollars from her victims. Because of the nature of these killings it made finding out that Van was the killer hard. It is without a doubt that had it not been for the expertise of a Forensic Toxicologist Van would have continued killing in the manner that she chose to take the lives of her unassuming victims. In cases such as this it takes the skill of a Forensic Toxicologist to search beyond the scope of what the average investigator is trained to see in the evidence that is provided to them. This type of evidence gathering requires in-depth experimental testing to the tissues and organs...

...interstellar space. It can contemplate the meaning of infinity, ask questions about the meaning of its own existence, about the nature of God. 0:34And this is truly the most amazing thing in the world. It's the greatest mystery confronting human beings:How does this all come about? Well, the brain, as you know, is made up of neurons. We're looking at neurons here. There are 100 billion neurons in the adult human brain. And each neuron makes something like 1,000 to 10,000 contacts with other neurons in the brain. And based on this, people have calculatedthat the number of permutations and combinations of brain activity exceeds the number of elementary particles in the universe. 1:01So, how do you go about studying the brain? One approach is to look at patients who had lesions in different part of the brain, and study changes in their behavior. This is what I spoke about in the last TED.Today I'll talk about a different approach, which is to put electrodes in different parts of the brain, and actually record the activity of individual nerve cells in the brain. Sort of eavesdrop on the activity of nerve cells in the brain. 1:22Now, one recent discovery that has been made by researchers in Italy, in Parma, by Giacomo Rizzolatti and his colleagues, is a group of neurons called mirror neurons, which are on the front of the brain in the frontal lobes. Now, it turns out there are neurons which are called ordinary motor command neurons in the front of the brain, which have been known for...

...Topic: What begins people’s discovery of science? Thesis: “Hypotheses non fingo,” Newton confidently claimed. Therefore, he arbitrarily excluded the “hypothesis” from the experimental philosophy. Affected by him, more and more remarks neglected the importance of the “hypotheses” since then. As a result, it becomes a common view that discovery should proceed from analytic methods stricto sensu. Then, what is the real definition of hypothesis in Newton’s opinion ? Will he believe in intuition? Therefore, I will try to explain the definition of both “hypothesis” and “intuition”, and then attach significance to the “intuition” to show how the intuition begins a new discovery of science and struggle to prove that sometimes, the intuition can be a quite strong power to lead us to reach our confirmations. Outline: 1. The moment when I realize the importance of the intuition (Faraday) 2. The definition of hypothesis and intuition 3. The supporter- Einstein (using his examples as detailed ones) 4. The other famous successful discoveries in four different fields: Physics, Chemistry, Biology, Geography (describing the main story of each example) 5. How should we treat the intuition? What should we do after the intuition? 6. The conclusion includes 1) The importance of the intuition, 2) The significant role it has acted in the history of science, 3) Its efficiency of finding a certain answer, 4) An interesting analogy to show the role of intuition Body: ...

...CHAPTER II RELATED LITERATURE: There have been several breakthroughs in this research of saltwater being converted into electricity. The first one presented is an accidental discovery made in the Erie, Pennsylvania, 2007. John Kanzius set on fire a vial with saltwater using a radio frequency generator. Kanzius was experimenting with desalinate seawater. While doing so, he found he could keep the water “burning” as long as it was exposed to the proper frequencies from his machine. Rustum Roy, a professor at Penn State University, tried this experiment in the lab at the university, and, to his surprise, it actually worked. He explained that the salt water wasn’t actually burning. It was, in fact, the radio frequency that helped weaken the bonds holding together the salt water’s constituents. Roy says that he will continue to investigate on this, and he can see the potential applications of this process of burning saltwater as a source of alternative energy. Another recent breakthrough in relation to this topic is the topic on Power Generation. A team of researchers from the US and China have discovered a new desalination process that could produce electricity and clean water. They did this by modifying a microbial fuel cell, which is used to desalinate saltwater into drinkable water. Bruce Logan from Pennsylvania State University says that desalination of saltwater uses a lot of electricity, but by using the microbial desalination cells, one can desalinate saltwater and produce...

...III. INTRODUCTION A. Background of the Study I. We all know that the world is now facing an energy crisis and everyone is trying to do something about that. Now you can show everyone that electrical energy or electricity can be made from air and saltwater. After all, both the air and the saltwater are freely available everywhere. These are the two things that we have plenty of them. technology for electricity has evolved over time, but the basic principles of positive and negative charges can be demonstrated by creating a simple battery with supplies around the house and from a small electronics or home improvement store. Also known as an air battery, a saltwater battery uses the positive and negative ions from salt in water to generate a small amount of energy, enough to power a small, low voltage light bulb. Metal electrodes can be fashioned from metal nails that are long enough to extend past the water line of the solution. B. Statement of the Problem II. Why does salt conduct electricity in Water? C. Significance of the Study III. Unfortunately, When we do this investigatory project, it can helps the society, they can do it by their self, you can do by your own, or by your groups in society. Our investigatory project is little bit harder and easy, but we can sure that we can help other people, if we can do this experiment. D. Scope and Delimitation of the Study IV. Unfortunately, the cost of the technology to convert the saltwater will cost...

...Manchester University's Institute for Science, believes cloning has immense benefits that will contribute to the world of science. Along with Professor Harris, I also believe that cloning has the capability of changing the world around us for the better. For instance, cancer, diabetes, heart disease, and AIDS are some of the lethal diseases in which people die from every single day. Namely, these diseases can be passed on into the next generation of our children. This problem could be avoided by using the method of cloning. In addition, our best and bravest soldiers who are sent into wars often times come back with missing limbs. These veterans can't walk without a prosthesis or can't feed themselves without a nurse. With this in mind, cloning would enable them to improve the quality of their life by letting them truly experience what goes on around them and that is why they would greatly appreciate the mechanisms of cloning. Additionally, cloning has the power to enable these individuals to live out their dreams and to continue to show their patriotism. In other cases, cloning could bring hope to a patient who is undergoing the transplant process, a tedious, difficult, and nonetheless expensive procedure. While it is true that thousands of people are saved each year by organ transplantation, even more die each year waiting while their...

... Alex was going on a vacation, to take time off from his job of growing bacterial cultures in little Petri dishes. He was studying the effects of mucus on Staph cultures in a somewhat grungy laboratory in London. He forgot to wash up his last batch before he went off, and when he came back two weeks later, he saw an amazing sight. A mold was all over the dish, but all the bacteria were dead. To cut a long story short, Alex, or rather Dr. Alexander Fleming, found the mother of all disease fighting drugs, Penicillin. Blown in by dust on his Staph cultures. Many years later, Dr. Fleming was touring a new sparkling medical laboratory in the US. The place was very impressive and well equipped and scrupulously clean. After the tour his host made the remark “If you worked here, think of what you could have invented?” Dr. Fleming’s response was short and...
