3D Printing for Educational Purposes

3D Printing for Educational Purposes 3D Printing for Educational Purposes Can’t Imagine Abstract Things? Just Print Them! 3D printing is a hot topic in education these days, and this ever-developing technology is helping students grasp abstract topics and ideas. From fine arts to math, universities everywhere are using 3D printers in the classroom – and here’s why! 3D Printing – It’s an Art! From Sculpture 101 to culinary school, 3D printers are being used more and more within the arts, and with amazing results. Architecture students can use the printers to recreate their designs, allowing them to examine how their structures will look in the real world and make immediate tweaks and changes to improve their designs. At culinary institutes, students can design new and different cupcake and loaf pans, cookie cutters, and decoration molds, ensuring that they are able to stay at the forefront of food aesthetics. Turning the Abstract into Concrete Math is full of abstract and theoretical ideas that can be challenging for students to grasp. Using 3D printers to visualize and create mathematical concepts, shapes, and curves makes it much easier for students to understand how a theorem or shape actually appears in reality. 3D printers also make it easier for professors to effectively teach these ideas, as they ensure that both audial and visual learners have an equal footing in the classroom. Engineering New Ideas Many engineers pride themselves at being at the forefront of technology and innovation, so it only makes sense to have the latest technology – such as 3D printers – in the classroom. Students can learn from this new manufacturing technology itself, as well as utilize it for their own designs and to solve engineering problems. Using a 3D printer to create prototypes can help students to actually test their engineering skills and to physically see where improvements may be needed. Students can also see how existing parts, such as the various components of a car engine, may be modified – they can then print and test these, thereby creating innovation within the engineering industry through printing! Anatomy (Past Present) in 3D The human body is one of the most complex machines on the planet, and students everywhere – be them freshman biology students or final year medical students – are learning about anatomy through the use of 3D printers. By creating 3D images and cross-sections of organs, nerve systems, and the brain, students have one of the most effective study aids on the planet! In addition to the workings of the human body, 3D printing can also help archaeology students to examine artifacts, skeletal remains, and fossils in greater detail. By printing such artifacts, students are able to physically handle what would normally be ‘hands-off’ materials from museums, exhibitions, and archaeological digs. What were once abstract concepts and 2D pictures or diagrams are suddenly brought to life in the classroom using 3D printers, helping students become better learners and critical thinkers. Whatever you’re majoring in, it’s likely that a 3D printer will be coming to your classroom soon! The advantages it gives to both students and professors make this an important tool for learning across the arts and sciences – hopefully you’ll get to try one out for yourself!

The Agents of Erosion

The Agents of Erosion The process known as weathering breaks up rocks so that they can be carried away by the process known as erosion. Water, wind, ice, and waves are the agents of erosion that wear away at the surface of the Earth. Water Erosion Water is the most important erosional agent and erodes most commonly as running water in streams. However, water in all its forms is erosional. Raindrops (especially in dry environments) create splash erosion that moves tiny particles of soil. Water collecting on the surface of the soil collects as it moves towards tiny rivulets and streams and creates sheet erosion. In streams, water is a very powerful erosional agent. The faster water moves in streams the larger objects it can pick up and transport. This is known as critical erosion velocity. Fine sand can be moved by streams flowing as slowly as three-quarters of a mile per hour. Streams erode their banks in three different ways: 1) the hydraulic action of the water itself moves the sediments, 2) water acts to corrode sediments by removing ions and dissolving them, and 3) particles in the water strike bedrock and erode it. The water of streams can erode in three different places: 1) lateral erosion erodes the sediment on the sides of the stream channel, 2) down cutting erodes the stream bed deeper, and 3) headward erosion erodes the channel upslope. Wind Erosion Erosion by wind is known as aeolian (or eolian) erosion (named after Aeolus, the Greek god of winds) and occurs almost always in deserts. Aeolian erosion of sand in the desert is partially responsible for the formation of sand dunes. The power of the wind erodes rock and sand. Ice Erosion The erosive power of moving ice is actually a bit greater than the power of water but since water is much more common, it is responsible for a greater amount of erosion on the earths surface. Glaciers can perform erosive functions - they pluck and abrade. Plucking takes place by water entering cracks under the glacier, freezing, and breaking off pieces of rock that are then transported by the glacier. Abrasion cuts into the rock under the glacier, scooping rock up like a bulldozer and smoothing and polishing the rock surface. Wave Erosion Waves in oceans and other large bodies of water produce coastal erosion. The power of oceanic waves is awesome, large storm waves can produce 2000 pounds of pressure per square foot. The pure energy of waves along with the chemical content of the water is what erodes the rock of the coastline. Erosion of sand is much easier for the waves and sometimes, theres an annual cycle where sand is removed from a beach during one season, only to be returned by waves in another.

Can the United States Continue to Run Current Account Deficits Essay

Can the United States Continue to Run Current Account Deficits Indefinitely - Essay Example ates like China and Japan have afforded the United States with inflows that have made it possible for the United States to increase its current account deficit. However, analysts are of the opinion that the rising level of United States current account deficit may become unsustainable and risky thus make the large foreign investors consider shifting their investments in the United States loan securities away to other nations. It is also likely that the consequence of the persistent United States foreign debt may be making it a politically weak nation and reliant to large investors like China. According to Carbaugh (2011), the purchase of the United States current account deficit can continue indefinitely because the desire of foreigners for the American loan assets may not stop. The United States has a history of having run current account deficits continuously from 1820 to 1875 (McKinnon, 2001). Its economic growth by then solely remained reliant to foreign debts. Furthermore, the United States saving rate is lower than that of its main trading partners like China and Japan. All these factors make the United States current deficit likely to be persistent indefinitely as long as they remain

HYPNOTHERAPY & NEURO LINGUISTIC PROGRAMMING Essay - 1

HYPNOTHERAPY & NEURO LINGUISTIC PROGRAMMING - Essay Example Therefore, all the suggestions are entered to the subconscious without conscious intervention. Once conscious faculties are sure that monotonous stimuli unlikely to endanger their subject, they become complacent and irresponsible. With attention gone there can be no conscious intervention which leads to the state of conscious suspension. Conscious faculties are alert and vigilant to check the security or any danger from external stimuli. Therefore, the conscious faculties intervene when suggestions are on their way to the subconscious. To produce monotony to the sense of feeling, the subject should be made very comfortable by reducing all possible external stimuli. The pressure on the subjects body should be released by avoiding any unpleasant sensation commonly known as pins and needles. The subject should be instructed to sit properly without the legs crossed. The room environment should be calm and temperature should be maintained at constant level. If the emotional force generated by thoughts or perceptions is not discharged through appropriate action, the pressure will build up and escape where it finds least barrier. If it is not discharged, building of such a force might lead to destructive level of pressure. Hypnotist displays posters before his performance which claims to possess mysterious hypnotic powers, the power to control minds, and the power to control the actions of others. At the actual show, special stage props, a carefully planned presentation, and the impressive appearance of the hypnotist, all play a part in contributing still further to building up emotion in the audience. In normal situations the emotion is discharged through appropriate action. The builded pressure escapes where it finds least barrier. When the asserting pressure is moderate, feelings such as satisfaction, dislikes etc. are released. It can render the conscious faculties inefficient and incapable of carrying out their normal duties. In our working model of the

Experiential Learning Essay Example for Free

Experiential Learning Essay Growing up in a southern state with traditional family and religious values has made transitioning into college life a bit difficult. Questioning myself and my own bias from my experiences in life is an ongoing process, as I wonder â€Å"is it me? † or its possible that I feel strongly about issues because my values and ethics overshadow all. I feel as if I move from a state of passive to aggressive in my actions just as I do my own state of internal feeling of who I am. Sometimes I feel like I have been treated unfairly both as a child and now, simply for being female. In my actions I sometimes pretend that this does not bother me and that a woman’s place is in the home, being a good mother and wife, bit other times I lash out when this is expected of me from my church, family, and some facets of society. I struggle in this passive aggressive way in my own religion too. As a Baptist, sometimes I feel like the teachings are true and correct and that social issues, such as homosexuality are undesirable and need to be â€Å"fixed†. Other times, however, I feel like homosexuality and other so-called social issues brought up in the church should not be treated like diseases and we have no business trying to â€Å"cure† others. Growing up white, female, and very religious, I was taught ideals that seemed to contradict themselves. The most notable cases were of people in poverty. We were not a poor family, but I would see a great majority of people in my state of Tennessee living in very unpleasant conditions. From teachings of the church and my family, I was taught to help those, who cannot help themselves. But, the irony was that most conservative people around believed that everyone could help themselves and that their state of poverty was simply due to laziness. I remember thinking that I was just a kid and had no control over my home life and that these other impoverished kids I would see could not help their situation any more that I could. So it was confusing that no one seemed to go out of their way (with a few exceptions) to help poor people back home. We were, also, expected to treat people equally and not have any â€Å"hate in our hearts† for anyone for any reason. It wasn’t obvious to my friends and I that our parents were in any way bigoted toward minorities, because they didn’t use racial slurs or openly discuss their dislike for other races. But, when my friends and I started becoming older and noticing boys, our parents wouldn’t hide their shock when we said that we had an attraction for a boy of another race. Then I realized that my parents did not believe in interracial relationships and for awhile I thought that it was not racist, but now I see that my upbringing was all twisted together with racism, sexism, and contempt for the poor and homosexuality. Like many southern girls, I was supposed to find a nice man to marry and going to college was the way to find this man. My family and the society I grew up in had all these expectations of me, hidden agendas, and covert prejudices that I am still trying to understand fully. I want to be treated like an intelligent woman, whose ideas have merit. I get so angry and feel aggressive when people believe that college is just a â€Å"hobby† and that I am here just to find â€Å"Mr. Right†, I am tired of all the years of playing the passive role of the quiet and complacent â€Å"southern belle†. I, also, want to widen my base of friends to include people who do not let religion become a barrier to their lives. Many times from what I have seen in the church, people mindlessly believe what the preacher says and don’t take time to understand that everyone is human and should be treated fairly. I wish I had the courage to go to speak to people, who are homosexual, but I still can’t. This is one of the goals I am working on now.

Tycho Brahe :: Essays Papers

Tycho Brahe Tycho Brahe provided a great deal of information to the science community and will never be forgotten. Brahe had a large influence on the Scientific Revolution and its happenings. Many people in the time of Brahe believed that what is discovered through the Scientific Revolution, about the world, is the truth. Also at this time people believed that the Bible or their faith would surely out weigh reason that was brought by the Scientific Revolution. The are many things that make up Tycho Brahe the person, like his family. Brahe’s family is of old and distinguished nobility. Members of Brahe’s family served the king and their country, in council and on the battlefield. 1 Tycho, the first born son to Otte and Beate Bille-Brahe, in December 1546. Tycho parents named him after his grandfather. Brahe’s childhood made also made up an important part of who he is. Brahe studied law and philosophy at the universities of Copenhagen and Leipzig. Each night after his long day of studies, Brahe would always be found looking at the stars in the night sky, before he went to bed. This some people would say, played a large role in what Brahe should do with his future. Brahe is said to be a colorful character when he is in school. "He allegedly challenged a fellow student to a duel with swords in a dispute over who was the better mathematician. Brahe's nose is partially cut off, and he was said to wear a gold and silver replacement upon which he would continually rub oil."2 After Brahe’s wonderful education he would begin his journey to find out more about the sky and all that is in it. In 1972 Brahe discovered a supernova in the constellation Cassiopeia. "Brahe's meticulous observations showed that the supernova did not change positions with respect to the other stars (no parallax). Therefore, it was a real star, not a local object."3 This is early evidence against the immutable nature of the heavens.4 "In 1577 his studies of a bright comet showed that it traversed the spheres of the planets, and was not an atmospheric exhalation or an ill omen. Both these phenomena contributed to growing dissatisfaction with the Aristotelian belief in the perfect and unchanging nature of the celestial spheres."5 Brahe spent most of his time traveling and lecturing about his discoveries that he would make.

Perceptions of African American Women Essay

It was amazing to know that Dr. Mae C. Jemison who happens to be the youngest of three children born to a middle class African American family, Charlie Jemison, a maintenance worker and his wife, Dorothy, a teacher. Dr. Mae C. Jemison was the first black woman astronaut to be in space in an era filled with segregation and racism, she is a Chemical engineer, scientist, physician, teacher and astronaut, she has a wide range of experience in technology, engineering, and medical research. In addition to her extensive background in science, she is well-versed in African and African-American Studies, speaks fluent Russian, Japanese, and Swahili, as well as English and is trained in dance and choreography. Dr. Mae C. Jamison was an inspiration to me, and probably to many African American women. She was full of resilience and determination especially to have reached and achieved success in an unusual field of endeavor for many African American women, I applaud her determination to make a difference among the African American women and blacks in Diaspora. After graduating from Morgan Park High School in 1973 at the age of 16, Dr. Mae Jemison earned a BS in Chemical Engineering from Stanford University, while also fulfilling the requirements for a BA in African-American Studies. After earning these degrees in 1977, she attended Cornell University and received a Doctor of Medicine degree in 1981. During medical school she traveled to Cuba, Kenya and Thailand, providing primary medical care to people living there. This is an indication of her humanitarian efforts and eagerness to reach out to the less privileged population. Having a desire to do more with her life, she enrolled in graduate classes in engineering and applied to NASA for admission to the astronaut program. She was turned down on her first application, maybe because she is a black woman, but she persevered and in 1987 was accepted on her second application. She became one of the fifteen candidates accepted from over 2,000 applicants. When Dr. Mae Jemison successfully completed her astronaut training program in August 1988, she became the fifth black astronaut and the first black female astronaut in NASA history. In completing her first space flight, Dr. Mae Jemison logged 190 hours, 30 minutes, 23 seconds in space, making her the first African-American woman in space. She says, â€Å"I had to learn very early not to limit myself due to others’ limited imaginations. I have learned these days never to limit anyone else due to my limited imagination. † This is an inspiration to other blacks in general who normally assume a second class citizen and believe that they will never do well or will be appreciated in whatever they do. This is a wake-up call, and manifestation of the saying â€Å"Determination is the mother of invention†. In 1993, Dr. Mae Jemison resigned from NASA and founded the Jemison Group, Inc. to research, develop and implement advanced technologies suited to the social, political, cultural and economic context of the individual, especially for the developing world. Current projects include: Alpha, (TM) a satellite based telecommunication system to improve health care in West Africa; and The Earth We Share, (TM) an international science camp for students ages 12 to 16, that utilizes an experiential curriculum. Among her current projects are several that focus on improving healthcare in Africa. She is also a professor of environmental studies at Dartmouth College. Dr. Mae Jamison made a name for herself and name for blacks in general; Her entrepreneurial spirit put her in the limelight and acts as a boost to determined black men and women in Diaspora. Ellen Johnson-Sirleaf. It was quite surprising to read about Ellen Johnson-Sirleaf, I know almost nothing about this â€Å"giant and queen of modern Africa† who is presently the current president of Liberia. According to what I have read so far about this â€Å"queen of Africa† she was born In Monrovia, the capital of Liberia on October 29, 1938. During this period, Liberians had no clue that the First female president of an African country had been born into their mist. Ellen Johnson-Sirleaf is a daughter to descendents of original colonists of Liberia (ex-African slaves from America, who promptly on arrival set about enslaving the indigenous people using the social system of their old American masters as a basis for their new society). These descendents are known in Liberia as Americo-Liberians. From what I read, I noticed that Ellen Johnson-Sirleaf was truly an intellectual power house, a charismatic leader and destined to make a change in Liberia and contribute her quota in Africa. From 1948 to 1955 Ellen Johnson studied accounts and economics at the College of West Africa in Monrovia. After marriage at the age of 17 to James Sirleaf, she travelled to America (in 1961) and continued her studies, achieving a degree from the University of Colorado. From 1969 to 1971 she read economics at Harvard, gaining a masters degree in public administration. Ellen Johnson-Sirleaf then returned to Liberia and began working in William Tolbert’s (True Whig Party) government. Ellen Johnson-Sirleaf also served as Minister of Finance from 1972 to 73, but left after a disagreement over public spending, this is an indication of her prudence and will power. As the 70s progressed, life under Liberia’s one-party state became more polarized to the benefit of the Americo-Liberian elite. On 12 April 1980 Master Sergeant Samuel Kayon Doe, a member of the indigenous Krahn ethnic group, seized power in a military coup. With the People’s Redemption Council now in power, Samuel Doe began a purge of government. Ellen Johnson-Sirleaf narrowly escaped – choosing exile in Kenya. From 1983 to 1985 she served as Director of Citibank in Nairobi. I will say that Ellen Johnson-Sirleaf had a lot of courage, because it was quite unusual for a woman to challenge a dictatorial incumbent president in Africa without being kidnapped, tortured or killed in the process, although She was later sentenced to ten years in prison. Ellen Johnson-Sirleaf spent just a short time incarcerated, before being allowed to leave the country once again as an exile. During the 1980s she served as Vice President of both the African Regional Office of Citibank, in Nairobi, and of (HSCB) Equator Bank, in Washington. Ellen Johnson-Sirleaf played an active role in the transitional government as the country prepared for the 2005 elections, and eventually stood for president against her rival the ex-international footballer, George Manneh Weah. Despite the elections being called fair and orderly, Weah repudiated the result, which gave a majority to Johnson-Sirleaf, Ellen Johnson-Sirleaf eventually became Liberia’s first elected female president, as well as the first elected female president in the continent Africa. . In 2005 She established a Truth and Reconciliation Commission with a mandate to â€Å"promote national peace, security, unity and reconciliation† by investigating more than 20 years of civil conflict in the country and in November 2007, she received the United States Presidential Medal of Freedom, the U.
