The laser is one of the most advanced tools we have in our civilization. Lasers are powerful enough to cut through a thick piece of steel, yet can be used in medical surgery. Lasers are used in the army, for guns, for range finding and a whole lot more.
Most people don't know where the idea of the laser came from. The idea for the laser came from a machine called a maser. The maser was a tool that was able to strengthen, or amplify radio and light waves. The first laser was made in California in 1960. It was built by Theodore Maiman along with a group of American scientists. The material they used for a concentrator was a man- made ruby. This was done by, coiling a simple flash tube around a rod, and beaming powerful flashes of light at it. The result was pulses of red laser light. Once they made the device they had to name it. They had think of some word or words to described it. They came up with Light Amplification by Stimulated Emission of Radiation. Using the first letter of each main word they named it laser. The laser had everyone excited.
The laser was put through many tests and experiments to see what it could do to help modern civilization. At first there weren't many uses for the laser. Then in the 1970's it became very important. It was finally being used in everyday life. As years went on the uses grew in number.
Today lasers were being used in a variety of ways. This includes entertainment, military, communication, businesses, measurement, cutting, and more.
Measurement: Lasers have become an important part of measurement. A laser is the fastest way to measure long distances. This use can be applied in construction work and astronomy.
Cutting: A laser is also great for cutting objects. It can get to those hard to reach places by the use of mirrors to bend the beam of light. It also is strong enough to cut through solid steel. A laser never damages the surface of the object because it never touches it. Lasers have been
used in both large and small surgical procedures. It is used by jewelers to cut diamonds, gold, silver, platinum, etc....It is also used in corporations in which cutting metal or fine cutting is involved.
Communication: The way the laser is used in the field of communication is through fiber optics.
It is the responsibility of whoever was hopeful first and spread that hope to the less hopeful. When the expectations of the hopeful individual are not reached, it is his responsibility to make the others accept the unwanted outcome.
In light of the most recent election results I find myself worrying about the countless social and economic injustices that will perpetuate to occur in our country. I dwell on our history, of how our social welfare system created and continues to reinforce discrimination, privilege and oppression. How did we end up like this and where is that “American dream” promised to those within our boarders? Literary works $2.00 a Day: Living on Almost Nothing in America by Kathryn Edin and Luke Shaefer, Nobody: Casualties of America’s War on the Vulnerable, from Ferguson to Flint and Beyond by Marc Lamont Hill, and Bryan Stevenson’s book, Just Mercy: A story of justice and redemption, seek to describe how social injustices and economic issues manifest
Racial representation in death row proves that justice system consistently shows bias, primarily through crime victim treatment. Though originally the Supreme Court
The University of a Florida offers meal plans for students who wish to have a meal ready for them rather than worrying about what they are going to eat, or perhaps cook, throughout the day. The problem with this idea however, is that students oftentimes do not take full advantage of this system. Whether it is cooking, eating out, or even going home on the weekends, there are several factors that can get in the way of taking full advantage of the meal plan. This dilemma often leaves families asking the same question: is buying the meal plan that is provided by colleges actually worth the money? While buying a meal plan for college appears to make sense for many incoming freshmen, it does not always translate into the most efficient use of their money.
These lasers can be used for such things as to reduce abnormal eye pressure, to treat glaucoma (an eye disorder), and to repair failed glaucoma surgeries. Holmium is also used for its ability as a magnet. For example, holmium may be used in a high strength magnet such as in a magnetic-flux concentrator to create a strong artificially generated magnetic field. It may also be used in the future since scientists are still learning more about this elements distinct magnetic properties. But, for now all we know about holmium is that it has no role biologically and that it is also not toxic. Scientists however have suspicions that holmium may stimulate
What does this mean? In the simplest way, BinOptics produces lasers. These tiny lasers, some the size of a grain of salt, transfer enormous amounts of information to another source immediately. The integrated laser chips are the key part of optical transceivers and transponders. BinOptics’ edge-emitting laser consists of a two-inch wafer that has 20,000 lasers on it.
Multiculturalism policy was first adopted in Canada in 1971, which reaffirms the dignity and value of all its citizens regardless of ethnic origins, race, religious affiliations, or language. Part of this policy, Canada confirms the rights of all the aboriginals along with the recognition of two official languages. Indeed, multiculturalism has great importance since its main purpose is to give equal treatment to all the citizens (Daniel, 2010). It ensures that all individual citizens could still maintain their identities, and have pride with their ancestry. Through this initiative, the Canadian government was able to give their citizens a feeling of self-confidence, making them more open to their diverse cultures. The multiculturalism policy
In conclusion, multiculturalism and immigration are vital factors in the evolution of Canada to be a strong multicultural example of economic stability, social, and political growth. They have lead to the emergence of Canada as a nation. The Government of Canada pioneered the Multiculturalism and Immigrant policy which help immigrants to keep their cultures and religions, while, learning new opportunities such as a better education system and training programs for children, teenagers, and adults, better translations and interpretations for immigrants who are seeking work, and strive to live in a harmonious and peaceful country.
Canada is an ethnically diverse country. The notion of "multiculturalism" began circulating in Canada in 1971 and is a word that is now commonly used to define this country, unlike the word "melting-pot" which is used to describe Americans' loss of ethnic identity. The broadcasting system in Canada is pressured by the government to acknowledge the culturally diverse society by broadcasting a fair representation of the population in terms of ethnicity. This is achieved through the many acts that have been passed through parliament: the multiculturalism policy of 1971, the Canadian Multiculturalism Act of 1988, the Canadian Charter of Rights and Freedoms of 1982, the Ethnic Broadcasting Policy of 1985, and most recent, the Broadcasting Act of 1991. These legislative and policy frameworks have provided guidelines for the management of Canadia...
Multiculturalism is a significant fabric of Canadian society that defines its unique identity among the rest of the world. Enactment of the Canadian multicultural policy (1971) affirmed government position and recognition of multiculturalism as a vital element of Canada. It is imperative to understand that multiculturalism is a static concept that keeps changing overtime and has a multidimensional entity. Canadians have always and will continue to revise the concept of multiculturalism to suit the ever expanding needs of Canadian society. In this paper, I will evaluate the reasons behind Canada’s adoption of multicultural policy and assess whether the policy should be maintained or not. I will defend the thesis that Canada’s multiculturalism
There are several principles outlined within the framework of CBT: thinking, cognitions and behavioral change. The concept of thinking is commonly confused with one’s emotions; in Cognitive Behavioral Therapy, one must first identify and differentiate their feelings from their thoughts. The feelings that are identified and shared may instead be thoughts and beliefs that are expressed in an emotional statement. Cognitions affect behavior and behavioral responses come from the process of rewarding or unrewarding consequences, indicating that cognitions can be changed and monitored. Lastly, behavioral change allows clients to focus on their misconceptions which can result in the realization that change may be
LIDAR, stands for Light Detection And Ranging, is an active optical remote sensing instrument. It is an innovative technique that uses laser for probing the planetary atmosphere [1, 2, and 3]. Atmospheric LIDARs use narrow pulsed lasers. Flash-lamp pumping is generally employed in generation of Q-switched lasers. Flash-lamp pumped (FLP) systems produce lasers at low repetition rate with high pulse energies. Several problems such as limited life-time of flash-lamp and requirement of pump motors for driving deionised (DI) water to cool the laser cavities limit the applications of FLP systems in strategic fields. Recent technologies employ semiconductor diodes as pump sources for solid-state lasing materials. These units built-in with accousto-optic modulator (AOM) produce pulse modulation in laser at high repetition rates. Diode pumped solid-state (DPSS) lasers offer several advantages over conventional FLP types. DPSS lasers generate radiations in Infrared (IR), visible and ultraviolet (UV) spectral bands. The commercially available DPSS lasers offer features as high pulse repetition rate, excellent beam profile, compact size, narrow pulsing, good spectral purity, long-life and stable output. Moreover, DPSS lasers operate with air cooling.
As you can see lasers are a very useful and important tool which is why I have
“Cooking gets a bad rap. People use the excuses: It’s time-consuming, inconvenient, or difficult. Who has hours to chop ingredients, monitor cooking times, and do all the other herculean work that preparing a meal can seemingly demand?”(Hyman) A lot of it depends on how a person thinks of cooking when it's time to do so. Yes, it’s very time consuming, inconvenient and difficult, but it all depends on what a person will cook. It doesn't have to be a gourmet ‘Gordon Ramsay’ styled meals every time, it can be something simple and fun. “Get everyone involved. Enlist help from family members — drag your kids away from their video games and ask them to measure ingredients, pull food from the fridge, or even chop veggies if they’re ready to take on this task. Decide on meals together to get everyone excited about what’s in
Cooking at home needs a significant plan. As a good planner, it is necessary to think earlier for preparing the food. It is necessary to make a list before going to grocery shopping. Cooking is not only to make a plan but also to control the quantity of food. If it is bought a lot; if shop not enough food, the food must to be finished earlier this week. People who cook at home are able to be an excellent planner. When there is lots of food in fridge, it will take space to set food into fridge and requires
