Impact of Leonardo Da Vincis Inventions

Impact of Leonardo Da Vincis Inventions Engineering Drawings To be a proficient engineer, it requires a person to develop and possess various skill sets. The understanding of the various concepts and knowledge presented to them is crucial as well as it would allow them to apply it to their work as a practicing engineer. Some engineers may consider their best tools to be a piece of paper and a pencil. Possessing the ability to graphically communicate their ideas by sketching or drawing them, allows some of these ideas to come to life. Best known for his paintings of the Last Supper and Mona Lisa, Leonardo Da Vinci was more than just an artist, he was also an inventor and to some he is considered to be the worlds most famous engineer. His fascination for knowledge and his ability to bring his ideas to life shows that he is the epitome of an engineer. Only at the age of fifteen is when Leonardo was progressing in advancing his artistic skills under his teacher, Andrea Del Verrocchio. By 1482, Leonardo had chosen to move to Milan, Italy from Flore nce (which at the time was considered to be a more militaristic city than Florence), to work for Duke Ludovico Sforza as a military engineer. From there, Leonardo was able to innovate the war machines used by the military at the time. He essentially paved the way for some of the common weapons used in the modern day military. One of his war machine inventions was called the 33-Barreled Organ. Leonardo got the idea for this weapon when he saw that a cannons shot may not be as accurate and took quite some time to reload in battle. He figured that if a soldier could reload the weapon and fire at the same time, it would prove to be much more effective in the battlefield. The guns design consisted of a wheelbarrow like structure with big wheels and attached to it in the middle were the thirty-three guns split into three rows, which meant eleven shots were possible with just one row. It also had a rotating wheel to allow one row to fire while the other was being prepared for the next round. Leonardos idea for this barreled gun was it is now seen as the machine gun in modern day military. Another military innovation from Leonardo was the Armored Car, also known as the military tank in modern times. Leonardo thought to himself that if the soldiers could get closer to the enemy frontlines as well as their artillery that meant no soldier could stop their attack and would be forced to scatter. The armored car featured multiple cannons around the vehicle, thus giving the soldiers inside a firing range of three-hundred and sixty degrees. The shape of the vehicle consisted of a cone with a view port for a soldier to direct the vehicles motion. However, it was discovered there was an issue within the vehicle that would not allow it to move in a forward motion. Some suggested that da Vinci might have sabotaged his own design to discourage the war machine from ever being built. (Leonardo da Vincis Armoured car invention, 2008). As Leonardo was developing other war machines, he had decided to take an existing idea and improve on it for use on the battlefield. He took the soldiers average crossbow and decided to create a giant version out of it. Leonardo had claimed that this weapon was the best way to terrify the enemy. The Giant Crossbow was measured to stretch as far as 27 yards across the field. It consisted of six wheels, three on each side, to ensure mobility during the battle. It also had to be made of thin wood to allow the crossbow to have some flexibility. But the issue was, where Leonardo would create large enough arrows for use in battle. Instead, the crossbow launched large pieces of stone and at times, flaming bombs. To launch the object, it required the soldier to wind back the bow and then use a mallet to push the pin out of place for the weapon to fire. Leonardo had also improved another commonly used weapon during the war. In his observations, he found that the cannons shot may not be accurate and was too slow to reload after each shot. This meant that if the shot missed, the soldiers would be lacking in damage. He also found that the cannon lacked sufficient mobility in the battle. He designed instead a faster and more lightweight version of the cannon. But it did not just consist of one cannon, it included three cannons. Due to how lightweight it was, it made mobility on the battlefield much easier for the soldier. This also meant that the soldier could fire multiple shots at once as well and at a much faster rate compared to its predecessor. Seventeen years later, Leonardos time as a military engineer under the rule of Ludovico Sforza had come to an end once the French had invaded Milan. This left Leonardo to pursue other projects and come up with new inventions while travelling to other cities. Leonardo ended up designing an invention known as the ornithopter or known as the flying machine. His inspiration for this machine came from birds and kites. He had hoped one day the average man could fly as high as them in the sky. He specifically studied how the birds would use their wings to fly and would apply the concept into his design. However, it would become quite more apparent that the design of the wings, resemble the wings of a bat. The wingspan of the ornithopter was beyond thirty three feet. The material he used in the design of the wings consisted of pine and raw silk. This allowed the wings to be light and allow it to be easily carried by the wind. He would then have the pilot sit in the center between the wings a nd push a pedal in an alternating fashion while the machine flapped its wings. But Leonardos interest in flying did not stop there, he had come up with another invention. This time, Leonardo came up with the Parachute, not specifically the one seen in modern day, but the early sketch of a parachute. His idea of the parachute would come from a tent made of linen, sewn together to make sure all its openings were not letting air through and it would have a wooden frame which allowed the person to attach some rope to it to be able hold on. He believed at the time, that this device would allow a person to be able to jump from nearly any height without injury. But, at the time there were not any extremely high up places that were viable enough to be used for testing. It was not until the year 2000, when a known daredevil by the name of Adrian Nicholas decided to try Leonardos design of the parachute. Critics doubted his design would work and would put Adrians life at risk. But after jumping from 3000 feet above ground, Adrian proved that Leonardos design was successf ul. He also discovered that the ride to be smoother than the ripcord parachute found in modern times. But, the weight of the parachute was a concern since it could potentially injure the user as they land. Near the end of the fifteenth century, Leonardo had come up with another invention that was seen once again as ahead of his time. Using gears, pulleys, and cables, he was able to create a robot knight. By taking a knights suit and fitting it with the gears, pulleys, and cables, he was able to give the suit the ability to move various parts such as the arms and legs using different pulley systems within the suit. It could also perform human like actions such as sitting down and standing up, moving its head, and opening its mouth piece. But since then, Leonardos full drawings could not be found together, but rather, scattered designs in his notebooks. However, in 2002 a NASA roboticist by the name of Mark Rosheim took Leonardos design and was able to create a prototype out of it. As he was building the prototype, he discovered how Leonardo designed the robot to be easily built. This truly showed how Leonardo was a man ahead of his time. This allowed people in modern times now to take i nspiration from Leonardos Robotic Knight and to apply similar concepts to what is created today. It would be quite challenging to imagine life without some of the designs that Leonardo Da Vinci had created which helped pave the way for some of the modern day inventions. One may question what the world would be like in terms of technological and architectural advances had people neglected his work or he chose to not share his ideas. One can come to the conclusion that Leonardo Da Vinci was more than just an artist, but he was also an innovator that was way ahead of his time. References ENGINEERING.COM. (2006, October 12).

Love Wasnt :: essays research papers fc

Love Wasn’t   Ã‚  Ã‚  Ã‚  Ã‚  Love is sacrifice of one’s self for the people you care about most in your life. Love is a choice to do what is best for another person. There are times when choosing to love someone comes at a great cost. You have to sacrifice something; time, money, energy, and sometimes the supreme cost will be giving up your own life so that someone else can live. When it really costs you something to carry on in a relationship or to help someone, that is the real test to find out if you truly love that person. If you bail out, you have just proved that you love yourself more than the person who needs your help. If you do what is best for the other person even though it is difficult for you, then you have discovered real love, a love that you choose to exercise regardless of how you feel. I feel like Louise loved him in the beginning of their relationship, however, over time she was only comfortable being with him. Staying together was easier than being alone. So when she found out about his death, and that it was not her fault, she could be free without taking any blame. According to Joseph Rosenblum, â€Å"nothing can compensate Louise for the freedom that she has lost by marrying. Her face â€Å"bespoke repression†; no matter how kind Brentley has been, he has still imposed his will upon his wife. Hence, Brentley’s death is not tragic to her, since it gives her own life back to her† (Rosenblum par 7) The story states that she had loved him some of the time, which I believe if not all the time, then love did not exist throughout most of their marriage. When Louise whispered free over and over, she exhibited the fact that her life would be lived without the constant controlling of her husband. I think that since being diagnosed with heart trouble, maybe Brently must have been a little forceful with Louise to make sure she would not get worse. He could have imposed rules that she must abide by in order to prevent her from getting worse, such as, staying in bed, confining her to the house, and keeping her from doing things she enjoyed doing. Her freedom could be doing all the things he would not allow. Rosenblum supports this freedom with this passage:

He produces information on students and for staff to help in teaching and learning, he also produces statistics for staff, senior staff, LEA and DFES. He also produces information to do with effort grades ad target setting information. So he uses a lot of technology, this includes; * PC’s on a Network * Apple Mac’s on a Network * Internet via 10MB broadband * E-mail * Laptop also on Network * Digital Video Camera * Digital Still Camera * Digital LCD Projector * Palm m515 PDA * Wireless Notebooks Window/MAC OS * USB Memory sticks * Data Logging Hardware * Control hardware/software * Fax * Also available – Interactive Whiteboard Mr Williams is a teacher of I.C.T and business studies at Key Stage 3, teacher of I.C.T at Key Stage 4, Production, collection and collation of Reports for the whole school, effort grades and target setting information he produces also. He produces of information on students for staff to use which will help in teaching and learning. He has achieved the Electronic registration system for the whole school within 12 months for people to use and view. He performs general backup for staff using RM software, he also performs General Network Administration which is adding new pupils and staff users. He gives advice on purchasing new equipment for the whole school and departments. He selects, purchases and setup’s laptops for teachers using E-Learning. Mr Williams analyses exam results so senior staff and heads of years or departments so they are aware of achievement compared to the expected results. Staff are also able to view these results so they can be aware of performance issues. Subject staffs, heads of years and departments, senior staff and form tutors are also able to access these results, grades and comments. Extra software is available which will help staff by using the system that was introduced by Mr Williams, (software produced using Microsoft Visual Basic). The RM Network The RM network system allows Mr Williams to access the information on students and is able to update it if needed such as if the student changes address or phone numbers. Mr Howells can now, after Mr Williams has set the network up, can get access to LEA Management Information System and the school records. Data bases are creates to hold student information on staffs users names or folders on their laptops. Mr Williams has also enabled access from home, using the internet and school passwords. He has also updates the Pupil Achievement Tracker software which allows staff to store progress of students within classes or year group. The RM connect system enables Mr Williams and two other members of staff, who are supervisor users, to access students work areas to solve problems and to check appropriate use of programmes and internet. The E-mail system is also filtered so inappropriate E-mails are redirected and staff are able to view them, the access of websites with inappropriate langua ge or content such as pictures, Mr Williams and the other two members can check. The RM system is set up to allows staff to open Read only documents so they can give students access to related subjects. Mr Williams uses this for providing information, revision materials, coursework guides and modelling situations and simulation materials. Also used is a Virtual CDROM software and a multimedia server this allows staff and students to access CDROM images, such as the Applied ICT On-Line course used in years 9, 10 and 11. Digital Multimedia Technology Mr Williams also uses digital multimedia technology to help provide teaching and learning resources. Mr Williams used a digital camcorder, a still camcorder and Video editing software on Apple computers on a programme called IMovie and Windows, Microsoft Movie Maker2 to interview staff in local company. The final video clips were used on Matchware Mediator, which helped him to produce a series of web pages which students now use for their coursework tasks. Digital LCD Projector Mr Williams uses a digital LCD projector to allow students to use and interact with progressing work. Either Mr Williams or a Student will control the PC being used in the demonstration or teaching session. Mr Williams also uses this technology with teachers on Inset days for staff. School Internet Network Mr Williams uses the internet the school provides for teaching and learning and links on the school system. The internet is used for research for topics and to help Mr Williams keep up to date with the education and subjects. Students and staff use the school e-mail system to communicate or send work for marking or that has been marked via E-mail. Mr Williams can view student’s progress on GCSE grades by using created databases in DataPower which stores coursework marks, comments and examination marks. Formulae is used to estimate the final grade the student may be given to the student, he can do this by using board supplied information. This information is shared with students and used to report back to parents. Virtual Learning Mr Williams has helped in the introduction of a Virtual Learning Environment (VLE). The VLE allows students to upload web pages to the school system and also as a secure data and information storage area for student’s work. PDA Mr Williams uses PDA in school; this holds a lot of useful information such as Diary information, pupil performance information, examples of E-book for future reference by students in the school. Software and information can be ‘beamed’ using Infra – Red technology to members of staff or to certain Infra-Red equipped printers in the school. USB Stick Mr Williams has introduced the use of USB stick technology which enables transport of large amounts of data in a compact secure form (32 or 128 Mb at present). Data Logging and Control Hardware Mr Williams uses Data Logging and Control hardware in teaching and provides INSET days for ICT and Science staff, these days are needed to improve the quality of teach Wireless Mr Williams uses the wireless (55Mb) notebooks with students in school and with adult learners to allow them to experience new technology. The advantages are obvious, a lot more space recommended for each machine, extra infra form is required, (Wireless access points can be plugged into network sockets, for easy movement), students can also work in groups in a more adjustable way. The School Network The School Network System enables Mr Williams to access information on students or necessary by students or staff anywhere in the school. Software He uses a lot of software such as Microsoft Word Access, Microsoft Excel, Microsoft PowerPoint, Microsoft Publisher, DataPower 2, Macromedia dreamweaver, Macromedia Fireworks, Macromedia Flash, Macromedia Freehand, Adobe Acrobat, Adobe Photoshop, Pupil Achievement Tracker (PAT), IMovie, Microsoft Movie Maker 2, QuickTime Pro, Microsoft Visual Basic, Internet Explorer, EasyMail and Outlook Express. Hardware and Network, Windows Desktop PC’s, Windows Laptop, Apple IBooks (wireless) Apple G4 desktops, Apple Network using MACOS Xserver, RM Connect network using 5 NT4 servers and a multimedia server, Fibre Optic spine connecting four cabinets which contain Hubs and Switches, 100Mb Ethernet to the desktop, 10Mb Broadband Internet access with RM SmartCache technology, Palm m515 PDA using IR and USB technologies for transferring data. He also uses a Promethean Interactive Whiteboard, Sony digital video camera, Canon digital video camera, Sony digital still camera, Canon digital still camera. The Internet Mr Williams uses the internet for research, if he did not have the internet he would have to get information from textbooks, and use more textbooks during lessons while he teaches. If he had to do this it would be expensive. If he was not able to have access to the internet it would mean he would have to photocopy from books so he would have to arrange time before and after lessons to photocopy the information needed. To do this more money is needed to be spent and more time would be needed, so other jobs will not be able to be completed as time would be wasted on photocopying. As Mr Williams will always be up to date with resources as he uses the internet. Mr Williams also uses the internet to buy gifts for friends and family, such as buying tickets fro the cinema or theatre, with his friends and family. He likes using the internet to but gifts as he gets an online discount, that isn’t available in the shops and by using the internet he doesn’t have to waste time waiti ng in queues. Although there is a disadvantage about purchasing online as he doesn’t always get to see all the objects in the shop, and he also has to pay for delivery, but that works out the same as the amount of money he would of spent driving to the shop and parking. The PDA The PDA had several facilities this means Mr Williams will have all the information he needs for the day. If he didn’t have this piece of technology Mr Williams wouldn’t be able to travel around school to see students and teachers as he would have to carry lot’s of papers with him if he didn’t have this technology. Sometimes he is not able to take his laptop into meetings but with this programme he is able to save work to his area, this is handy as he will never loose his work or information, like he would if he had to carry paper around with him. The PDA has facilities which a useful to Mr Williams, such as alarms and a diary, this meets his needs as he is never late to an appointment or meeting and never misses a private party or function, like a family member’s of friends birthday party. Digital Camcorder He uses a digital camcorder to create applications for his students ICT classes. This allows Mr Williams to download the resources directly to the system. Mr Williams can now uses student friendly resources in his teaching schedules, enriching and improving the experience of his students education. Memory Stick Mr Williams uses a memory stick which allows him to be more resourceful and more flexible in his job. This means Mr Williams can hold data on and be able to transport it around school easily. As he can store more work it means he can do more work at home in his own time in the evenings and at the weekend. This means Mr Williams can now spend more time at home as before he had a memory stick he would have had to spend more time at school, which before he felt he was missing out on his family life. Notebook Dell D810 He uses a Notebook Dell D810, this means he now has more freedom than he used too. Before he had this laptop it meant that he had to sit at a desktop, which is usually in a classroom, and could not get much work finished. This programme means that he can move around during school, as long as it has a wireless connection to the network, having this means he can complete all of his work. Microsoft Word This Microsoft programme can give Mr Williams a variety of options and facilities. One of the facilities is mail merge is useful for producing reports for students. If Mr Williams did not have this option of using Microsoft Word, it would take him an awful long time to add address’s and reports for students. The word processing software also checks his spelling and grammar so it looks professional and correct. Power Point is also used by Mr Williams to create presentations for students. Having this programme allows students how to create different fun pieces or work. E-Mail Mr Williams uses E-mail for school and his social life he uses this so he can send work to and from home, also he can sends work to students via e-mail, with suggestions on how to improve their work. He also uses this to communicate with his family and friends to arrange events in his social life. He likes e-mail because he knows that when he sent an e-mail, it will be viewed by the person he has sent it to, when they open their inbox. This therefore means he can communicate. This means he can communicate with anyone when he is on his computer and isn’t near a phone. Doing this means he doesn’t have to wait until the person turns on their phone or leaves a message or is at home. Mr Williams feels that when he leaves a message on a phone, he doesn’t feel he can communicate properly. He knows that if he sends an e-mail, all of the necessary information will be displayed once read. Network System Mr Williams is able to access information anywhere in the school. This means that he can complete his work anywhere and any time, when he has spare time.

The Silent Struggle For Well Water Users - 1865 Words

The Silent Struggle for Well Water Users Located in a small town of Licking county lays Brownsville. A town with less than 150 homes and no more than 300 people. While everything seems to be normal on the outside of the home, the inside is the quiet struggle of many people living in this town. Brownsville has well water that destroys many household items, including but not limited to, utilities, dishware, and clothes. While not all Well water is bad, Brownsville has water that has a fifteen iron count level, which is higher than normal. Well water in Brownsville Ohio is an issue that needs to be addressed and there are many solutions to the problem but the best solution is purchasing a Kinetico Water System. Evidence Figure one: Figure†¦show more content†¦Although residents do not have to pay for Well water, the price does not come free when items of the home need replaced. As the home owner, the family purchases five gallons of water at a one dollar a piece, throughout the week for meal preparation and drinking. This totals to $260.00 at the end of the year. Money is also spent on replacing clothes for the family of five that have stained orange, and in the future, will need to be spent on replacing household cooking utensils and pots; as well as the shower, toilet and kitchen sink. Past Attempts for Resolution Previous attempts have been made to fix this issue. The previous home owner had installed a new Kenmore water softener, in which the owners had to continue to add three 15lb bags of Morton salt to clear up the iron that was going through the system. This brand of water system costs up to 600 dollars and once every two weeks had to have new salt put in, which costs fifteen dollars a bag. This put the home owner spending 90 dollars a month on salt, which turned into 1,080 dollars in a year. Because Brownsville has such hard, salt filled water and was an electric unit, the Kenmore system broke after a year. This leads into discussion of one of a few options that home owners can have. Option One: Kinetico Home Water System In order to have a good working water system that works for this hard water, homeowners in Brownsville could purchase the Kinetico home water system.
