How Eli Whitney Invented the Cottin Gin

How Eli Whitney Invented the Cottin Gin Eli Whitney was the inventor of the cotton gin and a pioneer in the mass production of cotton. Whitney was born in Westboro, Massachusetts on December 8, 1765, and died on January 8, 1825. He graduated from Yale College in 1792. By April 1793, Whitney had designed and constructed the cotton gin, a machine that automated the separation of cottonseed from the short-staple cotton fiber. Advantages of Eli Whitneys Cotton Gin Eli Whitneys invention of the cotton gin revolutionized the cotton industry in the United States. Prior to his invention, farming cotton required hundreds of man-hours to separate the cottonseed from the raw cotton fibers. Simple seed-removing devices have been around for centuries, however, Eli Whitneys invention automated the seed separation process. His machine could generate up to fifty pounds of cleaned cotton daily, making cotton production profitable for the southern states. Eli Whitney Business Woes Eli Whitney failed to profit from his invention because limitations of his machine appeared and his 1794 patent for the cotton gin could not be upheld in court until 1807. Whitney could not stop others from copying and selling his cotton gin design. Eli Whitney and his business partner Phineas Miller had decided to get into the ginning business themselves. They manufactured as many cotton gins as possible and installed them throughout Georgia and the southern states. They charged farmers an unusual fee for doing the ginning for them, two-fifths of the profits paid in cotton itself. Copies of the Cotton Gin And here, all their troubles began. Farmers throughout Georgia resented having to go to Eli Whitneys cotton gins where they had to pay what they regarded as an exorbitant tax. Instead planters began making their own versions of Eli Whitneys gin and claiming they were new inventions. Phineas Miller brought costly suits against the owners of these pirated versions but because of a loophole in the wording of the 1793 patent act, they were unable to win any suits until 1800, when the law was changed. Struggling to make a profit and mired in legal battles, the partners finally agreed to license gins at a reasonable price. In 1802, South Carolina agreed to purchase Eli Whitneys patent right for $50,000 but delayed in paying it. The partners also arranged to sell the patent rights to North Carolina and Tennessee. By the time even the Georgia courts recognized the wrongs done to Eli Whitney, only one year of his patent remained. In 1808 and again in 1812 he humbly petitioned Congress for a renewal of his patent. Eli Whitney - Other inventions In 1798, Eli Whitney invented a way to manufacture muskets by machine so that the parts were interchangeable. Ironically, it was as a manufacturer of muskets that Whitney finally became rich. The cotton gin is a device for removing the seeds from cotton fiber. Simple devices for that purpose have been around for centuries, an East Indian machine called a charka was used to separate the seeds from the lint when the fiber was pulled through a set of rollers. The charka was designed to work with long-staple cotton, but American cotton is a short-staple cotton. The cottonseed in Colonial America was removed by hand, usually the work of slaves. Eli Whitneys Cotton Gin Eli Whitneys machine was the first to clean short-staple cotton. His cotton engine consisted of spiked teeth mounted on a boxed revolving cylinder which, when turned by a crank, pulled the cotton fiber through small slotted openings so as to separate the seeds from the lint a rotating brush, operated via a belt and pulleys, removed the fibrous lint from the projecting spikes. The gins later became horse-drawn and water-powered gins and cotton production increased, along with lowered costs. Cotton soon became the number one selling textile. Demand For Cotton Grows After the invention of the cotton gin, the yield of raw cotton doubled each decade after 1800. Demand was fueled by other inventions of the Industrial Revolution, such as the machines to spin and weave it and the steamboat to transport it. By mid-century America was growing three-quarters of the worlds supply of cotton, most of it shipped to England or New England where it was manufactured into cloth. During this time tobacco fell in value, rice exports at best stayed steady, and sugar began to thrive, but only in Louisiana. At mid-century the South provided three-fifths of Americas exports, most of it in cotton. Modern Cotton Gins More recently devices for removing trash, drying, moisturizing, fractioning fiber, sorting, cleaning, and baling in 218-kg (480-lb) bundles have been added to modern cotton gins. Using electric power and air-blast or suction techniques, highly automated gins can produce 14 metric tons (15 U.S. tons) of cleaned cotton an hour.

The sucess of women in engineering programs Essay

The sucess of women in engineering programs - Essay Example Upon the arrival to higher education the female students are recruited and enrolled in the engineering field. There are several established mentoring programs that are offered to the female students so that they start well, maintain the interest, maintain a high Grade Point Average (GPA), remain in the engineering field, graduate successfully from their undergraduate programs, and pursue graduate work in engineering and/or work as engineers. WEPAN (2005) also recognizes the achievements made by women engineers, such as honoring them with The Betty Vetter Award for Research. There are professional organizations and advocate groups (WEPAN, 2005) that offer workshops, lectures, and seminars geared toward the female engineers. This serves as a support system to help them become interested in engineering, maintain them in engineering, and help them become female engineer leaders. They are also given awards in recognition of their active participation in research related topics to women in engineering (WEPAN, 2005). Female engineers are given a variety of tools to support them in their endeavors of becoming and staying in the engineering fields as successful engineers. WEPAN (2005) also has The Women in Engineering Initiative (WIEI) Award that gives recognition to outstanding programs or projects to serve as a model to other institutions. Their selection criteria is that: it serves as a model, shares experiences and materials with other institutions; serves as a model for programming formal pre-college or retention activities/projects; shows improvements in education for women in engineering; and, provides professional guidance to students and/or faculty seeking engineering and science as a career or profession. The Student Outreach Program – Evaluation Tools AWE – Assessing Women in Engineering Project develops assessment instruments and models; assesses program activities to achieve success in the recruiting of women

Iconic building, building underground Essay Example | Topics and Well Written Essays - 1500 words

Iconic building, building underground - Essay Example The debates mainly covered topics such as: One of the proposed solutions to future attacks is the underground construction of buildings. For example, there have been proposals to expand the city of Amsterdam with a futuristic and massive underground network of activities. This paper seeks to examine the construction lessons learned from the WTC attacks and the possibility of considering underground construction as a way of avoiding attacks situations similar to the one of the WTC. The twin towers were designed and constructed five decades ago as new way of building skyscrapers in which they were to be very light in weight and involved modular methods of construction meant to reduce costs and accelerate the building schedule. They were constructed using an egg-crate design having extra columns that would hold the building standing in case one or two columns were to be lost (Eager & Musso, 2001). This design made the towers to be some of the most resilient buildings ever constructed and it is no wonder their collapse was that astonishing and generated so much speculations and debates among knowledgeable structural engineers (FEMA, 2002; National Institute of Science and Technology, 2008)). Prior to the WTC attacks, security in design was not all that an important concern to engineers, architects or builders (Bazant and Cedolin, 1991). Security was normally only considered a design priority when designing and constructing specific types of projects such as consulates, government facilities and prisons and State Department embassies. Following the attacks, security has become of absolute importance in virtually all types of construction including educational, healthcare, commercial, residential and institutional. The drastic change in the construction environment, which occurred virtually overnight, makes it important that all suitable technology and security safeguards are incorporated into the initial

Successful andor unsuccessful application of organizational behavior Essay

Successful andor unsuccessful application of organizational behavior concepts in any organization - Essay Example Concepts that are inevitably connected with organizational behavior are those which have a direct impact on the above corporate objectives of the organization. The most common among these concepts are the organizational culture, effectiveness, diversity, learning, efficiency and communication. Wal-Mart has been well known for its unique Human Resource Management (HRM) practices, extremely democratic organizational structure/culture and highly successful employee motivation strategies. Organizational culture consists of both the individual and collective characteristics of the employees within the organization. "Organizational culture is a pattern of knowledge, belief, and behaviorit is the form, beliefs, norms, social patterns, the way things are done, the symbols and rituals" (Burton, Lauridsen, & Obel, 2004). Organizational behavior and its associated concepts of Wal-Mart have to be examined against its HRM practices, organizational structure and employee motivation strategies which in turn depend on other variables such as the impact of globalization on the business, government rules and regulations, market demand for and supply of factors of production such as labor and the level of competition. The geographical and occupational mobility of labor also matters. Wal-Mart with a workforce of roughly 2.1 million is the biggest public company in the world by revenue, i.e. US $400 billion (approximately) in 2008. These staggering figures apart the giant grocery retailer has been looked upon as the model American business organization by many analysts and industry experts.Theoretical underpinnings about organizational behavior and the related concepts have been evolving over the years from Taylor's scientific management theory, through human relations theories and theory X and theory Y people to the modern day behavioral theories. This historical delineation signifies a number of aspects about the conceptualization of organizational behavior in the modern business context. Thus a particularly important aspect of leadership research in the sphere of organizational behavior is focused on Social Identity Model of Organizational Leadership (SIMOL). SIMOL is currently in vogue for the sole reason that it serves not only as a behavioral approach to organizational culture but also as a contingency model to study leadership (Kramer and Staw, Editors, 2003, p.283). Its relevance to this analysis lies in the correlation between the organizational behavior concepts such as organizational communication and diversity and corporate objectives such as profits and market share.Next theoretical postulate which has a significant bearing on organizational behavior concepts is the leadership style and the latter with a considerable amount of complexity applies to a variety of business cont exts. For instance leadership style in Wal-Mart is characterized by a degree of democratic delegation of freedom to the staff to take decisions at the operational level. This aspect of the organization is subject to critical analysis for it obviously presumes that organizational behavior engenders a series of culture-centric responses to the external strategic environment including that of competitors' behavior. Corporate strategy in this particular context plays

Analysis of Windows Operating System and Microsoft

Analysis of Windows Operating System and Microsoft What is Windows? Windows is a personal computer operating system from Microsoft that, together with some commonly used business applications such as Microsoft PowerPoint, Word and Excel, has become a de facto standard for individual users in most corporations as well as in most homes. It provides a graphical user interface (GUI), virtual memory management, multitasking, and support for many peripheral devices. According to OneStat.com, as of August, 2006, Windows as a whole dominates the personal computer world, running on about 97% of the operating system market share, with XP accounting for about 87% of that. In comparison Mac OS has about 2% and Linux (with all distributions) about .36% The reason why this is so is mainly because Windows is much more user friendly and everything comes pre-packaged so user just have to run the application and follow instructions for it to install. There are many versions of Windows Operating System available namely: Windows 286 Windows 386 Windows 3.0 and 3.11 Windows 95 Windows 98 Windows NT Windows 2000 Windows CE for use in small mobile computers Windows Me Windows XP Windows Vista Windows 7 Among all those versions, Windows XP is the most popular one and it is used by 61.9 percent of Internet users, according to data from Net Applications, followed by Windows 7 which has 14.46 percent of users and Vista -14.34 percent. A Brief Story On Windows Windows mainly concentrated on providing an operating system which was user-friendly, stable and less prone to crashes when they were implementing earlier versions. Now, even though XP is generally referred to being stable and efficient compared to other copies of Windows, it is still critised for being overly susceptible to security risks. Therefore the successor of XP- Vista, released in January of 2007 was designed in such a way so as it provides more security. The transition time between Vista and XP is the longest one between versions of windows. Vulnerabilities Of Windows What is vulnerability? â€Å"It is a weakness that makes a threat possible. â€Å" These vulnerabilities are used by attackers who exploits them to convey multiple attack, including enticing the users to open harmful and malicious media or to visit website which has a lot of viruses. These can have a lot of consequences. In the worst case, a hacker or attacker can get full access to the computer. Fortunately, windows provide a lot of solution to these vulnerabilities. The user just has to install the appropriate Microsoft patches or they are sometimes installed automatically with the help of Windows Update. Window Update Vulnerabilities can be compared to holes. They are like holes in the system. Windows periodically releases security patches mostly as Window Updates to fix those defects. There exists different level of security known as the â€Å"security level system† in Windows which describes the different levels of security holes: A critical security hole is â€Å"a vulnerability whose exploitation could allow the propagation of an Internet worm without user action.† An important hole is â€Å" A vulnerability whoses exploitation could result in compromise of the confidentiality, integrity, or availability of users data, or of the integrity or availability of processing recources.† A moderate security rating signifies that â€Å"Exploitability could result is mitigated to a significant degree by factors such as default configuration, auditing or difficulty of exploitation. And a low hole is â€Å"A vulnerability whose exploitation is extremely difficult or whose impact is minimal.† Source: Windows XP all-in-one desk reference for dummies Below is a list of Vulnerabilities in Windows MS10-033: Two Media Decompression Code Execution Vulnerabilities Description: It involves vulnerabilities in Media Decompression. â€Å"Windows ships with various components that help it process and play media files, such as videos. According to Microsoft, these media handling components suffer from two unspecified code execution vulnerabilities, involving the way they handle compressed data within specially crafted media. â€Å" Potential effect on system: An attacker can exploit these vulnerabilities by encouraging user to open specially crafted media file, download and install harmful software, by luring them to a website containing such media or by receiving specially crafted streaming content from a web site or any application that delivers Web content. In doing so, an attacker can exploit these vulnerabilities to gain the same user rights as the local user. If this happens, then the attacker will gain the complete control of that PC. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights. Microsoft rating: Critical. Solution: MS10-033. Since media files are most often the common targets of exploitation by attackers due to the increased potential for circulation via social group and the fact that it has been publicly been disclosed, it is estimated that the possibility that malware authors will look to exploit these types of vulnerabilities are high and hence, update must be installed. Targeted Software: Windows 2000 Service Pack 4 Windows Server 2003 Service Pack 2 Windows Server 2003 x64 Edition Service Pack 2 Windows Server 2003 Itanium based Systems No Pack Service Pack 2 Windows XP Service Pack 2 and 3 Professional x64 Edition Service Pack 2 Windows Server 2008 No Service Pack Service Pack 2 Windows Server 2008 x64 Edition No Service Pack Service Pack 2 Windows Server 2008 for Itanium Based Systems No Pack Service Pack 2 Windows Vista Service Pack 1 2 Windows Vista x64 Edition Service Pack 1 2 MS10-034: Cumulative ActiveX Kill Bit Update Description:â€Å"ActiveX controls are small programs or animations that are downloaded or embedded in web pages which will typically enhance functionality and user experience. Many web design and development tools have built ActiveX support into their products, allowing developers to both create and make use of ActiveX controls in their programs. There are more than 1,000 existing ActiveX controls available for use today.† Source: http://msisac.cisecurity.org/advisories/2010/2010-043.cfm Potential effect on system: There are several Microsoft and third party ActiveX controls which particularly suffer from various security vulnerabilities, found by Microsoft and other external researchers. This vulnerability allows remote code execution if a user views malicious website that has an ActiveX control with Internet Explorer. An attacker could exploit any ActiveX controls to execute code on the users computer, with that users privileges. If user has administrative privileges, the attacker will gain full access to the users pc. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights. Microsoft rating: Critical. Solution: MS10-008 This updates protects the pc by activating the Kill bit for every vulnerable ActiveX controls, they are this disabled in Windows. Microsoft Internet Explorer provides security feature which will prevent an ActiveX control from being downloaded without the users permission.

In Windows, access to the kernel is provided via the Windows kernel-mode device driver (Win32k.sys). Win32k.sys suffers from three elevation of privilege (EoP) vulnerabilities†.† The flaws are caused due to the way windows kernel-mode driver, improperly allocate memory when copying data from user mode frees objects that are no longer in use manage kernel-mode driver objects validate input passed from user mode. â€Å" Potential effect on system: â€Å"By running a specially crafted program on one of your Windows computers, an attacker can leverage any of these flaws to gain complete control of that system, regardless of his original user privileges. However, the attacker needs to have local access to one of your computers in order to run a malicious program. So these vulnerabilities primarily pose an internal risk.† Microsoft rating: Important. Solution: MS10-032 MS10-041: .NET Framework Data Tampering Vulnerability Description: â€Å"The .NET Framework is software framework used by developers to create new Windows and web applications. Among other things, the .NET framework includes capabilities to handle cryptographically signed XML content, to ensure unauthorized attackers cant alter XML messages being sent to your application. Unfortunately, the .NET framework doesnt implement XML signature checking properly. As a result, attackers could potentially send maliciously altered XML messages to applications youve created with the .NET framework† Potential Effect on system: The impact of this vulnerability differs greatly depending on the application youve designed, and what type of data you passed in your XML. If user havent been exposed to any web applications that rely on signed XML, then the flaw doesnt affect him at all. Microsoft rating: Important. Targeted Software: Microsoft .NET Framework 1.1 Service Pack 1 Microsoft .NET Framework 1.0 Service Pack 3 Microsoft .NET Framework 2.0 Service Pack 1 2 Microsoft .NET Framework 3.5 Microsoft .NET Framework 3.5 Service Pack 1 Microsoft .NET Framework 3.5.1 MS10-037: OpenType Compact Font Format (CFF) Driver Privilege Elevation Vulnerability Description: This vulnerability mainly occur when a driver that helps to display the OpenType CFF font, does not validate certain data passed from user space to kernel space. Moreover the driver can grant complete control of the affected system to any user who is logged in and is executing code. Potential effect on system: â€Å"By running a specially crafted program on one of your Windows computers, an attacker can exploit this flaw to gain complete control of that system, regardless of the attackers original user privileges. However, the attacker needs to have local access to one of your computers in order to run his malicious program. So this vulnerability primarily poses an internal risk.† Microsoft rating: Critical.

This list keeps on increasing with time, and fortunately Microsoft provides update so as to overcome these problems. Source: http://www.newagedev.net/2010/06/five-vulnerabilities-in-windows-and-its-components-two-critical/ http://www.sophos.com/ Threats Attacks There are many types of threats and attacks that Windows has to face. Also the fact that Windows operating system are most common among computer users, they are thus the more targeted by attackers. Threat V/S Attack What is a threat? â€Å"A potential occurrence malicious or otherwise that may harm an asset† What is an attack? â€Å"An action taken to harm an asset† From the two definitions above, we can say that a threat is more the possibility of doing harm to the Windows system, while attack is mainly the action taken to violate security settings. Types of Threats Attacks Below is a list of threats and attacks that are most common which can affect your Window Operating Systems. Types Of Threats Description Countermeasures Spoofing It mainly deals entering a system by stealing the identity of an authorised user. Example: Using the password and username of a person to enter his account and make changes without his permission. Do not keep password at the reach of other person. (for example in a plain text) Use spyware such as Spybot SD â€Å"Protect authentication cookies with Secure Sockets Layer (SSL).† â€Å"Do not pass credentials in plaintext over the wire.† Use strong and long password which is not easy to guess. Repudiation It involves the denial of participation in a communication which has occurred or denying that information has been received. Make use of digital signatures. Create secure audit trails. Tampering with data It mainly involves changing data manually to generate unexpected result. Example: Changing data on a web site. â€Å"Use data hashing and signing. Use digital signatures. Use strong authorization. Use tamper-resistant protocols across communication links. Secure communication links with protocols that provide message integrity.† Denial of service Prevent legitimate user from accessing a network or compuer by saturating it with requests. â€Å"Use resource and bandwidth throttling techniques. Validate and filter input.† Use software available on the net such as Radwares APSolute OS Information Disclosure It mainly involves making confidential information accessible to public or a group of unauthorised person. Encrypt file where information is stored. Keep back-up in secure places and use strong authorisations. Use passwords to be able to gain access to these information Use secure network when sending information. Malware (malicious Programs) It consists of any program that is installed either with or without permission of user, and whose aim is to cause harm to users pc by either gaining partial or full access to the system. Its impact can vary from slight as changing a folders name to full control of your machine without the ability for the user to easily find out. Types of Malicious Programs: computer viruses worms Trojan horses spyware Harmful adware scareware, crimeware, Most rootkits, and other malicious and unwanted software or program. Computer Viruses They are programs designed to cause harm to our computer system or the applications on the software. They are often attached to files which appear to be harmless to the operating system, but as soon as it is installed, the computer will operate different. There are viruses which even manage to close your computer without your permission. Types of Computer Viruses: * Boot sector computer viruses These types of viruses mainly affect the boot sector of the computer which is mainly in the bootable disk or in particular location in user computer hard drive. The boot sector viruses mainly affected the windows 2000 and examples of such viruses are: Disk Killer and Michelangelo. * Email viruses Emails viruses are transmitted through email as it name suggest. Normally they can be found as attachment and as soon as they are opened the computer gets the virus. Some may even replicate by themselves by forwarding themselves to all the e-mail addresses in the users address book. This type of virus is spread very quickly. Even though most of the mail system provides users with scan, a precaution one can take is opening mail from known-people only. * Companion viruses Companion viruses mainly affect a computers MS-DOS system. They create dangerous program that appears to be like the other normal files that are found on the computer. When a wrong command is enter into the prompt of the computer, it may end up executing the virus instead of the program that initially wanted to run. Fortunately, Windows like XP prevent such viruses from installing into computer as they do not require to use the MS-Dos command prompt. Worms Worms have the characteristic of self-replicating itself and they are thus spread very quickly. They exploit vulnerability on operating system and provide a gateway for other malware such as Trojan horse. An example of a worm which caused a lot of harm to mainly Window Operating system is: the ILOVEYOU virus. According to an article on WordPressTidBits For the Rest Of Us(WPTidBits), the ILOVEYOU worm (a.k.a. VBS/Loveletter and Love Bug worm), is a computer worm written in VBScript and it is considered by many as the most damaging worm ever. It started in the Philippines on May 4, 2000, and spread across the world in one day (traveling from Hong-Kong to Europe to the United States), infecting 10 percent of all computers connected to the Internet and causing about $5.5 billion in damage. Most of the â€Å"damage† was the labor of getting rid of the virus. The worm arrived in e-mail boxes with the simple subject of â€Å"ILOVEYOU† and an attachment â€Å"LOVE-LETTER-FOR-YOU.TXT.vbs†. The Pentagon, CIA, and the British Parliament had to shut down their e-mail systems to get rid of the worm, as did most large corporations. The worm overwrote important files, as well as music, multimedia and more, with a copy of itself. It also sent the worm to everyone on a users contact list. This particular worm only affected computers running the Microsoft Windows operating system. While any computer accessing e-mail could receive an â€Å"ILOVEYOU† e-mail, only Microsoft Windows systems would be infected. The worm propagates by sending out copies of itself to all entries in the Microsoft Outlook address book. It also has an additional component, in which it will download and execute an infected program called variously â€Å"WIN-BUGSFIX.EXE† or â€Å"Microsoftv25.exe†. This is a password-stealing program which will e-mail cached passwords. Trojan horse It is a malware which is difficult to detect, since it masquerades itself into files which appear to be normal. It can be on the computer without doing anything, and finally one day it can be the reason why your operating system has crashed. Unlike viruses, Trojan horses do not replicate themselves but they can be just as destructive. One of the most insidious types of Trojan horse is a program that claims to rid your computer of viruses but instead introduces viruses onto your computer. Spyware Spyware normally a tool used by companies to record web surfing habits Spyware is also known as the Advertising Supported software. They normally do not do any harm to the operating system as such, but they transmit personal identifiable information from a computer to some place in the internet without the permission of the user. Harmful adware â€Å"Adwareis the common name used to describe software that is given to the user with advertisements embedded in the application† They usually run advertisement or downloads posters without the permission of the user which often cause problem. Scareware Scareware are usually software used for marketing but which has unethical marketing tactics. For example, software which scans the computer and informs user that his computer is infected, and the later will have to download the following antivirus to be able to remove them. Hence, as its name says â€Å"scare† ware is a software designed to scare people by providing them with inexact information so as to promote a particular software/applications. Crimeware Crimeware consists of an application or a program which helps people to perform illegal activities. For example, software to hack windows live messenger password. They normally steal personal information about user of an account. Rootkit â€Å"It enables an attacker to have root access to the computer, which means it runs at the lowest level of the machine. A rootkit typically intercepts common API calls. For example, it can intercept requests to a file manager such as Explorer and cause it to keep certain files hidden from display, even reporting false file counts and sizes to the user. Rootkits came from the UNIX world and started out as a set of altered utilities such as the Is command, which is used to list file names in the directory (folder).† Source: http://www.pcmag.com/encyclopedia_term/0,2542,t=root+kiti=55733,00.asp Rootkits are normally inserted by the intruder so that he can again have access to it a later stage. Rather than just being a piece of code, it is a system of many linked programs designed to take control of a machine at the administrator level, and remain hidden to the systems users or legitimate administrators.

Comparing Frankenstein, Origin of the Species and Decent of Man Essay

Comparing Frankenstein, Origin of the Species and Decent of Man  Ã‚   I will demonstrate in this paper how Mary Shelley's Frankenstein confirms, and at the same time contradicts Darwin's ideas presented in "The Origin of the Species" and "The Decent of Man." Mary Shelley's Frankenstein is at once, confirming, and contradictory of Charles Darwin's scientific discoveries and views on science, nature and the relation of the individual to society. Mary Shelley confirms Darwin's ideas through Frankenstein, when Dr. Frankenstein and Darwin both reject God as the creator of human life. Although this is a major theme in both works, it is the only similar idea shared between both Darwin and Frankenstein. Darwin's understanding of nature is comparable to that of Mary Shelley; although how the individual relates to society is gravely different between the two works. One of Darwin's admiring disciples, Andrew Carnegie, the author of "The Gospel of Wealth," shows us how contradictory these ideas are in relation to each other. His ideas of inheritance and the conduct of man are in disagreement with the actions of Shelley's Dr. Frankenstein. Throughout Darwin's works the idea of the rejection of God as creator of man prevails. He alludes to prehistoric marine Ascidian larvae, as the predecessors to the later evolved human beings we are today. This would give credit for the creation of man to the process of evolution, not to the handiwork of a Supreme Being. "Species had not been independently created, but had descended, like varieties, from other species"(Appleman, 36). Darwin is showing here what conclusions he came upon about the "Origin of the Species", in which he used science to prove his theories. He is replacing God with ideas... ...heir works, giving the power of creation to evolution and mankind. They also both present similar views on nature, seeing it as a tool for scientific exploration and not as a wonder of beauty as it is often seen today. Using the work of Andrew Carnegie to show Darwinian ideas about the individual in society, we can see that these ideas strongly contradict those which Shelley presents in Frankenstein. Overall I believe that Mary Shelley's Frankenstein exemplifies many ideas expressed in the works of Darwin, enough that they can be considered enriching of each other in terms of comparison.
