An Overview of the Maker Movement â⬠What is It, and Why Now [Part 2] Hult Blog
ââ¬Å"I do not think that there is any thrill that can go through the human heart like that felt by the inventor as he sees some creation of his brain unfolding to successâ⬠¦such emotions make a man forget food, sleep, friends, love, everything.â⬠ââ¬â Nikolai Tesla In part one of theà Maker Movement overview, we took a close look at the first driver of the movement, access to global markets. Now, letââ¬â¢s take a look at the remaining three, as we begin to break down why the movement has become a global business phenomena. 2. Proliferation of cheap, powerful, easy to use tools For people designing physical products, the prices of the tools of the trade have fallen profoundly. When I was an engineering student (back in the day), 3D CAD software was priced as high as $50K per license. Today, open source 3D CAD software is freely available. Companies like Autodesk have made their software very affordable for micro-entrepreneurs and engineer-designers, but itââ¬â¢s not the only. GrabCAD enables mechanical system designers to source 3D models of key components that serve as the foundation of their systems, all from a global community of designers. What does this mean exactly? It means that engineers can tap into a network of fellow designers in order to build their products faster than ever before. Until now, software had been one of the largest barriers to using 3D printers. That is no longer the case. Designers can use Adobeà software toà design 3D models, and then send them to a local 3D printerââ¬âor an online 3D printer with outsourcing capability. Recently, the company announced that it will also integrate 3D printing inà Photoshop CC. In my day, 3D printers cost many hundreds of thousands to over a million dollars, limiting their use to a select few. Just a few years ago, 3D printers became mainstream (you can now buy one at Staples). And this year, on the exhibit floor of the International Consumer Electronics Show in Las Vegas, for the first time ever, a section of the exhibit hall was entirely dedicated to 3D printers. Leading 3D printer producers include open system pioneer MakerBot, now part of Statasys, and 3D Systems and RoBo3D. Or, perhaps thereââ¬â¢s something you want to scan before printing? Matterform has created a 3D scanner, making it easy to replicate objects by scanning and printing them. But designers, engineers, and makers of all kind donââ¬â¢t need a printer if they donââ¬â¢t really want one. Companies like CloudFabà allow makers to upload their designs into the cloud, which links them to an ecosystem of hundreds of global 3D printing companies that specialize in a wide range of products and materials. Designers can choose the company through which theyd like to print by searching for their ideal vendor mix of experience and quality.à à Some ventures offer more than just tools. Shapeways ââ¬Å"helps make and sell things,â⬠from really small items (think a ring), to larger ones (try a chair), with more than 30 material options. The company essentially serves as a one-stop shop: it offers 3D software for designing, the hardware needed to print designs, and a virtual store through which to sell items. To date, it has printed more than 1,000,000 products, and serves 10,000 independently run shops. Quirky (ââ¬Å"products invented by real peopleâ⬠) provides similar capabilities to inventors in the consumer products space, matching their inventions with category subject matter experts and specialists in market research, manufacturing and sales. 3. Widespread availability of ââ¬Å"maker spacesâ⬠and mentors There are two challenges that makers face as they begin the creation process: a physical place in which to build, and a ââ¬Å"coachâ⬠of sorts to help them through what can be a complex process. TechShop helps to solve both of these problems by providing maker space on a national level, thereby facilitating maker communities where knowledge distribution and transfers can easily take place. There are also countless community-centric maker spaces like the Artisans Asylum in Somerville, Massachusetts. The non-profit organization furnishes education, tools, and workspaces to empower hobbyists, artists, and early stage entrepreneurs, to create on large or small scales. The organizationââ¬â¢s goal? To help make the world a place where sincere, creative individuals are able to give form to their ideas. Betaspring, a mentorship-driven start up accelerator, was named this year among the top 15 start-up accelerators in the world. It has the distinction of having ââ¬Å"acceleratedâ⬠more hardware/physical technology companies than any other accelerator in America. (Disclosure: I serve as a mentor at Betaspring.) A year ago they began building on their increasing momentum by expanding their program, and adding new resources, including a ââ¬Å"Maker-in-Residence,â⬠ââ¬Å"Maker Fellow Program,â⬠and a small maker shop onsite in collaboration with Inventables, which offers a ââ¬Å"Designers Hardware Store,â⬠giving easier access to individuals and small teams seeking to source materials for reasonable prices. 4. Historically unprecedented access to capital Crowdfunding has been a huge catalyst in the surge of the Maker Movement. Instead of seeking one, or a handful of funders, makers now have access to many, many more, thanks to the Internet. Kickstarter, a crowdfunding platform, recently celebrated a significant milestone: it provided its billionth dollar of funding. Many companies that have received funding through itââ¬âand the myriad of other crowdfunding sitesââ¬âare also categorized as makers. Some Kickstarter beneficiaries includes Gustin, the San Francisco-based maker of high-end Selvedge Denim, as well as Pebble, the ââ¬Å"smartwatchâ⬠maker, and OUYA, the multi-platform console that can play games developed for Xbox, Sony Play Station, Wii and Nintendo on a single console. In 2013, there were a record 31 Consumer Electronics Hardware funding deals, with over $900M USD invested in devices such as the GoPro Extreme-Sports camera, the Nest Thermostat, and the Roku streaming media player. This is double the approximately $450M invested in this category in 2012, and there are early signs of even higher growth in 2014. All this signals that the Maker Movement is moving full speed ahead to revolutionize business, as we know it. In fact, some argue it already has. In my experience, and Iââ¬â¢ve got just a bit, Iââ¬â¢ve never witnessed a time as exciting as this one in which anything is possible. The number of global resources, and the technology that provides easy access, is empowering innovators of all types to nurture their ideas into reality. You could even say that all of us, on some level, are makers. But this also means that we all have a greater stakeââ¬âand responsibilityââ¬âin supporting sustainable innovation efforts that will make the world a better place for generations of makers to come.

The Great Gatsby By F. Scott Fitzgerald - 1122 Words
The Fresh Prince of West Egg Yo Halla The American dream is a desire to grow oneââ¬â¢s domain over more materialistic areas through hard work. In the book, The Great Gatsby by F. Scott Fitzgerald, this common strivation during the 1920ââ¬â¢s dramatizes becomes salient role.Two of the bookââ¬â¢s main characters, Nick and Gatsby, have opposite goals to satisfy themselves. Fitzgerald utilizes the motif of the American dream to express the theme concerning the hollowness of this idea by using Gatsby to symbolize it and using Nick to express Fitzgerald s own views on the subject. Gatsbyââ¬â¢s lifestyle to some seems to be utterly and definitely perfect and well rounded. People who have a feint knowledge of who this man is say that he is powerful, wealthy,â⬠¦show more contentâ⬠¦He describes his house in the novel as, ââ¬Å"My own house was an eye-sore,but it was a small eye-sore and it had been overlooked, so I had a view of the water, a partial view of my neighborââ¬â¢s lawn and the consoling proximity of millionaires - all for eighty dollars a monthâ⬠(9). The way that Nick so delicately lays out his home for the reader makes it sound like he is fine with his establishment, but not with his big-headed neighbors. Nick directly reflects how Fitzgerald feels about rich snobs. Nick even overhears some party guests gossip begins about him: ââ¬Å"One time he killed a man who had found out that he was the nephew to Von Hindenburg and second cousin to the devilâ⬠(65). The amount of people that Gatsby doesnââ¬â¢t know that are in his house partying makes it sound ridiculous to the reader. Fitzgerald sets the scene withdrawing the idea that people infected by this endless dream base their status upon wealth and property before even making a full deduction of character unbiased of rumors. Tons of people show up to these ââ¬Ëclassyââ¬â¢ parties and this allows Gatsby to flex his wealth by amusing them. Nick is not impressed: There was music from my neighbor s house through the summer nights. In his blue gardens men and girls came and went like moths among the whisperings and the champagne and the stars. At high tide in the afternoon I watched his guests diving from the tower of his

The cinematographic camera industry emerged in fact more than 100 years ago, it was only until recently that significant digital changes took place, apart from minimal technological improvements. Before the invention of digital cameras the main medium for shooting a movie was on celluloid film in which the quality of the image was very high from the beginning. However these cameras had some inconveniences. The cinematographer would have to set the lighting and frame to the directors vision and make sure that it was right. He could not see immediately if the scene was shot as desired and this caused the workflow to be very complex and time consuming which most producers would see limited.

Classical Conditioning and Associative Strength free essay sample
The experiment conducted was a 22 within subjects experiment. The 2 cue types were over-expectation and control whereas the 2 independent variables were salience. Subjects were randomly presented varying levels of salient stimuli in the form of food pictures. These pictures were then to be associated with an allergy score between 1 and 9. In the next phase, the subjects were given each cue type 8 times along with some filler cues arranged to some simple rules. The allergy ratings were also to be determined by the subject. The third phase combined the stimuli into a compound CS conditioning and subjects were asked to determine the allergy rating. The test phase involved participants being shown each of the previous foods one at a time. They would then determine the allergic reaction rating. Overall, the results of the experiment used an analysis of variables to show that the likelihood rating for the high salience cues were, on average, lower than those of the lower salience. A significant main effect with cue-type was found, indicating an over-expectation effect, of F(1,271)=25.à 758, plt;0. 001. This means that participants rated the compound cues in phase 3 as less allergenic than those that were elementally reinforced in phase 3. While there was no significant difference found between the elementally reinforced stimulus cues I and J (pgt;0. 05), there was found to be a significant difference between the compound cases involving stimulus cues B and F (plt;0. 05). Question 2: With compound CS, the associative strength is now dependant on the combined associative strength of all stimuli present and the total amount of learning. Generally in the Rescorla-Wagner model, conditioning is dependent on how effectively surprising an unconditioned stimulus is. With compound conditioned stimuli, this characterisation of surprise is altered. Instead of just a single CS being linked to a US, it is now the combined effects of all stimuli present which collectively predict the US. Over-expectation occurs when the collective associative strength of the various CS is greater than the total capacity to learn. To use the equation, ? V= (? -V) Note: We ignore ? and assume it a constant. The value of V would beà greater than ?. This occurs when the stimuli have been well presented and the associative strength of each individual stimulus is quite high. Because of this, when the target cue for, which the stimuli are conditioned for, is presented the subject expects the combined response of each individual stimulus. When the subject only receives the normal amount of reinforcement, it begins to expect less until there is no mor e association that can be gained from the combined effects of the condition stimuli. To use an analogy, a mouse is conditioned separately with a tone and a flashing light. Each of these stimuli provides one piece of cheese, with the mouse salivating when each stimulus is presented. If both the stimuli are presented together, the mouse expects two pieces of cheese and will salivate more than usual. However, only one piece of cheese is presented. As a result, the mouse begins to expect less of the compound stimuli until no further association can be gained. This consequently lowers the overall association by a certain rate until the total combined association is at total learning potential. Question 3: To get the over-expectation result, we must first have two fully conditioned CSââ¬â¢s which were separately conditioned. For example, let us use the A+ and B+ case. If we fully conditioned A+ and B+ separately, that means the associative strength of both would be 100%. Now, when we combine these two into a compound CS, the Rescorla-Wagner model states that the overall associative strength of the compound CS is equal to the sum of the all the stimuli presented in the compound trial. So with A+ and B+, their total associative strength would be 200%. However, the Rescorla-Wagner model only allows the maximum value of associative strength that can be conditioned to be 100%. The case of A+ and B+ is twice as much as this maximum value. Therefore, after repeated trials of the compound stimulus of A+B+ being paired with their US, the Rescorla-Wagner model predicts that the total associative strength of 200% will fall at the rate of their salience until it reaches a strength of 100%, the maximum level which can be conditioned. To show how an extinction event of a fully conditioned CS operates in the Rescorla-Wagner model. ?V= (? -V) Note: We ignore ? and assume it a constant. With a fully conditioned CS, ? , the total amount of learning, would be 0 as there is no more possible connection to make with a fully conditioned CS. V would be 100% as all possible learning has been made. Therefore, ? V=-? would be what is left over. This means that, in extinction, the rate at which the association strength, ? V, is lost at is ââ¬â?, the salience. Now, in the case of B+, it was a much more salient stimulus whereas F+ was a lower salient stimulus. Therefore, B would be lost at a faster rate than F. This is shown in the results with the likelihood rating of B being lower than that of F. Therefore, salience of each individual stimulus not only effects how fast the rate of association is increased but also determines, in the case of the over-expectation scenario, how fast the association of each individual, fully co nditioned stimulus is lost.
