Entrepreneurship is the recognition and pursuit of opportunity without regard to the resources you currently control, with confidence that you can succeed, with the flexibility to change course as necessary, and the will to rebound from setbacks.
Bob Reiss
Entrepreneur’s Diary
I remain grateful for some good early advice. I had several inventions that had been taken to financial success by others. The benefactors sometimes said thank you. This made me all the more eager to take one of my own ideas to the real world. I had convinced myself that financial success and glory eagerly awaited me.
About fifteen years ago, I launched my first major entrepreneurial effort that revolved around proprietary technology used to produce seafood indoors in an environmentally responsible manner at a competitive price. The market for such a technology had to be huge I kept reminding myself, because seafood was (and still is) a significant contributor to the U.S. trade deficit.
Before everything else, getting ready is the secret of success.

Planning for my new fish farm start-up was going pretty well. After all, I had twenty years of experience at doing this. I thought I had everything under control. One of the major rules with starting a fish farm was that the backup generator be in place before you stock fish on the farm. This is because in the event of a complete power loss, you have about fifteen minutes to get the pumps working again or you’ll lose all your fish. I knew this. We were having one of our preconstruction meetings the week before we were breaking ground. Someone asked me about the backup generator. I said, “Don’t worry, these are pretty much stock items and we can get them on short notice.” Wrong! When I called our intended supplier, he informed me that these units were all custom built and the lead time was ten weeks. Fortunately for me, we wouldn’t be stocking fish for at least twelve weeks. I immediately ordered the generator. What’s the point? I should have constructed a network showing the interdependencies of all activities and events that would lead up to a successful conclusion of the project. If I had done this, I wouldn’t have had the shock I encountered. In my case, I was fortunately able to recover. Don’t rely on blind luck. Learn the basics of the two types of networks: the Critical Path Method (CPM) and PERT (Performance Evaluation Review Technique) charts. You won’t be sorry or be left up the proverbial creek without a paddle.
Project Scheduling
In project implementation the major concerns are: time, cost, and scope. In the project implementation phase, time is money. Longer completion times generally lead to higher costs. Mistakes and oversights are unnecessary costs; plus, it takes more time to correct them, compounding the situation. Not properly identifying the scope, or end objectives of the project will also impact cost and your ability to schedule events accurately in a sequential manner. Proper contingency planning can help avoid these unnecessary cost and schedule impacts. Of course, the costs avoided by careful and detailed planning cannot be quantified. Cost avoidance is a nebulous concept. Did you really save $5,000 in medical expenses by getting a flu shot? You’ll never know. You do know that the flu shot cost $20, however.
Men who are resolved to find a way for themselves will always find opportunities enough; and if they do not find them, they will make them.
Samuel Smiles (Scottish author 1812–1904)
Entrepreneurs are simply those who understand that there is little difference between obstacle and opportunity and are able to turn both to their advantage.

I think that I have developed a disruptive technology for producing fish in an indoor water-recirculation system. My design dramatically reduces the costs and complexity associated with the water-reconditioning equipment used in indoor fish systems. My design uses less space, is more environmentally compatible, is more reliable, and uses much less energy than other systems that most people are using for this purpose. As far as I can tell, there is nothing that our system doesn’t do better than any other system anybody is already using. What I don’t have is a practical means of demonstrating this technology. It is tough to be the groundbreaker. How then can I proceed? The producers that are using the technology that I plan to replace aren’t willing to convert their system to my system, because it takes them out of production for a considerable time, and to them, my system is unproven and therefore introduces a risk that they don’t have now.
So how do I demonstrate my technology? I have to become my own customer. I am going to have to build a fish farm that features my technology and its benefits. Where do I begin? I have to design a large-scale facility capable of making a profit, then build it, and then operate it. Now, I have to ask myself, “What business am I in? The system technology business or the fish business?” Sometimes it is hard to tell the difference. The truth is that I was about to be in both businesses. My immediate focus, however, was on the fish business. That is where the long-term, continual profits lie and where I pitched my investment proposal to investors. Apparently, I had just recognized my opportunity. Recognizing opportunity, preferably centered around some type of disruptive technology, is what Chapter 2 is all about. But what’s a disruptive technology? I’ll try to answer that question for you in this chapter and how it applies to a start-up.
During the early nineteenth-century craze for conducting kite experiments in lightning, deaths were not unheard of. Electrical physicists, meanwhile, were often shocked badly enough to collapse in the course of their work. However, the perils of electricity did not deter its proponents. Published in 1844, this enlarged collection of lectures by Henry Minchin Noad (1815–77) had proven immensely popular in earlier incarnations, eventually running to four editions and recognised as an invaluable textbook for electricians and telegraph engineers until the turn of the century. An electrical practitioner himself, Noad includes illustrated explanations of some of the most significant ideas in the field, and describes many of his own experiments, from his version of the lightning kite to a battery constructed with fifty jars and a thousand feet of wire. His work remains relevant to students in the history of science.
Originally apprenticed to a bookbinder, Michael Faraday (1791–1867) began to attend Sir Humphrey Davy's chemistry lectures purely out of interest. Although he soon recognised that science would be his vocation, there was no defined career path to follow, and when he applied to Davy for work he was gently told to 'attend to the bookbinding'. It was only after a laboratory explosion in which Davy partially lost his sight that Faraday was taken on as his amanuensis. From this difficult beginning stemmed perhaps the most famous scientific career of the nineteenth century. This three-volume collection of Faraday's papers provides a comprehensive record of a key branch of his work. Volume 3, first published in 1855, includes his landmark paper on the effect of magnetism on light (known now as the Faraday Effect), work on the chemical implications of magnetism, and a fascinating speculation on a link between electricity and gravity.

An electric arc is formed when a current passes between two conductors through a non-conducting medium like air. Although the phenomenon was discovered during early electrical experiments and utilised widely in lighting by the end of the nineteenth century, its problems were not fully understood. First published in 1902, this book represents one of the first systematic investigations of the electric arc, and the best-known work of suffragist and electrical engineer Hertha Ayrton (1854–1923). It includes a chapter on the history of the discovery, over a hundred illustrations and tables, and Ayrton's explanation of the enduring problem of arc instability. As a result of her research, she went on to patent anti-aircraft lights and new arc-lamp technology. She later became the first female recipient of the Royal Society's Hughes Medal. Remaining relevant to students of electrical engineering and the history of science, this book shares her insights and expertise.
