Brief Synopsis: The book, To Know a Fly, is about a scientist and his lifelong fascination with science and the fly. Vincent Dethier is a biologist that loves science and sharing it with the world. The book explains how flies work, shows how science works, and shows a researcher genuinely enjoying his job. He goes into great detail describing his experiments, observations, and discoveries of flies. Dethier chose to study flies for many reasons such as: “the fly is always with us… there are about 50, 000 kinds of flies sharing ‘our’ world,” the fly has many amazing and interesting characteristics, and flies are free, easy to come by, and very cheap to use for experimental purposes, plus animals rights activists do not usually harass scientists for experimenting on flies.
Of course, Dethier did mention at least one drawback of working with flies, which is that they have an “uncanny knack of escaping.” Dethier says, “An experiment is a scientist’s way of asking nature a question,” and in this book, he asks nature numerous questions about flies through his different experiments, the first of which set out to discover why a fly walks about in its food and constantly sticks out its tongue. This observation led to speculation that flies taste with their feet. By “gluing” a fly to the end of a stick and dipping its feet into a sugar water mixture, one can observe that the fly has a natural reflex of flicking out its proboscis. Modified versions of this test also proved that flies can distinguish between different kinds of sugars, and that they reject salty, bitter, and sour tastes. Flies ignore artificially sweeteners, and are gluttonous over a rare sugar called fu cose.

Imagine that you are in charge of setting up a civilization. What would be the first thing that you did? Many people might choose to set up a system of rules and regulations to better control the way the civilization acted and regulated it. After all, a civilization cannot grow and prosper without rules. The civilization would die because no food would be gathered and no one would work for ...
Flies are similar to many people in the fact that they “prefer what tastes good to what is nutritionally best.” Other experiments were performed to learn more about a fly’s tastes and feeding habits, and the role the fly’s tiny hairs play in taste. By applying tiny drops of sugar mixed with alcohol to the tip of a fly’s hair, the proboscis was extended. Also mixing a bit of salt with the drop showed that the same hair tasted salt as well as sugar. Thus, it was determined that the hairs were actually complex sense organs. Other experiments were conducted to find out how much a fly eats in a day and what factors regulate its intake. It was observed that flies have no mechanism for regulating calorie intake or the concentration of its body fluids.
Numerous other experiments were conducted to learn a variety of other important information about flies and how they function including: hunger and food preferences, thirst, satiation, food-searching patterns, effect of light on flies, dancing patterns, and brain complexity. The final experiment discussed involved determining whether or not flies could learn through either conditioning or habituation. Unlike humans and many other animals, the fly cannot be conditioned to respond and has no capacity for learning, so basically the fly is stupid, but aside from that, it really is a fascinating and interesting creature. The book ends by discussing how important a scientist’s work is to him or her, and that all the research, experimenting, and publication are well worth the reward of knowledge obtained and shared with the world. Analysis: Dethier wrote this book for the non-scientist in an attempt to communicate the fascination and methods of science to as many people as possible.
I believe he wanted to clear up many misconceptions that people may have about scientists and the scientific process. Dethier uses straightforward and easy to understand language to describe the experiments and discoveries of flies, which gives the reader a whole new perspective on both flies and science in general. Dethier sets out to teach the general public how amazing and interesting even the smallest and seemingly insignificant creatures can be. He also wants to demonstrate the steps and processes of the scientific method by applying them to specific examples. I also believe that Dethier is trying to gain respect and appreciation of scientists from society in general. He wants people to see a scientist as a human with a family, a job, and problems just like anyone else.
The Term Paper on How Could a Scientist Defend the View That Science Has Failed Mankind in View of the Large Number of Problems Created?
How could a scientist defend the view that science has failed mankind in view of the large number of problems created? Science has created problems for mankind. Science is a blessing all right, but it is not an unmixed blessing. Science has made life easier and more comfortable. Science has made it possible for us to communicate with each other readily and quickly and it has made travel easy and ...
His job just happens to deal with science, and it is important to note “he probably spends a greater period of his life preparing for his career and works longer and harder at it, at a lower salary than many of his fellow men.” A scientist devotes his life to a search for truth and knowledge because of an insatiable curiosity and hunger to know. In this book, Dethier is exposing the day-to-day work of a scientist, or more specifically a biologist, and is showing society that like any occupation there are frustrations, successes, and rewards. For scientists rewards often are not monetary, but in feeling that they are contributing to the well-being of society and providing new knowledge to the world. Evaluation: I strongly believe that Vincent G.
Dethier had a great talent for writing as well as for scientific experimentation and exploration. He made this book understandable and interesting to the non-scientist, which I feel is a great accomplishment because I, for one, and not usually intrigued by science, but did enjoy reading this book and feel that I learned a lot from it. Dethier did a wonderful job of portraying the way the scientific method is implemented to learn and discover new things. I feel that he succeeded in making people aware of the importance of science as well as all the animals that share our world, no matter how small they may be.
He made the perceived “insignificant” fly seem significant and interesting. The fly is so much more complex than I had ever realized. I believe Dethier makes his readers more aware of the world around them and helps them to appreciate how intricate nature is, and that science is our way of unraveling the mysteries of our planet. Reading this book has given me a new understanding and admiration for scientists and the work that they perform day in and day out. Their job seems very tedious and painstaking at times, and I greatly admire their patience and perseverance. I never really realized before that scientists are creative people too, and the way they express their creativity is through imaginative and innovative experimental designs.
Book Review: Every Day by David Levithan
“I am a drifter, and as lonely as that can be, it is also remarkably freeing. I will never define myself in terms of anyone else. I will never feel the pressure of peers or the burden of parental expectation. I can view everyone as pieces of a whole, and focus on the whole, not the pieces. I have learned how to observe, far better than most people observe. I am not blinded by the past or ...
I am a creative person and use it daily in my field of study, and greatly respect the creativity of others. I do not believe that Dr. Gordon could have chosen a better book for this class to read and learn from. Yes, it is a book about science, and many people have negative attitudes about science, but I feel that this book helps the non-scientist be more open-minded about it. I would recommend this book to anyone that does not understand the way science and scientists operate, or anyone that has false perceptions or prejudices about science.
I believe that Vincent G. Dethier succeeded in making his voice heard, and helping to spread his knowledge and love of science to others.
