Eight Primary Technological Developments

This text explores eight primary technological developments, triggers of innovation, and how we can cope with the increasing rate of change. It also covers various aspects of electronics, including transformers, diodes, vacuum tubes, and transistors. Additionally, it discusses the importance of understanding the difference between direct and alternating current, nanotechnology, and the concept of acid rain. The text highlights the contributions of famous scientists, the Luddite movement, and key topics in modern science such as global warming, carbon allotropes, gene splicing, and genetic engineering.

Presentation Transcript

  1. Eight Primary Technological Developments • Nuclear power • Telecommunications • Computer • Assembly line • Jet engine/Air Transport • Plastics/Synthetic polymers • Liquid fuel rockets • Television

  2. Triggers of Innovation • Deliberate attempts • Unexpected discovery • Unrelated developments • War and Religion • Accidents • Weather

  3. Burke shows to us • No inventor works alone • Rate of change is proportional to rate of information exchange • Medieval Ind. Revolution • 17th century specialization of knowledge via printing press • 19th century telecommunications

  4. How Do We Cope With Increasing Rate of Change? • Scrap all technology and go rural. • Selective research only. • Stop R&D and share out existing technology • Keep going the way have.

  5. Electronics • Transformer- changes AC voltage • Diode- allows unidirectional e flow Rectifier changes AC to DC • Vacuum tube - early electronics • Triode - electric switch & volume control. • Transistor- solid state electronics (doped Si or Ge) • Integrated circuit - Silicon chip electronics • Nanotechnology - Atomic size electronics

  6. Scientists

  7. Some more names

  8. What you should know • Major technological developments according to Burke • The six triggers of innovation and examples of each. • Explain why rate of innovation is proportional to rate of information exchange. • What can we do to better cope with the increase rate of technology change.

  9. What you should know • How a transformer works • 1000 volts and 2 amps enters a transformer with 10 coils and exits with 20 coils. What is the exit voltage and amperage? How does the wattage change? • What does a diode do and how does it work. Explain the vacuum tube and transistor. • Explain what a triode is, how it works and what it may be used for in electronic equipment.

  10. What you should know • The difference between direct and alternating current. • Why AC, not DC is used to transmit electricity over high voltage lines. • Explain nanotechnology and how it’s currently being used. Explain the possibilities of this new technology. • What is Acid Rain?

  11. The five great scientist discussed in class. There contributions to science and their connection to technology. What are Luddites and when and why were they created. George Washington Carvers contribution to science and technology. Are human responsible for global warming? What you should know

  12. Suggest at least two possible causes for our current warming trend. What are allotropes and how do carbon allotropes connect to nanotechnology? What is gene splicing and what purpose has it been used for. What is Genetic Engineering. What are stem cells and for what purpose is current research directed. What you should know
