1Technology and Science Presented By:Amy CheemaSamar AzizSana AzizArzoo SalamiFauwaz S. HusseinPatrick Martin
2What Is Technology? Definition The technical means people use to improve their surroundings.Technology is people using knowledge, tools, and systems to make their lives easier.Benefits of Technology
3Science and Technology Science vs. TechnologyIs technology an “applied science”?Theories of ScienceTheories of Technology
4Technology throughout History The Stone AgeThe Bronze AgeThe Iron AgeThe Industrial RevolutionThe 20th Century
5Technological Systems Definition – This word is interchangeable with “system”Three parts:InputsProcessesOutputsFeedback
6Inputs – The Resources Used by the System There are six major inputs used by a technological system:PeopleNatural Resources (materials)Capital (tools and machines)Finance (money)Knowledge (information)Energy
7Processes – The actions taken to use Inputs Two major types of processes:Production ProcessesManagement ProcessesThese two processes are united. They work together to get desired outputs.
8Outputs – The result of the System Two types of outputsSystem outputEx. Manufactured product, constructed work, communicated message.Other outputEx. Scrap and waste, pollution
9Goals of TechnologyTwo Primary goals for any business to be successful:To meet human needsProfit
10Types of Technological Systems Manufacturing SystemsConstruction SystemsCommunication SystemsTransportation Systems
12The Problem May have to invent a solution to a problem May have to change an existing design
13InvestigationFUNCTION: Must solve the problem described in the design brief. “What exactly is the use of the article?”APPEARANCE: Shape, color, and texture should make the object attractive.MATERIALS: Availability? Cost? Physical Properties (strength, rigidity, color, durability)CONSTRUCTION: Hard to make?SAFETY: The object must be safe, should not cause accidents
14Developing Alternative Solutions Write or draw every idea on paper as it comes to youThe more ideas you have, the more likely you are to end up with a good solution
15Choosing a Solution Your own skills The materials available Time needed to build each solutionCost of each solution
16Detailed Drawing Overall dimensions Detailed dimensions Material to be usedHow it will be madeWhat finish it will require
17Models and PrototypesModel is a full-size or small-scale simulation of an objectPrototype is the first working version of the designer’s solution
18Testing and Evaluating Does it work?Does it meet the design brief?Will modifications improve the solution?
19Manufacturing How many to make? Medical equipment produced in hundreds, nuts and bolts produced in millions
21What Counts as Technology? ObjectsKnowledgeActivitiesA ProcessSociotechnical System
22Technology is Related to Science Purpose of technology: change in the material environmentPurpose of science: understanding of nature.
23Technology Involves Design Design is the center of technologyDesign process: begins with perception of a need, continues with formulation of a specification, and ends with an evaluation of the solution.
24Technology Involves Making Motivating factor: desire to fulfill a need.All designs should be made or realized.If the need is to be fulfilled, the design is to be evaluated, and the design activity is to have been purposeful and worthwhile.
25Technology is Multi-Dimensional Technology is performing a multitude of functionsExamples: working with others, operating within budgets, persuading decision makers, communicating to clients and working to deadlines.
26Technology is concerned with Values Value decisions may be called for not only in relation to the specific design criteria, but also in relation to the rightness or wrongness of a particular solution in ethical terms.
27Technology is Socially Shaped Determined by social interests.Technology is shaped by society, by consumer choice.Technology can shape society. For example, the technology of the motor car has shaped our environment and our whole way of life.
28Technology and Science, go way back… The word science is derived from the Latin word scientia, which simply means knowledge, and the German word wisenschaft, which means systematic, organized knowledge. (Why?)The word technology is derived from the Greek words, techne and logos, which means art or craft. (How?)Science has a relatively recent history – perhaps four centuries, whereas technology has a much longer history, a history as long as humanity.
29How Technology and Science are related… Goal: the creation of artifacts and systems to meet people's needsGoal: the pursuit of knowledge and understanding for its own sakeDesign, invention, productionDiscovery (controlled by experimentation)Analysis and synthesis of designAnalysis, generalization and creation of theoriesThe search for and theorizing about new processes (e.g. control; information)The search for and theorizing about cause (e.g. gravity; electromagnetism)Taking good decisions based on incomplete data and approximate modelsDrawing correct conclusions based on good theories and accurate dataDesign, construction, testing, planning, quality assurance, problem solving, decision making, interpersonal and communication skillsExperimental and logical skills
31Applications related to science and technology Electronic devices: Invention of radio- Science: sound, wave, and optics- Technology: assembly of speaker, electric circuits, and antenna.Health Services: From use of remedies to proper medications- Science: Physiology of human body- Technology: combination of various salts.
