TOK Exhibition Prompts

Tok Exhibition Prompt 33 – How is current knowledge shaped by its historical development?

Object 1: The Periodic Table of Elements

  • Theme: Knowledge and Technology
  • Rationale: The development of the Periodic Table by Dmitri Mendeleev in the 19th century, and its subsequent evolution, exemplifies how current knowledge in chemistry is deeply rooted in its historical development. Mendeleev’s ability to predict the properties of then-undiscovered elements showcased the predictive power of scientific knowledge, with the table’s ongoing refinement reflecting the accumulation of empirical evidence and theoretical understanding. This object highlights how historical scientific breakthroughs continue to shape and inform the structure of current knowledge, guiding research, education, and application in chemistry.

Object 2: A Copy of “On the Origin of Species” by Charles Darwin

  • Theme: Knowledge and the Knower
  • Rationale: Darwin’s seminal work on the theory of evolution by natural selection laid the groundwork for modern biological sciences, offering a radical new perspective on the development of life on Earth. The historical context of Darwin’s work, including the scientific and societal resistance it faced, underscores how current knowledge in biology is influenced by its historical development through debates, evidence gathering, and the gradual acceptance of revolutionary ideas. This object serves as a testament to the dynamic nature of knowledge, shaped by historical discoveries, theoretical challenges, and the ongoing quest for understanding.

 Object 3: Architectural Blueprints from Different Eras

  • Theme: Knowledge and Technology
  • Rationale: Architectural blueprints from different historical periods, such as those from ancient Roman engineering to modern skyscraper designs, illustrate the evolution of architectural knowledge, techniques, and styles. These blueprints reflect the cumulative nature of technological and artistic knowledge in architecture, showing how innovations, materials science, and aesthetic concepts have evolved in response to societal needs, technological advances, and cultural influences. This object demonstrates how the historical development of architectural knowledge informs current practices, blending tradition with innovation.

Object 4: An Ancient Astronomical Almanac

  • Theme: Knowledge and the Knower
  • Rationale: Ancient astronomical almanacs, used for tracking celestial events, agricultural cycles, and religious observances, showcase the historical roots of astronomical knowledge. The transition from observational astronomy based on the naked eye to the use of telescopes and modern astrophysics illustrates the profound impact of historical developments on our current understanding of the universe. This object highlights how knowledge is not static but builds upon the foundations laid by previous generations, evolving with new discoveries and technological advancements.

Object 5: Early Mechanical Calculator

  • Theme: Knowledge and Technology
  • Rationale: The early mechanical calculator, such as the Pascaline invented by Blaise Pascal in the 17th century, represents the beginnings of computational devices. The historical development of calculators from mechanical to electronic forms underpins the current state of computing technology, illustrating the trajectory from manual calculation methods to sophisticated digital computers. This object emphasizes the importance of historical inventions in shaping the tools and methodologies that define contemporary knowledge in computing and mathematics.
