The Atomic Theory

  • Scientific theory of the nature of matter
  • Positions of electrons: probability

How is it that scientific knowledge changes over time?

What was wrong with the original theory?

Other AOK's?

Art-Shakespeare

Kuhn (1970): Normal and Revolutionary science

"Successive transition from one paradigm to another via revolution is the usual developmental pattern of mature science."

Other viewpoints?

-Serendipity

Falsified rather than changed

-Problem with induction

- Models get modified, not changed

What has caused this 'change' in scientific knowledge?

Scientific Development

Focus Points

  • Development of technology
  • Shared knowledge

Introduction

Real-life situation

Knowledge Question

"How can it be that scientific knowledge change over time."

IN CONCLUSION

Perspectives / Counterclaims

The accepted views of science knowledge can change over time. Changes can result from new science observations, but can also be affected by social, political or religious convictions. To develop a deeper understanding, one need to investigate the context of the time in which science ideas were developed.

Conclusion

The Atomic Theory

Modern Atomic Theory

Probabilistic Cloud

"Scientific Knowledge is in Perpetual Evolution, it Finds Itself Changed from One Day to the Next"

- Jean Piaget

Can we consider this a change in scientific knowledge?

How come the Atomic Theory changed over time?

Ernest Rutherford

(1912)

Cell Theory

Discovery of the central nucleus and orbiting electrons

Niels Bohr (1913)

- Developed Rutherford's Model

- Electrons occupy certain orbits/shells

Real-life situation

Introduction

  • If scientific knowledge is only ever provisional, can we trust it to provide us with truth about the world?
  • Or should we be as skeptical about its findings as less objective areas of knowledge?

Constant Figures

G: universal constant of gravitation

G = 6.67 x 10^-11 NmKg

k: Coulomb's constant

k = 8.99 x 10^9 NmC

Boiling point of water

Conversion from Kelvin to Celsius

'Constant' Laws

  • Laws that never change
  • Remain constant even through change in environment and society.

JJ Thomson

BOYLE'S LAW (1662)

NEWTON'S 3 LAWS OF MOTION (1697)

EXAMPLES

DIETS

  • One nutritionist might argue that some fats are healthy for you and that you need a certain amount of it in your diet. Other nutritionists can argue the complete opposite or state another amount you might need to take.

WEATHER

  • There are millions of weather forecast websites showing the same day, however, different weather conditions for the same place. Science can be compared to this. There are billions of websites, articles, books and experiments done, however, all the values fall within a certain "probabilistic cloud".

Discovery of the electron

Atom contains smaller particles

Is it nearly the same?

Scientific Knowledge

A.O.K

  • Natural Sciences

W.O.K

  • Language
  • Sense Perception
  • Reason
  • Intuition
  • Imagination

Definition:

"Branch of knowledge dealing with systematic truths showing the operation of general laws."

Key Words:

  • Systematic: methodical, accuracy
  • Truths: reality
  • Operations: functions and applications
  • Laws: theories and certainty

Definition of quote:

  • Perpetual Knowledge: infinite, forever changing
  • Perpetual Evolution: infinite development

Infinite development = scientific knowledge

PROVISIONAL & FALLIBLE
