Review Questions

• How did the 1905 paper change the way scientists understood time and space?
  • The 1905 paper revolutionized the understanding of time and space by introducing the concept of special relativity, which asserts that time is not an absolute constant but is relative to the observer's motion. This means that two observers moving at different speeds will measure different times for the same event, leading to phenomena such as time dilation. By linking time and space into a single continuum known as spacetime, Einstein provided a new framework for understanding physical phenomena.
• Discuss the implications of mass-energy equivalence as proposed in Einstein's 1905 paper on future scientific advancements.
  • The mass-energy equivalence principle introduced in Einstein's 1905 paper has had profound implications for scientific advancements, particularly in nuclear physics and energy production. It laid the foundation for understanding how nuclear reactions convert small amounts of mass into large amounts of energy, leading to both nuclear power generation and atomic weaponry. This principle has shaped our approach to energy sources and remains central to many areas of research in modern physics.
