Question

Which scientist/s proposed the theory of relativity?
1. Watson and Crick
2. Albert Einstein
3. Charles Darwin
4. John Dalton

Answer 1

Correct Answer - Option 2 : Albert Einstein

The correct answer is Albert Einstein.

• Relativity is a theorem, formulated by Albert Einstein.
• It states that space and time are relative and all the motion must be relative to a frame of reference.
• It is a notion that states, laws of physics are the same everywhere. This theory is simple but hard to understand.
• It states:
  • There is no absolute reference frame on can measure velocity if the object or momentum is only in relation to other objects.
  • The speed of light is constant irrespective of who measures it or how fast the person measuring it, is moving.

• Charles Darwin: 
  • Darwins proposed the theory of evolution by natural selection.
  • First formulated in Darwin's book "On the Origin of Species" in 1859, is the process by which organisms change over time as a result of changes in heritable physical or behavioural traits.
• Watson and Crick's model was composed of two strands that are connected by bonds between nitrogen bases that have a spiral shape.
  • The model showed that the DNA molecule is a double-helix.
  • The DNA molecule produces two new complementary strands. Each strand of the double helix serves as a template for the new strand.
• John Dalton first proposed an atomic theory of matter and he named it Dalton's atomic theory.
  • Dalton’s atomic theory was able to explain the law of conservation of mass, law of constant composition and law of multiple proportions very successfully.
