SUMMARY

Zeno's paradoxes of motion are fundamentally flawed due to their reliance on the incorrect assumption that instantaneous velocity must equal zero. The discussion confirms that motion is indeed possible, as evidenced by everyday actions such as typing. The invention of instantaneous velocity and advancements in mathematical limits effectively resolve the paradoxes Zeno proposed. Overall, the consensus among participants is that Zeno's paradoxes do not hold true in the context of modern physics.

PREREQUISITES
  • Understanding of instantaneous velocity in physics
  • Familiarity with the concept of limits in calculus
  • Basic knowledge of motion and kinematics
  • Awareness of historical philosophical arguments in physics
NEXT STEPS
  • Study the concept of instantaneous velocity in classical mechanics
  • Explore the mathematical principles of limits in calculus
  • Investigate the implications of Zeno's paradoxes on modern physics
  • Review the historical context of philosophical debates in motion
USEFUL FOR

Students of physics, mathematicians, philosophers interested in the foundations of motion, and educators seeking to explain the resolution of Zeno's paradoxes.

if zeno's paradoxes are true and motion is impossible, then how does an electron reach the electrostatic field of another electron?

Motion is possible. Your fingers moved as you typed your message, did they not?

False premise. That was easy...

Yeah. I'm not sure what the problem is here. They aren't true.

I believe it was the invention/discovery of instantaneous velocity that solved them.

His paradoxen are based on the assumption that, if one measures the velocity of an object at an instant in time (i.e. duration = zero), one must get velocity of zero. Not true.

None of the Zeno's paradox is in fact a paradox. He simply created infinite series from simple situations, but the mathematics about limits was evolved enough to solve the problems he had created.

As several posters have already remarked, they aren't.

Since the OP question is based on a mistaken premise, this thread is closed.
