Düsündürücü sorular..

• Ivmeli hareket neden bir referansa gerek duymadan
  hissedilebiliyor?
• Sabit hizda olmak ne demek? Hangi referansa göre
  sabit hizda? Referansin sabit hizda oldugunu
  nerden biliyoruz?

5
Relational space of Leibnitz
6

• The static shift argument

7

• The kinematic shift argument

Newtons Principia
Issac Newton (1643-1727)
9
What Is Absolute Space?

• Infinite, unchanging, 3-dimensional box
• Existing as a substance independently of material
  objects and the spatial relations among them.

10

• Under Newtons conception, absolute motion is
  motion relative to absolute space itself.

11

• Newtons theory of absolute space
• The two universes are not identical although
  different absolute locations are indiscernible.

Newtons Rotating Spheres

• How to account for the inertia force?
• Is it caused by the rotation of the spheres
  relative to other things in the universe?

16

• How to account
• for this tension
• in empty space?

17

• Conceivable?
• Only relative motions among objects make sense.

18

• Influences from the distant fixed stars
• All influences are derived from relative motions
  among objects.

19

• But how can a few distant stars can make such a
  difference?
• Mach Force you feel represents the combined
  influence of all the other matter making up the
  universe. You feel acceleration when you
  accelerate relative to the mass distribution of
  other material inhabiting the cosmos...

Challenges to Mach

• What If we rotate charged liquid? Can one explain
  electric and magnetic fields with rotating
  universe? (Feynman)
• Rotating Charged Liquid will produce
  electromagnetic radiation. Can one explain the
  radiation flux and work done on bucket with
  rotating universe?

21
Challenges to Mach

• Is losed kinetic energy same in rotating universe
  and rotating bucket?
• Can Mach explain Sagnac effect?

22
Challenges to Mach

• Efect of Shape of bucket?
• Effect of Machs Force on water drops?
• What if we rotate several buckets?

23

• 1873 - James Clerk Maxwell publishes his Treatise
  on Electricity and Magnetism.
• 1878 to 1880 - Maxwell suggests absolute velocity
  of Earth in aether may be optically detectable
• 1887 - the Michelson-Morley experiment (MMX)
  produces the famous null result.
• 1905 - Albert Einstein publishes Special Theory
  of relativity
