The Einstein Theory of Relativity

The Einstein Theory of RelativityBy Prof. H.A. Lorentz of the University of Leyden

1. In order to measure the acceleration we let the body drop alongside of a vertical measure set solidly on the ground.
2. If in this case the speed were constant, then and this is in accord with the special theory of relativity.
3. It would be different if the measure moved with changeable velocity.
4. Thus we see that we also when the measure is not attached to the earth disregarding its displacement.
5.Of course in this case here under consideration the use of a measure fixed immovable upon the earth should merit all recommendation.
Questions -
1.How did the speed of light help prove the theory?
2.What would the difference be if the speed changed ?
3.What would be displaced by the change of light speed?
4. What immovable objects were used to measure the light?
Vocabulary -
1ether -the medium supposed by the ancients to fill the upper regions of space
2. therewith - in addition to that
3. velocity -rapidity of motion or operation; swiftness; speed
Literary Terms -
exposition - The speed of light is measured by a body laying vertical.
setting - space
Outline - The speed of light is measured and used to displace light.
