Introduction and Rationale
“In a race the quickest runner can never overtake the slowest, since the pursuer must
first reach the point whence the pursued started, so that the slower must always hold a
lead.” - Aristotle1
Zeno of Elea was a Greek mathematician and philosopher who was known for
his stimulating paradoxes that tried to prove what some might believe impossible.
Zeno’s paradoxes, in some form, have been the base for almost all of the theories
generated about space and time and infinity since his time to our current one, such as
Tomson’s Lamp. His ideas and principles influenced Greek philosophers such as
Aristotle to observe the world in a different, more mathematical way. One of his most
famous paradoxes was

This is a clear example
of a day to day paradox that we encounter and do not stop to think about it. Its
principles are the same as Zeno’s.
In this paradox, consider a lamp with a switch. The switch enables to turn the
lamp on and off. Thomson started at a time 0 by switching the light on and at the end
of one minute turned it off. Now he took halve a minute to turn the light on again and
a quarter of a minute to turn it off. This continuous motion creates an infinite
sequence. The graph below illustrates this idea;
Whereas, the sum of the infinite series is two minutes.
Thomson aim with this experiment is to answer the following question: after
two minutes is the lamp switched on or off? On and Off are represented in binary
form as 1s and 0s, respectively.
