They have to do with the nature of infinity. The most well known is the Runner's. If a runner thinks that a race is about going to the midpoint of the race and then the midpoint after that, he'll never finish. He'll complete 50%, then 75%, but will never reach the finish line. He can only get infinitely close.
Zeno was probably born in Alexandria, Egypt.
The earliest attestable accounts of mathematical infinity come from Zeno of Elea (c. 490 BCE? - c. 430 BCE?), a pre-Socratic Greek philosopher of southern Italy
Thales, Eucleides, Aristarchus, Zeno of Elea, Pythagoras, Plato, Aristotle, Aristarchus of Syracuse, Chilon of Lakedemon, Solon, Protagoras are an indicative list of philosophers - founders of the mathematics science.
In the naive set theory of the nineteenth century, the term universal set referred to the set of all sets. If one was doing set theory with objects that were not sets (these are sometimes called urelements), those were included in the universal set as well. However, Bertrand Russell and others discovered that this concept leads to paradoxes, such as the set of all sets not members of themselves (the universal set being a member of itself), which is a member of itself if it is not, and not a member of itself if it is. So axiomatic set theories were developed to hopefully avoid these paradoxes. It was also discovered that urelements are not necessary to do set theory that can be used as the basis of all areas of mathematics. In a more limited context, the term universal set or universe of discourse is used to refer to the set of things being discussed and studied. For example, in the area of the mathematical study of integers (positive and negative whole numbers), the set of all integers is the universe of discourse. This seems to be harmless in that it does not lead to paradoxes, as far as is known.
Infinity is not a number. There are different classes of infinity: The sets of natural numbers, integers, rational numbers all belong to the smallest class, with a cardinality of Aleph-null. The sets of irrational numbers and real numbers belong to the next higher level of infinity, with cardinality Aleph-One. Infinity can give rise to a very large number of apparent paradoxes - infinitely many of them?
Zeno's form of philosophy is called Zeno's Paradoxes.
Zeno is associated with paradoxes, particularly his most famous paradoxes about motion and infinity. He was a Greek philosopher known for his arguments that motion is an illusion and that reality consists of a series of unchanging moments.
Zeno of Elea.
Zeno was a respected philosopher in Ancient Greece. He lived before Aristotle and Plato. He was known for using paradoxes.
Zeno of Elea is the Greek philosopher credited with formulating paradoxes that defend specific beliefs about motion. His best-known paradoxes, such as the paradox of Achilles and the Tortoise and the Dichotomy paradox, were designed to challenge the idea of motion and the concept of infinity.
Zeno claimed that motion was impossible
When I was in ninth grade, I did one investigating Zeno's Paradoxes.
Zeno of Elea was a Greek philosopher known for his paradoxes, especially the paradoxes related to motion. His work aimed to challenge our understanding of space, time, and motion, ultimately exploring the concept of infinity to show that motion and change are illusions.
Zeno of Elea is known for his paradoxes that aim to challenge our understanding of motion and change. One of his most famous paradoxes is the Arrow Paradox, which questions the concept of motion by arguing that an arrow in flight is actually at rest at every moment. These paradoxes have had a significant impact on the study of metaphysics and philosophy of motion.
Zeno of Elea, a Greek philosopher, is best known for his paradoxes, including the famous Achilles and the Tortoise paradox. These paradoxes deal with concepts such as motion, time, and infinity, and have puzzled philosophers and mathematicians for centuries.
Zeno of Elea was born in the ancient Greek city of Elea, which is now known as Velia in present-day Italy. He was a philosopher known for his paradoxes that questioned our understanding of motion and change.
Zeno's reasoning, particularly his paradoxes involving motion and infinite divisibility, are widely debated among philosophers. Some argue that his reasoning raises important questions about the nature of space, time, and infinity, while others believe that his paradoxes can be resolved through mathematical and philosophical arguments. Ultimately, whether Zeno's reasoning is "correct" depends on one's interpretation of his arguments and the solutions proposed by later thinkers.
