You probably don’t have to read it all, but at least a passing familiarity with parts of it will probably be useful some day. Until the 20th century, Euclid’s Elements were more widely read than any other book in the world (except the Bible) and had a profound influence on the foundations of mathematics.

Yes, Euclid’s Elements is still worth studying. Your second question, what books can you recommend for Euclidean geometry, depends on what you mean by Euclidean geometry. If you mean Euclidean geometry the way Euclid did it, then his Elements is the best text.

The index below refers to the thirteen books of Euclid’s Elements (ca….The thirteen books of Euclid’s Elements.

Every prime number (in the usual definition) is a natural number. Thus, every prime number is finite. This does not contradict the fact that there are infinitely many primes, just like the fact that every natural number is finite does not contradict the fact that there are infinitely many natural numbers.

Since each term of the product is finite, the number of terms must be infinite; therefore, there is an infinite number of primes.

Mathematicians are stunned by the discovery that prime numbers are pickier than previously thought. Although whether a number is prime or not is pre-determined, mathematicians don’t have a way to predict which numbers are prime, and so tend to treat them as if they occur randomly.

Euclid and His Accomplishments Euclid’s story, although well known, is also something of a mystery. He lived lots of his life in Alexandria, Egypt, and developed many mathematical theories. He is most famous for his works in geometry, inventing many of the ways we conceive of space, time, and shapes.

Every prime number can be written in the form of 6n + 1 or 6n – 1 (except the multiples of prime numbers, i.e. 2, 3, 5, 7, 11), where n is a natural number. Method 2: To know the prime numbers greater than 40, the below formula can be used.

Apart from 2 and 5, all prime numbers have to end in 1, 3, 7 or 9 so that they can’t be divided by 2 or 5. So if the numbers occurred randomly as expected, it wouldn’t matter what the last digit of the previous prime was.

A clear rule determines exactly what makes a prime: it’s a whole number that can’t be exactly divided by anything except 1 and itself. But there’s no discernable pattern in the occurrence of the primes. That’s because after the number 5, there are only four possibilities — 1, 3, 7 and 9 — for prime last digits.

The number googol is a one with a hundred zeros. It got its name from a nine-year old boy. A googol is more than all the hairs in the world.

According to many books (such as Mathematics, A human Endeavor by Harold Jacobs)2 the googol is one of the largest numbers ever named. The googolplex is 1 followed by a googol zeros. More recently, Skewer’s number is the largest number ever used in a mathematical proof.

No. They’re all the same. No because infinity doesn’t have a numerical value, it’s a concept of something that never ends and it doesn’t follow the rules for our numbers that we’ve created.
