This is a humor PDF 41-slide presentation about how some people could reason on the apparently simple field of the prime numbers distribution.
Was Giordano Bruno accused of saying: “I don’t care if 1 is prime or not, if 2 is prime or not, if 3 is prime or not. All I care is that there are more stars in the heavens than primes in the earth?”
Is it true that George Washington said: “What’s the difference between prime numbers and composite numbers? There are no real differences, remember: E pluribus unum?”
Is it true that Erwin Schrödinger said: “3 is a prime, 5 is a prime, and 7 is a prime, however, 9 has a dual prime-composite state that can collapse to one side or the other depending on the observer’s cat?”
And don't leave aside the politicians, you know, they're everywhere. Is it true this statement attributed to the former US president George W. Bush: “3 is prime, 5 is prime, 7 is prime, and 9 … well, any odd number can be prime as long as it is not 9?”

In 2006, the astrophysicist Alexander Zaitsev, stated what is known as the SETI paradox. The SETI paradox is about ....
“the insistent quest for intelligent signals from other civilizations and the persistent aversion to any attempts to transmit such signals from Earth.”
In other words, the paradox is about... you give me all your big data, but I keep silent about mine.
Of course, in the field of inter-galaxy signaling we are just beginning to turn on the radio. No matter what scientists and technician say, we know almost nothing about space, much less how to handle space encounters.
A Short History Of The Cartesian Coordinates.
Click the image to download the slide presentation: A Short History of the Cartesian Coordinates.
The first intent of formalizing the geometry concepts and knowledge came from Euclid’s Elements (c. 300 BC). The Elements is probably a collection of theorems previously proved by other mathematicians that predated Euclid with some original work; among them Pythagoras.
However, geometry became analytic with the publication of René Descartes' (1596–1650) masterpiece in 1637: Discourse on the Method.
But some authors claim that the discovery of the coordinate system should be attributed to Pierre de Fermat (1601–1665), because Fermat had more geometrical insight than Descartes.
