By  Interesting Engineering January, 26th 2017 Last year (2016), in the Interesting Engineering article entitled “Revolution in the Pythagoras’ Theorem?”, Dr. Luis Teia presented the proof of the Pythagoras’ theorem in 3D. This year, Teia explains in his recent (Feb 2017) peer reviewed…

“The story starts with Pierre de Fermat, one of the all-time great mathematicians, who claimed he could prove that the equation (a^n+ b^n = c^n) has no whole number solutions when n is greater than 2. There are some near…

“Primes are strange and curious numbers. There are, for example, no primes between 370,261 and 370,373, or between 20,831,323 and 20,831,533. And the primes 13,331, 15,551, 16,661, 19,991 and 72,227 and 1,777,771 are all examples of palindromic numbers. These are…

“First – and this begins to get technical – note that if a number is a composite, such as n=ab, then a and b cannot both exceed √n. For example, with the composite “21” – 21=3×7 – only 7 is…
