Hello,

my name is Bruno Curfs.

I studied mathematics in Utrecht, Netherlands. I worked in ICT from 1995 - 2007. I'm an author now; check out my book "The End of Religion, The Beginning of Self. Using the Hebrew Alphabet as Secret Wisdom Key" at http://TheEndOfReligion.weebly.com. My book about the code the Bible is written in, also features some logical and mathematical riddles, just for the fun of it.

Mathematics has always remained a hobby. ..

Now and then, I am browsing the internet and am interested in unsolved problems like:

- Does there exist a magic square of 3x3 of which the entries are squares? - Do there exist odd perfect numbers? - Are there infinite number of prime twins? - Can every number of the form 4/n with n>1 be written as the sum three Egyptian fractions, i.e. can you find x,y,z integers with 4/n = 1/x + 1/y + 1/z ? - Is there a terminating algorithm for Rubik's cube using (almost) only turns that lower the entropy of the cube?

- Unresolved paradoxes - Are there an infinite number of integers not containing 0 which are NOT Friedman numbers? - Are there an infinite number of integers which are NOT Curfs numbers?
 * (Curfs numbers are numbers which allow for expressions of themselves using the same rules as Friedman numbers, yet also allow the use of 0^0 = 1), see the talk on Friedman numbers.

Etc.
