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.
