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.
