17 13 12 03 09
08 03 05 05 0E
0F 0F 04 12 14
04 16 15 14 19
09 05 0E 01 ?
5 dollars to the person to posts the correct, full answer first.
EDIT: Any further hints would just make it too easy. Here is the solution:
By converting all of the numbers in the cube from hexadecimal to decimal, you get this:
23 19 18 03 09
08 03 05 05 14
15 15 04 18 20
04 22 21 20 25
09 05 14 01 ?
If you then convert each decimal digit to its corresponding place in the alphabet, you get this:
W S R C I
H C E E N
O O D R T
D V U T Y
I E N A ?
When this is read down the columns from left to right, it reads:
WHO DISCOVERED UNCERTAINTY?
The full and correct answer is, then:
Werner Heisenberg
