I am not an expert on the history, but I believe that this method was never used by navigators because reliable predictions of the moons' positions came in the 20th century. Before the models coming from simulations, there were functions published...
I am not certain about what is going on here, but there are some issues with the code which are making things unnecessarily complicated. inter = fscore /@ start; minimum = Position[inter, Min[inter]]; current =...
Take a look at the documentation http://reference.wolfram.com/language/tutorial/RandomNumberGeneration.html Several methods are supported but the default uses cellular automata. It used to be rule 30, see Stephen Wolfram's ["A New Kind of...
Did you post yet about the intersecting 3D fractal trees? Your project about them from the 2013 Wolfram Science Summer School was a good example of what happens at the [summer school][1]. Most people don't come with a specific project like this...
You have a syntax error, instead of list[3]=new; to replace the third element, you should use list[[3]]=new; In general, using list manipulation functions will avoid these sort of syntax errors. Here are a few comments. ...
Palindromes in base 2 are rare but for a number to be a palindrome in some base is not so rare. For instance there are a few other bases that make 2015 into a palindrome: Select[Range[2, 2013], # == Reverse[#] &[IntegerDigits[2015, #]] &] ...
Take a look and consider applying to this year's summer school for doing projects using Wolfram Language https://www.wolframscience.com/summerschool/ Most students are in their early 20s but the range has been 14-76. The Wolfram Science Summer...
There are general ways of doing these sorts of things but this is a little simpler if you look at it the right way.  For instance this is the union of the language 1a(any)aa(any) with the possible exceptions 1aa(any). Then just combine the...
One way to do this is with BitXor, e.g., label your people 0,1,2,...15 and then at week n the ith person is paired with BitXor[i,n] This is symmetric for each week n, i.e. when the formula assigns x to y it also assigns y to x, because Xor[a,b]==c...
The original CellularAutomaton lecture was given in 2004 http://www.wolframscience.com/summerschool/resources/NKSCA-phillips-ss04.cdf Some of the other lectures from past summer schools can be found at...
