Digital Sum Digital Sum : The digital sum is the sum of the digits of a number taken iteratively till the result is less than 10. The problem statement is to get the number of integers less than 1 million where the digital sum is 1 and then, take the digital sum of this number which gives us the result. Note : Enable Javascript Here is the recursive function in C#. private void GetDigitalSum(double num, ref double num2) { //digital sum double sum = 0; for (int r = 0; r <= num.ToString().Length - 1; r++) { sum += double.Parse(num.ToString().Substring(r, 1)); } if (sum.Equals(1)) { num2 = -8; return; } else { if (sum > 9) { GetDigitalSum(sum, ref num2); } else

APJ Abdul Kalam and Divine Science The world is looking for, and is finding, a new science; this must be Divine Science. The divine world is looking to give that science. These are spiritual, mystical, religious and theological truths of the contemporary world. The Divine Science would be a result of breakthroughs in understanding the fundamental basis of reality such as quantum theory, relativity theory, chaos theory, general systems theory, string theory, and others. The magnitude of infinite possibilities within the human body and external cosmos is amazing. The Divine Science has to transcend the certainty of strictly Newtonian clockwork notion to a new vision of a holistic and unified cosmos rooted in a non-local quantum reality that is fundamentally spiritual as opposed to material. It may also be described as intrinsically evolutionary and harmonious. -- APJ Abdul Kalam

A novice in programming came up with this code... int num1 = 10; int num2 = 50; while (num1 < num2) { placeorders(); } What is the effect on the orders? Too many / too few / pretty much the same? Can you warrant a guess?.. Move the mouse over the text to see the answer... Guess the result...

Treasure this marvel : When I orbited the Earth in a spaceship, I saw for the first time how beautiful our planet is. Mankind, let us preserve and increase this beauty, and not destroy it.

Is it possible theoretically to have zones of backward time in the universe? This would still obey the laws of cause and effect where a more complex state would resolve into a simpler one. eg. On such a planet a human would be born old and die young. Cause and effect would still apply although defying commonly accepted norms and conventions. Entropy would still increase (where the state of more complexity would be the initial state and the simple state - a paradox). A state change would contribute to the increase in entropy and people would still be eccentric. Is such a scenario possible in realty? As far as i know there is nothing in science that a priori renders this impossible? -->
