Programmer needed, I believe that the VMS words are just letters that equal numbers which are not represented as a language. I’m in search of a programmer who can apply my cipher to the VMS corpus of words and correlate it to a database of an Old English Dictionary associated with Gematria numbers. The programmer would have to use another piece of code which checks for grammar. Also the programmer would have to gain access to every VMS vord and substitute my cipher to every letter of it. What’s needed? 1) Entire list of all the VMS vords 2) Old English Dictionary 3) Dictionary is associated with standard Ordinal English Gematria 4) A grammar checker 5) My C…

Hello everyone, Can anyone find what is the digit at the unit's place of the product 81x82x83x....x89, without actual multiplication?

Although I have a question, I've decided to post this in the Brain Teasers & Puzzles section. The infinite hotel paradox goes like this: We have a hotel with an inifinite amount of rooms filled with an infinite amount of guests. A new guest comes in to check in therefore we move each guest to the next room and are able to free room nr 1 to be occupied by the new guest - nothing changes, we still have an infinite number of room and an infinite number of guests. Same thing if a guest checks out...we move all the guests this time to the previous room and we end up with the same result - infinite number of guests and rooms. Nice classic paradox. My question is...it …

Suppose there is a series as: [math] a, a+b^2, a+b^2+c^3, a+b^2+c^3+d^4,... [/math] where a is constant and- b=a+k1 c=b+k2 d=c+k3 where- k2=k1+m k3=k2+m Can anyone find the formula to get the nth term of the series?

You have 3 boxes. 1 box contains nails, 1 contains screws and 1 contains both. All three boxes have the wrong labels. You can open boxes and remove items from them but you cannot look in the boxes.

George likes to play with marbles. He has got a jar full of marbles of different colours. One day, he started to pick the marbles out of the jar. In the first picking he took away 1 marble, in the second picking he took out 2 marbles, in the third he took out 3 marbles from the jar - each time picking up as many marbles as the number of picking. He found that after fifth and seventh picking, the number of marbles that were left in the jar was a perfect square. Now, can you find the number of marbles that was in the jar at the beginning?

Suppose a glass tumbler contains a certain number of bacteria. A scientist found that the number of bacteria doubles itself after every one second by asexual reproduction (completely hypothetical). He observed that after one minute the glass was full of bacteria. Can anyone tell when was the glass half-full ?

There are 12 golf balls in a box. You know that one flawed ball accidentally got mixed into the batch. The flaw is that the weight is off but you don't know if it is too heavy or too light. You can only detect the flaw through the use of a balance (not a scale) that can only detect which of two trays contents is heavier. Describe the most efficient method (fewest number of balances) to identify the flawed ball. To help you describe the method use the following codes: U = Untested L = golf ball from a Lighter group H = golf ball from a Heavier group E = golf ball from an equal or balanced result (good golf ball). Example: After balancing 6U vs 6U you ge…
