Virtual Mind Reader

posted in: Fun, Uncategorized | 4

You think it’s impossible? Try it here. You could be very surprised.

This is good and interesting “joke” that I had put on my Web site couple of years ago. I almost forgot it, until I’ve seen suddenly, these days, that number of visits to my site has been increased significantly. Looked to Google analytics and found out that popularity of page Virtual Mind Reader is increasing. Some forums and blogs put link to this page and many people obviously wanted to check if computer can read their minds. And they learned that computers can even over Internet and long distance. 🙂

Anyway, you might know what mathematical background of virtual mind reader is, but I will not disclose it here. I just want you to think a little bit about it and find explanation.

Have a fun!

P.S. Thanks to all of you who linked me on your blogs, forums and web sites.

    Dobra fora! Rezultat operacije sa brojem koji zamislimo mora uvek biti 9 x i (i=1 to 10) a “mind reader” uvek kada se startuje ovim brojevima dodeli isti simbol. Tako nam čita misli. Dobra, dobra fora.

    Da, upravo tako. Evo matematičkog objašnjenja:

    Svaki dvocifren broj se može predstaviti kao ab gde su a i b cifre tog broja. Vrednost tog broja je 10a+b. Ako se od vrednosti broja oduzmu njegove cifre, onda je računica sledeća: 10a+b-a-b=9a. Dakle, rezultat je uvek deljiv sa brojem 9. Ako pogledate pažljivo, videćete da su simboli pored svih brojeva deljivih sa 9 isti.

    Kad probate ponovo, on samo promeni simbole da ne bi bilo očigledno.

    Jednostavno, zar ne? 🙂
