    Avraham Trahtman, a mathematician who also toiled as a laborer after moving to Israel from Russia, succeeded where dozens failed, solving the elusive “Road Coloring Problem.”

    The conjecture essentially assumed it’s possible to create a “universal map” that can direct people to arrive at a certain destination, at the same time, regardless of starting point. Experts say the proposition could have real-life applications in mapping and computer science.

    The “Road Coloring Problem” was first posed in 1970 by Benjamin Weiss, an Israeli-American mathematician, and a colleague, Roy Adler, who worked at IBM at the time.

    For eight years, Weiss tried to prove his theory. Over the next 30 years, some 100 other scientists attempted as well. All failed, until Trahtman came along and, in eight short pages, jotted the solution down. the solution could have many applications.

    “Say you’ve lost an e-mail and you want to get it back — it would be guaranteed,” “Let’s say you are lost in a town you have never been in before and you have to get to a friend’s house and there are no street signs — the directions will work no matter what. [AP]

    We (the plain people)still have to go to work every day. I really couldn’t sleep or enjoy any meals before the “Puzzle” was solved. I am thankful that it was. Life must go on!
