    Your research team has found a prehistoric virus preserved in the permafrost and isolated it for study. After a late night working, you’re just closing up the lab when a sudden earthquake hits and breaks all the sample vials. Will you be able to destroy the virus before the vents open and unleash a deadly airborne plague? Lisa Winer shows how.
    Lesson by Lisa Winer, animation by Artrake Studio.

    The ending here has a new meaning. Since the "safe " room by the entrance was clean, it became contaminated when you entered and then returned. The last room was also contaminated, the door leading to the exit.
    Since you escaped.... you let some of the virus out when you left. The virus is out.... and it's in the world... and you, Mr. Traveling Salesman, are carrying it wherever you go.
    You should have just just flipped the switch and let yourself be buried in concrete. Now the virus won't get out, because you're contaminated. Your suit is, and you can't get out of it. It's a one way trip in realistic terms.

    Hey, I just realized. By this very same logic, you can actually Start and End in the Same Room. Why? Well, first of all, remember the solution. You can go back to the first room immediately after destroying the second room you enter. That also means that you can go through the entire facility and return to the very room you Started in as the last place you go.
    Mind you, the logic puzzle REQUIRES you (for some reason) to end on the opposite corner, but still.

      I'm sorry to tell you that your idea fails twice !
      -Firstly, you don't have time to come back to the first room every time !
      1:14 1:22 you can see how the instant concrete takes just a few seconds to completely fill the room!
      - Secondly, let's say you are starting in room a5 (1st column, 5th row from the bottom)
      After you pull the lever in room b5, you can safely return in room a5, but after you pull the lever in room a4 , you CANNOT come back to the starting room. If you did that, you would be STUCK ! 😂
      (And also, you would break the rule "Once you enter a contaminated room, you must pull the switch" ! The first room is not immune to the virus, so it would become contaminated as soon as you move from room b5 to a5)
      =)

    • @thexp905

      ​@@francescof3267 Well, no. You are in fact wrong. If you go from A1, all the way down to A4, flicking the leavers in 2 and 3, you can still path back up to the starting room with only overlapping the starting room. So their statement is true that the only thing preventing it is the end room requirements. You seem to be stuck that you have to loop back to the starting room every flip, instead of leaving the double-back till the end.

The second part says that the virus isn't real. If the second part is true, then the first is false, because it assumes the virus isn't real and thus, it wasn't made in the first place. The statement requires both parts to be true at the same time which is impossible, so, the statement is false.

    I had another idea. The chatacter could open all doors. When he reaches the last room, he may pull the switch to destroy it. So it means that he destroys every room from the end of lab. And as he reached the first room, he pulls the switch and as the timer starts he quickly exits this first room.

    • @CliffordCollinsloves
      @CliffordCollinsloves 7 років тому +36

      If the exit room has a negative pressure (like modern operating rooms), then when you open the door for a short period of time, air is sucked into the room and the virus does not really get out. Minus the ones on your clothes of course.

    That answer is wrong. Here is the correct way:
    Step 1: Don't go into contaminated rooms. Cut the power from the backup systems so the vents don't open instead.
    Step 2: Call the superiors.
    Step 3: Little bit of panic, be yelled at by the boss.
    Step 4: Get lots of help (both nationally and internationally) to aid in the cleanup.
    Step 5: Slowly decontaminate each room 1 by 1. Don't worry about how long it takes. Days, months, years... Doesn't matter, must make sure everything gets sterilized.
    Step 6: Finally, walk through the now decontaminated exit.
    Step 7: Invest in a better designed lab and adhere to stricter protocols for storing hazardous materials.

      3. When u reach the last one, destroy it and get out of the lab.

      Osama Jweihan - Computer scientist here. In fact, if you proved that the Hamiltonian path problem could be solved in polynomial time (i.e. faster than trying every possible combination), you would simultaneously prove that EVERY problem categorized as NP-complete can also be solved in polynomial time. Similarly, proving that it cannot be solved in polynomial time simultaneously proves that all other NP-complete problems cannot be solved in polynomial time.
      Solving this problem pretty much translates to instant fame btw, as it has eluded computer scientists for quite a while now. The current concensus is that all NP problems cannot be solved in polynomial time since otherwise we would have found an efficient algorithm for at least one of these problems, but such an argument is not a very rigorious proof, and it's still technically possible that humans have just been too dumb to find an efficient algorithm yet.

    There is another solution (if you can leave through the entrance) The moves would be Down 3, Right 3, Up 1, Left 2, Up 1, Right 2, Up 1, Left 3, and then leave through the entrance.

      Killigram Gamer You realize how you'd have to implement that onto trillions of cells at a time. If you're referring to CRISPER we still have a long way to go.

      bousio it doesn't work like that. 1. You suffocate and die. 2. By opening the doors u let the virus out. 3. Your suit would be contaminated with the virus so u wouldn't be able to leave which means u will suffocate.
