Can you solve the virus riddle? - Lisa Winer

View full lesson: ed.ted.com/lessons/can-you-sol...
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.

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.

[@Snowmon89]

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.

[@NumbToons]

Yeah that's true, nice job!

[@poeticdavide]

EXACTLY! That was my solution, in fact!

[@francescof3267]

@Snowmon89 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.

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.

[@benedictadu1254]

The reason why the entrance room got contaminated is because the air lock was opened for too long but from the exit it is opened once so there is no contaminating the environment

[@CliffordCollinsloves]

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.

[@markimoo4u]

I did receive the nod at the traveling salesman problem at the end

You should destroy entrance room after airlock opening (04:20). If opening a door contaminate the room, wouldn't it apply to the part of the building after the "exit" door?

[@kjrbh]

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.

My first time solving one of your a riddles ! I still can't believe it was it easier than the other ones ??

[@shadowplays2617]

This all could have been solved if they kept all the samples in ONE room

[@CaptFrost-ed8ij]

But if you open the door to the contaminated room, the previous room may get contaminated

[@jamesrodriguez474]

Same idea

[@Joy-le9fy]

@@CaptFrost-ed8ij ohhh, i think he thought of a new puzzle! How would you make it so you destroy the contamination, while also leaving the building, and having destroyed all of the contamination without it being spread to your previous rooms with you and to avoid it from leaving the building as well

It's like graph theory and the bridges of Königsburg, but better because of its new element. I also like this riddle because it employs a concept that is little understood.

[@rynez2844]

I think before leaving the exit room, you go and pull the lever on the other room that is left out after going to all the room leaving one room at the side of the exit and then you leave

[@Kateaclysmic]

1:13 you enter the room and there are switches on both sides leading to both doors. They are both 'up' or not activated. 1:17 the door on the right opens and you exit without either switch going down. The switches are pulled by someone/something once you've already exited and the door on the right is almost closed. Presumably both switches are connected so go down at the same time. Where/when do you do whatever it is that pulls the switches down?

[@alexandermcclure6185]

You walk through the door. He said "you can't walk out of the room without causing the self-destruct sequence" so if you exit the room the switch gets pulled

[@oliviamontes8164]

You could also just go one row and then go to the next row down

Or turn off the ventilation system

[@lochlain7840]

bousio ikr

[@nut1867]

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.

[@-xxicedtodeathxx-8790]

Ethan Ferns better you than the rest of the world

[@twaynewade2544]

Ethan Ferns Your suit would be contaminated even with this solution though

[@OwO-]

isn't your suit designed to not be contaminated ? otherwise, wouldn't you die no matter what you do ?

[@snakeliquid34]

figured it out. because the entrance isn't contaminated, it allows you to go back into it and continue on the other way.

[@Tony-eo4ov]

I was thinking about sacrificing myself which is the only way to destroy the virus completely, but when he said "survive to tell the story" then everything changed, and I had to carry the virus out and tell the story.

[@internetperson9813]

The real question is why the vents open when the virus is leaked.

[@nancyhey1012]

@@internetperson9813 I agree, that is a horrible design!

[@kaboomwinn4026]

@internet person then remember all the room except the 1 room is contaminated if you leave the exit it will spread The virus anyway without decontamination room. you remember if you back track back to the first clean room After pulling the lever. it still contaminated the room on the right and have to pull the lever the first room to move down a room.

[@blockyboxhead]

the one thing i looked was you have to pull the switch to fix the room, but i realized you dont need a switch in room one
