Can you solve the time travel riddle? - Dan Finkel

Your professor has accidentally stepped through a time portal in his physics lab. You’ve got just a minute to jump through before it closes and leaves him stranded in history. Your only way back is to grab enough colored nodules to create a new portal to open a doorway through time. Can you take the right amount of nodules to get back to the present before the portal closes? Dan Finkel shows how.

*Bold of you to assume that I'm helping this guy out*

"You only have one minute to go in the portal"
*alright then...lemme spend 3 minutes thinking about it*

[Grapes-nkvk]

Step one: confirm you have green eyes
Step two: ask the nodules to connect correctly so you can leave.

Of course, the hexagon is still the bestagon.

Now I understand why there were exactly 6 infinity stones

[linali]

*tells riddle*
me: uh 6?
*says answer is 6*
me: IM SO FREAKING SMART

0:14 love how I just casually watch as my boss "accidentally" steps through a time portal

[Tippex_Official]

0:09 if he’s called Ramsey, I assume he rants at his workers

Also, here’s the solution:
1. Bring all the nodules,
2. Make tons of 3 node triangles till you get what you want

Just grab him through, you have long enough arms

"Your internship at Ramsay's physics lab has been amazing."
Also me: *tries to put the apple in the square slot*

[xiupingliu]

Me: Wait so how many nachos does he need?

How does one ACCIDENTALLY fall through a time vortex?

[ShauryaSingh-tsoc]

Can't I just throw the box of nodules in the portal so that the professor figures out himself ?

[yanagelfand]

I went from the opposite and tried to find a way to AVOID same-color triangles. The fact that a hexagon is symmetric made it easier. So I tried different combinations of the two colors on the outline (there are only three). All the times I stumbled across two rays of the same color from the same vertex, I added the third line of the different color (worst case scenario). And all the times it eventually led to a triangle. With a triangle, a rectangle and a pentagon the same strategy led to "winning" (there is a way not to form a triangle), so I increased the quantity of vertexes until I found out that a hexagon doesn't work like that, so it should be the correct answer. The bonus riddle works the same way.
I see that this way is less logical and more intuitive, but for me it was easier to actually see how it can play out.

"Whats the minimum number of nodules"
Me: *Take 3 and a risk also* .

[Tombee]

Me: five sounds nice-No 6, 3 for 2 triangles.
Ted-ed: the answer is 6
Me: yes big brain time

[stormysamreen]

Me: * grabs six chrono nodules *
Me: * opens portal *
Me: * gets splinched because there *was* a chance of the portal collapsing, no matter how few you bring *
Me: Well, fml.

now he knows where the lamb sauce went

[daveteves]

Thanks TedEd! Now I know how much modules I need when this problem arises.
