## Can you solve “Einstein’s Riddle”? – Dan Van der Vieren

Before he turned physics upside down, a young Albert Einstein supposedly

showed off his genius by devising a complex riddle involving

this list of clues. Can you resist tackling a brain teaser written by one of the smartest

people in history? Let’s give it a shot. The world’s rarest fish has been

stolen from the city aquarium. The police have followed the scent to a

street with five identical looking houses. But they can’t search

all the houses at once, and if they pick the wrong one,

the thief will know they’re on his trail. It’s up to you, the city’s best detective,

to solve the case. When you arrive on the scene,

the police tell you what they know. One: each house’s owner

is of a different nationality, drinks a different beverage, and smokes a different type of cigar. Two: each house’s interior walls

are painted a different color. Three: each house contains a different animal,

one of which is the fish. After a few hours of expert sleuthing,

you gather some clues. It may look like a lot of information, but there’s a clear logical path

to the solution. Solving the puzzle will be

a lot like Sudoku, so you may find it helpful to organize

your information in a grid, like this. Pause the video on the following screen to

examine your clues and solve the riddle. Answer in: 3 2 1 To start, you fill in the information

from clues eight and nine. Immediately, you also realize that since

the Norwegian is at the end of the street, there’s only one house next to him, which must be the one with the blue walls

in clue fourteen. Clue five says the green-walled

house’s owner drinks coffee. It can’t be the center house since you

already know its owner drinks milk, but it also can’t be the second house,

which you know has blue walls. And since clue four says the green-walled house must be directly

to the left of the white-walled one, it can’t be the first

or fifth house either. The only place left

for the green-walled house with the coffee drinker

is the fourth spot, meaning the white-walled house

is the fifth. Clue one gives you

a nationality and a color. Since the only column missing both

these values is the center one, this must be the Brit’s red-walled home. Now that the only unassigned

wall color is yellow, this must be applied to the first house, where clue seven says

the Dunhill smoker lives. And clue eleven tells you that

the owner of the horse is next door, which can only be the second house. The next step is to figure out what

the Norwegian in the first house drinks. It can’t be tea, clue three tells you

that’s the Dane. As per clue twelve, it can’t be root beer

since that person smokes Bluemaster, and since you already

assigned milk and coffee, it must be water. From clue fifteen, you know that the Norwegian’s neighbor,

who can only be in the second house, smokes Blends. Now that the only spot in the grid

without a cigar and a drink is in the fifth column, that must be the home of the person

in clue twelve. And since this leaves only the second

house without a drink, the tea-drinking Dane must live there. The fourth house is now the only one

missing a nationality and a cigar brand, so the Prince-smoking German

from clue thirteen must live there. Through elimination, you can conclude

that the Brit smokes Pall Mall and the Swede lives in the fifth house, while clue six and clue two tell you that these two have a bird

and a dog, respectively. Clue ten tells you that the cat owner

lives next to the Blend-smoking Dane, putting him in the first house. Now with only one spot left on the grid, you know that the German in the

green-walled house must be the culprit. You and the police burst into the house, catching the thief fish-handed. While that explanation

was straightforward, solving puzzles like this often

involves false starts and dead ends. Part of the trick is to use

the process of elimination and lots of trial and error

to hone in on the right pieces, and the more logic puzzles you solve, the better your intuition will be for when and where there’s enough

information to make your deductions. And did young Einstein

really write this puzzle? Probably not. There’s no evidence he did, and some of the brands mentioned

are too recent. But the logic here is not so different from what you’d use to solve equations

with multiple variables, even those describing

the nature of the universe.

HOW DARE U ! The brit drinks the tea! This whole vid is completly nonsence.

Would anyone mind suggesting me some books with riddles like this?

It took me about 15min. Pretty easy

1.6K disliking this … is literally impossible.

I did it in half an hour 😂

Pretty damn hard

German : "Really? You HAD to put the blame on me AGAIN? "

YAAYYYY I SOLVED IT !!

I solved this in class:)

I solved it in around 20 minutes and I’ve never been prouder of myself

Why can't they just let the dog sniff out the culprit

every drink and cigar almost explodes everytimeNo one: That isn’t normal

Everyone: Totally fine here

This is the first ever TED-Ed riddle I’ve solved!

I can’t believe I spent an hour figuring this out. Pretty proud of myself tbh 🙂

YALL I ACTUALLY SOLVED THAT

now what.

How 'bout some backup?

What’s the song that’s playing when he starts explaining the riddle?

The only riddle I could ever solve

Wait! This is the fish from the fish riddle!

I can't believe I actually solved this 😭 I love Sudoku so it'd be a shame if I didn't get this

Had to include cigar. Aye, my man😂

First time I got an answer correct

Me and my cousin spent nearly an hour doing this. We got it right!

Yeah but whose left?

i completed this when i was younger and couldnt seem to forget the answer.

How could i forget this, it was once in a lifetime😂

i completed this when i was younger and couldnt seem to forget the answer.

How could i forget this, it was once in a lifetime😂

But of course how will the theif escape with the fish so fast? If he ran fast then fish will drown or bowl will break

I took 20-30 minutes to solve it and i'm so happyyy!!! Great riddle

Is it a big deal to solve the riddle? Because I solved it yesterday but i dont know how to feel about it

i got it… my brain is too big

As the detective thinks, the robber will have more time escaping lol

took an hour and a half but i got it

listening to that smooth walk through of the solution is so theraputic like

Did it in about 20 minutes, it wasn’t too hard

Britain:

doesn’t drink teaillusion: 100Just spent 20 minutes on this and finally got it, what a fun way to start the day

4:14 green walled house huh? To me that looks blue ;P

This wasn't all that hard

Need 1 hour for me to solve it :""

But hey, congratulation for me 🤯🤯

After an hour and a half I finally got it. I might not of went about it as logically as they did but I got it 😁

I did this at school

Nithyanandha can solve answer any Einstein riddle 🤣🤣🤣🤣

solved it

It took 30 minutes but was really fun and challenging solving this.

messes up at 4th and 5th clue because i thought the white house was left of the green house not vice versaGot it!!!!

I did it, i actually solved this puzzle

I used to do a bunch of puzzles like this in elementary i love these

How did he create it?! So fascinating!

First riddle I got right after trying like 4. Took like 15 mins but I finally got it.

I wish it weren't 11 PM because then I would have spent an hour working on this with colored markers.

I was presented with this riddle ten years ago. I couldn't solve it. Today, I paused the video and I solved it and I was right. God I feel accomplished.

dude was just lonely , all his neighbors had pets. 😂

I solved it.. wohoo

I really just guessed the number 4 house cause my brain give me insticts that told me the answer i was rigth

I managed to solve it

SPOILER THE ANSWWR IS HOUSE 4By the time I hear the police say one of the houses has the fish, I'm leaving.

The answer is they too long and I got away.

My solution i search one of the houses when the thief notice and try to escape the 2 cops will catch him

So the police are colorblind cuz there were colors?

Why don't the thief just run when we're taking so much time solving the crime?

bruh when I solve the riddle, this fish will be dead already

omg it took me a 15 minutes to solve it

I solved it in 15 minutes.when I completed and checked my answer it was correct. I felt so happy feeling I am smart

Einstein was German so the answer must be German

It took me half an hour to solve the riddle and I finally did!

Are u sure the brit isn't the thief..?

How can a brit NOT drink tea… Hmmm something is fishyThis literally took me 10 mins to solve

Plot Twist: It’s a plastic fish

Easier solution: More Police come and go in all five houses at once

Hurrah ! I have solved it in 1 hour and 20 minutes …. 😊😀

But the theif will surely run away in the meantime .😎😅

Solved this in about 15 minutes, using a spreadsheet

I feel so clever now

Instead of cracking open your skull, call for more officers and storm all the houses at once. 😂😂😂

PS: Since it's written by Einstein, it's quite obvious that the Germans are gonna bear the blame.

turyfhrjht

It took me a solid 30 minutes of scribbling, but I solved it. And now it’s 12:07 AM. I think I’m going to go to sleep now…

Good night to any fellow midnight puzzle solvers! 🌙🌟💫

The German is always the most suspicious person. "Sigh"Vielen Dank

only Sherlock Holmes could answer this riddle…

(With the help of two ten year olds, of course :3)

After 2 hours finally I get the answer

Its the first riddle that I solved

The real answer is how can smell a fish in a bag so how would you find it

Or the police could stay outside and watch while you check all the houses… bam solved it in 2 minutes

Understood : 0%

Enjoyed : 100%

It took me half an hour to solve it

Solved it myself! Took me about 10 minutes.

I admit i was stuck for few minutes until i realized that the person who smokes Blue Master and drinks Root Beer can only be Swede with the Dog in last house.

After that point it was just filling the table with what was left.

hold up. Its said that the owner with the green walls has a neighbour LEFT from him, not RIGHT from him. cmon

YESSSSSS IT TOOK ME ONE HOUR TO SOLVE IT AND TWO PAGED OF PAPER BUT I SOLVEDDD IT

IT WAS THOSE GOD DAMN GERMANSSS
