Lao Wang sells electric fans, which cost nearly 18 yuan and sell for 21 yuan. One day, the customer used 100 yuan to buy an electric fan, and Lao Wang had no change, so he exchanged money with the neighbor and used the change to find the customer 79 yuan. The next day, the neighbor found out that the 100 yuan was fake money, and Lao Wang gave the neighbor 100 yuan again.
Now ask: How much money did Lao Wang lose in total?
197?97?79?179?Still is......?

Albert Einstein (1879-1955), a world-famous German-American scientist, was the founder and founder of modern physics.
The landlord asked if this question was about physics, because if it was other fields, Einstein had a lot of problems at that time, such as medicine and archaeology, there should be a lot of them.
If you only refer to physics, of course, there are many problems that he can't now, because the division is too detailed now, even if he is a person of this era, he can't understand them all, and there is no way to prove that the theory of relativity is completely correct.
-
Simple, the Great Unification Theory, which he spent his whole life trying to achieve, has not been able to fully solve, the standard of the problems he has done but not made.
-
Let him have a little baby.
-
He has all returned to the West, what to do?
-
How much? Why are you going to test him?
-
If you ask him how to surf the Internet, he certainly doesn't know. Ha ha!
-
Where did we come from, and where are we going to **.
-
lz: Einstein would never have been able to do it.
-
Now he won't do anything about it.

Problem description: A is converted from B, B is generated from C, C is oxidized to D in air, and D has the smell of rotten eggs. What are A, B, C, and D?
Analysis: There is a problem: A and B can be converted into each other, B produces C in boiling water, C is oxidized into D in the air, and D has the smell of rotten eggs. What are A, B, C, and D?
Don't know the answer, do you? I don't know.
However, this question has stumped many scholars, even great scientists like Albert Einstein. If you don't know the answer, it means that you may be as educated as they are.
You say you know the answer, congratulations! Don't be too complacent, it is said that the first person to say the correct answer was Wang Er, who repaired shoes on the street. Just because you know the answer means you're probably as illiterate as he is.
The highly educated people I have taken the test have all inferred from the known condition that "d smells of rotten eggs". When I was in middle school, we learned that the smell of rotten eggs may be hydrogen sulfide, which is a toxic and harmful gas that can cause death when the concentration is high. So, what could be oxidized to hydrogen sulfide?
I am afraid that this question will stump a group of experts. There are several alternative answers, compounds are not necessarily "oxidized in the air". As for what A and B might be, let alone the professor, I'm afraid even God can't answer.
Actually, the answer is simple. Wang Er said: A, B, C, and D are chickens, eggs, cooked eggs, and rotten eggs, respectively.
Wang Er didn't go to school, he didn't know what hydrogen sulfide was, and what the smell of hydrogen sulfide was, he only knew that rotten eggs smelled of rotten eggs. The answer was revealed, and everyone thought it was funny: why did they forget such a simple truth?
Why is it that the simpler it is, the less easy it is to think of?

He saw the other man wearing a red hat and judged that he was wearing a black hat. Analysis: One of the 3 people wears a red hat on his head, then the remaining 4 hats are "1 red and 3 black", which are assigned to those two people, so when one of them sees that the other person's hat is black, the remaining hat is "1 red and 2 black", that is, the hat he is wearing may be red or black.
If you see that the other person's hat is red, the remaining 3 hats must be black, and the hat you are wearing is a black hat.

I don't know how much IQ there is, but it took me more than an hour to make it, mainly to determine the internal connections first, and push them slowly!
After verifying it several times, the following answer is exactly the same as ——
Color: yellow, blue, red, green, white.
Countries: Norway, Denmark, United Kingdom, Germany, Sweden.
Drinks: water, tea, milk, coffee, beer.
Cigarettes Dunhill Blends Pall Mall Prince Blue Master
Pets, cats, horses, birds, fish, dogs.
So it was the Germans who raised fish.
-
Are the Germans who raise fish?
The first yellow, Norwegian, water, dun, cat; the second room blue, Danish, tea, mixed smoke, horse; the third red, English, milk, pull, bird; the fourth green, German, coffee, pri, (fish); The fifth white, Swiss, beer, bule, dog, it is really difficult to check whether it is or not.

"1+1=0 is philosophy, 1+1=2 is mathematics, and 1+1=3 is literature".
1+1=1, e.g. 1 cup of water poured into another cup of water or 1 cup of water.
1+1=2, e.g. 1 woman and 1 woman sitting next to each other will be 2 women.
1+1=3, for example, 1 man + 1 woman gives birth to 1 child, the result is equal to 3 people, 1+1=4, for example, 1 man + 1 woman gives birth to 2 children, the result is equal to 4 people, if it is binary, the result is 10;
1 pot of soup + 1 rat poop = no more soup!
1 sperm cell + 1 egg cell = many, many cells.
From a chemical point of view, it can be equal to 3,C 02 CO2 from a mathematical point of view: 1+1 2;
From a linguistic point of view: two yellow orioles singing green willows, a line of egrets in the sky;
From a physical point of view: one positron + one negative electron 2 photons;
One carbon, one oxygen, one carbon monoxide;

Yellow, Blue, Red, Green, White, Norwegian, Denmark, United Kingdom, Germany, Sweden, Water, Tea, Milk, Coffee, Beer, Dunhill Blends, Pallmall, Prince Blue Master
Cats, horses, birds, fish, dogs, so it is the Germans who raise fish.

Einstein must have been in contact with these people, and these people were very clear, did you see, he mentioned it all smoke, and he must have liked some animals
He is best known for his discovery of the Theory of Relativity
1. The correct answer is that it must be true. Because the employees received the dedication award, the turnover exceeded 5 million, and if it exceeded 5 million, it exceeded 8 million. Because 7 of the 10 chain stores have more than 8 million, and the other 3 are less than 5 million. >>>More
