Albert Einstein "So have you worked it out yet? Who owns ze fish, ja!"

How is this answer derived? Logically, the problem can be broken down as such:

There are 5 houses lined up – so the easiest way to represent this is as 5 boxes, each with 5 traits – nationality, color, beverage, cigar, and pet. I used a spreadsheet for this and made 5 seperate sheets – one representing each house. Each sheet had the following:

Now, its process of elimination. This is where things can get tricky if you don’t have things written out. As soon as you figure out a trait for one of the houses, eliminate that trait from all other houses.

First, we know that the norwegian lives in the first house, so he cant live in the others. We also know that the center house drinks milk, so we can eliminate that, and also that the norwegian lives next to the blue house – house 2 is therefore blue.

The green house is on the LEFT of the white house, meaning the norwegian cannot live in a green or white house since it is on the end (ruling out white – no houses are to the left of it) and since the house next to it is already established as blue (ruling out green). This also means that the middle house cannot be white, since the house to the left of it is blue.

At this point, house 1 can be yellow or red – except that a brit lives in a red house, and house 1 is owned by a norwegian. So, house 1 is yellow, eliminating yellow from the other houses. We also know that the man living in the yellow house smokes dunhill – so we can mark that as house 1 too.

The man who keeps horses lives next to the man who smokes dunhill, so house 2 keeps horses. We also know the swede keeps dogs, so house 1 cannot keep dogs.

The Dane drinks tea, the green house drinks coffee, and the man who smokes blue master drinks beer – eliminating all of these from house 1. House 1 drinks water – the man who smokes blends lives next to the man who drinks water, so house 2 smokes blends.

House 5 cannot be green either, since the green house is to the left of the white house, and there is no house to the left of house 5.

House 2 is not a brit (house not red) or a swede (doesnt keep dogs). He also does not drink coffee (not in a green house), or drink beer (does not smoke blue master). He therefore drinks tea, which makes him a Dane.

House 3 cannot be green (drinks milk), which makes it red, and therefor owned by the brit.

This means house 5 is white, and house 4 is green. For house 3, we can also eliminate dogs (swede keeps dogs), blue master cigars (bluemaster smoker drinks beer), and prince (german smokes prince).

The green house drinks coffee – house 4 is green, so beer is eliminted from that. This means that the owner cannot smoke blue master, and therefore must smoke prince – making the owner german, and eliminating dogs as a possible pet. Thus, house 5 is a beer drinking swede who likes dogs.

We also know house 3 smokes pall mall, and therefore rears birds.

We now have our choices of who has fish narrowed to down to house 1 (norwegian) and house 4 (german). The final clue is that the man who smokes blends lives next to the man who keeps cats – house 2 smokes blends, so either house 3 or 1 rears cats. Since house 3 is already established as a bird lover, house 1 must rear cats – this eliminates cats from the German, and leaves only the fish. Therefore, the German owns fish.

1. Albert Einstein’s Riddle – With Solution Explained

Albert Einstein has a riddle to share

According to Einstein, roughly 98% of the world’s population cannot solve this riddle. It is one that uses pure logic – no fancy math is required.

1. In a street there are five houses, painted five different colours.
2. In each house lives a person of different nationality
3. These five homeowners each drink a different kind of beverage, smoke different brand of cigar and keep a different pet.

The Question: Who owns the fish?

Hints:

1. The Brit lives in a red house.
2. The Swede keeps dogs as pets.
3. The Dane drinks tea.
4. The Green house is next to, and on the left of the White house.
5. The owner of the Green house drinks coffee.
6. The person who smokes Pall Mall rears birds.
7. The owner of the Yellow house smokes Dunhill.
8. The man living in the centre house drinks milk.
9. The Norwegian lives in the first house.
10. The man who smokes Blends lives next to the one who keeps cats.
11. The man who keeps horses lives next to the man who smokes Dunhill.
12. The man who smokes Blue Master drinks beer.
13. The German smokes Prince.
14. The Norwegian lives next to the blue house.
15. The man who smokes Blends has a neighbour who drinks water.

If you are able to solve this, consider yourself in the top 2% of the World’s population.

You can find the solution, along with an explanation here.

1. Why Is Albert Einstein Famous?
2. What Did Albert Einstein Invent?

Albert Einstein is not famous just for riding his bike

Albert Einstein is famous for a number of reasons (two theories of relativity, nobel prize), but perhaps his most well known accomplishment is a very simple mathematical equation: e=mc^2. This is probably the most famous math equation ever written (except maybe 2+2=4); it is extremely simple to understand, yet the implications of it led directly to the atomic bomb and nuclear power.

The equation is actually energy = mass times the speed of light (c) squared. Since the speed of light is constant, and an extremely large number, this implies that a *vast* amount of energy can be created from very very little matter. In other words, you could power New York City for months from a gallon of water.

In addition to this equation, Albert Einstein also has a few well known quotes attributed to him.

“Things should be made as simple as possible, but not any simpler.”
“Two things are infinite: the universe and human stupidty, and I’m not sure about the universe.”
“Reality is merely an illusion, albeit a very persistent one.”
“The only thing that interferes with my learning is my education.”

1. What Did Albert Einstein Invent?

While not an invention in the literal sense – it was not a creation per se – Einstein’s Special Theory of Relativity was, and is, one of the most ground breaking science breakthroughs of all time. This was made in 1905, and built on the three century old Galileo principle of relativity. Some of the central assertions to this theory are that time and space are relative to the observer, the speed of light is the maximum attainable velocity in the universe, and that mass and energy are interchangeable according to the equation E=mc^2.


While Einstein cannot be credited with the invention of the atomic bomb, the famous equation above is the theoretical basis of it. Energy (E) = mass (m) x the speed of light in a vacuum (c^2). The most famous consequence of this was its application in the atomic bomb – By measuring the mass of different atomic nuclei and subtracting from that number the total mass of the protons and neutrons as they would weigh separately, one could obtain an estimate of the binding energy available within an atomic nucleus. This could be (and was) used in estimating the energy released in the nuclear reaction, by comparing the binding energy of the nuclei that enter and exit the reaction.

Einstein also gave the solution to the question, “Why is the sky blue”, in 1911, through a formula that explained how light scattered off of air molecules.

In 1916, Einstein expanded his Special Theory of Relativity to include a General Theory of Relativity. This theory is primarily concerned with large scale effects of gravitation. This has been one of the cornerstones of cosmology and our understanding and view of the universe – primarily that large celestial bodies produce curvatures in space-time, which forms a gravitational field. From a planets gravitational pull of its moons to black holes, the General Theory of Relativity is incredibly broad.

The Bose-Einstein Condensate is a state of matter formed by bosons cooled to temperatures very near to absolute zero. It was proposed by Einstein in 1925 and built upon the work of Satyendra Nath Bose, hence the name.

Einstein was an incredible individual who changed the way we see and explain our universe – even over 50 years after his death, this theories are still in use and referenced.

Thomas Edison has been attributed with a number of interesting quotes.

I have not failed. I’ve just found 10,000 ways that won’t work.

Genius is one per cent inspiration, ninety-nine per cent perspiration.

Edison seems to be of the opinion that to create truly amazing inventions, all you really need to do is work hard and don’t give up.


Einstein was also known to have a few interesting things to say:

Only two things are infinite, the universe and human stupidity, and I’m not sure about the former.

One of the best quotes ever.

One of the most famous quotes comes from Ben Franklin:

Early to bed and early to rise makes a man healthy, wealthy, and wise.

You may not agree with the sentiment, but it is one of the most quoted statements in American history.
