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?

Why Is Albert Einstein Famous?
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.

What Did Albert Einstein Invent?
Albert Einstein is one of the most well known American inventors/physicists of all time – but his famous equation – e = mc^2 is just one of his many inventions and discoveries.
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.
Quotes About Inventions – Quotes From Inventors
Inventors seem to have something about them that many others don’t. That little bit of creativity that, if they were never to invent something, would make them seem a little bit… off. But history seems to forgive the idiosyncracies of the geniuses, and not so genius among us who come up with innovations.
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.
