Did Einstein discover the Rule of 72?
The Rule of 72 explains the miracle of compounding interest.
It is alleged that Albert Einstein referred to compound interest as the “most powerful force in the universe” or the “greatest mathematical discovery.” However, no proof can be found that Einstein ever mentioned the Rule of 72, much less invented it.
Instead of needing to double your capacity in 36 years, you only have 24. Twelve years were shaved off your schedule with one percentage point faster growth. The Rule of 72 was originally discovered by Italian mathematician Bartolomeo de Pacioli (1446-1517).
Some inventions and contributions of Einstein are Avogadro's Number, Quantum Theory of Light, General Theory of Relativity, Special Theory of Relativity, The Photoelectric Effect, Wave-Particle Duality, Brownian movement, the relationship between mass and energy, Bose-Einstein Condensate, and many more.
According to Einstein, “Compound interest is the eighth wonder of the world. He who understands it, earns it … he who doesn't … pays it.” At first this quote might seem like a bit of an exaggeration but the math behind it shows that it is not.
The first reference we have of the Rule of 72 comes from Luca Pacioli, a renowned Italian mathematician. He mentions the rule in his 1494 book Summa de arithmetica, geometria, proportioni et proportionalita (“Summary of Arithmetic, Geometry, Proportions, and Proportionality”).
Roughly translated: In wanting to know of any capital, at a given yearly percentage, in how many years it will double adding the interest to the capital, keep as a rule [the number] 72 in mind, which you will always divide by the interest, and what results, in that many years it will be doubled.
The Rule of 72 is reasonably accurate for low rates of return. The chart below compares the numbers given by the Rule of 72 and the actual number of years it takes an investment to double. Notice that although it gives an estimate, the Rule of 72 is less precise as rates of return increase.
40% of your income goes towards your savings. 30% of your income goes towards necessary expenses (food, rent, bills, etc.). 20% of your income goes towards discretionary spending (entertainment, travel, etc.). 10% of your income goes towards contributory activities (donations, charity, tithe, etc.).
The Rule of 69 is a simple calculation to estimate the time needed for an investment to double if you know the interest rate and if the interest is compound. For example, if a real estate investor can earn twenty percent on an investment, they divide 69 by the 20 percent return and add 0.35 to the result.
I begin the discussion by offering the following three laws: ▸ The laws of physics are identical in all non-accelerating (that is, inertial) frames. ▸ The vacuum speed of light, c, is the same for all inertial frames. ▸ The total energy E of a body of mass m and momentum p is given by E=√m2c4+p2c2.
What was Einstein's IQ?
His performance beats those of physicists Stephen Hawking and Albert Einstein, who were both estimated to have IQs around 160.
He received the 1921 Nobel Prize in Physics for his discovery of the law of the photoelectric effect and his work in theoretical physics.

The Ninth Wonder of the World is any library's stacks, it's collection. Wonder, in it's most basic senses means something that causes astonishment or admiration, or being in a state of astonishment or admiration. That's what library's stacks offer any time you visit. Wonders are more often discovered than sought.
Fortunately, the rule of 78 was outlawed nationally starting in 1992 for loans that last longer than 61 months, though it might still not apply in every state regardless of the loan term.
One of the most common percentage-based budgets is the 50/30/20 rule. The idea is to divide your income into three categories, spending 50% on needs, 30% on wants, and 20% on savings. Learn more about the 50/30/20 budget rule and if it's right for you.
With an estimated annual return of 7%, you'd divide 72 by 7 to see that your investment will double every 10.29 years.
One of the most famous and well-known equations in all of human history, E = mc^2, translates to "energy is equal to mass times the speed of light squared." In other words, wrote PBS Nova, energy (E) and mass (m) are interchangeable.
ABOUT THE DESIGN ALBERT EINSTEIN -"THE DIFFERENCE BETWEEN GENIUS AND STUPIDITY IS THAT GENIUS HAS ITS LIMITS"-The quote serves as a hard work and effort has to be put to be successful and make a meaning out of it.
What did Einstein say to Nikola Tesla?
Answer and Explanation: Many sources report that, when asked how it felt to be the smartest man in the world, Albert Einstein said, 'I don't know, you'll have to ask Nikola Tesla. ' There is no documentation that Einstein ever made this statement about Tesla. It is almost certain that he never said it.
In finance, the Rule Of 72 is probably used in preference to the Rule Of 70 as 72 has more whole number divisors (72, 36, 24, 18, 12, 9, 8 and 1) than 70 (70, 35, 14, 10, 7 and 1).
In fact, recently, real estate and financial expert Graham Stephan tweeted a quote from Albert Einstein: "Compound interest is the eighth wonder of the world. He who understands it, earns it; he who doesn't, pays it." And you're definitely better off being on the "earns it" side of things.
The so-called Rule of 42 is one example of a philosophy that focuses on a large distribution of holdings, calling for a portfolio to include at least 42 choices while owning only a small amount of most of those choices.
Article Revolution: Energy Einstein's work on the Special Theory of Relativity prompted him to rethink the fundamental laws of physics. He realized that one... Article E=mc2 Scientists long considered energy and mass to be distinct. E=mc2 showed that they're different forms of the same thing.
Albert Einstein, in his theory of special relativity, determined that the laws of physics are the same for all non-accelerating observers, and he showed that the speed of light within a vacuum is the same no matter the speed at which an observer travels, according to Wired (opens in new tab).
His performance beats those of physicists Stephen Hawking and Albert Einstein, who were both estimated to have IQs around 160.
Smarter than Einstein? Albert Einstein likely never took an IQ test but is estimated to have a 160 IQ—but even that can't stand up to these masterminds.
Albert Einstein is best known for his equation E = mc2, which states that energy and mass (matter) are the same thing, just in different forms. He is also known for his discovery of the photoelectric effect, for which he won the Nobel Prize for Physics in 1921.
