What is Numberphile?
Numberphile is an educational YouTube channel featuring videos that explore topics from a variety of fields of mathematics.
Why is the number e named e?
So I’m sure you have all heard of the number e which is approximately 2.71828… . But why is it called e? It isn’t due to Leonhard Euler, since he didn’t name the number after himself, the first letter of his last name being just a coincidence. So, why is it called e? Euler was the first to name the constant “e”.
What is meant by base in math?
The word “base” in mathematics is used to refer to a particular mathematical object that is used as a building block. The most common uses are the related concepts of the number system whose digits are used to represent numbers and the number system in which logarithms are defined.
What’s the last number in the world?
A googol is the large number 10100. In decimal notation, it is written as the digit 1 followed by one hundred zeroes: 10,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000.
Who does Numberphile?
journalist Brady Haran
Numberphile is produced by video journalist Brady Haran. The stars of the show include mathematicians and other guests from around the world. Topics range from the sublime to the ridiculous… from historic discoveries to latest breakthroughs.
Why do we count in base 10?
The base 10 system allows for simple explanations of hundred tens and units etc. Using a base two system such as the Arara tribe in the Amazon would get very repetitive and confusing rather quickly but on the other hand using a base 60 system it would take a long time until you exchange it for another to start again.
Can numbers end?
The sequence of natural numbers never ends, and is infinite. OK, 1/3 is a finite number (it is not infinite). There’s no reason why the 3s should ever stop: they repeat infinitely. So, when we see a number like “0.999…” (i.e. a decimal number with an infinite series of 9s), there is no end to the number of 9s.
What numbers would look best in base 8?
All those numbers would look great in Base 8. A really messy one like 37/64, which is .578125 in decimal notation, works out to a slim and trim .45 in octal notation. A nice side benefit of Base 8 is that the multiplication table is 64% as big as the Base 10 multiplication table. The same is true of the addition table.
The New York Times has said, “At Numberphile, mathematicians discourse, enthusiastically and winningly, on numbers”. The channel has featured mathematicians, computer scientists, scientists, and science writers, including:
What are the advantages of base 8?
A nice side benefit of Base 8 is that the multiplication table is 64% as big as the Base 10 multiplication table. The same is true of the addition table. So arithmetic would be that much easier for everybody.
How many base 8 numbers can you take a stab at?
You can only take a stab at the .1, .2, .3, .4, .6, .7, .8, or .9 spots. Yes, you can nail the numbers that occur naturally in Base 8, such as 1/2 (.5), and multiples of 1/4 (.25), 1/8 (.125), etc., but just those few.
