Hey, Silvia, did you catch the part about irrational numbers in today's math lecture? |
|
|
Yeah, I did, Murphy. As far as I understood, they're numbers that c an't be expressed as fractions. The decimal representation goes on forever without repeating. |
|
|
That's correct. Like that square root of 2 example the professor mentioned. If you try to express the quare root of 2 as a fraction, you can't It's an irrational number. |

For me, it was so interesting how Pythagoras and his followers encountered it for the first time. |
|
|
Yeah, they were trying to find the length of the hypotenuse in a right- angled triangle with legs of length 1 and shocked to discover that the square root of 2 couldn't be expressed as a fraction of two integers. This was a groundbreaking revelation! |
