At a quick glance, most people will say that 1 is larger than 0.99999\ldots

However, consider the following:
Let,
x=0.99999\ldots

Now,
10x = 9.99999\ldots
10x = 9 + x

By a simple algebra, we can find that
x = 1

It means that x=0.99999\ldots=1



Can anyone explain this? Does 0.99999\ldots really equal to 1?

x^2 - x^2 = x^2 - x^2
x(x-x) = (x+x) (x-x)
x = x+x
1x = 2x
1 = 2

One is equal to two?! That's totally absurd.
Can you can spot the mistakes?

The word 'katsu' itself can also be written in a different way as 勝つ, which is read in exactly the same say (a homophone).
Katsu (勝つ) means "to win" or "to gain victory". (e.g. 試合に勝つ!, shiai ni katsu! = I'll win the game!)

This is why Japanese sportsmen eat katsu-don (カツ丼 = a rice bowl topped with deep-fried meat) the day before a big match. Japanese students do the same too before taking big tests or school entrance examinations.

So,, it is OK to say:

A katsu-don (カツ丼 = rice bowl with cutlet) is
a katsu-don (勝つ丼 = winning rice bowl). :D



Do you know that the famous finger-snack Kit-Kat, is called "kitto-katsu (キットカツ)" in Japanese?
Kitto-Katsu, can also be written as きっと勝つ, which means "definitely win!"

Aircrafts that are not fly-worthy anymore, will be stored somewhere in an aircraft bone-yard before being turned into scrap metal. These bone-yards are often referred as graveyard for aircrafts.

The largest aircraft bone-yard located at Davis-Monthan Air Force Base in Tucson, Arizona, USA.
You can even find aircrafts that were used in the Vietnam war.
