Fun With Math And Science

This is just some interesting permutations of 2 + 2 = 5. This is not hacking related, rather, more of \"out of the box\" thinking.

Before you read on, I would like to state:
This article is not hacking related and is really more of an interesting thing to read, hence its placement in "other".

I was reading today a proof for 2 + 2 = 5 and have come up with some fun looking derivatives of it that would make any college math teacher squirm and any college science teacher proud.

2 + 2 = 5 based on significant figures. Since the numbers do not have a trailing period, indicating precision, you can reasonably assume that 2 and 5 are off by a margin of error of within
plus or minus .5.

Therefore 2 + 2 = 5 assuming that 2.5 + 2.5 = 5.
Now, you can also realize that the 5 is mutable in this equation and end with
2.333 + 2.333 = 4.6667. In this case the numbers are only off by 1/3.

To continue on this path and get closer to the actual number, I will bisect 2 into two 1's.
1 + 1 + 1 + 1 = 5, assuming that
1.2 + 1.2 + 1.2 + 1.2 = 4.8.
In this case, we are only off by 1/5.

And finally, the version that will blow any 8 year olds mind and cause a college student to doubt all of his education:

1 + 1 + 1 + 1 = 1 + 1 + 1 + 1 + 1
1.111 + 1.111 + 1.111 + 1.111 = .889 + .889 + .889 + .889 + .889
As you can see four 1's are equal to five 1's.
The numbers in this final case are off only by 1/9, or .11111 repeating. This is a rather good amount of precision allows for the sides to match.

Which made me think of this stuff.
