The lie of algebra

Postby brittonie » Tue Feb 14, 2012 12:24 am

1/3 is a symbol for a set of 4 words, it is not a NUMBER.

Only a single number CAN POSSIBLY = 1. Other numbers may ADD UP to 1, but they don't EQUAL 1. Since 1 clearly = 1, .99999 repeating simply cannot equal 1.

.33(repeting) is irrational.

.99999 does not equal 1. It might in the CURRENT UNDERSTANDING of mathematics, but that don't make it true.

Mathematics cannot even prove that .99999 ... is not equal to 1.

Right now, math really can't deal with infinite numbers

.9 repeating, an irrational number, is ABSOLUTELY EQUAL to the rational number 1. Can this be used as proof to show there is no such thing as irrational numbers?

I'm half tempted to say there isn't really a right or wrong answer

I think I've come to the conclusion that .999... = 1 in the same sense that .333... = 1/3. Which is to say, it doesn't, quite, but we treat it like it does because our decimal system has problems.

0.9 recurring does not equal 1. Why? Because it's 0.9 recurring.

1 = .9 repeating IF WE WANT IT TO.

so does that make 2.999 mean <3 or =3 ?

it's very irrational and so unattainably specific- gah.

it's a love note- see last year's
a little less complex

but here's another interesting thing:

1= 1/2 + log2Hav -> formula for calculating Tsunami intensity


The first scale that genuinely calculated a magnitude for a tsunami, rather than an intensity at a particular location was the ML scale proposed by Murty & Loomis based on the potential energy. Difficulties in calculating the potential energy of the tsunami mean that this scale is rarely used. Abe introduced the tsunami magnitude scale Mt, calculated from,
Mt= a log h + b log R =D

where h is the maximum tsunami-wave amplitude (in m) measured by a tide gauge at a distance R from the epicenter, a, b & D are constants used to make the Mt scale match as closely as possible with the moment magnitude scale.

But that maths is unable to comprehend love doesn't mean maths is unable to comprehend maths, and you don't need to argue the former in order to demonstrate the latter.

Or, to put it another way, infinity is one of the things I love and get excited about, so I can't help talking about it if I get the chance.

i should have wrote some stuff with last year's valentine then maybe the intended would have responded, and i would have known they read it.
now i know :)

- To be perfectly honest i just copied and pasted a bunch of maths quotes that related to both the xkcd as well as the semi private joke i have going on which is continued from last year....

i intentionally posted it in technology for the purpose of drawing the attention of someone... though i know it would have been seen regardless, i figured a post in technology, esp. by me, would have drawn more special attention.

so anyway.

yes.
i'm just publicly flaunting a private thing because i'm obnoxious like that.
Happy VD.
xoxxo to all of you and
<3 to 1

Sounds a lot like the zen maths of Douglas Hofstadter in his book Godel, Escher, Bach. Now there's an afternoon or three's reading.
