| 1371571 | 2014-03-29 20:57:00 | What does this symbol mean in maths? ≈ I should know the answer having got nothing less than A+ in my maths papers at uni, but buggered if I can remember it ... living beyond my expected years does have its drawbacks!!! :o |

| 1371574 | 2014-03-29 21:30:00 | Close enough that for most intents and purposes it is the same, but when you get right down to it, it isn't. | Agent_24 (57) | ||
| 1371575 | 2014-03-30 01:29:00 | It means identical, but not as quite identical as our deluxe model, available at extra cost. ;) | R2x1 (4628) | ||
| 1371576 | 2014-03-30 02:15:00 | Close enough that for most intents and purposes it is the same, but when you get right down to it, it isn't. Yep. I can't imagine maths (usually such a precise thing) having such a symbol. Husbands first ever bathroom DIY, he ≈ two wall panels. That's why we ended up with a join/patched on bit in one of them ever after.... |

Builders - hey this beam is ≈ to the other one......right. Well. you've really answered your own question, this is where maths meets the physical world of impreciseness and approximation. What is much more amazing is how well the abstract but precise world of mathematics is able to describe and model the real world. |

| 1371579 | 2014-03-30 06:43:00 | 22/7 ≈ pi. ;) Actually 22/7 does = pi. Where the difficulty lies is converting the fraction to decimal. Thus 3.14159 ≈ pi. Damn I'm boring. Soz. :D |

| 1371580 | 2014-03-30 07:28:00 | Actually 22/7 does = pi. Where the difficulty lies is converting the fraction to decimal. 22/7 > pi, there have been multiple proofs of this. @pctek - if the two beams differ in length by 3 microns, then technically they would be approximately equal, but the difference is so minuscule as to be effectively zero. |
