fruitbat Posted April 8, 2009 Report Share Posted April 8, 2009 If the ratio between the 2 single numbers is the same ratio as the differnce between the larger number and the sum of both numbers then this is classed as the golden ratio.I think thats the easiest way to explain itFrooty Quote Link to comment Share on other sites More sharing options...

Davetrials Posted April 8, 2009 Author Report Share Posted April 8, 2009 I dont think i was clear enough when i said dumbed down.... im basically trying to understand thisthey noted that objects proportioned according to the golden ratio seemed more attractive. Some modern research seems to confirm this, in that people whose facial features are symmetric and proportioned according the golden ratio are consistently ranked as more attractive than those whose faces are not.

fruitbat Posted April 8, 2009 Report Share Posted April 8, 2009 If you look at the link below on the pyramids bit that makes it make a little bit more sense.If the height was much higher then it wouldn't be in this 'golden ratio' so would look too 'pointy', and much lower would look too flathttp://educ.queensu.ca/~fmc/october2001/GoldenArc.htmFrooty Quote Link to comment Share on other sites More sharing options...
ben_travis Posted April 8, 2009 Report Share Posted April 8, 2009 basically dave - because your facial features are not symmetic and your nose is a wee bitty out of proportion, your not as attractive as i am....thats what its sayingthey noted that objects proportioned according to the golden ratio seemed more attractive. Some modern research seems to confirm this, in that people whose facial features are symmetric and proportioned according the golden ratio are consistently ranked as more attractive than those whose faces are not.

JT! Posted April 8, 2009 Report Share Posted April 8, 2009 I bet you could end up using the golden ratio when composing photography. Quote Link to comment Share on other sites More sharing options...
PaRtZ Posted April 8, 2009 Report Share Posted April 8, 2009 (edited) The fibonacci sequence...you know what that is dave?1,1,2,3,5,8,13,21,34,55,89 etcCall each sequence n=1, n=2, n=3, n=4 etc etc. If you: n=2 / n=1 = 1 Now do: n=3 / n=2 = 2 Keep going: n=4 / n=3 = 1.5 n=5 / n=4 = 1.66666667 n=6 / n=5 = 1.6If you keep going to infinty, the fibonacci sequence converges at the golden mean. IE 1.618Bit more info there for you. Ive got a really cool matlab script I had to write for uni if you want a bit more infoEDIT: Worked a bit more here:x y1 12 23 1.54 1.6666666675 1.66 1.6257 1.6153846158 1.6153846159 1.61904761910 1.618181818 Edited April 8, 2009 by PaRtZ Quote Link to comment Share on other sites More sharing options...
Luke Rainbird Posted April 8, 2009 Report Share Posted April 8, 2009 Ive got a really cool matlab scriptPlease tell me you didn't just say that Quote Link to comment Share on other sites More sharing options...
PaRtZ Posted April 8, 2009 Report Share Posted April 8, 2009 Please tell me you didn't just say that it makes graphs! I actually like matlab once you're used to it. Silly pointless stupid maths questions because a few clicks away, as per real life really... Quote Link to comment Share on other sites More sharing options...

Shaun H Posted April 9, 2009 Report Share Posted April 9, 2009 After Matlab pwned my solid mechanics coursework for me I can no longer hate it with all my heart and have to admit it's pretty useful in the right situation...Does Dave understand this ratio stuff yet?

aener Posted April 9, 2009 Report Share Posted April 9, 2009 (edited) At the risk of sounding patronising....I care not to try and find out why - so I'll say it's for "some reason" - our brain prefers rectangles of a particular proportion. This is 1.618... (phi)It's just a ratio... 1.618:1.Widescreen monitors look nicer 'cause they're closer to this "golden ratio". Square monitors have a ratio of 4:3 (1280x1024 etc...). 4 / 3 gives 1.333 - or 1.333:1.Widescreens have a 16:9 ratio (1680x1050 etc...). 16 / 9 gives 1.777 - or 1.777:1. This is obviously closer to the magical 1.618:1, so our heads prefer it's proportions ("for some reason" )A golden ratio'd screen would be more like 16:10, being that 16.18 inches is getting a bit anal To link this in with the beauty aspect (taken out of proportion for the sake of ease):If your head is an foot wide, if it wasn't close to 1.618 feet tall, you'd start looking a bit weird. (Bottom picture)The other ones are just showing some other relations to phi found on the human face. The more of these that conform on a persons face, the more beautiful they will appear.This picture you were on about the other day is another example.And this can be taken further:The other famous useage of it is in the spiral picture you'll've seen a good few thousand times.This is where the fibonacci sequnce Partz was on about comes in.This occurs everywhere. Nature knows all about it.Most common example is sunflower heads. The seeds grow organised into this spiral.The spiral works in both directions.I sure hope I didn't get it wrong... It's been a while.Interesting stuff though. Search for "Phi". It's the name given to this irational number 1.618....Symbolised by this greek symbol, if you wonder what it all means: Edited April 9, 2009 by aener Quote Link to comment Share on other sites More sharing options...
Luke Rainbird Posted April 9, 2009 Report Share Posted April 9, 2009 Widescreen monitors (PC/laptop, not TVs) tend to be in 16:101440 x 900 etc Quote Link to comment Share on other sites More sharing options...
