Quote from: Ray on June 06, 2015, 08:20:25 amIn certain branches of science, great accuracy is required. An example would be the design and construction of a digital camera sensor.There are degrees of accuracy, just as there are degrees of heat, or temperature.

Quote from: Rob B. on June 06, 2015, 04:13:59 am... If people do not feel what you intend for them to feel; if they do not see what you intend for them to see, what should one conclude?
Quote from: stamper on June 06, 2015, 05:54:28 am... There are dozens of threads on here alone disputing the fact that photography is mostly not an accurate representation of reality.
Quote from: stamper on June 06, 2015, 07:01:20 amRay you are now dancing on the head of a pin. Difficult for someone your age?
Quote from: BartvanderWolf on June 06, 2015, 07:51:44 amA number may be very precise, e.g. 3.00153001, but it not very accurate if we meant it to represent the mathematical constant 'pi'
Quote from: Manoli on June 06, 2015, 08:46:43 amIn that context, the word you're looking for is 'precision' not accuracy.You need to differentiate between the definition and usage of accurate , exact and precise.You may aim a gun accurately but you would manufacture a sensor with precision.There are no degrees of accuracy, there are degrees of error - entirely different and in turn different from degrees of heat and temperature.
Quote from: ripgriffith on June 06, 2015, 10:44:08 amI have now reached boredom overload, precisely and accurate the point at which I leave this thread.
Quote from: BartvanderWolf on June 06, 2015, 08:52:27 amSomething can be accurate, or more accurate, or inaccurate (3.14 is an accurate approximation of 'pi', 3.1415 is more accurate, 3.1416 is even more accurate, 3 is less accurate, due to differing precision. Then 10 is even so much less accurate that it rather deserves the term approximate (if even that), unless you are describing the number 'ten', and not 'pi'.
QuoteBTW, degrees of heat can be expressed in Celsius, or Kelvin, or Fahrenheit, or ..., either precisely or not.
Quote from: Ray on June 06, 2015, 11:14:34 amThe words accurate and precise are synonyms.
Quote from: Ray on June 06, 2015, 11:47:39 amWhat might be considered as precise for one purpose could be considered imprecise for a different purpose which requires higher standards.
Quote from: Ray on June 06, 2015, 11:14:34 amThe words accurate and precise are synonyms. However, I prefer the word accurate within the context of photography because the etymology of 'accurate' is from the Latin 'accuratus' which means 'done with care'. When I take photos and process them, I do so with care.The etymology of 'precise' is from the Latin 'praecis' meaning 'to cut short'. I try to avoid cutting my photos short.If there are no degrees of accuracy, then there is only one state of perfect accuracy, which is of course a nonsense. All degrees of error are in relation to a particular standard of accuracy, and those standards of accuracy vary according to the circumstances or the context.
Quote...there is a mismatch between intention and perception. A failure, in other words.
QuoteShould one conclude?
Quote from: Rob B. on June 06, 2015, 01:19:03 pmHow should Nancy evaluate success from the questions you suggest she asks?
Quote from: Rob B. on June 06, 2015, 12:05:47 pm... A failure on whose part?
Quote from: BartvanderWolf on June 06, 2015, 11:55:42 amNot in science.
