The document discusses an experiment to determine if color and hardness are correlated properties of electrons. Electrons are sent through a "color box" and "hardness box" with apparatuses to measure white or black, and hard or soft respectively. The results show that color and hardness are independent, as electrons measured as white had a 50% chance of being measured as hard or soft afterwards, and vice versa. Further experiments complicate the results and suggest color and hardness are not persistent properties, and some other unmeasured property may determine the measurement outcomes.
Does white determine hardness
- 1. DoesWhite determine Hardness?Sowe cananswerthisquestionbyusingourboxes So letssendinsome randomelectrons,andletssendthemintoacolorbox,and letstake the electrons that come out the white apparature So I am goingto take a piece of metal,scrape off some electrons,andthensendthemin Theycome out about 遜 and遜, and I take those that come out the white apparature I wantto knowdoes-whitedeterminehardness?andIcan do that-bysendingthe whiteelectronsinto the hardness box-andseeingwhatcomesout
- 2. ThenI will findthat50% come onhard and 50% come out soft
- 3. Andnow letstake the situationandreverse this
- 4. You will againget50/50 So if youtake a white electronandsenditina hardnessbox youare at evenodds Lllllllllllllllllllllllll
- 5. AndIf I senda softelectronintoacolor box- youare still atevenodds
- 6. Anyquestions So knowthat the colordoesnot give youanyinformationaboutthe hardnessandthe hardnessdoesnot give youany informationabout the color
- 7. Theyare independentfactsandindependentproperties-theyare notcorrelated-inpreciselythis operational sense-cool -questions Llllll So now we say that nowthese propertiesare uncorrelated
- 8. So-now-whatwe are gonnadoisrun so pseudoexperiments whichwill leadustosome more complicatedexperiments So forexample-take thislastexperiment-take electonsintocolorbox comingoutthe white apparature (some one behindyou) The sendintoa Hardnessbox-thensendthe softelectronintoacolorbox Andwhat doyou expecttohappen- Well letsthinkaboutthe logichere-anythingintothe hardsbox-mustbe measuredtobe white Andwe just didthe experimentthatif we sendthe electronintothe hardnessbox 50% itcomesout the hard apparature and 50% incomesout the softapparature
- 9. Since colorsare repeatable-ourprediction-isthatof the electronsthatare incidentuponthe colorbox- 100% will come outwhite and0% shouldcome outblack Exceptthat classis all wrong We saidalreadyknowingthe colordoesnotpredictthe hardness-butthiselectron whichwas previouslymeasuredtobe white-issubsequentlymeasuredandsometimesitcomesoutwhite sometimesitcomesoutblack- 50/50 percentof the time What that tellsyouisthat youcan not thinkof an electronthatis blackand softwrittenonit- because apparentlythatblackandsoft Is nota persistentthing Meaningthat once it isblack itstays black-sowhatisgoingon here?
