Why do ovens have a button for toggling the internal light off and on? If the oven is on, the light should be on. If the oven is off, the light should be off. Simple. #TheDesignOfEverydayThings #FoodieUX

@cleverdevil Say you wanted to use the light to raise the temperature just a little to nurture your sourdough leaven ???

@jeremycherfas sounds like an edge case to me ;)

@cleverdevil in a college physics class I had to determine the difference in bake time with and without the light on.

@cleverdevil why use more, even a bit of electricity then needed? Would love to know...has to add a mimnimal fraction of heat

@cleverdevil I mean, it was technically faster with the light on...but by a completely negligible amount. The math also didn’t take into account energy usage, and I bet it’d be a wash if you did because most appliances are limited to how much power they can draw.

@jgmac1106 the heat and electricity are so minimal, I think it’s worth it.

@cleverdevil I thought it was all about edge cases.
