The temperature is different from the lumens. Temperature refers to the color quality of the light, whereas lumens is the actual brightness.

The reason whiter lights tend to also be brighter is that making a light that temperature really calls for LEDs. LEDs tend to be brighter than other bulb types.

But as others have pointed out, in car headlights, it has much more to do with the angle and height of the bulb and housing.

  1. describes relation between side lengths in a right angled triangle
  2. a basic rule of logarithms that says the logarithm of a product is equal to sum of the logarithms of the product's factors
  3. the definition of the derivative of a function f at the point t
  4. the formula used in classic physics to describe the amount of gravitational force between masses m1 and m2
  5. the definition of i as the square root of minus one
  6. the relation between the number of vertices, edges and faces in polyhydra
  7. the probability distribution for real valued random variables (bell curve)
  8. a criteria that u has to meet in order to be a wave function (like sin or cos)
  9. a possibility do approximate a function by overlapping wavefunctions
  10. describes a fluids motion (flow)
  11. a collection of formulas describing properties of magnetic and electric fields (to me this the most impressing one as it somehow has the speed of light in it - in 1865.)
  12. an axiom in thermodynamics stating that the entropy of an isolated system is only getting bigger or staying the same, but never gets smaller
  13. the energy of resting masses stating that mass is "a form of" energy. (There should actually be more parts to this equation as a mass can also be moving, be hot etc. I guess this short version just looks more pretty)
  14. "describes the motion of particles in quantum mechanics" - by u/NoOne-AtAll
  15. "The "Information Theory" equation is entropy (...) Basically tells us the bits we need to encode events, very important for computers & the internet." - u/Liorogamer
  16. "(...) describes a sequence where small changes to the starting value are dramatically and unpredictably amplified as the sequence progresses." - by u/jackeddie04
  17. "(...) allows you to accurately value a time limited contract to buy/sell an equity at value X for the length of the contract." - by u/someotherstufforhmm

last three I do not know - only that the last one has something to do with money. Maybe someone can help here. Or you can just google it.

Edit: Thanks for the positive response. I am no proper mathematician or physicist. If you spot something that is not well described, let me know.

Maybe! But my being right about something and my being biased aren't necessarily related. Maybe especially in my field.

I have a MDiv, a Masters in Divinity from a seminary and I am working as an Episcopal priest. Without even delving into the metaphysical, you and I could be disagreeing about history, what a certain writer's position was, maybe etymology. I almost certainly know more about those things than most people. And my believing that I know more about those things than most people is bias that might blind me to something in an argument.

Comparing that to the Dunning Kruger effect, someone with no training in theology might falsely assume they're an expert because they're a lifelong practicing adherent in their religion. But if that person and I disagree I might also falsely assume that I am just correct about something because I happen to have been to a lot of school for it.

I could be wrong about this infographic though. I have no training in cognitive bias, though I do own one of those little Oxford very brief introductions to it. And I think that the bias itself is decoupled from whether or not we are actually correct.
