I just realized while cooking that a measuring-cup cup (as measured out as 250mL in a glass measuring cup) is the same amount(s) as one of the actual plastic baking measuring cups that go inside each other like Russian dolls lol

I thought they were different somehow (something something imperial metric yadda yadda yaddda)

Your turn to come clean Lemmings!

**EDIT: to clarify, I mean volumetrically for measuring liquids

    Definitely yes. I’m amazed (but not surprised) by the lack of understanding of this concept.

    I suggest that everyone here play around with mirrors and learn something themselves.

    I’ll leave you with this. Why do mirrors work to see around corners when you are trying to not be seen?

    This might help explain things.

      That link shows that Mario would see your eyes in the mirror. Those light rays work in both directions. If you can see Mario’s eyes, Mario’s eyes can see yours. This is clearly shown in that link.

      People use mirrors to covertly look around corners because the mirrors they use are smaller than their head. And if the mirror is still spotted getting a bullet in the mirror is much less lethal than getting a bullet in the head. It has nothing to do with the mirror somehow being magically invisible to whoever is around the corner.

      You are wildly misunderstanding the effect at play. All this says is peoples brains are inherently misinterpreting the angles

          You can see other people in a reflection without them being able to see you.

          It is not possible to see someone else’s eyes (except from the side, so it’s only seeing their eyes in profile) in a reflection without them being able to see you too.

          It’s literally not possible via reflection, as everything is equal and opposite. If light can go from their eyes to yours, it’s also possible to go the opposite direction.

          This is what everyone has been saying but instead of thinking through everything clearly, you resorted to bullying.

          The only way to accomplish this one-way vision is by adding something that is not reflection to the system (like a one-way window), but that’s breaking the premise under which everyone else has been commenting in good faith.

              Dude, calm down. It’s just a discussion. Just give us an example of how I could see somebody’s eyes in a mirror without them seeing my eyes and we’ll all be amazed at how you were right all along.
