  1. Will says:

    how do we go from “is the sun bigger than the moon?” to “explain quantum physics”…? 😐

  2. Pixel says:

    Mostly it’s a side effect of me going from pessimistic to optimistic and from excited to weary.

    You should have seen the first draft. The final question was: “Why is Adam Smith’s invisible hand touching me?”

  3. Anon says:

    Forgive my sounding like a jerk, please, but you can’t be serious.
    If you claim to know the answers to all of these questions, you are incredibly arrogant and deluded.

    “What is a black hole?” Really? You know? Publish!

    “What do Muslims/Christians/Hindus/etc believe?” You think that they all believe the same thing?

    “What is gravity?” What is a force? Please tell us.

    “Explain quantum theory” Wow. This just shows your ignorace.

    I’m sure you get the idea. Give me a break.
    And you clearly need to do some reading on metaphysics–you don’t know what “is” means. Get rid of this list and start back there–look up “ontology”.

  4. Pixel says:

    My response will be up at 4 a.m. GMT. Please stay tuned. 🙄

  5. Ashley says:

    I may not be able to brilliantly explain the answers to all of those, but I do have a pretty good idea. I’m a smart person.

    Also, look, Pix! You have your very own asshole, anonymous harasser just like mine!

    To Anonymous Jerk: I believe that you entirely missed the point of this post.

  6. Ashley says:

    But also, FYI, science isn’t the only thing that matters, dude. I should make my own list of things that everybody should know. It would look VERY different from yours.

  7. courtney says:

    I don’t know many of the exact answers, but I do have enough of an understanding of the subjects you brought up to be able to quickly find the answer, in most cases. Some people have extremely freakish memories and they remember everything they’ve ever been taught (like my dad. what a freak.) but not everyone is like that. I think the real purpose of education is not to teach facts, but to help us learn to find answers when we need them. Looking at your list, I think I’ve realized my education has been fairly sound.

    Obviously these questions would depend on your culture, but use of language should definitely be on that list somewhere. Grammar, ability to write well, speak well, etc. I don’t know how you’d put that in list form, but I think it’s necessary.

  8. Pixel says:

    Aw, Thanks. You rock. And please: Memeize me. I know my list is flawed, but I can’t figure out a great way to change it. Perhaps your list can show me the light.

    That’s actually all I wanted. I think most people should have a general idea of the items on this list as part of their primary education. I didn’t think about the language, but I agree that there should be more history and perhaps some social and cultural questions. I go a little science heavy because it’s easier to frame those sorts of questions.

    p.s. According to my stats page, you’re now the ninth most prolific commenter on my blog. Congratulations.
