    Help me Prove that such a set does NOT exist

    This is what I have so far, but I have no idea if it's anywhere close to correct and I have like 4 chapters of my textbook that I need to cover the relevant materiel. My intuition is that either I have to show some sort of overlap between R and R-completment, or that I have to show that the...

    Help me Prove that such a set does NOT exist

    Let Q denote the theory of Robinson Arithmetic. A theory T is nice iff T is consistent, is p.r. adequate and extends Q. The fixed-point lemma states that for all nice theories T, for any formula φ, there is a sentence σ such that T ⊢σ↔φ("σ")...

    What topics should I review before taking Gen Chem 2?

    Well I don't really have too much difficulty with math or physics. Are there any concepts specific to chemistry you think I should know? If it helps this is the description of the first semester course from my school: Includes the study of atomic structure, nomenclature, chemical reactions and...

    What topics should I review before taking Gen Chem 2?

    I'm planning on taking a second semester general chemistry course in the spring, and I'm wondering what I should study before hand. Based on RateMyProfessor, my teacher is going to be super hard. I took the first semester general chemistry course and I got an A in it, but that was last fall...

    Books on Interpretations of Quantum Mechanics

    This one French physicist Bernard D'Espagnat wrote an interesting book which covers a lot of this material in depth called On Physics and Philosophy. In it he's putting forth his own interpretation, so he does confront and criticize all the other popular interpretations, but he still presents an...

    What went wrong in evaluating this integral?

    What did I do wrong evaluating this integral: ∫ [4 / (4x^2 + 4x + 65) dx ? Here were my steps: 1) = 4 ∫ [1 / (4x^2 + 4x + 65)] dx 2) = 4 ∫ [1 / (4x^2 + 4x + 1 + 64)] dx 3) = 4 ∫ [1 / ((2x+1)^2 + 64)] dx ; Then I applied the formula: ∫ [1 / √(a^2 + u^2)] dx = (1/a)arctan(u/a) + C; 4) =...
