I think we can do without the whole notion of truth and reality.The traditional notion of truth is that a statement is true iff there some "correspondences" between the statement in question and reality. An attack on this conception of truth is a either/and attack on: 1) The notion of...

Homework Statement Let X be a metric space, with metric d. Fix a point a in X. Assign to each p in X the function f_p defined by f_p(x) = d(x,p)-d(x,a) where x in X. Prove that |f_p(x)|\leq d(a,p) for all x in X, and that therefore, f_p in C(X). Prove that ||f_p-f_q|| = d(p,q) for all...

I'm having problems taking a stab at this question: Find a formula for the number of edges in Kn. What happens to the ratio of edges to verticies as n increases? Formula: n/2 * (n-1) Ratio: this is the part I can't figure out. I assumed the ration is n/(n/2*(n-1)) Give a brief verbal...

Hi, As it stands, I am borderline clueless when it comes to mathematics. I had bad teachers in school and so was pretty much doomed from the offset. Anyway, I have recently developed an interest in learning more and improving my abilities but am having a thoroughly frustrating problem that...

This is an interesting statistic I read recently... apparently, in 500 million years the atmospheric CO2 will have been vastly depleted due to it reacting with silicon and being stored underground. The CO2 levels will then be too low to allow photosynthesis to occur. This statistic, presumably...

Hi, I have an assignment where I must graph various trig functions and the instructions say to graph each for a complete cycle. Does a complete cycle mean until the graph begins to repeat so for instance a complete cycle for a sin graph would be from the range 0 to 2 pi? Thanks for any help.

I need my computer to be restored to the way it was when I first bought it. I have a Dell with Windows XP on it, and I've already tried the system restore where it goes back to settings on a specific date, but that didn't help the situation. I can't even get on the Internet now. How do you run...

[SOLVED] Discrete Math - Complete set of representatives Homework Statement At what temperature fahrenheit is it equal to celsius? Homework Equations (none) The Attempt at a Solution

Suppose we did (for the first time) have a TOE that theoretically predicts all the experimental results to date on all sclaes of size. However two things are still in question: 1. How accuately does it predict everything (that have been experimentally carried thus far) at all scales? 2. How...

Hello, My name is Joe and I am a junior in high school. I am taking AP Calculus right now along with a basic physics class. I am very, very interested in the special and general theories of relativity, but I want to know the exact logic behind it. Right now, I don't really understand any of...

this isn't really a homework problem it's just me trying to understand a part of an example problem from a modern physics book it's an integral of a wave packet, blah blah blah but they go on to say "...to evaluate the integral, we first complete the square in the exponent as..." ikx -...

What for do we need operators in QM. Where is the complete state description of a quantum object?

In the creation/annihilation operator picture the Hilbert state of a quantum harmonic oscillator is spanned by the eigenstates |n> of the number operator. I've never seen a proof that: 1. the ground state |0> is unique 2. the states |n> form a complete basis i.e. any state in that Hilbert...

Homework Statement What are some ways to show that a space is complete? It is tricky because to show completeness, must show every Cauchy sequence converges to a point in the space. The Attempt at a Solution One way is by contradiction? Suppose that there exists a Cauchy sequence that...

Let's have a look at \left\{ \neg,\equiv\right\}. How could one show that this isn't complete? I've tried finding some sort of invariance that propositions built with these might have, but I couldn't find anything... I'm going crazy! :smile:

Can anyone recommand a simple but complete mathematical methods book written especially for undergrad physics students?
