    A Geometric Product (a series of exercises for the curious)

    I hope you have fun with these... OK, so you know the geometric series, right? It goes like this: \sum_{k=0}^{\infty} z^k = \frac{1}{1-z},\forall z\in\mathbb{C}\mbox{ such that }\left| z\right|<1 How about this one? Call it, say, the geometric product: \prod_{k=0}^{\infty} \left( 1+...

    Curious statement about operators in my QM book?

    hi, In a discussion of the historical motivations for a move from calculus to operators, my QM book says... "Many mathematicians were uncomfortable with the 'metaphysical implications' of a mathematics formulated in terms of infinitesimal quantities (like dx). This disquiet was the stimulus...

    The Curious Case of Hair Growth: Evo & Physiological Reasons

    Why does the hair on our bodies (much like the hair on animals) grow to a certain point, then fall out/stop, but the hair on our heads seems to grow indefinately? Do any other wild animals have hair that can grow forever? I'm not only interested in why it grows in physical terms, but...

    Curious questions about a pendulum

    If the size of the ball that is attached to the pendulum increases, will it affect the swing at all? What if you changed the mass of the spring, will that influence any change in T? Also, why is that an iron bob is more suited than an aluminum?

    Exploring Differentiation and Integration Techniques for Trigonometric Functions

    Yo. Curious about two things.. First, is it possible to use a method such as differentiation from first principles (the whole lim_{\delta\rightarrow0}\[f(x+\delta)-f(x)]/\delta thing) to differentiate trigonometric functions? Or is everyone stumped with memorizing them? (I'm curious about...

    Curious question about Magnets

    When playing around with magnets, one can notice that they attract objects from a distance. No only that, but they can also attract quite heavy objects many, many times in a row. Where does the energy that moves the objects come from/stored? Does it ever "run out"? My guess is that magnets...

    Can a Linear Operator Define This Specific Polynomial Transformation?

    Well, this problem is kinda dumb; it's in the GIF image file that I attached... a,b,c,d,...,z are all real constants, and 'n' is natural; I was wondering if such a function would exist...for the real constants a,b,c,d,...,z (filename is polyprobgif.gif and sumformul.gif)

    A Curious Question About Freezing

    Here's a question I've been thinking about for a while; maybe you guys could provide some guidance. If the air temperature is below 0 degrees Celsius, the water at the surface freezes to form ice, right. Now the question I have is: why doesn't freezing occur throughout the entire volume of...

    A curious function in quantum gravity

    quantum gravity research seems to be undergoing some changes so just because this function comes up today doesn't mean it will be around for eternity, but that said, look at this function L(x) = \sum_{p = semi-integer > 0}\frac{1}{x^\sqrt{p(p+1)}} It comes up in connection with Black...

    Discovering a Simple Inequality for Divisor Count in Positive Integers

    I know that this isn’t very practical but I discovered the following curious inequality when I was playing around with d(n) where d(n) gives the number of divisors of n \ \epsilon \ N. If n has p prime factors (doesn’t have to be distinct prime factors e.g. 12 = 2^2 \ 3 has got three prime...

    The TOE: Does It Explain Everything?

    The TOE should explain EVERYTHING. We may not know what it is, but if it does indeed explain everything, odds are that we already possesses a formula which describes a very commonplace phenomenon of physics, but have not yet recognized the universality of that phenomenon.
