Vacuuming Nickels via Semantic Mining?

<t>It seems to me that we can view the financial markets as our collective global mind applied to the valuation of companies, derivatives, etc. Another obvious example of our global mind at work is the internet -- in particular blogs and forums such as this one. Obviously there is a lot of informati...

Impending Ice Age - What We Can Do (Mitigation)

<t>Heheh pumping sulfur dioxide into the stratosphere to blot out the sun, what could possibly go wrong? I think this idea was first proposed by a protege of Edward "Dr. Strangelove" Teller. I agree it sounds nuts, but if we're going to be a successful global species we're probably going to have to ...

Impending Ice Age - What We Can Do (Mitigation)

<t>That's a nice idea, but good luck rocketing your monkey ass across the galaxy in a nuclear powered tin can. Now if your intelligence could be abstracted onto a different substrate, space travel could become a matter of beaming yourself at the speed of light via electromagnetic waves. Personally I...

Martingale Problem

<t>Here's a problem that seems simple but I'm struggling with it:Let Y_k be the number of times a simple symmetric RW hits 0 before hitting k for the first time.Prove that Y_k - 2*k is a martingale wrt a suitable filtration.I.e. we need to show that E(Y_(k+1) - 2*(k+1) | F_k) = Y_k - 2*k, i.e. E(Y_(...

Impending Ice Age - What We Can Do (Mitigation)

<r>I find it interesting that if you study the predictions of the climate change/population modelers, the peak oilers, the Singularitarians and Didier Sornette's theory of bubbles (see <URL url="http://arxiv.org/abs/cond-mat/0002075">http://arxiv.org/abs/cond-mat/0002075</URL>), they all give approx...

Dragon-Kings, Black Swans and the Prediction of Crises

<t>Sornette's ideas are interesting, but I need to see some mathematical models. Can anyone summarize his "dragon kings" theory or theory of bubbles in equations? The graphs are nice, but it mostly seems like hand waving without some math. The other obvious question is, if Sornette's theories work w...

Some Random Questions about Science, Finance and the Robot Apocalypse

<t>Is the scientific method being transformed by massive computational capacity into an inductive, rather than deductive process? To use quantitative finance as an example, is the field evolving toward pure statistical data crunching rather than the more traditional "rocket science" modeling via equ...

Gaza

<t>The bigger picture here, as I see it, is this: the West is once again in a life and death struggle against militant Islam, and needs all the allies it can get. Hamas is part of a larger medieval theocratic movement that seeks to destroy the western way of life and impose Sharia law. Some hard cho...

how "safe" is a career in quant. fin. right now?

<t>My advice is to forget about employment going forward and start building a bunker now that can support you and your loved ones without contact with external civilization for several years. This will not only allow you to survive most apocalyptic scenarios (social collapse, global warming, asteroi...

Thrones

<t>Heh you're welcome. Three is about what I figured off the top of my head. As a side note, I'm starting to think that intuition, common sense and the ability to make simple back of the envelope calculations is all you really need in the financial world. This is why I would think physicists would b...
