We have two urns, A and B, with Urn A containing 2 blue balls and 1 red ball, and Urn B containing 1 blue ball and 2 red balls.

The following experiment is conducted to a group of people.

We randomly select a urn, and let participants guess which urn (A or B) it is without seeing inside the urn.

Scenario I: One by one, each participant draw a ball from the urn, check the color without showing to other participants, guess which urn it is, and put the ball back to the urn.

Scenario II: One by one, each participant draw a ball from the urn, check the color, but this time show it to other participants, guess which urn it is, and put the ball back to the urn.

So, the question to answer are:

Which scenario leads to more accurate individual predictions?

Which scenario leads to more accurate combined predictions?

After 3 days of head scratching, I think it is time to roll the ball. I am 100% certain that after 3 months, I would be switching to twitter bootstrap(x.x), so why don’t I bother worrying about how to add a side bar or how to fix the head bar. After all, the most important thing for a blog is the content, without it, layouts are nothing special.

So, get it rolling!

Let us see if d3.js works in Markdown, this is a reproduction of the d3.js example Voronoi-based point picker

It works like a charm!

I would like to try some of the simple latex format in markdown, I came to know there are some limitations, but let’s see. let us try some $\LaTeX$, see what happens $a^2 + b^2 = c^2$

and

$\frac{d}{dx}\left( \int_{0}^{x} f(u)\,du\right)=f(x)$
