## If Christmas wasn’t enough

For those interested, the entire proclamation can be found here.

So, does that mean December 25th is now officially Newton Day?

## Nerd Sniping

From xkcd,

So, how does one find the effective resistance?

The solution to this question, and many other network shapes, is present in Jozsef Cserti’s paper1.

Additionally, this website2 also clearly explains the technique to find the general equivalent resistance between any two nodes. The resistance between the two marked nodes in the xkcd question is,

$\frac{1}{4 \pi^2} \int_{-\pi}^{\pi} \int_{-\pi}^{\pi} \left( \frac{1-\cos(2x+y)}{2-\cos{x} - \cos{y}} \right)$ $dx dy$

which turns out to be $\frac{8-\pi}{2 \pi}$. Check out Appendix A of Cserti’s paper for a technique to evaluate the above integral.

## Pope on climate change

with one comment

An excerpt from the message that the pope released and is going to convey during New Year’s Day,

The family, the human community and the environment

Humanity today is rightly concerned about the ecological balance of tomorrow. It is important for assessments in this regard to be carried out prudently, in dialogue with experts and people of wisdom, uninhibited by ideological pressure to draw hasty conclusions

Delicious irony.

PZ Myers had linked to the webcomic Russell’s Teapot recently. From one of the comics,

Now, what’s really curious is that the fact that they do speak Norwegian in Hell!
