### Is it just me ??

I want to clarify something, especially to the women out there, when you see a guy, your brother, cousin, uncle, father, husband whomever looking very serious, looking as if he's trying to calculate 658 * 917 in his mind, don't start thinking that he's a genius, he's in a very tough spot in life, he is trying to solve some serious problem. whatever it is ... really saying as far as from what i know, when we look like that, we have songs playing in the background of our mind, movie bits whizzing past us, comedy scenes, and sometimes stuff which cannot be blogged about etc etc and not mostly some serious shit. there is a very less probability that we're thinking of something very serious, cos if we are working on something very seriously, we wont be sitting around on the table for dinner, munching on chips and sipping coke on the couch but some place different, maybe in some place more suited, like maybe an office, ohh i don't know, am not sure. there are times when every man goes through this very tough phase, too much work, stress, peer pressure that he brings all this shit home with him, but that never lasts for more than a month(unless you're someone who doesn't belong where he's working). so, everytime you see us making that face, you may call it serious, we call it leisure don't ask us what we're thinking about, cos you wont stop asking us until we give you an answer and the answer would basically be something we made up on the spot, and all this would get very ugly if you get to know what were really thinking about.

### Animation using GNUPlot

Animation using GNUPlotI've been trying to create an animation depicting a quasar spectrum moving across the 5 SDSS pass bands with respect to redshift. It is important to visualise what emission lines are moving in and out of bands to be able to understand the color-redshift plots and the changes in it.
I've tried doing this using the animate function in matplotlib, python but i wasn't able to make it work - meaning i worked on it for a couple of days and then i gave up, not having found solutions for my problems on the internet.
And then i came across this site, where the gunn-peterson trough and the lyman alpha forest have been depicted - in a beautiful manner. And this got me interested in using js and d3 to do the animations and make it dynamic - using sliders etc.
In the meanwhile, i thought i'd look up and see if there was a way to create animations in gnuplot and whoopdedoo, what do i find but nirvana!

In the image, you see 5 static curves and one dynam…

### on MOOCs.

For those of you who don't know, MOOC stands for Massively Open Online Course.

The internet is an awesome thing. It's making education free for all. Well, mostly free. But it's surprising at the width and depth of courses being offered online. And it looks like they are also having an impact on students, especially those from universities that are not top ranked. Students in all parts of the world can now get a first class education experience, thanks to courses offered by Stanford, MIT, Caltech, etc.

I'm talking about MOOCs because one of my new year resolutions is to take online courses, atleast 2 per semester (6 months). And I've chosen the following two courses on edX - Analyzing Big Data with Microsoft R Server and Data Science Essentials for now. I looked at courses on Coursera but I couldn't find any which was worthy and free. There are a lot more MOOC providers out there but let's start here. And I feel like the two courses are relevant to where I …
