SHO, DHO and a week filled with popular talks

Since I learnt how to use ipywidgets to make small visualizations, I've wanted to make a model of simple and damped harmonic oscillators, using euler's or runge-kutta methods to solve the second order differential equation. And I finally make them, here and here.

Otherwise, it's been a week filled with popular science talks. I attended a talk on tuesday on the landau theory describing fermi liquids. On wednesday, there was a talk on light that twists inside optical fibers, followed by a talk on particle physics and the Belle detector in Japan. The first talk was about modes of polarization and the methods to be able to generate vortex beams in fibers. He then talked about how vortex modes can be used advance communication technologies. In the following talk on high energy physics, the speaker talked about how the BELLE detector upgrade will help in understanding the CP violation, to study dark matter and how the new instrument is a huge upgrade on it's predecessor.

And today, there were two talks, one on Seismology of Sun and Stars and the second by Viswanathan Anand. The first talk was on the study of the sun's interior and the use of acoustic waves to do so, how studying the intensity of the surface of the sun at various scales helps in understanding convection, which in turn helps understand the underlying magnetic structure of the sun. He talked about how Kepler has contributed to astroseismology and how the upcoming missions, PLATO and Gaia are expected to take the field to new heights. And finally, Viswanathan Anand talked about how he got introduced to Chess, his experiences from his early professional life, his games and in general, playing Chess for a living. Filled with interesting anecdotes from his past, it was a talk that showed how practice and perseverance are what really matter in life, just being smart isn't of much use.

I shall get back to practicing problems on general relativity...

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 …

On programmers.

I just watched this brilliant keynote today. It's a commentary on Programmers and the software development industry/ecosystem as a whole.



I am not going to give you a tl;dr version of the talk because it is a talk that I believe everyone should watch, that everyone should learn from. Instead, I am going to give my own parallel-ish views on programmers and programming.
As pointed out in the talk, there are mythical creatures in the software development industry who are revered as gods. Guido Van Rossum, the creator of Python, was given the title Benevolent Dictator For Life (BDFL). People flock around the creators of popular languages or libraries. They are god-like to most programmers and are treated like gods. By which, I mean to say, we assume they don't have flaws. That they are infallible. That they are perfect.
And alongside this belief in the infallibility of these Gods, we believe that they were born programmers. That programming is something that people are born wit…
