Fabry Perot Etalon transmission curves

After a long time, I got back to making small interactive plots/visualizations using ipywidgets on ipython. For the time being, nbviewer doesn't seem to be working but you can access the .ipynb file here and the relevant .html file here. Simply put, the Fabry Perot etalon is two mirrors aligned parallel to each other. Their transmission properties depend on the reflectivity of the mirrors and on the phase of the incoming wave. It seemed like an easy enough one to make but I never worked on it, made it in about 15 mins in the evening when I wasn't able to get much else done. Otherwise, I'm catching up on gnuplot tricks and function definitions in fortran.

Animation using GNUPlot

Image
Animation using GNUPlot I'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 curv

Arxiv author affiliations using Python

So, I wanted to get author affiliation information from papers on arXiv. arXiv provides with an API to bulk query their database and get information. Following that, I look for the attribute 'arxiv:affiliation' in the html data. Here's the code - import urllib from BeautifulSoup import BeautifulStoneSoup   url = 'http://export.arxiv.org/api/query?search_query=all:astro&start=0&max_results=1000'   data = urllib.urlopen(url).read() soup = BeautifulStoneSoup(data) #print(soup.prettify()) #list = soup.findAll('arxiv:affiliation') #for i in range(len(list)): #        print list[i].contents   test = [tag.string for tag in soup.findAll('arxiv:aiffiliation')] Now, the problem I'm having is that I'm getting affiliation of all authors which I want to split into sets of affiliations of authors of a paper, which I'm stuck on at the moment. Once I get that part, I can move on to the next part of this pet project, displaying these

Thoughts on the National Deep Tech Startup Policy

The Principal Scientific Advisor to the Government of India published a draft policy to support and nurtue the unique requirements of Deep Tech startups in India. I just finished reading it and put together a few comments in a FOSS United forum thread . I will probably read it again a week or so later and try to update my comments on the thread with any new insights/thoughts I have.
