Visualizing Covid-19 cases in San Diego by zip code using Bokeh

I was refreshing my understanding of probability and random chance. I think that a simple experiment of tossing a coin and observing the result is very useful in understanding these concepts. As we know a coin when tossed/flipped will result either in a HEAD or TAIL. So a simple …

I have been using VIM lately for software development in Python. I gave a lightening talk on my experiences using VIM at San Diego monthly meetup. You can see my presentation slides here You can see my reveal-js source here

As I was migrating blog posts from my wordpress website to pelican based static website, I noticed an old python code written for communicating and controlling a Princeton Instruments Acton SP2150i Monochromator. As I looked at the code, I noticed methods in the class such as get_nm() and set_nm(). I …

It is common to measure the peak absorbance of the plasmonic nanoparticles in solution and then get the following: Molarity (moles/liter) Number of particles per ml Weight concentration (ug/ml) I wrote a small python function to extract these parameters. The following inputs are needed for the function d_nm …

Energy band diagrams are used to visulize the electron and hole transport in Solar cells and LED research. I want to quickly draw them and came up with a python module. Here's an example on how to use this code. from Band_diagram import metal, semiconductor, plot # Define the metals and …
