ASTRONOMY IS FUN

In the last decade, the black hole became a hot topic to be discussed. After astronomers worldwide announced their first-ever picture of a black hole in 2019, The Royal Swedish Academy of Sciences awarded astronomers for their discovery about the black hole a year later. Roger Penrose builds the theory, while Reinhard Genzel and Andrea Ghez work in the observational.

People can understand a black hole in a simple by watching a science fiction film, Interstellar. Christopher Nolan produces it. He collaborates with a senior cosmologist, Kip Thorne as a scientific consultant. …

Getting Started

Data visualization is used to shows the data in a more straightforward representation and more comfortable to be understood. It can be formed in histograms, scatter plots, line plots, pie chart, etc. Many people are still using Matplotlib as their back-end module to visualize their plots. In this story, I will give you some tricks, 5 powerful tricks in using Matplotlib to create an excellent plot.

  1. Using LaTeX font

In default, we can use some nice fonts that are provided by Matplotlib. But, some symbols are not good enough to be created by Matplotlib. …

Hands-on Tutorials, Introduction to Matplotlib

This story is the next part of Python Data Visualization with Matplotlib — Part 1. In part 1, we have learned how to generate and customize the scatter plot, line plot, histogram, and bar chart. This story will continue the study in Python plotting with Matplotlib concerning generating and customizing box plot, violin plot, pie chart, polar chart, geographic projection, 3D plot, and contour plot.

As in the part 1, I tell you that I have customized the default parameters in Matplotlib. Here is my plotting style

import numpy as np
import matplotlib.pyplot as plt
plt.rcParams['text.usetex'] = True
plt.rcParams['font.size'] = 15
plt.rcParams['font.family']…

Introduction to Matplotlib

Data visualization aims to present the data into a more straightforward representation, such as scatter plot, density plot, bar chart, etc. It is also useful to give readers or analysts a global picture of their data. By visualizing your data, you can detect potential outliers. In Python, you can use various modules or libraries to visualize data. One of the mainstream modules is Matplotlib. You can visualize data using Matplotlib in various plotting styles. But, Matplotlib can not show you a dynamics plot. …

Nowadays, almost all people worldwide know Bitcoin, the biggest cryptocurrency from its’ market capitalization. The invention spirit of cryptocurrency is avoiding the “Greedy of Bank”, especially after many people were suffered in The Financial Crisis of 2008. People started to create a new payment system.

Satoshi Nakamoto (an unknown person or group) invented Bitcoin in 2008. The next year, Bitcoin started to operate and released as open-source software. Bitcoin is a decentralized digital currency, where any transactions proceed without a central bank that can be transferred between users called a peer-to-peer network. The network nodes’ verification is done through cryptography…

A response to WhatsApp new privacy policy

Nowadays, people around the world are surprised by one of the largest messaging app, WhatsApp. WhatsApp updated its terms privacy policy that asking users to share their data with Facebook. It is a big contrast with what WhatsApp promised in 2014 when acquiesced by Facebook.

Even though WhatsApp had clarified some rumors, but the privacy policy seems to contradict it. I only examine one of the claims, “WhatsApp cannot see our shared location, neither can Facebook.”

WhatsApp clarification

WhatsApp will automatically collect and use precise location information of our device with our permission…


Python Visualization

A picture is worth a thousand words means that graphics can more effectively convey ideas than many words. How about animation or video? Animation or video is composed of many pictures. Of course, animation can be more effective in delivering ideas. The next level is the simulation. The difference between animation and simulation is that regardless of whether we play and replay an animation, we will get the same results (like watching a film), but it differs from a simulation. Simulation can produce a different result when we change the parameter. …

Python is one of the most popular and progressing programming languages. Based on TIOBE, a software quality company stated that Python is an aggressive programming language. In 2020, Python is on top 2, replacing Java. But, number one is still C. It was an impressive achievement for Python in the last 20 years.

Why is Python unstoppable? First, Python is working well for machine learning and deep learning. We can realize it from Google developing simple machine learning or deep learning for people via Google Colaboratory (hereafter: Google Colab). People can run their machine learning or deep learning code in…
