Medium has become a great source for articles of any kind. This includes also programming tutorials covering data science or machine learning topics. But covering actual coding parts requires one thing: a proper formatting and programming-language-depending colour-highlighting. Sometimes one sees code snippets in the following format:
# Import standard module
import time# Print the current Unix Time
… this format is totally fine for a few lines of code, but covering an entire tutorial in these grey-style blocks are tiring to read. Instead, most writers on Medium use GitHub GIST. GitHub provides a simple link of a created…
No, I do not want to write generic tips, motivational speeches about life and academic research or supportive ideas to prevent procrastination. It is not about finding the right supervisor or working group. You may have already started or you stumbled across this article to get new impulses for a new working framework.
In this article, I would like to share my own experiences and methods I actually used and that helped me for years! I would like to provide ideas that are not all an “own creation”. …
Radiation pressure … a quantum effect that is known and observed on microscopic scales can also cause (after some time) macroscopic outcomes.
In 1963 the National Astronomy and Ionosphere Center (NAIC) was founded and an over 300 m diameter radio telescope was build in Puerto Rico: The Arecibo Observatory. For over 50 years this instrument was the largest single-aperture radio telescope in the world. Eventually, an over 500 m diameter dish was setup in China a few ago.
This year, after countless hours of observations, dozens of scientific discoveries and resulting publications the observatory shut down its operations after a…
It’s the 30th June 1908. A huge explosion devastated in a short period of time hundreds of square-kilometres in the Russian region of Tunguska. Millions of trees were bend and burnt down in this Siberian region. For the researchers and people who live there, this so-called Tunguska Event was a mystery of unknown cause.
What happened? Well, there are several explanations:
This is the 24th part of my Python tutorial series “Space Science with Python”. All codes that are shown in the tutorial sessions are uploaded on GitHub. The shown Python library SolarY can be found on GitHub, too. Enjoy!
Last time we discussed how one can develop sustainable and (relatively) accurate and well tested code: e.g., by using a Test Driven Development (TDD) approach.
Let’s recall our project idea and purpose briefly:
This is the 23rd part of my Python tutorial series “Space Science with Python”. All codes that are shown in the tutorial sessions are uploaded on GitHub. Enjoy!
Last time we discussed the concept of Test Driven Development, short: TDD. TDD shall help us to develop a Python library for our project that ensures from the beginning on less bugs, a higher reliability (and quality) and maintainability. Of course we will develop new numerical simulations and model a complex “computational chain” to determine the detectability of Near-Earth Objects (NEOs). …
In the last couple of weeks we learned some space science and astro-dynamical basics as well as Python libraries and some space science use cases. After 20 tutorial sessions we are ready to aim for a first, larger project.
Near-Earth Objects (NEOs) are minor bodies, like asteroids, comets and meteoroids that have a perihelion of equal or less than 1.3 AU. Currently (Mid 2020) 25,000 objects are known that are separated into 5 sub-categories. Partly, these objects encounter our home planet closely or cross even its orbit. Entering Earth’s atmosphere, small NEOs with a diameter of only a few meters…
This is the 22nd part of my Python tutorial series “Space Science with Python”. All codes that are shown in the tutorial sessions are uploaded on GitHub. Enjoy!
No, we are not yet starting with any Near-Earth Object (NEO) related Python development or implementation. We need to sharpen the axe before we can cut any tree. In our case: Let’s dive into some development concepts that will lead to a sustainable long-term project and Python library.
How do you code? Most developers (either free-time coders or professionals) like to see quick results; they develop a prototype, some clickable interface, or…
This is the 21st part of my Python tutorial series “Space Science with Python”. All codes that are shown here are uploaded on GitHub. Enjoy!
In our last 20 Space Science with Python tutorials we have learned some astro-dynamical basics, miscellaneous Python libraries and tools that are helpful for a space scientist and we worked on a few use cases (like the comet 67P, the movement of Venus in the sky any many more).
We have a solid skillset to start working on a first science project. …
Do you know where we are currently? Not you, personally, but our home planet? Well, somewhere in the Solar System, between Mars and Venus.
Sending spacecraft missions or probes into space requires more, detailed knowledge of our position in space. We need a coordinate system (see my last article) and mathematical methods to compute and predict the position in three dimensions, as well as the corresponding velocity vector of our planet (in which direction is our home planet heading?).
Do not worry though. You do not need programming skills and you do not need to be a “rocket scientist” to…
