Beautiful Equations – BBC

“Beautiful Equations” is an extraordinary documentary about some of the most known equations and how did they changed the world. This documentary produced by BBC takes us in a journey through this wonderful world of mathematics.

You may think that math isn’t for you, however the main role is played by an artist and writer (Matt Collings)… This means that every equation is explained in order for he understand therefore we can also understand. I had a lot of fun watching this documentary and learnt a lot from a wide range of subjects. I just had to share this after posting a mathematical post :p Have a nice day! 😀

Is it Better to Walk or Run in the Rain?

Today as I walked home it started to rain. I instantly remember I had to share this video someday. It concerns a question that you maybe have asked yourself (Is it better to walk or run in the rain?). It is old but gold. I hope you like it and you may want to subscribe this mesmerizing channel. It shares “cool physics and other sweet science”. Have a nice day 😀

Nobel Prize in Chemistry – Achieving “nanoscopy”

Eric Betzig, Stefan W. Hell and William E. Moerner won the nobel prize for their inside to the nanodimensions. In this short video you will learn how they manage to accomplish a microscope that gives the opportunity to see nano resolution, passing through the theoretical limitation of 0.2 micrometres (500 times smaller than the width of a human hair). Now, scientists have the opportunity to see how molecules create synapses between nerve cells in the brain or track proteins involved in Parkinson’s, Alzheimer’s and Huntington’s diseases. [1]

I hope you liked it and don’t forget to check the link below (in “References and further reading.”), it has amazing curiosities and important information! 😀

A Glimpse of the sun’s power II: How the rainbows are formed?

You found out how the auroras are formed. Now you will learn about rainbows.

Rainbows are not formed in the practical meaning of existence, i.e. they are not real. They belong to what we usually call optical illusions. Rainbows are caused by the reflection and refraction of light in water droplets. After this the light scatters into different colors because different colours have different wavelengths. This means that they will leave the water droplet at different angles hence making a “colour palette” (ROG. BIV). [1]

What is even more interesting is that the rainbows are full circles… Want to know more? Watch this two videos of SciShow!


As always I hope you learnt something new! 🙂 [2]


Minutephysics has just made a wonderful video explaining the origins of the acronym ROG. BIV. Watch it!

I’m going to categorize this under the week themes despite the fact that it doesn’t fulfill the requirements for it (i.e. it wasn’t posted during that time).

A Glimpse of the sun’s power: How the auroras are formed?

CME Week NASA Sept 22-26
With NASA having this week CME as theme I sieze this opportunity to invite my followers and visitants to read this article about CMEs and auroras 😀

Gleams of Knowledge

I never asked myself this question but as I was searching about the sun, I found how auroras are created. First let me introduce you the Coronal Mass Ejection (CME). A CME is an explosion that occurs in the sun for several hours it happens when two different magnetic fields are brought together this results in the release of high energy particles (solar energetic particles).[1] [2] This massive explosions due to the high energy particles can affect the Earth’s magnetosphere by their enormous energy that turns into a geomagnetic storm thus affecting our electronic devices (e.g. making Gps inaccurate) [3] [4] See the article on for more information concerned to the video [5]

CME are the reason for the formation of the auroras along with the solar wind (plasma released on the upper atmosphere of the sun, consisting mostly in electrons and protons) [6]. When it approaches Earth, it triggers reactions…

Why can’t you put metal in the Microwave?

Have you ever wondered about this?

Since I was told that I couldn’t put metal in the Microwave it has been an unanswered question in my mind. But today I found this interesting video that explains it… As always hope you like it and take something from it…

TED moments!

We love TED, it shares new ideas based on the activity of renown scientists, economists, artists, etc… It makes knowledge more accessible so we are proud to everyday share with you a TED video. Hope you enjoy it!


We talked about nuclear fusion, now it’s time to hear how important is to have new available options for energy. Especial if they are clean energy with low-level radioactive waste. In this talk, Dr. Steven Cowley takes us in a quick lecture to the ambient challenges of humanity.
