“The Sun” – Reflexion on what we learnt

“The Sun” – Our first week theme

"Handle on the Sun" 1999 - NASA/European Space Agency
“Handle on the Sun” 1999 – NASA/European Space Agency

It took awhile to do it but it has finally ended, a lot of research and passion for knowledge were the key ingredients for this magnificent result.

We learn so much and share what we learnt. Now you know about the sun and what is interesting about him.

  1. How the Sun sees you! – Our first post devoted to elucidating what is the electromagnetic spectrum and the electromagnetic waves released by the sun. After this brief explanation we saw how infrared sees us.
  2. How can you measure Earth’s circumference with the sun? Eratosthenes answers… – Eratosthenes an amazing polymath measured the earth’s circumference, and we reveal the way he made it. Ancient Greeks had always their heart in discovering the Universe.
  3. Sun exposure can make you live longer! – Have you ever heard about the sun’s benefits? Here we depict the most interesting finds about the curative values of the sun. Multiple Sclerosis and the reduction of hypertension and cardiovascular disease. If you haven’t seen it’s a must so be sure to click in the link!
  4. A Glimpse of the sun’s power: How the auroras are formed? – Ever wondered about how auroras are formed? Here you will find the answer, it is sure a glimpse of the sun power!
  5. Set the controls for the heart of the Sun – The title says it all, prepare and embrace what’s in the Sun’s core. New ideas that can change the world.
  6. (Exceptional) A Glimpse of the sun’s power II: How the rainbows are formed? – This is a continuation regarding some strange breathtaking effects that the sun offers us to marvel.

 


Also there was a post with two documentaries, while it is not an article it is definitively something that you have to view if you want to close this theme! (Documentaries “The Sun”)


 

The Sun’s structure


Thank you for voyaging through the Sun with me. Stay close for more travels arround different themes!

Set the controls for the heart of the Sun

This is my last article on the Sun theme. I learned a lot doing the researches and I’m happy with the final result, 6 posts (including this one) with interesting new “stuff” to share! I would like some feedback so comments are more than welcomed!

Set the controls for the heart of the Sun

As I was researching this week theme I revisited one TED talk that made me gain confidence and It’s one of the reasons why I’m here today sharing what I everyday learn. This TED talk was made by Taylor Wilson (the second most young person to develop a nuclear fusion reactor).

Nuclear fusion is the process in which two or more atomic nuclei collide at a very high-speed, they merge together and form a heavier nucleus (with more energy) this happens because when they join into one single entity they lose mass that turns in energy. [1] [2]

In the core of the Sun, nuclear fusions take place hence releasing energy in enormous proportions making photons that once on the outside of the sun are mostly in the range of infrared/visible light/ultraviolet. [3]

I continued looking for this amazing teenagers for making this post and one news stroke me, a british boy had surpass this deed. Jamie Edwards became the youngest teenager to build a nuclear fusion reactor with 13 yo he beaten the achievement of 14 yo Taylor. [4]

At the end of that report there’s an announcement of an exhibit at the Imperial College London labeled “Set the controls for the heart of the Sun”, what clearly refers to the nuclear fusion happening at the Sun’s core. [5]

A little more about nuclear fusion… Nuclear fusion is still in research time, but it might one day get to another degree, the degree of supplying abundant and clean energy for all the planet. What is good for this source of energy is that it is much safer than the nuclear power plant energy created (nuclear fission) because it produces no high-level radioactive waste so It will not have the risk of disaster like the one in Chernobyl. [6]

A step to the future: A US$50 bilion project (building costs in July 2014) initiated in 2007 by 6 entities together (China, United States, Japan, European Union, India and South Korea) called ITER aims to create the first fusion power plant. [7]

Good News: Nowadays an experiment made in US changed the idea held that it took more energy for igniting fuel than the energy produced. (February 2014) [8]

Pink Floyd and the Sun

Pink Floyd, for those who never heard of them, are an English rock band formed in London in 1965. Well I could talk more about them but I guess that music, more than words, expresses their path and singularity. [9] “Set the controls for the heart of the Sun” is a track from their second album A Saucerful of Secrets released in 1968 it deploys a psychedelic rock music, paced and full of spiritual force.

I strongly recommend you to listen this track…

In this manner I say “au revoir” and get ready for the next week theme…
