Hi,
This article seems to be translated from this original post in French. Citing his/her sources is very important, especially when writing about science. Moreover, Google-translating posts in other languages is something not encouraged on steemit. It would be better to write something on your own, possibly giving the link to the original article you liked and explaining why you liked it. This is known to attract better rewards. Thanks in advance for your consideration.
Thank you for your reply, yeah you're right but write with your own language is so hard especially with these topics.
