I didn't know anything about it but since reading your question, I have googled it and learned something new. Thanks
It was something I did not realize until doing some research on Google. As a result of your question.
Not until now. It's sad that I knew what the Matrix was, but not the troposphere. Sadly, I am a product of the American education system:)
Yes - I was made aware several years ago in High School.
Not until reading this question. Thank you.
