podcast

The technical details of the podcast I found are:

1. An audio podcast on nature.
2. Conducted in English.
3. Title: A pair of unusual meteorites
4. Episode: Gravity's role in star formation
5. Date: January 8, 2009
6. Time: 27:13
7. Website: http://www.nature.com/nature/podcast/archive.html

The theme is gravity's role in star formation, unusual meteorites, what happens when you 'over-squeeze' photons, and predictions for science in 2009.

Since i was really young I have always been intrigued by nature and astronomy. So it is not a surprise that surfing on the internet for an interesting podcast I first hit the nature sites and a subject on meteorites and star formation.

It describes the star formation process and how gravity helps dust and air mix together to form bodies that later become eventually stars that we so often watch and admire. It is a never ending process that without gravity would not be possible.

Gravity is acting as a sticky effect to help particles mix and interact to form clouds of dust and then mass bodies that get larger and larger over years and centuries.

It is amazing how gravity, a power that we know it exists and is all around us, almost never sensed has such a significant role in the formation and survival of our world.

Even if you are not too much interested in nature matters I promise you this episode will attract your attention and help you understand better how the world around us was formed and how it is all happening through gravity and balancing.

Agree/Disagree

1) I disagree because some kids have health problems but some others don't. Apart from the health problems kids who are healthy have problems too. Health is an important problem that’s why i disagree. Moreover there are kids with mental problems. They face different situations from other kids behaviour .e.g.(bullying)


2) Because a kid without house and family can never be happy. Despite that if the family of those children has high networth the kids could be happy. They won’t have economic problems too. Instead of that nothing else can make you feel depressed. For example if a child does not get something that he/she wants with all of his heart, e.g. (new computer) he/she says that he feels sad and cheerless. However the kid is depressed for just a small period of time until he forgets it. Peoples wants are infinite and we can’t have everything we want.
