Motion sickness is also known as travel sickness, sea sickness or air sickness. It can happen in a number of situations, not all of which involve movement, and is a very unpleasant sensation. As part of our Have You Ever Wondered series, our Science Editor Sam finds out what causes motion sickness, and if there is anything you can do to prevent it.
Facebook: What’s it all about?
Facebook is a website created in 2004 by a US college student Mark Zuckerberg. It started off as a way of college students to network with each other, which quickly spread throughout the world, and now has millions of members. Facebook works by people registering and creating a profile for themselves, and then becoming ‘friends’ with other people. A user can update their status to let their friends know what they’re up to, upload photos to share, send private messages to each other, and play games. You need to be at least 13 years old to be a member, and Facebook is banned in some countries altogether, like Syria and Iran.
The thing that I like about Facebook is that it is a quick and easy way to keep in touch with all those people I have met in real-life but don’t have time to write to or call them, like old workmates or family that have moved away. I can upload a photo and anyone I am friends with can see it, and comment on it. In the days before Facebook, if I wanted to share a photo with everyone, I would have to print out lots of copies and send them in the post, which is very expensive and time-consuming. Since I joined Facebook, I am better at communicating with people and I enjoy seeing what all my friends and family are doing. I think that I know them better and it’s easy to keep-in-touch.
