It's about time that we had a thread devoted to cool science news. I'm always seeing interesting articles about various science related news and I know I'm not seeing half of what's out there. Let's kick it off with this tough bug:

The mystery is solved, thank you science! Snowboarders like gravitational potential energy, all this time I thought it was the ski lift that was doing all the work. Oh contraire mon frere! :)


"A snowboarder typically gains speed by converting gravitational potential energy into kinetic energy of motion. So the more a snowboarder descends down a hill, the faster he goes".

Isn't LEGO a Danish company? I've no knowledge of patent law so please "edumacate " me as to why/how they had to file patents in the U.S.
They are a Danish company. The U.S. Patent was so that nobody in the U.S. could make the same product and sell it in the U.S. International Patent law is complicated and I don't know much about it, but it was probably safer and easier to get a U.S. Patent too instead of relying on a Danish patent applying in the U.S. based on International law.

It's very common to have the same 'invention' filed in more than one country as each country has it's own jurisdiction and IP laws.

Why do this? If you plan to manufacture, sell or use the invention in Country X to any significant degree, you'll probably want to have IP coverage there to help protect your interests. Moreover, the country selection could be defensive in nature. For instance, if a competitor has manufacturing capability in Country Y and you believe they would be inclined to copy/manufacture your invention, you would probably want a filing in Country Y as well... Of course, all these filings start getting expensive to initiate and maintain and so you have to be a bit strategic about it..

This fascinates me.

I first encountered the notion on quantum entanglement in Orson Scott Card's sci-fi novel Ender's Game. Humanity's greatest weapon was a communication device called the ansible which allowed humans to communicate in real time across light years of space.
