Candles were expensive.

The moment the wind blew in, the candle went out.

And the windows which prevented us from having candle light were gone too.

Now many people begin trying to thumbtack the candle to the wall.

But it can also have this other function, as a platform for the candle. The candle problem.

But for the real candle problem, you don't want to be looking like this.

And I say to you, Your job is to attach the candle to the wall so the wax doesn't drip onto the table. Now what would you do?

Somebody, some people and I saw somebody kind of make the motion over here some people have a great idea where they light the match, melt the side of the candle, try to adhere it to the wall.

Nour Abed, a school teacher, tweets My students at school when I find tracks of melted wax on their notebooks, I realize that they wrote their homework by candlelight!

Now I want to tell you about an experiment using the candle problem, done by a scientist named Sam Glucksberg, who is now at Princeton University in the U.S.

Now the United States has a particularly important role to play in this to keep our education system globalized, to keep our education system open to students from all over the world, because our education system is the candle that other students come to light their own candles.
