CNN Profiles: The teacher in the one world schoolhouse

(CNN) – This is the time in the school year when parents really have a sense of whether their children are struggling academically.

For those parents whose children are having a hard time with math, and are seeking help, one name seems to be popping up more and more: Salman Khan.

Each month, 7 million children and adults log on to Sal Khan’s website, the Khan Academy, to get clear, entertaining, informal video tutorials on everything from basic addition to advanced calculus and more.

So who is Sal Khan? Where does he get his credibility?

Is it from the three degrees he earned from MIT or the Masters he received from Harvard after being raised by a single mother who struggled to make ends meet?

Is it from the raves he gets from Bill Gates who uses Khan’s online videos for his own children?

Read the full story and hear the podcast from CNN Radio.

Searching for news that matters

By Michael Schulder, CNN

(CNN) To mark one of the biggest science news stories of the year, I've retooled an old story to make up the very first physics joke in history. Here it goes.:

A physicist is bending down, at night, searching for something beneath a lamp post.A guy walks up to him and says "what are you looking for?
Physicist: A Higgs particle.
Guy: Where did you see this Higgs particle last?
Physicist: I've never seen one. Nobody has.
Guy: Then why are you looking under the lamp post?
Physicist: That's where the light is.

Aah, if it were only that easy.

In fact, if it were possible to find a Higgs particle under a lamp post you would see every ambitious physicist in the world wearing knee pads, crawling from lamp post to lamp post, coast to coast.

That's because a Higgs particle. also known as the God particle, is believed to be the final link in a mathematical formula that explains what makes matter matter.

That's tough to explain in plain English, so I've enlisted one of the world's most respected and plain-spoken physicists.
