Steve Jobs wanted the iPad to herald a revolution in textbooks.
In his biography of the late Apple co-founder, author Walter Isaacson said Jobs saw textbooks as another market ripe for disruption by releasing digital versions on the iPad.
Digital textbooks usually include dynamic elements, like pictures or video clips. Chaim Gingold has taken that to the next level with "Earth Primer", an app that teaches you about our planet by letting you play with an interactive model of it.
"Earth Primer" allows you to summon rainclouds to send streams of water cutting through mountains to demonstrate how erosion works instead of just telling you. You can also raise the sea level, create glaciers, even move continental plates around - all to explain the inner workings of the Earth.
Watch Gingold tell Kristie why he created the app in the clip above.
Rick Carrier was barely out of his teen years when he helped save tens of thousands of lives. If there is anyone fit to be called a hero, it's him – and a very unassuming one at that.
Carrier was the first American to stumble across the Nazi-run Buchenwald concentration camp in Germany on April 10, 1945. It was his twentieth birthday. The next day he returned with reinforcements, and helped liberate Buchenwald.
At 90 years old, the World War II veteran's recollection of the sights, smells and emotions at the very moment he helped liberate the camp are just incredible.
Listen as he shares his story with Kristie Lu Stout.

The situation in Ferguson, Missouri is a reminder of the deep racial division in America.
Protesters in Ferguson and across the United States feel that Michael Brown was singled out by police because of his race.
CNN contributor L.Z. Granderson says there is a lack of trust between minorities and police, as well as a lack of empathy between blacks and whites in the country.
It's a problem he's experienced way too often.
"I've lost count the number of times I've been pulled over by a police officer," he tells me from Ferguson. "The first time that an officer pulled a gun out on me, I was 12 years old. He told me I looked like someone."
"We're talking about a 30 year gap in my life in which I continue to look like someone that police are interested in," Granderson says. "I have never committed a crime. I have never been prosecuted. But I keep feeling I am being persecuted."
Here's Granderson on the racial divide in America and the anger surrounding the Ferguson grand jury decision.
Take a listen. It's worth your time.
As Hong Kong's Umbrella Movement stretches into week nine, more barricades are coming down in the district of Mong Kok. So should pro-democracy protesters withdraw or wait it out?
One high-profile supporter is urging student leaders to stand down.
"It's about time we retreat," says Jimmy Lai, a fervent China critic and media mogul. He has been working from his protest camp in Admiralty since the start of the action.
Lai calls the Umbrella Movement a "war" that will extend far beyond the battle of the last two months.
He fears that growing public resentment to the protests, which has caused major traffic disruption throughout the city, will damage the pro-democracy movement.
According to a poll released by the University of Hong Kong last week, 8 out of 10 people surveyed think the demonstrators should leave the streets and go home.
"If we will lose the moral high ground, it will be very difficult for us to come back later," Lai tells me.
Click on to hear Lai's call for the protesters to retreat, regroup and return at a later time.
A jolt of energy has just hit the International Space Station.
In days that can feel like endless nights, what’s more welcoming than a burst of caffeine?
But with Italy’s first female astronaut now on board, regular old space coffee just won’t do.
Samantha Cristoforetti brought with her the very first zero-gravity espresso machine.
Call it the elephant in the room. It may be a cliché, but the fact that elephant populations are dwindling around the world is a growing problem that can’t be ignored.
Africa has seen its elephant population decline from 1.3 million several decades ago to an estimated 419,000 now. Poaching still goes unchecked in some parts of the continent.
Tanzania lost 10,000 elephants to poaching last year alone – more than any other country in Africa.
And the EIA makes damning allegations about China, the world's largest ivory market. It links some smuggling to Chinese officials who have accompanied the president to Africa. Beijing has denied the claims.
But it’s not just African elephants facing a perilous future. Their Asian cousins are also in a battle for survival. FULL POST
An American nurse has become the first person to contract Ebola in the U.S., raising fear and alarm about the outbreak in the West.
In the Ebola hotzone of West Africa, desperation grows as thousands of people are struck by the deadly virus - including healthcare workers on the front line.
The outbreak may be spreading, but professor and senior United Nations advisor Jeffrey Sachs tells me Ebola can be controlled in 6 months.
"This is a controllable epidemic but the epidemic has so far outrun the control efforts," he says.
"This is logistics, it's equipment, it's basic health protocols, it's diagnostics. All the pieces of a basic control system that need to be rapidly scaled up."
Watch the video to hear his recommended next steps, and what is at stake for Africa and the world if Ebola is not contained.
