Online education, then, can serve two goals. For students lucky enough to have access to great teachers, blended learning can mean even better outcomes at the same or lower cost. And for the millions here and abroad who lack access to good, in-person education, online learning can open doors that would otherwise remain closed.

The Central American isthmus is a region of great contrasts, but also of heartening unison. Millions of men and women share dreams of freedom and progress.

When I walk up on that shore in Florida, I want millions of those AARP sisters and brothers to look at me and say, 'I'm going to go write that novel I thought it was too late to do. I'm going to go work in Africa on that farm that those people need help at. I'm going to adopt a child. It's not too late, I can still live my dreams.'

The meteoric rise of the 'wellness' industry online has launched an entire industry of fitness celebrities on social media. Millions of followers embrace their regimens for diet and exercise, but increasingly, the drive for 'wellness' and 'clean eating' has become stealthy cover for more dieting and deprivation.

A high nutrient diet, if widely adopted, could bring millions of people in touch with true hunger, and stop the proliferation of obesity and preventable chronic disease.

The human diet, for millions of years, did not contain any added salt - only the sodium present in natural foods, adding up to only about 1000 mg sodium per day.

Just like zillions of children, album covers educated and informed me, and certainly did I later transpose organically, rather than by intent, those principles both in fashion design and photography.

You have to have talent to design and to dress thousands of women or millions of women around the world. And you know very well, the only thing they want is to look more beautiful.

I'll never forget Hurricane Katrina - the mix of a natural and a man-made catastrophe that resulted in the death of over 1,500 of our neighbors. Millions of folks were marked by the tragedy.

Millions long for immortality who don't know what to do with themselves on a rainy Sunday afternoon.

There are hundreds of millions of people on dating apps every day, but apparently, no such apps cater solely to sports fans.

Smallpox, which spreads by respiration and kills roughly one in three of those infected, took hundreds of millions of lives during a recorded history dating to Pharaonic Egypt. The last case was in 1978, and the disease was declared eradicated on May 8, 1980.

For millions, Roger Ebert will be remembered as a writer and television personality who brought a sense of passion and excellence to his craft. For me, he is a man who fused joy and courage as few others ever have. My life was enriched by having such a friend; it is poorer for losing such a friend.

Remember in 1973 the same science chatter said that the coming Ice Age is going to occur, we're going to lose millions of people. And the politicians knew how to solve it, they just didn't have the courage to solve it; they were going to put coal dust on the Arctic.

Just two weeks ago, millions of Iraqis defied the threats of terrorists and went to the polls to determine their own future. I congratulate the Iraqi people for the courage they've shown in making these elections so successful.

There are two types of courage involved with what I did. When it comes to picking up a rifle, millions of people are capable of doing that, as we see in Iraq or Vietnam. But when it comes to risking their careers, or risking being invited to lunch by the establishment, it turns out that's remarkably rare.

I know that millions of Americans from all walks of life agree with me that leadership does not mean putting the ear to the ground to follow public opinion, but to have the vision of what is necessary and the courage to make it possible.

To have so many years in the rap industry and so many number one songs, and sold so many millions of records, introduced the world to people like Cool & Dre, DJ Khaled, Pitbull, Rick Ross, Trick Daddy, Remy Ma, Big Pun, Rico Love... I could go on and on. Having been able to influence the rap game for so long is very important to me.

It's really cool when the thing you are working on as a small team gets embraced by millions, but in the end, it's about your character and the script and your director and the rest of the cast and crew.

I call the blockchain 'the Internet of value' and 'the Internet of trust.' Because everything becomes trustless. It's a big distributed ledger. Think of it like an Excel file that's being maintained and updated and managed by millions of computers around the world.

As the world transitions to the Internet of Everything - where people, processes, and data are intelligently connected - we'll be linked in even more ways. Here, billions and trillions of sensors around the earth and in its atmosphere will send information back to machines, computers, and people for further evaluation and decision-making.

Millions of nerdy kids who grew up in the 1980s could only find the components they needed at local Radio Shacks, and the stores were like a lifeline to a better world where everybody understood computers.

Why is it that I notice so many brilliant scientists using Macs for their personal computers; why does the Lawrence Livermore & Berkeley Labs buy millions of dollars worth of Macs?
