The amazing, engaging, math exponent.
Think of a big number. How about one million? It's a thousand thousand. That's a lot. If you counted nonstop to a million, it would take you about 23 days.
A million is small compared to a billion, which is a thousand million. Want to count that high? You'll be at it for 95 years. But a trillion makes a billion look puny. A trillion is a thousand billion (or a million million). Counting that high would take you 200,000 years. Have fun!
Of course trillion is not the biggest number. There's quadrillion, quintillion, sextillion, septillion, octillion, nonillion, decillion and more. Each is a thousand of the previous one. There's even a humongous number called vigintillion, a one with 63 zeros.
But vigintillion is a shrimp compared to a googol. Googol? Notice how it's spelled: G-O-O-G-O-L, not G-O-O-G-L-E. The number googol is a one with a hundred zeros. It got its name from a nine-year old boy. A googol is more than all the hairs in the world. It's more than all the grass blades and all the grains of sand. It's even more than the number of atoms in the universe. Astrophysicists estimate the number of atoms to be a one with 82 zeros. You'd need to add 18 more zeros to get to a googol.
Incidentally, a few years ago, the two men who had invented a powerful new internet search engine decided to name their website and company for the gigantic number googol. But they spelled it wrong. That's why the company Google is spelled with an L-E. But the number googol is still spelled with an O-L.
Googol is so large that it's practically useless, but the boy who named it came up with a name for an even bigger number, "googolplex." A googolplex is a one with a googol zeros. There isn't enough ink in all the pens of the world to write that many zeros but feel free to give it a try.
So is googolplex is the biggest number? What about a googolplex and one? Two googolplex? A googolplex googolplex? Any number you say, I can say one bigger.
I hear you asking, "What about infinity? Isn't that the biggest number?" Sorry, but infinity isn't a number. A number specifies an amount and infinity is no amount. It means "goes on and on forever."
And that's what numbers do. They go on and on forever. Infinity is not a number but numbers are infinite.

The amazing, engaging, math exponent
Do you want to be a lot older? Here’s how: state your age in seconds instead of years!
Ready to do some math? But what math will you do?
First you have to design a problem-solving strategy. There are many approaches but for all of them, consider that with every passing second, you are a second older. So your age is a moving target. Best to pick a specific time of day and find your age in seconds at that time today.
It doesn’t really matter what time of day you pick. If you can find out from your birth certificate what time of day you were born, you could select that time today for your target. If you were born at 4:14pm, you will find out how old you are (in seconds) at 4:14pm today.
Or just pick any time today and pretend you were born at that time.
What next? I hope you will try out your own approach but here is a simple strategy that would work:
Step 1. How many days old are you? Figure out how many days elapsed between the day you were born and your most recent birthday. There are 365 days in a year, not counting leap years. In your lifetime, every year divisible by 4 was a leap year and it had a 366th day, which was February 29th. So add an extra day for each February 29th you’ve lived through.
Then figure out how many days have passed since your last birthday. Try to find a way to make this job quicker than counting each day. Look at calendars as you do this to find shortcuts.
Now you have your age in days. It’s already looking like a big number, isn’t it? Just wait!
Step 2. How many seconds are in a day? Think about how to figure this out. You know how many seconds are in a minute (60) and how many minutes are in an hour (60) and how many hours are in a day (24). So how many seconds are in a day? Multiply 60 X 60 X 24. Bet you didn’t realize a day was so long!
Step 3 So what’s Step 3? You now know how many days you have lived and how many seconds are in a day, so what do you do next? Again, multiply!
Next time someone tells you you’re not old enough to do something, you can tell him or her, “Oh yes I am. I’m 299,592,620. That’s what I was at 11:30 this morning. Now I’m even older!”
Good luck with that!

When you think of the Olympics you think of the sports: Speed skating, Bobsled. Snowboarding. Track, Gymnastics. Swimming. Tennis. Just to name a few.
You may even think about some of the Olympians: Snowboarders Shaun White and Kelly Clark. Speed skater Apollo Ohno. Swimmers Michael Phelps and Katie Ledecky. Or even gymnast Simone Biles and sprinter Usain Bolt.
But do you ever think about the science behind each sport? You should. Math and physics play a huge part in every part in the Olympics. Think about it. One of the most basic forces, friction, is a factor in everything an athlete does. What is friction? It’s the force that pushes back on you as you swim through the water or run through the air. Friction not only affects an athlete, but also the object they may be throwing, hitting, or kicking—like a baseball, a tennis ball, or a soccer ball.
Movement of any kind deals with physics of air flow, engineering design, and (unfortunately) sometimes collision. The verdict? Athletes need to know a LOT of science to do well in their sports.
Science is not just found in the activities themselves but also in the equipment they use and clothes they wear. Most of today’s superstar athletes rely on clothing and equipment enhanced with nanotechnology. What is nanotechnology? Nanotechnology is the science of the super small—microscopic even. One nanowire is 1,000 time thinner than a single strand of human hair. Now that is SMALL! Materials made with nanotechnology are stronger, more durable, and yet lighter and more flexible.
Nanotechnology produces swimsuits that allow the athlete to glide through the water faster, golf clubs that hit the ball farther, and tennis rackets that flex more easily to provide the hard smash across the net. This innovative new technology has already been used in the Olympics. In 2008, swimmers Michael Phelps and Natalie Coughlin wore swimsuits that were created with nanofibers. These nanofibers are woven tightly so that the swimmer’s bodies become more streamlined (like a shark!) allowing them to glide through the water faster. In the 2014 winter Olympics, the U.S. speed skaters wore specially created vented suits (like the swimsuits—to reduce drag), and in the 2018 winter Olympics, the USA Snowboarders will be wearing snow gear inspired by the space program.
Nanotechnology is a cutting-edge science that is changing the world of sports—and in particular the Olympics— as we know it. Will you make nanotechnology part of your game?
The LZR Racer is a line of completion swimsuits manufactured by Speedo using a high-technology swimwear fabric. In March 2008, athletes wearing the LZR Racer broke 13 swimming world records. Much like other suits used for high competition racing, LZR Racers allow for better oxygen flow to the muscles, and hold the body in a more hydrodynamic position, while repelling water and increasing flexibility.

You would have to increase a carbon nanotube x100,000 to make it the size of a strand of hair.
