3 million and growing, we (the US) are still number one.

One of the main features of "exponential" is that it does not matter how low the level is at which you start, the water still gets above your head very quickly.

It has been said that only one person in ten really understands exponential.
There is an old story, if you put bacteria in a test tube, and they double in numbers every hour, such that they will fill the tube to the top after fifty hours. Question how much of the tube is full after forty eight hours ? You don't need to work it out it is only one quarter. In other words the tube is nearly empty, three quarters clear after forty eight of the fifty hours are gone. It catches up fast at the end.

@Fernapple exponential...

Yes, it increases by certain factor... Very different from percentages...

@Cutiebeauty yes, get 100 pennies, start with one, double it each time....when do you run out of pennies? How many pennies will you need to keep doubling for just 30 days?
This virus does not merely double! Be afraid, be very aftraid

@AnneWimsey 30 days of doubling pennies.. I'd say about 20mil dollars worth...

@AnneWimsey you'd run outta pennies in about seven days

@Cutiebeauty waaay more!
