So, what do I mean by that?

So we ran all of these tests blocking the protein, and we saw this huge shift.

Something happened in the early morning hours of May 2nd, 2000, that had a profound effect on the way our society operates.

Last year saw a big political change in Japan.

No change.

Well, from Italy to Iowa, that's a big change.

To anyone considering NAND2Tetris, it's a tough journey, but you'll be profoundly changed.

Of course there are many exceptions.

This is a powerful tool of empowerment.

So again, the big question is what happens to c, to c?

Sometimes the greatest change brings about even greater opportunity.

But this last time, just coming round, right now, suddenly, there'd be huge changes in the environment, in the concentration of people, and it was just unbelievable, the amount of all the change in it.
