A rocky road, a wonderful world.

Sending signals with puffs of smoke, birthday balloons and floating feathers, we hoped everyone would come to our celebration.

We were celebrating it being two days after the day we last celebrated. The days in between were good, but when a couple of days pass we get hungry for more.

Then, well sometimes, we enjoy the calm of a week or two and perhaps a couple of months of near-silence.

Time to enjoy every atom that moves around us.

It’s so, then, really time to get familiar with particles and how they interact.
