Halloween: from a 2,000 year-old tradition to a modern festivity

Pizza and the formula of the universe

My Daddy taught me that the universe has been expanding for a long time now; apparently it has been doing so ever since the Big Bang. Even Einstein said that, so it must be true. This means that before I eat a pizza I should at least wait 10 minutes before I start, because during that time my pizza is going to expand and then the volume of my meal will have increased whereas the calories won't. Additionally, since my stomach will also have expanded, it won't even trouble me to eat an even bigger volume of pizza.
