What better time to contemplate the conundrum that is zero than the start of a new year? Zero is a fairly new concept in human history and even more recent as a number. It wasn't until around the 7th century that zero was used as a number. That's when it showed up in the records of Indian mathematicians. Since then, zero has, at times, been met with some fear — at one point the city of Florence, Italy banned the number.
Today, scientists seek to understand how much humans truly comprehend zero — and why it seems to be different from other numbers. That's how we ended up talking to science writer Yasemin Saplakoglu in this encore episode about the neuroscience of this number that means nothing.
