Archaeologist Laughed At

An archaeologist publicizes his find, a coin marked 649 BC, but is laughed at by his peers. Why?

No coins were ever marked BC because the BC / AD dating system wasn’t even devised until 525 AD. And it wasn’t widely used until after 800 AD.

I Am Both Safe and Secure

As a whole, I am both safe and secure.
Behead me, I become a place of meeting.
Behead me again, I am the partner of ready.
Restore me, I become the domain of beasts.

Stable. A table is a place of meeting. Able and ready is a common phrase, and a stable is where beasts reside (beasts of burden, not beasts like the one in Beauty and the Beast who lived in a glorious castle but the west wing was forbidden to enter until Belle…I’ve said too much!).

I Am Worthless

I am worthless, yet when added to others I add worth.
I confounded the ancient Greeks, yet I changed men’s understanding.

What am I?

0 (Zero).

Zero is nothing, yet when you add zeroes to a number like 1, it becomes 10, 100 or 1,000.

The ancient Greeks did not have a name for zero and did not use a placeholder. They seemed unsure about the status of zero as a number, philosophizing about how nothing could be something. Once zero was added, it allowed for more mathematical understanding.
