'open' space

A mathematician, Paul Erdos declared "My brain is open!" at a conference. His announcement meant that he was ready to talk with anyone and discuss anything (in his case, of course, anything about mathematics) at any time.

I'm also ready to talk with anyone and discuss anything related to my interests in engineering, science, history and philosophy with my heart like him. Here is open just as live organisms. It's an open system that can enable us to communicate each other and make our own thoughts and voices. If we notice something good, we can take and share it. In many discussions, we can also change our thoughts and the world we live.
