Scientists in different disciplines don't speak the same language. They publish in different journals. It's like the United Nations: You come together, but no one speaks the same language, so you need some translators.

There is no such thing as the United Nations.

If the United States commits to the goal of reaching Mars, it will almost certainly do so in reaction to the progress of other nations - as was the case with NASA, the Apollo program, and the project that became the International Space Station.

I'm a member of the US committee o the United Nations.

The mandate you go with is intimidating and also is a source of respect that you gain, because you have come with this mandate from the United Nations.

The United Nations is an indispensable but deeply flawed organization. It is valuable to the United States, and the United States is invaluable to it. We need to reform it.
