We think that it is the best scientists working in the frontier fields of science who are best able to judge what is good and what is bad - if any - in the application of their scientific research.

This simple idea served to provide information on the geometrical shape of reacting molecules, and I was able to make the role of the frontier orbitals in chemical reactions more distinct through visualization, by drawing their diagrams.

The frontier orbital approach was further developed in various directions by my own group and many other scientists, both theoretical and experimental.

We pray that every field of science may contribute in bringing happiness - not disaster - to human beings.

Personal success means nothing if it isn't aligned with the success of the team. I consider myself to be a team player more than anything else.

Success soon palls. The joyous time is when the breeze first strikes your sails, and the waters rustle under your bows.

From a distance, the American political system is a remarkable success. We have accomplished the peaceful transfer of power for more than two hundred years, and that's unmatched by any civilization in human history. Up close, our political system still has all the ugliness and bad actors that you might suspect.

If you can feed your family, give them an education, then you are a success.
