If One Introduces The Concept Of Energy

If One Introduces The Concept Of Energy Of An Earthquake Then That Is A Theoretically Derived Quantity.

As Seismologists Gained More Experience From Earthquake Records, It Became Obvious That The Problem Could Not Be Reduced To A Single Peak Acceleration. In Fact, A Full Frequency Of Vibrations Occurs.

In Every Area Of The World Where There Is Earthquake Risk, There Are Still Many Buildings Of This Type; It Is Very Frustrating To Try To Get Rid Of Them.

Don't Wait For Extraordinary Circumstance To Do Good; Try To Use Ordinary Situations.

My Main Point Today Is That Usually One Gets What One Expects, But Very Rarely In The Way One Expected It.
