I have found it
Usage of "eureka" in English has also come to signify the sudden burst of elation or enlightenment which comes with a discovery. California adopted the word as its state motto in 1849, preparatory for the occasion of the state's joining the United States; it is described in the definition of California's Great Seal as "the Greek motto "Eureka," (I have found it), applying either to the principle involved in the admission of the State, or the success of the [gold] miners at work".
