Text 36 A
Choosing Chemistry a Profession
The students enrolled for a course in general chcmistry can and do ask themselves the question: “What real use is this course to me?”
The answer for the student who intends to major in a scicncc is obvious. His hope is to derive information to use as a tool in making a living.
There is an answer, however, beyond the fact that the coursc may be required.
The period of the teens and early twenties is a crucial one in life. It is during this time that the student is approaching intcllcctual and emotional maturity and is physically in his prime. It is also at this time that he is striving to discover what meaning and purpose there may be in life; he is about to comc to the conclusion that other people actually exist as important entities rather than adjuncts to his personal welfare; and it is now that with freshly opening eyes he seeks to put the world into an understandable perspective. At no other time than this is the mind so supple and so capablc of amendment.
If there is any real lack peculiar to the age, it is the lack of all kinds of experience. Years at college should provide the social and personal cxpcricnccs to fill this gap. The first year at collcgc may also be one of keen disillusionment, as the student discovers that the professors arc not the gods who hold the final answers to all being and meaning in their august persons.
The particular and important scrvicc that the chcmistry tcachcr can make is the contribution of facts to the building materials of personal philosophy. Certainly, the best and finest house requires the most materials for its construction, and the most complete and satisfactory of personal philosophies must be housed in a framework of fact, however gaudily it may later be dccoratcd with the furniture of speculation.
This wc can do: provide the student with some ideas conccming the structure of matter, the finitcness of the kinds of matter, and the changes matter can undergo. To this, it is hoped, may be added an appreciation for the orderliness of nature and simple laws which govern the infinite proliferation of her works. One should be careful to present known facts as the facts of experience and experiment and stress the idea that the guiding light of theory must be confirmed by the bench of physical manipulation.
