Let this book be dedicated to the chemists of the newer generation , who will not wish to reject all inferences from conjecture or surmise, but who will not care to speculate concerning that which may be surely known. The fascination of a growing science lies in the work of the pioneers at athe wery borderland of the unknown, but to reach this frontier one must pass over well travelled roads: of these one of the safest and surest is the broad highway of thermodynamics. -Ushbu kitob faraz yoki taxmindan kelib chiqqan barcha xulosalarni rad etishni istamaydigan, ammo aniq ma'lum bo'lishi mumkin bo'lgan narsalar haqida spekulyatsiya qilishni xohlamaydigan yangi avlod kimyogarlariga bag'ishlangan. Rivojlanayotgan ilm-fanning maftunkorligi noma'lum chegaradagi kashshoflarning ishida yotadi, ammo bu chegaraga erishish uchun yaxshi o'tgan yo'llardan o'tish kerak: ulardan eng xavfsiz va ishonchlilaridan biri termodinamikaning keng magistralidir.
