Poor air quality, which can be influenced by a variety of fumes, chemicals and allergens, is arguably the leading cause of triggers for most asthmatics in urban areas. ↗

For under certain conditions the chemical atoms emit light waves of a specific length or oscillation frequency - their familiar characteristic spectra - and these can come in the form of electromagnetic waves only from accelerated electric quanta. ↗

It is more likely that more than a century will pass before we know the structure of the chemical atoms as thoroughly as we do our solar system. ↗

With this in mind, for some twenty years I have set myself as my particular task the experimental investigation of the connexion between change in the structure and change in the spectra of chemical atoms. ↗

I studied chemical engineering. I was a good student, but these were the hard times of the depression, my scholarship came to an end, and it was necessary to work to supplement the family income. ↗

This success led my theoretical group to the chemical reactivity theory, extending more and more widely the range of compound and reactions that were discussed. ↗

The development of a rational view of the nature of catalysis was thus absolutely dependent on the creation of the concept of the rate of chemical reaction. ↗

The physical fabric of the world had to be such as to enable that ten billion year preliminary evolution to produce the raw materials of life. Without it there would not have been the chemical materials to allow life to evolve here on earth. ↗
