Danger experience

Davy s research was to make him famous, not because he performed dangerous experiments, but because he discovered a new recreational drug. In 1800 he published a 580-page book titled Researches, Chemical and Philosophical, Chiefly Concerning Nitrous Oxide, or Dephlogisticated Nitrous Air, and Its Respiration in which he discussed his discovery of, and researches on, laughing gas. Describing its effects, Davy wrote ... 

The art and engineering of propellant and explosive manufacture consists in finding suitable combinations and treatments of sohds that wiU produce a stable compound that wiU not ignite until desired and wiU then bum with the appropriate rate to produce the desired blast wave or thmst.

I consider myself to be sort of a preppy hippie. I eat organic but can t be bothered to join the health food co-op down the street. I shave under my arms but don t wear anti-perspirant. I wanted a natural birth, but I didn t want to do it at home, and I didn t want an audience. So while there were parts about going to a birthing center, with all its alterna-ness, that didn t feel exactly me, I wanted to get medical attention from people who believe that having a baby without drugs is normal and healthy—not a dangerous experience that could turn deadly at any moment. 

This is a very good Australian film about MCS and the environmental consequences of countless untested, potentially toxic chemical substances circulating in our surroundings every day.

Dangerous experiments were part of the fun. 1 escaped several serious accidents in my basement laboratory, but my right hand was badly burned by the white phosphorus bomb I had concocted. 

The application technique must be flawless and in keeping with the particular procedure for each peel, appropriate to the patient s skin type and the results expected. The doctor must be aware of and acquainted with the risks of complications and the means to prevent and treat them. It is better to avoid complications through prevention rather than treat them. Each patient is different and each peel must be suited to each patient, which in no way means trying dangerous experiments with different formulas on a case-by-case basis. On the contrary, it is a matter of choosing among tried and tested treatments the one that is most suitable for the patient s skin structure and that will give the best results with a minimum of inconvenience. For example, the practitioner should be able to decide whether it is... 

The fortunate outcome of what had been a dangerous experiment obviously made a huge impression on Fleming, because he immediately contacted friends in the government and a Penicillin Committee was soon established. The pharmaceutical industry was finally galavanised into action, and pencillin production began in earnest. 

The new edition is aimed more to be a laboratory manual than a textbook. With this aim in mind, the text has been rearranged and shortened. Furthermore, dangerous experiments and those involving carcinogenic materials have been removed.
