First example Performance driving

A prototype example is the famous McMurry coupling of carbonyl compounds to alkenes (Scheme 1) [4]. The very high stability of the accumulating titanium oxides constitutes the thermodynamic sink which drives the conversion but demands the use of stoichiometric or excess amounts of the low-valent titanium reagent [Ti]. Only recently has it been possible to elaborate a procedure that for the first time enables us to perform intramolecular carbonyl coupling reactions catalyzed by titanium species [5]. 

Protocol 2. Illustration of the typical behavior of a rat that acquired the glass-cylinderseeking drive within 40 days, being trained daily. The rat, whose training started on January 21, displayed for the first time the typical signs of boredom on June 3. The protocol shows, as an example, the normal performance of the rat on April 1. The appearance of boredom and its elimination by changing the environment is shown on June 3, and a repetition of this experiment more than one month later, on July 8 ... 

It is possible to invoke examples about the way the human brain works and from IT to illustrate that Zen and existentialism (see below) have an essentially scientific and biological justification. Consider this. Non-automobile drivers can substitute travel by subway train, walk routine, or other forms of transport to work. Drivers making their daily trips to work often barely remember the journey. Weren t they paying attention Wasn t that dangerous Consider first that these drivers must have made many intricate decisions, and performed many complicated operations, successfully. They switched lanes in a complex maneuvers and slowed down to let pedestrians stroll across roads. To perform such tasks many times a week, we take them in our stride, or we should say behind the wheel. Consider that if the unexpected had occurred, the driver would have quickly become alert and dealt with it soon enough. However, if the driver had been paying attention to every minute detail, that definitely would have made the trip dangerous, as this is exactly what happens the first time that we ever drive.
