An IT student is walking along with his bike when another IT student walks up to him and goes “Nice bike. Where did you get it?”
The first student says, “The other day, this beautiful woman ran up to me with this bike, threw it on the ground, ripped off all her clothes and said ‘Take anything you want!’”
The first student says, “So I took the bike”.
The second student says, “Good choice. The clothes probably wouldn’t have fit”.
Otto WallachBorn 27 Mar 1847; died 26 Feb 1931 at age 83.German chemist awarded the 1910 Nobel Prize for Chemistry for identifying terpene compounds. His interest began began by analyzing fragrant essential oils - oils removed from plants by steam distillation, with industrial uses - and started research into determining their molecular structure. Wallach succeeded in determining the structure of several terpenes, including limonene, in 1894. He showed that terpenes were derived from isoprene, C5H8 - his isoprene rule (1887) - and therefore had the general formula (C5H8)n. Limonene is thus C10H16. Terpenes were of importance not only in the medicine and perfume industries, but also as a source of camphors. It was also later established that vitamins A and D are related to the terpenes. |
