An amazing dog

There was this ad posted on the office window of an accounting firm :

"HELP wanted. Must be able to type 70 words per minute. Computer literacy is required. Must be bilingual. EQUAL EMPLOYER."

So there was this dog ambling outside the office. It noticed the ad and shuffled into the office to apply for the position. The employer took one look at the dog, shook his head and said "But I can't hire a dog."

The dog pointed at the words EQUAL EMPLOYER on the ad. So the employer said, "OK, can you first type this document?" and gave the dog a letter. The dog typed everything correctly and neatly without a mistake at a rate of 70 words per minute.

Flustered, the employer then said, "Then, can you put these figures into spreadsheet and make a program to feed it into the mainframe, process it in the General Ledger Module and give me the Balance Sheets and Profit and Loss Statement?" and gave the dog some documents. The dog completed the spreadsheet, the program, the Balance Sheet and the P/L statement promptly & correctly.

The employer shook his head, pointed at the ad and said, "But are you bilingual?"

The dog said "Meow!"

Alfred Werner

Born 12 Dec 1866; died 15 Nov 1919 at age 52.Swiss chemist whose founding research into the structure of coordination compounds brought him the 1913 Nobel Prize for Chemistry. He demonstrated that stereochemistry was not just the property of carbon compounds, but was general to the whole of chemistry. His theory of chemical coordination (1893) recognized that many metals appeared to show variable valence and form complex compounds. Certain metals, such as cobalt and platinum, were capable through their secondary valences of joining to themselves a certain number of atoms or molecules. These were termed by Werner “coordination compounds.”and the maximum number of atoms (or “ligands”as he called them) that can be joined to the central metal is its coordination number.
