John Smith started the day ear...

John Smith started the day early, having set his alarm clock (MADE IN JAPAN) for 6 am.

While his coffeepot (MADE IN CHINA) was perking, he shaved with his electric razor (MADE IN HONG KONG), and put on a dress shirt (MADE IN SRI LANKA), designer jeans (MADE IN SINGAPORE) and tennis shoes (MADE IN KOREA).

After cooking his breakfast in his new electric skillet (MADE IN INDIA), he sat down with his calculator (MADE IN MEXICO), to see how much he could spend today.

After setting his watch (MADE IN TAIWAN) to the radio (MADE IN INDIA), he got in his car (MADE IN JAPAN), filled it with GAS (from SAUDI ARABIA) to continued his search for a good paying AMERICAN JOB.

At the end of yet another discouraging and fruitless day checking his Computer (made in MALAYSIA), John decided to relax for a while.

He put on his sandals (MADE IN BRAZIL), poured himself a glass of wine (MADE IN FRANCE) and turned on his TV (MADE IN INDONESIA)...
And then wondered why he can't find a good paying job in AMERICA.

And now he is hoping he can get help from the president (MADE IN KENYA)?

Grote Reber

Died 20 Dec 2002 at age 90 (born 22 Dec 1911). U.S. amateur astronomer and radio engineer who self-financed and built the first radio telescope. He pioneered the new field of radio astronomy, and was the first to systematically study the sky by observing non-visible radiation. After reading about Jansky's discovery (1932) of natural radio emissions from space, Reber constructed a 9-meter dish antenna in his back yard and built three different detectors before finding 160 MHz signals (1939). In 1940 and 1944 he published articles titled Cosmic Static in the Astrophysical Journal. He was the first to express received radio signals in terms of flux density and brightness, first to find evidence that galactic radiation is non-thermal, and first to produce radio maps of the sky (1941).«
