FASCINATING FACTS
The keynote speaker at the CARSEF awards ceremony was a principal engineer from Intel. He provided some very interesting facts...
-
In the scientific community, the generally accepted age of the earth is 4.5 billion years. To try to understand that number, consider all that has occurred in the last 1350 years of our civilization. That entire
span is the equivalent of 1 second of the earth's total age.
-
The first microprocessor masks were (initially) created manually by cutting a stencil in rubylith (If you are too young to know what rubylith is, see this discussion and picture on Answers.com: http://www.answers.com/topic/intel.) The first microprocessor, the 4004, had 2,300 transistors. Today, a 1/2-inch square microprocessor has millions (or was it billions?) of transistors.
-
The circuitry patterns of a microprocessor are so small that they cannot be seen with even the strongest optical microscopes in the world. These patterns are literally just a few atoms deep.
If you weren't part of CARSEF this year, make plans for next April. Not only is an interesting experience, the papers range from very poor to excellent, you always learn something. The imagination, scientific exploration, and writing skills of the winners is awesome!
