In centuries to come a body of a man or animal who lived and died in the 20th century would appear paradoxically of greater age since death than the body of a man or animal of the 19th century, and if the process of industrial use of fossil, therefore dead, carbon continues to increase, as it is expected will be the case, the paradox will continue into the forthcoming centuries.
To check on the method before applying it on various historical and paleontological material, Libby chose material of Egyptian archaeology, under the assumption that no other historical material from over 2,000 years ago is so secure as to its absolute dating.
When objects of the Old Kingdom and Middle Kingdom of Egypt yielded carbon dates that appeared roughly comparable with the historical dates, Libby made his method known.
It’s like they say in the hot-rodding world: It’s what’s under the hood that counts.
The $3000 RPM 9 Carbon is Pro-Ject’s “tuner” special and it’s been kitted out with three significant upgrades over the stock RM-9.2.
Of the three reservoirs of radiocarbon on earththe atmosphere, the biosphere, and the hydrosphere, the richest is the lastthe oceans with the seas.
The correctness of the method depends greatly on the condition that in the last 40 or 50 thousand years the quantity of water in the hydrosphere (and carbon diluted in it) has not substantially changed. The method depends also on the condition that during the same period of time the influx of cosmic rays or energy particles coming from the stars and the sun has not suffered substantial variations.
And, it is our intent to educate our customers, and the community at large, as best possible, as we strongly believe that the more engineers, designers, students, hobbyists and the public-at-large learn and understand about carbon fiber, the more widespread it's use will become.
When selecting a carbon fiber product or designing with carbon fiber, one of the most important considerations is knowing the direction of the property of interest.
