Carbon dating flaw

When I have asked an audience this question they have looked at me incredulously and said, “Starting time?” They realize that you cannot know how long the swimmer took unless you knew the time on the wristwatch when the race started."Paper spotlights key flaw in widely used radioisotope dating technique." Science Daily. Engineers have developed a new technique to test for a wide range of micropollutants in lakes, rivers and other potable water sources that vastly outperforms conventional methods. Sulfur and iron accumulation has once again been found in wood samples from old shipwrecks in the Baltic Sea.

For example, strontium-86 has 38 protons and 48 neutrons, whereas strontium-87 has 38 protons and 49 neutrons.

Many people assume that the dates scientists quote of millions of years are as reliable as our knowledge of the structure of the atom or nuclear power.

And radioactive dating is so shrouded with mystery that many don’t even try to understand how the method works; they just believe it must be right.

Keep that in mind when you think about working out the age of something. Actually, knowing the starting time is still not enough.

During the race you have to watch the swimmer and count how many laps he has swum so you know that he has done 1,500 metres.
