I'm sure the service is extremely useful to the computer literates, but I'm not one of them. Although it's not rocket science, I'm old fashioned and was hoping to talk to someone and walk me through it over the phone. Not a bad experience though...

It has been a little difficult at times but I am computer illiterate so if I can do it or manage to figure it out I think it’s safe to say anyone’s name. I ha it has been a little difficult at times but I am computer illiterate so if I can do it or manage to figure it out I think it’s safe to say anyone’s name. I Got a few other features would be nice. Texutered, patterns of the paper texture already patterns of the paper also cut and paste; As well as Cut n pastes features.

How far back can radiocarbon dating go?
C (the period of time after which half of a given sample will have decayed) is about 5,730 years, the oldest dates that can be reliably measured by this process date to around 50,000 years ago, although special preparation methods occasionally permit accurate analysis of older samples.
How far back can radiometric dating go?
There are a variety of radiometric dating methods that can go back much farther than that. For example, samarium-neodymium dating can go back billions of years and get precision to within less than twenty million years.
How accurate is radiometric age dating?
The precision of a dating method depends in part on the half-life of the radioactive isotope involved. For instance, carbon-14 has a half-life of 5,730 years. After an organism has been dead for 60,000 years, so little carbon-14 is left that accurate dating cannot be established.
How far back can we date?
There are a variety of radiometric dating methods that can go back much farther than that. For example, samarium-neodymium dating can go back billions of years and get precision to within less than twenty million years.
How far back can potassium argon dating go?
Potassium-argon dating is accurate from 4.3 billion years (the age of the Earth) to about 100,000 years before the present. At 100,000 years, only 0.0053% of the potassium-40 in a rock would have decayed to argon-40, pushing the limits of present detection devices.
How is radiometric dating done?
Radiometric dating is a method used to date rocks and other objects based on the known decay rate of radioactive isotopes. The decay rate is referring to radioactive decay, which is the process by which an unstable atomic nucleus loses energy by releasing radiation.
How accurate is radiocarbon dating?
To radiocarbon date an organic material, a scientist can measure the ratio of remaining Carbon-14 to the unchanged Carbon-12 to see how long it has been since the material's source died. Advancing technology has allowed radiocarbon dating to become accurate to within just a few decades in many cases.
Is carbon dating actually accurate?
To radiocarbon date an organic material, a scientist can measure the ratio of remaining Carbon-14 to the unchanged Carbon-12 to see how long it has been since the material's source died. Advancing technology has allowed radiocarbon dating to become accurate to within just a few decades in many cases.
