Old school dating

Posted in Aris's Birmingham Gazette, 7 March 1785:

TO THE FAIR SEX

A PERSON of Character, 26 Years of Age, of a genteel profession, and of moderate fortune, wishes to engage in the Hymenial State, with an agreeable, good-tempered LADY, in AGE inferior to himself, in FORTUNE equal, or nearly so; but, in GOODNESS, as superior as Emulation CAN excite. - One having no Objection to enter a Public Line or Shop-Keeping, would be preferred; And it would be no Object of Denial, if she happens to have a fortune of MORE Capital than required. - Any Lady this may suit, may depend on a punctual Answer by addressing (Post paid) for T. H. to be left at the Printers till called for.

It's such a pity we will never know if T.H. found his perfect woman!

Could all our carbon dating be wrong?

I am no chemist or physicist, just wondering what the science buffs amongst you think after reading this article? What are your thoughts on the potential implications for archaeology?

Here's a quote from the article:

Carbon-14 has a very defined half-life of 5730 years; i.e. it takes 5,730 years for half of a sample of carbon-14 to radioactively decay into stable nitrogen-14. Through spectroscopic analysis of the ancient organic sample, by finding out what proportion of carbon-14 remains, we can accurately calculate how old it is.

But as you can see, carbon dating makes one huge assumption: radioactive decay rates remain constant and always have been constant. If this new finding is proven to be correct, even if the impact is small, it will throw the science community into a spin.

Interestingly, researchers at Purdue first noticed something awry when they were using radioactive samples for random number generation. Each decay event occurs randomly (hence the white noise you'd hear from a Geiger counter), so radioactive samples provide a non-biased random number generator.

However, when they compared their measurements with other scientists' work, the values of the published decay rates were not the same. In fact, after further research they found that not only were they not constant, but they'd vary with the seasons. Decay rates would slightly decrease during the summer and increase during the winter.
