The levels of 14C present in a specimen can be measured in a variety of ways; however the invention of accelerator-based mass spectrometric techniques have drastically increased measurement accuracy, as it provides a count of the number of 14C atoms present in a sample.
It has been used to date specimens up to 60,000 years in age.
Pitching a story about a generic idea — a group of people losing money on their subprime mortgages, say — isn’t nearly as effective as finding one or two people experiencing that issue who can illustrate the broader idea.
So when pitching, make it clear that you’ve done enough research to gather the basic details of your story — who your character(s) will be, where the scene(s) might take place, what’s at stake.
By so doing, this case study demonstrates the compatibility of a city-state both minting its own coinage and possessing a formal political alliance () with Athens.
I begin the first half of the paper with the numismatic evidence.
When an organism dies, the intake of 14C ceases, and what was left in the organism begins a measurable disintegration.
Carbon-14 has a half-life of 5730 years (±40 years), meaning that (in accordance with the law of radioactive decay) it will take that length of time for half of the carbon present in an organism to decay into stable carbon isotopes.
You want to do enough exploring to make sure there’s a real story there, but you don’t want to sink too much time into it in case the pitch gets turned down.To that end, I do most of my preliminary research over email and the phone.I don’t start collecting tape until the pitch has been accepted.Intro from Jay Allison: For years, the incredibly versatile producer, Ari Daniel, has been visiting the Transom Story Workshop to tell students how to make a freelance living in public radio and related environs.He knows the Art of The Pitch, and in his Transom feature he now breaks it down for you. You’ve probably got a story kicking around that you want to report on the radio.
