It takes another 4,460,000,000 years for half of the remaining sample to decay into Pb206 and then another 4,460,000,000 years for half of what’s then left to decay, and so on.
The time it takes for half of a sample to decay is called a “half-life.” By measuring radioactive half-lives, by measuring how much parent and daughter are present in any given specimen, and by making certain key assumptions, scientists believe they are able to accurately determine the age of a specimen. The question is what are the underlying key assumptions and how reliable are they?
Employers are expected to close the loop when someone sends them business correspondence, which is what a job application is.
With online dating, there’s more of a cultural norm (among most people, at least) that if you’re not interested, there’s no need to respond to say that; it’s okay to just delete the message.
It feels different, because it feels more like I’m rejecting a person, well, personally, rather than saying they aren’t the right fit or we had more qualified applicants. I do indeed think the etiquette for rejection in different in these two situations: It’s much more acceptable not to reply to messages from would-be suitors on online dating sites than it is for employers not to reply to job applicants.
I also think I would get more pushback of the kind hiring managers sometimes get when we reject an applicant. Part of it is just a difference in conventions — the professional conventions for hiring are different than the conventions for online dating.
Question: "How does radiometric dating fit with the view of a young earth?
" Answer: Radiometric dating does not fit with the “young earth” view.
The science that studies human cultures is called anthropology.
It is a discipline that deals with the origins and development of human societies and the differences between them.
Each of these is basically an independent science, although specialists in one field frequently consult and cooperate with scholars in the other.
Physical anthropology is generally classified as a natural science, while cultural anthropology is considered a social science.
Part of it, too, is that there’s more of an understanding (or at least there’s supposed to be) that hiring and applying for jobs is, well, business not personal.
