How many half-lives does it take for 6 x 1023 atoms of a radioactive nuclide to completely disappear?

You have to give the half-life of the radioactive substance, which can range from microseconds to billions of years!!. Then, we can easily figure out how long would it take to completely disappear.

half life of 1 day

A(0) =[6 x 10^23) x 2^-(d/1), solve for d

A(0) =Log[6 x 10^23) / Log(2)

d =~78.9893 days - when you will have 1 atom left !!!.

Now for an advanced theory: What is the half-life of a Blarney Brain? 

 

This is a very complex theory, because the decay rate isn’t constant, and the diaphanous molecular structure phases between alternate universes. Some of these alternate universe realities intersect with this one. The intersections produce quantum effects, which are identifiable as quantum variants of the virulent Contagious Dumbness Disease (CDD), Batshit-Stupidity (BS), and Moronic Idiot disorder(MID).

 

The above three posts represent generalized examples of these three variants. 

 

I leave it to the reader to  determine which belongs to whom.

Meanness is in my genetic code. It’s in the nature of chimps to throw poo at offensive persons.

If you can evaluate who is mean in this scenario, then you will know who’s truly mean and why.

 

A restaurateur serves various meals to his patrons. On the surface, most of his food seems edible, but unknown to most of his patrons he often laces the fare with batshit. Some of the patrons eat this food, without complaint, seemingly unaware of the special ingredient; others murmur about it but don’t really complain.

 

A chimp comes into the restaurant, and the maitre dee serves her a meal laced with the special ingredient. The chimp has a superior olfactory nervous system and immediately recognizes the special ingredient and throws the laced food at the restaurateur. 

 

A patron in the restaurant asks the chimp why she is so mean. 

The chimp says, “I throw batshit-laced food at one person--the same person who serves it to hundreds.  Who is mean?”
