Re: Models for Covid-19

Pressure or temptation (with bribes?). I struggle to understand the message - unless it comes from people with no moral spine.

Waiting to happen: The sunken ship, the explosives - and the huge threat to the north Kent coast
Some of the bombs are armed.

Nice area, BTW. The local quiet nature reserve was my and my husband's favourite hideaway before we blew up :-)

Re: x?

I suspect it's something to do with [$]\frac{d^n}{dx^n} x^n = n![$], but I don't see how it gives the above. [$]n[$] is an integer? BTW have you sussed out fractional calculus. Yes, n is an integer. As for the fractional calculus, we've decided to model those equations fully numerically in the end,...
