Quite recently then

I would be tempted to say a fortnight ago,but it happenned Thursday last...

So another cherry falls from the branch

Learn something new everyday,and use it in a sentence the next day...

Let me know how you get on with this:

The heat transfer coefficient is used in calculating the convection heat transfer between a moving fluid and a solid in thermodynamics. The heat transfer coefficient is often calculated from the Nusselt number (a dimensionless number). Below is an example where it is used to find the heat lost from a hot tube to the surrounding area.

You lost me at "me"...

Ok that was nasty, my apologies. not many people are into thermodynamics. Shame really 'cause tis a wonderful subject especially when you get under the sheets and see the temperture rise

and you don't even need a themometer..

Like hell you did.
