A poor scientist struggling with data analysis and visualisation.

comment Characteristic length for the diffusion equation (temperature)
I think $\kappa$ in this case is the thermal diffusivity, not thermal conductivity.

comment How do I explain to a six year old why people on the other side of the Earth don't fall off?
My 2.5 year-old gets that her grandma is my mum.

comment Can I estimate the long-term surface heat transfer coefficient based on a temperature difference between the air surface and ground surface?
Not zero, surely?? There is always radiative energy coming in, how can it be zero? Over a year or so the net effect is a constant, but it must be greater than zero? I'm sorry if I misunderstand something here... not a physicist.

comment Why does the milk frother on my coffee machine make so much noise?
@SF. I think the temperature must also play a part... not sure how much of a part though, perhaps only in its effect of the viscosity of the fluid?

So if I put a cup of water instead of milk I'll get a different noise or volume? I will try it.
