Thread: Caffeinated Physics...

Nice Mal!


Java "Fun with science!" phile

Fun indeed mate...

Mal.

I'd always thought there wasn't enough discussion of Reynolds number when talking about coffee. And a Nature paper no less!

Indeed...

I never expected RN to be mentioned in a coffee article, especially after studying Aeronautical Engineering many years ago and then of course, flow characteristics through pipework, etc...

Just goes to show....

From Cosmos magazine.

"If you pour coffee into warm milk at just the right speed, the laws of physics will make the two liquids arrange themselves into an elegant series of layers shading from white to dark brown, according to a new study that may have applications far beyond the barista’s realm."

And then you need to stir it to avoid drinking warm milk followed by straight espresso instead of a latte.... I don't know where you keep finding all these gems Yelta. I only hope it's not by trawling through cosmo each month

...

The article I posted in the beginning is the origin of this story Yelta...

Mal.

Hhhhmmmmm....Perhaps that's why the threads were merged?


Java "" phile

Evening Mal, I noted the similarity before posting, however started a new thread as the Cosmos piece was somewhat lighter and little easier to comprehend (to us non scientific types)

Interesting Publication dates, perhaps Cosmos got hold of the Nature Communications paper prior to publication and decided to dumb it down.
