It's were the branches come out.

It was so hot in Scotland today, I had to take my shirt off while chopping the logs.



that's a Granny knot!

Beeswax: Natures petrol tank sealant.

When things are in 3D, is it always the same three dimensions?

Before the knots become solid they begin as fluid, the circulation direction is altered to flow around where the branch has altered the flow path so now we have flow going in two directions and more and more tubular structures are manufactured to accommodate the flow, eventually becoming redundant heart wood leaving an indelible twisted grain pattern showing the route the sap flow has taken.

Great picture of the knotted tree btw. Impressed.
Science is continually evolving. Nothing is set in stone. Question everything and everyone. Always consider vested interests as a reason for miss-direction. But most of all explore and find answers that you are comfortable with
