Wise words, Jim. In the Netherlands, it has been freezing for a week.
All water surfaces are covered in ice: I haven't been paddling for a
month. Even worse, I sold my seakayak, while the new boat I have in mind
will not be imported until early spring. 

The temperature here is rising now: A cold, clear blue sky has been
replaced by icerain. Later this week, when all the ice is gone, I should
do some paddling in my guest boat, that will surely improve my mood.

Melissa: I think you add some valid points to my rant on the beauty of
physics. I'd like to get together with you, have a few drinks, and have
a long discussion on what "learning" is, on different ways to appreciate
music and on the different ways to gather "specific knowledge". However,
I think that discussion does not belong on paddlewise.

Cheers to all, happy paddling, 

Niels.

G'Day,

Just got back and saw a heap of debate on the gravity topic - saw several
credible reasons why it takes energy to work against gravity in moving
forward over a wave - thanks.

This reply is late because I was down south being taught that it sometimes
takes less energy to roll under a breaking wave than climb over it. Came
face to face with a jelly fish while upside down in the surf - blew that
roll!! :~)

But what a discussion!! Thanks everyone - especially Matt, Nick, Niels and
Melissa,

All the best, PeterO
