Is there a branch of science that draws your interest more than others?

Earth Science. It's hard to explain my fascination and urge to learn more. Maybe it started when I saw a beautiful formation like the Grand Canyon and I wanted to know how it got there.

I used to sit around all day and try to figure ways to reduce drag, friction, and any other way to increase the performance of a 1973 Yamaha MX360 racing motorcycle. In one summer, I went from an also ran to bumping wheels with America's top points novice class flat tracker. 

  Geography, I can’t exactly put it into words what fascinates me about it, but I find it a interesting as all get out. 

How about you?

Probably biology because it has such a profound effect on how things work here on the land.
And it acts like a manual for helping keep my own body healthy.
The anatomy and physiology of plants affects orchards, veggies, weeds and native forest regeneration.
The types of grasses affect the health of the horses.
All the plants affect the wildlife.
Insects play a vital role in the lives of the plants, and affect the health of us all.

Having been a breeder and trainer of horses, I needed to understand how their bodies (and minds) worked for the sake of nutrition, fitness training and numerous other tasks. I sometimes needed to do minor bits of surgery if a vet was not available. And I've done my fair share of vet nursing. At one point, I did a week-end prac in equine anatomy run by Dr Deb Bennett. We did a complete anatomical autopsy on a horse that had been euthanised due to founder. Emotionally, it was hardest seeing the freshly dead body; terribly sad to see such a beautiful animal had to die due to the ignorance of his owner. Once the skin was off, it was more like dealing with meat, much easier to do the work.

Geography and meteorology and climate have been important as well. The plants and animals can't be what they are without the influence of these.

As time went by, I found everything so interrelated.
Plants and animals depend not just on the simple mechanics of their bodies, but on biochemistry.
Biochemistry is dependent on chemistry, and chemistry on physics.

I guess with me, it starts at the practical level of wanting to understand and work well with the natural world around me, but then in goes beyond that and becomes a fascination in its own right.

That said, I'm an ignoramus. Nothing worse than someone who knows a little. I have no expertise in maths which severely limits what I can understand.
I'm more a consumer - I love the documentaries, articles in Scientific American, and whatever I can find online when I have a question. My go to sites for answers are the universities. They all have their course material online now, and one can access small bits of it for free. Being at SCU at the moment, I get access into almost all unis.

Geology, but I have a broad appreciation of the natural sciences generally.

Also Engineering - which can be defined as applying scientific laws to practical purposes.
