I'm a physicist modeling air pollution and global warming.
Of course, I spend most of my time programming.

comment What is scientific relation between body weight and backpack weight in mountain climbing?
I would suggest that whether climbing, mountaineering, or backpacking, the goal is to have the weight from your pack resting on your hips and not your shoulders. That really makes all the difference.

comment What is scientific relation between body weight and backpack weight in mountain climbing?
I have climbed up the Northwest face and hiked the John Muir trail up Mount Whitney, and this is just my experience. @RoryAlsop is totally right, there are too many confounded details. The only important factors are fitness and experience. Good luck.

comment Can I use my leather jacket to go to ski?
If you fall, you will get soaked. Also, ski pants are seriously a must.

comment May hiking in Eastern California
@gerrit I live in the area, before I answer: do you want to hike for one week at a stretch, or do a few smaller 2-day hikes?

comment How to create campfire which will burn overnight?
When building a campfire, if you set the logs further apart they get more air and burn faster. If you set the logs closer together, they get less air and burn slower.

comment What type of knife should I carry while rock climbing?
What are you looking to cut while climbing? Is this for opening dried food packs while on a porta-ledge, or for cutting rope? I'm not sure I understand.

Can you describe to me a climbing situation in which you need to cut rope? This is not something I have run into.

comment Safe Way to Mark a Carabiner
That is an interesting point. You didn't exactly answer my question though. Is there something that would work?

comment Can you keep your feet warm in ski boots on a very cold day?
Personally, I buy ski boots to fit well OVER two thick pairs of socks. That way my feet stay warm. Why did you not do this?

comment What’s the difference between a B and a T ice axe?
I'm more of a rock than an ice guy. What do you mean by "technical"? Do you mean Real climbing as opposed to mountaineering? Or do you just mean harder ice climbing?

comment Art supplies on backpacking trips
I frequently wonder the same thing about taking my camera backpacking/climbing. But that is a lot of really fragile, expensive equipment.

comment Lacing materials for huaraches
Can you post photos of your huaraches and their current laces? That would be awesome.

Kudo's. I wanted to add that all the important knots for climbing are listed here.

comment What hand and finger exercises help with climbing?
Use a hangboard/fingerboard. Do a 20-minute exercise twice a week. Be consistent. Don't climb the day after a real 20-minute handboard routine (to exhaustion).

comment What is the fastest style of sled?
My concern in accepting your answer is two-fold: (1) Wouldn't all sleds be faster if you wax them down? and (2) I thought these sleds were only fast on really hard-packed snow, but were kind of useless on deep, fluffy snow?

comment Methods for taping hands, wrists, and fingers for climbing?
@Mr.Wizard I have always wondered: Is it possible to make the above crack glove without pulling out a ton of hair? I'm a dude, and the hair on my wrists and hands is thick. I've never made a crack glove because I figured it would tare out a TON of hair to take on off. Yes/no?

comment What good factual books have you read on an outdoors topic?
@DonBranson I almost forgot that. I added it to my post. That is important information.

comment What good factual books have you read on an outdoors topic?
@DonBranson Exactly. And good for you. Please notice what I said about 2000 pages. And the book is dense, too. I am also taking some CPR and wilderness first-aid classes at my local REI this month. If you live by a University, they frequently have the same classes. Stay safe.

comment What is the fastest style of sled?
Well, technically you are totally correct. Though I feel like that means I need to edit my question some how.

comment How to avoid pendulum descent when belaying?
It sounds like your belayer was going to fast at the start. If you are on overhung, it helps to have some time for the climber to lower their body in a controlled manner into the open space below them. If you are not on overhung, this should never happen, as long as the climber can slowly walk their legs down the wall.
