  1. Migl, that is easily countered. Just ask the person posing such a question to provide a definition of "biological traits of a man/woman" that works in all cases.
  2. 1. Expose them to the fact that someone disagrees with them. People with those kinds of beliefs have often spent most of their lives surrounded by people who unquestioningly think the same. 2. Abandon all hope that you can actually alter their belief, because that's what it is: a belief, not a hypothesis. 3. Focus on exposing people who are not yet entrenched to a variety of perspectives. This guy probably wont be convinced, he may gradually find himself in a less aggressive stance, or may not. Hope for his children remains.
  3. Balancing cost and benefit of trash clean up

    Yeah, I can see the benefits of that approach. Maybe im wrong, but I feel like my circumstances have some additional hurdles. The organized group effort sounds good for a city park, but im dealing with more of a wooded area out in the hills. I feel like one (particularly me) would have a hard time coordinating a group to go out there, trek through poison oak, and gather trash in hard to reach, off-trail locations. Especially without trampling a lot of flora. The supervisor I report to knows that I've been hauling tires out with a backpack for the better part of 2 years and has yet to say "hey man, why dont you just get em to the trail and we'll come get em with the 4 wheeler?" Or any similar offer. He said cars are just a no go, and I shouldn't touch buried items. He also said hes had permits in to deal with similar items for about 5 years... My confidence is low. I am also interested in learning about it anyway, even if most of it should be left to the pros.
  4. My favorite local park is unfortunately place below a road, which has turned it into a dumping ground. I have spent a considerable amount of time, money, and effort removing as much of the trash as I can, but the process raises some questions about which items are worth the effort. Some items seem like they have a pretty low impact other than being an eyesore, like glass. other items require a disproportionate effort due to size, weight, and location. The park service has told me that some of them are not worth removing because the impact of digging them out, and erosion in hauling them out of the park outweighs the environmental impact of leaving it there, like car chassis. I have tried for a while to find a resource to help me understand the impacts of various materials so I can better gauge the pros and cons, but I haven't found anything. Examples of the kinds of questions im trying to answer: Does glass actually have any impact? What about aluminum cans? I know tires are toxic. Is there a point where the process of removal (disturbing the creekbed) out weighs their impact? If a car battery has long since rusted out, and has been sitting in a creek for years, is it still a hazard, or have the dangerous chemicals probably all washed out? Information, or tips on where I could read up would be very appreciated.
  5. Help me test my cryptogram?

    It sure is. I believe that should be an H. Thanks! You were able to decode it with just the first one?
  6. Help me test my cryptogram?

    Making a cryptogram as part of an extended puzzle/treasure hunt. I know what it says, and the only other friend I have that I think likes cryptograms is who I'm making it for.

  7. Focusing light

    I make a bit of a habit of posting silly-ass ideas like this on various forums. Fairly often people who seem more informed than me tell me that its not going to work the way I want it to and "heres what you would really need to make that happen". I usually do my best to respect the fact that they seem to know what they are talking about, and adjust my plans closer to what they say. But if im being honest, the fact that you are both the dude selling the flashlights, and the dude saying the flashlights are the solution, has damaged my trust a bit, and my reading elsewhere is leading me to believe it shouldnt take that much tech or that many lumens. So I'm going to try to direct this back towards the physics of the question. If I build a box, sphere, whatever shape enclosure from whatever seems appropriate down at the ol' hardware store (read:dirt cheap) and pick up a pile of whatever solar powered landscape lights I can find (read:dirt cheap) and plug them all into said enclosure somehow... I figure I now have a somewhat respectable light source. However, its all bouncing around at weird angles, and most of it is going to end up absorbed by the enclosure rather than directed down my aperture toward the target. I realize with passive optics its not really going to be possible to direct all those weird angles where I want them, but are there means to significantly improve the amount that ends up going the right direction? Via a properly shaped reflector and/or lens setup, could I increase the output through the aperture 3, 4, 10 fold?
  8. Focusing light

    I dont know what many of those words mean, but it sounds good. To give me a feel for scale... 3.5 amps, if I want the light to stay on all night, lets say 10-12 hours to account for winter, that means I need 35-42 amp hours. Seems like a fairly substantial battery pack, isnt it? What sort of voltage? Looks like minimum daylight in my area is actually about 9.5 hours. Suppose we could set the sights lower and assume they wont be out looking for it past 2am.
  9. Focusing light

    Honestly, on the scale of this project, if the radius went up to like 200 feet it wouldnt be tragic. Were talking about caches that are several miles apart, and you wont know to look for the light until you read the clue at the previous cache anyway. I dont want you to be able to follow the light all the way to it, and I want to minimize how much it disturbs other park users and wildlife, so I would like it as restricted as is reasonable.
  10. Focusing light

    Ok. The exact radius is negotiable. Kinda why I posted the question, don't know whats practical. : )
  11. Focusing light

    No, I specifically want it to only be visible from one spot. think geocaching, ideally I want you to have to stand in a particular 5-10ft circle (at the previous cache) and the light is your only method of finding the next cache. I think my challenge here is going to be restricting it enough over that distance while still having it bright enough. Like, if I could just put a landscape light in the dirt at the right location, I think that might be visible across the valley, but if you're seeing through a half inch tube, most of that light is blocked. Im assuming I need to direct more of the light down the tube than a half inch circle would normally get without my help. And long time is right, Phi. I dropped in a while ago for one post, but I think even that was years ago.
  12. Focusing light

    Defining visibility: The idea is for it to be visible at night. The location is in the hills about 5 or 6 miles from the nearest town. That being said, its about 5 or 6 miles from several towns, sort of nestled in the dead space between them. The goal is certainly not to illuminate any surface from 2 miles away, more like make it look like there's an unusually low star in the middle of one of the hills across the valley. I was reading that the human eye can detect candle light from something like a couple of miles, but I think that was more of a theoretical limitation than a practical one. If it could appear a little brighter than any actual star that would be cool, but I wouldn't want anything more than that.
  13. Focusing light

    I want to make something like a solar powered landscape light visible from several (2 to 5?) miles away, but only from one location. The one location part seems relatively easy, I can just put it in a box and make the opening a long tube, pointed at the location. I am less sure about it being visible from that far away. To make it easier to spot, I was wondering if it is possible/practical to direct more of the light down the tube to increase the intensity. My first thought was to coat the inside of the box (sphere?) with something reflective, so light from the source bounces around until it eventually goes out the right way, rather than just being absorbed. next I was wondering about properly shaped lenses and reflectors. Like if i were to put a parabolic reflector on the side opposite the opening, am I gaining anything significant? Would a dome shaped lens at the opening refract enough down the tube to make a difference? If you can't tell, I don't have much experience with optics. Not sure what the best reward/effort option might be. Generally restricted to the low tech/DIY options, though not against spending $50 bucks or so on a lens if it would make a difference.
  14. building small transmitter and reciever

    Well sweet hot damn son. So the gun in question is pneumatic, with a piston valve. Our favored projectile is a concrete plug made by using cuts of pipe the same size as the barrel as a form. I just said potato core because didn't put much thought into the sentence, not thinking that was the pertinent info. As I said, I don't have an accurate measurement, I was going by the fact that the rancher told us the fence we were firing toward was 700 yards away and we were getting a good deal past it.
  15. building small transmitter and reciever

    1. What I described is the full project I have in mind. I do really want to build it myself, that's at least half the fun for me. 2. I admit I don't have any sort of accurate measurement system, it's purely estimate. But why do you say that?
