When europeans first started exploring the americas, the ships were not realy suited for transatlantic travel, there was a strong risk of getting lost, we had no measure of longtitude. There was however a promise of a new land with new riches and whoever got there first was going to control it. We know there’s stuff out there in space for us. It’s almost like the vast oceans that the europeans faced. Our capacity to travel through space is very limited, there’s all sorts of things that could happen to us along the way. For a long time, we tested our sea faring technology in coastal waters where getting too far away didn’t mean that all hope was lost. We can see the moon, we can see mars. Our robotic scouts have gone to visit, and reported back to us. We now know what’s there and what isn’t.
On the subject of what isn’t there, what’s with people wanting to have an orbital colony. There isn’t anything there. We’d be bringing everything with us and then it would need to contiously be supplied. It makes about as much sense as the europeans stopping to build a giant mid atlantic island to further their colonization of the americas. The resources to build aren’t present and it’ll just be an outpost in the middle of nowhere that needs to contiously be maintained and is also subject to more hazards than the americas. Building facilities in space has some logic to it, a permant settlement though exposes us to hazards that need to be dealt with indefinately and overall just doesn’t make sense to me. The moon provides some limited temperature regulation and there’s matter there, which can be used to make things to sustain a colony. Mars does an even better job at temperature regulation. We can also dig into these bodies and use them for debris protection. Forget the large bodies, any random small rock will have merits that beats a middle of nowhere colony.
I suppose I’ll conclude by saying, we still haven’t built the large floating mid-atlantic island, but we do have large coastal construction facilities for building large floating structures. There just isn’t anything there motivating people to settle.

Space Colonization For Idiots, By Idiots
2007 March 9Information for RC Aerial Photography
2007 February 15I recently came across something called The Aerial Photography How-To Book, which is marketted as the definitive how-to book on getting started in the RC aerial photography industry. $50 for an 80 page book on “marketing tips, ideas, and quick start hints.” There are a few sample pages on-line for people to preview. The first one is page 12, which seems to be part of the basic introduction. Basically, the entire page can be summarized as, “if you aren’t familiar with photography, learn that shooting in auto mode doesn’t always produce the correct results.” Page 23 is the next one, the header is about the size of the aircraft and can be summed up as saying that larger aircraft have more potential for damage and greater liability. There’s also a brief paragraph at the bottom for selecting electric vs combustion engines. Still fairly introductory material in my view. Page 30 is an entire page on turbine engines and there’s a picture in the middle dividing the page. I’ll disagree with layout a bit here, the picture neatly divides the page into two columns, having lines go from one margin to the other with a break in the middle makes things a little difficult to follow. The information is once again what I would deem to be a very general level. Some camera triggering techniques are discussed on page 39 as well as a brief discussion on the benifits of a video ground link. Unfortunately, nothing is shown in good detail. The last preview page is 50 and it basically says to have a business plan and pick a good name.
Strangely enough, the table of contents isn’t one of the preview pages. That probably says the most about what’s covered in the book.
Thus far, the book has recieved some pretty good reviews. People like it. Personally, I feel that the content is at a fairly introductory level and likely not very useful. I’d love to see what the book says about the design of weak joints to minimize potential damage and repair time, how mounting a camera affects aircraft stability, and vibration damping. The table of contents isn’t available, so whether or not any of those concepts are even covered at all is a mystery unless I feel like wasting my money on it. There’s only really two things going for that book, it’s seems to be the only resource with that specialization and it’s written at a level that anyone can understand.
Mathematics vs Reality
2007 February 6I’ve started going back to observing the Creation Vs Evolution discussion for a while. Mainly, I’ve been reviewing attempts from religious groups to refute evolution. Every once in a while I come across something that I just simply know is wrong being passed off as truth. This particular instance just happens to be the Coriolis effect and it’s influence on the direction that water drains in different hemispheres of the earth. I was told that it showed organization and provided proof that there had to be a god. This is just a popular misconception. Granted, if we crunch the numbers, consistant results will be produced. This is mathematics.
The Coriolis effect is real, we can measure it, we can see it’s influence. I’m not trying to deny the existance of the Coriolis effect. However, anyone who’s studied fluids or spent a lot of time studying the draining of liquids will know that no matter what hemisphere you’re on any given container can drain in either direction. This is reality.
Of course, mathematics is never wong, it’s just that nobody bothers trying to calculate reality, only a simplified version of reality. A real container of water has all sorts of currents flowing in it. If you look closely at the edges of the containers, there’s water going up and down in small waves. The water is not static, it sloshes around. Some vibration remains that never exactly disappates. The earth is also not a completely stationary surface, it shakes and vibrates and moves around. If we were to attempt to calculate actual reality on something like an sink or an olympic sized swimming pool, we’d find that the real world influences, that are usually left out because they’re simply too complex, have much more influence than the influence of the Coriolis effect.
No matter what mathematics says, what happens in reality is, well, real. When the math disagrees, we simply haven’t answered the right question.
