Re: Why do airplanes need wings?

Another method is called 'boundary layer control', which I really know nothing about, other than it is supposed to lower the stall speed of a wing by a certain percentage. However, as it generally uses bleed air from the aircraft engines, it has not proven to be highly reliable, at least, the U.S. ...

Re: Why do airplanes need wings?

There is no theoretical limit to the size of a wing, the only restraint is the amount of power needed to overcome the drag. Some things have been done to 'spoof, the air into behaving like the wing is larger than it actually is. Flaps are one of those techniques, and date back to the 1930's. Prior t...

Re: Why do airplanes need wings?

The earliest aircraft were interested only in flight, not in travel. They used numerous wings to create lift, because the engines provided very little power. No, early aircraft had multiple wings for stiffness: for a given amount of lift, a pair of wings braced against each other is more rigid than...

Re: Why do airplanes need wings?

This topic relates in a way to space exploration. Because our atmosphere is dense enough to allow winged flight, escaping it is very difficult. We must move very fast to reach orbital velocity, but high speed is impossible in our atmosphere. Therefore, we must lift ourselves above most of the atmosp...

Re: How hard is it to transmit to other star systems?

Well, I have heard of something called the 'inverse-square' law, which states something to the effect that the radiation diminishes very rapidly as you travel away from the source. Another problem is only becoming apparent recently, with the advent of fiber optics. Instead of beaming large amounts o...

Re: Planet disassembly

Of all of the planets, Mercury probably is the most likely to be extensively mined. It has the highest density of any body in the solar system, it is very close to the sun, which makes energy easy to obtain, and also allows for solar sail export of the mass that is refined. If we are looking for hea...

Re: Why do airplanes need wings?

Bear with me for a second before throwing out the standard grade school answer. If you consider any heavier than air flying object/vehicle. In the most general sense, it stays aloft by pushing air down. Specifically, it needs to constantly accelerate a That Mass flow of air equal to its weight Some...

Re: 1011: "Baby Names"

For some reason, I would like to see a child named "Sosueme", primarily because I think that it sounds cool, but also because of the legal ramifications.

Re: QWERTY versus Dvorak

I find it really silly that people switch to DVORAK - if you're going to go through the effort of learning a new keyboard layout, why not try and learn the most optimal one, not just a better one ? I have personnaly created a keyboard layout, helped myself with Carpalx [link to http://mkweb.bcgsc.c...

Re: What OS do you use?

My laptop dual-boots Vista and Ubuntu 8.04. Unfortunately I have to keep Vista around as I need Visual Studio for school *grumbles*. My desktop runs Vista, because multiple attempts to install Ubuntu 8.04 have led to unbootable setups due to a bizarre GRUB error (21). So far, every suggestion for f...

Re: QWERTY versus Dvorak

What i would like to see is the Dvorak keyboard introduced at the same time as the Qwerty. Of course, it might be little bit difficult to explain to the brighter students that the Qwerty is the most commonly used keyboard, but the Dvorak is the one that resulted from a scientific study of typing, th...

Re: Colemak versus Dvorak

My point was, "similarity to QWERTY" does not necessarily mean that it wasn't done in a scientific manner; but it's something that might result from one of the desired features being that people who already touch-type on QWERTY can learn it quickly (something that I don't believe Dvorak t...

Re: Colemak versus Dvorak

Perhaps that is why the Dvorak has been modified, so that there is a classic Dvorak and a USA Dvorak. But the changes were minor.

Re: Colemak versus Dvorak

I had never heard of the Colemak layout until today, while doing an Ubuntu install, where I saw it listed among the options for keyboard layout. I finally was able to look at the actual layout at the Colemak site, and compare it with the Dvorak. It does not appear significantly different from the QW...
