Comment Not easier, more useful (Score 1) 212

The concorde was not built primarily for its speed (that was a nice extra), but for fuel economy. Single-stream jet engines are better in terms of fuel economy when they fly faster. The drag rise counters this, but for the concorde they had the drag rise restriced to an acceptable minimum.

The invention of the double-stream jet engines made that need for speed obsolete.

Yes, the concorde existed, but was soon outdated because of the use of newer, better jet engines.

Indeed. That is why I am interested in different schools of thought in mathematics. For example, the ancient Greeks were builders rather than mathematicians, and therefore solved different problems or similar problems in another way. I would not know how to prove Pythagoras' theorem without the Greek school of thought. On the other hand, the Arabic school of thought brought us abstract thinking. It took aerodynamics to add boundary layer theory to computational mathematics.

The most interesting thing can occur when those schools of thought are mixed. Hodographic transformation as used in aerodynamics is very similar to a Burrows-Wheeler transform in computer science, but the application is totally different. Who knows what other differential equations solving techniques could yield better data compression, for example?

And so was bombing Iraq. While I don't agree with the terrorists, I can understand that they return the "favour" that has been done to them (one of the terrorists apparently came from Iraq). I mean, the main difference between "shock and awe" and "terrorism" is "us" and "them". I just don't understand why they do this to France.

Yes, only it is illegal to even discover the backdoors. This is great for security firms. Those firms are off course not notified of the backdoors, but it will be illegal to report those malicious pieces of code. Unless they are programmed by a non-government criminal, in which case it is their job to disclose them. Nice!
