You are wrong on numerous levels. I'm guessing that you forgot that Pi is not a real number, it's an estimation.

Pi is a real number, but it isn't rational. Maybe that's what you were going for here.

You seem to have forgotten what a "Theorem" is as well and hell, you used the word!. Wtf? There are numerous types of "Math" that we simply can not prove true or untrue. We still use them, because to the best of our knowledge things work in a specific way.

You need to look up the meaning of a mathematical theorem: A statement that has been proven on the basis of previously established statements, such as other theorems, and previously accepted statements, such as axioms.

A theorem is a not the same as a scientific theory, even though the words sound similar. You might have intended to talk about axioms, which are a set of given restraints for a particular mathematical system.

Since the above is true, Math "is" science. Your second statement in bold is a fallacy so just plain old wrong. No wonder you posted anonymously.

There are two schools of thought of the question of "Is math a science?"

  1. (1) The mathematical method follows a similar pattern to the scientific method, so it is science (or a least science-like).
  2. (2) Math is the pursuit of interesting descriptions of possiblities. Mathematical 'theories' are interesting or uninteresting, not right or wrong.

I follow the second school and I think most other mathematicians do as well.

This is a lot off-topic, but: 8-track studio recording was the hot thing in the late fifties when the Ampex 5285 and other multi-track studio records came out. Multi-track analog recorders remained very popular until digital multi-track started to replace the old analog units in the mid/late 1990's. Those studio 8-track machines do not have much in common with the continuous loop cassettes we also call 8 tracks. From a technology standpoint, Kodachrome has just as much reason to still be around as the 8-track cassette - none. From a nostalgia standpoint, maybe there's room for both.

Broadcast television is still free, over the air, and have always had commercials (in the case of PBS stations more subtle, but still there). I don't remember anyone promising me that cable would eliminate commercials. Provide better and more reliable picture quality and add choice, yes, but not change the actual programming delivered.

Jetman Attempts Intercontinental Flight 140

from the a-jetwing-and-a-prayer dept.
Last year we ran the story of Yves Rossy and his DIY jetwings. Yves spent $190,000 and countless hours building a set of jet-powered wings which he used to cross the English Channel. Rossy's next goal is to cross the Strait of Gibraltar, from Tangier in Morocco and Tarifa on the southwestern tip of Spain. From the article: "Using a four-cylinder jet pack and carbon fibre wings spanning over 8ft, he will jump out of a plane at 6,500 ft and cruise at 130 mph until he reaches the Spanish coast, when he will parachute to earth." Update 18:57 GMT: mytrip writes: "Yves Rossy took off from Tangiers but five minutes into an expected 15-minute flight he was obliged to ditch into the wind-swept waters."
