Fact or Fiction?: NASA Spent Millions to Develop a Pen that Would Write in Space, whereas the Soviet Cosmonauts Used a Pencil
Saturday, December 30, 2006
This is my reply to the previous post(this article), it became rather long so that’s why I made a new post. You sure don’t have to read it, I foremost wrote this for myself.
I do agree with the text that textbooks should be clearer in explaining the philosophy of science. There is no such thing as absolute facts within science. This also is the only thing I agree with….
"If the theory of gravity were true, it would show that the sun's gravitational force on the moon is much stronger than the earth's gravitational force on the moon, so the moon would go around the sun." I recalculated that and the gravitational force between the sun and the moon is indeed twice as large as the gravitational force between the earth and the moon, but this does not mean that the theory of gravity is not "true".
The moon does(read: can be explained according to the simple theory of
I actually made a model of the solar system in Java for our project with only the simple laws of
“Because if the moon's “gravity” were responsible for a bulge underneath it, then how can anyone explain a high tide on the opposite side of the earth at the same time?” That sure is a good question, but it also has an answer and it can be explained using Newtons Theory. From wiki: “On the opposite side of the Earth, facing away from the Moon (the antipodal point), the water is farther from the moon than the solid earth, so it is pulled less and effectively moves away from Earth (i.e. the Earth moves more toward the Moon than the water does), rising as well.”
“astronomers, who seem to have a fetish for gravity, tell us that the moon rotates on its axis but at the same time it always presents the same face to the earth. This is patently absurd.”
LOL, come on! This is perfectly possible within
“This cannot be resolved by pointing to the huge outpouring of energy from the sun. In fact, it is known that the flux of photons from the sun and the “solar wind” actually tends to push earth away.”
True, photons do exert a force on earth, but
“so he invented a whole new branch of mathematics, called fluxions, just to “prove” his theory. This became calculus, a deeply flawed branch having to do with so-called “infinitesimals” which have never been observed.” Hahaha, “just to prove” lol. That’s a decent reason to invent a new branch of mathematics if you ask me. The application of Calculus is so easy to observe. Distance, velocity and acceleration are beautifully defined by Calculus. Calculus is relatively simple and so beautiful in its ability to model reality as we observe it. There is no such thing as a mechanical engineer without Calculus and I don’t think I have to explain why we need engineers ;)
“And even children can see how ridiculous it is to imagine that people in
“Adherents have a hard time explaining, for instance, why airplanes do not fall.”
I can do that, like most people who have an interest in physics. If I remember correct, Bernoullis theory that more or less explains this, can be directly derived from
“The theory of gravity violates common sense in many ways.” Science have shown us that the world isn’t as common as we might think. It’s a freaky weird thing that can’t be explained using common sense. “It violates common sense” is definitely no argument.
“It is not even clear why we need a theory of gravity -- there is not a single mention in the Bible, and the patriotic founding fathers never referred to it.” Why do we need it? First of all because we are curious about the world around us and we try to model that world to get a better understanding of how things might work. Second, it's this curiousity that has brought us TV, computers, Internet, cars, planes, etc,etc... Go fuck that Bible please! Thank you! Gravity is a weird thing and it is true that Newton had a hard time defining gravity, but his model is pretty neat. The arguments in this article don't focus on real problems with the Theory of Gravity.
All physics textbooks should include this warning label:
“This textbook contains material on Gravity. Universal Gravity is a theory, not a fact, regarding the natural law of attraction. This material should be approached with an open mind, studied carefully, and critically considered.”
The Universal Theory of Gravity is often taught in schools as a “fact,” when in fact it is not even a good theory.An interesting and strange approach on the Universal theory of Gravity.
Pretty disgusting. It almost looks like one of the videos the terrorists always make when they behead someone.
But is it the real Saddam?

A Japanese man has survived for 24 days in cold weather and without food and water by falling into a state of "hibernation", his doctor has said.complete article... This is amazing. Maybe they can learn something from him. I wouldn't mind to hibernate for a couple of decades when I'm near death's door.
He had almost no pulse, his organs had been shut down and his body temperature dropped to 22C (71F) when he was found.Medics say they are still puzzled how he survived because his metabolism was apparently almost at standstill.
MIT OpenCourseWare (MIT OCW) is an initiative of the Massachusetts Institute of Technology (MIT) to put all of the educational materials from MIT's undergraduate- and graduate-level courses online, free and openly available to anyone, anywhere, by the year 2007. MIT OpenCourseWare can be considered a large-scale, web-based publication of MIT course materials. The project was announced in 2001. As of August 2005, 1435 courses are available online. While a few of these are limited to chronological reading lists and discussion topics, a majority provide homework problems and exams (often with solutions) and lecture notes. Some courses also include interactive web demonstrations in Java or Matlab, complete textbooks written by MIT professors, and even streaming video lectures.What a great initiative. Definitely something to check out, although at this moment my own studies take up more than enough of my time. Their Earth, Atmospheric, and Planetary Sciences section looks pretty good though.

Een van zjin functies van een gebouw was dat het licht moest opvangen en bewaren volgens Corbusier. Deze kerk word altijd als voorbeeld genoemd van de kunst om licht optevangen.
In mijn opinie is was Corbusier een man met een vernieuwend idee maar met de uitvoerings kwaliteiten van een kleuter. Al om al een typische fransman.

Details of deaths of Jews and other groups in concentration camps were well publicised.
The mass of ordinary Germans did know about the evolving terror of Hitler's Holocaust, according to a new research study. They knew concentration camps were full of Jewish people who were stigmatised as sub-human and race-defilers. They knew that these, like other groups and minorities, were being killed out of hand.
They knew that Adolf Hitler had repeatedly forecast the extermination of every Jew on German soil. They knew these details because they had read about them. They knew because the camps and the measures which led up to them had been prominently and proudly reported step by step in thousands of officially-inspired German media articles and posters according to the study, which is due to be published simultaneously in Britain and the US early next month and which was described as ground-breaking by Oxford University Press yesterday and already hailed by other historians.
