On Dec 29th 1972 a paper was submitted to the American Association for the advancement of Science. The author, Edward Lorenz was an MIT professor of meteorology and the subject of the paper was:- Predictability; [more…]
Introduction As a child I loved playing about with magnets – I still do. They can move heavy objects – such as lifting cars at a scrap yard. They can also move light (-weight!) objects [more…]
Introduction In part one we looked at how a gyroscope seems to defy gravity. This is accomplished by angular momentum. We’ll come back to that later 🙂 In part two we looked at how a [more…]
Introduction The “flat earth” people like to disseminate their woeful ideas. Therefore, let us spend some little time to think about the earth that we all live upon. In particular its spherical (well, almost) shape [more…]
Introduction I woke up one morning thinking, “I’ll write a few articles for GP about the gyroscope. How hard can that be?”. Hmm… Well it turns out that that was a really stupid idea. Are [more…]
In previous parts we have covered the basics of Newtonian mechanics, there is a lot more here but the basics provide enough to at least start to use this sort of stuff. So lets have [more…]
In the last part we covered a little bit about the earth and the moon, we have established there should be a common centre of rotation as both rotate around this common centre. If our [more…]
If you pick something up and lift it, this takes effort, if you let go it will fall, but why? We know objects, such as leopards, have a mass (m) as a fundamental property, we [more…]
In part four we covered the basic principles of constant rotational acceleration, moment of inertia and related topics, in this part we will take this and demonstrate what this means. When we looked at constant [more…]
