Gauss

AI Thread Summary

Gauss utilized the least squares method to calculate the orbit of Ceres, refining observational data to achieve accurate results. This approach involves minimizing the sum of the squares of the differences between observed and predicted values, allowing for a reliable estimation of an object's trajectory. By assuming an elliptical orbit and incorporating various measurements, Gauss could effectively determine the asteroid's path. The discussion highlights the mathematical principles behind this method and its significance in celestial mechanics. Understanding these concepts is crucial for accurately predicting the trajectories of celestial bodies.

I've been reading 'Measuring the World' by D. Kehlmann, i have reached to the part when Gauss using the least square approach (¿? still not 100% sure) discovered the orbit of 'Ceres' but my question is How did he get it??.. assuming the orbit is elliptic and using some possible meditions how could you get the trajectorie of an asteroid or something similar?, thanx.

Very elegantly.

Thread 'Light speedup question'

If light travels in a wave, couldn't we "speed it up" by making it travel in a straight line?

Thread 'Question about pressure of a liquid'

I am looking at pressure in liquids and I am testing my idea. The vertical tube is 100m, the contraption is filled with water. The vertical tube is very thin(maybe 1mm^2 cross section). The area of the base is ~100m^2. Will he top half be launched in the air if suddenly it cracked?- assuming its light enough. I want to test my idea that if I had a thin long ruber tube that I lifted up, then the pressure at "red lines" will be high and that the $force = pressure * area$ would be massive...

Thread 'Why is the 3 body problem unsolvable? And what will happen if someone solves it?'

I feel it should be solvable we just need to find a perfect pattern, and there will be a general pattern since the forces acting are based on a single function, so..... you can't actually say it is unsolvable right? Cause imaging 3 bodies actually existed somwhere in this universe then nature isn't gonna wait till we predict it! And yea I have checked in many places that tiny changes cause large changes so it becomes chaos........ but still I just can't accept that it is impossible to solve...
