Why are the formulas not published?
The trajectory of ball bouncing from wall is indeed computed routinely with various numerical methods and nothing very strange is about it
why we should pay such intellectual exercises from our taxes
like the cold fusion or antigravity drives are ignored for years
Many Indians believe in reincarnation. Perhaps Sir Isaac Newton has come back in the form of 16 year old to accomplish unfinished business?-You mean like pirouette/Ritchieguy keeps coming back to deposit new inanities like no one would notice? From another thread:
Yes, gold can be cast with lost wax method.Nobody said anything about lost wax method. That was ritchies idea and you wouldn't have known that unless you are him.
This example just points to the uselessness of these formal derivations: the particle simulation can handle much more complex situation effortlessly, whereas the analytical solution is useless in most of practical applications. Now the question arises, why we should pay such intellectual exercises from our taxes? We should adopt similar model here, like for financing of art or various sport or personal records collected in Guinness book. Whereas the really useful findings, like the cold fusion or antigravity drives are ignored for years. The mainstream physics proved its separation from reality again.
What he did here was not numerical simulation. It was to give an exact solution (including air resistance)..This is just what I'm talking about. It's mathematically exact solution of certain situation, but useless from practical perspective anyway. This solution still neglects many aspects of real situation, like the rotation of ball, dissipation of energy and variable elasticity of ball under impact - which will affect the actual path of ball even more, than the air resistance. It's waste of money and effort from this perspective.
Have you never heard of great scientific innovations derived from curiosity-driven science? Electromagnetism, penicillin, etc.Well, exactly - these finding had nothing to do with derivation of math. BTW The greatest innovation of all time is still cold fusion.
would ramp up funding for science as the payback tends to be handsomeJust the pumping of money into useless formal physics like the string theory has caused the ignorance of practical findings, like the cold fusion. The physicists has learned, their money are going even when they find anything useless, the piling of theories is enough. Why to support just the approach, which deepens such an ignorance even more? You completely missed my point, as the era of formal physics is over - what we need is the curiosity driven science again. Not the jobs, salaries and research grant driven science which is full of ignorance, as we are facing today.

Hey russkiyRitchieYes, gold can be cast with lost wax method.Nobody said anything about lost wax method. That was ritchies idea and you wouldn't have known that unless you are him.
You've outed yourself yet again you stupidass.
Terriva; you're insane, you sound like you're not, but you areWell, if I'm insane, then Andrea Rossi with his cold fusion is fraud and nobody will ask, what the mainstream physics did during last twenty years, when fought against cold fusion research. But if Andrea Rossi will introduce the E-Cat into market, then the layman people will suddenly realize, they're feeding the physicists like parasitic alchemists of modern era and they will ask their money back. IMO this controversy will be resolved soon.
LHC was what, ~$10B'ish? Next to the iraq war that's a drop in the bucketThe reason of Iraq war was the increasing price of oil, which would never happen, if we would research the cold fusion responsibly. Now this war initiated the financial crisis in the same way, like the lost war in the Vietnam. We all are paying for ignorance of physicists by now.
No, I think it is far more than statements made by Richie that were inane. I think that GhostofRetardo has big fascination and obsession with this Richie and possibly love-hate thoughts in his head.Funny... ritchie used to say this very same sort of thing... ritchie.
My roommate who is psychologist believes that to be true.And what does your learned roommate have to say about pathological liars? And people who insist they see glass-headed martians in NASA pictures even after it is explained to them that those martians would have to be 1000 ft tall and lying down because ritchie did not understand camera angles? Or about how black holes do not attract other black holes with any more intensity than objects of similar mass just because they are also black holes?

A good definition if insanity is repetitive and increasingly grandiose denials of what is obviously true. You're a much bigger moron than what passes for a 'normal' reality denier on this site.
How about you say something genuinely insightful? No one is stopping you from doing that.
Lol, give a tard enough rope, he'll hang himself.- CardacianNeverid/FrankHerbert/bewertow -
I will contact the Federal Bureau of Investigation and also the State Department to inform them of your harassment of a foreign guest from Russia.Here let me help:
Boy does THAT have a lot to do with math, ghost.War is all about numbers. Plus for you, minus for your enemies.
Solving a 350-year-old open problem is good for second place? What came in first??
If it had taken place in India, I would have been very skeptical
The people who invented Hindu-Arabic numerals all died a long long time ago. Get over it.If it had taken place in India, I would have been very skeptical
WTF? You would have been skeptical if it took place in the country that invented the very numerals that are being calculated?!!! You need to open a history book.
.. they allow you to test your numerical solutions against a known clean sample of data to determine how good your algorithm is, at arbitrary precision...The common numerical methods handle this problem automatically in every step of calculations.
An exact solution is better than all the world of empirical data full of noise.Better for what? It's mathematically exact solution of certain situation, but useless from practical perspective anyway. This solution still neglects many aspects of real situation, like the rotation of ball, dissipation of energy and variable elasticity of ball under impact - which will affect the actual path of ball even more, than the air resistance.

Ghost of Blotto should crawl back to the intellectual sewer where he was incubated. This abjectly base creature is continually compensating for an inferiority complex and pasting his pathetic ego over privileged space where he has nothing to contribute except the doubtful continuance of his conflated genetics.Arkaleus is that you? You forgot the word 'concupiscence'. Please try to include it in your next deposit.
For example, most common numerical methods converge to the mathematically exact solution in the easily predictable way
if you need the physically exact modeling of the real situation, use the numerical methods - not the analytical solution.
Even if you don't exactly know, how numerical method converge, the running it at smaller step will reveal easily, if it converged to the exact solution or not.
No idiot they had children and their genes now reside in the population of India. This might be a reason why Indians earn the highest income per capita among all the races in America.
For every intelligent American, you have four in India, who are more than happy to emigrate to where the money is.
it can very well converge to a local minimum in search space that is not the exact solution) ... Maybe it converges to a different solution that merely appears correct?This is very rare case for the simple model examples, which are solvable analytically. Actually, most of numerical methods use this method for dynamic adjustment (coarsening) of computational grid and for many other purposes. Usually when you're able to solve the model analytically, then the numerical methods have no problem with iterative solutions, because these models are constrained to quite trivial examples. And I'm not talking about situation, when analytical solution is available in form of implicit functions or recursive series, which must be evaluated with computer anyway.
.. problems can often be decoupled into a set of exactly calculable parts and parts that need to be simulated..This is rather rare case and it usually goes at the price of complexity of simulation and stability of solution.
THIS is a mystery. How can someone make a comment that does not show up on their activity page? I am sure I have seen posts by this dweeb but his activity page shows none of them. Lets try giving him a ranking... nope that didnt work.Ghost of Blotto should crawl back to the intellectual sewer where he was incubated.

You are quite fond of yourself. You must be THE intellectual giant amongst apes.
