1. ## Q - NItorgen and Air expansion in tyres

Nitrogen is not going to erode the tire as high pressure oxygen will (slowly). That is the only reason it is used.
2. ## Comparison of Two Models

My previous thread was closed because i dared to stray from one subject and mention the other. So this thread is specifically created for the purpose of discussing the comparison and contrast between climate models and the models you might use to calculate lotto numbers. Numbers of variables. The lottery model contains 36 identical pingpong balls. A climate model requires hundreds of parameters. https://wattsupwiththat.com/2011/06/30/earths-climate-system-is-ridiculously-complex-with-draft-link-tutorial/ https://wattsupwiththat.com/2012/01/21/the-ridiculousness-continues-climate-complexity-compiled/#comment-872002 Starting positions The initial positions of the 36 balls can be determined very accurately. Less than 0.1mm precision. The hundreds of climate parameters are less easy to measure. Models The ping pong balls can be described by models which require few laws of physics. Newtonian laws of motion, conservation of mass, momentum and angular momentum pretty much covers it. The climate models are harder with the hundreds of variables all interacting in different ways Results We are trying to use the current state of the ensemble to predict the future trajectory of the system. That means that in ten seconds time when we select a ball we want to know which one it will be. In climate we want to know in ten years time the state of the parameters, paticularly temperature. Many people get confused at this stage and start talking about taking averages of thousands of different possble scenarions. A Monte Carlo simulation for example. But that is not what we are trying to do. This problem is about determining the next single trajectory, not the average of all possible trajectories and that is a major difference. Conclusion. Given that we can model the climate very accurately and made loads of useful predictions why has nobody bothered to model the lottery?
3. ## Science, truth, and knowledge

As an independent observer on this thread that does seem to be the standard response when they are in a bit of a fix, Reg. I get the impression that they are just trying to keep batting you away and hope you leave rather than just admit you have a point.
4. ## climate change intensified the amount of rainfall in recent hurricanes

I kNEW computers could model this stuff!
5. ## Predicting lottery numbers.

Well I have been through the video and although I know it is the right channel I am not now 100% sure that it is the correct video. Basically the summary is that they show that the lottery machine of 36 balls is easy to define and the laws whcih govern it are very simple. The initial conditions are easy to determined to a high degree of accuracy and so with a suitable model it should be no probelm. Actually I think I may have reacted to quickly. I apologize. I have spent a couple of days thinking about the point you made and i think it has some merit. The scenario I mentioned used 36 identical balls bouncing around in space with gravity applied and contained in a confined space. The climate consists of hundreds of different variables such as these listed here: https://wattsupwiththat.com/2011/06/30/earths-climate-system-is-ridiculously-complex-with-draft-link-tutorial/ https://wattsupwiththat.com/2012/01/21/the-ridiculousness-continues-climate-complexity-compiled/#comment-872002 These cannot be measured as precisely as the balls, of course so the starting position will not be as well understood. But I see the point you are making. If we can predict the climate so accurately way in advance despite the fact that there are many more variables and they are not as easily measured then surely it must be possible to predict next week lottery numbers. When I find the video I am lookng for you will see that the methodolgy they propose is pretty much as i described it.
6. ## Science, truth, and knowledge

Right so I have tracked down the original quote: On 31/10/2018 at 11:40 AM, Carrock said: Euston station is six stops away from Kings Cross station" That was it. One single line which you most definitely DID write. How do we know? Two reasons. Reason 1. The board provides an automatic mechanism to describe the time the original quote was made. Reason 2. It is still on the board. I just wonder why you crammed FOUR (4) lines in there and claimed INCORRECTLY that I had attributed them to you when it is clear that they were NOT all from you.
7. ## Predicting lottery numbers.

Not sure whether I can post links but I will try.
8. ## Science, truth, and knowledge

Don't do what again? You seem to be the one making up quotes.
9. ## Cause of Atmospheric Pressure

I think that is the key to this problem.
10. ## Science, truth, and knowledge

Two wrongs don't make a right.
11. ## Science, truth, and knowledge

That sort of comment seems a bit unnecessary.
12. ## Solving inexact differential equation

Your best bet would be to get hold of Abramowitz and Stegun and read it cover to cover. That should not take you more than half a day if you are paying attention and do not allow yourself to be distracted. eg Do not play music or have the TV on while you are doing it. It seems odd that I have to say this but the fact is that these days that is exactly what millennials do when they are supposed to be studying. Once you have done that I and are reasonably confident that you grasped it then the above problem will be pretty easy. I hope this helps.
13. ## Science, truth, and knowledge

OK. Well I would contend that there are other ways to observe. Hearing for example. Smell perhaps. Some people dismiss ouija boards but I am preparing a short essay on that subject which I hope to post in the next few days.
14. ## Auto ignite match stick

I have to say that I am not comfortable with the desecration and burning of The Holy Koran. I dare you to post this anywhere with your name to it!

Well said!
