Mathematical Challenge !

[Brigade77]

You chuck 5x shovels of 20mm ballast in a Belle 150 mixer several times a day, almost every day of your life.

The next time you do this, before you shovel the cement or bucket the water in, please let the ballast revolve for at least 5mins.

You have seen this, yet you choose to ignore it, the 20mm ballast is revolving around the tub & you might happen to notice that the biggest of the 20mm pebbles are all congregated inb a certain area within that tub.

Do you understand what is happening here ?

No you don't. Because what is happening here is the mathematical equivalent of order within chaos. This is quantum physics in its most simplest form.

If you fully understand what is happening here then you have just cracked the weather prediction problem & invented the abilty to predict the next time a self driving vehicle will have an accident.

Do you understand what is happening here?

I don't think that you do.

This is quantum physics at its most simplest form yet it solves one of the most basic of problems. There is order within chaos.

If the bigger lumps end up on top (which is top in a revolving drum?) is it not just that the smaller lumps can fall through the spaces between the bigger lumps easier than the bigger lumps can fall through the spaces between the smaller lumps?

 

[Doggit]

It's the other way round. The smaller pieces settle in to their own spaces next to each other, and so fit together to make a layer that the larger pieces roll over. But I don't think it's quite order within chaos, more a case of natural physics. Quantum physics on the other hand (as my very limited understanding of it goes) is more to the level of quarks whereby two people looking at the same object will see it doing different things, and that those two objects can communicate over great distances independently of anything we understand. It will be the stuff of intergalactic travel, and instant communication over light years, and it also has the possibility of teleportation.

There are too many unknowns in your theory to assess the reaction in the mixer. For example "5 x shovels" is not a specific amount and the tiny difference that a loaded shovel (for example) against a non fully loaded shovel would have on the ratio of large stones / small stones would introduce a non-linear aspect to the mathematical equation thus the outcome would always be variable. Such is the concept of non linear Chaos versus linear Chaos. Weather prediction is also non-linear Chaos.

 

[Doggit]

Sorry conny, variable amounts don't come in to this type of question, because 3, 5 1, or 9 shovels, with unknown ratios of different sized gravel also doesn't make any difference either. imagine a set of blocks with say 10 being 1x1, and 5 being 2x2, all being on a vibrating plate. The 1s would all vibrate together, because they are a uniform size, whilst the 2s would roll across the top of them. In a similar manner, the larger stones rise to the top because the they are larger, and will therefore roll over the top of the smaller ones.

And whilst I have no idea how to respond to a the concept of a linear verses a non linear chaos theory, I suspect there is an undiscovered pattern to weather prediction that will one day resolve what we currently perceive to the random chaos. It will just require enough weather sensors, and a better understanding of how things interact.

Chaos is just a term for saying we don't understand the situation, so in some ways, Dorks right when he says that one days we'll be able to predict when a driverless car will crash.

yes but if you allow the mixer to run for 1 year, you won't get any 20mm pieces left in that, they would all crumble to less than 1 mm pieces, and it will be a total chaos!

so out goes your mathematical equation, it is time dependent!

yes but if you allow the mixer to run for 1 year,

You will drive your neighbours nuts!!!

I'm not 100% sure of your methodology but you just might be onto something . I'd hazard a guess but I don't think he used a cement mixer and a lorry load of gravel but he did use mathematics for predictions,
http://www.news.com.au/technology/s...s/news-story/6de2e69055a4e7b9f465edff1e550583 Sounds a bit sci-fyish with shades of Hari Sheldon's physcohistory but perhaps between his calculator and your shovel you could solve the world's problems before they get any more serious.

What I need is an explanation of why an egg cannot be un-beaten simply by reversing the rotation of the beater until the egg is reformed.

 

[ladylola]

Well superman wizzed round the earth and put things back the way they were , perhaps you just need to beat quicker.

This is the ultimate proof that time cannot go back, so it is a bit of a bad news for all those time travelers. Which is somewhat a good news, Universe will remain expanding and will never go back to singularity. Unless someone was standing up there somewhere with a gigantic cosmic fishnet and scoop all planets and stars in this net and throw them all in a black hole and then of course we would all shrink into a singularity point.

Sorry Mike; this is just interesting ideas taken to absurdity. The sun will die out in 5million years, but we'll be long gone, so some time dependant arguments are just that, arguments. Common sense would tell you to buy 1mm gravel, and the mixer wouldn't survive running full time for a year either. And if you deliberately left it going that long, then you would be achieving your aim of getting 1mm pieces, so no chaos there.

For any theory to be feasible, it has to be reasonable. And chaos theory just says we don't have all the information to hand yet.

And just because the universe is expanding, it doesn't preclude the ability for and individual to go back in time, because whilst the planet would no longer be in the position it occupied on a previous occasion, it can be reasoned that if you had the ability to go back in time, you would also have the ability to arrive at the exact point you wished to, as opposed to effectively arriving in the space that it occupied at that previous point in time.

 

[EFLImpudence]

5 billion years. No need to panic.

 

[Doggit]

Phew, thanks for that EFL. But if hollywoods to be believed, I'm sure they'll just wait till night time, and drag a new one into place.

We know that time travel will never happen because even if they have strict rules on not revealing you are a time traveller, one day in the infinite future some arsehole will go all the way back into the past & reveal that time travelling exists.

They didn't, so it doesn't & never will.
