Anyone for Chess?

[Tarsier79]

Gday

I like to dabble in chess, and have found two great free sites. http://gameknot.com and http://www.redhotpawn.com
limited to 6 games each for non-subscribers like myself.

Note: There are adds on both sites, but I have not had any pop-ups.

Unfortunately my genius does not extend to chess, but I enjoy it all the same.

Have fun!!!

Life is too short for chess, crosswords [all types] & sudoku ;7)

Once you know the pattern & the system they become trivial - what really annoys me about crosswords is that you have to get inside the authors head to understand him & how he writes his clues to understand them - I have enough trouble understanding myself without wanting to dive into anybody else's murky waters ;7)

All in jest - I do an occasional sudoku from time to time then loose interest when I have to guess at a couple of options & it turns out wrong - must have no patience, lol.

[Tarsier79]

It does have its patterns, but its the problem solving I like.....How did I get myself into this mess, and how am I going to get out of it?

That is also why I like attempting to solve the Bessler wheel puzzle.

[Fletcher]

Pattern recognition - any computer can do it.

[Tarsier79]

Its a pity a computer can't solve the wheel!

[Fletcher]

It could if you fed in the right inputs, parameters & assumptions - it is a logic processor but if the information & model is faulty then there can be no logical output & that is why most of us cannot solve the problem.

[Tarsier79]

That is the problem. There are infinite parameters, and our assumptions may not be correct. We may need to stumble upon a solution rather than create one.

[Fletcher]

There are not infinite parameters - they are contained in the field of known physics [which was a smaller field in Bessler's time] - there is no doubt that most who pursue this quest make wrong assumptions else an answer would be in our hands now, & if somebody had worked it out before & for whatever reason it got shelved, then someone else would have also arrived at the same place by the same logic - but that is not the case.

Whilst it is entirely possible that someone might 'stumble' upon the correct solution if they leave the main paths traveled I think it more likely that a solution will be 'created' from hard work, & thoughtful experimentation.

I like what you say Fletcher.

We are following a path of assumptions. There must be a point in that path we need to deviate before the next step.

Perhaps we need to list all our assumptions and decide which ones are possibly wrong.

Yet the most likelihood is an assumption that occurs at some point in a design or build. A point in the sequence we won't think of unless it relates to a specific design.

So you you need to know which "horse and cart" style you are going to build before you can find that deviation point.

[Fletcher]

Assumptions :

1. For every action there is an equal & opposite reaction.

2. Energy cannot be created nor destroyed, just change form [law of thermodynamics]

3. Gravity is conservative.

4. Engines that can do external work at a set rpm are in equilibrium i.e. Joules input = Joules output [ordinary friction losses & work done externally]

5. If work can be outputted in the form of Joules then the system must have an input of Joules.

6. Joules entering the system must be sequestered from an immediate environmental source, which in turn is depleted by the same number of Joules, until the work done in Joules is changed into the raising of potential & heat etc by mechanical action N.B. net wider system energy remains constant.

Conclusion :

1. If no visible source of fuel [chemical energy] enters the system to provide Joules then an invisible source of fuel is entering the system.

2. If the engine is not consuming fuel to form chemical energy which in turn creates mechanical energy, then the source of Joules is coming from an environmental gradient or differential that the engines form & geometry exploits, once rotating.

3. The speculated differential or gradient is most likely temperature dependent causing a localized heat sump or sink allowing heat to flow from hot to cold adhering to the laws of thermodynamics.

Comment :

1. How many can get past point 2 before deviating ?

P.S. I just advanced some of my chess pieces - your move ;7)

[Tarsier79]

This game isn't looking good for me. The benefit of playing someone who is a better chess player, is that even if you lose, you have to take something from the game in order for your game to improve.

There have been many inventions that have been discovered by "stumbling" over them. Eg. Laminated Glass was discovered when a chemist knocked his beaker (that had not been cleaned) off a table and it didn't smash.

I agree, you are not going to happen across a working wheel without a correct amount of preparation, understanding and hard work.

Maybe I'm lacking in the understanding department :o}

Speaking of lack of understanding, I understand momentum is conservative (unless pequaide gets his way), but how is gravity conservative?

[Fletcher]

Gravity causes an acceleration in any object with mass - the acceleration is constant [for all intensive purposes] - think of it this way - every atom has the same acceleration acting on it so a large group of atoms accelerate at the same rate as a smaller group of atoms, in a vacuum.

When an object swings down & around a pivot gravity accelerates it - btw, its velocity is the same at any vertical height as the same object falling vertically in free fall [at the same vertical height] - the object accelerates & gains momentum & Ke - after swinging by 6 o'cl momentum carries it upwards [less losses] - on the upswing gravity is still accelerating the object [the same number of atoms] exactly like it did on the way down, so it robs the object of momentum & Ke - the force is equal on both sides of the pivot, zero sum, null game [not counting frictional losses].

N.B. that's why it does not matter what path an object travels as it falls from a height to a lower height, or up again i.e. acceleration due to gravity can not give more than it takes back aka a conservative force takes what it gives [no exceptions], it conserves !

[Fletcher]

Yes, there are examples of happy coincidence which would appear to be stumbling onto something important - the microwave is the usually cited example - no one would dispute that myopic discoveries occur all the time in science - my point is that no one has 'stumbled' on a working solution to Bessler's wheel which I refer to as an engine, not from lack of trying or imagination, so it must be understanding IMO.

My personal opinion is that it is not an anomaly of physics, which I sincerely doubt because it hasn't been found, but an exothermic engine just like any other that converts energy to mechanical work & that means a fuel source or gradient created & I don't believe a must be replenished fuel source was added.

Thanks Fletcher, your comments are always appreciated.
