Then I'm going to give this a crack and build one. Then I'll check out this space time thing.

send me the Cliffs notes :lol:


+1 Send them to me too. :lol:

I'm going to use this to go back in time to tell my past self its not worth reading the 86 page manual which came with the welder I just bought. Actually wait a minute, if I don't read it, I won't need to build a time machine and then I won't end up going back to ... f$#ken causal paradoxes

Better send the notes first eh :P

Since the coating on a SMAW rod has insulating properties, I'm pretty sure I can build a "flux capacitor" with it. I doubt it will operate in the gigawatt range, unless it becomes slag, which defeats the purpose.

Closest I've come to travelling back in time was when I made instant coffee in the microwave...

Most people see Einstein through a mythology. He was not a super-genius like the characters on "The Big Bang Theory" or "Scorpion". There are similar I.Q.s to his here on this forum. I think he was in the 140's, which is still considered "genius" on that bell curve.

His talent was in seeing the numbers when he'd do thought experiments. I don't see the numbers when I think through issues like General or Special Relativity. They are secondary to me. I see the visual representations in my mind of what I perceive to be happening, then compare them to the provable and/or accepted facts, and adjust accordingly.

I have no way to express, mathematically, the theory I put up. Math is something I am good at in a technical sense, meaning I can make it work for me solving problems I can put my hands on. Math is not something I can use in an abstract sense, to explain an idea.

... and I could be completely wrong. I've just never seen physics explored from this angle, which I find odd since it seems obvious to me that one should not simply assume the nature of something so intangible as space-time.

I've had many discussions with myself over the years (don't laugh) re thought experiments. I think millions of people have since the dawn of time. Unfortunately as much as I love solving puzzles you end up trying to look for pointers in academic literature and it you're right, its all reduced to some kind of abstract math. Now, the problem as I see it is not the math, far smarter people than I understand it and assure me its correct but rather that there are so many unknowns that can't be measured or quantified. I was home schooled and never did a lot of repetitive study. My father used to quote Einstein re why should I memorize something that I can read in a book. A lot of my learning was problem solving and thought experiments. I used to puzzle at the light speed limit for objects with mass. How is it possible there is a speed limit and how it can be quantified to a very specific number. Annoyed me for years that did every time I thought about it. How can an object just increase its mass as it goes faster, and how can speed even be measured or quantified in a space thats moving apart faster than light. Then somewhere I read that special relativity and relativistic mass etc pertains more to local laws so far as the other side of the universe can do whatever it likes. Long story short, it all kinda got stuck when I tried to conceptualize gravity and its influence in my head. That seemed to be the major sticking point for the whole thing, what the hell is it, why is it there, is it just a byproduct of something else we can't perceive/detect/measure etc What if the view-able universe is just the tip of the iceberg and we have no concept or perception of the other 90%

Anyway, I always figured you conceptualize a problem in your head to develop a theory, then try and apply tests to it to prove or disprove. I always liked that idea till I realized that in order to test it you need to apply some kind of alien abstract mathematics to it and thought of where to even start something like that with so many unknown/immeasurable variables just did my head in. No wonder religion got so popular.

Wow - this has to be the strangest " off topic " yet ! clearly there are some great minds here being used at less than their true potential in their current jobs - not sure if the academic community is ready to be challenged by alternate theories of space / time / gravity yet - they tend to have a set mind once one theory becomes accepted - even if you can prove something new they stick to the accepted version of things - maybe if welding becomes too mundane it would worth applying to the " Star Gate " program ? !

Don't look at me... I only just figured out what Otto Nobedder means :shock:

I conceptualize a problem in my head, pour plenty of beer on it. Problem goes away.
