When you think of magnets you probably imagine being a kid in class playing with them for the first time, figuring out that forces we can’t see have the ability to manipulate physical objects.
We can make things affected by the magnetic waves, but not until recently have we been able to “program” them.
A highly innovative company from Alabama have introduced to the world “Polymagnets,” and they’re incredible. They’re guaranteed to be one of the coolest things you see today!
What does dream interpretation have to do with objective cosmology?
Nobody is saying “we right now have the final answer of the most fundamental truths of the Universe.” Nobody contends we have the Grand Unified Theory figured out.
What we DO know is that we DO have a pretty darned good grasp of a lot of basic physics, with no objective reason to believe we aren’t correct to a lot of orders of magnitude of precision. God gave us brains, and if you apply it to what you see in the sky at night, and what you dig up in the dirt under your feet, you can pretty easily come to very reasonable conclusions about what you perceive, you can use those conclusions to predict things and perform experiments and see results which confirm those conclusions were correct.
The notion that we _can’t_ know _anything_ is a tenent of Islam, and see where that gets them.
The notion that we _can_ know things is a tenant of Western Christianity, which has greatly improved our lives.
It’s not “arrogance” to perform the scientific method, learn things about the universe, and fairly conclude that you do, in fact, have a clue about creation. What IS arrogant is to claim a perfect understanding of how Scripture applies to all things, and to dismiss science without having a d@mn clue about it yourself.
Wanna try again?
You could have a mechanical key inside an aluminum (or wooden or whatever) door that is not visibly obvious as a lock.
Lots of tricky stuff.
I start with the axiom that the Bible is true, not a deception, but that we do not yet know how it is all true, how some of the paradoxical passages are not actually paradoxical. There are some deep Physics lesson int he Bible, if you have some good foundational knowledge of Physics ... like the conversation Jesus had with Philip in John 14. What Jesus told Philip in such succinct wording required that Jesus understand the concept of dimensional reality way beyond what was known in that day.
I can thi9nk of an immediate value with hidden chambers, like behind a set of bookselves, with no key or lock visible tot he outside of the passageway.
Just because we don’t always know how to reconcile Scripture with physics doesn’t mean the latter is automatically & completely wrong. Too many seem to think a two-page summary of cosmology as explained to a goat herder is supposed to totally disqualify millennia of scientific inquiry. I don’t see any conflicts, given the appropriate perspectives of each.
Well done. Succinctly, Energy cannot be created or destroyed.
Ah, briefly confused it with the adjacent sections on dreams. The fact that those witnessing the “hand” were drunk does likewise obfuscate what happened.
So...either miracles do happen (I don’t have a problem with that), or the summary of the incident glosses over the “how”. I’m not going to discard the whole of science just because of a highly localized supernatural incident lasting no more than minutes and perceived by a bunch of drunks.
One of the characters in my current novel tells his seventeen years old audience that God does miracles; Angels use technology ... and there are good Angels and bad Angels.
As a software engineer, I’m increasingly likening myself to a wizard: sit in small chambers with mysterious artifacts, designing & chanting/gesturing incantations which bring inanimate objects to life and reveal great & obscure secrets.
I only took one course in electromagnetism, but here is my two cents. This will make electrical motors much more efficient, and cheaper to make. By making the magnetic field tighter you also reduce radio interference. Batteries that run little motors will also last longer. In fact with this technology motors will be made in completely new shapes. I could also see how you could make motors that follow a path, guided by a printed magnet on the floor. This technology might be a solution the many of the problems that plague driverless cars. The applications are endless.

This technology is neat, and useful and interesting. Yes.
Please elaborate how this technology will make motors much more efficient, and cheaper to make. If you need to quote the posted article, just skip the reply.
Only if the patent clerk is incredibly lazy, or very stupid.

Or super hot, not bloody likely...
Thanks Red Badger.
Thank you for the great link.
I should have made it more clear that I agreed with you that they are generally not used for larger motors. This is why I mentioned the 50hp 3 phase induction motor used on our resaw. And then mentioned that the application that a permanent magnet motor would be considered for would be the variable speed feed motor.
My only disagreement was with your statement that they had very limited applications. In CNC and robotic machinery which is a growing segment of industry their use has been expanding greatly.
Ping.
Wonder how small they can print these? Thinking of tiny magnetic gears and such. You could build a watch with them.
I am slowly coming to the conclusion that an alien race is giving us technology. No way we advance this quickly.
