Given a strong enough magnet, mounted perhaps elsewhere on the body, could this theoretically work?

Would it be more effective if the magnet were to repel the bullet instead by reversing its polarity?
24 posts and 4 images submitted.
>>
The bullet is moving about 4 million miles per hour when it hits a target 200 yards away.

Even for a small 30 grain bullet, the forces needed to deflect that would fry your brain and prevent you from having a gun yourself.

Plus bullets are lead, which isn't very magnetic.
>>
Bullets travel really fuckin' fast.
Magnets are really fuckin' heavy.
Guns are really fuckin' metal.
>>
If you had an alternating magnetic field that was too incredibly strong to comprehend on our scale, it would be possible. Lead does interact with strong, magnetic fields.

Do planets emit sounds/vibrations/energies that affect our minds? Do suns? Do objects? I guess you could technically say humans are objects and they effect our minds.

Sound doesn't travel trough vacuum but there's definitely invisible light in different spectrums going through us and there might be gravity waves that hit us.

But in terms of conventional noise which we hear, that's based on our atmosphere, and there's no sound like that travelling through the vacuum.

You can "hear" the magnetic field of planets with the right intrument. Nasa's spacecraft Juno did it a month ago. You can find it online.

MUSK SAYS TESLA WILL HAVE FULLY AUTONOMOUS DRIVING BY Q4 2017


During a conference call today, Elon Musk talked about Tesla’s progress in level 4 fully autonomous driving and while he didn’t want to make an announcement on the call, he said that it is coming sooner than people think:

“What we’ve got will blow people’s minds, it blows my mind …it’ll come sooner than people think.”

Musk’s most recent prediction placed the technology being ready in Q4 2017, around the time Model 3 will enter production.

If only they could be profitable by then, too.

This company is turning into a disaster like Theranos. BMW and Chevy have released new generation electric cars that rival his own models. His gigafactory seems like a sham and creating batteries is not enough.

Is it possible to "jump" to another place in space time by bending space itself? What would happen during this trip? Would time theoretically distort?

I will show my theory with what I believe is logic, I will provide evidence of this logic in the form of a stable theory, that the first act of stupid education was the 'crossing of the eyes' [ it can be imagined stylishly ].

The question I faced was, "Is it logical, if we move our eyes and register their movements, we would after some time know subconsciously the entire route; there is a chance the motion may even appear lucid to our eyes.

If this is logic, I know, and do not theorize, that we are lopsided mentally; and we cannot register the 'universal abyss'. Our eyes are crossed in the sense of being pinned to a single side of the, hypothetical. memory of an abyss.

What's there to clarify, now?

Given you understand what I mean by 'memory of abyss', then, let's move on to the depth of the concept.

Now, I'm representing the wordless here, therefore, abstraction is my best friend; multiple abstractions must be used to communicate what is wordless, or above words.

The 'universal abyss', is another concept - representing what we would, as I would put it, 'become attuned with', if we were wordless creatures ( communication and so forth are still factors of wordless life ). However, it's my argument that our 'eyes are crossed ( in all formats )'; that's, like being pinned to a cross, having our eyes crossed, crossed out eyes and whatever else you can think of.

Our focus is pinned to one side of the 'memory of an abyss', by repetitive bodily motion of primarily the tongue, and our understanding of our tongues motion ( we're essentially tongue moreover a person ).

The resolution is that, we cannot focus on the 'universal abyss', because our 'memory of an abyss' is abstracted through the focusing of senses to a side, or 'wave' of many. Further, given we speak words, surely this would abstract our memory of an abyss ( the focusing on a side or wave, is how it is abstracted ).

You're an idiot, 45 degrees is way off. Southern Poland isn't that far from London.

How is a neural network any different from a typical negative feedback control system?

for example:

https://www.youtube.com/watch?v=qv6UVOQ0F44

My intuition is that what google must be using to identify images is fundamentally different from the method this video uses.

Take a binary tree that assigned probabilities to each node based on previous outcomes, I don't don't think it /really/ is displaying pattern recognition, it's just using negative feedback to control the rate of success.

Is this distinction valid? what actually is machine learning?

It's good that someone makes this kind of video!
However, I'm pretty sure the creature expects his explanation to be easier understandable than it is. I couldn't really follow how to read the boxes and lines.

>>8246243
some people are trying to stretch definition, and classify even a simple linear regression as "machine learning"

Taking others not imaginary in equation,

machine learning is great, but when you did error at database design? How can I learn your machine without changing source?

So are you telling me that a photon is a particle but travels within a non-physical "wave" of probability which follows the exact same laws of physics as ripples in a pond and only materializes into existence if in contact with an observer?

Maybe if you listen to "muh dick much dick flipped a brick of muh shit," you may not be smart to begin with. But I doubt music leads to stupidity. Too many examples of smart people actually being musicians or enjoying music.

I don't see why it would. The only thing I see it harming is your hearing if it's too loud.

Could there be an ecosystem almost entirely composed of different species of human? If so, what would have to be done in order to construct such an ecosystem?

No, I don't think so. Homonids can't photosynthesize, and they can't decompose dead tissue, and they can't fix nitrogen, and they would make poor pollinators, and they can't breathe underwater.

There are many humanoids currently in existence.
However only one will be dominant and most likely (almost) genocide the others.

he was a fucking genius working in almost every area of math in his time. you can catch a glimpse of it in wikipedia: https://en.wikipedia.org/wiki/John_von_Neumann#Mathematics

the von neumann architecture thing is true though
>>
umm he invented modern game theory

he was, along with dirac, the first to establish a rigorous mathematical basis for quantum mechanics

created, with Ulam, Cellular Automata, the Monte Carlo algorithm

has many accomplishments in set theory, ergodic theory, lattice, operator theory etc.
and although not mathematically related, was the man that created the concept of MAD (Mutually Assured Destruction) and helped us prevent Nuclear War
