What research has been done on native randomisation hereustics in humans? I have heard of the 'pick any number between 1-10, from which people tend to pick 1,4 or 7, but what else?

Awesome, you have to try this.

1. Go to your kitchen and find a nice metal spoon. Tea spoons work but normal ones are better.
2. Get yourself a lighter, the bigger the flame, the better.
3. Get some duct tape and wrap it around the handle. About 4-6 layers.
4. Start heating up the spoon with the lighter. Make it really really hot. Holding it just above the flame for 2 minutes should work.
5. Go to a faucet and torn on cold(!) water at full force.
6. Hold the spoon directly under the faucet.
7. Post results.
8. ???
9. Profit

Ever see a blacksmith put something hot into water to cool it down? Yea, it steams and possibly hardens. The idea that it explodes is an old troll.

Greetings /sci/. permit me to wax philosophical.

the other day I was in a discussion with a few friends of mine, and during our meandering the topic drifted to “what is the essence of science?” in the media science tends to get painted with the same brush as religion. The body of information science has accrued over the centuries is seen as just another dogma some choose to follow. I find this viewpoint to be in error. The body of knowledge we can science, is not in fact science itself. Its the fruit, not the tree, as it were.

But if the body of information isnt science, what is? when I sat down to think about it, I found that the core of science boils down to two fundamental questions “Whats happening?” being the first question. But this is not all that different from any other philosophy that seeks to explain the universe. The true key to science, and the reason its served mankind so well, is the second question...”Are you sure?”

its that seed of doubt, and the process we've developed to address that doubt that has led us out of the dark ages. Many philosophies have a whole range of answers to the fundamental questions. But science, as far as we know, is the first viewpoint that inherently doubts its own answers. Science acknowledges the fallibility of human senses and insists its followers test they're conclusions again and again and again. And only when those tests have been thoroughly exhausted can a scientists say “we know whats going on here....we're pretty sure” peer review, the scientific method, parameters of experiments and so forth are all a means of accomplishing that one goal. To verify the truth of our ideas.

So, in a very real way, the core of science, its most basic indivisible unit, is doubt. And as it turns out, doubt is a very good thing to have when it comes to understanding the universe. More often then not our initial assumptions are wrong. Things are almost never as the seem in our world. And until your willing to acknowledge that illusion and see past it, you wont ever understand the universes deeper levels.

your thoughts?

>>>the fruit, not the tree
Seriously? Do you know the expression "Hitler ate sugar"?
If you're going to treat a common metaphor[1] as a bible reference merely because it happens to be in the bible, then all bets are off regarding the validity of your reasoning.

>the important part of that sentence was the phrase "singling out."
I still don't agree with that statement.
>The true key to science [...] is the second question...”Are you sure?”
>its that seed of doubt, and the process we've developed to address that doubt
>Science acknowledges the fallibility of human senses and insists its followers test they're conclusions again and again and again.
What he's singling out is clearly not the uncertainty of the answers, but the error-finding process that takes place after a possible answer is found.
(I realize that the "followers" bit doesn't help my case. I think it deserves the benefit of the doubt because he's making an analogy between science and philosophy.)

>he either doesn't actually believe or doesn't understand his own conclusion of what science is by directly contradicting it
Would this really be that surprising for someone who's only beginning to try to understand on their own what science is about?

fruits come from other plants too. when you talk about fruits and trees literally within 3 words of the word knowledge, people will take that as a bible reference.

i'm not going to say any more, because it's already gone further than it should have. i never claimed to be an internet mind reader or intended it as a serious accusation, just that he has phrasing and thought inconsistencies that can be interpreted as insincerity.

OP here.

well, this went in a direction i never imagined.

to my mind, the thought behind science is a philosophy. but its one that works. its rooted in physical proof that can be verified and tested. perhaps i should have been more explicit in my wording. most philosophies give you an answer but stop at that. Science gives you an answer, then encourages you to verify it. test that answer. poke it and see if we really understand whats going on.

to me, that willingness to test itself makes science unique. it accommodates human fallibility and the limits of our senses by encouraging us to take good, long looks at what we study. to exparament from every possible angle and verify what we see with others.

this is sciences virtue. it lets us see past our limitations by first acknowledging those limitations. no theory is ever complete. even phenomena that are well tread have room for revision as we learn new things. hell, newton had a pretty damn firm grasp on gravity in his day, then Einstein comes along and turns it on its head. perfect example of how the philosophy of science works.

to be absolutely clear: the body of knowledge science has accumulated is not a philosophy. as far as we can tell, its fact. the thoughts and world veiw that prompted us to collect that body of knowledge, and that makes room for its refinement, IS a philosophy.

Thorium is not fissile, so to make a reactor work you have to mix it with U235 or plutonium or provide some other source of neutrons (e.g. a particle accelerator) to convert it to U233, which is fissile. What you then get, as well as heat energy, radiation, and fission products from the Plutonium and Uranium, is U232. U232 (and its decay products) emit very hard gamma radiation.

Thorium doesn't give you anything new.
Btw, 7chan has a fucktonne of sponsors which it is giving my user information to, apparently, according to several addons I have...thought I should mention that

somewhat stupid question but here it goes.

what is the correct term for data stored on something like a computer, a flash drive, or any other electronic device. physically they don't really exist except as abstract bits and bytes.

I know digital isn't the right term because that just means not analog (i know analog is something that is measured analogously like a sound wave or hands on a clock and digital is measured absolutely like counting on your fingers i know it isn't electronically because that means via electrons (electricity is electronic!)

no, that's not what it means. analog means the scale is a continuous spectrum and digital means the scale has discrete increments of equal size.

as for the data, you have to specify what you mean by "like a computer." for example, anything that's on a hard disk, anything that's translated into binary, anything that's recorded and retrieved automatically and electronically, etc.

I don't believe they have to be of equal size. It just makes it a lot easier to handle.

bro, that's literally the definition of interval scale, which is what analog and digital are used to describe

Hola again /sci/, coming to you with a weird request.

im participating in a superhero themed role playing game, and the idea i had for my characters powers was the ability to "ascend" or "descend" into higher and lower spacial dimensions.

in "normal" mode he's just a regular human. occupying the 3 familiar dimensions we all know and love. but what would be be able to do when he "ascends" into 4 space, 5 space and so on? what kind of powers would being a 5 (or higher) dimensional being give him when interacting with your 3 dimensional space?

its a bit weird i know, especially to ask something like this here. but i was hoping to have a few grains of truth in an otherwise fantastical character. or at least be able to use the jargon without looking like a total idiot.

thanks for your time!

look at a mobius strip (or a hotwheels track). to a 2d guy on the surface it seems like a circle, but in 3d you can see it's not. the point of this example is that the magnitude of the velocity of something travelling on the track is the same in 2d and 3d, but the direction is not.

Basically whatever a ghost can do, if he can only manipulate himself in and out of these dimensions. Invisibility, invincibility, teleportation.

Imagine a stick-figure guy in a house drawn on a piece of paper. He is constrained by two dimensions, and thus has to walk around the lines of graphite on the paper to navigate his house. Now, picture an ant walking across this piece of paper. To the perspective of the two-dimensional man, the ant can walk through walls. Furthermore, he can only see the very tips of the ant's feet when it touches the paper — that is, where and when the ant is interacting with his dimension. He wouldn't at any point see an ant, he would just seem nebulous blobs of matter teleporting across the rooms.


It's entirely possible that the part of human beings that we can see and interact with (that is, the flesh and blood) or indeed all of reality "extends past" the three dimensions we are familiar with. This gives a possibility of truth to the human soul, which is the part of the human being that exists in higher-numbered dimensions and thus cannot be killed or even really affected, here.
