Anyone heard of Collin from MAKE? He has a video entitled Brainwave Beats on Youtube. I'm pretty sure he used a device called an EEG to create music. How does an EEG (or a plain electrode for that matter) extract signals from the brain? Information within the brain is sent via electric...

I believe tesla is the greatest mind who ever lived, even better than Einstein, and even Edison! But most of the people I know didn't even know who Tesla is before I told them, so not much of an opinion. So, let's have a conversation with people who are interested in science. What do you think...

All, Forgive me if this is not the right area of the forum, but it seems like it might reach the broadest audience here. I am looking for an introduction to computer hardware (and perhaps more generally, modern electronics) for a scientist. I am looking for something beyond what one might...

Homework Statement My question basically wants me to write the direct product of rings R = \mathbb{Z}_3 \oplus \mathbb{Z}_5 \oplus \mathbb{Z}_5 as a direct product of matrix rings over division rings. Homework Equations Relevant theorems http://img713.imageshack.us/img713/8471/g7pn.png...

What is the mind considered to be in physics ? Is it just a collection of thoughts ? And has there ever been any studies done on the mind and matter manipulation ? Appreciate all replies. Physics is Phun

Evo don't you dare close this thread I want at least one answer as to why it can or can't work :P So sinse we can strap electrodes to our heads and with nothing but thought, we can make something happen, whether it's moving a rats tail, moving a ball bearing or making someone elses finger...

From, ''Cognitive Neuroscience: the Biology of Mind'': A patient has a terrible time seeing everyday objects but has no problem seeing faces! In fact, if the faces are composed of fruit arranged to look like a face, the patient says he sees the face but does not realize it is made up of...

Last night I had a dream so vivid I can still remember every action and emotion, really unusual. It was about a major worldly crisis, I was in a large house and the outside had completely flooded with water filled with ice and people were dying in it. My boyfriend and parents were inside and we...

Mind boggled in regards to how S.A.T correlates with "intelligence" I apologize for posting this here but i was hoping for an intelligent discussion regarding the SAT. Doesn't the SAT just prove how knowledgeable you are? Because I've solved quite a number of problems, but have also failed...

I'm taking Calculus 3, differential equations, linear algebra, physics 3, and a putnam exam preparation class (self study under an adivsor). I will be expected to take the Putnam this December. I could take Computer Programing I instead of one of the math classes and the Putnam class. Is this...

Alright, let's get down to business. How important is it for you to be the best and sexiest scientist. We may be spending a lot of time in the lab but how much time are we spending sculpting our bodies at the gym :wink: and the mirror every morning! Also, feel free to comment and...

When the word "light" is mentioned what comes into your mind? When the word "light" is mentioned what comes into your mind? Not only the basic definition, list everything you can think of. No need to explain. The purpose behind this is I'm creating a massive mind map and want to make sure I...

I was dealing with the derivation of Stefan's law from Planck's law. In this derivation one gets to the following equation \frac{xe^{x}}{e^{x}-1}=5 At this point most places I looked provide an aproximate numerical solution to this transcendental equation and carry on. But I wwas thinking...

Are F1 control arms, upper/lower designed to supply an amount of downforce or just the ability to cut through the air with as little interferance as possible? I had seen a photo recent and it got me woundering. Maybe someone can explain Cheers

I am traveling at 50% C in a rocket ship. My buddy passes me at 51% C in a rocket ship. Assume my buddy is doing long division, & it's required that he writes down his work on paper. Let's go off on a tangent here. Relative to our prehistoric ancestors, the human mind today is far more...

The lecture in question... So what happens if I actually build this circuit and hook my fluke to it? How can moving my meter from the right side of the table to the left change my voltage reading if the circuit and my meter's connection to it is untouched? What happens if I put the meter...

I have been at battle with myself for the past year trying to find myself and find what it is that really fires me up inside. I recently got interested in engineering. More specifically mechanical engineering. I have two friends, one a Chem E and the other Mech E. The ME loves his job and works...

If human brains can be mapped to processors, I will definitely have a single core processor. I have a one track mind. I can only focus on one thing at a time. I see people working on many things at the same time. But I cannot do them like that. I work like a serial computer. My algorithm goes...

Hello, this is my first post! I came here with a question- and I bet I will continue to have more. I hope this is a good place to seek answers. I am not a physics major / actually we didn't even have physics classes. But... I did an experiment the other day after watching a video about...

How bad is my statistics knowledge based on the following mind map? Any concepts which aren't bold are the concepts that I know; the bold ones are the ones I'm currently learning. The mind map in question: http://i.imgur.com/4He3f.png What should I learn next based on my current...

1. In daily life, people are often praised for maintaining some particular point of view for the courage of their convictions. A change of mind is seen as a sign of weakness. How is that different in science Homework Equations Well I was reading something at one time that Einstein...

Most nervous systems use electrical signals from the brain to control the body. Could one not theoretically interface a computer with the first vertebra to override commands from the brain, and control the body? I'm sure that biologists do not yet understand the nervous system enough to...

I wasn't sure if this is the right section to put this, but I didn't notice an obvious alternative. Anyway, I've been wondering about the mind. We're made out of loads of little bits of ordinary, inanimate matter. Somehow in this universe it is possible to take some particles and carefully...

Hello all, Long time reader, first time poster ;) I'll try to keep it simple: I'm separating from the Air Force in January and I'm 99% sure that physics is the right academic/career choice for me. I'm curious if anyone else out there has had a similar experience as the one I'm about to...

This is seriously the most amazing thing ever. Pretty cheesy experiment, but amazing results. It still makes no sense to me how an observer completely changes the outcome. Its like the electron has a mind!

Okay. A few questions. Is there an escape character similar to '%s' which uses an NSString instead of a C-style string, so I could do something like NSLog(@"Hello, %N!",/*Insert NSString* here*/)? I tried the following code: #import <Foundation/Foundation.h> @interface Greeter ...

How can we calculate [via an equation] the number of pea-pods hit on a zombie in a given interval of time. for those who haven't played the game its briefly this: from point A to B, on A there is a pea shooting plant [constant position]. on B a zombie is closing in with constant velocity...

do you think that mind and matter are the same thing ? or two different things that somehow interact , conssiusnes , mind, being in a " higher level" and matter being the body in physical space ? i believe that they are the same thing , basing my arguments in the fact that all livinig...

hi all, i want you to post best mind boggling/twisting questions you know of. Thanks dpa

your vote... might not count?

Can an electron have a mind of its own?

By now, I've listened several times to Brian Greene's talk about the OPERA experiment. And, although I largely agree with him, there's one nagging question I have: Gravitation was, at a time soon following the Big Bang, a repulsive force. The existence of "Dark Energy" suggests the...

What is a move? (with these superfast neutrinos in mind...) When you go to a big restaurant, there are at any given time probably a certain amount of waitresses. It might be, one of them brings a soup, another a coffe and the third the bill. But they all represent the other reality, the other...

Dear all: I knew the coherent state is the eigenstate of annihilation operator with a complex eigenvalue, which seriously disturbed me of thinking it. Can anyone give me a simple and understandable picture of what is it, thanks a lot in advance.

Four friends A, B, C and D are buying a car together. They agree that everyone should have one of the first four trips all alone. But the following conditions apply: 1. If D is allowed to get on the first trip, C would have the third trip. 2. If A or D take the second trip, C would...

According to Einstein's theory, the fastest speed in this world is the speed of light. let's break this role for a sec. so here is the experiment: imagine a sphere moves infinitely quick relative to us. as quick as if its omnipresent, it seems appearing at every position at each time...

hello every1, From a very small age, i had a vision in mind to bcome a scientist, researching in physics. From time to time, Different parts of physics were adored by me. From cosmology, astronomy to quantum physics, I've always wanted to leave a mark in all of those fields. But when i...

First of all, I apologize if this issue has been covered before. Would it be accurate to say that, given that a neuron is either in a resting potential or action potential, that a binary model would be representative of the neural structure human mind, or would this be too simplistic of an...

Hey, I'm new here to these threads. I am currently attending community college. I came in as an engineering science major at my cc. To start things off, I dropped out of high school when I was 16. I felt like my high school was a joke which it was. I never learned anything. I was suffering from...

any one know any thing about the subconscious mind,i think it is part of a higher interlect in ones brain.but what do you think.

Homework Statement The height of a helicopter above the ground is given by h = 2.90t3, where h is in meters and t is in seconds. At t = 1.75 s, the helicopter releases a small mailbag. How long after its release does the mailbag reach the ground? Homework Equations I used xf =(1/2)at2...

As in the case of fear how does thought stimlate adrenal glands? Not so much thought but the instant recognition of a threat causes the release of adrenaline. But there must be an electrical event which is recognition. EEG's show this. But there must be specialized receptors for the...

Logical AND and bitwise AND...dull mind Hi, I had read some descriptions about these on web but i fell, both doing same thing. More, i observe these are changing language to language. Can any tell me straight difference with example.. that would be helpful to me.

I have two big problems in my mind about hydrogen bond for many years. I have checked many textbooks but all of them fails to explain what I don't understand. 1. To form a hydrogen bond (particular strong attraction) Why it is necessary for a hydrogen atom to attach to a highly...

Hi guys. I'm a high school drop-out. I went back and got a General Education Development degree. I'm also doing grade twelve courses because I want to goto university and study engineering. My math is very weak but I feel if I work hard I can catch up. Right now I'm doing "Calculus and...

This is a simple question I have because I am looking at a particular engine cycle, and I can't seem to think of its name...thus it is very difficult to search for discussions of something you don't know the name of. I'll describe the cycle, if anyone knows the name of the cycle please let me...

i am not much into biology but i have been reading about brain and mind ,i still don't get a satisfying answer,hope u people could help or give a link that may b useful

Although the title mentions biology the answers I need are from physics. If I have understood it correctly Argentinian Electroneurobiology assumes mind to take place at the actions of a force field overlapping the electromagnetic field of the brain. I think. An exposition...
