Hi Guys, fresh meat here. I have a simple LED series circuit I'm currently playing with. 700ma forward voltage leds at 3.3v (blue) and 2.2v (red). Its working fine, I have it rigged to a 19.5V power supply and a 2.7 Ohm, 25 W resistor. I need 15.4 out of the 19.5, meaning I have to...

Have you read it? If so, why? Do you agree with his thesis that the crisis of the University is really a crisis in philosophy?That is hardly studying philosophy. Students now arrive at the university ignorant and cynical about our political heritage, lacking the wherewithal to be either inspired...

Hi, I've been thinking about this topic for a long time and found a lot of info on the web about it leading me to believe its bound to happen soon. More Info : http://en.wikipedia.org/wiki/Mind_uploading Apparently it's entirely realistic, but I can't find an actual ETA, for example...

Hi I'm now reading about Vector fields, everything is clear and intuitive for me as curl divergence ..ect , except one simple thing that I'm straggling with for the last 4 days! I searched Internet and a lot of math & physics books but in vain : Why Conservative field is Path independent...

I don't mean the actual definition of the Euler-Lagrange equation per-se, but rather a word definition that's slipping my mind. I remember that if you want to measure the shortest distance between two points, you have to minimize an integral of all possible paths or something. Is that thing...

So, I'm assuming that scalars are what I'm used to working with in math. You add, subtract, multiply, etc.; they follow the rules I know. 1 + 1 = 2. Scalar = Magnitude Vector = Magnitude and Direction Now, how do magnitude and direction coexist? Right now I'm just seeing some scalar volume...

Is it something which is able to accept pretty much any subject matter in relation to this message boards rules of conduct and intent? Unlocked. Curious. Interested.

How do scientists collaborate to understand such complex systems as missions to Mars, the world economy, the Internet or the human genome?

I'm watching right now on NOVA (PBS) : Here's the website

A bit off the wall, but anyone who plays with random number generators quickly learns that it is impossible to make one that is truly random, using software alone. Has anyone ever considered whether people can actually generate random numbers? How does the mind produce a number "randomly"? Do we...

The current issue of NYRB has a review by John Allen Paulos, of a book by Masha Gessen entitled Perfect Rigor: A Genius and the Mathematical Breakthrough of the Century. (Gessen's book is about the Russian mathematician Grigory Perelman and his solution of the Poincare Conjecture.) Speculating...

Mind wandering is good??! You must have read on various news sites http://discovermagazine.com/2009/jul-aug/15-brain-stop-paying-attention-zoning-out-crucial-mental-state http://nervoussystem.suite101.com/article.cfm/is_a_wandering_mind_a_bad_thing and blogs recently that mind wandering is a...

Hello as an ordinary guy that is not a talented human,I always wonder what happens in mind of a genius human that does not happen in mind of an ordinary human,for example i have a friend which is a really talented boy and one of those to be said among top 0.5% of society,everytime we sit...

From Wikipedia talk page on time travel: Do you believe this statement? "If the human mind can think it, it can be done"

It seems to me a lot of what quantum mechanics is essentially saying is that "causality of any given event is equal and opposite to the causing event" - leading to entanglement. This is in some way analogous to the Newton's laws of "action and reaction are equal and opposite". What I...

Alright, here we go... First off I just want to warn you all that I'm very bad @ math, so this might take a little explanation. I'm currently in a Gen Chem class and can't get a grasp on this Stoichiometry stuff. One of the ?'s I'm looking at is this: 1.2g AgNO3 + 0.5g Cu + 100ml H2O --->...

please help rite away , might be losing my mind A skier moves at 23.0 m/s down a 24.0 degree slope and encounters a region of wet snow, where the coefficient of friction = 0.680. How far down the slope does she go before stopping? thats how the problem is exactly, i drew a free body diagram...

Hello, I'm a physics Major, and I want to transfer to another school. I have 4 choices: University of Wisconsin - Madison University of illinois at Chicago Indiana University Bloomington Purdue university here is what I would consider: I'm a physics student but what's more...

Does psychology have the same potential as a healing art as physiology has?

a funny question into my mind. If you are completely isolated from all environment, will you become just wave function spreading all over the space (or universe whatever)?

Problem from "A Beautiful Mind" In the movie when he first walks into teach that ad cal class, this is the problem he wrote on the board (verbatim): V=\{F:\mathbb{R}^3\backslash X\rightarrow \mathbb{R}^3:\nabla\times F=0\} W=\{F=\nabla g\} \dim (V/W)=? What's X?

Hi, Let me start off by saying I am new to the forums I just discovered them last night and just made an account. I find these forums to be an execellent source of information and guidance to anyone looking to gain knowledge on physics. I'm 17 years old, going to be a senior in high...

Hi! I would like to learn programming (I'm a beginner except for some programs on my calculator), and I need help. I had in mind to begin with C++, but I don't know of any good compiler for Windows. If anybody knows of one, and could tell me how I use the compiler (the language itself I can...

Hello everyone. I am new here so let me say what I said in my first post first... Hello everyone, before I start, I just want to say I’m a little out of place here. I am not a student of physics or cosmology, and I am definitely not a professional at anything scientific. I am an artist and...

Hi , A friend sent me this website, and I was wondering how it worked, http://www.regiftable.com/regiftingrobinpopup.html obviously it can't read my mind, and its some kind of mathematical trick, I can initially see that all the answers i come up with are 18 apart and that gift is...

What is the most mind blowing thing you have ever seen that's physics related. I want to hear things that i never ever thought was true. things like "Because of the uncertainty principle, when you try to prove something is made of matter, it is true, but when you try to prove something is a...

Yikes! :bugeye: http://www.youtube.com/watch?v=vMG-LWyNcAs&feature=fvhl

there was some thing on the news not long ago and i would like to find out what has happened in this field folks are takeing med that tho made for some other condition are enhanceing their abbility to thing better and be more on "their game" then normal and that the military has also been...

Right now, I kind of only have the option of doing engineering for my bachelor degree, but am more interested in physics. Is it possible for me to do my engineering course, and study a full fledged physics course on my own at the same time? Or even before that, is it possible for me to...

Mechanical Engineering Project, Need A Creative Mind! Please Help! Ok well I think I've figured out what I am going to do for my project, but I just need a little help to finish it off. So the idea is that there is a semicircle fountain/pond and we have to build an object that will get an...

"mind" as a noun If we were all to come to the agreement that the mind is what the brain does (not that I know that we will), would it still make sense to still use "mind" as a noun? To try an analogy, "running" I suppose, makes sense as a noun and running is what the legs do. But "mind" and...

A lot of humans like Chris Leagan, the man who everyboddy says has the highest IQ on the planet , seems to think so. I disagree with him . I think our intelligence limits us from visualiizing the whole universe as it really is. Just as like an ants mind would limit it from imagining a 3...

http://www.msnbc.msn.com/id/29298315" He is one of the innocent Obama appointees. The idea here is that you put a gps in your car that records how many miles you've traveled. Then when you go to the gas station, they read the gsp and you pay based on the number of miles you have travelled...

Clark and Chalmers co-authored a paper , “http://consc.net/papers/extended.html" ” in which they ask the question, “Where does the mind stop and the rest of the world begin?” The intuitive response is to suggest the mind is supervenient only on the brain and not on any external part of the...

Let's use the analogy of the brain and mind with the computer and its software. We know that the physical brain is the product of evolution and genetics. What then can we say about the mind (software), it's origins and it's development?

first off... Awesome forum! i have been looking for a forum like this for... too long ok... here is a list of the long term effects I am having... short of breath it seems that without concentrating on breathing my rate is incredibly slow zoning out constantly i feel as if I am looking...

Last night i awoke in the middle of the night to find that my bedside lamp was on. How is this possible? I don't remember turning it on myself and it's not a touch lamp. It really freaked me out. Is there anyway that it is in fact possible for it to have turned on?? Any help would be...

It was thought at one time that the right brain processed all our subjective thinking (stuff like intuition, perception and interpretations of our experiences) while the left hemisphere was responsible for performing objective thinking (logical, analytical). I think I've read that with MRI...

The Exodus Frame of Mind Recently David Brooks wrote for the New York Times an article labeled “The Past Meets the Future”. This was an imaginary conversation between Mr. Past and Mr. Future. Mr. Past focused upon our failure to understand the past and in so doing we make egregious...

Ok, I know I'm not losing my mind. But I am in a discussion with other people in another forum. My theories are a little whacked compared to the norm. I know I saw the discovery channel and an eastern european scientist (i think czech) created some electromagnetic anti-gravity field or...

Since the human mind has a relatively large degree of freedom, it can do things on its own will. How does the human mind fall under the laws of entropy?

When you begin your transitional period from student to professor. I bet most of you will say during your graduate studies or even beyond that stage of learning

Would it be possible to say that the brain in some aspects has nothing to do with the functionality of the mind? For me personally, I don't care how my brain works, it's totally irrelevant for me living my life, but what does this mean? To me it seems obvious that we have to separate the mind...

Hi I was wondering if you guys know any VERY cool labs I could use? I want to demonstrate the lab to my student body and i want it to interest them very much so we get more students interested into sciences.

Perhaps someone can offer me some opinions; I don't really know what to research at this point. My mind absorbs the world like a sponge and I have a photographic representation of my entire life going back to 5 years old, with a few memories going back to 2 years old. My memories are as...

[FONT="Comic Sans MS"][SIZE="3"][FONT="Comic Sans MS"] How can I Improve my problem solving skills using my mind only?

Are mental phenomena such as experience, thought and qualia just an epiphenomena? The "exclusion argument" per Yablo: Ref: Yablo (1992) "Mental Causation" To put it even more simply, the cause of a switch in a computer changing position is due to the local affects of voltage on that...

Im curious if anyone knows if it is theoretically possible to place the human mind into an infinite loop in a similar manner to the placing an electronic computer into one. If not, why? What is principle physical/neurological process that prevents this from occurring?
