Thoughts Definition and 339 Threads

A thread for new or used Deep Thoughts. Here are a few from my collection; not in the true tradition of Deep Thoughts, but it's a start. - Unknown – an ancient Chinese proverb. - some guy's shirt on TV - Robert Stack; Airplane. - Carol OConner; All in the Family – unknown biologist -...

Why is it that a spring exerts a force -kx on a block? Is it because the atoms making the spring themselves are in a stable equilibrium when the spring is at its relaxed lenght, but as soon as it is stretched, for small displacement around the equilibrium position, a "locally hookian"...

I entered university fall 2004 to study engineering physics. The course program was quite interesting and I am pretty satisfied with what I`ve learned so far. But i think i don't have that much interest in all sorts of machines and stuff like that. I could say i like calculus and pure math more...

Just an idea: It occurred to me that people can't see the fourth dimension because, in reality, we can't even see the third. Think about it. When you're looking at something, each of your eyes registers a 2D image, and the sense of depth (the third dimension) is inferred from the two 2D...

My question is: A 3.00 uF and a 5.00 uF capacitor are connected in series across a 30.0 V battery. A 7.00 uF capacitor is then connected in parallel across the 3.00 uF capacitor. Determine the voltage across the 7.00 uF capacitor. Ok, there are two situations, one with the 7 capacitor...

Well while studying i frequently have negative thoughts like i cannot do it, i don't have time , and feel low in confidence it has caused much trouble to me what should one do if he has this problem. Thank You

Hi, I have some different ideas that I feel belong in this particular forum. Instead of making a new topic for each separate idea, I decided it might be easiar on everyone if I just posted them all in the same thread. This way if/when my ideas aren't appreciated by someone then they don't...

There was a section in Greene's book that actually helped me form a curious idea about the origins of the universe and I wanted anyone's thoughts on it. If there was only one Big Bang, then shouldn't there be a concentration of matter/gas in the region of the center as everything spreads in all...

Now this next post is actualy connected to my previous post about light speed. Now what the light speed is infinite also shows is that there is no external time what so ever. What i mean is the big bang is happening right now just as the possible end of the universe is happening right now...

Submitted, for your consideration, three thoughts regarding the concept of morality: 1) Morality is not defined by what is natural. Since many natural occurrences are morally wrong, morality must be a concept apart from nature. Further, since some natural processes are morally right, we...

Are there any charts or information on how temperature-hot each nuclear material gets along with it's half-life and the type of radiation it releases (a, b, g)? Thought about this from one of the nuclear meltdown threads...

A lot of my friends seem to be concerned about the government interfering and watching over our daily lives, but what was surprising to me was to find out (through a new documentary) that major news organizations are also playing a part, though much less publicized (because ironically...

Greetings! I am asked to do the following: Simplify (A^{-1}B)^{-1}(C^{-1}A)^{-1}(B^{-1}C)^{-1} for (n x n) invertible matrices A B and C. You see, I was able to show that the result of this is simply the identity matrix I_n by selecting 3 (2x2) matrices A B and C that were invertible...

Predisposition's aside, I've been thinking about a whole bunch of stuff. I'm not even sure if they're questions. 1) If we assume when a spaceship is moving at the speed of light, it has infinite mass. In order for a ship with infinite mass to move, it would require infinite energy. Since the...

Patrick posted the following interesting link in another thread: I'd like to discuss this some more. Whenever I have read about these experiments I have always hoped to see the results of one in particular but I have never found what I wanted. I can guess what the results would be, but...

First off, I don’t have a phd, I am not a scientist (hehe well I am a comp programmer and i know some of them to claim to be scientist) My skills and basic understanding physics, classical and quantum are weak compared to the people that frequent this forum. I actually found this forum while I...

Are our thoughts real? Often, I will be thinking of someone and then later bump into them. Or I will have a dream about something that actually happens the next day. Sometimes when I focus on my thinking long enough about someone or something coming into my life, it happens. Or even better...

I would like everyone to comment on this. What do you think is the speed of gravity? Some say it’s the same as the speed of light, others claim it might be 20 billion times faster than light. What is your idea? :)

I suppose someone has thought of this but is the supposed "interference" of light particles in the double slit experiment actually only the apparent interference of light particles and actually an interference of paths open for the light particles to travel? I. e. it is something else creating...

I recently graduated with my Physics degree and am now employed by a company that designs and manufactures unmanned aerial vehicles. I was just curious as to what some of you thought about the whole idea. Some of our vehicles are posted on our internet site incase you want more information...

What would you do if you couldn't stop poeple from hearing ALL your thoughts... and no.. you can't say I would stop speaking and just write things down... it is something you can't stop, unless you stop thinking =-P :eek:

Do you watch 'Bollywood' films? Do you think they're a rip-off? Or are they great for comedy value :smile: (whether intentionally or not :wink: ) ? If you've watched one, you've seen them all? :surprise:

Saddam's Thoughts On The "Palestinian Issue" Just to highlight how "out of touch" the West is, I'm reproducing a certain speech from one Saddam Hussein. I know I've posted it before on this Forum, but it's VERY RELEVANT now! From...

Sitting here on this cloudy, rainy day causes my mind to wander. In the voids of space, with no atmosphere, is it cold? If so, how? I thought cold was a measurment of AIR temperature; if no air, how could it be cold? Also, if Spring is nearing why don't I feel more enthusiastic about things...

I think that subconscious minds are our minds that havn't been tainted by society and such. If you trust your subconscious mind, then usually you will do the "right" thing for you. Now, theoretically speaking, there has to be a way that you can, in a sense "open" your door into your...

Heritability increases from about 0.4 in childhood to 0.8 in later adulthood. The way these heritabilities are estimated is through numerous experiments on twins, adopted children, longitudinal studies, inbreeding depression research, etc. Nothing in science can be proven however. We know of...

Is there any possibilites that we can command our computers through Mind?

Quantum entities are described as probability distributions, which are attributes of an underlying phase space, where the properties-attributes such as "spin" and "charge" are not the attributes of individual particles, but they are universally distributive entities, being the attributes of a...

Someone posted the following at alt.atheism: How do you know what happens after death? Have you been in that position? If we are the rational skeptics we ought to be, we will doubt that our perception of 'fleshiness', or materialism in general, is a complete and perfect perception. If we...

((also posted to General Engineering)) Hi everybody, I'm working on a concept for a movie that I'm making. It's a fictional movie, but the concepts in it are definitely grounded in current and theoretical science. Coming from a big science background, I of course want the fictional...

Here is the future of computing whether you like it or not! Here is a site that gives a great summary of what is in the future for computers. After reading this I would like to hear your comments on the topic..I hope this thread will become a real kicker))...

Well I am Christian so I beleave in the God of the Bible. Anyway that is bestides the point. Well my view of everything is this. The big bang was God speaking the world into beaning. My view of God is not so much as a all powerfull beaning but more of a Math Code that is alive and that is...

I'm reading Paul Davies' book: About Time:Einstein's Unfinished Revolution And I have lots of questions... FTL = t reversal ? page 177 'photons and a beam-splitter'... -quote- ...if both photon paths are the same the photons will arrive at the beam-splitter simultaneously and, for reasons...

I've just thought of something that may be completely wrong and is just waiting to be kicked down, trodden underfoot etc. Now a problem with BB is that the theory of it as a case of quantum fluctuations seems to require the production of a particle and anti-particle together, and our...
