I don't have a background of physics either - it's just a hobby
  Quote:Hmm I would also like to address a dilemma of mine to get
  your opinion. You seem to want to know alot of things like me
  But how did you pick what you wanted to study out of all the
  sciences there are Hope it doesn't disappoint - I'm an "amateur
  scientist" - in other words - self-taught - always reading,
  always thinking, always exploring. I think you should have at
  least an "Intro-To" course in ALL of the above. I never finished
  college, but I did take a some AP Physics in high school, took a
  bunch of psychology courses in college (regular psych, abnormal
  psych and two child psychology courses), took AP biology in high
  school but didn't do well in that. Took two courses in
  sociology, never took a philosophy course. But It's important to
  read the "Cliff Notes" of all the Greek philosophers - maybe
  Wikipedia, or one of other websites that gives a basic synopsis
  of each of the greek philosophers and what ideas they came up
  with. What's cool about it is that it'll all seem VERY familiar,
  because a lot of modern philosophies and religious thought stem
  directly from them. [even Buddhist ideas took from the Greeks on
  some things - they weren't isolated societies believe it or not]
  If you take an intro-to course in each of them (or if you're
  lucky, you'll find a "comparitive science" course of some kind)
  - you'll know enough to have a global overview of the major
  ideas that shape the world of thought. Get hooked on every
  Science Channel (or Nova or PBS or whatever TV stations you have
  around) you can find. Go to your public library where the DVDs
  are and rent every science DVD you can find, ESPECIALLY those
  from the BBC (they do the best job at these things at explaining
  it all). Don't be afraid of the older ones (like Cosmos from
  Carl Sagan) - even if they don't mention dark matter or dark
  energy in the older videos, they're 99.44% accurate (because
  there haven't been a heck of lot of modifications of the various
  cosmos theories since the mid 1970's - they've just added new
  ideas on top of them). Youtube has a lot of great short videos
  as well - a lot of B.S. is there (like the "what the __ do you
  know?") but it's easy enough to figure out the good from the
  fluffy "sounds-too-good-to-be-true" stuff. Basically, just like
  you are doing, it's good to work on getting a basic
  understanding of what they've already figured out, and
  especially, what questions they DON'T have answers for. I just
  read a book called the Five Unanswered Questions of Science
  (something like that) which goes over five questions from five
  schools of science that there's no answer for yet. I never took
  any math courses in college 'cause I took my interesting ones,
  managed to CLEP through the basic Math and English and when I
  dropped out, I never did get around to taking any more math
  courses. It's also important, I think, to get a "feel" for
  history that DOESN'T start in 1776. The biggest breakthrough for
  me is when I was church-hopping (it was my thing - it's not
  everybody's thing) and I ended up in the Russian Orthodox Church
  for a year or two (I almost became a monk, believe it or not -
  even though I'm not Russian). The fact that it was a religious
  thing is besides the point - what they did for me is give me an
  ALTERNATIVE VIEW OF HISTORY that wasn't Western in origin. I
  started to see a continuous line from the ancient Greeks through
  the Western Roman Empire (which the Greeks take all credit for
  inspiring) and when Rome fell, the Eastern Roman Empire in
  Constantiple continued (along with advances in science and math
  and philosophy) and a generation before Constantiple fell in
  14-something (1466 I think) to the Ottoman Empire, people
  escaped from Constantiple and started up secret schools in Italy
  - and these are the schools that brought the ancient knowledge
  back to the West and started the Renaissance and a revival of
  ancient Greek philosophy, science, art and culture. I no longer
  think of the Puritans as ancient history - I see them as modern
  history. I see Columbus as modern history. To me, ancient
  history IS 500 BC. It's a "sense of historical time" - once you
  get that - a feeling that the whole of history is accessible to
  your brain, where you can sense the chain of thought that moved
  from one generation to the next, from one culture to the next -
  THAT'S when you start really getting a really solid view of the
  nature of things, because it no longer seems mysterious or
  obscure. And get your B.S. detector locked and loaded. There's a
  lot of it out there, and if you know the history behind things,
  you can really sniff it out when you see it. What psychology
  helps do in this case is have COMPASSION for people who are
  following a weird philosophy or spirituality
  lock-stock-and-barrel and let them believe what they want to
  believe, for they do not know what you know. You see their
  beliefs from a historical perspective - as an outcropping of the
  ideas of various people who lived throughout the millenia.
  Example: See Ghost Hunters? I don't watch it 'cause I've been
  there, done that. Ghost Hunters/Paranomal < X-Files <--
  Poltergeist <-- The Exorcist <-- Chariots of the Gods (1960's
  book - read it if you want to see where the "pyramids are built
  by aliens" idea and crystal skull stuff came from (I am a
  Stargate fan so I love that stuff, but I don't believe it) <--
  spiritualist movement of the 1920's & 30's (Edgar Cayce was one
  of them) - and Quantum Physics and Einstein had a great role to
  play as it mystified people back then too, bringing back their
  faith in ghosts) <-- the discovery of electricity and finally
  back to the discovery of magnetic fields in the 1840's ---
  THAT'S when the modern movement of "ghosts" and possessions
  began. People were mystified by "fields" (I stlil am) - and a
  lot of strange religious/spiritual ideas of the time are based
  around fields and electricity and photography and a major
  immigration of Gypsies into Europe and the USA all mixed in
  there and they started going from town to town with the
  carnivals bringing the idea of "mediums" to people, who them
  started their OWN groups trying to contact the dead. Go from the
  mid 1800's through to 2008 and you have Ghost Hunters. It's
  harder to explain than it is to understand. What I wrote makes
  sense to me but I probably would have to expand my
  run-on-sentences into a few pages to really explain what the
  heck I'm talking about. It's just that, the more you understand
  PEOPLE, WHY they think the way they do, WHY they act the way
  they do, WHO influenced them at that time, WHAT was "the
  uncertainty" of that particular era - things start to come
  together in your mind, and it keeps you from having a blind
  faith in anything, except for what "makes sense" to you. Beware
  of groups that have their own weird terminology that "just
  doesn't quite make sense". If they have to use special words to
  explain something and CAN'T MAKE AN ANALOGY to a common thing
  that's pretty much understandable - then there's a good chance
  they don't know what they're talking about. They just like using
  "buzz words" a lot. ::: off soapbox ::: Quote:Concerning what
  you said: So 4 dimensions exist? Time is subjective and does not
  exist without mind I believe. Does that mean there is no forth
  dimension? The measure photon movement you need other photons to
  do so. But with the interference of the other photons they end
  up in a unpredictable fashion. Which makes ppl beleive that
  observation changes reality, but it just changes the procedure
  which changes the outcome? Well, you can say "Time is the
  measure between events" (whether the event is the ticking of a
  clock in "one second increments" (therefore, time passed) or the
  sun rose and fell - two separate events - the "stuff inbetween"
  was time. I think there are five dimensions - four spatial
  dimensions PLUS time. I think time IS a valid dimension - I do
  not believe it is fully subjective. I think our PERCEPTION of
  time is subjective (when you are scared, time slows down, as if
  your brain is taking a thousand photographs a second and the
  measurement in the brain between "moments" is a whole lot
  shorter than when you're not scared. It's like filming a movie
  at high speed - you use up more film (take more pictures) then
  when you play it back at regular speed, you can slow motion. Our
  own brain does "stop animation". If every day is pretty much the
  same to you and nothing ever happens, your subjective sense of
  time is that there IS no time, BECAUSE NOTHING (no events) EVER
  HAPPENS worth recording in the brain as an "event". For you,
  there is no time. But if there is movement - if there was
  something that "just happened" but isn't happening anymore, then
  time happened. Of course, we could get into "WHEN IS THE PRESENT
  MOMENT?" or "When is "NOW?"" -- that's a mind-fk waiting to
  happen. (I picture time as a fat wooden bead with a piece of
  flat fabric going through its big center hole. Where the bead is
  moving forward, the fabric is PINCHED in the bead, leaving a
  shape like this: >< - the part where the arrows meet, that's
  NOW, the left is PAST the right is FUTURE. But the bead in
  reality is infinitessemly tiny and can't be stopped. Just
  experienced - whether it is human that is experiencing it, or a
  rock, or a star or a thought going through the mind. (the
  explanation of the photon was to show that we don't really
  change reality but rather that scientists that are throwing a
  photon at a particle to be able to measure its location figure
  out its location but end up banging it out of place so that it
  stops travelling the way it was travelling. Yes - I think you
  have the concept nailed down tight) ______ Kenneth Udut
