    When was the earth formed?

    Thanks a ton!

    When was the earth formed?

    I guess it'd be hard to tell when the earth became the earth, so I suppose a better question would be; 'How long ago was the earth able to support life?' I've read that life has only had approximately 200 million years to get to where it is today because of the period of heavy bombardment which...

    Conductivity reference charts

    I needed to revise my post; I didn't understand exactly what the chart was diagramming; this is the first chart I saw; http://www.tibtech.com/conductivity.php. (I'm still unsure what the commas and 2 values represent) In the past, my physics textbook and internet reference charts have...

    Conductivity reference charts

    Does anyone know where I could find a good chart listing the thermal and electrical conductivities of metals? The chart doesn't need to be terribly accurate, I only need to know general values for comparison to other metals on the chart. All I need is one basic value for each metal. If anyone...

    Nickel-penny composition for voltaic cell

    I was organizing pennies into categories based on what they were composed of; before 1982 (I believe) pennies were made out of 95% Cu, and after they were made primarily out of zinc. I thought that the ideal penny for a voltaic cell would use a Copper penny, and a Nickel. However, I found that...

    Confusion about relativity

    I'm addicted to using my brain; using logic and reason to innovate and manipulate established ideas is my best way to learn, and I love to "waste my time" doing it, but yes, while there is soooo much that I am ignorant of, I shouldn't post and share them with anyone that is unwilling to correct...

    Confusion about relativity

    When I first started reading up on physics I thought I understood it all, then someone told me that time is relative, and i went through a long process of disillusionment. After I thought I understood time being relative, I proceeded to develop a series of theories based on what I understood...

    Boat hippie crackpot hydrogen rant?

    I found it! It was by "sailboatmd" here's the link; https://www.physicsforums.com/showthread.php?t=7586&highlight=sailboatmd Please don't delete it, I use it often as an analogy of the dangers of ignorance, and the stress that comes with a lack of understanding. Plus it's really funny =)

    Boat hippie crackpot hydrogen rant?

    I'm beating myself up about it a little bit, but I can't find the thread where that one hippie was ranting about how hydrogen power could destroy the world, and about how shipping oil from Saudi Arabia to the U.S. was throwing off the earth's rotation, along with a whole bunch of other unfounded...

    Velocity translating into weight?

    I also heard it mentioned that matter and anti matter can be created with just energy, how?? What form does the matter and anti matter take? When/if they recombine, does it generate the same amount of energy that was required to create it, or are there byproducts of the whole anomaly?

    Velocity translating into weight?

    I accidentally posted this under another forum user's topic, sorry about that :frown: My question was regarding matter gaining mass when it is accelerated. My question originated from an explanation of the large hadron collider; the explaination stated that when the protons in the LHC are...

    Large Hadron Collider questions

    Thank you, thank you, thank you, that clarified a lot. my curiosity about all this has been like a bad itch, thanks for scratching it! :biggrin:

    Large Hadron Collider questions

    I watched some interesting videos on the Large Hadron Collider (LHC) and it raised a whole ton of questions. If my questions do not make any sense, perhaps the video itself, though clever and catchy, is not credible. ( http://technology.todaysbigthing.com/2008/09/11 [Broken] +...

    Observations takne at the speed of light

    the question I asked wasn't very specific, what i am really wondering about is when we travel very very quickly, not at the speed of light, but very fast away from a light source, wouldn't the wavelength of the light coming from the light source become so long that it is outside of the spectrum...

    Observations takne at the speed of light

    I've heard the concept of an observer traveling at the speed of light, but when i placed myself in that observer's shoes i came to wonder; If someone was actually traveling at the speed of light, would/could they SEE anything at all? wouldn't the wavelength of the light be outside of the...
