E=MC² & Thermodynamics

  1. Oct 12, 2005 #1
    Any one have any thoughts on Thermodynamics or The amount of energy matter realy has stored within.

    Thermodynamics: The first law, is the conservation law of energy. It states that energy cannot be created or destroyed, and therefore the amount of heat transferred into a system plus the amount of work done on the system must produce an equal increase of energy in the system.

    Thermodynamics: The second law suggests the existence of an absolute temperature scale that includes an absolute zero of temperature.

    Special theory of relativity: the speed of light is A constant speed of 299,792,458 m per second.
    Describes an velocity energy barrier for motion

    E=MC² Energy equals Mass times the Speed Of Light Squared.
    Einstein proved that the speed of light was a constant of nature and the speed of light was the ultimate velocity in the universe.
    Imagine, for a moment, that you are in a rocket speeding at 90 percent the speed of light away from Earth. Now fire a bullet inside the rocket that is also going at 90 percent the speed of light. According to Newtonian physics, the bullet should be going at 180 percent the speed of light, thus exceeding light velocity. But Einstein showed that because meter sticks are shortening and time is slowing down, the sum of these velocities is actually close to 99 percent the speed of light. In fact, Einstein could show that no matter how hard you tried, you could never boost yourself beyond the speed of light. Light velocity was the ultimate speed limit in the universe. If meter sticks and clocks became distorted the faster you moved, then everything you can measure with meter sticks and clocks must also change, including matter and energy. In fact, matter and energy could change into each other. For example, Einstein could show that the mass of an object increased the faster it moved. (Its mass would in fact become infinite if you hit the speed of light—which is impossible, which proves the unattainability of the speed of light.) This meant that the energy of motion was somehow being transformed into increasing the mass of the object. Thus, matter and energy are interchangeable. If you calculated precisely how much energy was being converted into mass, in a few simple lines you could show that E = mc2, the most celebrated equation of all time. Since the speed of light was a fantastically large number, and its square was even larger, this meant that even a tiny amount of matter could release a fabulous amount of energy. A few teaspoons of matter, for example, has the energy of several hydrogen bombs. In fact, a piece of matter the size of a house might be enough to crack the Earth in half.

    I have worked very hard on a Science website on this topic and would love to get some feed back from the physics science community
    thanks: Don

    Quite alot of the site there. Seems like alot of useful information. The only problem I see is that there is no clear goal or objective. Just information being thrown at you. If somehow maybe you could create a better navigation system and have things on a couple different pages instead of all on one page so I can see the bigger picture to where you're going.

    After I clicked on the what, when, where, I kind of got lost. It links to some yahoo search result?

    take a gun loaded with a uranium bullet and shoot a brick of plutonium, see what happens.
