hi all i just read that surface tension floats a ferry boat like the same way a pin can be placed very carefully on the surface of water, is this true, i always thought that if the boat displaced less water than it could hold it would float, i know there is huge holes in my logic but bare with me I am just a metal fabricator with lots of questions ,so its safe to say that if i put more weight than the weight of water the boat displaces it will sink ,thats logical isn't it providing the boat is made of something the same weight of the water it is floating in... can someone tell me in laymans terms what is e=mc2 because I am really interested in physics but I am having trouble understanding this and i know its a biggie, thanks in advance,john
