    Vacuum: Potential Energy & Universe Expansion?

    Okay. Thanks for the discussion. What I get from this discussion is that although a vacuum does not store energy, but does have the potential to kind of absorb energy while the energy is applied by another mechanism. Anyway, let's consider another scenario. A man is holding a group of...

    Vacuum: Potential Energy & Universe Expansion?

    No, no did not mean energy in the sense of term energy used in physics. I mean inducing vacuum in a tube produces a capacity to do work, i.e., air rushing into fill the tube when this vacuum tube is opened, hence causing displacement of air. I meant to ask if a vacuum tube can be considered a...

    Vacuum: Potential Energy & Universe Expansion?

    If I induce vacuum in a glass tube and then I open the lid of the glass tube, air rushes into fill in the vacuum. Can vacuum be regarded as a sort of potential energy, able to exert a force? Can a vacuum tube be considered as a potential storage device for energy, just like a container filled...

    Who are the Top Mathematicians of All Time?

    Quite interestingly, I do not find the name of Al Khwarzimi, the father of Algebra, and not even Aryabhata in above-mentioned list. Modern mathematics would cease to exist without algebra and the concept of zero.
