    Graduate The Proof: There exist interval [A,B] that cannot have a sub-interval

    the proof shows this is not the case "its counter-intuitive ofcourse, but math does not care as we know" in a nutshell, the proof shows one important notion: " when you accept the premise that says: Every interval has a proper sub-interval, when you accept this as true, this leads to the...

    Graduate The Proof: There exist interval [A,B] that cannot have a sub-interval

    This is a proof that: There exist interval [A,B] on the real numbers line that is indivisible as a mathematical point is indivisible. ------------------------------ Its a proof by contradiction, starting with premise 1 Proof \aleph L represents the cardinality of all possible...

    Graduate Is the work on Fermat's Theorem really done?

    about Wiles proof, there is a real problem about it: its too complicated to be verified by most mathematicians. in other words, its believed that only few people in the world can investigate it. I am sure Wiles is a great mathematician with good intentions,, but when something is too complex...

    Undergrad Does Helium Expands Faster than Air When Heated?

    thank you for your reply ,, but based on what you have concluded that Helium will absorb energy faster than air? Note: yes, faster means: higher chanage in volume per unit time thanks

    Undergrad Does Helium Expands Faster than Air When Heated?

    This is a really confusing issue .. even when asked my professor in thermodynamics he tried to derive many theromdynamic equations and could not come to a conclusion about it if we have two cylinder piston systems ,, they both have the exact same conditions except the kind of gas in each one...
