    Facts about Euler

    from the Facebook group "We fully acknowledge the True Ultimate Ass-Kicking Power of Leonhard Euler": Leonhard Euler is well known for being the most kick-ass mathematician in recorded history. By 'kick-ass' I don't mean he was the greatest mathematician - we all know that was Gauss - but...

    Infinite Product q

    What is the limit (if any) of the infinite product (1-1/2)(1-1/4)(1-1/8)(1-1/16)(1-1/32)...(1-2^(-n)) as n-->oo ? It seems to hover around 0.28888, but it might also approach 0 extremely slowly.

    Actuarial cutoffs

    is it coincidence or what that the cutoffs for actuarial studies at UNSW and Macq are exactly the same this year? The BCom at UNSW went up from 93 last yr to 95.10 and the BCom (Actuarial) went down from 96 to 95.10.

    combinatorics/probability problem

    I have a problem that I've been thinking about. It seems to quite ubiquitious and generic. I have n pigeonholes and a large number of letters. There are 2 parts to this q: 1. I take n letters and randomly put each of them in a pigeonhole. On average, what fraction of the n pigeonholes will...

    How interesting is Information Systems?

    Originally, I was really into computing and wanted to do combined BCom/BSci - Actuarial + Computer Sci, but now I'm limited to just a single degree- BCom with actuarial. i wanna know if IS has a lot of low level programming and maths which is what i'm really into or if it's just lots of...

    Highest UAI WITHOUT getting a Premier's Award

    I was just wondering who would be the unluckiest as to have the highest UAI but without getting 90%+ in 10 units or more i.e. you can't have more than 9 units of 90%+ :P in order to qualify for this i missed out by 1 mark in english and expecting a UAI around 99... will confirm later when...

    Special Relativity Time Dilation Q

    from 2003 HSC Physics q5 An astronaut set out in a spaceship from Earth orbit to travel to a distant star in our galaxy. The spaceship travelled at a speed of 0.8 c. When the spaceship reached the star the on-board clock showed the astronaut that the journey took 10 years. An identical clock...

    Heisenberg Uncertainty Principle

    Why do so many textbooks confuse the Heisenberg Uncertainty Principle with the observer effect? The uncertainty principle in quantum mechanics is sometimes erroneously explained by claiming that the measurement of position necessarily disturbs a particle's momentum eg by using a high frequency...

    Converse of Galilean/Newtonian Principle of Relativity

    THe Principle of Relativity says that if something is moving in an inertial frame of reference (constant velocity) then it is impossible to determine its velocity without reference to an outside point i.e. an astronaut in a spaceship moving at constant velocity has no way of telling if he is...

    Relativistic Paradox

    A charged particle, say an electron, moving through an external magnetic field is deflected perpendicularly to the direction of the magnetic field and the direction of tis velocity (right hand push rule) because a moving charged particle induces a magnetic field which interacts with the external...
