Group Theory 4: Symmetries
2008-05-29 08:37:00 In the previous instalment we saw some very "mathematical" examples of groups, but group theory also has an important geometrical aspect. We'll take a look at that before we get into the more abstract material of group theory proper.

Group Theory 3: Some Groups from Arithmetic
2008-05-09 22:24:00 Now we have the formal definition of a group, we'll look at some first examples and reveal their group structure. This will offer good practice in using the definition, so ideally you should read each example and try to prove for yourself that it has the required properties before moving on.

Group Theory 2: Definitions
2008-04-30 08:42:00 OK, for many readers this is probably the painful part of any of our posts about mathematical subjects but it can’t be avoided: the definitions. The spirit of this mini-series is fairly informal, but we need to get a sense of what a group is before we can get anywhere at all.

How to balance a portfolio with magic of maths
2008-04-14 14:28:00 Everybody in the investing world probably heard the must requirement of portfolio balancing depends on your age. Balancing your portfolio between equity and debt investment instruments entirely depends on the Golden Investment Balancing Rule, “Reducing your age from 100 and have the resulted percentage in equity and rest in debt instruments”. For example, if your age is 25. Subtracting 25 from 100 will give you 75. In your case, your portfolio should have 75% of equity exposure and 25% in debt instruments. I agree.But there is a hidden and difficult part if you look deep inside to this balancing formula. Before saying the same, you should know what the exact result the rule makers intend to give by this rule.By this rule, someone should balance there portfolio properly from the younger age when he starts investments with maximum equity and minimum debt exposure. But, when he reaches to the age of retirement, his portfolio should have maximum debt and minimum equity exposure.Here...

ITV commentators and their inability to do simple maths
2007-11-29 15:20:00 One thing that infuriates me when watching a match is when the commentator or analyst starts to spout complete garbage that it so blatently wrong that you wonder how no-one is shutting them up. Repeating these idiocies over and over often makes me reach for the mute button. Take Tuesday night's game. Throughout the second half, we heard repeatedly, 'If Sevilla win this game, Arsenal can only win the group if Sevilla lose their final match'. No. If Sevilla draw, and Arsenal win, Arsenal win the group. It's not that hard to work out, given that in that circumstance, both teams would've achieved exactly the same results in their games, Arsenal winning the head to head battle on goal difference. But over and over again they insisted that a draw would be good enough for Sevilla, which it quite blatently wouldn't. It got even worse elsewhere. Rangers began the night one point ahead of Lyon, but having won 3-0 in France the Scots held the head to head advantage. Throughout the n...
