[edit] BMO Round 1

The first round of the BMO is held in December, and from 2006 is an open entry competition, costing £22 to enter. However, this fee is waived for those who (1) achieve the qualifying mark in the Senior Mathematical Challenge and (2) have a British passport, or have studied for 3 years full time education in the UK. The paper lasts 3½ hours, and consists of six questions (from 2005), each worth 10 marks.

Candidates are encouraged to write full proofs to the questions they attempt, as a full answer to a question is worth many more marks than incomplete answers to several questions. This is because of the marking scheme: an answer is marked on either a “0+” or a “10-” mark scheme, depending on whether the answer looks generally complete or not. So if an answer is judged incomplete or unfinished, it is awarded a few marks for progress and relevant observations, whereas if it is presented as complete and correct, marks are deducted for faults, poor reasoning, or unproven assumptions. As a result, it is quite uncommon for an answer to score a middling mark (e.g. 4–6). Continue reading

Already saw ‘Avatar’? You won’t have to wait long for Hollywood to deliver the next big blockbuster smash.

That should come as early as March, with the release of Tim Burton’s deliciously weird take on ‘Alice in Wonderland’ starring Johnny Depp. Until then we have potential hits like the family adventure ‘Percy Jackson,’ the star-studded rom-com ‘Valentine’s Day’ and the Martin Scorsese-directed thriller ‘Shutter Island.’

Then of course there’s the blockbuster hotbed that is summer, with highly anticipated sequels to ‘Iron Man,’ ‘Shrek,’ ‘Sex and the City,’ ‘Toy Story’ and ‘Twilight.’

Excited yet? We look at the 50 biggest movies of 2010.


The Sure Things


‘Alice in Wonderland’
Release Date: March 5
Starring: Johnny Depp, Mia Wasikowska, Helena Bonham Carter
Why It’ll Be Big: Tim Burton’s take on this beloved tale takes place when Alice (Wasikowska) is a teenager, meaning we’ll get a whole new twisty adventure — hosted of course by the wonderfully weird Mad Hatter (Depp as a Madonna lookalike?).

The 25 Best Action Movies

They don’t call ’em motion pictures for nothing. At its heart, film is about motion, forward movement, momentum, unfolding spectacle. In a word, action.

There’s no medium like the movies for telling stories that are about the pure joy of movement, the heart-pounding excitement of grand events taking place before your eyes, the thrill of witnessing brave and foolhardy deeds you’d never attempt in real life. No wonder action films are a beloved movie genre. And these are 25 of our favorites.

(Note: While the overlap with action-oriented subgenres like fantasy, sci-fi and superhero mandated their inclusion here, we did not include Westerns or war films.)
