A look at 2012’s scientific achievements

In the latest issue of the New Scientist magazine, there is an article that briefly summarizes last year’s discoveries and debates in the physical sciences.  These were:

1- “Beyond Higgs: Deviant decays hint at exotic physics” [read more]

2- “Neutrino speed errors dash exotic physics dreams” [read more]

3- “If you want to be president, hire geeks not pundits” [read more]

4- “Why physicists can’t avoid a creation event” [read more]

5- “Fiendish ‘ABC proof’ heralds new mathematical universe” [read more]

6- “Death-defying time crystal could outlast the universe” [read more]

7- “Truth of the matter: The Majorana particle mystery” [read more]

8- “Quantum measurements leave Schrödinger’s cat alive” [read more]

9- “US judge rules that you can’t copyright pi” [read more]

10- “Move over graphene, silicene is the new star material” [read more]

Learning LaTeX online

I recently had to learn some basics about LaTeX, which is free software used to create professionally typeset documents.  Its strength lies in formatting technical and scientific documents that contain mathematical notations.

Below are links to some short videos that are useful for learning how to use LaTeX:

Mathematical theory and the Rubik’s Cube

The 2012 World Cube Association’s U.S. National Championship was held at the beginning of August in Las Vegas.  A California teenager, Deven Nadudvari, set a record by using one hand to solve 5 different 3-by-3 Rubik’s Cubes in an average of 14.86 seconds each.

“You can use Rubik’s Cube to teach engineering, you can use it to teach mathematics, and you can use it to talk about the interplay between design and engineering and mathematics and creativity,“ according to Paul Hoffman, president of the Liberty Science Center in Jersey City, who is organizing an international exhibition in 2014 that will celebrate the cube’s 40th anniversary. (Montreal Gazette, 8/11/2012, Quenqua)

The Rubik’s Cube has been used to teach Group Theory in mathematics.  For more information about group theory and the cube, check out any of these books.
