Logical magnets

Jeri Ellsworth has made a great video in which she explains magnetic hysteresis, and how magnetic properties can be used for magnetic storage and logic.

She fairly describes magnetic logic as a forgotten technology, but I wonder if people are looking at this again since for high end electronics since we now have not only magnetic recording media, but also magnetoresistive random-access memory.

I should get paid more…

According to Oxford University their graduate students in materials are the best paid in the whole University…. surely that means I should be getting paid more…

Oxford Graduate Wages

Oxford Leavers Graduate Wages

The Times Higher Education magazine (THE) magazine recently highlighted Oxford’s published data from the survey of Destinations of Leavers from Higher Education. From the 2009 and 2010 data comparing graduate salaries six months after leaving Oxford, the department is very pleased to see that Materials graduates have the highest average earnings.

Sequences game

I made a new game for by website at http://mathewpeet.org/, you can play [here].

In the game you have to say what is missing from the sequence presented to you.

I will be grateful for any suggestions for sequences I can add.

View crystal structures

There is a very nice java package which lets you view crystal structures on any computer platform that supports java (Linux, Mac, etc).

Jmol can be downloaded from sourceforge here. Download the latest binary or full package, unpack it and you are good to go.

Either cd into the directory and run ./jmol or add the directory to your $PATH environment and run jmol.

some molecule

I have a feeling I have referred to Jmol in a previous post but I think I’d only used it as an applet then.

The full version alloys export of the images to graphics formats, as well as lots of options that I don’t understand. You can view molecules in 3D if you have the proper pair of glasses, and you can load crystal structures in the xyz format from sites such as Crystal Lattice*Structures at the U.S. naval research laboratory (note this is very different to navel research). I’m particularly impressed by the ability to change the background colour to white, which is particularly useful if you ever want to print something.
