Circular Periodic Table of the Elements

Mohd Abubakr has redrawn the classic periodic table in a circular pattern to improve the proximity and relationships between the elements.

So why change it? According to Mohd Abubakr from Microsoft Research in Hyderabad, the table can be improved by arranging it in circular form. He says this gives a sense of the relative size of atoms--the closer to the centre, the smaller they are--something that is missing from the current form of the table. It preserves the periods and groups that make Mendeleev's table so useful. And by placing hydrogen and helium near the centre, Abubakr says this solves the problem of whether to put hydrogen with the halogens or alkali metals and of whether to put helium in the 2nd group or with the inert gases.

The strongest feedback about the new circular table is that you have to rotate it to read it.  Kind of a problem when you print a poster and post it in a classroom or a laboratory.  Although I think it's an easy thing to remedy by changing the orientation of the text.

The Elegant Universe

Following my earlier post on Imagining the Tenth Dimension, I found that NOVA has put the entire 3-hour show The Elegant Universe on their website.

The show is full of different visual methods to visual strings, gravity, the scale of particles and multiple dimensions. Brian Greene really did a fantastic job with this show based on his book on the same name.

Hydrogen Atom

phrenopolis.com

Cool website that visualizes a hydrogen atom, showing how much empty space makes up our universe.

The page is scaled so that the smallest thing on it, the electron, is one pixel. That makes the proton, this big ball right next to us, a thousand pixels across, and the distance between them is... yep, fifty million pixels

If your monitor displays 72 pixels to the inch, then that works out to eleven miles - making this possibly the biggest page you've ever seen.
