Divisible Electrons. Democritus Would Not Be Pleased.

In a one-dimensional (1D) system of interacting electrons, excitations of spin and charge travel at different speeds, according to the theory of a Tomonaga-Luttinger liquid (TLL) at low energies. However, the clear observation of this spin-charge separation is an ongoing challenge experimentally. We have fabricated an electrostatically gated 1D system in which we observe spin-charge separation and also the predicted power-law suppression of tunneling into the 1D system. The spin-charge separation persists even beyond the …

Great Use of Backpack with Pages for Each Day.

“I have a page set up for each day of the workweek, and I evenly distribute the action tasks for all of my marketing tactics throughout the week. On a given day, I simply click on that day’s page and get to work on the tasks, which are within a handy checklist (see image above along the left). Each Monday, I un-check all the lists on every page, which helps me to stay accountable to …

Why Hasn’t Someone Made a FriendFeed Client for GMail like TwitterGadget?

I love TwitterGadget as a fully functioning Twitter client within GMail. Back in the "good old" days of Twitter, we had IM integration so these sorts of tools weren't needed if GMail was a major part of your workflow.  However, Twitter took that functionality (and Track) away from users in May '08, so we've been scrambling around to find the most efficient apps ever since. While I think Seesmic Web has a great deal of …

Great Review of @Posterous

Years of building and maintaining my WordPress blog have resulted in my learning a lot about WordPress and getting a lot of grease under my fingernails. Weeks of using Posterous has resulted in a media-rich blog with several posts per week. Tell me which service is more powerful. via suntimes.com I started using Posterous primarily as a photo-blog back in September of ’08. However, it’s transitioned into my full time personal blog as I’ve changed …

IB Principles and Auto-Stitch

Clearly, I’m in love with the Auto-Stitch iPhone app.  But here’s some progress on one of the white boards in my classroom with pics of scientists who represent the 10 International Baccalaureate ideals… Sent from my iPhone

GMail vs Backpack

Now that I’ve decided on Backpack over Evernote as my hub of workflow (see post below), I’m in love with the Journal feature. As a teacher, it’s going to be a fantastic “private Twitter” that will allow me to record, sort and even subscribe (via the RSS feed and Google Reader) to my insights and daily documentations.  I’m just thinking out loud here, but since I need to record most things on my mobile device …

From Evernote Back to Backpack

I’ve been a longtime Evernote member going back to March ’08 (and then a paying Premium member since June ’08 shortly after they opened that functionality), but I just can’t figure out the best way to integrate the service into my workflow.  I’ve certainly tried because I do see so much potential in the product. However, since I’ve been trying to do most everything using only web apps and my iPhone, I’ve had a tougher …

The Kids Are Alright

Children are unconsciously the most rational beings on earth,” says Alison Gopnik, “brilliantly drawing accurate conclusions from data, performing complex statistical analyses, and doing clever experiments.” And not only does empirical work reveal this about babies and small children, but what is thus revealed throws light on some of philosophy’s more intriguing questions about knowledge, the self, other minds, and the basis of morality. via barnesandnoble.com Beautiful thought-provoking post pertinent for us parents, us teachers …

FriendFeed Catchup in GMail

I absolutely love FriendFeed's GMail IM integration. It's how I consume most of my FriendFeed content as well as lots from my favorite folks on Twitter that I have piped into FF via the Imaginary Friends (now Rooms) feature. So, if I miss a few hours and want to catch up on what is going on in the Valley or from the folks I follow (and left GMail open on my Macbook), I can just …
