A Taxonomy of Visualization Techniques

MMatessa Re:ManyEyes by IBM (26 comments)

Article types
Data & View Specification: Visualize data by choosing visual encodings. Filter out data to focus on relevant Items. Sort Items to expose patterns. Derive values or models from source data.
View Manipulation: Select items to highlight, filter, or manipulate them. Navigate to examine high-level patterns and low-level detail. Coordinate views for linked, multi-dimensional exploration. Organize multiple windows and workspaces.
Process & Provenance: Record analysis histories for revisitation,, review and sharing. Annotate patterns to document findings. Share views and annotations to enable collaboration. Guide users through analysis tasks or stories.


Many Eyes types
See relationships among data points: Scatterplot. Matrix Chart. Network Diagram.
Compare a set of values: Bar Chart. Block Histogram. Bubble Chart. Track rises and falls over time: Line Graph. Stack Graph. Stack Graph for Categories.
See the parts of a whole: Pie Chart. Treemap. Treemap for Comparisons.
Analyze a text: Word Tree. Tag Cloud. Phrase Net. Word Cloud Generator.
See the world: Ottawa Neighbourhood Map. US County Map. World Map. Massachusetts Map. New Jersey Map.

The logical pattern is easier to see in this search table. The most frequent English letters are higher in the table.

Airline Pilots Allowed To Dodge Security Screening

MMatessa Pittsburgh! (285 comments)

Pittsburgh is one of the few American cities to be spelled with an h at the end of a burg suffix. While briefly named "Pittsburg" from 1890 to 1911 following a declaration by the United States Board on Geographic Names, the "Pittsburgh" spelling was officially restored after a public campaign by the citizens of the city.

Atlantis Lands, Ending the Shuttle Era

MMatessa Re:Return to Space? (256 comments)

How many active space exploration missions are there? One or two? Over a dozen. Studying Mercury, Mars, Saturn, Vesta, and on the way to Pluto.
Here's a map of them all.

MMatessa Re:Reasoned Debate? (307 comments)

How about structuring comments by topic instead of by time? Some MIT folks have used argument mapping to structure debates on climate change at Climate CoLab

How To Deflect an Asteroid With Today's Technology

MMatessa Re:It all depends on detection... (264 comments)

I've been looking for a way to get into cheap astrophotograpy and found some people using webcams to detect stars down to magnitude 9.6 and even magnitude 14.5. Has anyone else found links to more recent work?

Mystery company may be an asteroid mining project

MMatessa MMatessa writes  |  more than 2 years ago

MMatessa (673870) writes "From The Verge: MIT's Technology Review has just gotten news of a mysterious new project that claims it will "create a new industry and a new definition of 'natural resources.'" Space exploration company Planetary Resources will be unveiled in a conference call on Tuesday, April 24th. Besides the audacious announcement, which promises to "overlay two critical sectors — space exploration and natural resources — to add trillions of dollars to the global GDP," what makes this unique is its high-profile support group. The venture is backed by Google executives Larry Page and Eric Schmidt, director James Cameron, and politician Ross Perot's son, among others."

Liquid metal batteries may be the solution to renewable energy

MMatessa MMatessa writes  |  more than 2 years ago

MMatessa (673870) writes "What's the key to using alternative energy, like solar and wind? Storage — so we can have power on tap even when the sun's not out and the wind's not blowing. In this talk, Donald Sadoway takes to the blackboard to show us the future of large-scale batteries that store renewable energy. As he says: "We need to think about the problem differently. We need to think big. We need to think cheap.""

Does the Sun influence radioactive decay on Earth?

MMatessa MMatessa writes  |  more than 4 years ago

MMatessa (673870) writes "When researchers found an unusual linkage between solar flares and the inner life of radioactive elements on Earth, it touched off a scientific detective investigation that could end up protecting the lives of space-walking astronauts and maybe rewriting some of the assumptions of physics. Researchers from Stanford and Purdue University have found decay rates showing a seasonal variation, dropping during solar a flare, and having 33 day patterns."

Etoys Programming Environment Helps Kids to Learn

MMatessa MMatessa writes  |  more than 6 years ago

MMatessa writes "Alan Kay's recent TED talk shows how the new teaching software called Etoys can help kids to learn. As described in this pdf document, Etoys is like LOGO (object-oriented scripts), like Hypercard (WYSIWYG UI), like Starlogo (massively parallel objects), and like Squeak Smalltalk (everything a dynamic object). Etoys can run on Linux, Mac, and Windows, and is included in the One Laptop Per Child XO laptops."

Thorium Reactors Better Than Uranium Reactors?

MMatessa MMatessa writes  |  more than 6 years ago

MMatessa writes "Radical new technology based on thorium could potentially alleviate three of the most pressing issues facing modern civilization in the 21st century: the hunger for energy, the spectre of climate change and the need to eliminate nuclear weapons. The main stumbling block of using thorium reactors until now has been how to provide thorium fuel with enough neutrons to keep the reaction going, and do so in an efficient and economical way.

In recent years two new technologies have been developed to do just this. The Thorium Power company is developing a way to modify existing nuclear plants to use mixed fuels consisting of enriched uranium, plutonium, and thorium. And Carlos Rubbia is designing a method that uses a particle accelerator fired at a lead target to release neutrons that collide with nuclei in the thorium fuel."

New solar energy collector works at night

MMatessa MMatessa writes  |  more than 6 years ago

MMatessa (673870) writes "Researchers at Idaho National Laboratory are developing a novel way to collect energy from the sun with a technology that could potentially cost pennies a yard, be imprinted on flexible materials and still draw energy after the sun has set. The new approach uses a special manufacturing process to stamp tiny square spirals of conducting metal onto a sheet of plastic. Each interlocking spiral "nanoantenna" is as wide as 1/25 the diameter of a human hair."
