Scanning thermal camera The DIY thermographer is a camera which creates an image of what temperature things are -- a 'heat' camera. This approach has been put on hold in favor of the "thermal flashlight" technique which is now posted on the main Thermal Camera tool page We're making a 'scanning thermal imager' which means we just use a temperature sensor and sweep it back and forth across a scene, recording the temperature variation to build up an image that looks like this: There are two main parts to the project: the camera itself (currently made of Legos and an Arduino, and the website, thermographer.publiclaboratory.org, which helps you create an image from your recorded temperatures.
Wormhole A wormhole, also known as an Einstein–Rosen bridge, is a hypothetical topological feature of spacetime that would fundamentally be a "shortcut" through spacetime. A wormhole is much like a tunnel with two ends each in separate points in spacetime. For a simplified notion of a wormhole, visualize space as a two-dimensional (2D) surface. Create your own vocabulary tests Developing your vocabulary is one of the quickest ways of improving your English, but remembering new vocabulary can take time and effort. In this task you find out how to use an online dictionary to find synonyms and antonyms and how to use this to create your own interactive tests to help you remember the words. Task: Find an article that you are interested in or that you have recently studied.
Web 2.0 List Here is a list of web 2.0 tools and other educational technology tools that I have previewed and many of them used in the classroom. Eventually I will do a tutorial and highlight most of these but in the meantime for those who are up to just exploring and figuring them out yourselves, then have at it and enjoy.

Sign Up Course Description New Wormhole Theory Uses Space Photon Energy “Fluid” A new theory expands on other theories and adds photon energy “fluid” as a way to support wormholes. The introduction to the paper states the following. Wormholes are hypothetical geometrical structures connecting two universes or two distant parts of the same universe. For a simple visual explanation of a wormhole, consider spacetime visualized as a two-dimensional (2D) surface. If this surface is folded along a third dimension, it allows one to picture a wormhole “bridge”.  “A possible cause of the late-time cosmic acceleration is an exotic ﬂuid with an equation of state lying within the phantom regime, i.e., w = p/ρ < −1.

50 Education Technology Tools Every Teacher Should Know About Technology and education are pretty intertwined these days and nearly every teacher has a few favorite tech tools that make doing his or her job and connecting with students a little bit easier and more fun for all involved. Yet as with anything related to technology, new tools are hitting the market constantly and older ones rising to prominence, broadening their scope, or just adding new features that make them better matches for education, which can make it hard to keep up with the newest and most useful tools even for the most tech-savvy teachers. Here, we’ve compiled a list of some of the tech tools, including some that are becoming increasingly popular and widely used, that should be part of any teacher’s tech tool arsenal this year, whether for their own personal use or as educational aids in the classroom.

New data confirms: Neutrinos are still traveling faster than light "It is worth pointing out, however, that the latest arXiv preprint lists 179 authors, while the original lists 174. Would you ever classify five people as "most of" 15? To make things more confusing . . . "four new people" have decided not to sign, according to Science. Now, none of the above numbers may match up . . .." The original 174 include a duplicate " F.
