HP announced in April 2008 that they had developed a switching memristor. This is supposedly an electronic device that falls under the fourth, previously unknown and now debated, fundamental circuit element. In 1971 a link between charge and flux was missing from the four fundamental electromagnetic quantities (charge, voltage, current, and magnetic flux), and the element that linked them was named “memristor”, but was not developed.
It is an interesting technology due to the fact that it could create non-volitile memory that is both cheap and many can fit in a tiny space. Part of the discovery is due to the new capabilities with regard to nano-technology. The uses are not fully known, but it might never see the light of day due to the domination of the transistor and other non-volatile memory that already exists.
Basically a memristor is fundamental a charge-dependent resistance element. This means that the magnetic flux over the element is a function of the amount of charge that has passed through it, simply changes resistance as it is “(dis)charged”. However, don’t take my word for it, as I understand the subject, but have done no research. Instead take a look at some other reports:
A video from TED showing new ways to think about, and experience music.
Tod Machover of MIT’s Media Lab invented the musical technology behind Guitar Hero, and at TED2008 he talks about what’s coming next. Listen for some brand-new ways to interface with music — to play it, compose it, enjoy it. Machover then introduces Dan Ellsey, a composer with cerebral palsy who uses the lab’s tools to write and perform his own music. Ellsey conducts his “My Eagle Song,” in a soaring performance that underscores music’s power to give you chills.
I noticed some new Vox blog designs for the site themes, I chose a football one right now, since the season is just getting underway! Go Vikings! Go Broncos! I also noticed when watching the games that the networks are applying new technology to help make the game easier to understand and give you more information at the same time. There is an article I found on NBC’s new techniques, and they seem to be helping to innovate the field of sports television enhancement technologies [read more]. I also saw one of the networks using a path line similar to the line of scrimmage and the first down line. This path line actually shows where a player ran the ball during a replay. It’s not a huge enhancement, but it actually makes watching the replay a little more interesting. If these enhancements are something that make the game more fun to watch and allow more people to learn about the game, then I’m all for them.
