Journal 15, Electron computing
The working principles of the device are based on sequential tunneling of single electrons between the phosphorus atom and the source and drain leads of the transistor. The rapid development of computers, which created the present information society, has been mainly based on the reduction of the size of transistors. In the recently developed transistor, all the electric current passes through the same single atom. This allows researchers to study the effects arising in the extreme limit of the transistor size.Problems arising when the size of a transistor is shrunk towards the ultimate limit are due to the emergence of so-called quantum mechanical effects. On one hand, these phenomena are expected to challenge the usual transistor operation. On the other hand, they allow classically irrational behavior which can, in principle, be harnessed for conceptually more efficient computing, quantum computing.The driving force behind the measurements reported now is the idea to utilize the spin degree of freedom of an electron of the phosphorus donor as a quantum bit, a qubit."http://www.sciencedaily.com/releases/2009/12/091206085833.htmhttp://www.news.cornell.edu/releases/June02/McEuen.transistor.deb.html
This is a big leap into the advancement of quantum mechanics. In the subatomic level there are a whole different set of rules of physics compared to our normal world. We could speed up transfer rates of data with the new phosphorous transistor. If only we could get a quantum computer processor out in development we could make data analyzing much faster and access patterns of nature to predict outcomes to save life or make lives more efficient. A quantum computer can do a years worth of data building from the fastest computer know in one hour. Just think if we put that to analyzing traffic patterns or a broadband server.

journal 14, smart armor
Smart armor is being developed by the US Army Tank Automotive Research center in Michigan. Smart armor can detect damage and inform the soldiers what kinds of bullets are being fired. Another feature is it can predict its own failure. When the armor is struck it will send out an electric pulse to the computers to be analyzed. It is like any of the shooting video games where you can see your health decrease as you are getting shot. You can predict when you are about to die or when you need to retreat for armor. Intelligent armor uses piezoelectrics which are materials that generate a small amount of voltage when being bent. They are also reversible so that if you put a current to it they will bend. The material is not new but the sensors are. The sensors are crucial to show how the armor is holding up on the tanks or soldiers body. An electric current flows into one sensor and turns it into mechanical energy in the form of a tiny vibration that ripples through the armor plate. The other piezoelectric device takes that mechanical vibration and turns it back into electrical energy.
This will be a great use to soldiers and tanks when on enemy lines. If you can tell how your armor is holding up and how many more shots you can take before you drop it would give your army an advantage and result in fewer casualties. If a soldier could see that he can’t take but one more shot most likely he is going to retreat to a safe zone for new armor. The other advantage is we can what they are shooting. In a tank I would not see that being such a great advantage but if you are a foot soldier getting shot at it might be necessary. Smart Armor is a great start to creating a way to use defense as offense.

journal 13, Youtube autocaption
One more reason why Google is not an evil company out to rule the world is the unleashing of Youtube.com captioning. It would be hard to enjoy watching youtube.com videos without sound. Google has added the caption features that will allow users to upload videos and add captioning to their videos without a big hassle. Google has a lot of experience with speech recognition such as GOOG-411 free telephone information service for everyone. This would also be a great feature for people who are hearing impaired. This may have been pushed by the vice president of Google because he is also hearing impaired. This will give another reason why the internet is good in schools and to get out of the 19th century books. The service is not perfect yet but it will get better in time if it is put to use and get training.
Google 411 was not perfect when it came out but now I personally use it when I am looking for a restaurant or a local business. Google is using its power minds to get people who would not normally use the internet to explore without coming across frustrating problems. I know that people will use this feature even when they can hear because there are some times when you can’t understand what the person is saying an it might be crucial to the video. I would use this for a math video because I don’t need to hear what the person is saying but just watch how he/she does the problem. I could sit in my math class and have my main instructor going and a youtube.com video working on the same concept so that if I don’t understand one part of the main lecture I am not lost for the rest of the class. Google is using their power and reputation for good in Youtube.com and other products such Chrome OS which has yet to be released!

journal 12 ,LCROSS
On October 9th NASA fired an empty shell warhead followed be a camera loaded trailer toward the moon. It was called LCROSS mission which was to test for water on the moon. How it worked was the empty shell would impact the moon’s surface which would throw up a lot of debris that could be analyzed. This is why NASA sent a 90 second delayed trailing satellite that would capture a good close up image and video of the debris. The satellite would then send the information back to Earth which would an analyzed. There has been a long debate on if there is water on moon. On October 9th the LCROSS mission did in fact uncover water on the moon. The thing that was so cool about this mission is that NASA used the slingshot method to fire the “bullet”. The empty shell was sent up into Earth’s orbit which revolved multiple times over 38 days. As you get further away from the Earth but remain in orbit the faster the object will travel. Once the shell had reached a very fast speed it was ignited out of orbit and slung towards the moon. The crash was so big that an amateur telescope was able to see it from Earth.
One thing about this mission that was really neat was that NASA let the people watch what they were watching by streaming the trailing satellites video on the internet. I got up at 7am to watch it that morning. This would be a great move for NASA if they could involve the public more like they did with the LCROSS mission in future missions. There are people who think that NASA is just a waste of money. I believe that they say this because they don’t get anything out of it. There will be more people backing NASA if they can get the public somewhat involved instead of seeming mysterious and hidden.

Journal 11, Microsoft Security Essentials
I have downloaded Microsoft Security Essentials and I am a fan. I have been a long time user of AVG free edition until the beginning of November. The problem with AVG was that when you get the free version, the scan speed is much slower than the purchased edition. MSE scans very quickly and quietly. The other problem with AVG free was the fact that it would bog down my CPU and make it hot. I think that the reason Microsoft is making this free is that PC has been getting slammed on the amount of virus's compared to Apple computers. If Microsoft can produce a close to virus free PC their sales should rise and boost the users of Windows 7.
