How Scientists Can Slow Down Time

If the prospect of old age frightens you, then maybe you should consider piloting aircraft for a living. The connection might not seem so obvious at first, but according to the principle of time dilation, the faster you move, the slower the experience of time relative to your unmoving counterparts. And relative to people on the ground, people flying on airplanes move much faster and must experience the passage of time more slowly. In the ‘70s, this theory was tested using clocks on aircraft, and more recently a German study was able to replicate the experience of time dilation in a lab. Maybe pilots don’t actually stave off old age for good, but the physics behind the principle are nevertheless important to make sure that technologies like GPS satellites work properly.

Do I Only Use 10% of My Brain?

While we might only be realizing a fraction of our potential, this does not mean that we only use 10% of our brains. Our body’s automatic functions (like breathing) or some of our actions that don’t take very much thought at all (like walking) all rely on the brain. We know this because of technological innovations like MRI’s that give us a greater understand of how—and how much—of the brain actively functions, technologies that have only become available since long after the advent of this myth. So the next time we are tempted to repeat the old adage, maybe we should instead opt to say what it is we really mean—that we have tremendous untapped potential, regardless of the percentage of our brains that we do or do not use.

The Five Most Beautiful Photographs of Earth According to NASA

The Five Most Beautiful Photographs of Earth According to NASA

Gizmodo (article written by Jesus Diaz) features an interesting photo collection with Landsat satellites’ photos.  These satellites been taking photos of the earth for 40 years. According to NASA, the photos in this article are the most beautiful ones.  We do not have a way to compare them with the millions of photos taken by these satellites, but we can vouch that they look amazing, and can even go far enough to say that they resemble art paintings.  Do we need any more proof of the beauty of nature?

The five NASA photos on this site are accompanied with captions by Ellen Gray.

Udacity

[The site creators] believe university-level education can be both high quality and low cost. Using the economics of the Internet, [they have] connected some of the greatest teachers to hundreds of thousands of students in almost every country on Earth. Udacity was founded by three roboticists who believed much of the educational value of their university classes could be offered online for very low cost. A few weeks later, over 160,000 students in more than 190 countries enrolled in our first class, “Introduction to Artificial Intelligence.” The class was twice profiled by the New York Times and also by other news media. Now [they]’re a growing team of educators and engineers, on a mission to change the future of education.

It was interesting to read how Stanford University professor of computer science, Sebastian Thrun decided to open his “Introduction to Artificial Intelligence” class to everyone by offering it online.  The class attracted 160,000 students, and recently professor Thrun announced that he would be giving up his academic position at Stanford devoting more time to his project.

Udacity’s YouTube channel contains several videos on the subjects they offer: http://www.youtube.com/user/Udacity

Would you like to follow a Harvard University Course Online? How about a MIT course?  Sounds interesting?  What if the two prestigious educational institutions got together and offered online courses?

Launched just a couple of days ago, on May 2, 2012, EdX is a joint partnership between The Massachusetts Institute of Technology (MIT) and Harvard University to offer online learning to millions of people around the world. EdX will offer Harvard and MIT classes online for free. Through this partnership, the institutions aim to extend their collective reach to build a global community of online learners and to improve education for everyone.   Along with offering online courses, the institutions will use edX to research how students learn and how technology can facilitate teaching—both on-campus and online.

EdX is based on MITx, a technological platform from MIT designed to offer online versions of their courses. These versions include: video lessons, embedded testing, real-time feedback, student-ranked questions and answers, collaborative web-based laboratories, and student paced learning. Though this will never replace the traditional residential model of undergraduate education, it will serve to improve and supplement the teaching and learning experienced at both universities. In turn, Harvard and MIT have created edX open-source software and invite interested institutions to join edX with their own educational content.

Next week we will feature another online course from a prestigious U.S. University.

Watch the video below with MIT Professor of Electrical Engineering and Computer Science, the first President of edX, Anant Agarwal, introduce the project along with MIT President Susan Hockfield and Harvard University President Drew Faust, accompanied by top officials from both institutions:
