Improve your listening skills while watching this very nice video on augmented reality.
The video has been extracted from http://www.campusvirtual.frba.utn.edu.ar/homogeneo/. That's the UTN.BA virtual classroom!. I suggest you have a look at it. It's really cool! And, by the way, it's not only English that is taught, but several other subjects as well (Sistemas de representación, Ingeniería y sociedad, among others).
The article we’re going to read is: American Composites Manufacturers Association (ACMA). “Definition of FRP”
Here’s the lesson … Sigue leyendo
Eythor Bender of Berkeley Bionics brings onstage two amazing exoskeletons, HULC (Human Universal Load Carrier) and eLEGS — robotic add-ons that could one day allow a human to carry 200 pounds without tiring, or allow a wheelchair user to stand and walk. It’s a powerful onstage demo, with implications for human potential of all kinds.
The video lecture you’re going to watch (cf link below) was recorded on the MIT campus. The lecturer – Prof. Lewin - is well known at MIT and beyond for his dynamic and engaging lecture style.
This is the last part of a first-semester freshman  physics class. Professor Lewin explains and gives a demonstration about the conservation of Mechanical Energy: A wrecking ball is converting gravitational potential energy into kinetic energy and back and forth. If released with zero speed, the wrecking ball should NOT swing higher than its height when it was released. Professor Lewin puts his life on the line by demonstrating this.
If you have already attended Physics I – in Spanish, of course – , I bet you can easily follow the explanation, even though you don’t catch every single word. Am I right? So, what does it mean?
BEFORE YOU WATCH —> VOCABULARY WORK:
Before you embark on the watching activity, recall what you’ve learnt about the conservation of energy, and check these words in English so as to get familiar with the topic (You’re supposed to be familiar with it already, though):
Gravitational potential energy
A wrecking ball / wrecker ball:
Try to take advantage of your knowledge of Physics (1st year) to help you understand what the lecturer explains.
In class, several activities were done on this. (fill-in-the-blanks task, answer questions, translate into or explain in Spanish, …)
