Sophie Wilson – The future of microprocessors

In this 2014 talk, one of the designers of the original ARM processor, Sophie Wilson, gives an overview of the history of processors and what to expect in future.

The presentation covers in layman’s terms topics like Moore’s law (obviously), pipelining, parallelism, power consumption, heat dissipation, processor specialization and cost of production among other things. As explained, all those aspects are facing difficult challenges that are likely to shape the future of microprocessors, which in turns impacts both hardware and software engineers.

Here is the same presentation in 2016:

The physics of cloaking

In this seminar, Dr. Greg Gbur presents the current state of research on cloaking devices, the differences between science fiction and what seem to actually be possible, and different applications beyond invisibility, like protection from thermal radiation or earthquakes.

More schlieren photography

I previously mentioned a video showing how schlieren photography could be used to film the propagation of sound.

This video by the Harvard Natural Science Lecture Demonstrations, presents different experiments with schlieren photography. The complete description of the setup used, as well as the explanation of the effect, is also available on the associated web page.
