Michio Kaku: Can Nanotechnology Create Utopia?

Dr. Kaku addresses the question of the possibility of utopia, the perfect society that people have tried to create throughout history. These dreams have not been realized because we have scarcity. However, now we have nanotechnology, and with nanotechnology, perhaps, says Dr. Michio Kaku, maybe in 100 years, we'll have something called the replicator, which will create enormous abundance.

95 Video Lectures on Nanoelectronic Modeling

The goal of this series of lectures is to explain the critical concepts in the understanding of the state-of-the-art modeling of nanoelectronic devices such as resonant tunneling diodes, quantum wells, quantum dots, nanowires, and ultra-scaled transistors. Three fundamental concepts critical to the understanding of nanoelectronic devices will be explored: 1) open systems vs. closed systems, 2) non-equilibrium systems vs. close-to-equilibrium systems, and 3) atomistic material representation vs. continuum matter representation.

Big Thinking: The Power of Nanoscience [VIDEO]

Berkeley Lab scientists reveal how nanoscience will bring us cleaner energy, faster computers, and improved medicine.

 

Alex Weber-Bargioni: How can we see things at the nanoscale? Alex is pioneering new methods that provide unprecedented insight into nanoscale materials and molecular interactions. The goal is to create rules for building nanoscale materials.

 

Babak Sanii: Nature is an expert at making nanoscale devices such as proteins. Babak is developing ways to see these biological widgets, which could help scientists develop synthetic devices that mimic the best that nature has to offer.

 

Ting Xu: How are we going to make nanoscale devices? A future in which materials and devices are able to assemble themselves may not be that far down the road. Ting is finding ways to induce a wide range of nanoscopic building blocks to assemble into complex structures.

The strange new world of Nanoscience – Narrated by Stephen Fry

The strange new world of Nanoscience – Narrated by Stephen Fry | Science-Videos | Scoop.it
Where and what is nano? How will it shape our future? Nanoscience is the study of phenomena and manipulation of materials at the nanoscale, where properties differ significantly from those at a larger scale. The strange world of nanoscience – it can take you into atoms and beyond the stars.

von Neumann probes, Dyson spheres, exploratory engineering and the Fermi paradox

Fermi paradox: Our universe is fairly old - where are all the aliens? 

 

The Fermi paradox is the contrast between the high estimate of the likelihood of extraterritorial civilizations, and the lack of visible evidence of them. But what sort of evidence should we expect to see? This is what exploratory engineering can tell us, giving us estimates of what kind of cosmic structures are plausibly constructable by advanced civilizations, and what traces they would leave. Based on our current knowledge, it seems that it would be easy for such a civilization to rapidly occupy vast swathes of the universe in a visible fashion. There are game-theoretic reasons to suppose that they would do so. This leads to a worsening of the Fermi paradox, reducing the likelihood of "advanced but unseen" civilizations, even in other galaxies.
