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.

How Old is the Universe? [by David A. Weintraub]

David A. Weintraub is professor of astronomy, director of the Communication of Science & Technology program, and director of Undergraduate Studies for Department of Physics & Astronomy at Vanderbilt University.

The title question about the age of our universe poses a deceptively simple question, and its answer carries profound implications for science, religion and philosophy. In this class, we will trace the centuries-old quest by astronomers to fathom the secrets of the nighttime sky. We will discover how they have used their knowledge of astrophysics and their observations of the heavens to determine that the universe is 13.7 billion years old.


By the end of the course, you will understand why astronomers know this is the answer to the title question. Individual classes will focus on


  1. ancient answers for the age of the universe, Renaissance science's impact on that ancient wisdom, and Biblical Chronology as a reasonable seventeenth century response to the birth of modern science;
  2. nineteenth-century discoveries that changed astronomy into astrophysics;
  3. white dwarf stars as a chronometer for the age of the universe;
  4. star clusters as another tool for measuring the age of the universe;
  5. the expanding universe as a third method for dating the universe;
  6. maps of the cosmic background radiation, dark matter and dark energy as a fourth method for determining the age of the universe.


No background in math, astronomy, or physics is required to understand this material.Watch video of Vanderbilt Professor David A. Weintraub speaking March 23 on "How Old is the Universe?" as part of the Osher Lifelong Learning Institute.

Michio Kaku on Singularity 1 on 1: Science is the Engine of Prosperity!

Michio Kaku on Singularity 1 on 1: Science is the Engine of Prosperity! | Science-Videos | Scoop.it

Dr. Michio Kaku is a theoretical physicist, bestselling author, acclaimed public speaker, renowned futurist, and popularizer of science. As co-founder of String Field Theory, Dr. Kaku carries on Einstein's quest to unite the four fundamental forces of nature into a single grand unified theory of everything. You will not be surprised to hear that Michio Kaku has been on my guest dream-list since I started Singularity 1 on 1, and I was beyond ecstatic to finally have an opportunity to speak to him.

During our 90 min conversation with Dr. Michio Kaku we cover a variety of interesting topics such as: why he shifted his focus from the universe to the human mind; his definition, classification and ranking of consciousness; his take on the Penrose-Hameroff Orch OR model; Newton, Einstein, determinism and free will; whether the brain is a classical computer or not; Norman Doidge's work on neuro-plasticity and The Brain That Changes Itself; the underlying reality of everything; his dream to finish what Einstein has started and know the mind of God; The Future of the Mind; mind-uploading and space travel at the speed of light; Moore's Law and D-Wave's quantum computer; the Human Brain Project and whole brain simulation; alternatives paths to AI and the Turing Test as a way of judging progress; cryonics and what is possible and impossible.

NATURE video: A virtual Universe (MIT)

Can current theories of cosmology explain how the Universe evolved? One way to find out is to plug everything we think we know about the early Universe and how galaxies form into a supercomputer, and see what comes out. In a simulation presented today in Nature1, researchers did just that — and revealed a cosmos that looks rather like our own. The findings lend weight to the standard model of cosmology, but could also help physicists to probe where our models of galaxy formation fall down.


Scientists at MIT have traced 13 billion years of galaxy evolution, from shortly after the Big Bang to the present day. Their simulation, named Illustris, captures both the massive scale of the Universe and the intriguing variety of galaxies -- something previous modelers have struggled to do. It produces a Universe that looks remarkably similar to what we see through our telescopes, giving us greater confidence in our understanding of the Universe, from the laws of physics to our theories about galaxy formation.

Mapping and manipulating the brain at scale - Jeremy Freeman

The behavior of an animal reflects computations across its entire nervous system, involving the coordinated activity of thousands of neurons within and across multiple brain areas. New technologies for imaging the nervous system allow us to monitor neural function at unprecedented scales. But the data sets are quickly outpacing the capabilities of ordinary analytical approaches. They are large (one terabyte or more per hour), complex, and high-dimensional, and we want to understand their structure as it evolves over both space and time.

Cognitive Engineering - Engineering Memories - The Future is Now

Dr. Theodore Berger's research is currently focused primarily on the hippocampus, a neural system essential for learning and memory functions.


Theodore Berger leads a multi-disciplinary collaboration with Drs. Marmarelis, Song, Granacki, Heck, and Liu at the University of Southern California, Dr. Cheung at City University of Hong Kong, Drs. Hampson and Deadwyler at Wake Forest University, and Dr. Gerhardt at the University of Kentucky, that is developing a microchip-based neural prosthesis for the hippocampus, a region of the brain responsible for long-term memory. Damage to the hippocampus is frequently associated with epilepsy, stroke, and dementia (Alzheimer's disease), and is considered to underlie the memory deficits characteristic of these neurological conditions.


The essential goals of Dr. Berger's multi-laboratory effort include: (1) experimental study of neuron and neural network function during memory formation -- how does the hippocampus encode information?, (2) formulation of biologically realistic models of neural system dynamics -- can that encoding process be described mathematically to realize a predictive model of how the hippocampus responds to any event?, (3) microchip implementation of neural system models -- can the mathematical model be realized as a set of electronic circuits to achieve parallel processing, rapid computational speed, and miniaturization?, and (4) creation of conformal neuron-electrode interfaces -- can cytoarchitectonic-appropriate multi-electrode arrays be created to optimize bi-directional communication with the brain? By integrating solutions to these component problems, the team is realizing a biomimetic model of hippocampal nonlinear dynamics that can perform the same function as part of the hippocampus.

NASA: The Quest for Other Worlds Like Earth [HD Video]

NASA: The Quest for Other Worlds Like Earth [HD Video] | Science-Videos | Scoop.it

The centuries-old quest for other worlds like our Earth has been rejuvenated by the intense excitement surrounding the discovery of hundreds of planets orbiting other stars. The challenge now is to find terrestrial planets, especially those in the habitable zone of their stars where liquid water might exist on the surface of the planet. The Kepler mission, which launched in March 2009, is specifically designed to survey our region of the Milky Way galaxy to discover Earth-size and smaller planets in or near the habitable zone and determine the fraction of the hundreds of billions of stars in our galaxy that might have such planets. To date, 61 Kepler planets have been confirmed and more than 2,300 planet candidates have been found. This talk will cover many of Kepler's discoveries, including several planets orbiting two stars, and will try to explain how Kepler's discoveries help define humanity's place in the universe.

How to Make Water Flow Uphill Using the Leidenfrost Effect | Science-Videos | Scoop.it

In this 2013 video by Science Friday, researchers take advantage of the Leidenfrost effect to make droplets of water flow up an incline. The Leidenfrost effect occurs when a liquid is placed on a surface that is significantly hotter than the liquid’s boiling point. A layer of vapor prevents the liquid from touching the surface and thus boiling rapidly away—the vapor also allows the liquid to move across the surface with ease.

▶ Seth Lloyd: Quantum Machine Learning and Big Data Sets

Machine learning algorithms find patterns in big data sets. This talk presents quantum machine learning algorithms that give exponential speed-ups over their best existing classical counterparts. The algorithms work by mapping the data set into a quantum state (big quantum data) that contains the data in quantum superposition. Quantum coherence is then used to reveal patterns in the data. The quantum algorithms scale as the logarithm of the size of the database.


Seth Lloyd visited the Quantum AI Lab at Google LA to give a tech talk on "Quantum Machine Learning." This talk took place on January 29, 2014.

The Illusion of Time

Time. We waste it, save it, kill it, make it. The world runs on it. Yet ask physicists what time actually is, and the answer might shock you: They have no idea. Even more surprising, the deep sense we have of time passing from present to past may be nothing more than an illusion. How can our understanding of something so familiar be so wrong? In search of answers, Brian Greene takes us on the ultimate time-traveling adventure, hurtling 50 years into the future before stepping into a wormhole to travel back to the past. Along the way, he will reveal a new way of thinking about time in which moments past, present, and future—from the reign of T. rex to the birth of your great-great-grandchildren—exist all at once. This journey will bring us all the way back to the Big Bang, where physicists think the ultimate secrets of time may be hidden. You'll never look at your wristwatch the same way again.

Wolfram Research | Stephen Wolfram, PhD, introduces the Wolfram Language in this video and demonstrates how the symbolic programming language enables functional programming, querying of large databases, flexible interactivity, and easy deployment.


Wikipedia | Wolfram Language is a highly general, multi-paradigm programming language developed by Wolfram Research, that serves as the main interfacing language for Wolfram Mathematica.

It is designed with emphasis on symbolic computation, functional programming, and rule-based programming. It is built to represent arbitrary structures and data.


The language is very large, touching on numerous domains, often specialized. For example, it includes built-in functions for generating and running Turing machines, creating graphics and audio, analyzing 3D models, and solving differential equations.


It is planned to be bundled with the system software installed on every Raspberry Pi. Intel Edison also integrates the language, and it is planned to be integrated in the Unity game engine.

Tom Campbell: Virtual Reality: Why It's A Better Model Than String Theory and Holographic Universe

In this fascinating interview, physicist Tom Campbell, formerly with and now a consultant for NASA, discusses the current problems facing the scientific community's search for a Grand Unified Theory of Everything. String theory, holography, zero-point field theory, and other vogue models have failed to produce any significant results other than speculation, conjecture, and contradiction-hampered popular films such as 'What the Bleep Do We Know?' While Campbell doesn't merely criticize these theories, he offers a fresh interpretation of the root of the problem: the Double Slit Experiment.

Campbell also discusses information theory, virtual reality, process fractals, the quantum erasure experiments, video games, and the unavoidably primary role of conscious observers within our reality.

Through what he calls the data base, he also discusses accessing the Larger Consciousness System. Yes, His Big TOE derives a Supreme Being.

Tom has excelled as a working scientist, a professional physicist dedicated to pushing back the frontiers of cutting edge technology, large-system simulation, technology development and integration, and complex system vulnerability and risk analysis.

Michio Kaku - What is time? [BBC videos] | Science-Videos | Scoop.it

Michio Kaku discovers our sense of time passing and the clocks that drive our bodies. He reveals the forces of time that make and destroy us in a lifetime. He journeys to some of the Earth's most spectacular geological sites to look for clues to the extraordinary depths of time at a planetary level. Finally, he takes us on a cosmic journey in search of the beginning (and the end) of time itself.


Part 1: Daytime
Time seems to drive every moment. It's the most inescapable force we feel. But do we experience time from within our minds and bodies or from the outside?


Part 2: Lifetime
The most powerful effect of time on our lives is the way it limits us. Our knowledge of death is so embedded in our lives and spirituality that, were immortality possible, would we lose the sense that makes us human?


Part 3: Earthtime
The most powerful effect of time on our lives is the way it limits us. Our knowledge of death is so embedded in our lives and spirituality that, were immortality possible, would we lose the sense that makes us human?


Part 4: Cosmic Time
We've always structured our lives based on an unchanging past and a predictable and ordered future. But atomic and cosmic discoveries have changed all that. What is time itself? And will it ever end?
