Are you Cryo-Curious? Learn about the real facts of cryonics at the first Cryonics Symposium International.

The mission of Cryonics Symposium International is to bring leaders in the cryonics community together to learn from each other and promote the emerging science of cryonics.

With master-of-ceremonies Rudi Hoffman, the first time ever assembly of luminaries from different cryonics organizations will be presenting on the concepts behind the science and research of cryonics at the Church of Perpetual Life in Hollywood, Florida on Saturday, July 27th from 10 AM — 5 PM. The Church is located at 1855 McKinley St, Hollywood, FL 33021. This historic event is free-of-charge: donations are graciously accepted. Attendees will enjoy complimentary meals for the duration of the event. Seats are limited. RSVP is required via Eventbrite https://www.eventbrite.com/e/cryonics-symposium-internationa…———-

In the last video in this series, we started on a quest to clear up the misconceptions between artificial intelligence and machine learning, beginning with discussing supervised learning, an essential foundational building block in understanding the modern field of machine learning.

The focus of this video then will continue right were the last one left off, so sit back, relax and join me once again in an exploration into the field of machine learning — more specifically, unsupervised learning!

Thank you to the patron(s) who supported this video ➤

Imagine an amazing sports car that could repair itself from damage and automatically change color! Well that’s exactly what Spanish designer Daniel Garcia was thinking of when he created this awesome concept design for the Audi A9. He got some inspiration for this particular design from Santiago Calatrava’s buildings in his hometown of Valencia. Calatrava’s architectural style looks very modern and futuristic, which is exactly what we would describe this car to look like. The windscreen and roof are to be made from a nanotechnology material that can auto-repair and adjust colors. This material isn’t even something that exists right now, so will it be a long time before we actually get to see something like this in action? The idea of it sounds awesome though, right?!

Now, it seems this nascent industry’s time has come. A growing demand for batteries to power electric cars and to store wind and solar energy has driven up the cost of many rare-earth metals and bolstered the business case for sea-bed mining. What’s more, the industry’s long-awaited regulations — in the form of a mining code — are due to be finalized by 2020, putting in place a process whereby contractors can apply for 30-year licences to mine assigned ‘claim areas’ in parts of the international sea bed such as the CCZ. Already, miners are exploring the potential wealth of these claim areas, but no commercial extraction will begin until the regulations are in place. Investments in this industry are now growing.

Plans are advancing to harvest precious ores from the ocean floor, but scientists say that companies have not tested them enough to avoid devastating damage.

Vera Rubin is shown here in 1974, analyzing data from different portions of a galaxy to ascertain its rotational properties. The discovery that the effects of gravity did not trace out the same path that the starlight does was one of the most important discoveries of the 20th century, and brought dark matter into the mainstream of science from the fringes, where it had languished for most of the 20th century. Her work changed our conception of the Universe forever.

Researchers at the Center for Theoretical Physics of Complex Systems (PCS), within the Institute for Basic Science (IBS, South Korea), and colleagues have reported a novel phenomenon, called Valley Acoustoelectric Effect, which takes place in 2-D materials, similar to graphene. This research is published in Physical Review Letters and brings new insights to the study of valleytronics.

In acoustoelectronics, surface (SAWs) are employed to generate . In this study, the team of theoretical physicists modelled the propagation of SAWs in emerging 2-D , such as single-layer molybdenum disulfide (MoS2). SAWs drag MoS2 electrons (and holes), creating an electric current with conventional and unconventional components. The latter consists of two contributions: a warping-based current and a Hall current. The first is direction-dependent, is related to the so-called valleys—electrons’ local energy minima—and resembles one of the mechanisms that explains photovoltaic effects of 2-D materials exposed to light. The second is due to a specific effect (Berry phase) that affects the velocity of these electrons travelling as a group and resulting in intriguing phenomena, such as anomalous and quantum Hall effects.

The team analyzed the properties of the acoustoelectric current, suggesting a way to run and measure the conventional, warping, and Hall currents independently. This allows the simultaneous use of both optical and acoustic techniques to control the propagation of charge carriers in novel 2-D materials, creating new logical devices.
