Dr. Penelope Boston: "Seeking the Tricorder: The Hunt for Extraterrestrial Life" | Talks at Google
The hunt for life in extraterrestrial environments and in extreme environments on Earth presents challenging problems in exploration strategy, engineering, and science. Our success depends on the magic that happens when new tools and techniques are developed, which allows us to look at the world in new ways and from new perspectives. In this talk, Dr. Boston discusses issues and new directions in robotics, machine learning, and life detection technologies that are changing the way NASA explores our universe for other lifeforms. Dr. Boston is Director of the NASA Astrobiology Institute, which supports the study of the origins, evolution, distribution, and future of life in the universe. From 2002-2016, Dr. Boston was the Associate Director of the National Cave and Karst Research Institute and Professor and Chair of the Earth and Environmental Sciences Dept. at the New Mexico Institute of Mining and Technology. Dr. Boston received her Ph.D. from the University of Colorado, Boulder and was awarded the "Caving Legend Award" from the Ft. Stanton Cave Study Project/Bureau of Land Management.

A Spaceship Named McGuire by Randall Garrett
Can a spaceship go crazy? Well, yes it can if it has a brain. And the new MG (magnetogravitic drive) experimental robot space ship does indeed have a 'brain'. Completely bewildered as to why the first six models of their supposedly perfect new ship model, the MG-YR, nicknamed the McGuire, have gone totally bonkers after activation and before they could ever be used, the company has called in the services of Daniel Oak. They suspect sabotage of course. Daniel Oak is the hard boiled private investigator with nerves of steel and a mind of the same substance. He is extremely expensive to hire but gets results; and he knows his way around crime, space ships and especially women.

Archaeology and Futurity Conference Session 3: Contemporary Encounters and Speculative Futures
Friday, April 15, 2016 Session 3: Contemporary Encounters and Speculative Futures Joukowsky Institute for Archaeology and the Ancient World In a particularly troubling academic climate that is witnessing departmental amalgamation and a relative dearth in full-time faculty hires, how does the discipline of archaeology envision its future? What is its role beyond the walls of the academy? Should archaeology be useful and, if so, for what purposes? This conference addresses archaeology’s potential role in contributing to pressing world problems including climate change, economic inequality, human rights, neocolonialism, and militarism. This conference also seeks to address how futurity plays a role in how archaeologists confront the past in the present. Through a departure from linear time, this conference will explore alternative notions of time, material vestiges of the past in the present, and embodied experiences that transcend temporalities. If we accept that archaeology is a discipline about the present, how are we to think about time and futurity? Session Participants: O. Hugo Benavides (Fordham University) "History, Capitalism, and Postcolonial Identities: An Archaeology of the Future" Christopher Witmore (Texas Tech University) "Hypanthros: How Might Archaeologists Approach that which is in Excess of Monstrosity?" Uzma Rizvi (Pratt University) "Future Participle: Towards a Speculative Archaeology" **Some images used by presenters are copyrighted materials NOT owned by individual presenters.

Drilling rig
A drilling rig is a machine which creates holes in the ground. Drilling rigs can be massive structures housing equipment used to drill water wells, oil wells, or natural gas extraction wells, or they can be small enough to be moved manually by one person and are called augers. sample sub-surface mineral deposits, test rock, soil and groundwater physical properties, and also can be used to install sub-surface fabrications, such as underground utilities, instrumentation, tunnels or wells. Drilling rigs can be mobile equipment mounted on trucks, tracks or trailers, or more permanent land or marine-based structures (such as oil platforms, commonly called 'offshore oil rigs' even if they don't contain a drilling rig). The term "rig" therefore generally refers to the complex of equipment that is used to penetrate the surface of the Earth's crust. This video is targeted to blind users.

Sodium chloride
Sodium chloride, also known as salt, common salt, table salt or halite, is an ionic compound with the formula NaCl, representing equal proportions of sodium and chlorine. Sodium chloride is the salt most responsible for the salinity of the ocean and of the extracellular fluid of many multicellular organisms. In the form of edible or table salt it is commonly used as a condiment and food preservative. Large quantities of sodium chloride are used in many industrial processes, and it is a major source of sodium and chlorine compounds used as feedstocks for further chemical syntheses. A second major consumer of sodium chloride is deicing of roadways in sub-freezing weather. This video is targeted to blind users.

Written language only began at around 3200 BC, but spoken language has existed long ago. Learning by listening is a great way to: - increases imagination and understanding - improves your listening skills - improves your own spoken accent - learn while on the move - reduce eye strain Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone.

Productivity in general is a ratio of output to input in the production of goods and services. Productivity is increased by lowering the amount of labor, capital, energy or materials that go into producing any given amount of economic goods and services. Increases in productivity are largely responsible for the increase in per capita living standards.

Robotics is the branch of technology that deals with the design, construction, operation, and application of robots, as well as computer systems for their control, sensory feedback, and information processing. These technologies deal with automated machines that can take the place of humans in dangerous environments or manufacturing processes, or resemble humans in appearance, behavior, and/or cognition. Many of today's robots are inspired by nature contributing to the field of bio-inspired robotics. The concept of creating machines that can operate autonomously dates back to classical times, but research into the functionality and potential uses of robots did not grow substantially until the 20th century. Throughout history, robotics has been often seen to mimic human behavior, and often manage tasks in a similar fashion. Today, robotics is a rapidly growing field, as technological advances continue, research, design, and building new robots serve various practical purposes, whether domestically, commercially, or militarily. Many robots do jobs that are hazardous to people such as defusing bombs, mines and exploring shipwrecks. This video is targeted to blind users.
