On January 14, 2005, ESA’s Huygens probe made its descent to the surface of Saturn’s hazy moon, Titan. Carried to Saturn by NASA’s Cassini spacecraft, Huygens made the most distant landing ever on another world, and the only landing on a body in the outer solar system. This video uses actual images taken by the probe during its two-and-a-half hour fall under its parachutes. Huygens was a signature achievement of the international Cassini-Huygens mission, which will conclude on September 15, 2017, when Cassini plunges into Saturn’s atmosphere.
A two minute video shows images taken by ESA’s Huygens probe when it made its descent to the surface of Titan. After a two-and-a-half-hour descent, the metallic, saucer-shaped spacecraft came to rest with a thud on a dark floodplain covered in cobbles of water ice, in temperatures hundreds of degrees below freezing. The alien probe worked frantically to collect and transmit images and data about its environs — in mere minutes its mothership would drop below the local horizon, cutting off its link to the home world and silencing its voice forever.
Although it may seem the stuff of science fiction, this scene played out 12 years ago on the surface of Saturn’s largest moon, Titan. The “aliens” who built the probe were us. This was the triumphant landing of ESA’s Huygens probe.
Huygens, a project of the European Space Agency, traveled to Titan as the companion to NASA’s Cassini spacecraft, and then separated from its mothership on Dec. 24, 2004, for a 20-day coast toward its destiny at Titan.
The probe sampled Titan’s dense, hazy atmosphere as it slowly rotated beneath its parachutes, analyzing the complex organic chemistry and measuring winds. It also took hundreds of images during the descent, revealing bright, rugged highlands that were crosscut by dark drainage channels and steep ravines. The area where the probe touched down was a dark, granular surface, which resembled a dry lakebed.
Featuring Dr. Stan Wagon, Professor of Mathematics - Macalester College. There is no better way to get someone's attention than with an assertion that just seems obviously wrong. Math is full of such things. The talk presents several surprising, even shocking, things from elementary mathematics, such as: A square wheel that rolls perfectly smoothly. A device that uses a normal rotating crankshaft to drill perfect square holes. An application of a non-circular wheel to sewage disposal. A shocking cake puzzle. Surprising new formulas for π. Benford's mysterious law of first digits. The Banach-Tarski Paradox, with constructible pieces.

Project Jupyter provides building blocks for interactive and exploratory computing. These building blocks make science and data science reproducible across over 40 programming language (Python, Julia, R, etc.). Central to the project is the Jupyter Notebook, a web-based interactive computing platform that allows users to author data- and code-driven narratives - computational narratives - that combine live code, equations, narrative text, visualizations, interactive dashboards and other media.
Viruses are by far the most abundant biological entities in the oceans, comprising approximately 94% of the nucleic-acid-containing particles. However, because of their small size they comprise only approximately 5% of the biomass. By contrast, even though prokaryotes represent less than 10% of the nucleic-acid-containing particles they represent more than 90% of the biomass.
Self-assembling robots are referred to as von Neumann machines after the man responsible for originally proposing them, John von Neumann. Since then, the potential of these machines and their ability to proliferate throughout known space has made galactic colonization seem not only possible but perhaps inevitable.

What makes us different from all these things? What makes us different is the particulars of our history, which gives us our notions of purpose and goals. That's a long way of saying when we have the box on the desk that thinks as well as any brain does, the thing it doesn't have, intrinsically, is the goals and purposes that we have. Those are defined by our particulars—our particular biology, our particular psychology, our particular cultural history.
The thing we have to think about as we think about the future of these things is the goals. That's what humans contribute, that's what our civilization contributes—execution of those goals; that's what we can increasingly automate. We've been automating it for thousands of years. We will succeed in having very good automation of those goals. I've spent some significant part of my life building technology to essentially go from a human concept of a goal to something that gets done in the world.
There are many questions that come from this. For example, we've got these great AIs and they're able to execute goals, how do we tell them what to do?...

If six unordered points are given on a conic section, they can be connected into a hexagon in 60 different ways, resulting in 60 different instances of Pascal's theorem and 60 different Pascal lines. This configuration of 60 lines is called the Hexagrammum Mysticum.
As Thomas Kirkman proved in 1849, these 60 lines can be associated with 60 points in such a way that each point is on three lines and each line contains three points. The 60 points formed in this way are now known as the Kirkman points. The Pascal lines also pass, three at a time, through 20 Steiner points. There are 20 Cayley lines which consist of a Steiner point and three Kirkman points. The Steiner points also lie, four at a time, on 15 Plücker lines. Furthermore, the 20 Cayley lines pass four at a time through 15 points known as the Salmon points.
Quantum computing promises to revolutionize how we compute and change the way we use technology in our daily lives.
Dr. Krysta Svore, Senior Researcher at Microsoft Research in Redmond, Washington, reveals some of the mysteries of this disruptive computational paradigm and showcase real-world applications of quantum devices.
Cancer therapies that target specific pathways can be more effective than established, nonspecific chemotherapy and radiation treatments, and may prevent side effects on healthy tissues. Such targeted therapies can only be applied after underlying gene mutations have been identified. However, detecting low frequency variants from clinically relevant samples poses significant challenges. Specimens are routinely formalin-fixed and paraffin-embedded (FFPE) for histology, which can decrease the efficiency of NGS library preparation. In this presentation, we discuss approaches for extraction of DNA from FFPE samples, and recommend quality control assays to guide parameter selection for library construction and sequencing depth.
In this talk, Author/artist Michael Carroll will explore the bizarre methane-filled seas and soaring dunes of Saturn's largest moon, Titan. Recent advances in our understanding of this planet-sized moon provide enough information for authors to paint a realistic picture of this truly alien world. Following his presentation, he will be signing his new science fiction adventure/mystery book, "On the Shores of Titan's Farthest Sea".
"Carroll's descriptions of oily seas and methane monsoons put you in that alien world, front and center…I can imagine future astronauts doing exactly the kinds of things Mike describes. I wish I could be one of them." Alan Bean, Apollo 12 astronaut.
Measurements of the demographics of exoplanets over a range of planet and host star properties provide fundamental empirical constraints on theories of planet formation and evolution. Because of its unique sensitivity to low-mass, long-period, and free-floating planets, microlensing is an essential complement to our arsenal of planet detection methods.
Dr. Gaudi will review the microlensing method, and discuss results to date from ground-based microlensing surveys. Also, Dr. Gaudi will motivate a space-based microlensing survey with WFIRST-AFTA, which when combined with the results from Kepler, will yield a nearly complete picture of the demographics of planetary systems throughout the Galaxy.
When diffraction is employed as the primary collector modality of a telescope instead of reflection or refraction, a new set of performance capabilities emerges. A diffraction-based telescope forms a spectrogram first and an image as secondary data. The results are startling. In multiple object capability, the diffraction telescope on earth can capture 2 million spectra to R bigger than 100,000 in a single night, better for a census of exoplanets by radial velocity than any prior art. In a space telescope in a direct observation mode, this type diffraction primary objective could reveal spectral analyses of individual exoplanets.
Dr Stephen Wolfram, founder & CEO of Wolfram Research, and creator of Mathematica, Wolfram|Alpha and the Wolfram Language will come to the SETI Institute to discuss his latest thinking about the relation between searching for complex behavior in the computational universe of simple programs, using this in creating AI, and searching for intelligence elsewhere in our physical universe.
Andreas Dewes explains why quantum computing is interesting, how it works and what you actually need to build a working quantum computer. He uses the superconducting two-qubit quantum processor which he built during his PhD thesis as an example to explain its basic building blocks. He shows how this processor can be used to achieve so-called quantum speed-up for a search algorithm that can be run on it. Finally, he gives a short overview of the current state of superconducting quantum computing and Google's recently announced effort to build a working quantum computer in cooperation with one of the leading research groups in this field.
Google recently announced that it is partnering up with John Martinis - one of the leading researchers on superconducting quantum computing - to build a working quantum processor. This announcement has sparked a lot of renewed interest in a topic that was mainly of academic interest before. So, if Google thinks it's worth the hassle to build quantum computers then there surely must be something about them after all?
