| Posted: 16 Mar 2018 04:00 AM PDT Jessica Pierce is a bioethicist who has extensively written about bioethics and animals. Bioethics is a field of research that sits at the crossroads of biomedical sciences and ethics, and bioethicists explore ethical issues in the biomedical sciences. Jessica has authored or co-authored more than 30 articles in peer reviewed journals, and writes for many publications including The New York Times, The Wall Street Journal, and Scientific American. Her recent article, "You Love Dogs? Don't Clone Them" makes a case against cloning pets. Jessica also publishes a blog on Psychology Today. Here is her blog. Her published works include Run, Spot, Run: The Ethics of Keeping Pets which discusses moral ambiguities in pet ownership, The Last Walk: Reflections on Our Pets at the Ends of Their Lives which discusses caring for pets in the end of their lives, and Wild Justice: The Moral Lives of Animals, which discusses prosocial behaviors in pets. More information about Jessica can be found on her website. She'll be joining starting at 3:30 ET (1930 UT)! [link] [comments]  |
| What is a Lagrangian? What is the action? Why does the principle of least (stationary) action work? Posted: 15 Mar 2018 11:02 PM PDT I've gone through the procedure in class. I've gone through it again watching Leonard Susskind's online lectures. Newton's equations pop out... or whatever correct equations we're looking for ... and I have no idea why. Why should this procedure work? Please help me- I feel like I'm a wizard invoking spellcraft. [link] [comments]  |

| What does Particle Horizon growth mean to observer? Posted: 16 Mar 2018 05:17 AM PDT I've read this title Still I can't get this: "Note that the particle horizon grows over time. So more and more galaxies become visible until the end of time." So as for now these galaxies out of PH or inside?
Does it mean we can find galaxy in a distance between 32 (the most distant galaxy we see already) & 47 (PH) Gyr NOW but in a future we would be able to find something closer than 65 Gyr? So 65 Gyr boundary isn't increasing in time? So in infinte perspective PH is limited by 65 Gyr? [link] [comments]  |

| Does using a graphics card create "wear and tear" on the GPU? Posted: 15 Mar 2018 08:53 AM PDT Take a graphics card that is run 24/7 for two years as part of a crypto mining operation. Assume that heat is never an issue because it's sufficiently cooled and that its undervolted like most miners do. What kind of "wear and tear" is applied to the GPU and ram chips through constant use? [link] [comments]  |

| Posted: 15 Mar 2018 12:54 PM PDT When I look at picture of Kepler, I can see solar panels. Is the power coming from those panels insufficient to keep the telescope in orbit? Could a future telescope run entirely off of solar or will a fuel source always be required?

| How long does it take for a new island to get colonised by plant and animal life? Posted: 15 Mar 2018 10:26 PM PDT This is in the context of either islands formed due to the resurfacing of an older land mass or the eruption of volcanoes. [link] [comments]  |
| Do sunspots have antipodal sunspots? Posted: 15 Mar 2018 05:44 PM PDT I just learned that sunspots are a result of magnetism (forgive me if I get the phrasing wrong). This idea came from the fact that celestial bodies, for the most part have magnetic fields. (Assuming that if sunspots do have antipodal sunspots, they don't necessarily have to be equal in size, they merely have to exist) [link] [comments]  |
