Hi Reddit! I’m Gerbrand Ceder, though I go by “Gerd” as my first name. I’m the lead scientist for multi-valent batteries at the Joint Center for Energy Storage at Berkeley Lab, and a faculty scientist in the Materials Sciences Division at Berkeley Lab. I am also the Chancellor’s Professor of Materials Science and Engineering at UC Berkeley. I look forward to answering your questions about building better batteries for a better future. Recently, my team and I shed light on how lithium-rich cathodes work, which could lead to higher capacity batteries. You can read about that here. And here is my website. I received an engineering degree from the University of Leuven, Belgium, and a Ph.D. in Materials Science from the University of California at Berkeley in 1991. Between 1991 and 2015, I was a Professor in Materials Science at the Massachusetts Institute of Technology and braved the hard Massachusetts winters. As a college student in engineering I was fascinated by the tremendous impact novel materials could have on society, and decided to make it my career to come up with more rational methods to design novel materials, rather than just “try and see.” I rode the wave of computing growth and became one of the first “computational materials designers.” In the early 90’s I got involved with Li-ion batteries, at the time a very nascent technology. It has been a wild ride since then, seeing the multiple waves of impact this technology is having as it moves from portable electronics to vehicles, and now to grid. The little time I am not working I enjoy listening to loud music, baking bread (preferably at the same time), or doing a good hike. I look forward to your questions. Edit: I’m live and answering your questions. Thanks to everyone who has submitted thus far. I’ll be answering until 3p ET/12p PT. Here we go… Edit: It’s noon and my laptop battery is at 2%… So, I must go! Thanks for joining me today. Be sure to check out the links above and below for more on battery research and stay tuned for more science reddit AMAs from Berkeley Lab. Cheers! Berkeley Lab Joint Center for Energy Storage
Hi Reddit! Karl here. I am a professor of Chemistry and Biochemistry at the University of Delaware. I have a successful research group with over 100 publications and 5 patents on the design and application of chemical sensors. I’m a Fellow of the American Chemical Society and Fellow of the Society for Applied Spectroscopy. I broke my neck BASE jumping in the Grand Canyon during Spring Break my freshman year of college. OK, really it was playing flag football, but I’m working on a much sexier legend. I’ve been active in promoting inclusion of underrepresented groups, especially persons with disabilities in STEM for the past 15 years. I’ve chaired the ACS Committee on Chemists with Disabilities and am current chair of the ACS Diversity and Inclusion Advisory Board. I’m also Principal Investigator on a newly renewed NSF research experience for undergraduates (REU) grant to get research experience for students with disabilities interested in advanced STEM degrees. http://sites.udel.edu/seli-ud/ People with disabilities (PWD) continue to be a greatly underrepresented group in Science Technology, Engineering and Mathematics (STEM). PWD comprise 7% of the population between 16 and 21 (US Census) and 8.6% of the total school population participates in the Individuals with Disabilities Education Act (IDEA). Students with disabilities express interest in STEM at the same rate as students without disabilities. Approximately 20% of graduating high school seniors and ~20% of graduating college seniors wish to continue towards a higher degree in STEM. However, less than 2% of STEM doctoral degrees earned by US citizens or permanent residents are awarded to students who identify as having a disability! Remove soft sciences from the equation and the rate drops to 1%. Amazingly there has been no improvement in PWD doctoral students since the passage of the Americans with Disabilities Act (ADA) in 1991: there is no statistical increase in the percentage of earned STEM doctoral degrees by PWD among US citizens or permanent residents at US institutions (see this figure http://i.imgur.com/3LPJMjN.png). Factor in foreign national students to get the statistics on all STEM doctoral degrees awarded by US institutions and the trend becomes negative improvement. Across the same time frame, the percentage of STEM doctoral degrees earned by African American and Hispanic students each increased by 0.16 or 0.17 percentage points per year on average. Federal support and interest in the outcome may well be a factor. The 2010 Federal STEM Education Inventory Data Set on broadening participation (data.gov) shows $397.8M dedicated to ‘Institutional Capacity’ or ‘Postsecondary STEM’ with $378.3M earmarked for underrepresented minorities and only $19.6M dedicated to students with disabilities. This is a 19:1 ratio! I will be back at 1 pm ET, Ask me anything about getting more opportunities in STEM research and careers for people with disabilities! Hi All! I’m on live now. I’ll probably stay live a bit past 2:00 pm EST. I type slowly. /ksb I’ll drop back in later tonight after my kids go to bed to get to the rest of the great questions. /ksb There is a couple of questions that I haven’t gotten to. I’ll try to hit those tomorrow, but I have a proposal that I need to wrap up in the next 24 hours. /ksb

As previously announced, /r/philosophy is hosting an AMA series this fall semester which kicks off this upcoming Tuesday August 30th, 1PM EST. Caspar Hare, Professor of Philosophy at MIT, will be joining us to answer questions about his work on ethics, rationality and a special edX course he is running called “Introduction to Philosophy: God, Knowledge and Consciousness”. Professor Hare has published two books, The Limits of Kindness and On Myself, and Other, Less Important Subjects. You can read free online reviews of those books here and here respectively. He has also published a number of papers, all of which are available online at his website for free. Check out some blurbs for his books below: The Limits of Kindness Caspar Hare presents a novel approach to questions of what we ought to do, and why we ought to do it. The traditional way to approach this subject is to begin by supposing a foundational principle, and then work out its implications. Consequentialists say that we ought to make the world impersonally better, for instance, while Kantian deontologists say that we ought to act on universalizable maxims. And contractualists say that we ought to act in accordance with the terms of certain hypothetical contracts. These principles are all grand and controversial. The motivating idea behind The Limits of Kindness is that we can tackle some of the most difficult problems in normative ethics by starting with a principle that is humble and uncontroversial. Being moral involves wanting particular other people to be better off. From these innocuous beginnings, Hare leads us to surprising conclusions about how we ought to resolve conflicts of interest, whether we ought to create some people rather than others, what we ought to want in an infinite world, when we ought to make sacrifices for the sake of needy strangers, and why we cannot, on pain of irrationality, attribute great importance to the boundaries between people. On Myself, and Other, Less Important Subjects Caspar Hare makes an original and compelling case for “egocentric presentism,” a view about the nature of first-person experience, about what happens when we see things from our own particular point of view. A natural thought about our first-person experience is that “all and only the things of which I am aware are present to me.” Hare, however, goes one step further and claims, counterintuitively, that the thought should instead be that “all and only the things of which I am aware are present.” There is, in other words, something unique about me and the things of which I am aware. On Myself and Other, Less Important Subjects represents a new take on an old view, known as solipsism, which maintains that people’s experiences give them grounds for believing that they have a special, distinguished place in the world–for example, believing that only they exist or that other people do not have conscious minds like their own. Few contemporary thinkers have taken solipsism seriously. But Hare maintains that the version of solipsism he argues for is in indeed defensible, and that it is uniquely capable of resolving some seemingly intractable philosophical problems–both in metaphysics and ethics–concerning personal identity over time, as well as the tension between self-interest and the greater good. Professor Hare is teaching a free online MOOC this semester called Introduction to Philosophy: God, Knowledge and Consciousness. You can read an article about the MOOC by MIT News here. This iteration of 24.00x is (to our knowledge) the first philosophy MOOC in history to offer instructor grading of, and comments on, your work. Basically you get to do philosophy for real, with individual instruction, for a small fraction of the cost of taking the course at MIT. The blurb for the course is as follows: This philosophy course has two goals. The first goal is to introduce you to the things that philosophers think about. We will look at some perennial philosophical problems: Is there a God? What is knowledge, and how do we get it? What is the place of our consciousness in the physical world? Do we have free will? How do we persist over time, as our bodily and psychological traits change? The second goal is to get you thinking philosophically yourself. This will help you develop your critical reasoning and argumentative skills more generally. Along the way we will draw from late, great classical authors and influential contemporary figures. AMA Professor Hare will join us this Tuesday for a couple hours of live Q&A on his work and teaching, as well as philosophy and education more generally. Please feel free to post questions for Professor Hare here. He will look at this thread before he starts and begin with some questions from here while the initial questions in the new thread come in. Please join me in welcoming Professor Hare to our community!

Reddit-ors! As someone who started off as a drug designer in the pharmaceutical and chemical industries I have always had a keen interest in natural products. Consequently I have worked for many years in the use of plant and natural products for things like improving human health, colours, food ingredients, shelf life extension etc. Over the last decade or so I have become passionate about fully utilizing crops and plants and am leading efforts into promoting and realizing a circular economy approach to agriculture and industry. A circular economy is an alternative to a traditional linear economy (make, use, dispose) in which we keep resources in use for as long as possible and get the most use out of them, then recover and regenerate products and materials at the end of each service life. Can we take this forward in plant and crops science, and industries? I think sustainability is key to our continued survival and lifestyles. I am on the Sense About Science’s Plant Science Panel, where you can put questions and opinions for response from researchers. The Panel is made up of over 50 independent plant science researchers. You can ask questions to them on Twitter (@senseaboutsci #plantsci) Facebook or using this online form. Answers are sent back within a couple of days and posted online. The Panel has answered close to 400 questions over the last three years and it’s a great want to cut through the noise around what can sometimes be a really polarised debate. I will be back at 12 am EDT (5 pm GMT, 9 am PST) to answer all your questions.
