| Posted: 18 Jun 2018 04:00 AM PDT Prof. Dr. Max Welling is a research chair in Machine Learning at the University of Amsterdam and a VP Technologies at Qualcomm. He has a secondary appointment as a senior fellow at the Canadian Institute for Advanced Research (CIFAR). He is co-founder of "Scyfer BV" a university spin-off in deep learning which got acquired by Qualcomm in summer 2017. In the past he held postdoctoral positions at Caltech ('98-'00), UCL ('00-'01) and the U. Toronto ('01-'03). He received his PhD in '98 under supervision of Nobel laureate Prof. G. 't Hooft. Max Welling has served as associate editor in chief of IEEE TPAMI from 2011-2015 (impact factor 4.8). He serves on the board of the NIPS foundation since 2015 (the largest conference in machine learning) and has been program chair and general chair of NIPS in 2013 and 2014 respectively. He was also program chair of AISTATS in 2009 and ECCV in 2016 and general chair of MIDL 2018. He has served on the editorial boards of JMLR and JML and was an associate editor for Neurocomputing, JCGS and TPAMI. He received multiple grants from Google, Facebook, Yahoo, NSF, NIH, NWO and ONR-MURI among which an NSF career grant in 2005. He is recipient of the ECCV Koenderink Prize in 2010. Welling is in the board of the Data Science Research Center in Amsterdam, he directs the Amsterdam Machine Learning Lab (AMLAB), and co-directs the Qualcomm-UvA deep learning lab (QUVA) and the Bosch-UvA Deep Learning lab (DELTA). He will be with us at 12:30 ET (ET, 17:30 UT) to answer your questions! [link] [comments]  |
| If Thorium is so abundant and cheap, why is it so hard to get a sample of? Posted: 17 Jun 2018 09:08 PM PDT This video from "Periodic Table of Videos" stresses how hard to get Thorium is, but every proponent of Thorium ever has noted that a major benefit of thorium is that it is so abundant and cheap to mine... So which is it, and if it's both, then how is this inconsistency settled? Are people just throwing away Thorium because it has no use currently? I would still expect there to be SOMEONE selling nice thorium spheres or cubes for classrooms... Edit: I'll clarify that I'm not asking about Thorium reactors or LFTRs or MSRs.... Just why is it so hard for a chemist to get a sample, and when he does why is that sample so tiny? As far as I understand Thorium emits only alpha particles which are easily stopped by the lightest of shielding and might even be safe to handle with only gloves... I'd assume someone would be selling chunks of it! [link] [comments]  |

| Posted: 17 Jun 2018 02:29 PM PDT I've flaired this as Astronomy, but I'm not exactly sure if it 100% fits this category. Didn't seem like Planetary Sciences was the right choice, either. [link] [comments]  |
| What is the most efficient mechanism for converting matter to energy? Posted: 17 Jun 2018 09:35 PM PDT At the moment the most efficient I know of would be nuclear fusion. Is there anything that's more efficient? [link] [comments]  |
| How do engineers determine their recommendations for an engine's oil? Posted: 17 Jun 2018 11:02 PM PDT Aside from the obvious climate rating, what determines if an engine requires heavy or thin oil? How can Mobil oil be the recommended oil for Porsche engines? [link] [comments]  |
| Is energy always conserved? Are there exceptions ? Posted: 18 Jun 2018 04:14 AM PDT This video suggests that this isn't the case. During red-shift of photon, the energy is simply lost! Questions:
PS: Physics is clearly not my forte :P [link] [comments]  |

| Posted: 18 Jun 2018 05:33 AM PDT The probability is 1 - (5/6)2 whereas the intuitive solution would be 2 x 1/6 What maths phenomenon makes it so that the probability of "not being a 6" the way to have to solution ? Does it have to do with independance of the throws ? [link] [comments]  |

| Can your ears "pop" from air pressure change from weather fronts? Posted: 17 Jun 2018 10:01 PM PDT I work at a lake and today that was a storm that rolled in during my shift. I was outside working while it came and and started to pour. I began to feel that weird thing in my ears like there was pressure. It was raining a lot and I work at a lake (I wasn't swimming in the water) so it could have been water in my ears. I'm just wondering if the pressure change from different types of fronts can affect people. [link] [comments]  |

| Posted: 17 Jun 2018 03:49 PM PDT And did the other humanoid species travel at the same time but just die before getting to modern day Russia? I guess the main question is how long from Africa to The Americas. [link] [comments]  |
| Posted: 17 Jun 2018 08:35 PM PDT If a hole was drilled through the centre of the Earth and an object was dropped in it, would it come out the other end? How would gravity affect the object as it passed the equator and the gravitational force was flipped? Would there be a difference in how the object acted if you dropped it from north pole to south pole vs east side of the earth to west? [link] [comments]  |
| Posted: 17 Jun 2018 12:49 PM PDT Given how when we observe objects farther than a light-year away we are technically seeing the past, is it possible to one day build something capable of seeing far enough away that we would see the big-bang or the very early effects of it? [link] [comments]  |

| How do alcoholic drinks have sugar in them if yeast consumes sugar in order to make alcohol? Posted: 17 Jun 2018 06:55 PM PDT I understand that some alcoholic beverages may start as a juice (wine for example) which is high in sugar but yeast is supposed to consume sugar and as a byproduct make alcohol. Despite this a lot of alcoholic beverages have a lot of sugar in them. Why doesn't the yeast just consume all of the sugar? [link] [comments]  |
