| Posted: 16 Nov 2018 04:35 AM PST Many women who work in the STEM industries still feel stuck in their careers. Our latest study, "Wonder Women in STEM and the Companies that Champion Them," identifies several strategies that can foster career advancement for women in these fields. I'm Julia Taylor Kennedy, Executive Vice President and Director of Publications at CTI, and I'm Pooja Jain-Link, Senior Vice President and CTI's Director of Research. We're familiar with the challenges women face as they attempt to climb the ladder to the C-Suite in science, technology, engineering, and math (STEM) fields--challenges that often lead them to lean out of their industries entirely. Our latest report shifts from documenting challenges to identifying actionable approaches linked to success for individuals as well as companies. We are excited to talk to you about this study and welcome questions from women currently working in STEM careers in particular. We'll be on at 4pm ET (21 UT). Ask Us Anything! [link] [comments]  |
| The new kilogram definition seems complex. Why not define it in terms of the mass of a proton? Posted: 16 Nov 2018 07:19 AM PST The kilogram is being redefined. https://www.vox.com/science-and-health/2018/11/14/18072368/kilogram-kibble-redefine-weight-science The new definition is in terms of the Planck constant and seems complex (or at least not very elegant.) Why isn't the kilogram defined as something simpler like the mass of X number of protons? [link] [comments]  |
| What determines how opaque or transparent a material is, on a molecular level? Posted: 16 Nov 2018 04:16 AM PST Like what makes water clear? What makes milk white? How can something even be transparent? [link] [comments]  |

| With current nuclear reactors' consumption, how much "fuel" do we have left? Posted: 15 Nov 2018 11:51 PM PST Hi, I am part of those that think that the best way to reduce global warming and keep our ways of life while not polluting the environment too much is to commit to nuclear fission. I know that there are problems with waste, but I consider them insignificant compared to global warming. I know that there are renewables, but to use them in the next 10 years, we might (not knowledgable enough) have to drastically reduce our consumption. So with that in mind, I am an advocated of nuclear fisison. A colleague of mine said that there are only a few decades of fissable material left to make sure current reactors can keep running. This seems like a difficult topic for me to get the right data. So, is that true that we are also running out of fuel for our nuclear reactors? If not, could the world run mostly on nuclear?

| Can someone help me find the spectra of the TRAPPIST-1 Exoplanets? Posted: 16 Nov 2018 02:00 AM PST Hello, I am looking for the data for the TRAPPIST-1 system spectra for the exoplanets. I have seen many plots of this data, but cannot find the raw numbers, which I need for a college project. If anyone could help my find the numerical values for these spectra, it would be most appreciated. [link] [comments]  |

| Posted: 16 Nov 2018 01:48 AM PST Also, when was the last element on the table discovered? There has to be some that we haven't discovered on other planets or in other galaxies at least, right? [link] [comments]  |
