| Could a GPU be custom built for a specific problem so that it solves it faster than a standard GPU? Posted: 31 Jul 2019 10:49 PM PDT I've heard some problems take weeks to solve, even on some of Google's processors used in research . Do GPU's sacrifice speed for 'versatility?' Or is the hardware already fully optimized to a variety of machine learning problems? [link] [comments]  |
| Can dogs percieve the 60 Hz flickering of a light bulb? Posted: 31 Jul 2019 07:21 PM PDT I learned today that human stop perceiving flickering of a light source above 55Hz. I also learned that dogs can percieve that flickering up to 80Hz. Does that mean that every night when I turn my lights on, which flicker at 60Hz, my dog thinks he is living in an insane strobe-light madhouse? [link] [comments]  |
| Posted: 01 Aug 2019 07:40 AM PDT This is prompted by a discussion on a translation of an English book into German. A favorite truism online is that English does not "just borrow words; on occasion, [it pursues] other languages down alleyways to beat them unconscious and rifle their pockets for new vocabulary", as if it is something unique to our tongue. I've also seen many statements that on pure word count, ours is one of, if not the largest vocabularies in the world. As a Germanic language with heavy influence from Greek, Latin, and French, I know English has a diverse vocabulary, with a lot of nuance between very similar words. For example, huge, giant, titanic, colossal, and enormous all mean large but definitely have different contextual meanings, as do pleased, contented, satisfied, elated, cheerful, and ecstatic. In the discussion I was reading, the example that prompted this question was that, in German, the word for both "hound" and "dog" is "Hund", requiring the name of The Hound from A Game of Thrones to be changed to Bluthund for contextual story reasons (he is called Dog derogatorily by another character) and that grew into a larger conversation on the subtleties of synonyms across languages and now this thread, where I'm looking for more of a learned answer. Is English particularly expressive? [link] [comments]  |
| At what point are related species unable to breed together? Posted: 01 Aug 2019 07:34 AM PDT I saw an repost about human/Neanderthal interbreeding and wondered at what point in an species' evolution it couldn't be interbred with related species/those with a common ancestor. [link] [comments]  |

| Posted: 31 Jul 2019 11:08 PM PDT Is there a tipping point where a planet's atmosphere and other factors make it suitable for making it habitable? If so, what are they looking for? [link] [comments]  |
| Posted: 31 Jul 2019 08:52 AM PDT Is there a sort of diminishing return on healing based on how much the body needs to do? For instance if I have two similar cuts on each hand, will they heal slower than if I had only one cut on one hand? [link] [comments]  |
| Posted: 01 Aug 2019 04:41 AM PDT For example, a mother bird having different chirps for each of her chicks. Or a monkey having an individual calls for each friend. [link] [comments]  |
| How is the lithosphere affected by global warming? Posted: 01 Aug 2019 04:08 AM PDT Global warming affects the entire planet in numerous ways. It affects the atmosphere by having higher concentrations of CO2, it affects the biosphere because living things need oxygen to survive. It affects the hydrosphere with ocean temperatures increasing each year. It affects the cryosphere with mass ice sheet loss. However, I cannot understand how the lithosphere is affected (for a science assignment). Any ideas? [link] [comments]  |
| Energy of the electrons, How does it allow metals to actually conduct electricity? Posted: 01 Aug 2019 12:08 AM PDT I'm a high school student going into the 10th grade, I'm wanting to pursue some sort of electrical engineering job, after college. One thing that I want to understand before I figure out how to engineer the stuff, is how does metal conduct electricity? Also, how does the energy of the electrons in the metals allow them to conduct electricity? How fast is the transfer of energy to create electricity? [link] [comments]  |
| Why don’t the space probes get fried at the End of the Heliosphere? Posted: 31 Jul 2019 06:08 PM PDT I've read that the heliosphere (especially the termination shock) is where all the the solar wind converge, and then smack into the interstellar wind, and abruptly drop off. Would that mean because of the drop off the spacecraft can safely pass? But then what about the interstellar wind? Why doesn't that hurt the spacecraft? I've always wondered about this, but haven't found any answers online. [link] [comments]  |

| How does the jaw heal after pulling a tooth? Posted: 31 Jul 2019 03:41 PM PDT I had a wisdom tooth surgically removed today. How does the bone in my jaw heal? What will the space where the roots of my tooth be filled with? After the tooth was removed, the doctor stiched my gum together, covering the hole. What will happen to the blood that filled the hole when my gum heals and seals the space with "loose" blood in it? [link] [comments]  |

| How do we know what colors animals see? Posted: 31 Jul 2019 04:36 PM PDT How can we know that dogs see yellows/greys/blues? On top of this, i have heard that babies only see in black and white for the first weeks/months, (if this is true) how can we know all this? [link] [comments]  |

| Ask Anything Wednesday - Engineering, Mathematics, Computer Science Posted: 31 Jul 2019 08:13 AM PDT Welcome to our weekly feature, Ask Anything Wednesday - this week we are focusing on Engineering, Mathematics, Computer Science Do you have a question within these topics you weren't sure was worth submitting? Is something a bit too speculative for a typical /r/AskScience post? No question is too big or small for AAW. In this thread you can ask any science-related question! Things like: "What would happen if...", "How will the future...", "If all the rules for 'X' were different...", "Why does my...". Asking Questions: Please post your question as a top-level response to this, and our team of panellists will be here to answer and discuss your questions. The other topic areas will appear in future Ask Anything Wednesdays, so if you have other questions not covered by this weeks theme please either hold on to it until those topics come around, or go and post over in our sister subreddit /r/AskScienceDiscussion , where every day is Ask Anything Wednesday! Off-theme questions in this post will be removed to try and keep the thread a manageable size for both our readers and panellists. Answering Questions: Please only answer a posted question if you are an expert in the field. The full guidelines for posting responses in AskScience can be found here. In short, this is a moderated subreddit, and responses which do not meet our quality guidelines will be removed. Remember, peer reviewed sources are always appreciated, and anecdotes are absolutely not appropriate. In general if your answer begins with 'I think', or 'I've heard', then it's not suitable for /r/AskScience. If you would like to become a member of the AskScience panel, please refer to the information provided here. Past AskAnythingWednesday posts can be found here. Ask away! [link] [comments]  |
| Do astronauts or cosmonauts suffer vertigo while out on a spacewalk? Posted: 31 Jul 2019 08:09 PM PDT The reason I ask this is that I feel queesy once I get above 5 stories in a high-rise.. i ain't great with high elevations, ( yeah I know. A wuss 😂 ) and after scrolling through Twitter, then seeing a photo from NASA's Twitter account from a spacewalk on the ISS. the thought occurrenced to me... Do astronauts or cosmonauts suffer from similar feelings while out on space walks? The apprehension and weak knees from looking down upon the earth from 250 miles above the surface. Can you even get into a astronaut program if you suffer from a fear of high places? [link] [comments]  |
| Why do Hydrogen and Helium have such high thermal conductivity compared to other gases? Posted: 31 Jul 2019 09:01 AM PDT "The value of thermal conductivity for most gases and vapors range between 0.01 and 0.03 W/mK at room temperature. Notable exceptions are Helium (0.15) and Hydrogen (0.18)" www.electronics-cooling.com/1998/09/the-thermal-conductivity-of-gases/ Why is this? [link] [comments]  |
