| Posted: 02 Feb 2022 07:57 AM PST I recently started working with TensorFlow and I read that it turn's data into tensors.I looked it up a bit but I'm not really getting it, Would love an explanation. [link] [comments] |
| Ask Anything Wednesday - Physics, Astronomy, Earth and Planetary Science Posted: 02 Feb 2022 07:00 AM PST Welcome to our weekly feature, Ask Anything Wednesday - this week we are focusing on Physics, Astronomy, Earth and Planetary 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] |
| How can effect of electromagnetic radiation on human sperm be explained physically? Posted: 02 Feb 2022 08:20 AM PST I have been researching the question of whether electromagnetic radiation emitted from things like cell towers or wifi access points can be harmful to the human body. I have found many sources1 that state that there is no health risk. The frequencies these devices use are simply too low to pose a risk. That makes sense to me, and I have no reason to doubt that conclusion. But then I found several sources2 that referenced a Japanese study that apparently found that WiFi radiation can actually negatively affect human sperm. My question is, can the results of the study be explained using physics? What is damaging the sperm physically speaking? What am I missing? I also want to make it clear that I am not a skeptic of science in any form. I am simply interested in this subject and would like to learn something. Footnotes: 1 Sources claiming WiFi and cell tower radiation is harmless:
2 The study claiming electromagnetic radiation is affecting sperm: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4503846/ [link] [comments] |

| Posted: 01 Feb 2022 09:03 PM PST NASA's webb.nasa.gov site mentions that as the telescope cools, "[it] will be carefully controlled with strategically-placed electric heater strips." I can imagine various warpings of the frame othat might happen if the scope cools unevenly, but I'm sure that's too crude or just wrong. What are the specific failures folks are trying to avoid?

| How to extract carbon by recycling things? Posted: 01 Feb 2022 10:05 PM PST I am working on a game based in the far future when all the coal and oil reserves are used up and was trying to figure out how it would be possible to get carbon as a resource for the crafting system. I know theres talks of scrubbing carbon from the atmosphere which I may add as a slow way to get carbon. Is there any other ways of recycling things to produce carbon? Or at least a believable enough way for a video game? [link] [comments] |
| Could eradicated diseases return through means other than bioterrorism? Posted: 01 Feb 2022 07:04 PM PST Diseases such as smallpox and rinderpest have been declared globally eradicated. It is stated they could return through bioterrorism. Could they return through another means? [link] [comments] |
| Does binding energy continue to increase at smaller and smaller scales? Posted: 01 Feb 2022 03:56 PM PST As far as I know, When a large molecule like ATP releases the energy of its mechanism through hydrolysis, it can liberate almost 0.5 eV of energy. In biological terms I have been told that this is a pretty significant amount of energy for most operations at that scale. However, The chemical energy released from burning gasoline is significantly greater than the movements of the larger ATP structure-- where the combustion of a single Octane chain (C8H12) into CO2 and H2O releases almost 94 eV of energy. Compared to that, the fission of a single uranium atom releases 200,000,000 eV of energy, which is obviously a totally different realm of consideration with very different mechanisms at work. As far as I understand, this is to do with the relative difference in strength between the strong nuclear force and the electromagnetic force that governs chemical bonding, but does this trend continue further down to the quantum level? If one were able to break down or fuse individual sub-atomic particles, would the energy involved in the interactions of quarks and other small things make uranium look like gasoline by comparison?

After you have used your Android smartphone or tab for a while, it accumulates a large volume of trash in its system. This large sum of trash causes frequent freezing, lagging and slowing down of the Android system.
ReplyDeleteThis gives rise to a series of questions; how to empty recycle bin on android phone? Where are the deleted files? Doesn’t Android have a recycle bin? No. Unlike Windows and Mac computers, Android phones and tabs do not have a recycle bin.
There is nothing to be worried though. Android has its own set-up for you to find trashes and empty them without having to go through a recycle bin.
