| Is it easier to accelerate at higher speeds? Posted: 23 Jun 2020 08:00 AM PDT I've done some googling but seem to be getting mixed answers. I was wondering if it would require less energy to gain speed when you are already travelling at high speeds than it would take to increase speed the same amount but if you were going slowly or not moving at all. For example would a 5kg rock need more energy to increase speed by 10m/s if it already travelling at say 50m/s compared to if it was only moving at perhaps 5m/s? [link] [comments]  |
| How did people make programs for programming without programs for programming in the first place? Posted: 22 Jun 2020 02:52 PM PDT I mean, at first there were basically computers which were machines for counting numbers, and then, all of a sudden, people created stuff to write code. How'd they do it? [link] [comments]  |
| Posted: 22 Jun 2020 01:06 PM PDT Stink bugs, spotted lantern flies, kudzu plant, asian carp, lion fish, etc, etc. Seems like we are being taken over here in the US with all of the invasive species from other continents. What I am curious about is where other continents have to deal with any invasive species from North America? The only one I remember reading about is raccoons in Germany, but I hardly see trash pandas as invasive and displacing/threatening native species. [link] [comments]  |
| What do you call someone that studies geysers? Posted: 22 Jun 2020 07:39 PM PDT I know this is silly but it's turned into a rabbit hole. Best we've come up with is geologist but there seems to be sub fields of EVERYTHING else in science. I've googled this for an unreasonable amount of time. Please help me and half my family who are now very annoyed. [link] [comments]  |
| Posted: 22 Jun 2020 09:10 PM PDT I have a Keepsake jar and instead of sand or something to fill and place my keepsakes on, I use Rock salt, I like the look of it and it's easy to place things in it to keep it up. I had a stone that I got in a river on a trip and I put it in the jar. Now the rock was originally Fog Grey, but after being left in the sealed Jar over night the rock turned Tar Black. I tried washing it off and it didn't work. So now I just have a Black stone. I don't mind it, I just wanna know what happened. Why did this reaction occur? What was it that caused this? P.S. I wasn't sure what post flair to use for this so please forgive me. [link] [comments]  |

| Posted: 23 Jun 2020 01:42 AM PDT I've been reading recently about how North Africa goes through a pattern and through dust and pollen records suggests for the 'African humid period'. From my understanding, the dust which is carried across the Atlantic carries nutrients and contributes towards the growth of plants in the Amazon. With the Sahara being green, would this have had large scale impacts on the growth and nutrients in rainforests? [link] [comments]  |
| Posted: 22 Jun 2020 12:11 PM PDT Are there any drawbacks that cancer growths have (for themselves not for the host) as a result of this uncontrolled proliferation? [link] [comments]  |
| Posted: 22 Jun 2020 02:55 PM PDT Further, does this fluctuation have any adverse effects? Given the finite size of this planet, would there be an ideal population size? I'm sure there's plenty of room with how we are currently building upward and the eventuality of humans developing outward into the ocean. Before those next advancements, I'm curious. These questions stem from recently reading discussions involving global fertility rates, global temperature increases, the continued spread of disease, and an alleged increase in deaths resulting from a natural disaster. Thanks in advance! Note: Repeat submission due to not flairing the post, as per the rules. Anthropology seems to fit, and I'm curious what folks who work in that field have to say in response to these questions. [link] [comments]  |
| Is there a way to predict half-life? Posted: 22 Jun 2020 07:35 PM PDT Is there a way to predict an atom's/nucleon's half life just based off of the proton to neutron ratio? Answers from any field of science will be appreciated (Before the mods have my head, Google cant seem to comprehend my question, either that or I'm just shit at articulating😂😂😂) [link] [comments]  |
| Why does heavy water have a higher boiling point than regular water? Posted: 22 Jun 2020 08:48 PM PDT I learned at school that the forces and interactions between molecules decide the boiling point of something. If other conditions are the same between D2O and H2O, the London dispersion force should be the reason why D2O has a higher boiling point.(since its strength is often said to be affected by molecular mass) However, from my understanding, the reason why the London forces are stronger for heavier molecules is because they tend to have more electrons. According to this logic, London forces don't seems to be able to explain the difference in their boiling points either. If so why does heavy water have a higher boiling point than regular water? Does this also happen to other molecules with different isotopes? [link] [comments]  |
| Posted: 22 Jun 2020 10:02 PM PDT As I understand it there is a thought experiment that basically says that if you are in a room, there is no way to tell if you're acceleration "downward" is due to gravity or the room itself is accelerating. A consequence of this is that if you shine a laser at a wall the photons will impact the wall at a point "lower" than where it would with no gravity or acceleration. So my question is, couldn't you measure that acceleration at two different points along the normal of the "floor". In gravity you would get two different results as the point father from the center of the gravitational mass has less acceleration. In the scenario where the room is accelerating the results would be exactly the same. And thus in the laser experiment, the point of impact in the room with gravity would be just a tad "higher" than the room acceleration one? Is this logic sound? [link] [comments]  |
| What is the evolutionary advantage of viruses killing their host? Posted: 22 Jun 2020 05:13 PM PDT An ideal virus in my mind would be one that causes symptoms that allow it to be transmitted (sneezing, coughing etc.) but doesn't get bad enough to where those infected would either voluntarily isolate themselves or be too sick to go out whether they want to or not. This worked well for the common cold considering it's prevalence. What is the point of viruses such as Ebola which realistically would never become as widespread as the cold or covid due to its severe symptoms and its high mortality which would likely fear monger people into being strict about isolation? Are these viruses very lethal just because they are not in the right host and the new host can not tolerate them as well? This makes it seem as though there is no real reason for viruses to want to kill anybody and it's more an accidental result. (Or of course viruses don't have brains and can't really gauge when enough is enough) [link] [comments]  |
| How does salt water oral rinses increase mouth pH? Posted: 22 Jun 2020 08:58 PM PDT Several online resources describing the benefits of oral salt water rinses mention the increase of salivary pH (more alkaline) as the means to inhibiting/slowing bacterial growth. However these sources do not describe the chemistry of how salt water increases oral pH. NaCl doesn't change the pH of water so is it reacting with something else in the mouth to neutralize acids?

| What makes non-inertial reference frames special? Posted: 22 Jun 2020 10:26 AM PDT I mean, you can't apply Newton laws on NIRFs, but what makes them different from an inertial reference frame? Let me explain: consider an IRF and a NIRF that moves with acceleration A with respect to the IRF. Shouldn't we be able to say that, from the persepective of the NIRF, the IRF is accelerating with acceleration -A? Therefore, what makes the NIRF difrferent from the IRF that prevents Newton laws from working? (IRF: Inertial Reference Frame; NIRF: Non-inertial Reference Frame) [link] [comments]  |

| What caused the abundance of rivers in the Congo Basin? Posted: 22 Jun 2020 10:50 AM PDT I am currently reading "King Leopold's Ghost" which outlines the colonization of The Congo Basin. One of the chapters states: "it's fan shaped web of tributaries constitute more than seven thousand miles of interconnecting waterways, a built-in transportation grid rivaled by few places on earth." What caused this abundance of rivers? We're they man-made, or were they a product of a geological event? Why are there so many rivers in the Congo? [link] [comments]  |
