| My toothpaste contains something called "liquid calcium". What is liquid calcium? Posted: 11 Jun 2018 03:24 AM PDT From my limited chemistry knowledge, I think its pretty obvious that calcium does not exist as a liquid in standard conditions. I'm guessing that its simply dissolved calcium, which I think is a good thing to have in toothpaste. The sperg in me finds it perplexing that this toothpaste brand has "NEW FORMULA CONTAINS FLUORINE AND LIQUID CALCIUM" as the main selling point. I keep picturing some dude brushing his teeth with molten hot calcium. Of course I could be wrong, just like science intended. [link] [comments]  |

| Posted: 10 Jun 2018 05:24 PM PDT I've seen on a lot of medical dramas (I know that they're not always accurate though) that blood bags are kept in coolers. But when the doctors put the blood into a patient, is it warmed up? If so, is there a specific tempature it needs to be at? [link] [comments]  |
| Is overcharging a thing and how does it work? Posted: 11 Jun 2018 02:49 AM PDT When it says charge this device for 2 hours. If I charge it for 6 will the battery life of the device shorten? If so how does this happen? [link] [comments]  |
| Is it still possible to discover/create a new element? Posted: 11 Jun 2018 08:20 AM PDT I know about the existence of nuclear transmutation and decay, and that those can transform an element into another, but is it possible to accidentally, or purposefully "create" a new element? Or is it possible that there are elements that we haven't discovered yet? [link] [comments]  |

| Posted: 10 Jun 2018 06:35 PM PDT I know that wave impedance is defined as the ratio of the transverse components of the E-field and the H-field. I also know that the characteristic impedance of a coaxial line can be simplified as the square-root of the ratio of inductance (L) and capacitance (C). I know that inductance is related to the amount of energy stored in the magnetic field (H). I also know that capacitance is related to the amount of energy stored in the electric field (E). And I'm familiar with the circuit topology used to represent a transmission line. I just can't help but wonder if there is more to these two relationships and that these two must be tied together in some intrinsic way, but I lack the intuition, energy, creativity, etc. to see what such a connection would be.

| How do we get so much information from gravitational waves? Posted: 11 Jun 2018 12:46 AM PDT So one issue I am having trouble connecting about gravitational waves is how we get some much information from a seemingly simple (though incredibly precise) measurement. Let me explain how I think it works and you folks correct me as needed. For all I know, I'm way off. My idea is that one big difficulty in astronomy is knowing where to point our telescopes to see the more fleeting events like supernovas and joining black holes and such. There is a lot of space and only so many massive telescopes, we can't watch everything all at once. What LIGO is doing is telling us where to aim our telescopes using something similar to finding the epicenter of an earthquake. When the detectors get hit, we triangulate the measurements giving us a precise direction to look in. We aim our telescopes and BOOM! We see two black holes merging. Something we would have missed if we were just scouring the sky manually. Not to mention, seeing the event proves that LIGO is working, because if it was a bad reading we would have looked and seen nothing out there. So /r/askscience. How far off am I? [link] [comments]  |

| Are solar panels in hotter places more efficient than solar panels in other, cooler temperatures? Posted: 10 Jun 2018 08:32 PM PDT By hotter places, I mean surface level temperature and the temperature you see on the weather Does it even make a difference ? If so by how much? [link] [comments]  |
| How are electric fields generated inside a particle accelerator? Posted: 10 Jun 2018 04:53 PM PDT I know that electric fields are required to strip the electron off of the hydrogen nuclei, but could no reference as to how these electric fields are generated.The searches kept feeding back to electromagnetic fields and static electric fields.
