| Posted: 16 Dec 2018 02:15 PM PST Most of my question is explained in the title, but why do superheavy elements last for so short - do they not have a stable form in which we can observe them? Edit: Thanks to everyone who comments; your input is much appreciated! [link] [comments]  |

| What determines the proportion of isotopes for an element? Posted: 17 Dec 2018 07:14 AM PST For example, Carbon. Why is Carbon-12 99% of all Carbon on earth, while Carbon-13 is about 1%. I can accept that Carbon-14 is uncommon because of its instability, but Carbon-13 is described as stable and natural. [link] [comments]  |

| Does the hydrophobicity of an objects surface affect the bouyancy of the object? Posted: 16 Dec 2018 07:09 PM PST Will one of two objects break the surface tension of water quicker if the only difference between them is their surface texture? Will one of the two sink faster afterwards? [link] [comments]  |
| Does running through the rain make you more or less dry than walking? Posted: 16 Dec 2018 06:19 PM PST Lets say I had to run to my car in the rain to grab something. Would running to my car and running back make me more or less wet than if I walked to my car and back? Certainly the time I saved by running would decrease my end wetness over a given distance, but would the additional droplets I encountered laterally while running make me more wet anyway? I imagine it boils down to a matter of how many drops of rain contact me in each given scenario, but I cannot guess which is higher. Help me reddit! fake edit: Plus there is a splash factor as well, running through thick rain would certainly make legs wetter, wouldn't it? [link] [comments]  |

| Can Light go both ways in Fiber Optic? Posted: 17 Dec 2018 01:24 AM PST Can light go both ways in a single fiber optic, does light interfere with light? Would one have to some how give each end a turn so only one end is producing light at any given time? [link] [comments]  |

| Am I seeing cosmic microwave background radiation on an ordinary spectrum analyzer? Posted: 16 Dec 2018 06:09 PM PST I am an engineering professional and I specialize in RF. I use RF spectrum analyzers often at microwave frequencies, and there is always a noise floor displayed (HP, Agilent, Keysight equipment, etc.). There's always some kind of minor variation in power at the bottom of the display. Is the noise I'm looking at part of the cosmic background? I do know it appears at all frequencies, but I was just interested to know. It's not terribly important but I would think it was incredibly cool if that's really the cause of the noise, it would link my every day work to the wonders of the cosmos :) [link] [comments]  |
| How are blocking temperatures related to TRM? Posted: 17 Dec 2018 05:45 AM PST From what I understand, Thermoremanent Magnetism occurs during cooling of igneous rocks. However, it is stated in multiple sources that a blocking temperature (or lower temperatures) causes magnetic moments to be blocked, and superparamagnetic material to lose its preferred direction of magnetization. Does this mean that Natural Remanent Magnetism in igneous rocks discontinue once cooled to normal surface temperature? [link] [comments]  |

| Are vitamin/mineral supplements ever effective? Posted: 16 Dec 2018 07:46 PM PST I am trying to do my own research on this topic, as well as ask for others' input as well. I am overwhelmed by all the opposing information out there. I want to know if it's worth it for me to buy expensive vitamin supplements to complete my diet. I know I should eat most of my vitamins, I try my best to do so, but I naturally fall short on some vitamins due to dietary restrictions like dairy and meat. I am not eating terrible food then taking my multivitamin and calling myself healthy. I just want to know if it's beneficial for me to take an iron supplement to help prevent an iron deficiency or take any vitamin/mineral supplement to help prevent deficiencies. Do these things help?

| Is there any membrane that allows gases to pass but blocks liquids? Posted: 16 Dec 2018 04:36 PM PST Looking for any kind of filter or membrane that allows gases to pass through but blocks liquids, similar to an osmosis filter. Edit: I would like to know more about the principle of work, as Im guessing the creepage distance of such membrane will allow a controlled number of atoms or molecules pass through, easier for gasses and harder for liquids that come packed in chain-like structures. To be more specific on the question, my ultimate goal is to filter out a stream containing gases that are saturated with high density liquids mostly suspended and only partially disolved. I am aware that this can be done physically with pipes specifically made to generate "jets" that push the liquids towards the pipe walls, but I don't think this works for the part of it that's dissolved within the gases. Currently I am a last year industrial & electronics engineering undergrad, so I would be very grateful for an over the top explanation and a link to somewhere I can further research. Thanks in advance. [link] [comments]  |
| Why is bismuth not toxic like the other heavy metals? Posted: 16 Dec 2018 12:11 PM PST Lead, thallium, mercury and many of their associated compounds and organic derivatives are all highly toxic to humans and yet we can drink bismuth in pretty pink liquids to help upset stomachs. What is it about bismuth that makes it not as harmful as the other elements? [link] [comments]  |

| [Medicine] Why can’t mesothelioma be cured? Posted: 16 Dec 2018 03:01 PM PST I realize my title might not make any sense. With the revelation that baby powder may have contained asbestos, why isn't there a cure for mesothelioma? What makes mesothelioma so bad that it's a death sentence? Is there any way to utilize stem cells or some other advance in medicine to combat the effects? Also, why isn't there a test for early detection? Is askscience the right place for this?

| Ageing while "time traveling"? Posted: 16 Dec 2018 03:48 PM PST I don't know much about these things but i'm wondering something. I'll try to explain what my question is as good as possible but this may be hard due to my lack of knowledge on the subject If I understand correctly there are places in the universe where if you could be instantly teleported there and spend a hour there and then be teleported back to earth, on earth let's say a year has passed (so you kind of time travelled). Now what would happen to your body when you're in such a place? Would you instantly become tired and hungry because in the first 10 seconds that has passed a day has passed on earth or would your body after the hour has passed just aged a hour? So how would your cells react is the question i think i'm trying to ask. Do they "know" time is somehow slower and adjust to this or not? I hope my question is clear and that someone can answer it, thanks in advance. [link] [comments]  |

| How do we know modern chemicals and materials aren't toxic? Posted: 16 Dec 2018 09:53 AM PST I was watching some Cody'sLab videos on mercury which got me thinking; we used to use mercury in everything, and it was only until it was discovered to be harmful to the body that we limited it's uses. Is it possible that we could someday in the future find out that a modern material used in many applications is actually harmful? Or do we have ways of being confident that this is not going to be the case? [link] [comments]  |
