How does information transmission via circuit and/or airwaves work?

Posted: 12 Aug 2020 01:38 PM PDT

When it comes to our computers, radios, etc. there is information of particular formats that is transferred by a particular means between two or more points. I'm having a tough time picturing waves of some sort or impulses or 1s and 0s being shot across wires at lightning speed. I always think of it as a very complicated light switch. Things going on and off and somehow enough on and offs create an operating system. Or enough ups and downs recorded correctly are your voice which can be translated to some sort of data.

I'd like to get this all cleared up. It seems to be a mix of electrical engineering and physics or something like that. I imagine transmitting information via circuit or airwave is very different for each, but it does seem to be a variation of somewhat the same thing.

Please feel free to link a documentary or literature that describes these things.

Thanks!

Edit: A lot of reading/research to do. You guys are posting some amazing relies that are definitely answering the question well so bravo to the brains of reddit

Why was the Tianjin explosion so much more of a fireball compared to Beirut?

Posted: 13 Aug 2020 03:05 AM PDT

Today is the 5th anniversary of the Tianjin explosion. In my mind, the 2 main explosions in China were extremely bright followed immediately by HUGE fireballs, and the recent posts verify my memory. Why was the Beirut explosion just a relatively small fireball followed by what looks like only debris and smoke shooting into the sky if it was the same type of chemical exploding?

Would a salmon still die if it was physically prevented from returning to their native river?

Posted: 12 Aug 2020 09:15 AM PDT

I've been reading the wikipedia page on the salmon run and it said that "the salmon's condition deteriorates the longer it is in fresh water," but surely the innate biological changes impact this as well? What kills them more, being in fresh water, or the reproductive stage itself?

Why do plasma balls mess with surrounding electronics?

Posted: 11 Aug 2020 08:29 PM PDT

Twice now, I've played with plasma balls (yes, those plasma balls) and during the process of playing with the plasma, electronics In the general vicinity malfunction. First it was a cell phone touch screen refusing to let me use it while the plasma ball was on. Next, it was a DDJ mixer turntable (one side, closest to the ball) refusing to work.

What is happening? Thanks in advance.

Welcome to our weekly feature, Ask Anything Wednesday - this week we are focusing on Economics, Political Science, Linguistics, Anthropology

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:

I usually play with my phone while in the shower and often the moisture detected notification pops up on my samsung note 8. I looked online but the only results are people trying to get rid of the notification whereas I'm interested in what sort of sensor or system they use to determine that the charging port is indeed moist.

What does the recent research into T cells and cross immunity of COVID mean?

Posted: 12 Aug 2020 06:22 AM PDT

I am seeing lots of information regarding this, if you have caught another similar corona virus in the past even if you don't have antibodies you may have T cells or memory cells that may produce a milder case of covid, from my understanding.

Would this also be true if you were to later contract a mutated strain of Covid? What are the implications of this, in regards to "immunity" - does this mean that it's possible that once more people get covid that at some point it may become like the common cold?

What makes a vaccine safe or unsafe for blood donation? How likely is it an eventual COVID19 vaccine will be cause for deferral?

Posted: 11 Aug 2020 05:00 PM PDT

I made a regular donation again this week, and the screening question about recent vaccinations made me wonder what determines if the vaccine causes a deferral or not. If tens of millions of people suddenly start getting vaccinated all at once to quell a pandemic, I can't imagine it going well for the blood supply if it comes with an automatic several week deferral.

Why would a bandana be less effective in reducing transmission of COVID-19 than a single layer of cotton?

Posted: 12 Aug 2020 01:40 AM PDT

In response to this study, I am curious about why a bandana would be so much less effective in reducing transmission than a regular cotton mask. The neck gaiter results make sense to me because the material is lighter and meant to be more breathable, but in the case of bandanas, most are made of cotton and then folded over in order to be worn, resulting in two layers of cotton covering a larger area in front of the mouth and nose (at least, in the way that makes most sense to me). Any ideas about this? I'm thinking maybe they aren't folding the bandana, or perhaps the bandana material is not cotton, as they don't define what kind of bandana they use.

Has anyone thought of doing this during an earthquake with a drone?

Posted: 10 Aug 2020 10:55 PM PDT

I always wondered how the earth moves when earthquakes occurred. Most videos on the internet show this with shaky camera footage moving WITH the earthquake. I want to see how the ground moves from a very stable and stationary standpoint. What if scientists programmed a drone to fly upward and immediately start filming after it detects an earthquake? This would show exactly how the ground moves side to side whilst the drone stays completely stationary giving us a very interesting POV. Does anyone know if this has been done? Can it be done?

Is monatomic powder real?

Posted: 10 Aug 2020 12:37 PM PDT

I'm trying to figure out how monatomic powder is made, or if it's even real, but every time I try to look it up it's just a bunch of new wave energy healing stuff. Apparently people sell "monatomic powder," usually gold, some ranging from 14$ to 10,000$ and all of the sellers claim to be alchemists and that it's meant to be ingested for "spiritual healing." Is that even legal to sell metal as food? Lol. Can someone explain what monatomic powder actually is and if it's even possible to make? You'd think it would be easy to google but it's not, the only results that show up are conspiracy related

Do we know how animals with ridiculously long necks and relatively compact bodies like Tanystropheus and the Plesiosaurians avoid the snorkel problem? Were their bodies just 80% lung?

Posted: 10 Aug 2020 10:45 AM PDT

Is there anything in the skeletal morphology that might give us a hint? I know sauropods may have possessed a respiration system similar to birds and not had as much of a problem as a similarly-proportioned tidal respiration animal, and giraffes have some funky stuff going on but not related to bone morphology. Do we know how would have these non-bird aquatic reptiles would have managed their respiration?

Is there any result related to typical overlaps in orbits of Lie group irreps?

Posted: 10 Aug 2020 09:15 AM PDT

Hey! So a project I'm working on lead me to the following kinda technical and niche question, I wanted to get any information on where to find an answer if it exists.

Suppose G is a compact connected Lie group, and that it acts on some finite dimensional Hilbert space H as a unitary representation. Now let g be sampled from the Haar measure on G.

Is there any result stating how large one can expect the random variable

|< v, gv >|^2

to be? (Where v is an arbitrary unit vector in H.)

When G is the unitary group and H is just the defining representation, this is typically 1/ (dim H)^2 (as in, the distribution is rather concentrated around that mean). I was wondering if a similar result exists, but for different groups and irreps.

It's also completely fine if one must impose more regularity conditions on G.

Thanks in advance!!

Why do we need hybridomas?

Posted: 10 Aug 2020 08:28 AM PDT

A hybridoma is basically a fusion of a B-cell which produces antibodies and a cancer cell. It's useful for creating monoclonal antibodies (basically, tons of identical antibodies from clones of an original cell). However, it's a labor intensive and expensive process.

Given that antibodies are just proteins, why can't we just splice the required genes into a vector (like E. coli), like we do with other lab processes?

In the sense that alcohol intoxication (and possible hangover!) is tied to the amount of alcohol consumed, is there a corresponding concept when dealing with pathogens and infection? Does greater exposure lead to more sickness? Is there ever a "safe level" of exposure, even for very dangerous pathogens (e.g. HIV, Ebola, etc...)?
