| How do you account for a large numerical disparity between two groups when doing opinion polling? Posted: 24 May 2020 03:19 AM PDT To preface: While this stems from the ongoing unpleasantness, this is not a political thread and I'm not seeking political feedback. There was a poll done recently about public opinion re: wearing masks but someone pointed out that this paints a false picture in that it makes it seem like there are two more or less equal groups on either side of the issue when that hasn't borne out with other research done specifically on that idea. How does statistical analysis, and more specifically this sort of polling, take into account a large disparity in the actual number of pro/con respondents? In terms of answer complexity, please assume that I'm functionally five years old when it comes to math. I'm mod of /r/dyscalculia for a reason. [link] [comments]  |
| What is the average for short-term memory sentence recall? Posted: 24 May 2020 05:21 AM PDT I tend to underline the key points of the books I read, and immediately write them down in a notebook from memory. I struggle with sentences longer than 20 words. I always reread after writing to detect any possible mistake that I may have made, then I add corrections in red when needed. After I while, I can see that I have no corrections in sentences up to 21 words. But every single sentence with at least 30 words has something in red: a comma, an inverted order of terms, the use of a synonym instead of the original word... How dumb am I compared to the average foe? Thanks! [link] [comments]  |

| Posted: 24 May 2020 06:49 AM PDT I tried to search in the internet, but I can't find an explanation that I could connect to what I know (school level chemistry + quantum mechanics course from university). [link] [comments]  |
| Posted: 23 May 2020 10:01 PM PDT Just noticed this - the lenses of my glasses were totally indistinguishable from the plastic frames or my hand holding them. The shadow on the wall looked equally dark for all! What gives? [link] [comments]  |
| If a planet spins faster does the altitude of its geostationary orbit drop? Posted: 24 May 2020 05:29 AM PDT And as a follow up question: would this make it easier or more difficult to build a space elevator assuming that the planets mass remains the same? [link] [comments]  |
| What are the deciding factors in the altitude that a plane flies? Posted: 24 May 2020 04:47 AM PDT In these days of ever increasing economical efficiency, what are the main factors taken into consideration when determining the most fuel efficient altitude to fly? Why is it 30,000 feet instead of 20,000... 10,000... or 5,000? Surely it takes a relatively large amount of fuel to get the plane 1,000 feet higher in the air. So why do they fly so high up?

| Can human sweat transmit viral infections? Posted: 24 May 2020 03:05 AM PDT My wife and I enjoy watching cooking shows and are sometimes grossed out by cooks dripping sweat in/on their stations. Is our grossed out reaction unfounded? Are we just overlooking that cooked food is cooked? Are viruses transmitted via sweat? [link] [comments]  |
| The Doppler effect. Does it change a sound's pitch, or does it change the sound's speed? Posted: 24 May 2020 02:35 AM PDT If say a siren is passing by, and is changing in pitch (a two tone siren, or a oscillating siren sound) would the oscillation, or the frequency the two tones change at change also, or would it just be the perceived pitch?

| How hot is the interstellar and intragalactic space in dense galaxy clusters? Posted: 23 May 2020 07:48 AM PDT It seems to me that the space within these galaxy clusters would be that much higher because of the energies involved. Could life as we know it exist there? [link] [comments]  |
| Can flow cytometry be used to study the cell cycle? If so, how? Posted: 24 May 2020 01:14 AM PDT |
| How do you measure the brain’s processing speed? Posted: 23 May 2020 09:21 PM PDT How do you measure the brain's processing speed. Is there some reliable/trusted test. If so can you link it. I am dumb so i need it. [link] [comments]  |
| Do cats get joint problems as often as humans? Why or why not? Posted: 24 May 2020 12:45 AM PDT I thought of this question while browsing /r/noodlebones. Also, I've always been amazed by cat's ability to run and jump well into old age (by cat standards). [link] [comments]  |

| Don't antibody tests need to detect multiple configurations of antibodies? Posted: 23 May 2020 12:43 PM PDT I'm under the impression that multiple antibodies with different binding site structures can be made by different people for the same pathogen. Every piece of literature I read refer to "the antibody" for a certain pathogen like it's some kind of singular monolithic thing, where in reality I think antibodies for a certain pathogen are actually pluralistic things with a certain degree of variability? There is no "antibody." There is no "the antibody" for SARS-CoV-2. SARS-CoV-2 for instance can have multiple unique areas on their protein structures in which multiple different antibodies can be generated, so one recovered patient can have slightly different antibodies compared to another recovered patient, but both of their antibodies will still bind to different unique areas of SARS-CoV-2. There are even companies that have whittled down numerous different antibody candidates to a few that have especially high neutralizing abilities against SARS-COV-2, the point being that multiple different antibodies can bind to one pathogen. So when people talk about an "antibody test," what are they talking about, exactly? Does the test actually detect the presence of multiple different antibodies, all of which have demonstrated binding effects with the virus? Or do the tests only detect one specific configuration of antibody, and can miss other antibody configurations, resulting in a false negative (the patient actually had been infected and did produce antibodies, just not the ones that the test is specific for).

| What are the effects of CBD on REM sleep? Posted: 23 May 2020 10:22 PM PDT From what I know, THC has a negative effect on sleep cycles and kills REM sleep. Does CBD do the same? [link] [comments]  |
