I tried it on either side of me, high and low, and it still did that. This was about 3:45 in the afternoon when the sun sets at like 5:15.
Like the title reads, why can't the public reverse-Google an unknown phone caller's number and actually get good search results or an indication of scammer/ sales/ first time caller? Please ELI5.
This is applicable to viral and parasitic infections too I suppose. The body needs to expel the pathogen, but why can't that be done with solid stool? Why does it require the stool to be liquid? Why does the pathogen change the normal consistency of stool from solid to liquid, and what expulsion property does solid stool lack that doesn't make it the natural mechanism for excreting the pathogen?
There was heavy fog this morning with below freezing temperatures. All of the trees looked like they had spikes on them (all made out of ice). How did they form so perfectly? Here’s a picture
How do people lose all their savings by doing options trading?
I've looked up options, but don't really understand it. How do you see people losing their entire account doing it, how do you avoid that (other than not doing options), and why do people call it gambling?
I read that wool can simultaneously keep you warm but be breathable and keep you cooler when its hot. How on earth does that work if your body temp is about the same regardless of how hot or cold the outside is?
What IS instinct? What exactly gives certain organisms the sense to do something? Like for example, the cuckoo bird. a cuckoo bird could be a literal BABY and just born, yet it has the instinct to push the other eggs out of the nest. (I apologize for my english or if I used the wrong words)
I want to visit my grandkids grandkids grandkids. It's my understanding that the closer you get to the speed of light the slower time moves for me while it stays the same from everyone else's perspective.
Is it theoretically possible then to travel on a near light speed vehicle and come back hundreds of years in the future for Earth?
It seems like that shouldn't be possible. I think in terms of time zones where if I'm flying across the world, it may only be 8 hours to me but I'm now ahead from my original destination by say 8+10 hours. When I fly back that time change has vanished. I'm sure that understanding is flawed as we move to subjects like huge gravitational forces and incredible speeds from great distances but I would love to better understand Einstein's theory.
An appeals court today ruled TikTok can be banned. Somehow I don't think it's any more dangerous than any other Social Media program or web browser that scrapes our data. What makes TikTok so extra dangerous it's considered a national security risk? Am I missing something, since over 175 million Americans use it?
I was under the impression that closing the valve should turn the heat off, but instead I just get hot periods and cold periods. Why isn't the heat off all the time when the valve is closed? Does it really have to be fully open or fully closed? How does it actually work?
Thank you
ETA: radiators to heat a house, not in a car, and these have manual valves.
I have an array of solar panels on my roof. How does my electricity get calculated. For an example.
November I was billed for 650 kWh by my electric company. Solar said I generated 250 kWh
Did I ultimately consume 900 kWh for the month of November?
I was replaying Mass Effect and noticed how depending on how you face you can hear the news. How does it know whether to play out of the right, left, or both speakers?
If everyone is allowed one carry-on and one personal item, why is it some times the last people in line have to have their carry on bags checked?
In PGP why do you sign a person's public key and what does their "Trust" level mean?
I always see videos of ballet dancers destroying their shoes. Which I understand is because they are modifying them to make them better to dance in and more comfortable, supportive, etc. but then they say that the shoes don't last them very long anyway. I guess I'm just confused why better ballet shoes aren't produced that don't need all of that modifying? It seems like that would be less wasteful and better long term?
I see 2d platformers, strategy games, first person shooters and more with the same "made in unity" logo in the corner. How does this work? What exactly is unity?
From my understanding, a terministic screen happens when it’s impossible to describe all aspects of an object using just one word, so whatever term you come up with for it will leave out some aspects and emphasize others.
Here’s my example of what I think a terministic screen is:
You have a character who’s a pink elephant with ice powers and a brave personality, and you need to come up with a name for them. Do you name them Pinkers, Trunky, Frosty or Courage?
Would my understanding, and the example, be correct?
Like cookie clicker for example. How does it still play the game even after I closed out of it?
I know that at a grass-roots level, data is represented using binary, where 1 means 5V and 0 means 0V. But this 5V must come from somewhere, right? If I turn my laptop on, the battery must be creating this potential difference. But if I turn my laptop off i.e. no power goes through the battery, shouldn't all the bits reset to 0 and all data is permanently lost? Thanks in advance
I would like to better understand what someone is trying to accomplish when practicing. Whether that's singing, instruments, sports, etc.
What do you go into the practice trying to accomplish that day? Do you just try to do it over and over again? And if so, how does that help you?
How do these small practices contribute to larger improvements?
Please explain like I'm five.
