Why is it that I am not able to read a book without moving my eyes if the entirety of the page is within my field of view? Why do I have to center my eyes on an object to observe it fully? And why is it that I am still able to view changes in surroundings in the edges of my field of vision despite there being supposedly no way...
We know what causes magnetic fields and we know what their effects are, but what actually are they? What does it mean for them to be composed of “lines of force”? What is the mechanism of that force? What is actually going on in a magnetic field that the space outside of a magnetic field lacks?
And how old are the oldest bones?
I’m thinking of things like heliocentrism where there was some modern discovery or revelation by science that invalidated a common assumption prior....
The moon rotates once per revolution around the Earth, but that’s not a coincidence. Somehow the rotation and revolution are connected to each other. Some force is keeping them the same. How exactly does that work?
I really enjoy videos about science, but they are getting harder to find on modern platforms. Is there a community out there dedicated to discussing and recommending good content regardless of platform?...
I mean, I’ve heard that you can typically only survive about three days without water, but what exactly causes your body to fail when you dehydrate too much?...

Me and the fiance we always fight about the A/C or dehumidifier. For me coming from central Europe, as soon as the humidity goes over 65% I’m sweaty and hot and can’t get dry, I hate it. She as a Korean seems never to sweat at all and even when the humidity is at 80% she seems to have no problems and thinks running the A/C...
I remember reading somewhere that mathematical symbols make up an “incomplete” written language (or something like that). I commonly formulate problems, or complete sentences using only mathematical symbols. From a linguistic perspective, what separates mathematical symbols from “complete” writing systems?
Greetings, everyone!...
Some people suggest the idea of a multiverse with each universe having a unique set of laws of physics governing it, but not many delve deeper into this. I was wondering if it was even possible to imagine a universe that is different to ours in this regard....
I want this place to succeed and grow, so let’s get active!
Landfills have been around for a long time now, and some of them get quite large. I know seagulls are changing their habits and living off landfills, but are there any other interesting ecosystems forming around them? Maybe some new microorganisms we haven’t seen before?
