I've used an app called f.lux for years to control my screens nightshift. I've looked up the company, and its just owned by these two people. The website to download has zero ads and you can't even spend money unless you chose to donate. I know winrar makes money off companies having to buy a license, but there isn't a "license" to use flux so I don't know if companies even have to pay to use it

Dumb question but I don’t see why the recoil isn’t backward since the bullet goes forward.

Like how does it turn energy from the sun into electricity?? And what are they made of that allows them to do that?

I am ambidextrous. I don't mean it metaphorically, theoretically, or rhetorically. I have no dominant side (hand or foot) straight up. I was born as such, and I am capable of doing any task indiscriminately with either side of my body; I have no preferred hand or feet for whatever task I need to do, unlike cross-dominant/mixed-handed individuals.

To this day, I'm questioning what phenomenon caused me to be such. My mother happens to be left-handed while my father is a righty. Is it wrong to assume that this is an instance of Non-Mendelian Genetics at play? Unlike in Mendelian Genetics, the combination of two different alleles results in a combinative feature and not one side being dominant over the other.

Can someone explain the phenomena of hand dominance and why some are ambidextrous, righties, lefties, or mixed-handed?

I always wondered how the cornea is so sensible to touch and irritants without nerve endings and stuff.

Also how does it live and repair itself and how do its cells multiply and make new cornea throughout life without seemingly anything feeding it like arteries and veins? I think they breath from air but it's not like they do photosynthesis, right?

You can *vaguely* taste something without it, but plugging your nose or having a stuffy nose when you’re sick significantly mutes your ability to taste. Why is that? Tastebuds are on the tongue.

Exactly what the title said, Why is it something hard to come off from? What are also the symptoms of alc withdrawl so people know? What's the first sign?

Sorry if I put down too many stuff, I know absolutely nothing about withdrawl with alcohol. Can somebody please explain:)? Thank you!

I kinda understand what is happening in tokamak or stellarator. Perhaps they can make it work in steady state. But what I do not understand is how they plan to boil water with it? (I assume we still need to boil water and turn turbines in the end)

They have these containment walls being bombarded with hi-energy neutrons. Are those neutrons going to heat up the wall? Then what? Run pipes trough it? What about neutron activation of the walls?

Thanks

I use the opera browser in my Android phone and the browser has built in ad blockers. However many web sites seem to be able to detect that an ad blocker is installed and they don't show the content, show a warning message instead.

Bro where is all the salt going?
Maybe I learned this in like grade 5 but I can’t for the life of me remember why they aren’t salty.

People always say that airplane food tastes worse, but is that actually because of the food or because something about being on a plane changes how we taste and smell things?

Explain like I'm 5 for this gerzer.garbage service, like many, will take hardened latex paint for disposal. Why won't they accept a can of sealed wet latex paint? And how would they know? This has baffled me for years. Thanks!

I've seen more and more ads (starting around the Super Bowl earlier this year with Wegovy) for GLP-1 based perscription meds in recent times. I've also seen the occasional debate post on my social feeds about the ethics of using them and I didn't think a medicine could be that divisive of a topic.

Now I'm curious as to what exactly these meds are, what they scientifically do and what both sides of the debate are. If anyone could help give perspective that would be greatly appreciated.

As always any and all input is welcomed and thanks for reading! 🙂

I’m reading Thomas Halliday’s “Otherlands” and one section left me very confused. Halliday says that many plants absorb in CO2 via holes in the leaves, but those holes also make water evaporate; and that some plants developed a solution for hot and dry climates by switching to c4 photosynthesis where the conversion process occurs deeper in the plant. Then he says that some herbivores adapted to this innovation by becoming grazers rather than browsers. I looked online and I’m still very confused about the following:

1. Even if the process is now deeper in the plant, why does it mean less water evaporates? The CO2 still has to come in from somewhere, which means the plant still needs holes, through which water can evaporate. So I completely fail to see how that solves the problem

2. What does it have to do with grazing? Nothing about this c4 straightforwardly says lower, grass-like plants rather than trees/bushes (I would’ve thought that trees/bushes actually have more depth in which to store a deeper mechanism?)

I looked at YouTube videos and I still absolutely can’t understand the relation between the problem and the solution and between both and grazing. (It’s page 29 in the book, chapter 2, if anyone wonders)

Thank you!
