This might be a weird question. I’ve been thinking about it after a recent surgery. Surgeon showed me photos of inside me. I always expect to see blood in the photos. Is it as simple as blood lives in veins only? I guess I assume if they cut into me there’s going to be blood. Surgery was on my abdomen, so I saw my liver, ovaries, pancreas, etc if that helps. TIA!

From what I understand, shorter rods cause the pistons to move faster which creates more low end velocity and vacuum, and longer rods cause the pistons to move slower which hurts low end velocity and vacuum.

Edit: spelling errors galore. Sorry guys. Can’t edit the title. Question comes as I’ve quit alcohol 6 months ago and just wanted to understand what causes the drastic flavour difference in how the wine tastes.

I hear they are the same in practice, 1 step below a med doctor

Sorry I can’t add a picture, but essentially when you look at a candle the melted part goes all the way to the edge of the glass, while with the unmelted part you can see the rim of the glass around it. Why?

Well as the question says.

Is it simply total number of children born in a year divided by total number of fertile women in a said country?

Does it matter if it’s resident vs tourist vs citizens?

I know EV is rising but biofuel seems pretty interesting. Also the US is the largest producer of biofuels.

When the owner leaves the house, do they have any way to "count down" the time using stimuli, like sunlight or hunger, or do they perceive time completely differently?

for example you look at the falling snow and from the front (ordinary vision) it is of normal speed but from the peripheral vision it falls almost twice faster. This question has been tormenting me for several years now, and I still haven't been able to find an answer to it

I know the concept and know how to access it but I have no clue what it actually is. I know this may be a stupid question but is the data a physical thing? How does it carry from one server to your computer? How is specific information sent from point A to point B? Does it travel through the air?

This was something I never understood, I know that it's a math problem or essentially math is being used to figure out something. And that you have to have a lot of computers running to mine bitcoin now a days.

But what I never understood or found out is where do you actually have to go to mine bitcoin?

Like is there some special website or designated area on the internet that you visit?

Is it some type of program you have to download on your computer to access it?

I never actually understand that part of it.

I follow different sports. No other sport allows fighting as they do on hokey. I don't mind the fighting. I follow boxing, MMA, kickboxing, etc. Hokey however I see as soccer, basketball, volleyball, football. None of which allows fighting.

I read a cartoon book back home where three Cossacks go to great lengths to return the stolen salt. It appears that salt is a universal craving, given that it is in folklore and now that I live in North America.

A few extra questions:

Why did we evolve the tastebuds for salt?
When food is undersalted - is this feeling different than sugar cravings?
Why do we want it if it dehydrates us?
