that temporary "watermark" on our vision when we look at something bright then either look away or close our eyes?
The color-sensing cone cells in your eyes need time to "recharge". When light hits those cells, special molecules absorb the light and are forced to change shape, which activates the nerves in your retina. When you stare at a bright light, your cone cells are all firing, all of those molecules are getting bent, and w...
[ "These cause permanent obstruction of aqueous outflow. In some cases, pressure may rapidly build up in the eye, causing pain and redness (symptomatic, or so-called \"acute\" angle closure). In this situation, the vision may become blurred, and halos may be seen around bright lights. Accompanying symptoms may includ...
...how do boogers form?
Lots of the dirt and dust and junk in the air get filtered through the hairs in our nose when we breath in. Once its trapped in the cilia, the hairs in your nose, your mucus membrane releases a fluid to wash them off that normally runs into your stomach. Left over bits dry out before draining into your stomach and t...

What do we know about the origins of slavery? Is there any evidence of slavery in prehistoric times?
We do know that the Hammurabi Code, our oldest known written legal code, had rules for slaves. So 4000 (ish) years ago slavery was an accepted established part of that society. That takes it back to the beginning of written history.
[ "Slavery was known in almost every ancient civilization and society including Sumer, Ancient Egypt, Ancient China, the Akkadian Empire, Assyria, Ancient India, Ancient Greece, Carolingian Europe, the Roman Empire, the Hebrew kingdoms of the ancient Levant, and the pre-Columbian civilizations of the Americas. Such i...
Upon racial integration of America's school system what happened to all of the African American teachers?

how can water be reflective and see through at the same time?
Pretty much any object absorbs, reflects, and transmits some amount of light that strikes it. Nothing is perfectly absorptive, transmissive, or reflective. This is also why objects can display colors when you shine white light on them, they're selectively reflecting certain wavelengths and absorbing others. The color y...

what the fbi is investigating on hillary and why it is so important
The FBI believes that Hillary may have kept emails that were intended to be kept secret on an unsecured home server. It's like if someone working at Fort Knox took a couple bars of gold home, and kept them in a shoe box. Even if the gold wasn't stolen, it would be criminal to expose the gold to that much risk.

Would be the dying sun ejected material massive enough to allow the formation of a smaller star, a.k.a red dwarf?
Yes absolutely. In fact this is exactly how the next generation of stars form from the previous! & nbsp; An example is the process by which white dwarfs are created. A white dwarf is the end of a small and intermediate mass stars life. If at any stage of the shell burning process the shell runs out of fuel the core ...

why does emf/induced current occur when flux and therefore magnetic fields change?
Here's the argument: it's not ELI5 but it's as close as I can get. 1) Magnetic forces from motion. According to the Lorenz force law, charges in a segment of wire will experience a force proportional to the magnetic field strength, and to their velocity. We'll take this as a given for this explanation. 2) EMF from ...
[ "To understand the origin, consider a wire loop, placed in magnetic field. According to Faraday's law of induction, if the magnetic flux is changed through the loop, an emf will be induced in this. The magnetic flux may be changed by changing the area of the loop or by changing the magnetic field. Why a changing ma...

If I set my car's AC to 72 degrees, will my car use less energy if the outside temperature is 78 instead of 90?
It would use less energy, yes. The reason is that the compressor and fans will still be using the same amount of power, but the AC will be on for shorter periods of time because the time taken to cool from 78 to 72 is shorter than from 90 to 72. The car also will absorb much more energy if the outside temperature is 90...

The mythic history of the ancient Near East - Egypt, Canaan, Syria, Babylon - is full of "magicians" and "sorcerers" going around and doing impressive things to kings and such. Were these the same sort of tricks as magicians use today, and did people of that time really take them seriously?
I can only partially answer this question, as an Egyptologist, with little experience in near Eastern cultures. However, I'll try to give you as best as answer I can from my experience. In Egypt, 'magic' was linked very closely to medicine and religion. Magicians could have multiple roles, and often used ivory 'wands'...

what determines the path that veins and arteries take through the body
The veins and arteries do follow a similar path in every body - at least the main arteries and veins do -, they teach that in med school and med students are supposed to identify them by location. You can find blood vessel maps online. The path that they take is determined by the placement of the organs in your body. ...

what is fm synthesis and what are the difference between fm, subtractive, and additive synthesis?
FM stands for "frequency modulation." In general it refers to any sort of time that we're changing the frequency of a signal. FM radio, for example, sends a signal by modulating (changing) the carrier frequency very slightly. When you tune into a radio station, the channel number is the carrier frequency at which they ...
[ "FM synthesis (frequency modulation synthesis) is a process that usually involves the use of at least two signal generators (sine-wave oscillators, commonly referred to as \"operators\" in FM-only synthesizers) to create and modify a voice.

it seems clear that subatomic particles aren't solid little spheres, what are they?
Bear with me, physicists, this is super ELI5...

why do american semi trailers have a long hood and european trailers don't?
My understanding is that in Europe (and elsewhere in the world) there are limits on how long the total length of the truck + trailer can be, so not having a long hood allows for a longer trailer length.

Why do we refer to rome (post julius) as an empire even though they never refered to themselves as such?
Well, "emperor" is the English term derived from the Latin "imperator" which Augustus did use as a title.

When does the body know to release Insulin?
Essentially, the concentration of sugar (glucose) in the blood activates the beta islet cells in the pancreas to release insulin.
