In the early 19th century, intellectuals and those well-traveled would often drop French words into the conversation to show how clever they were. They would then point out that the word they had just used was French, often to embarrass someone nearby who was less fluent in the language.
To counter this, the less well-traveled (often poorer) people would, after swearing, loudly proclaim, towards those that had previously used French in the conversation, “Pardon my French.” - The latter stuck.
It’s been proposed that your body doesn’t in fact have “wet” receptors,
but instead combines temperature, texture, and pressure to perceive
“wetness” and form a sort of “touch memory” based on that. Have you ever
worn a latex glove, then dipped your fingers in water? Feels wet, but
your fingers are dry inside the glove.

The consequences of sleep deprivation at 24 hours is comparable to
the cognitive impairment of someone with a blood-alcohol content of 0.10
percent, according to a 2010 study in the International Journal of
Occupational Medicine and Environmental Health.

Now your health begins to be at risk. High levels of inflammatory
markers are in the bloodstream, said Cralle, which can eventually lead
to cardiovascular disease and high blood pressure. Additionally,
hormones are affected — your emotions can be all over the place.

After two days of no sleep the body begins compensating by shutting
down for microsleeps, episodes that last from half a second to half a
minute and are usually followed by a period of disorientation. “The
person experiencing a microsleep falls asleep regardless of the activity
they are engaged in,” she said. Microsleeps are similar to blackouts,
and a person experiencing them is not consciously aware that they’re
occurring.

Expect significant deficits in concentration, motivation, perception,
and other higher mental processes after many sleepless hours, Cralle
said.
“Even simple conversations can be a chore,” noted Kelley. This is when
the mind is ripe for hallucinations. Kelley recalled a time he was on
guard duty and repeatedly saw someone standing with a rifle in the
woods, ready to sneak into camp. Upon closer inspection, he determined
he was actually looking at a branch and shadows.
You still have to pay a licensing fee to the songwriter to record a
cover. However, there’s a clause in copyright law that provides for a
“compulsory license” for recording covers, which means that the
songwriter isn’t allowed to refuse, and the fee that you have to pay is
fixed.
Two people have answered that the pyramids are “incredibly complex”- they aren’t- they’re giant piles of rocks, with narrow shafts and a few small rooms inside. We know about those because the shafts reach the surface. There may be other rooms, but it would require tunneling through tons of rock to access them, because there are no doors or hallways to these rooms, and millions of tons of rock on top of them.
Take two pieces of metal and put them very close to one another. Then heat one of the pieces of metal. The resulting temperature difference between the two pieces of metal generates a very small electric current.
Voyager 1, 2, Cassini, Galileo, Curiosity, and New Horizons use a small pellet of Plutonium to create this heat difference. The radioactive decay is what generates the heat. It doesn’t provide very much electricity but is extremely long lasting.
There are several different types of touchscreens. The two that you’re probably most familiar with are resistive and capacitive.
Resistive touchscreens, which are used in Nintendo’s products and pre-iPhone PDAs and smartphones have flexible plastic screens. When you push on the screen, you squeeze multiple layers together and this completes an electric circuit.
Most modern smartphones use capacitive touchscreens. These touchscreens are made of glass. When you touch the screen with your hand, you distort the electric field in the screen and it can measure where that change took place. Insulators, like plastic or most fibers, won’t distort the field so the screen won’t recognize them. “Smartphone gloves” have metal fibers woven into the fingertips to make the screen notice them.
