Why is there a soup spoon in the forensic tool?
Why is the last 1% of the phone's battery so durable?
Why do terracotta warriors and horses have single eyelids?
Welcome to this episode
Five of today's most interesting trivia
01
Five fingers
Why is there only a "ring finger" without a name?
This is mainly because:
The ring finger is "so useless"!
In ancient times
The ring finger is also known as the "second finger" and "second finger"
Because everyone thinks
The ring finger is the least useful
Needless to say, thumb and index finger
The status and importance speak for themselves
The middle finger serves as the longest one
It is very important on some special occasions (quarrels).
The little finger is small and flexible
Picking the nose and picking the ears is indispensable
Only the ring finger
Basically useless
So I don't even have a name
Other than that
Let me add a knowledge point to you
How did the name of the index finger come about
The statement of the index finger
It first appeared in the Spring and Autumn period
It's about a person who is about to eat something good
The index finger moved involuntarily
Take the name index finger
It means to see something delicious
Shows the appearance of greed
The idiom "index finger moves".
That's how it came about
02
Grilled fish at a fish shop
Why are they basically 2.8 pounds?
This question
It can be analyzed from three angles
First of all
It is a matter of profit for farmers
There are quite a few fish species
They can all grow to ten or twenty pounds
But in terms of earnings
It's not that the heavier the fish, the more profitable it is
After deducting various costs
All in all
2-3 pounds is the most profitable weight
secondly
It's a matter of the taste of the grilled fish
2-3 pounds of fish
It tastes the best when made
It has both a burnt aroma and a feeling of hypertrophy
At last
It's a "routine" in marketing
2.8 pounds of grilled fish
Generally, it corresponds to a meal for 2-3 people
2.1 catty, 2.2 catty
It can create the impression that "not enough to eat".
If you exceed 3 catties, you will have the feeling of "not being able to eat".
03
Forensic toolbox
Why are there soup spoons?
First of all
It's for when there's a need
Scoop out fluids, blood, and so on from the corpse
There are so many organs in the abdominal cavity
If the deceased died of excessive blood loss
A lot of blood may accumulate in the abdominal cavity
The size of the ladle with a long handle is fixed
It can be done without damaging the organs
A measured amount of blood is removed
Facilitate subsequent laboratory tests
Other than that
It can also be used to scoop out
There is nothing in the stomach that has been digested
Scoop it out and put it in clean water
It's easier to tell what's there
04
The last 1% of your phone's battery
Why does it last so long?
Because the phone shows
"Remaining Battery"
It is not the actual remaining charge of the battery
Accurately detect the remaining charge of the battery
Technically, it's still more difficult
The "remaining power" that we see
In fact, it is only a speculative value
manufacturers at the time of design
Will make the phone show "1%" earlier
This reminds the user to charge as soon as possible
Avoid a complete shutdown of power
Other than that
Some phones will be on low battery time
Automatically enter the power-saving mode
This will also make the final "1%"
Becomes particularly durable
05
Why are terracotta warriors and horses all single eyelids?
There is no exact answer to this question
At present, there are many opinions
There are several mainstream theories
First, ethnography says
At that time, the northwest region where the Qin state was located
It belongs to the East Asian Mongolia race
Most people are born with single eyelids
Second, fade said
It is thought that there are both single eyelids and double eyelids
But the double eyelids are painted with paint
Oxidative shedding after excavation
It's all a single eyelid
Third, the image says
It is believed that single eyelids are more sharp
More in line with the image of a soldier
So they all made a single eyelid
These are the above statements
Which do you think is more convincing?
All right
That's all for today
We'll see you next time~
Doctor for a minute, his posture rising
