What If Zero Disappears for a Day

What If Zero Disappears for a Day

What does zero mean to you? Me? Well it was a familiar grade when I got my
homework back from the teacher! But, do you think it’s just “nothing”? Yeah, me too until I realized what our world
would look like if you took away zero just for a day! And if you like a good math challenge, stick
around till the end to help me solve the most impossible task out there! – A World Without Zero You might be surprised to learn that zero
hasn’t been around forever. Yes, we used to live in a world without it! Well, an understanding of the concept of zero,
at least. It was invented in India during the 5th century. And here, it’s closely connected with the
ancient culture of this region: Nirvana is what they call absolute calmness, the absence
of anxieties and desires! So, they came up with a circular symbol denoting
this “nothing.” They called it “shunya.” The image of zero itself symbolizes the life
cycle or, as it’s also called, “the snake of eternity.” Yes, for them, zero also meant infinity! (We’ll come “full circle” to this idea
later on!) This new revolutionary concept was eventually
picked up by the Arabs and included in their numerical system, which we all use to this
day. But why did it take humanity so long to understand
something as basic as “zero”? Well, think about it: it’s not exactly something
you can observe every day. You can see those 3 birds perched on a tree
branch or those 2 bees flying around your 1 can of soda. But zero? The absence of something? You never see it, never think about it because
it’s not there for you to perceive! Yet zero is so incredibly important… – Life Today Without Zero We’ve come a long way since the 5th century. Like 16 more Centuries. Zero now has countless uses, and a modern
world stripped of this basic concept would look very different indeed… Your first thought might be that we could
no longer count higher than 9 or lower than 1. I mean, 10 has a zero in it, right? Sure, there would be no counting, but “no”
means NONE! Fractions, like .804, are lower than 1. And 9.01 is higher than 9! The entire system of counting and measuring
would break down without zero. From there, you can say goodbye to computers! All your social media, online games, YouTube
videos – you won’t get to enjoy them in this zeroless dystopia. The foundation of any computer program is
binary code. And this code consists of zero and one. While you’re at it, forget about TV, charging
your gadgets, reheating food in the microwave, even just turning the lights on! (Oh, wow, we’re already in the Dark Ages? That was quick.) Without zero, we couldn’t calculate electricity. No more Bond movies or cinemas for that matter. Movie theater projectors work by showing 24
frames per second – you’ve gotta count that from zero! Hey, look on the Bright Side! Like we’re always telling you to! cNo more
stepping on that scale and hoping the number will magically go down on its own! Clothing sizes and counting calories won’t
exist either! On that note, how will doctors do physicals? There won’t be an understanding of height
and weight. All that electronic equipment in hospitals
wouldn’t work either. MRIs, X-rays, electrocardiographs – we wouldn’t
even be able to count a person’s pulse rate! Without zero, there’d be chaos with transport. You wouldn’t be able to fill up your car,
speed limits would mean nothing – they measure how much higher you’re going than 0 mph,
right? The Prime Meridian (that’s 0° longitude
on the globe) won’t be a thing, which means modern navigation goes with it. Without it, planes and ships will be rendered
useless. GPS – gone. How can it measure the distance between two
places without a starting point? It wouldn’t even get that far without satellites! Yep, they wouldn’t work either since they
use binary code. If people can’t travel, then towns will
become isolated. We’d probably even go back to horses and
buggies and paper maps! Hmm, looks like we could use another “cup
half-full” example (although, can’t really measure the contents of that cup without zero!). At least your alarm clock will never ring
again! And you won’t need to go to work – schedules
and money now mean nothing! Oh, wait, but then grocery stores won’t
be able to stay open. Price tags, inventory, and, of course, the
freezers and refrigerators that store perishables! You’ll probably need to beef up your farming
skills and become completely self-sufficient because in a world without zero, entire economic
systems will cease to be! Modern mathematics, geometry, physics, and
other exact sciences would disappear. In fact, we wouldn’t be able to measure
time itself! There would be no dates or years – you wouldn’t
even be able to celebrate your birthday or know how old you are! And that brings me to my final point… – The Philosophical In numerology, zero is the beginning, the
source of all numbers – it practically symbolizes the root cause of everything. “Yeah, but what about negative numbers?” Hey, I hear you – and they go back from
zero! Without this oh-so critical starting point,
you can’t move in time or numerology either way! Every atom, substance, and molecule in the
universe came from something, and that something is zero. Time is measured from it, right? The universe started with a bang, and space-time
has been expanding from there. Without time, there is nothing. No planets spinning on their axes and revolving
around stars. No constellations or galaxies. It all goes… Well, zero is a little more than “nothing”
now, isn’t it? Of course, don’t expect any “zero apocalypses”
to ever happen – this is all purely hypothetical! But even though the absence of this number
is downright terrifying, zero is still incredibly fascinating. To understand what I’m talking about, you
need to immerse yourself in mathematics! Like in a hot tub of math! – The Impossible Equation You can add zero, subtract it, and multiply
by it, but you CANNOT divide by zero. You might remember your math teacher stressing
that point, but did you ever wonder why that is? I mean, it works the other way around – you
can divide zero by another number. For example, you have 0 pieces of gum (your
pack’s empty – bummer!), and your 5 friends each ask you for a piece. That’s 0 ÷ 5, which equals 0! Everybody gets no piece of gum because there
was none from the start. But if you switch that around and punch 5
÷ 0 into a calculator, what do you get? Error! It’s a little confusing, I know. So let’s find out what’s so impossible and
senseless about dividing by zero with a fun little project! Grab a pen and piece of paper and draw a horizontal
number line. The beginning of the line is zero, and then
it goes 1, 2, 3, and so on. Now you need to refresh some knowledge from
your school days – namely, what inverse numbers are. These are two numbers whose product is equal
to unity. I’ll explain with an example. Look at number 2. Its inverse will be one half: 1/2. The same goes for any other number: the inverse
of 5 is 1/5, 6 is 1/6, and so on. In short, we divide the unit by the main number
(1, 2, 3…) and get its inverse. It doesn’t matter what the original number
is – 2 vs. 1/2, 10 vs. 1/10, 500 vs. 1/500! – the inverse will always be closer to zero. It’ll never fall below 0, and it won’t
go above 1. As for zero, this inverse number equation
will never work with it! Now for my favorite part: The further any number is from zero (3, 32,
192, 500), the closer to zero its inverse gets (1/3, 1/32, 1/192, 1/500). And the closer the inverse number is to zero,
the further down this number is from the starting point (0) in our number line. Now imagine this starting point. Can you create the number whose inverse is
equal to zero? Zero is less than any positive number, so
its inverse should be greater than any positive number. Which number is greater than ANY number? The answer is infinity! This is why you can’t divide by zero. The result is infinity, which is something
our brains just can’t grasp. Zero and infinity, two seemingly opposite
concepts, come hand-in-hand and are equally incomprehensible. We might not entirely understand zero, but
one thing’s for sure: we can’t live without it! Well, that sure wasn’t plenty of nothing
now, was it? Aren’t you happy we zeroed in on that. Aren’t you sick of these jokes? Hey, if you learned something new today, then

  1. Due you know I live India and I am proud to be Indian as 0 was invented in India and world's billionaire and millionaire are made by India because if we add 0 after any number it value increases
    So that means if 0 was not there then today no billionaire and millionaire would be there.

  2. Actually zero comes from aryabhatta in pataliputra(present day Patna, India) in 405 CE during Gupta empire reign of Chandragupta II

  3. Anything divided by zero equal zero, because if you have 5 pieces of gum but no friend then each nonexistent friend get no gum because they don’t exist! Also how is anything divided by anything infinity? That’s like giving your nonexistent friends infinite candy.

  4. Speed Limits Would Just Have To Move 1 up or 1 down,,, 69 < 70 > 71,,, 🙌 numbers would have to jump from 9-11, 19-21, 29,-31, etc??? !

  5. Would this mean there wouldn't be any grades in Denmark or any other country where grades are numbers? It's numbers so I think they would/should dissapear too!

  6. Yeah but if we didint come up with zero we could just us a nother number like instead of 01100110001101 we could do 1222111222111222211 or we could type out the word zero like 2zero witch stands for 20 but I house you couldint buy or do everything but like the 1221122111221222 stuff we could have lights and phones and we would just live in the old days for well ever intill God says OKAY OKAY heres a numder jeez here its called zero0
