# Top 9 things that totally change when you modify 0.1%

0.1% is really not much. But in some cases, it’s just huge. If we change 0.1% in certain objects, certain statistics or certain situations, it changes everything. Look at these examples, and you will understand that 0.1%, or even less, is already a lot.

## 1. A rocket launch can fail if its code is changed by 0.1%

The Mariner 1 rocket crashed due to a hyphen in its code. It’s a version that is often questioned and could be an urban legend, but it reflects something that could be true anyway. The unwanted hyphen in the rocket code was less than 0.0005% of the code. And yet, it’s enough to make the whole machine malfunction. When we know what level of precision must be used to launch a rocket, we can understand that 0.1% is way too much.

## 2. Steel can become brittle if you change 0.1% of its composition

There are steels, like 1095 steel, which contain 0.95% carbon. If we change this carbon composition by 0.1% more or less, the steel loses some of its properties, such as its strength, for example.

## 3. If we change an angle by 0.1%, over a long distance, the difference is enormous

Move forward two meters at the wrong angle: the error in relation to the initial trajectory will not even be visible. On the other hand, sail for 2 months on the water with the same error of 0.1%, and the difference will be felt. Now do the same thing over 10 light years in space, and that 0.1% angle error will be nothing short of catastrophic. In short, changing an angle, the more distance there is, the riskier it is.

## 4. Plane crashes

In 2017, there were around 37 million airline flights for just 10 accidents. That’s about 0.00003%. Imagine if “just” 0.1% of flights had an accident. That would be about 37,000 plane crashes a year. It would just be awful. No one would want to fly anymore.

## 5. Our DNA

We know that we have 99% of DNA in common with the chimpanzee, and 98% with the pig. It already gives a good idea of ​​the importance of the 1 or 2% DNA difference between our species. It’s plausible to say that another human with 0.1% DNA different from us can look just as good as us or totally screwed up, with a pig’s nose or 3 pairs of legs. In short, let’s not try to modify our DNA by 0.1%.

If you want to know stuff about genetics, it happens here.

## 6. If the heart of 0.1% of the world’s population stops now, there will be 7.5 million deaths

Normally, there are around 157,000 deaths per day. 7.5 million would be huge. This is the equivalent of the number of inhabitants in Bulgaria or Togo. Can you imagine Bulgaria being emptied of all its inhabitants in the blink of an eye? Ok, you are imagining a yogurt. Nice mentality guys. It’s not just yoghurt in Bulgaria.

## 7. The blood alcohol level in the car

0.5 grams of alcohol per liter of blood is the dose that should not be exceeded when driving. If we are at 0.5 during a control, we pass. If we are at 0.6, we toast. Finally, we don’t toast champagne with the police, but it goes to fines and withdrawal of license, and it’s not funny. So for 0.1%, the difference is quite large.

## 8. The number of data on the planet

In December 2018, it was estimated that there were around 33 zettabytes of data in the world. By losing just 0.1% of all this data, we would lose 33,000,000,000,000,000 bytes of data. Or 33 million gigabytes, if you prefer. It would be a very big loss (but if there could be Nadine Morano’s tweets in it, we wouldn’t mind).

## 9. A hesitation of 0.1% of a second when your mother asks you if you like her blanquette can kill you

There is only one correct answer to this question: “Yes, is there any left? » Now you will know.
