# Why mathematics in medicine? ### Why mathematics in medicine?

Whether to compare the effects of different drugs or placebos, to determine an ideal body mass index or to quantify the reliability of a screening test, the use of statistical and probabilistic reasoning is essential in medicine.

### What is the connection between mathematics and nature?

But the link between mathematics and nature is much deeper: mathematics is often essential to the understanding of phenomena and it makes it possible to make unexpected predictions that will only be observed much later. Here are two fascinating examples.

### What are mathematical objects?

Beyond their fascinating beauty, we can also see mathematical objects in them, since the spirals of the sunflower flower follow a famous numerical sequence called the Fibonacci sequence, the snowflakes present particular hexagonal symmetries and the morphology of the fern describes a fractal geometry.

### Why use math?

Conversely, mathematics is used to understand the phenomena that surround us: it is for example thanks to differential equations that we can precisely calculate the trajectories of the stars or predict the weather in a few days.

### What are the benefits of math?

Whether mathematics is just a representation that makes nature intelligible to study or whether it is its true language, this nature never ceases to fascinate, and it will certainly continue to do so for a long time.
