Want facts and want them fast? Our Maths in a minute series explores key mathematical concepts in just a few words.
Generating electricity without the use of fossil fuels is not just an engineering and industrial challenge, it is also a huge mathematical challenge.
In this podcast author Coralie Colmez shares insights into her novel The irrational diary of Clara Valentine.
We talk to early career mathematicians who spent some of their summer holiday solving problems posed by industry — such as how to blend a perfect smoothie!
Don't like plantbased meat alternatives, but want to spare animals and the environment? There's hope on the horizon, aided by a good helping of maths.
Inverse problems are mathematical detective problems. They can help solve crimes, are used in medical imaging, and much more.
Someone wrote: Any integer number divisible by integer k can be represented as the sum of k prime numbers.
This is simply stating in the trivial case for P prime : k.P=P+P+P+...+P, k sums of the same prime.
If P in above sum is not prime, it can be broken up into its prime factors and you get a sum of primes again.
So the above statement is basically the same as the breakup of a number into its prime factors and has not to do with the Goldbach conjecture.
