The standard model describes four fundamental forces; gravitational, electromagnetic, strong and weak. How is gravity different? [Read more…] about How does gravity compare to the other fundamental forces?
There are four fundamental forces of nature: gravitational, electromagnetic, strong and weak. Each force can be explained using fields and 3 also have bosons associated with them, known as force carriers. [Read more…] about Fundamental Forces
In a group of 23 people, the probability that 2 of them share a birthday is 50%. This fact may seem strange at first, but can be proven by fairly simple mathematics. [Read more…] about The Birthday Paradox
Galaxies within the universe have been observed to be rotating much faster than we had initially predicted. The gravity produced by the matter which we can observe is not enough for these speeds to be reached, therefore scientists believe that there is extra mass in the universe that we just cannot see, dark matter. [Read more…] about Dark Matter
The rate of expansion of the universe is increasing however, scientists have no explanation of why. The force of gravity should be slowing it down, but we have concluded that there must be some other energy in the universe causing this expansion to accelerate. [Read more…] about Dark Energy
Covering some of the most intriguing mathematical problems, this book gives a detailed insight into the history and applications of mathematics. The problems introduced became famous either because they took many years to solve or they remain to this day to be proved.
A wide range of topics are covers, such as the Goldbach conjecture. This suggests that all numbers greater than 2 can be written as the sum of two primes. In the book, Stewart explains in simple terms first what is meant by a prime number before going on to explain the conjecture in more detail.
Containing 6 chapters in all, the book introduces progressively higher mathematics as it goes on. This means that for anyone without background mathematical knowledge may struggle with later chapters, although Stewart does explain new concepts in a lot of detail.
This book not only gives the reader a broader understanding of mathematics as a whole but also highlights the importance of mathematics as a whole. Stewart also introduces new concepts which the reader can then go on to research further if they want to.
