CT scans are a vital medical imaging technique for diagnosing, treating, and preventing diseases by providing detailed cross-sectional images of the body. By converting X-ray attenuation data into a sinogram, CT scans visualize internal structures with high precision. Advances like helical scanning

To many, prime numbers are a useless concept studied in maths and soon forgotten about, having no impact on the rest of our lives. While they do have some applications in computing and encryption, primes never seem to crop up in day-to-day life, remaining as “special numbers” that aren’t all that sp
Physics
All particles in nature are in constant motion, which makes it particularly challenging to observe phenomena on the atomic level. This problem was solved by the recent development of laser cooling techniques.

When attempting to estimate the population variance using samples, n-1 is used instead of n. Why is this the case? This article looks into the proof of Bessel's Correction and demonstrates its effects using data.

Space: the final frontier. If conquered, it offers unimaginable wealth, sci-fi tech, and the key to humanities survival in the next millennia; read more to understand the challenges and possible solutions to beating humanities final foe.
Problem of the Week
There are 25 red balls and 25 blue balls in a bag. Alice and Bob take turns drawing balls from the bag without replacement, with Alice going first. Interestingly, they notice that whenever a red ball was drawn, the next ball drawn (by any person) was never red. Suppose Bob drew m red balls. Given th

Hundreds of years ago, scientists believed that air was a pure substance which, alongside earth, wind and fire, made up all matter on Earth. Nowadays, we know that air is a mixture of gases. 1 mole of air contains: 0.78 moles of nitrogen 0.21 moles of oxygen 0.01 moles of argon

The world’s first commercial jet aircraft, the de Havilland Comet, took its first flight in 1949, marking the beginning of the jet age for air travel. Today, over 4.5 billion passengers annually enjoy fast, convenient and relatively affordable travel in the 25000 aircraft flying in the global commer
