The Fibonacci Sequence, Golden Ratio and Golden Spiral An introduction to the world of sequences and ratios Introduction to the Fibonacci Sequence The Fibonacci Sequence is a set of integers in which each number, except for the first two, is equal to the sum of the two preceding ones. Numbers

I have always enjoyed researching and learning about mathematical paradoxes. Partly because they are interesting to think about, and partly because they make us question our already-existing knowledge about the world around us. The Infinite Hotel Paradox or Hilbert's Paradox of the Grand Hotel is one such paradox,

Research regarding cancer treatment has gradually improved over the years, expanding the range of effective intervention methods: From tumour removal surgery and radiation therapy to targeting rapidly growing cells with chemotherapy. Now, thanks to ever-expanding research, scientists have come up with another treatment that has proven more effective than the

An Overview Obsessive-compulsive disorder (OCD) is a long-lasting mental and behavioural disorder featuring patterns of intrusive thoughts and fears known as obsessions. Obsessions are persistent unwanted thoughts, mental images, or urges that cause feelings of anxiety, disgust or discomfort. Such obsessions may lead one to do repetitive behaviours, known as

Introduction The ratio between a circle's circumference and diameter is a mathematical constant known as pi. (i.e. C∕D=π) It is estimated to be around π ≈ 3927⁄1250 = 3.1416 (accuracy 2·10^-6). Two of the very earliest civilizations, the Ancient Egyptians and Babylonians both
Science
Introduction The famous Double-slit experiment is known for providing evidence for the fundamentally probabilistic nature of quantum mechanics. Interestingly, it reveals how electrons and photons switch between particle and wave behaviour following mere observation. The abstract and overarching term “observation” is hard to account for in attempts to explain this

Hormones are chemical messengers that coordinate different functions in the body. The endocrine system, which is made up of all the body's different hormones, regulates all biological processes in the body, from growth and metabolism to conception and brain development. Hormones, produced by glands, regulate long-term ongoing processes
Science
Introduction to the Nervous System The first principle of the biological approach to behaviour is that behaviour is the product of physiology. The term physiology is an umbrella term that encapsulates the structure and function of the nervous and endocrine systems. However, to fully understand this principle, one has to

The brain is recognized not only as the most complex organ but also the most important one in the human body. One of the major reasons why the brain is regarded as our most vital organ is due to its unique ability to influence and interpret emotions and communicate with

Introduction to Neuroplasticity Neuroplasticity is the brain's ability to change by modifying synaptic connections between neurons typically caused by genetic and environmental factors. Genetic factors refers to the normal pre-programmed development of the brain, while environmental factors include injury, brain damage or acquiring new skills. Naturally, there are

Localization of function is an idea that explores the connection between patterns of behaviour and parts of the brain. This idea has a long history, dating back to ancient times when scholars like Hippocrates speculated about the brain's role in behaviour. However, it was not until the 19th

The Little Albert experiment was a famous psychology experiment conducted by John B. Watson and graduate student Rosalie Rayner, in the mid-20th century. Inspired by Russian physiologist Ivan Pavlov, who conducted experiments demonstrating the conditioning process in dogs, Watson wanted to take the research a step further by demonstrating that
