Surgery is a growing field. New technologies and methods for carrying out procedures are constantly evolving, making surgery much more safer and result in higher success rates. However, in the past, this wasn't at all the case. All aspects of medicine weren't as advanced and were completely different, including surgery. Anaesthesia wasn’t even around until … Continue reading The History of Surgery
Offender profiling, also known as criminal profiling and psychological profiling, is an investigative technique used by law enforcement to help catch the perpetrator(s) of crimes, especially serious ones. It is based on what type of person the perpetrator is like through analysing the crime and crime scene. Image by Emilian Robert Vicol from Pixabay There … Continue reading What is Offender Profiling?
Atoms, derived from the Greek word ‘Atomos’, meaning indivisible, make up everything in the world. They are the smallest part of elements that can exist, but what exactly is the structure of an atom like on the inside? Protons, neutrons and electrons, which are subatomic particles, make up atoms. Each proton has a relative charge … Continue reading The History of The Atomic Model
As Women’s History Month comes to a close, it’s only fitting that we remember the work of the women who have contributed to the field of STEM throughout the years. Here are 5 women who have been invaluable in the fields of science, technology, engineering and mathematics and paved their way through a male-dominated system to become some of the greatest names in STEM history. Yvonne … Continue reading The Women of STEM: 5 Women Who Shaped The World of Science and Research
The speed of light is as frustrating as it is fascinating. The speed of light in a vacuum is the fastest thing we can measure at 300,000km per second, although in a vast and ever expanding universe, it is painfully slow. The universe currently measures 45 billion light years in all directions of observation. So … Continue reading The Speed of Light – So Agonisingly Slow.
Time travel has been a key component of science fiction for literally hundreds of years. In our reality, or should I say interpretation of it, is time travel actually possible? Kip Thorne, the most recent Nobel Laureate for physics certainly seems to think so. Thorne theorises that interstellar travel is possible via a wormhole. Thorne … Continue reading Time Travel Using Wormholes.
Alongside black holes and white holes, wormholes have held a position of wonder in real physics as well as science fiction. A wormhole is a theoretical cosmic object that connects two different points in space and time. As per Einstein, wormholes could theoretically connect two different universes. American physicist John Archibald Wheeler coined the term … Continue reading Wormholes Series : Intro
On the 11th of February 2016, the Laser Interferometer Gravitational Wave Observatory (LIGO) announced that they had detected the first evidence of the existence of gravitational waves the previous September. At the time this was a massive triumph for the team that observed them and made headlines worldwide. So what are gravitational waves? In 1916, … Continue reading Gravitational Waves
Sagittarius lies at the centre of the galaxy and is represented in mythology as a Centaur pulling back a bow. From the northern hemisphere, the brighter stars are easily recognised from an asterism known as the teapot. The brightest star in Sagittarius is Epsilon, a rapidly spinning binary star. At 143 light years from us, … Continue reading The Constellation Sagittarius
I admit, last weeks post was slightly shorter than most other posts I’ve ever written. Following on from this I have decided to complete a series on the signs of the zodiac from the point of view of astronomy. The Zodiac are the star groups and systems can observe from Earth depending on the time … Continue reading Signs Of The Zodiac Series
