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
One of the enduring symbols of Christmas and The Nativity is the star the wise men followed to greet the baby Jesus. The star of Bethlehem as it became to be known, has been researched extensively and there are several hypotheses as to which celestial body the Magi (Wise Men) followed to reach a stable … Continue reading What Was The Star of Bethlehem?
We all see the apocalyptic social media posts of a doomsday event. Mainly an asteroid or supersized fictional planet impacting the Earth. Everyone hid under a rock in 2012 thinking the world as we know it was going out in a blaze of glory! It is accepted that a large asteroid collided with the Earth … Continue reading If An Asteroid Were Heading Straight For Us…..
