Recently, the topic of the global warming appeared in the news again, mostly in connection to the newly appointed U.S president and his cabinet; seemingly not having much of support in the current Washington administration. The question we need to ask is: What is the evidence for the global warning, and can we possibly reject … Continue reading Changing climate – the evidence behind our biggest environmental challenge
In my last post I discussed the principles of special relativity. To recap, the speed of light is invariant for all observers in all reference frames. Special relativity tends to deal specifically for non-accelerating frames of reference, what we call an "inertial frame". General relativity is much more in depth regarding reference frames and can … Continue reading Does The Apple Fall to The Ground? Or Does the Ground and Everything on It Accelerate Upward into The Apple.
Astronomers involved in The Pale Dot Project found a potentially habitable planet orbiting Proxima Centauri. Named Proxima Centauri b, the planet orbits its parent star Proxima Centauri in around 11 days, with surface temperature favourable for the presence of liquid water on its surface. This rocky world has a slightly bigger mass than Earth, and … Continue reading Discovery of an Exoplanet within habitable zone around the star closest to Earth.
Norovirus is also known as the winter vomiting bug as it is more common in the winter months but it can occur at any time of the year. Before being called Norovirus is was called Norwalk Agent after the place it was first identified, Norwalk, Ohio. In 1968 an acute gastroenteritis outbreak occurred in the … Continue reading Norovirus – A Tummy-turner of a Virus
There have been many female scientists throughout history but for one reason or another many of them are not well known despite their incredible contributions to their area of study. Due to the male dominated society of many countries in past centaury’s these women fought hard to not only receive more than a primary education … Continue reading The Mother of Computer Science (Ada Lovelace)
It is fair to say that absolutely everybody knows who Albert Einstein is. What many people don't know is why he is regarded as a genius. Einstein's theories of Special and General Relativity have transformed our notion of reality and these theories are central to modern physics. They govern the laws of nature and our … Continue reading Introduction to Special Relativity
Welcome to my blog post – this month it is all about sharks! I was recently watching a BBC documentary (imaginatively titled ‘Shark’!) which first aired in 2015 and I was fascinated by one of the scenes in the documentary. It wasn’t a scene of a great white nor any impressive acrobatics of sharks jumping … Continue reading Sharks!
So far, we have focused on the grandeur and scale of the heavenly bodies and how they were formed in the Primordial Era of our Universe following the Big Bang. Visible matter i.e. stars, galaxies, planets, nebulae, interstellar dust, comets and asteroids only accounts for 5% of what the universe is actually made of. In … Continue reading Electrons, Quarks, The Higgs Field and The Building Blocks of the Universe
General relativity could be regarded as being one of the greatest achievements of science in human history. As early as the 1600’s Isaac Newton was considering the causes and effects of gravity. He formulated his famous equation of the gravitational force; Figure 1 - Newtonian Gravity – Wikipedia It states that the force between two … Continue reading Relativity and Gravity
We have come along way you and I. From the first instant of space and time right up to now. In 4 blog posts we have travelled 13.8 billion years through time to get where we are now. Through life we learn that nothing lasts forever, this unfortunately includes our universe. There are supernova remnants … Continue reading Mind Blowing. The Great Acceleration. Dark Energy.
