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
Coming to the end of 2016, I thought I would use my last post of the year, to reflect on some of the amazing physics and space/astronomy stories that have infused this year with so much excitement and intrigue. From the confirmation of the detection of gravitational waves (100 years after the famous general relativity … Continue reading 2016 – A Year of Science.
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
Around the middle of the 19th century, mathematics was undergoing a revolution. Certain Classical notions were being overturned and in their place, something altogether stranger was beginning to appear. Where previously it had been based around observations in reality, maths was now becoming its own language which it was hoped could describe and even anticipate … Continue reading Six Impossible Things Before Breakfast – The Physics of Alice in Wonderland
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
In this article I would like to discuss the conditions that enabled life to evolve on Earth, and the possibility of such conditions existing elsewhere within the Universe. First of all let us focus on the position of Planet Earth around the Sun. Earth is the third planet in a succession of the rocky planets within the inner Solar … Continue reading Is There Life on Mars?
