On 14 March 2013, CERN announced the discovery of a particle with the qualities theorized by Peter Higgs (above) in the 1960s. The discovery of the Higgs boson was arguably one of the most significant experimental results in the history of particle physics, confirming why certain particles have mass and others do not.
Sy Montgomery, author of the book “The Soul of an Octopus: A Surprising Exploration into the Wonder of Consciousness,” reflects on the uncanny intelligence, intuition, and surprising sex lives of octopuses.
Remembering Newton’s Third Law for the next time I am in space and am being pulled towards the fuel-burning backside of a spaceship.
Today we have a simple post which will break down Newton’s laws of motion so even the layman can understand them inside out (hopefully). Mathematical formula will be introduced, though no previous knowledge of mathematics is required to follow this through – i’m going to explain every single piece of notation as best I can. For those that have a degree of mathematically proficiency already I do apologise that this may seem far too easy! For those that don’t, grab a pen and paper and stick with this!
Newton’s laws of motions are three laws that together form the basis of classical mechanics. Newton’s insight was so advanced for his day (17th century) and it was he who taught us for the first time how to understand the spatial behaviour of objects and the relationship between forces and motion. Physics may have advanced leaps and bounds since Newton’s day but…

Amazing, right? I took this photo recently, while I was visiting Xi’an China. No visit to Xi’an is complete without, of course, visiting the Terracotta warriors!
Fun fact: No two faces are exactly the same, leaving archaeologists to believe that the warriors were modeled after real people.
Question: What year was the Terracotta Army found? In 1974 by a farmer named Yang Zhifa who was digging a well, and instead ended up stumbling across a Terracotta Warrior.
According to my tour guide Jiajia (or Lady Jiajia, according to herself) Yang is usually nearby signing copies of his book. Sadly, he wasn’t there when I visited.
Another fun fact: Emperor Qin would drink mercury in small dosages because he thought that it was good for his health. However, it was what eventually ended up killing him. Although the Guardians to Emperor Qin’s tomb were found 42 years ago, the actual tomb has yet to be excavated. (The photo below shows the mound Emperor Qin is buried in). One of the reasons this mound has yet to be excavated is because Emperor Qin’s tomb is covered in mercury and traps as per Emperor Qin’s wishes before death. Scientists tested the mound and were able to figure out that it does, in fact, contain very high levels of mercury.
Interesting, right? If you ever have the opportunity, I sincerely recommend visiting the Terracotta Warriors. It is out of this world! Pictures are one thing, but seeing this in person will blow your mind!
(Please tell me if there is anything else you think I should know about the Terracotta Army! Shout out to Jiajia for being an amazing, enthusiastic, and informative tour guide!)
