Einstein

Albert Einstein was a pioneering physicist who arguably gave classical mechanics the face lift it desperately needed at the turn of the 20 th century. He provided us with the elegant theories of relativity describing gravitational fields of large objects, as well as the wave-particle duality nature of small objects such as photons which exhibit the wave like properties of light: Einstein's work involved his relativity theories on gravitational fields of large objects such as stars, as well as the wave-particle like properties of light . Einstein spent his remaining time searching for a theory which reconciles relativity with quantum mechanics, thus providing a complete description of the universe, which to this day remains an unsolved problem in frontier physical cosmology. I covered this problem in my previous entry entitled ‘ Gravity ’, indeed we have some exciting and imaginative ideas which provide theoretical solutions, but lack experimental evidence.   Also, in his l...

Our current understanding of the physical nature of the universe can be accurately described by two mathematical constructs, quantum mechanics and general relativity. Quantum mechanics describes the behaviour of small objects such as particles (small fundamental building blocks) using statistics. General relativity describes the behaviour of large objects such as planetary bodies using empirical observation. Whilst both constructs are extremely accurate and have large amounts of experimental evidence, problems occur when one tries to unite these theories given their different mathematical constructs. If these theories could be united the properties of blackholes and the beginning of the universe can be described, both of which posses large and small characteristics such as a singularity (an infinitely small point) and a vast size making them telescopically observable. The problem lies with gravity. Quantum mechanics predicts the existence of a graviton (a particle of gravity)...
