The End of Moore’s Law

In 1965, Gordon E. Moore, the co-founder of Intel, observed that every two years the amount of transistors that could fit on a single microchip was doubling, whilst the cost of computers was halving. Moore’s Law, a projection of this historic trend, has been used since 1975 for forecasting and goal-setting in the semiconductor industry.Continue reading “The End of Moore’s Law”

Approximating the Universe: Perturbation Theory

The theory of quantum mechanics is humanity’s most honourable attempt at describing the nature of the most fundamental building blocks of the Universe. Providing a quantitative understanding of subatomic particles and their interactions, the theory has stood up to one hundred years of experiments testing its validity with only minor deviation from observations. The agreementContinue reading “Approximating the Universe: Perturbation Theory”

Lasers: Well-Behaved Light

The theoretical foundations of the laser were put forward by Einstein in 1917 but it wasn’t until the 1940s that physicists found applications for his ideas. Nowadays, lasers are responsible for a multi-billion pound industry which includes correcting vision defects through laser eye surgery and sending data across the globe via optical communication. The operationContinue reading “Lasers: Well-Behaved Light”
