Medicine & TechnologyThe Olympians participating in the Tokyo Olympics are about to experience the hottest games in decades, reaching temperatures approximately 90 degrees Fahrenheit, not to mention suffocating humidity.
One property of quantum mechanics is superposition, which explains how a system could be in multiple states at the same time until the instant it is observed or measured. A theoretical study suggests that this phenomenon affects high-precision clocks.
In a microscopic context, fluctuations can cause phenomena that directly violate the second law of thermodynamics, leading observers to find the arrow of time being blurry and vague. However, a new machine-learning algorithm could help researchers in the future.
Scientists have set a new record in accurate timekeeping, by creating a new atomic clock that won't lose or gain a second in 15 billion years. This timespan is greater than the estimated age of the Universe itself.
