论文摘要
1919年，爱丁顿和戴森（Eddington）和戴森（Dyson）领导了两次著名的探险队，以衡量日食总弯曲。这项工作的结果导致了爱因斯坦一般相对论的首次实验确认，并有助于创造其独特而持久的名望。从那时起，全世界都进行了类似的实验，证实了一般相对性的预测。后来，无线电干涉法的发展提供了一种更准确的方法来测量重力挠度。我们认为，经过一个多世纪之后，由太阳的重力引起的星光偏转仍然代表了一种简单而直观的方式，可以将高中生引入一般相对论及其影响。为此，我们收集了从1919年到2017年的八个日食中进行的测量，并创建了一个同质价值的单个数据集。本文与整个数据集一起为学生提供了一个可能的小组活动的蓝图，有助于以一种有趣的方法在物理课中介绍该理论。
In 1919, Eddington and Dyson led two famous expeditions to measure the bending of light during a total solar eclipse. The results of this effort led to the first experimental confirmation of Einstein's General Relativity and contributed to create its unique and enduring fame. Since then, similar experiments have been carried out all around the world, confirming the predictions of the General Relativity. Later, developments in radio interferometry provided a more accurate way to measure the gravitation deflection. We believe that - after more than a century - starlight deflection caused by the Sun's gravity still represents a simple and intuitive way to introduce high-school students to General Relativity and its effects. To this aim, we gathered measurements taken during eight eclipses spanning from 1919 to 2017, and we created a single dataset of homogeneous values. Together with the whole dataset, this article provides a blueprint for a possible group activity for students, useful to introduce the theory in physics classes with a playful approach.
