So we started with a set of nearly 50 different specifications that we generated from experimental observations of embryonic stem cells.

我们从一套大约有 50 个不同的技术规范开始，这些是我们从对 ES 细胞的实验观察值中得出的。

Classical physics, grounded in continuous energy flows, couldn't explain why the energy radiated by a black body at different frequencies didn't match experimental observations.

以连续能量流为基础的经典物理学无法解释为什么黑体在不同频率下辐射的能量与实验观察不符。
