It’s bad enough for the first kid when a new baby shows up to steal your thunder. But the injustice is compounded when you have to start wearing glasses while your little sibling stays as cute and non-four-eyed as ever. If this sounds familiar, you’re not alone: firstborn kids are more likely to be nearsighted…

As we reconcile ourselves to the reality that four eyes are better than none, we might spare a thought for John Tyndall; he died on this date in 1893.  A prominent 19th-century physicist, he was known for his work on a range of subjects, from crystals to diamagnetism and infrared radiation.  But he is probably best remembered as the man who explained (in his book Light) why the sky is blue.  And he was perhaps most impactful in his development of the “light fountain“– which demonstrated the scientific foundation for modern fiber optic technology.
