A tribute to Röntgen

Today 115 years go a German physics professor Wilhelm Röntgen stumbled on X-rays while experimenting with Lenard and Crookes tubes.

Thanks to this guy now we can see what caused my dog bandit the excruciating pain he felt after jumping from my bed to the floor (about 2' high).

Mind you he is a Jack Russell Chihuahua mix. Not that big although he thinks he's bigger than anyone around, and Jack Russell supposedly a smart breed, but I think the Chihuahua in him kinda lower his overall intelligence.

Here is a pic of him and how high the bed is compared to his stature.
