What are rudimentary measuring insrements?
Measuring cups. Our first measuring instruments would have been our hands, then large leaves, empty plant and animal shells - gourds, seed husks, turtle shells, skulls, and so on.
Did the Romans invent the dentist drill?
No they didn't because that would not be possible because they didn't have electricity. That is certainly true, however it should be mentioned that the act of drilling teeth goes back thousands of years before the Romans, to the Neolithic era. Graves near a Neolithic town in Pakistan show the skulls of people with clear evidence that their teeth had been drilled, complete with drill marks. The teeth were in the back of the mouth so could not have been drilled for decorative purposes.
Based on the graph shown below what size antlers would you expect on an els with a skull 470 mm long to have?
Without seeing the graph, I can't provide a specific answer regarding the size of antlers for an elk with a 470 mm long skull. Generally, antler size is correlated with skull length; typically, longer skulls may indicate larger antlers. If the graph shows a trend or relationship between skull length and antler size, you could estimate the expected size based on that trend.
Is phosphorus on some hands of the clock?
Yes. These were originally known as Radium dials until the dangers of Radium were realised (people used to paint their teeth with Radium, to make them glow in the dark, with the result their jaws degenerated and literally fell off their skulls). You can still get radiation poising from old Radium dials, as the half-life of Radium is 1600 years. Phosphor dials (and sometimes Tritium) replaced Radium dials and is a much safer method of making the hands of analogue clocks, watches and other dialled instruments glow in the dark. How long they glow is dependent upon the amount of light absorbed by the phosphor.
