No. That's why I called them philosophers. |
So you are not up-to-date 
I would have if I had the time. |
This is lame excuse 
There may be instances, but general character of Hellenistic 'natural philosophy' (proto-science) lacks experimentation. |
This proofs that you don't know what are you talking about
.
In fact, the hellenistic one was not a "natural philosophy" but, on the contrary, in many instances it was against natural philosophy, in particular against the natural philosophy of Aristoteles (this is well explained in the book of Russo ...).
I am not sure what you consider 'experiments'. I am not really an expert on this era (or the Islamic one) but Hipparchus was an astronomer, wasn't he? What experiment did he do I wonder? Observation and modelling are not experimenting. |
You are right, Hipparchus was mainly an astronomer and one of the biggest ever lived. But he performed also some experiments in the field of gravitational Physics. Unfortunely all his works but one are lost and what we know about his scientific researches derives from secundary sources. In particular we know from the Greek philosopher Philoponus (who lived centuries after Hipparchus) that Hipparchus anticipated G. Galilei in his researches on falling bodies.
For more informations you have to read the book of Russo
