For example I have measured the height of our house with trigonometry, checked the building info and I was correct. Now, I want to do experiments with logs, derivatives, integration, etc. at home or in our garden. How? Any good ideas for easy experiments? Nice to be here, trickybilly

I suggest you use a rake, weed remover and a spade.

Lol. It works for physics though:
-carboard+thread+weight makes a sextant. If you point it at the polar star you get a coordinate.
- magnet+1,5V battery+wire makes a homopolar motor
-syringe+magnet+wire loop+LED makes a generator, etc.
Experiments like these got me from Ohms law in February to constructing motion detectors, mobile phone detectors, primitive memory units, laser alarms, Arduino microcontrolloer projects and currently building an 8 bit Ben Eater computer from Youtube. Maybe I could make some motion detector and somehow make a basis for math from those experiments, but there must be an easier solution.
I am a G.P. specializing in internal medicine, so this is only a hobby in my spare time, so feel free to correct me whenever I am wrong. Hope there math will provide great spare time as physics does.

Yes, that sounds just about right. Welcome Dr. trickybilly, I say welcome. 'Tis not often that we get an M.D. (or is it "a M.D.") hereabouts. That thou art into the black arts of mathemagics besides being into the empirical nature of thy profession must mean, to my hammered mind at least, that thou art a very curious person indeed. Incidentally, would you perhaps also consider doing some online "differential" diagnosis from time to time for some aging math knight-errants hereabouts?
