My favourite piece of apparatus is a GPS station. This is like the one in your phone or a car sat-nav, but much more accurate. We can measure things down to the millimetre level. This is really useful to monitor how volcanoes move or deform before eruptions.
Very nice and different question Laytolli! I like one of my robot, because it is so sophisticated, helpful and complex, perform so many functions for me. It has arms, legs, brain (computer) and it is super-fast. It can make hundred of crystallization plates without any error, very accurate and in few minutes. I love it <3
I think from school I remember liking electrical circuits and joining everything up to make the light bulb come on.
These days I think my favourite apparatus, or equipment would be a radiation monitor. These are often called Geiger counters in films and things. They are invaluable as we can’t see, smell or hear radiation so you have no idea where it is, unless you use some kind of monitor. We use them all the time at work, to check for spilled radiation like from injections, to find how far a patch of contamination has reached, to check the patient toilets are OK for the cleaners to go in at the end of the day, and even to estimate how much radiation is left in a patient and whether they can go home. We would be lost without them.
