When I was a young researcher, doctoral student, my first year, I had a research professor who said to us, "Here's the thing, if you cannot measure it, it does not exist."
Kui ma olin noor teadlane, doktorant, oli mul esimesel aastal uurija-professor, kes ütles meile: "Lugu on nii - kui seda ei saa mõõta, siis seda pole olemas."
