Det er ikke mange som korrigerer meg når jeg snakker, og jeg vet faktisk ikke om det er riktig å si "sant?" etter at man kommer med en uttalelse. Jeg sier «sant?» nesten hele tiden, altfor ofte bare av vane, men jeg vet ikke om det blir feil i noen situasjoner. Her er noen tilfeldige eksempler:

Det er koselig å bruke stormfulle dager til å sitte på sofaen og lese en bok, sant?

Når man går på jobb, må man prøve så godt man kan å legge igjen den negative stemningen hjemme, sant?

Vi skal på kino på Fredag, sant?

Er det bedre å si "ikke sant" i noen situasjoner? Er det for direkte å bare si "sant?"

I have never made videos like this before, but I'd like to try to make short science videos and I'm not sure what the best platform is. I am currently trying out Canva, but I'm not sure how to draw in the video and make what I draw move, and so on. Is there a better program that saves a lot of time making the graphics?

I completed a bachelor's degree in geophysics and a master's degree in meteorology. Although I feel confident in my understanding of the deeper scientific principles, I have realized that I am less confident when it comes to some of the basic concepts and general meteorological knowledge. I know it's partly a feeling and not all true, but I am reading up and doing a lot of studying these days on the basics, but I am scared that this is mostly just imposter syndrome, and I am always going to feel like that.

I just wanted to see if someone else is in the same boat?

I've been trying to get a better understanding of non-inductive charging, specifically what controls the sign of the charge acquired by graupel during collisions with ice crystals. My understanding is that graupel is often negatively charged under typical thunderstorm conditions, but that the polarity can reverse under certain temperature and liquid water content regimes.

Is the physical mechanism behind this polarity reversal well understood, or is it still an active area of research? I've come across several explanations, but I'm having trouble determining how settled the science actually is.

Furthermore, what causes the bottom of the cloud to be positive when the middle is negative? And does it always happen?
