On mortgages

-Should use have a fixed interest rate if interest rates are going up

-Should use a variable interest rate if interest rates are going down

-for variable, it’s a gamble, but if it goes up, you might’ve offsetted it with he previous year if the previous year was lower

-typically a variable rate has lower interest rates than fixed

-Pre-approval should be done to find your buying power

Uncertainty Principle

If you fire an electron gun into a piece of paper with two slits, the wall behind the paper will have marks right behind either of the slits (this is with a detector counting the number of electrons passing). If you remove the detector, then the pattern on the wall looks more like if a ripple of water passed through the slips. 

Basically, this is saying the electrons behaved like a particle with the detector, or like a wave without the detector.

Dollar Value

-If a country increases their interest rates (say the US increases its interest rates ins savings bond), the value of the the currency is likely to go higher since more people will want to invest into the US dollar). This may result in higher mortgage interest rates though (which is bad for me :/)
