So, I am visiting my parents in NJ, 36 degrees outside. They heat the house to 68 degrees, primarily with the thought that it is less expensive than heating the house to 72 degrees. HOWEVER my thought is that once you reach your desired indoor temperature, it is no difference to maintain the house at 72 degrees than it is at 68 degrees, at least when the outside temperature is that far away from your desired inside temperature. Is this logic true, is it going to take more energy to maintain the inside temperature at a higher degree, or is it just the initial closing of the gap where the cost is?

1. Solve 2x^2 - 3x - 1 = 0

2. express 5 - 2 ln x^3 - 2 ln y as a single logarithm.

3. simplify 2x^2 multiplied by the 5th root of x then all of that divided by x^0.

4. write down all the factors o 15 and hence factorise x^2 - 8x + 15.

I know a real vacuum can't exist (third law of thermodynamics and common sense), but what's the closest we can get?

And why the hell can't I wrap my head around something as simple as nothing? It just seems absurd to me, as to the vacuum scientists of old.

While I'm at it, are all known elementary particles point particles?

More importantly, how the hell do we know they're point particles? How do you expect to tell a point particle from a really really small particle? How can point particles even contain information to interact with the world with?
