Except the terrible 2s terrible 4s part - they're nothing compared to the terrible teens. (or maybe pre-teens)
Yes there are children i.e. mellow children who don't need discipline and just explaining to them works. Then there are the rest who need to at least *see* discipline because they are spoiled little brats who only want to do what they want to do and to hell with everyone else.
All children need discipline, and the subjects of TFA don't disagree. You are confusing discipline and punishment, and it doesn't seem like the subjects of TFA are saying punishment must be avoided at all times. They doo seem to be saying that punishment coming from the person the child goes to for comfort is confusing to small children in a fundamental, brain-altering way.
That being said, TFA was pretty disjointed, often referring to things as if they were already explained when had not been mentioned before in the article, so how should I know what they were really trying to say.
What's actually needed is an engine to compress/expand the refrigerant. You can just as easily use a heat source to create the required pressure differential. RV refrigerators do exactly that, with no motors or moving parts. They cost an outrageous amount of money, despite being virtually identical in construction to electric ones
Not sure where you're coming from.
Combustion engine driven compressors are similar to electric motor driven ones, but are more complicated and certainly have plenty of moving parts.
Adsorption/absorption refrigeration systems have fewer moving parts, as they use heat as the main driving force and so don't have compressors. But they still have moving parts like pumps and fans, and they are completely dissimilar in design to mechanical compressor driven refrigeration.
Calculus is a good example, That's why everyone knows the name Newton more than three centuries after his death . . .
Then how come so few know the name Liebniz?
Now compare the amount of money that the government makes at the pump, compared to what the oil companies make. You know, the guys who find, extract, move, refine and ultimately sell it to us. In the US the ratio is 7:1*; in Europe it's much worse.
First, "the guys who find, extract, move, refine and ultimately sell it to us" are typically several different companies, only the biggest companies have that kind of vertical integration, and they rely on third parties for a lot of those tasks, anyway. Second, show us the numbers.
I think it has more to do with being light weight since birds fly.
Flying mammals like bats have the ability to fly without forgoing teeth for a beak.
Archaeopteryx, widely considered the "first bird." . . . flew, and sported plumes and chompers.
You shut down your laptop? What year is this? 2002?
It's another one of those years when MS Windows tells me it's going to automatically shut down my laptop in a minute, unless I'm looking at it at the time the dialog box pops up letting me delay the shutdown for 10 minutes or 4 hours.
7) Sometimes the physical buttons don't work and it will stop responding while my music is playing. Then suddenly it will catch up and all the times I hit forward or back on the track suddenly occur.
Sounds very similar to the gripes I have about the Microsoft GUI on my Uverse "cable" box / DVR.
I seldom need only one document open at a time, and landscape works much better for viewing multiple documents, especially when they have "standard" 8-1/2"x11" pages.
In addition, most of the documents I work on are in landscape mode already (typically 17"x11", 36"x24", 42"x30", or bigger), so why try to squeeze them into portrait mode?
