How about producing electricity with a power tower?

Governments are not responsible for stopping variantsIt appears that the UK restrictions will continue for another couple of weeks, because the government didn't think it was responsible for controlling variants either.
Why the median does not change?The median is quite reliable at finding the "middle value" of a distribution, ignoring the outliers
Does an average divided by the total make sense?I have seen an application for the inverse: Total/Average.
if there were mountains, in past ages, which exceeded the height of our present-day highest mountain, EverestThere is one, today - in Hawaii.
But the best model of anything of course is the actual data.That is true - but tables of data are hard to read.
One way to analyse this, is to take the average of day one and day two and find the difference. Would that be accurate given than the average may not be a good overall approximation for every distributionOne factor that makes it hard to compare is that you have a 3-hour "normal" flight time mixed in with a 2 hour "abnormal" flight delay.
There are three kinds of lies: lies, damned lies, and statistics.There are many traps in statistics, and its better to understand a bit about the traps, so you can use statistics more effectively (or lie about them more effectively...)
why does the equation account for the momentum of both fuel AND rocket, if the fuel's momentum doesn't really matter once it has been used to propel the spacecraft?Physicists really like "conservation laws", because they tell you something about the system which you wouldn't know without the conservation law (or you would have to measure every time).
If (a mountain is) too tall, the pressure at the bottom of the mountain will ... cause the crust in the area to become depressed, lowering the height of the mountain above sea level.In fact, mountains are like floating icebergs - most of their mass is below, rather than above the surrounding surface...
4) The Mass of the Nucleus has no role...One simple model of a molecule is to imagine all the atoms joined together with little springs.
5) Once Covalently Bonded, the Hydrogen Atoms do vibrate Slightly.
But then How is it that the Nucleus Attraction is more powerful than the Electron Repulsion?The Hydrogen electron and the nucleus have equal and opposite electrical charges, so the atom is electrically neutral, overall.
Couldn't the evidence in a graph, be presented in "digital" format, ie as just tables of numbers? Is it because graphs make it easier to see the underlying mathematical processes.Yes, humans are a very visual species.
