Another big draw to me is that the checkout process is fast and efficient. Take a look at the packaging and you will notice the barcodes are massive to facilitate rapid scanning.

For most of human history the population growth rate was limited by the food supply. Currently in most developed countries it is limited toby individual decision-making. How long can that realistically last? Surely any genetic factors infl

Based on this equation, shouldn't high speed trains consume less energy since they travel so much slower than planes (3x speed = 9x drag)?

I think it would sound more metaphorical if you removed the indefinite articles, instead starting with "The river cuts through rock"

I would agree that American policies have increased the size of our healthcare sector, but is this really something that can be attributed to free market decisions? How much more growth can we handle when it is already 18% of our GDP ($3.4

1. The USA has the best doctors and hospitals. The marginal benefit to having better doctors and hospitals is completely dwarfed by their higher prices. Would you be willing to pay 2x to have a 5% better chance of no complications on a surg

Not quite yet, orbital missions are much higher energy than lobbing something to space. Specific energy of New Shepard booster at apogee: ~1000 KJ/kg Specific energy of Falcon 9 booster at MECO: 2500 - 3400 KJ/kg

Energy and momentum are always conserved. Elastic collisions conserve kinetic energy. This is helpful to know because you can predict the final speed of the two objects after the collision.

The rest of them. Lithium is only the electrolyte. They also need cathode and anode materials. Specific energy of gasoline: 46.4 MJ/kg Specific energy of high end Li-ion batteries: 1.3 MJ/kg
