The momentum is the same, the impulse (and therefore forces) are very different. The bullet is propelled down the barrel gradually - the force is spread through the entire time it takes the bullet to travel the length of the barrel, the reaction forces are applied to the stock gradually, and spread over the area of contact between the shooter and the gun.

A bullet stopped by a vest/plate has a much larger impulse. The bullet needs to be stopped essentially immediately, rather than gradually slowed down over a length equivalent to a rifle barrel, otherwise it kills you. The force is also more concentrated, occuring over the cross-sectional area of the bullet, rather than over the entire contact surface with the rifle.

The issue isn't forwards, it is down.

You have a tungsten rod held in a clamp on a satellite in a nominally stable orbit. Releasing the clamp just means the tungsten rod is now in essentially the same nominally stable orbit as the satellite.

To deorbit it, you need to meaningfully change its velocity. As tungsten is very dense, that takes a lot of fuel. The more fuel that is used, the sooner the rod will hit the ground and the higher the angle.

Simply dropping it means you have to wait months or years for the orbit to naturally decay, a lot of energy will be lost to atmospheric friction, and there is little control over the impact point. Not exactly what you want in your WMD.

Dropping anything in orbit just means it is still in orbit.

You'd need a lot of fuel to deorbit that cube on a steep trajectory.

2000 Bezos or about 4x the GDP of the planet.

People just need to invest and stop blaming others for being broke SMH.

Invest one penny at 3% per year, who can't afford one penny? You'll have $68 billion in just one thousand years. Poverty is a choice.

Building out more and more renewables doesn't mean anything if emissions aren't falling - and they aren't. Since 2021, nearly 4 full years, the world has closed less than 1% of active coal power plants.

The buildout of renewables has arrived hand-in-hand with an increase in total energy usage. The energy mix has improved greatly in favor of renewables, tons of CO2 per KWh is way down, unfortunately we just use more KWh so total emissions are still rising.

Everything in the meme is a leading indicator for positive change, which is wonderful, but the actual change needs to materialize on a rather short timetable. Stories about happy first derivatives don't count for much.

But if you could see them, they could see you ...

Yes, you. And me. And probably most of the people reading this, who live in the US or another Western country

Not quite. 1% of global population is ~80 million people. There are about a billion people in the highly developed nations (US, Canada, Western Europe, Japan, South Korea, and some minor others). So the top 8% of the golden billion, if we assume all in the US, the top ~25% of the country.

You are definitely better of snacking on peanuts than, say, Doritos. It's not that they are a bad food, they just don't have a great macro balance if they are the major component of a diet. From this unvetted comparison they don't seem to be too bad compared to other nuts.

If someone really wanted to get most of their calories from peanuts, they would probably want to supplement with something like pea protein powder and some high-fiber greens (or even beans). This would allow for keeping carbs relatively low while having a more even balance between fat and protein intake. Not quite keto, but not the typical high-carb western diet.

I agree, but at least nuts are high in unsaturated fats, which have some rather solid clinical backing as being healthy. Obviously still energy-dense, and if nuts are used a primary protein source it will likely be difficult to stay within a restricted caloric budget.

E.g. if you want to follow the government recommendation and have 20% of your calories come from protein, peanuts will fall short as only 18% of their calories are sourced from protein (79% from fat). 349 grams of peanuts (about 3/4 of a pound) has 2000 calories and 91 grams of protein - with 175 grams of fat.

The argument the person above you is making is that they also profit off people who never file claims in the first place. In fact those people are more profitable since they do not consume labor to process claims.

The Byzantine system of rules and coverage exemptions exists to disincentive people from filing claims just as it exists to give leeway to deny them.

Of course the overall point that paid claims must be less than premiums charged (and investment income) is correct.

The world bank isn't involved so much in printing money - that's central banks like the US Federal Reserve or European Central Bank.

They do love to force developing nations to adopt US-style capitalism by withholding loans for needed development projects. They also focus far too much on increasing GDP at all costs and do not give really any weight to increasing living standards or reducing inequality. Basically, think loans to institute Reaganomics and you won't be too far off.

The loans pay for large capital projects (power plants, large-scale irrigation, etc) that are built by the state and then mandated to he handed over to private entities that then charge rents and extract wealth. Not every loan and program is bad, but there's plenty to give pause when they are involved in a project.

Beyond making them look horrible, they were marching towards a court ruling against the forced arbitration clause.

Once there is a precedent for the clause being unenforceable, the clause ceases to be a deterrent to legal action - every claim would be litigated at the very least to settle the question of whether arbitration is required in a specific case.
