Earlier quoted context omitted.

And, by association, F = m*V^2 The risk of serious injury in an accident increases exponentially with speed. This is especially true for pedestrian victims.

You probably mean E = 1/2 m v^2 https://en.wikipedia.org/wiki/Kinetic_energy#Kinetic_energy_...

You can harmlessly spread a lot of energy difference over a large enough time, or a large enough surface.

The most relevant concepts are probably impulse [1] and inelastic collision [2].

v = dx/dt If you are driving 5 miles across town (dx), and you average 25 mph (v), it will take you roughly 5/25 hours, or 12 minutes (dt) to get there. By driving 50 miles per hour, you get there in 6 minutes. Is it worth the risk to yourself and others (bikers and pedestrians) to save 6 minutes? If you are driving to work and it normally takes you 30 minutes to get there by going 60 mph (30 miles), then if you go 8…

Dangerous driving will eventually introduce one to another familiar, but much more devastating, concept: a = dv /dt.

With an extremely small value for dt.

You don't believe in science, you do it.

i.e. the scientific method As in, not this: https://youtu.be/RxyQNEVOElU

In more practical terms, yes you absolutely should trust scientists, and it's important to know the difference between an "appeal to authority fallacy" and "deferral to expertise".

It's still a fallacy. As with most fallacies, it exist because it's a good enough rule of thumb to live our lives.

1.)Quantum entanglement, to instill a sense of appreciation for the unknown. 2.)Astrology, to grant an understanding of the language of archetypes.

Unless you are actually trying to build an apparatus to measure entanglement, and then you get a much better sense of appreciation for the nature of your belief in something that is nearly impossible to conclusively demonstrate above the noise floor, and feels a lot more like prestidigitation and luck than it should.

Am I missing something? This is a link to an article where a bunch of scientists and public intellectuals answer the question, and it provides all kinds of cool content, such as "impedance matching", and the notion that natural selection implies that our DNA can tell us about the environments our genetic ancestors lived in.

Instead of reading, reacting, or engaging with any of those ideas, people are just directly responding to the headline as though this is an ask HN thread. I'm not sure that that's what was intended here?

I would love to hear people talk about this "genetic book of the dead" idea. For instance, the terrifying drowning reflex that people have, there must have been scenarios in our evolutionary past where that happened often enough that this mutation came in handy, which is haunting to think about. I would love for this thread to be a discussion of the ideas presented in the article.

Organic chemistry. Most of the stuff barely requires high school math to understand and is fundamental for health and nutrition are your responsibility to take care of, not your doctors'. As a corollary, macro nutrients.

How computer works from logic gates and up. (I think it was in the article under boolean logic) This one actually requires high school math to understand, but not that much. Knowledge is power and tech is everywhere in our life and society. Democracy as we know it can't continue to exist if the power is in the minds of a few technocrats.

Time is one thing. Going fast is also just plain fun.

It really is! But that is why we have track days. There really is no excuse for doing on a public road.
