Don't bikes stay upright because they are moving to fast to fall over or something?

>>8682338
A bike stays upright because rotations of the weels create a magnetic field and gravitation adjust itself to that.

Ice molecules are packed together in such a way that it reflects friction over the surface. The same way a spherical mirror reflects light over its surface.

Conservation of angular momentum.
The pressure from your feet melts a tiny layer of the ice.

Bikes don't stay upright due to the angular momentum of the wheels, retard.

I have a better question: What CAN science answer where that answer is not discredited a generation or two later?

Why?

>>8682338
>>how bikes stay upright

Bikes tend to stay upright due to the caster effect. Some folks are now going on about the front-loading of the frame and all, but thelr argument seems in error.

>>8682340
No. You can stay upright on a bike that is barely moving at all.

Water, pretty uniquely, expands right as it freezes.

If you exert pressure on it, it cannot remain expanded and melts. The pressure of your foot stepping onto an unexpected ice patch, or the pressure from your car tires, or the blades of an ice skate, causes the creation of a thin film of liquid water on which you can slide along the sidewalk, flailing like a retard, skid sideways into oncoming traffic, or win Olympic gold.

If it gets too cold, by the way, the effect stops working.

>>8682338
how does a unicycle stay upright for that matter ? especially when gravity insists on pulling it down to the earth ?

>>8682384
Again, these are all theories, it hasn't been proven

>>8682386
>The pressure from your feet melts a tiny layer of the ice.

That's been disproven as well.

If you ask "how does something work" in physics then you will basically always get an answer

if you ask "why does this thing work" that's a stupid question for philosopher/wankers to answer

first question isn't even why, and how is the second a philosophical question rather than a scientific one?

>why is ice slippery

I'd agree with him that this is mainly a philosophical question because 'why' questions necessitate explaining the concept(s) used to explain the first question, then explaining the concept(s) used to explain that, and so on, until you hit bedrock, which will inevitably be philosophical in nature, e.g. epistemology.

I tried to think of a 'why' question that doesn't end up with the answer 'that's just the way it is', but I was unable to. Can you?

>>8682338
>>how bikes stay upright
They don't stay upright: there are constant course corrections because the bike is always falling to one side, but by shifting our weight or turning the front wheel the bike leans to the opposite side, then we correct again.

>>why is ice slippery
Different molecules have different degrees of resistance. It should be expected that some molecules will have more drag and others less. The question should be "why is their resistance."

Physicists still don't have a mechanical explanation for what 'G' is in Newton's famous equation.

> http://iopscience.iop.org/article/10.1088/0034-4885/60/2/001/meta

> "Improvements in our knowledge of the absolute value of the Newtonian gravitational constant, G, have come very slowly over the years. Most other constants of nature are known (and some even predictable) to parts per billion, or parts per million at worst. However, G stands mysteriously alone, its history being that of a quantity which is extremely difficult to measure and which remains virtually isolated from the theoretical structure of the rest of physics."

>>8683987
I disagree.

Let's say the question is 'why is ice slippery'? The conventional answer is that through some mechanism or other, ice is slippery because a film of water occurs on the outside of the ice through the interaction with whatever object is on top of it.

This answer isn't satisfactory, we've only moved the question from 'why is ice slippery' to 'why does water on the surface of ice cause it to be more slippery'. Now you'll be forced to invoke the concept of friction, and it'll soon become apparent that you'll never get anywhere with this line of reasoning, because at some point you will have to concede that the explanation is 'that's just the way it works'. It's now fully become a philosophical question.

Of course, as you say, in day-to-day conversation most people would be satisfied with the answer that the layer of water on the ice causes it to be more slippery, but this is just an appeal to intuition, and it doesn't even hold in all cases.

This is why science doesn't concern itself with 'why' questions, but rather with 'how' questions. With 'how' questions you've implicitly established the framework you're using to explain any phenomenon, and you won't be forced to explain ad nauseam or cross into philosophical territory.

Take any of the fundamental forces, for instance. Nobody can answer you 'why' e.g. gravity works, the answer is that it's just a property of our universe. Most people (I hope) can tell you how gravity works, on the other hand.

>>8685554
Because gravity is a weak force ypu retatd. The constant comes from the fucking units ypu use.
